During osmosis A) pure solvent diffuses through a membrane but solutes do not. B) pure solutes diffuse through a membrane but solvent does not. C) pure solvent and a solution both diffuse at the same time through a membrane. D) gases diffuse through a membrane into a solution and build up pressure.
Answer:
Explanation:A.
The net movements of solvent from the region of higher water potential (solvent) to a region of lower water potential(solute) through a semipermeable membrane is called osmosis. It is a peocess where the solute dissolved in the solvent and the resulting solution pass the selective permeable membrane,A selective permeable is the type which allows water,gases, and non polar molecules to pass through, but restrict polar and other large molecules through its walls.
Generally during osmosis,the water molecules and solute molecules interacts.These interaction ,due to dipole dipole effects of the water molecules, reduced the pressure of water on the solute in solution .Consequently, the water molecule of the pure water (the solvent )exerts more pressure on the weaker solution i,e higher water potential
Hence,this pressure forces water molecules across the semi permeable membrane,from higher water potential to lower water potential.It is the major biological process of plants and animals.
In a sample population of people, 36% have the recessive trait of "free" earlobes (q2). What is the frequency of the dominant allele for attached earlobes, p?
a. 0.40
b. 0.64
c. 0.10
d. 0.24
Answer:
Explanation
Given that 36% are recessive in traits
100-36 = 64% for dominant traits considering a whole population to be 100%
P=dominant allele
q= recessive allele
P2= dominant genotype
q2= recessive genotype
according to hardyweinberg principle, p+q=1
64/100= 0.64 frequency for dominant traits or genotype, therefore
p2=0.64
then
P=√0.64
p= 0.8
Therefore, dominant allele frequency (p) for the population is 0.8
Option B is correct. The frequency of the dominant allele for attached earlobes, p is 0.64
Let the recessive trait of "free" earlobes be q2Let the dominant allele for attached earlobes be "p2"Hence p + q2 = 1 according to hardyweinberg principle
Given the following parameters:
population of those with recessive traits = 36% = 0.36
p = 1 - q2
p = 1- 0.36
p = 0.64
Hence the frequency of the dominant allele is 0.64

A cline:
a. is continuous variation that follows a geographic continuum.
b. is variation that falls into discrete categories.
c. was used to describe human variation as early as the Renaissance.
d. describes the pattern of occurrence of trisomy 18.
Answer:
The correct answer is - option A is continuous variation that follows a geographic continuum.
Explanation:
A cline is a slow change in the physical and genetic traits of a population or species across a geographical difference or gradient. If a species present in a very large area, there would be some members live on different environmental condition in comparison to others.
By this gradient members of species show continuous variation that follows a geographic continuum. For, example, In a species of warm-blooded animals have large body size in cooler area than in warmer area.
Thus, the correct answer is - option A is continuous variation that follows a geographic continuum.

Which of the following best describes the flow of energy in the Everglades food web shown below? (4 points) Diagram for an everglades food web. The food web contains the following organisms: American alligator, egret, raccoon, carp, Key deer, insects, Southern leopard frog, mangrove, and sawgrass. Mangrove is at the bottom of the food web, with arrows pointing to Key deer and insects. Sawgrass is also at the bottom of the web, with an arrow pointing to insects. Key deer, insects and Southern leopard frog are on the next level up. The Key deer has an arrow pointing to American alligator. The insects point to egret, carp, and Southern leopard frog. The Southern leopard frog points to the American alligator and the raccoon. The egret, carp and raccoon all points upward toward the American alligator. The carp also points to the egret. The American alligator is at the top of the food web. Mangrove → insects → carp → American alligator; about 90 percent of the energy in one trophic level is transferred to the next trophic level. Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level. American alligator → carp → insects → mangrove; about 10 percent of the energy in one trophic level is transferred to the next trophic level. Egret → insects → mangrove → key deer → American alligator; about 90 percent of the energy in one trophic level is transferred to the next trophic level.
Answer:
Although there is no diagrammatic representation of the food web but the question can be answered based on the provided information. The answer is:
Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.
Explanation:
Food web is an interconnected food chain i.e. a series of food chains clustered together. A food web represents the various ways one organism can feed on another in a cycle. Since a food web consists of many food chains, energy is transferred when one organism feeds on another (flow of energy).
Just like a food chain, a food web begins with a PRODUCER, which is an organism capable of producing its own food via photosynthesis. This is the case of mangrove and sawgrass in this depicted food web as they are both producers and hence, must start the food web i.e. be at the bottom of the food web. Organisms called CONSUMERS feed on producers and one another to obtain energy. Consumers can be primary, secondary or tertiary depending on the organism they feed on. Primary consumers feed directly on producers, secondary consumer on primary and tertiary consumers on secondary, in that order.
This accounts for why the American Alligator is at the top of the food web because it is a tertiary consumer.
However, as organisms feed on one another, only about 10% of the available energy is transferred because most of the energy (about 90%) has been used for metabolic processes and hence, lost as heat.
Therefore, the best description for the flow of energy in the Everglades food web is:
Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.
Sawgrass is the producer and must begin the energy flow, followed by a primary consumer (insect). Feeding continues in that order until the tertiary consumer (American alligator) is reached.
Answer:
b) Mangrove → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.

One of the procedures for cloning foreign DNA segments takes advantage of restriction endonucleases such as HindIII that produce complementary single strand ends (sticky ends). These enzymes produce identical sticky ends on cleaved foreign DNA and on the vector DNA into which you insert your DNA. Assume you have inserted your favorite gene into the HindIII site of the Bluescript cloning vector with ligase, you amplified it in E.coli, and isolated a large quantity of the plasmid with the insert. How do you excise your favorite gene from the plasmid?
Answer:
Restriction endonucleases are utilized to cut the deoxyribonucleic acid at a specific Restriction site. HindIII is an example of Restriction endonuclease. The Restriction site of HindIII is as per the following:
5'A*AGCTT3'
3'TTCGA*A5' (* represents restriction site)
The Restriction endonuclease cuts the particular gene from the foreign DNA and produces numerous fragments with the sticky ends. The part of the outside DNA which contains the gene of intrigue or a particular gene is ligated with the plasmid.
On the off chance that foreign DNA and plasmid DNA are separated by the same Restriction endonuclease, they will create sticky ends integral to one another. In this way, the segment of foreign DNA can be ligated to the plasmid DNA by the assistance of DNA ligase at the integral sticky end to shape a recombinant DNA.
Additionally, by the assistance of the same Restriction endonuclease for example HindIII for this situation, the recombinant plasmid can be treated with a similar Restriction endonuclease to extract the ideal gene or gene of intrigue.

The cross AB/ab X ab/ab produces the following progeny: AB/ab 391, ab/ab 401, aB/ab 406, Ab/ab 386. From these data, one can conclude that the A and B loci assort independently.
A. True
B. False
Answer:
B
Explanation:
The two loci did not assort independently.
In order to check for independent assortment or otherwise of the result from the cross, Chi-square is used to see if the result conforms with that of Mendelian standard of 9:3:3:1.
Phenotype Observed f Expected f [tex]X^2[/tex] = [tex]\frac{(O - E)^2}{E}[/tex]
AB/ab 391 9/16 x 1584 = 891 [tex]\frac{(391-891)^2}{891}[/tex] = 280.58
ab/ab 401 3/16 x 1584 = 297 [tex]\frac{(401-297)^2}{297}[/tex] = 36.42
aB/ab 406 3/16 x 1584 = 297 [tex]\frac{(406-297)^2}{297}[/tex] = 40.00
Ab/ab 386 1/16 x 1584 = 99 [tex]\frac{(386-99)^2}{99}[/tex] = 832.01
Total [tex]X^2[/tex] = 280.58 + 36.42 + 40.00 + 832.01 = 1,189.01
Degree of freedom = 4 - 1 = 3
Tabulated [tex]X^2[/tex] at degree 3 freedom and 95% level = 7.815
The calculated [tex]X^2[/tex] value is more than the tabulated value. Therefore, we conclude that the outcome of the cross is not in agreement with Mendelian standard and hence, the A and B loci did not assort independently.
The correct option is B.

What Are Blood vessels
Answer:
[tex]\boxed{\mathrm{see \: below}}[/tex]
Explanation:
Blood vessels are vessels that carry blood through organs and tissues. The five types of blood vessels are: arteries, veins, arterioles, capillaries, and venules. The main function of blood vessels is to carry blood throughout the body.
Answer:The blood vessels are the components of the circulatory system that transport blood throughout the human body.[1] These vessels transport blood cells, nutrients, and oxygen to the tissues of the body. They also take waste and carbon dioxide away from the tissues. Blood vessels are needed to sustain life, because all of the body's tissues rely on their functionality.[2]
There are five types of blood vessels: the arteries, which carry the blood away from the heart; the arterioles; the capillaries, where the exchange of water and chemicals between the blood and the tissues occurs; the venules; and the veins, which carry blood from the capillaries back towards the heart.
The word vascular, meaning relating to the blood vessels, is derived from the Latin vas, meaning vessel. Some structures – such as cartilage, the epithelium, and the lens and cornea of the eye – do not contain blood vessels and are labeled avascular.

5. fewer amounts of the hormone
6. parathyroid hormone-like hormone (PTHLH)
7. the thyroid and parathyroid glands
8. Steroid hormones are produced from cholesterol, while nonsteroid hormones are produced from amino acids.
Explanation:
Hormones are signaling molecules secreted by the body to control cellular activities The endocrine glands are glands that don't have ducts to carry their secreted products (hormones) to the surface. Endocrine glands include the hypothalamus, ovaries, testes, pancreas, adrenal glands, parathyroid glands, pituitary gland, pineal gland, thymus and thyroid glands. The pituitary gland is an endocrine gland that secretes many hormones into the bloodstream, which are capable of controlling the functioning of other organs and glands. During the puberty stage, this gland secretes LH and FSH gonadotropin hormones that affect male and female gonads in order to activate the production of sex hormones. The adrenal glands secrete cortisol, which is known as the stress hormone. These glands also produce adrenaline which regulates visceral functions such as, for example, respiration. The parathyroid hormone-like hormone (PTHLH) is generated by epithelial cells and plays important roles in fetal and adult tissues, (i.e., cell proliferation, differentiation and morphogenesis). The thyroid gland regulates body temperature, while parathyroid glands control the calcium level in the blood by secreting the parathyroid hormone (PTH). Steroid hormones are lipidic hormones known to bind steroid receptors and they can easily cross the cell membrane, while non-steroid hormones cannot diffuse across the cell membranes and they are secreted by the endocrine system.
Which of the following is a human-related release of greenhouse gases?
O A. Wild animal respiration
OB. Volcanic eruptions
O C. Intensive agriculture
O D. Solar cycles
It’s A
Answer:
C
Explanation:
I'm pretty sure it's actually C and not A. It's asking for human-related release from greenhouse gases. Humans don't cause volcanic eruptions and aren't in control of wildlife's respirations. The solar cycles has to do with the magnetic flux that rises to the surface of the sun and lasts 11 years. Intensive agriculture increases pollution which harms the environment.

6)fish
Answer:
Yeast - Fungi Penicillium - Fungi Rhizobium - Monera mushroom - Fungi Amoeba - Protozoan fish - AnimaliaExplanation:
The Fungi Kingdom is a kingdom composed, as the name says, of fungi, which are organisms represented by many species, among them: yeasts, mushrooms, molds, Penicillium and others. As you already know, fungi are eukaryotic and multicellular organisms (with the exception of yeasts).
The monera kingdom is the kingdom formed by bacteria and also has several species as members. Among these species we can mention the Lactobacilli, Escherichia coli, Rhizobium (nitrogen-nodulating bacteria, very important for the natural fixation of nitrogen in legumes), among others.
The kingdom of protozoa is very diverse and even has an organism that does not have any type of genetic, structural and morphological similarity, but in most cases, the members of this kingdom are heterotrophs, eukaryotic and unicellular organisms. An example of this is amoebas.
The animal kingdom is made up of all animals, the most diverse and populous kingdom. All animals belong to that kingdom, including fish.

New mutations can also occur randomly, so there’s a chance that children of parents who didn’t inherit the gene for Huntington’s can develop a mutation in the gene that causes Huntington’s disease explain how protein synthesis contributes to the symptoms of the disease
Answer:
It depends on the mutation rate
Explanation:
Mutations are genetic changes that occur naturally by errors during DNA replication which are not repaired by the DNA repair mechanisms. When a mutation occurs in the germline line, it may pass to the next generations and thus perpetuate itself. Huntington's disorder is an autosomal dominant disorder associated with a trinucleotide repeat mutation in the huntingtin (HTT) gene localized on chromosome 4, which encodes the Huntingtin protein. It has been shown that the high levels of Huntingtin are linked to Huntington's disorder, thereby it is believed that this mutation might be associated with a higher expression of the HTT gene.

B) to create interesting looking pets.
C) the florescent cells can help track the movement of cells.
D) to create light in a dark laboratory.
The answer is C) The fluorescent cells can help track the movement of cells.
Explanation:
Fluorescent animals such as rabbits have been created by using the GFP gene that is the Green Fluorescent Protein, which occurs naturally in the Aequorea Victoria jellyfish. In this way, the protein was extracted from jellyfish and used in mammals, including rabbits. This particular use of genetics does not only make animals glow in the dark but also helps geneticists to study cells as it makes visible how cells move, develop or change. Thus, the correct answer is C.
