the answer is A the isolation of two populations of the same species

Explanation:

took the quiz got an 97

The isolation of two populations of the same species.

Specification is the formation of new and distinct species in the course of evolution.

This speciation involves the splitting of a single evolutionary lineage into two or more genetically independent lineages.

Speciation from biogeographic isolation can result from the isolation of two populations of the same species.

Explanation:

Answer:

This called crude density. ... Density measure in terms of the amount of area available as living space is ecological density.

The correct answer is protection because the integumentary system provides protection.

The skin and other parts of the integumentary system work in concert with other organ systems to maintain homeostasis. The skin works with the immune system to protect the body from pathogens by acting as a physical barrier to microorganisms.

Description: This feature is usually called the exoskeleton because it can be the hair of the nail, or basically the inner one that grows naturally on the outside, but in this case, it is not the exoskeleton, It is there to protect.

The skin has three main functions: protection, regulation, and sensation.

Thus it concludes that the integumentary system has the ability to provide protection.

Answer:

The answer is C!

Explanation:

Because i just had this on a test

Answer:C) light caused the elodea plants to photosynthesize, releasing O2 gas

Explanation:

Got it right on my test

Students carried out the experiment demonstrated in biology class, and after 24 hours, they noticed gas had accumulated in one of the inverted test tubes, which is the oxygen gas produced by the plant during the photosynthesis process. 

There are many experiments that demonstrate photosynthesis, such as when the elodea plant is kept in the sunlight, the gases are released and collected in the tube, and when tested, it is discovered that this gas contains oxygen, proving that the plant produces oxygen and glucose in the presence of sunlight.

Hence, students carried out the experiment demonstrated in biology class, and after 24 hours, they noticed gas had accumulated in one of the inverted test tubes, which is the oxygen gas produced by the plant during the photosynthesis process.

Answer:

B. codominance

Explanation:

I know this for sure

Answer: Black allele has frequency of 0.14.

              Red allele has frequency of 0.86.

             The frequency of heterozygotes is 0.241

Explanation: Hardy-Weinberg model states the frequency of alleles in a population will stay in equilibrium as long as there are external influences. It is also used to determine alleles frequencies using the following equations:

[tex]p+q=1[/tex]

[tex]p^{2}+2pq+q^{2}=1[/tex]

p represents frequency of dominant allele;

q represents frequency of recessive allele;

2pq is frequency of heterozygotes;

For the frequency of red allele, which is dominant, we can use:

[tex]p^{2}=\frac{37}{13+37}[/tex]

[tex]p^{2}=\frac{37}{50}[/tex]

[tex]p^{2}=0.74[/tex]

[tex]p=\sqrt{0.74}[/tex]

p = 0.86

For the black allele:

[tex]p+q=1[/tex]

[tex]q=1-p[/tex]

[tex]q=1-0.86[/tex]

q = 0.14

Frequency of heterozygotes is

2pq = 2(0.86)(0.14)

2pq = 0.241

Frequencies for a population of Muscovy ducks are 0.86 for red allele, 0.14 for black allele and 0.241 for heterozygote.

The correct pathway that the food travels during digestion is Mouth, esophagus, stomach, small intestine, large intestine. The correct option is D.

The gastrointestinal tract (also called the digestive tract). This long tube of organs serves as a conduit for food to pass through the body. It includes the esophagus, stomach, and intestines and runs from the mouth to the anus (where poop comes out).

The digestive system's alimentary tract is made up of the mouth, pharynx, esophagus, stomach, small as well as large intestines, and rectum.

The alimentary tract's primary function is to convert food into absorbable particles and transport them to the body's other organs.

The correct digestive pathway is the mouth, esophagus, stomach, small intestine, and large intestine.

Thus, the correct option is D.

Crossing over in which alleles are exchanged

Answer:

Linked Genes Violate the Law of Independent Assortment. Although all of Mendel's pea characteristics behaved according to the law of independent assortment, we now know that some allele combinations are not inherited independently of each other.

Explanation:

PLz, mark me as a brainlist :)

Mendel studied the transmission of genes in peas(pisum sativum) that were placed on different chromosomes. During meiosis there are two types of recombinations that make sure the offspring is different from the parent. First intrachromosomial recombination (crossing-over)where genetic material is exchanged between chromosomes. And interchromosomial recombination when homologous chromosomes are separated.

In Mendel's experiments only interchromosomial recombination was considered, but when Thomas Hunt Morgan experimented with Drosophilla Melanogaster he didn't get the same results because he focused on genes that were placed on the same chromosome. In this situation crossing over influenced the results.

There is a population of 1,000 wolves. Over the course of a year, 100 wolves are born. The birth rate is 10 births per individual per year. The correct option is b

Birth rates of organisms decline and mortality rates increase in density-dependent populations due to numerous factors affecting the rate of reproduction and survival.

When there is a disease, competition, or predation in that organism, it has a higher mortality rate and a lower growth rate. These three factors reduce the birth rate and raise the death rate in an organism's population.

If both the death and birth rates are low, the population will not grow significantly and will remain relatively stable.

1000 / 100 = 10

Therefore, the correct option is b, 10 births per individual per year.

Answer:

The more protein channel or carrier a cell has, the faster will be the transport of a specific compound. In other side, lower will be the transport of the rest of compounds, such as O2, H2O.

Explanation:

A protein channel or a carrier protein acts as facilitators in the transport of compounds. The compounds who are polar can't pass easily, or can't even pass, trough the plasmatic membrane, because of it's nonpolar center. So, the cell needs to provide a way for the polar compounds who are needed inside or outside of the cell, thus we have the proteins channel or carrier. They form a polar way for the polar compounds pass into or out the cell.

However, the more proteins we have to transport, less space the membrane will have for the others compounds, because every transport protein just acts with a specific compound or others very similar to it.

The quote refrences to the fragility of our enviorment and how that balance is to not be disrupted. That no matter how small,every detail affects that balance and is not to be tampered with. It is the same in the food chain,the elimination of even the smallest of species can have devastating effects on an ecosystem. That is why it is important to preserve resources and respect all life. an example of that balance being disrespected in the movie would be the scene where the once beautiful valley was barren and dry due to the hyenas destroying and using up all of the resources, thus destroying the balance of life and bringing famine to their lands.

Explanation: The circle of life man

When a balance is not respected then it leads to destruction of the whole ecosystem not a single organism.

This quote is related to the concept of the food web, pyramid of energy, and the pyramid of numbers because every organism is dependent on other organism for its survival. If that organism is eliminated from the ecosystem, then the organism that feeds on it also die.

If this balance is not respected and maintained then the whole ecosystem is destroyed because every organism is dependent on othe organism.

So we can conclude that when a balance is not respected then it leads to destruction of the whole ecosystem not a single organism.

Answer:

Transpiration is the process of evaporation of water from the leaves and stems to the atmosphere. The stomata close when the guard cells shrink, which in turn ceases the transpiration. Opening of stomata allows the process of transpiration, so the root cells do not die.

But if it can't close:

The downside to wide open stomata is increased water loss (transpiration). So stomata of cool-season turf grasses have decisions to make. The plant needs to capture and store energy via photosynthesis, however, excessive water loss through transpiration can result in plant injury or death.

It's a bad thing.
