I neeed help pls answe them plssss
Answer:
Autosomal dominant and recessive: Autosomal dominant states a pattern of inheritance in which an individual carries one normal gene and one copy of a mutant gene while autosomal recessive states a pattern of inheritance in which an individual have two copies of the mutant gene.
Incomplete dominance: Incomplete dominance states a heterozygous condition in which both the alleles present are partially expressed and produces intermediate phenotype.
Codominance: In codominance and individuals receive alleles, if both the alleles are different including dominant and recessive, dominant allele will be expressed while recessive will be masked.
Multiple alleles: organisms with multiple alleles exist with two copies of every gene present in a population with variation in genes.
Sex linked gene: In humans and some other organisms, sex linked genes are influenced by genes on the X chromosome. for example: If a gene is present on the X chromosome only and not the Y chromosome.
While viewing the Electron Transport Chain simulation in Labster, it showed how electrons from electron carriers are 'dropped off' at the beginning of the process.Why did it show two different pathways electrons can take during this simulation
Electrons can be either passed on to the electron transport chain by NADH⁺ at the first complex (NADH⁺-coenzyme Q oxidoreductase) or at the second complex(FADH⁺-coenzyme Q oxidoreductase). I think that's what you're referring to.

Identify two structural features of purines and pyrimidines. Purines contain only three ring nitrogen atoms. contain only two ring nitrogen atoms. contain four ring nitrogen atoms. contain two heterocyclic rings. contain one heterocyclic ring.
Answer:
1) Purines contain only four ring nitrogen atoms while Pyrimidines contain only two nitrogen ring atoms
2) Purines contain two heterocyclic rings while Pyrimidines contain one heterocyclic ring
Explanation:
Purines and Pyrimidines are two classes of nitrogenous bases that make up nucleic acids. They are both heterocyclic aromatic compounds which contains nitrogen atoms in their structure. Although, they are similar but have distinct features namely:
Purines are ring molecules which consists of four (4) nitrogen atoms in their aromatic structure. They are structures with two heterocyclic rings consisting of five (5) carbon and four (4) nitrogen atoms. Adenine and Guanine are the purines in nature.
On the other hand, Pyrimidines are another ring molecules consisting of two (2) nitrogen atoms in their aromatic structure. Their only ring i.e. 1, is also heterocyclic in nature and contains four (4) carbon and two (2) nitrogen atoms. Cytosine, Thymine and Uracil are the pyrimidines.

In the newly engineered cell created by the researchers at the JCVI, what was derived from a previous cell, partially supporting one aspect of cell theory?
Answer:
Cells can only derive from pre-existing cells.
Explanation:
The cell theory has three major postulates: 1-all organisms are composed of cells, 2-the cells are the basic unit of all living forms, and 3-the cells derive from pre-existing cells. In 2010, the J. Craig Venter Institute (JCVI) designed in the laboratory a synthetic bacterium that is able to auto replicate himself, and thereby supporting the third statement of the cell theory. This bacterium was named as Mycoplasma mycoides JCVI-syn1.0 and its creation represented a milestone in synthetic biology. M. mycoides is a bacterium that has only 473 genes coded by 531,000 bases pairs (bp), this being one of the smallest genomes of all living forms.

The Interests Theory Approach. Advocates of the interests theory approach argue that the principal function of human rights is to protect and promote certain essential human interests. Securing human beings' essential interests is the principal ground upon which human rights may be morally justified.
Why is oceanic crust subducted under continental crust?
A. Oceanic crust is moving faster than continental crust.
B. Oceanic crust is denser than continental crust.
C. Oceanic crust is less dense than continental crust.
D. Oceanic crust is older than continental crust.
Answer:
B.) Oceanic crust is denser than continental crust.
Explanation:
Oceanic crust is denser, so it is subducted under the continental crust. The less dense magma then rises up through the continental crust, then it's further increasing the size of the continental crust and then maintaining it's lower density than the oceanic crust, which then causes subduction.
I hope this helped. I am sorry if you get this wrong.

Which is the pair of the enzyme activities most significantly affected by glucagon- and insulin-dependent phosphorylation and dephosphorylation of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFKFB)?
a. hexokinas ::::: glucose-6-phosphatase
b. phosphofructokinase ::::: Fructose-1,6-bisphosphatase
c. pyruvate kinase :::::: pyruvate carboxylase
d. glycogen synthase ::::: glycogen phosphorylase
e. None of these
Answer:
b. Phosphofructokinase; Fructose-1,6-bisphosphatase
Explanation:
Glucagon is a hormone which functions to initiate gluconeogenesis whwreas insulin functions to initiate glycolysis.
Fructose-2,6-bisphosphate (F26BP) is an allosteric regulator of the glycolytic and gluconeogenic enzymes phosphofructokinase-1 (PFK-1) and fructose-1,6-bisphosphatase (FBPase-1).
It stimulates glycolysis and inhibits gluconeogenesis by binding to its allosteric site on phosphofructokinase-1 reducing its affinity for the allosteric inhibitors ATP and citrate .
It is formed by phosphorylation of fructose-6-phosphate catalyzed by phosphofructokinase-2 and is broken down by fructose-2,6-bisphosphatase which are two separate enzymatic activities of a single, bifunctional protein (PFK-2/FBPase-2).
Phosphorylation of PFK-2/FBPase-2 due to glucagon release enhances its FBPase-2 activity thereby stimulating gluconeogenesis and inhibiting glycolysis.
Dephosphsorylation of PFK-2/FBPase-2 due to insulin release enhances its PFK-2 activity, thereby stimulating glycolysis and inhibiting gluconeogenesis.
Without crossing over, the independent assortment of the homologous chromosomes in a cell with these chromosomes will produce two different genotypes. Which are they
Answer and Explanation:
Crossing over occurs during meiosis. When homologous chromosomes are aligned and they stick together by the chiasma point. At this point, the homologous chromosomes chains break and get recombined with the broken portion of its homologous. The result is that one of the progenitor´s chromosome will have a portion of the other progenitor´s chromosome, and vice-versa.
If crossing-over does not occur, the independent assortment of the homologous chromosomes in a cell will produce two different genotypes that equals the ones of the progenitors. So, there will be two genotypes, one of them equals the female´s genotype and the other is like the male´s genotype.

While you are running and approaching your first mile, oxidation of free fatty acids is taking place at the cellular level, allowing you to continue running.
a) anaerobic metabolism
b) aerobic metabolism
c) lactic acid metabolism
answer
B) aerobic metabolism
(Aerobic metabolism is the way your body creates energy through the combustion of carbohydrates, amino acids, and fats in the presence of oxygen. Combustion means burning, which is why this is called burning sugars, fats, and proteins for energy.)
Why do organisms go through the process of meiosis?
Answer:
Meiosis is essential for sexual reproduction and therefore occurs in all eukaryotes (including single-celled organisms) that reproduce sexually. ... These resultant haploid cells can fuse with other haploid cells of the opposite sex or mating type during fertilization to create a new diploid cell, or zygote.
Explanation:
A hypothetical Island lies far from any other landmasses. There are many different types of plants, but only one animal, a beetle plant and feed by chewing leaves. Given that the beetle is not exploiting all the resources on the island, which morphologic trigger an adaptive radiation of the beetles?
Answer:
a mouthpart that can pierce fruits and seeds
Explanation:
An adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms. That being said the most likely morphological change that would trigger this would be a mouthpart that can pierce fruits and seeds. This new change would allow the beetles to consume most of the different resources that the island has to offer such as the different types of plants and fruits which were previously inaccessible to the beetles.
PLS PLS PLS HELP Other than distance from the sun, which factor affects the temperature of a planet? (not just earth) Explain your answer in complete sentences.
Answer:
Another factor besides distance from the sun would be "atmospheric composition".
Explanation:
Other than distance from the sun, atmospheric composition affects the temperature of a planet. Atmospheric composition is the amount of energy that gets to the exterior of a planet. The energy that gets to the exterior of a planet, affects the temperature.
compare the potiential energy stored in lipids proteins and carbohydrates
Answer:
The amount of lipids stored as an energy reserve far exceeds the energy stored as glycogen since the human body is simply not capable of storing as much glycogen compared to lipids. Lipids yield 9 kcal of energy per gram while carbohydrates and proteins yield only 4 kcal of energy per gram.
help asap true or false Uranus orbits the Sun at less than 40% of the speed of Venus.
Answer:
True
Explanation:
The attached image shows a table that displays the eight (8) planets, their respective average distance from the sun and their respective orbital speeds.
The question only relates the orbital speed of planets Uranus and Venus, which is 7km/s and 35km/s respectively.
40% of the orbital speed of planet Venus is:
= 40/100 × 35
= 0.4 × 35
= 14
According to the table in the image, Uranus orbits around the sun at a speed of 7km/s, which is lesser than 40% of Venus's orbital speed (14km/s).
Therefore, it is TRUE that Uranus orbits the sun at less than 40% of the orbital speed of Venus.

According to E. Mavis Hetherington's research, Barney would most likely be categorized as a(n)
A) defeated
B) competent loner
C) enhancer
D) good-enough
The answer to this question is A) defeated
Explanation:
E. Mavis Hetherington is an important Canadian psychologist mainly known for studying divorce and the effects of it. About this, the psychologist proposed divorce is a complex process and has a great impact on those involved. In the case of the spouses, E. Mavis Hetherington proposes four main styles spouses might acquire after divorces such as competent loner, defeated, enhancer, etc.
In the category of defeated this psychologist includes those that do not cope with life after divorce, instead, they experience depression, loneliness, regrets, and other negative feelings, which stop them from thinking positively about the future or adapting to their situation. This category describes Barney because after divorce he feels regretful and depressed; also, he has great difficulty to cope with life or adapt to the situation.
Somatic cells in elephants have 56 chromosomes. How many chromosomes would be carried by the gametes produced by elephants
Answer:
As somatic cells are diploid (2n) 2n=56
gametes receive only haploid set so, n=28
The number of chromosomes carried by the gametes produced by elephants would be : 28
Given that The elephants posses 56 chromosomes in its somatic cells and somatic cells are known as diploid cells ( i.e. 2n ) while the gametes will only carry a haploid set of chromosome ( i.e. n ).
Determining the number of chromosomes contained in the gametes
since ; 2n ( chromosomes of a somatic cell ) = 56
∴ n ( chromosomes contained in a gamete ) = 56 / 2 = 28
Hence we can conclude that The number of chromosomes carried by the gametes produced by elephants would be : 28.

Explain why chemogenetic based methods of regulating cellular signaling result in poor temporal control of biochemical pathways relative to optogenetic based methods.
Answer:
They use different detecting methods to assess neuronal circuits
Explanation:
Chemogenetics is a technique widely used in neuroscience research to explore signaling interactions by means of genetically modified receptors capable of interacting with small molecules. Chemogenetics was first used to determine the function of the chalcone isomerase gene by inducing mutations that altered its substrate specificity. On the other hand, optogenetics is a bioluminescence-driven genetic technique used to control genetically modified neurons that express light-gated ion channel genes. This technique is also used to monitor neuronal networks. In consequence, optogenetic and chemogenetic techniques have recently been combined in order to analyze neuronal circuits, it by analyzing the same actuator molecule.
