1. A dominant gene (A) causes yellow color in rats, the dominant allele on another independent gene (R) produces black coat color. When the two dominants occur together (A_ R_) they interact to produce gray coat color. Rats of the genotype aa are cream-colored. If a gray male and a yellow female, when mated, produce offspring approximately 3/8 of which are yellow, 3/8 gray and 1/8 cream, and 1/8 black, what are the genotypes of the parents
Answer:
Parents: Yellow (Aarr) and Grey (AaRr)
Explanation:
Given:
allele A = yellow
allele R = black,
Heteroozygous = gray
Genotypes of the parents:
yellow (Aarr) - female
gray (AaRr) - gray
cross between these
Parents: Yellow (Aarr) and Grey (AaRr)
Gametes: (Ar, ar) and (AR, Ar, aR, ar)
F1 (Punnet square)
----|----- AR ------|------- Ar ------|------ aR -----|----- ar
Ar | AARr (gray) | AArr (yellow) | AaRr (gray) | Aarr (yellow)
ar | AaRr (gray) | Aarr (yellow) | aaRr (black) | aarr (cream)
Ratio: 3/8 yellow : 3/8 gray : 1/8 cream : 1/8 black
**anatomy & physiology question**
if you are at a 60X magnification and the field diameter is 3.2mm an object that's about 1/4th the size of the field diameter what is the size of the object?
Answer:
0.8mm.
Explanation:
If the size of an object is about 1/4th the size of the field diameter so the size of an object is 0.8mm because the fourth part of field diameter is equals to 0.8mm. Due to knowing field diameter of microscope we can calculate the real size of objects that is too small which can't be seen with the naked eye. So one fourth part of field diameter is equal to 0.8mm.

The correct answer is "Two identical DNA molecules are made that contain one original strand and one paired strand."
Explanation:
The word "conserve" refers to the action of preserving an element. Moreover, the prefix "semi" refers to partial. In this context, DNA replication can be considered as a semi conservative process because the original DNA is partially preserved. This is explained in "Each of the two daughter molecules made during replication contain one strand from the parent molecule and one new strand" because this excerpt shows how in the process each of the cells resulting has at least 50% of the DNA of the original cell. This implies replication does not lead to a completely new cell as part of the genetic material is kept. According to this, this process can be considered as semiconservative because "Two identical DNA molecules are made that contain one original strand and one paired strand."

A student is using a terrarium like the one shown here to study the cycling of
water in an ecosystem.
Which observation would be the best evidence of the water cycle?
O A. Condensation
O B. Predation
O C. Moving animals
O D. Dead plants
Answer:
A- condensation
Explanation:
Condensation would be the best evidence of the water cycle in a terrarium ecosystem. Therefore, option (A) is correct.
What is water cycle?The water cycle is the continuous movement of water between the Earth's surface, atmosphere, and underground. It involves several processes, including evaporation, transpiration, condensation, precipitation, and runoff.
In the water cycle, water evaporates from the Earth's surface into the atmosphere, where it cools and condenses into clouds. These clouds can then produce precipitation, such as rain, snow, or sleet, which falls back to the Earth's surface. Some of this precipitation is absorbed by plants or runs off into rivers, streams, and lakes, while the rest seeps into the ground to become groundwater. This groundwater can eventually be released back to the surface through springs, or it can flow into larger bodies of water.
The water cycle is a vital process for the Earth's ecosystems, as it helps to distribute water and nutrients across the planet and support life. Human activities, such as deforestation and pollution, can disrupt the water cycle and have negative impacts on the environment.

Which of these is the best explanation for why the rock on the ocean floor and the rock on the continent are
NOT the same age?
There has been a lot of erosion on the continent and the older rock has been washed away.
There has been a lot of erosion on the ocean floor and the older rock has washed away.
Due to the movement of the plates, the rocks that make up the ocean floor are pulled inside the earth
more often and are much younger.
Answer:The continental crust is less dense so the oceanic crust subducts back to the mantle. This process explains why the younger rocks are found on the ocean floor. 24.

What is the key activating signal in the TNF receptor signaling pathway that occurs downstream of TNF-alpha binding to the extracellular domain
Answer:
TNF-alpha is expressed as a homotrimer that exerts its activities through binding to two types of receptors: TNFR1 and TNFR2, which are transmembrane glycoproteins characterized by having an extracellular domain with 4 cysteine-rich domains (CRD 1-4) , each with 3 cysteinecysteine disulfide bonds.
Explanation:
TNF-alpha (Tumor Necrosis Factor), which has the characteristic of being a paracrine signaling ligand, is a pleiotropic cytokine that functions as a mediator of immune regulation, the inflammatory response and apoptosis in some cell types. Receptors in this family are involved, with some exceptions, in juxtacrine signaling; that is, both the ligand and the receptor are membrane proteins with extracellular domains through which signaling is established. The cellular responses promoted by TNF are initiated by its interaction with two different types of cell receptors, the type I receptor (55 kDa) and the type II receptor (75 kDa). Both types of receptors are part of the TNF receptor family, members of which include Fas antigen (apoptosis inducer, also called Apo-1 or CD95), CD27 (T-cell activation antigen), CD30 (lymphoma marker Hodgkin) and CD40 (B-cell antigen), which share the characteristic of cysteine-rich sequences in their extracellular domains. This family of cytokines generate cellular responses that include differentiation, proliferation, activation of NFκB and cell death, promoting the aggregation of receptor monomers, that is, they have a transmembrane domain that participates in the solubilization of the receptor and a domain of intracellular death that is involved in signal transduction. The binding of TNF to TNF-R1 induces a signaling cascade through its intracellular death domain, which subsequently leads to the activation of complex I (or inflammatory) of NFkB and proceeds to the transcription of anti-apoptotic genes, pro- inflammatory diseases and apoptosis complex II (caspases).
5. The lion researchers in the film have studied 20% of the park and identified 41 lions. (Show your

a. The entire Gorongosa park is 4,000 km². Approximately how large (in km) is the portion of
the park that has been studied?
ASAP PLSS
Answer:
800 km²
Explanation:
If the researchers have studied 20% of the 4000 km² park, to find out how much of the park in km they have studied, all you have to do is find 20% of 4000.
4000 x .20 = 800
800 km² is your answer.
If the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].
What do you mean by the researcher?A researcher may be defined as a kind of person who significantly carries out academic or scientific research in order to find some unrevealed data and information.
According to the question,
The total area of Gorongosa park = Gorongosa park is 4,000 km²
The area which is already studied = 20%.
Now, you have to find the area that is already studied in km. So, you have to calculate the 20% of 4,000 km².
The area which is already studied = 4000 × .20 = 800 [tex]km^2[/tex].
Therefore, if the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].

All energy comes from the sun. In 2-3 sentences, explain how it is transferred from one organism to another.
Answer:
When the sun rays come down into the atmosphere and the plants on the ground use photosynthesis to reproduce and eat. If an animal, for example, a bunny, eats grass the energy will be transferred to the bunny. If a fox eats the bunny, the energy transfers to the fox. the amount of energy will be reduced each time something is eaten because it keeps being consumed over and over.

In humans, two abnormal conditions, cataracts in the eyes and excessive fragility in the bones, seem to depend on separate dominant genes located on different chromosomes. A man with cataracts and normal bones, whose father had normal eyes, married a woman free from cataracts but with fragile bones. Her father had normal bones. What s the probability that their first child will a) be free from both abnormalities b) have cataracts but no fragile bones c) have fragile bones but not cataracts; d) have both cataracts and fragile bones
Answer:
a) 1/4 or 25%
b) 1/4 or 25%
c) 1/4 or 25%
d) 1/4 or 25%
Explanation:
Both cataracts and bone fragility are dominant conditions and are independently inherited. Let cataracts allele be represented by C and fragile bone by B.
A man with cataracts (CC or Cc) and normal bones (bb), whose father had normal eyes would have the genotype Ccbb. The cataract would be heterozygous because he had a normal eyes father. The affected allele must have been inherited from his mother.
A woman free from cataracts (cc) but with fragile bones (BB or Bb) whose father had normal bone would have the genotype ccBb. The fragile bone would be in heterozygous condition because she had a normal bone father. The affected allele must have been from the mother.
Ccbb x ccBb
Offspring
4 CcBb - cataract eyes, fragile bone
4 ccBb - normal eyes, fragile bone
4 Ccbb - cataract eyes, normal bone
4 ccbb - normal eyes, normal bone
a) Probability that their first child would be from both abnormalities = 4/16 or 1/4 or 25%
b) Probability that their first child would have cataracts but no fragile bones = 4/16 or 1/4 or 25%
c) Probability that their first child would have fragile bones but no cataracts = 4/16 or 1/4 or 25%
d) Probability that their first child would have both cataracts and fragile bones = 4/16 or 1/4 or 25%

2. What color rabbit seemed to camouflage the best in this snow habitat and why? What
color rabbit seemed to camouflage the best in the summer habitat and why?
Answer:
The more an animals color matches their surroundings, the more likely it is for survival. White rabbits fur matches the snow, and brown rabbits fur blend with the dirt
Explanation:
The colors that stand escape the many would be red and blue and the one's camouflage is mostly brown, green, and yellow, swinging on its place and surroundings.
What is the Color rabbit?
The prey that is more delicate in color lasts extended. As the duration goes on, the white prey lasts extended than the blue colors as they blend into their surroundings sufficiently.
The green, red, and orange varied practically extinct over the 3 generations because they could be stained easier and could not blend into their surroundings.
The colors were very necessary for how it influenced the people because the more brilliant the color the more predators it's going to seduce and the colors such as green and brown are more camouflage.
The more an animal's color approximates its surroundings, the more possible it is to survive. White rabbit's fur approximates the snow and brown rabbits' fur in combination with the dirt.
