An animal will choose to eat the prey that offers the greatest energy yield per unit of effort.
The easiest way to understand conduct from an evolutionary standpoint is as a feature that can fulfill the three requirements for evolution through natural selection.
When an organism's own survival and ability to reproduce is put at risk, kin selection is the evolutionary strategy that favors the success of its relatives' procreation. Kin selection can make kin altruism appear to be selfless behavior that has evolved over time.
Overall, the case for reciprocal altruism in species other than humans is tenuous. Nonhuman animals appear to be far more "in the present" than humans, and the majority, if not all, of help-giving behavior can be explained by kin selection or by immediate rewards.

In cats, black fur color is caused by an X-linked allele, while the other allele at this locus causes orange color. The heterozygous allele is tortoiseshell. Normally, only females have the tortoiseshell phenotype because
A. a male inherits only one allele of the X-linked gene for hair color
B. multiple crossovers on the Y chromosome prevent orange pigment production
C. only males can have Barr bodies
D. genetic imprinting prevents males from inheriting tortoiseshell traits from a mother
Normally, only females have the tortoiseshell phenotype because a male inherits only one allele of the X-linked gene for hair color, hence option A is correct.
Why do females have the tortoiseshell phenotype?The males perish during embryonic development, only female cats often exhibit the tortoiseshell phenotype. The X-linked gene governing hair color can only be inherited by males as one allele.
This is so because male cats only have one X and one Y chromosome, whereas two X chromosomes are required to generate the distinctive tortoiseshell coloration of black, orange, and yellow/gold.
Therefore, option A is correct.

C. Temperatures near the equator rise.
D. Warm air sinks to meet.
Turn In

Answer:
B. Cool water flows in to take its place
Explanation:
You want to know what happens when warm water rises in the ocean.
CurrentsIn any fluid, currents will arise from differences in fluid density. When fluid moves out of a space, other fluid flows into that space to fill the void.
Ocean currentsIn general, ocean currents arise from differences in temperature and salinity. Warmer and less saline (fresh) water have less density than colder or more saline water. As a consequence of its reduced density, warmer (or less saline) water will experience pressure moving it upward. It is replaced by water of lower temperature or greater salinity.
When warm water rises, cool water flows in to take its place.
What is photosynthesis? And what is cellular respiration?
(Provide definitions and examples for both)
How are the processes of photosynthesis and cellular respiration connected? Explain how plants and animals mutually benefit each other using these processes.
Answer:
Please read below:
Explanation:
Photosynthesis is the process by which plants, algae, and some bacteria capture energy from sunlight and use it to produce food (sugars) from carbon dioxide and water. During photosynthesis, oxygen is also released as a by-product. Examples of photosynthetic organisms include plants, algae, and some bacteria.
Cellular respiration is the process by which cells break down food molecules to produce energy, which is then used to power the cell's activities. It involves the conversion of the chemical energy stored in carbohydrates, fats, and proteins into a form of energy that can be used for cellular activities. Examples of cellular respiration include glycolysis and the Krebs cycle.
Photosynthesis and cellular respiration are connected in that they are part of a cycle of energy exchange between plants and animals. During photosynthesis, plants use energy from the sun to convert carbon dioxide and water into oxygen and glucose.
During cellular respiration, animals use oxygen and glucose to produce energy and carbon dioxide. Plants and animals benefit each other in that plants use the carbon dioxide produced by animals to perform photosynthesis, and animals use the oxygen produced by plants for respiration. In this way, plants and animals form a mutually beneficial cycle of energy exchange.
Which colour change is observed in the leaf?
Depending on the strength of the light hitting it and the amount of light reflecting from it, the leaf will assume the color that it cannot absorb, which could be red or blue.
The leaves quickly changed color from green to yellow within a few days, proving that even in the middle of summer, tree leaves may transform from summer to fall hue when exposed to insufficient sunshine. 10–20% is eliminated, and the remaining amounts are absorbed.
Chlorophyll decomposes, the green color vanishes, and the yellow to orange hues emerge, contributing to the fall brilliance of the leaves. Red anthocyanin pigments evolve as a result of other chemical changes that could take place at the same time.

What is the net charge of an ion that has 9 protons 11 neutrons and 11 electrons
2-
Explanation:Net charge describes the overall negative or positive charge of an atom or compound. Also, note that it is common in chemistry to write the sign of the charge after the number. Nevertheless, the charges +1 and 1+ are completely the same.
Calculating Charge
To find the charge of an atom you should look at the number of protons and electrons. Since neutrons have a neutral charge, aka no charge, they do not factor into net charge. On the other hand, protons have a positive charge and electrons have a negative charge. Each proton has a 1+ charge and each electron has a 1- charge.
To find the net charge find the total charge of the electrons and the total charge of protons, then add them together. Since there are 9 protons, the total proton charge is 9+. There are 11 electrons, so the total electron charge is 11-. For the purposes of doing the math, we can move the sign to the front.
(+9) + (-11) = -2Thus, the net charge is 2-.
Anions and Cations
To work with ions it is important to understand the vocabulary surrounding ions. Firstly, negative ions, like the one described in the question, are called anions. You can remember this as "A Negative ION". Also, positive ions, ions with positive net charges, are called cations. You can remember that the "t" looks like a plus sign.
What are these chromosomes considered as heterozygous?
Heterozygous genotype is the one in which the individual has two different alleles.
Homozygous and heterozygous are the terminologies which are used to describe the allele pairs which are present in a particular organism. Organisms that happen to carry two identical alleles are known to have a homozygous genotype of that allele whereas those organisms which have different alleles are known as heterozygous.
For example, if the allele "W" codes for white fur in dogs and the allele "w" codes for brown fur in dog, then a heterozygous individual will have the genotype "Ww" and a homozygous individual will have the genotype "ww" or "WW".

Buffer
A strong base
Heterogeneous mixture
Enzyme
Solution X would be classified as a buffer. Option 1.
What is a buffer?A buffer solution is a solution whose pH does not change significantly with the addition of either a small amount of an acid or a base. The buffer solution in itself contains an aqueous solution of acid or base with a mixture of its conjugate base or acid respectively.
Due to the composition, the pHs of buffer solutions do not change a great deal with the addition of a small quantity of acid or a small quantity of base.
Thus, if 10 mL of an acid solution is added to an unknown solution X whose pH is 7.3 and the pH of solution X remains unchanged from 7.3, then solution X would be a buffer solution.

The cycle is named after Melvin Calvin, who was awarded the Nobel Prize in Chemistry in 1961 for his work on the cycle.
The last phase is called the "regeneration phase" or the "reductive phase" wherein the Calvin cycle regenerates the CO2 acceptor (RuBP) using the products of the previous stages, CO2 and NADPH, so that the cycle can continue.
