Answer:
The correct answer is stated in the Explanation section.
Explanation:
Santhi Soundarajan is an Indian track and field athlete that have won multiple international medals. Santhi was the center of a controversy when she was striped her silver medal after failing a sex verification test at the 2006 Asian Games. Santhi has a condition known as androgen insensitivity syndrome, she carries a Y chromosome althoug she has female genitalia. I think is not fair to disqualify an athlete like Santhi unless it is determined that she committed fraud and that she has an evident advantage. If Santhi knew her condition and it is established that she has an advantage after multiple tests, then her medal could be removed.

The worlds population won't stop growing till something bad in the wrold happens like a war or the fertility rates drop to an all time low.For example if a lot of people are out at a war the frertility rates are going to be low and the death rates will be high.Therefore the population will stop growing and will decrease or stay the same.
A yellow cat is crossed with a black cat. You know that the black and yellow fur color traits are carried on the X chromosome and only one X chromosome is expressed in a cell. You observe that half the offspring are calico (patches of black and yellow) and half are black. Your friend Tien tells you that the black cat was the mother, the yellow cat was the father, and all the calico kittens are females. Is he correct? Write out all the possible crosses to test his answer.
Answer:
Tien is correct with his answer that all the calico kittens are females.
The reason and the possible crosses to test the answer are given below
Explanation:
First of all, the coat color in cats is hugely decided by the sex-linked X chromosome in the female. This X chromosome found in cats makes cats exhibit codominant traits. The calico cat is a blend of black and yellow patches. To be considered calico, a cat must carry an allele for the black color and an allele for the yellow color.
The male is no heterozygotes and since the Y- chromosome in the male doesn't affect the result of the coat color in the offspring, there has to be a rare genetic disorder that will result in a calico kitten that is male.
The possible crosses to test his answer:
Cross 1:
If the black cat was the mother her genotype would be: Xb Xb
If the yellow cat was the father his genotype would be: Xy Y
The possible offspring from the cross would result in:
XbXy XbY XbY XbXy ( where XbXy are calico females and XbY are black males)
Cross 2:
If the yellow cat was the mother her genotype would be: Xy Xy
If the black cat was the father his genotype would be: Xb Y
The possible offspring from the cross would result in:
XyXb XyY XyXb XyY (where XbXy are calico females and XyY are the yellow males)

O Carbon Cycle
Nutrient cycle is also known as the cycle of matter. Nitrogen, water and carbon all three are cycle of matter but energy cycle is not. Thus, correct option is B.
What is Nutrient Cycle?
Cycle of matter are also known as Biogeochemical cycles. These cycle include both biotic and abiotic factors. Cycle of matter are described into five types based on matter: a. water cycle, b. nitrogen cycle, c. phosphorus cycle, d. sulfur cycle, e. carbon cycle.
Matter constantly moves in the cycle involving change in the state. The matter cycles are essential as they recycle important nutrients required for the survival of living organisms.
In contrast to this, energy flows in the atmosphere. It is the interaction between the energy sources within Earth. The interaction between energy sources and Earth's atmosphere is very significant and a small change could lead to significant change in climate behavior of an area.
Therefore, the correct option is B. Energy cycle is not a cycle of matter.

What human body response help maintain homeostasis?
Answer:
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted.
Explanation:
Answer:
If a raise in body temperature (stimulus) is detected (receptor), a signal will cause the brain to maintain homeostasis (response). Once the body temperature returns to normal, negative feedback will cause the response to end. This sequence of stimulus-receptor-signal-response is used throughout the body to maintain homeostasis.
Explanation:
Enzymes are proteins that have a three dimensional shape that is specific to a particular substract. environmental conditions can change. the shape of protein
Answer:
The enzyme will no longer be able to catalyze the reaction with the substrate
Explanation:
Enzymes usually have a very specific structure than holds the substrate molecules, facilitating the optimal environment for the reaction to proceed. This reduces the activation energy required to start the reaction.
If the shape changes, the substrate molecule will no longer properly fit. Therefore, the enzyme will not be able to catalyze the reaction.
Describe how skin pigmentation is determined, and also
how it is affected by exposure to the sun.
Answer:
pigmentation is determined by the amount of melanin in the skin. Without melanin, the skin would be pale white with shades of pink caused by blood flow through the skin. The extra melanin makes your skin look darker or sun-tanned. In some cases, the sun causes an uneven increase in melanin production, which produces irregular coloring of the skin. The sun can also cause a permanent stretching of small blood vessels, giving your skin a mottled, reddish appearance.

Which statement is FALSE? First exclude the four that are correct. While performing photosynthesis during the day, the chloroplasts of a green leaf produce Which statement is FALSE? First exclude the four that are correct. While performing photosynthesis during the day, the chloroplasts of a green leaf produce ATP to be used in the Calvin cycle. ATP as an energy source for the roots of the plant. sugars for the green leaf’s cellular respiration at night. sugars as an energy source for the roots of the plant. sugars to fuel the growth of the plant.
Answer:ATP as an energy source for the roots of the plant.
Explanation:
Photosynthesis is the process by which plants manufacture their own food. It involves the combination of water and carbon dioxide in the presence of sunlight. Sugars are produced in the process.
The ATP molecules produced during photosynthesis are not transported to plant root cells. Rather, metabolic activities within the plant root cells produces the energy molecules required by the plant roots.

In what order do the electrons move through the electron transport chain?
Answer:
Four Stages: Glycolysis (a transition reaction that forms acetyl coenzyme) A, the citric acid (Krebs) cycle electron transport chain, and chemiosmosis.
Explanation:
The flow of electrons through the components of the electron transport chain occurs in order of increasing reduction potential.
Electronic transport chain is the set of enzymatic complexes embedded in the mitochondrial membrane that oxidize NADH and FADH2, generating a proton gradient.
It basically comprises 2 processes:.
1) Electrons are transported across the membrane, from one carrier protein complex to another.
2) Protons are translocated through the membrane, which means that they are passed from the interior or mitochondrial matrix to the intermembrane space causing a proton gradient.
Oxygen is the final acceptor of the electron, combining with them and the H ion to produce water.
This chain comprises numerous associated components in the form of enzyme complexes, each of which has transmembrane proteins that support the complex on the inner mitochondrial membrane, an Fe-S flavoprotein, ubiquinone, and the cytochrome chain.
The electrons start out in order with very high energy, which they lose as they pass through the chain. In other words, the carrier molecules are reduced and oxidized, lowering electrons from high energy levels to lower ones.
Therefore, we can conclude that the flow of electrons through the components of the electron transport chain is carried out in order from high energy levels to lower ones.
