In the stem of a plant that is bending toward the light, auxins are most concentrated in the side of the stem away from the light.
What is auxins?Auxins are a class of plant hormones that are involved in many aspects of plant growth and development, including phototropism, which is the ability of a plant to bend and grow toward a light source. When a plant is exposed to light from one direction, auxins migrate from the light side of the stem to the shaded side, causing the cells on the shaded side to elongate more rapidly than the cells on the light side. This differential growth results in the bending of the stem toward the light. The concentration of auxins is highest on the shaded side of the stem, where they accumulate due to their movement away from the light. Therefore, in the stem of a plant that is bending toward the light, auxins are most concentrated in the side of the stem away from the light.

chin fissure is controlled by a dominant allele and a smooth chin by a recessive allele. dimples are controlled by a dominant allele and no dimples by a recessive allele. if two parents are heterozygous for each trait, the chance that they will produce a child with a chin fissure and dimples is .
The question is: "If two parents are heterozygous for each trait, the chance that they will produce a child with a chin fissure and dimples is?"
The answer is 25%. When two parents are heterozygous for a trait, they each carry one dominant allele and one recessive allele. This means that the chance of producing offspring with a chin fissure and dimples is 25% since these traits are both controlled by dominant alleles. This is because out of the four possible combinations of alleles that can result from two heterozygous parents, only one combination results in both traits being expressed (dominant allele for chin fissure + dominant allele for dimples).
The chance that two heterozygous parents will produce a child with a chin fissure and dimples are 3/16.
What is the meaning of allele?
An allele refers to any of the alternative forms of a gene that may exist at a particular locus. More specifically, an allele is one of two or more variants of a gene that have been shown to arise from mutations and are found at the same position on a chromosome. To explain the chance that two heterozygous parents will produce a child with a chin fissure and dimples is 3/16, first, we must know that heterozygous means when two different alleles are present. Now, let's solve the problem. At first, write down the genotypes of the parents:
C = chin fissure
c = smooth chin
D = dimples
d = no dimples.
So, the parents are heterozygous, which means that their genotypes are CcDd.Next, create a Punnett square to determine the possible offspring genotypes. According to the Punnett square, the offspring can have four different genotype combinations: CCDd, CCdd, CcDd, and Ccdd. The probability that a child will have a chin fissure is 3/4, and the probability that a child will have dimples is 3/4 as well. So, the probability that a child will have both traits is:(3/4) * (3/4) = 9/16The probability of all other combinations is:(3/4) * (1/4) * 2 + (1/4) * (3/4) * 2 + (1/4) * (1/4) = 3/16Therefore, the chance that two heterozygous parents will produce a child with a chin fissure and dimples are 3/16.

how do salty-tissue freshwater fish survive in fresh water? what type of regulators are freshwater fish?
Salty-tissue freshwater fish are able to survive in freshwater due to their osmoregulatory abilities. Osmoregulation is the process by which organisms maintain their internal osmotic balance, allowing them to adapt to different salinity levels.
Salty-tissue freshwater fish survive in freshwater by regulating their osmotic pressure. This is done by the active uptake of salt from the environment, the excretion of water, and the conservation of solutes that are essential to their normal physiology.
Freshwater fish, on the other hand, regulate their body fluids through the uptake of water and the excretion of solutes. The majority of freshwater fish are hypoosmotic, which means they live in an environment with a lower salt concentration than their internal fluids. As a result, they must constantly expel excess water and absorb minerals from the water to avoid becoming overly diluted.
Furthermore, they must continuously excrete dissolved nitrogenous wastes, which can be toxic to them if they accumulate. The kidneys of freshwater fish are more effective at excreting excess water than those of marine fish. The nephrons in freshwater fish have fewer convoluted tubules and lack specialized ion-absorbing cells, whereas the opposite is true for saltwater fish.
Regulation of the osmotic pressure of the environment in which they live is essential for the survival of fish. The systems that regulate the osmotic pressure of the environment are known as osmoregulatory systems.

In addition to epinephrine, your body also releases a steroid that responds to stress. Epinephrine wears off quickly, but the steroid, corticosterone, can last hours. Where we would predict that corticosterone (the signaling molecule) would bind to its receptor? Group of answer choices plasma membrane receptor protein nucleus
Corticosterone is a steroid hormone that is released by the adrenal gland in response to stress.
Unlike epinephrine, which binds to plasma membrane receptors and triggers a rapid response, corticosterone binds to intracellular receptors located inside the cell. Specifically, corticosterone binds to receptors in the cytoplasm of target cells, which then translocate to the nucleus to regulate gene expression. This results in changes in protein synthesis that can last for hours, allowing the body to mount a sustained response to stress. Overall, corticosterone's mechanism of action is slower and more long-lasting than epinephrine's, reflecting the different physiological roles of these two hormones in the stress response.
