Answer:
Phototropism is the growth of an organism in response to a light stimulus. Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light contain a hormone called auxin that reacts when phototropism occurs.

When individuals experience fear and pleasure, what part of the brain has been stimulated?
The limbic system of the brain gets stimulated when an individual experiences fear and pleasure.
The limbic system is a part of our brain which is responsible for the regulation of our emotional and behavioral responses, especially the ones we need for our survival. The structures of the limbic system are embedded deep in the brain. The two major structures of the limbic system include the hippocampus and the amygdala. The hippocampus helps us associate emotions and senses with different memories. The amygdala plays a pivotal role in managing our strong emotions like aggression, fear and pleasure. It also helps us in making new memories.

There are too manh pottasium ions inside a cell.as a result, the cell membrane expands and bursts. which problem was the cell most likely having?
The problem which led to the bursting of the cell is osmosis. This is specifically due to endosmosis which occurs because the cell failed to maintain its internal environment and thus expands and bursts.
Potassium ions are essential for cellular metabolism. Potassium ions are necessary for regulation of membrane potential and polarization and depolarization of the cell membrane. If a cell has too much potassium ions, the inside of the cell becomes hypertonic, with respect to its surrounding. This destabilizes the internal environment and leads to water entering the cell(endosmosis). As endosmosis occurs the cell starts to expand due to excessive water. This leads to expansion and tears and cracks in the cell. The further expansion of the cell leads to the bursting of the cell or lysis of the cell.

In a population that is in Hardy-Weinberg equilibrium, 49% of the population show the homozygous recessive genotype. The frequency of homozygous dominant individuals is:
The frequency of homozygous dominant individuals is: 42%
Hardy–Weinberg equilibrium (HWE) is a null model of the relationship between allele and genotype frequencies, both within and between generations, assuming no mutation, no migration, no selection, random mating, and infinite population size. To find the frequency of the recessive allele, we must first find the frequency of the dominant allele (p). According to the Hardy-Weinberg principle, the square root of the homozygous genotype frequency is equal to the allele frequency. The Hardy-Weinberg equation used to determine genotype frequencies is: p2 + 2pq + q2 = 1. Where 'p2' represents the frequency of the homozygous dominant genotype (AA), '2pq' the frequency of the heterozygous genotype (Aa) and 'q2' the frequency of the homozygous recessive genotype (aa).
Calculation:
q2 = 49
q= 0.7
According to Hardy–Weinberg equilibrium p + q= 1
p = 1 - q
1-0.7= 0.3
p2+ 2pq+q2=1
One can substitute the values
2pq= 2(0.3) (0.7) = 0.42
42% is the answer.

process of DNA replication
DNA replication is the process through which cells make copies of the genome's DNA. A cell must first replicate its full genome before it can divide, ensuring that each daughter cell has a complete genome upon division.
What is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is crucial.The ability of each DNA strand to function as a template for duplication is essential to the replication process. DNA double helix unwinding occurs at specified locations, known as origins, where DNA replication begins.The production of a primer, a brief section of RNA that serves as the beginning point for synthesizing fresh DNA, follows. By matching nucleotides to those on the original strand, an enzyme known as DNA polymerase starts duplicating the DNA. Once synthesis is finished, the RNA primers are switched out for DNA, and any gaps between freshly produced DNA segments are closed by enzymes.Since DNA replication is a critical process, the freshly manufactured DNA is proofread by the cell to make sure no errors or mutations are added. Once a cell's DNA has been duplicated, it can divide into two identical copies, each of which has the original DNA.To learn more about DNA, refer to:

In addition to their distinctive subsistence strategies, horticulturalists are characterized by a large population and land ownership.
What are subsistence strategies?A subsistence pattern often called a subsistence strategy, is the way a civilization meets its fundamental necessities for survival. This includes having access to food, water, and shelter. Foraging, horticulture, pastoralism, agriculture, and industrial food production are the five basic groups of subsistence patterns.
The earliest kind of subsistence is foraging, which was the mainstay of all human cultures up until about 10,000 years ago. Horticultural societies often use basic tools for small-scale gardening. Higher population densities are possible using these strategies, but they still rely on the availability of lots of undeveloped lands.

Which condition is a heightened response that occurs after exposure to a noxious stimulus?
Hyperalgesia is a heightened response that occurs after exposure to a noxious stimulus.
Hyperalgesia:An increased sensitivity to feeling pain and extreme response to pain. When the nerves or the chemical makeup of the nerve pathways involved in pain perception are damaged, hyperalgesia may result. Your body's particular nerve receptors are becoming more sensitive, which is the reason for this. As a result of a surgery or procedure, tissue or nerve injury may result in hyperalgesia. Additionally, it can happen to persons who are using opioids.
A noxious stimulus is one that is potent enough to endanger the integrity of the body (i.e. cause damage to tissue).

Zebras and other grazers band together when grazing. which type of behavior is this?
The behavior of zebras and other grazers banding together while grazing indicates their social behavior to protect themselves and their group mates from predators.
Grazing: It is a process in which herbivores roam from one place to another in search of grass, small plants, etc which are the main source of food for them. It involves forage search, selection of forage, and eating the selected forage. Different animals differ in the type and method of searching and eating forage. This different grazing behavior makes them different from one another.
Although, one common thing which is observed in these grazing animals is the practice of grazing in bands or groups. This is generally noticed in the area where they have more danger from predators so they practice this banding method as a protective measure because predators find it difficult to attack groups and they get less chance to kill a lone individual.
