Answer:
Females and males each have some amount of the sex hormones, androgens and estrogens. In males however, androgens like testosterone is more dominant and in females estrogens like estradiol are more dominant. The hormones both affect the sexual response cycle. The sexual response cycle has four phases: desire, arousal, orgasm and resolution. The desire phase can last anywhere from a few minutes to hours and includes physical changes like an increase in muscle tension, heartbeats quickening, flushed skin, and an increased flow of blood to genitals. The arousal phase extends to the brink of the orgasm phase, during this phase the changes experienced in the desire phase are intensified along with blood pressure increasing. The orgasm phase generally only lasts a few seconds and is the climax of the sexual response cycle, some characteristics include: Involuntary muscle contractions and spasms, blood pressure, breathing, and heart rate at their highest point, a release of built up sexual tension, and flushed skin. During the resolution phase the body returns to normal, often a sense of wellbeing and fatigue is achieved. To begin the cycle a male need a certain amount of the androgen, testosterone, but high levels in females tend to lead to more sexual thought and desires, typically though, women have relatively low levels of testosterone. In women, estrogens, such as estradiol are more common. Estrogens are produced when a girl starts puberty and helps her reproductive cycle begin. A high level of estrogen in men can lead to a reduced sex drive, loss of hair, or trouble focusing, but a normal level in men is crucial to proper erectile function.

what is brain cancer ?
Answer:
Brain cancer is an overgrowth of cells in your brain that forms masses called tumors. Cancerous, or malignant, brain tumors tend to grow very quickly. The symptoms of brain cancer depend on the size and location of the tumor.
Common brain cancer symptoms include:
headaches that are usually worse in the morning
nausea
vomiting
a lack of coordination
a lack of balance
difficulty walking
memory lapses
difficulty thinking ,speech problems
.Many of the symptoms of brain cancer are also caused by other, less serious conditions. There’s no need to panic if you’re experiencing these symptoms, but it’s a good idea to visit your doctor to have your symptoms investigated, just in case.
Explanation:
The recombination frequency between linked genes A and B is 40%, between B and C is 20%, between C and D is 10%, between C and A is 20%, and between D and B is 10%. What is the sequence of the genes on the chromosome?
Answer:
ACDB (or BDCA)
Explanation:
The linked genes A and B have a greater frequency of recombination (40%) and therefore they are found furthest away on the chromosome. Conversely, the smaller distance is between D and B, which exhibit a lower frequency of recombination (10%), while C is localized at the same physical distance of both A and B (20%), so the physical map is ACDB.
Physical map:
A--------C-----D-----B

How can point and frameshift mutations contribute to biodiversity of Earth? Explain your
answer.
Answer:
These mutations form new alleles that increase genetic variation in a population. This variation may lead to new species which increases biodiversity.
Explanation:
Mutations are randomly occurring modifications that exist within the genetic code, leading to replication errors in DNA. DNA molecules are long-chain, helical macromolecules that store genetic material. They consist of different monomer sequences called nucleotides. In a reading frame, which contains instructions for protein production, they shape base pairs and codon sequences.
Single nucleotide polymorphisms are normal, as silent mutations, which sometimes result in no changes in amino acids. Some mistakes add a random nucleotide (SNP) in point mutations resulting in new alleles.
Frameshift mutations occur from nucleotide insertions or deletions that are not divisible by 3. This results in the codon requiring more or fewer nucleotides which disrupt the reading frame, resulting in a separate protein translation.

what is the relationship between exposing to a virus and developing immunity to it? cite evidence from the text to support your response
Answer:
Exposure to a virus is closely related to the development of immunity, since the immune system is responsible for creating antibodies in response to the presence of potentially harmful biological agents, such as these viruses.
Explanation:
Viruses are biological agents that can produce diseases when they enter the body of a living being. In response to contact with a virus, the immune system synthesizes specific antibodies to combat the foreign biological agent.
Antibody immunity can be of two types. It is fast when it is mediated by immunoglobulins M (IgM), which attack the virus anywhere, while the late and prolonged response is due to the development of immunoglobulins G (IgG).
An example of immunity to a virus occurs with the exhibition to the virus of the Dengue, that creates permanent immunity to the viral serotype to which an individual is exposed.
The acquired immunity, mediated by antibodies, is the base for the development of vaccines.

ATP is a(1 point)
storable form of energy.
usable form of energy.
form of energy that can be used and stored.
form of energy that can be stored and released as heat.
Hello there!
Your answer should be ATP is a stored form of energy.
You see, Think of it as the “energy currency” of the cell. If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell. Hope this works!
Answer:
a storable form of energy

Answer:
It helps you understand how life forms and what it takes for life to develop as well as the changes through this life cycle
Explanation:
Knowing information about embryo development is important because it helps us to understand how an organism grows and develops from a single cell into a complex being.
Why knowledge about embryo development important?An embryo is the stage of development that follows fertilization and begins when the zygote, a single cell formed by the union of a sperm and egg, begins to divide and differentiate into the various cell types that will make up the organism.
This knowledge can be used in various fields, such as reproductive medicine, to help improve fertility treatments and increase the chances of successful pregnancies. It can also be used in fields such as genetics and evolutionary biology to understand how traits are inherited and how species have evolved over time. Understanding embryo development can also provide insights into the causes of birth defects and developmental disorders, and help researchers develop treatments or interventions to improve the health and well-being of individuals.

Two parrots have different parents. One parrot has red chest feathers, and the other parrot has yellow chest feathers. Why do the parrots have different feather colors on their chest?
Answer:
Hereditary traits.
Explanation:
Since these two parrots (with two different parents), one with yellow feathers and the other one red, it would make sense that they inherited their traits from their parents.
Just as humans have different colors of hair. Parrots can have different chest colors. Both of these come from hereditary genes.
