Within a cell, DNA is housed in the nucleus (in eukaryotic cells) or in the nucleoid region (in prokaryotic cells).
What is DNA?DNA (Deoxyribonucleic acid) is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all living organisms and many viruses. It is a long, double-stranded helical molecule composed of nucleotides, which are the basic building blocks of DNA.
Each nucleotide consists of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, or thymine). The sequence of these bases determines the genetic code carried by the DNA molecule.
Thus, the DNA is housed in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells.

the impact of extinction to the environment
Answer:
Changing systems are inevitable but likewise bring harsh and even uncontrollable effectsExtinction is especially harmful because of the concept of mutual or coexistence theorems in which certain animals depend on others We will examine the food chain: Say that grasshoppers go extinct and the lizards that eat them exclusively now have no food source. That effect transcends into a higher order as it climbs up the food ladder. Effectively these said lizards could have been controlling the bug population and effectively the grasshoppers controlled smaller micro organisms which now are left to their own devices given the extinction of the grasshoppers.effectively those microorganism can damage ecosystems and dramatically change the composition or animals and vegetation that exist in said area.Answer:
1) it'll affect the chain reactions in the whole ecosystem and therefore, have a big effect on the environment.
2) if this happens then humans may lose the source of medicines as well, thus humans will be hit by a disease and there would probably be no cure, hence again affecting the biodiversity.

The endocrine system regulates the body through hormone release. Like the nervous system, what does the endocrine system help maintain?
A. homeostasis
B. reflexes
C. chemicals
D. neurons
Answer:
How is the endocrine system related to the nervous system in terms of its regulatory activity?
For one, the endocrine system uses chemical signaling (hormones, produced by glands) while the nervous system uses electrical signaling (neural impulses). The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are more short-lived.

Exoskeleton
A true exoskeleton, like that found in arthropods, must be shed (moulted) when it is outgrown. ... The new exoskeleton is still capable of growing to some degree, however. Animals of the order arthropoda, like lizards, amphibians, and many other animals that shed their skin, are indeterminate growers

Explain how and why the walls of the ventricles differ in thickness.
and between
Answer:
The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria. ... This is due to the higher forces needed to pump blood through the systemic circuit (around the body) compared to the pulmonary circuit.

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones.
Alternative names for thyroxine
T4; tetraiodothyronine; thyroxin
What is thyroxine?
Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It is the inactive form and most of it is converted to an active form called triiodothyronine by organs such as the liver and kidneys. Thyroid hormones play vital roles in regulating the body’s metabolic rate, heart and digestive functions, muscle control, brain development and maintenance of bones.
How is thyroxine controlled?
The production and release of thyroid hormones, thyroxine and triiodothyronine, is controlled by a feedback loop system that involves the hypothalamus in the brain and the pituitary and thyroid glands. The hypothalamus secretes thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormone. This hormone stimulates the production of the thyroid hormones, thyroxine and triiodothyronine, by the thyroid gland.
This hormone production system is regulated by a feedback loop so that when the levels of the thyroid hormones (thyroxine and triiodothyronine) increase, they prevent the release of both thyrotropin-releasing hormone and thyroid stimulating hormone. This system allows the body to maintain a constant level of thyroid hormones in the body.
What happens if I have too much thyroxine?
The release of too much thyroxine in the bloodstream is known as thyrotoxicosis. This may be caused by overactivity of the thyroid gland (hyperthyroidism), as in Graves' disease, inflammation of the thyroid or a benign tumour. Thyrotoxicosis can be recognised by a goitre, which is a swelling of the neck due to enlargement of the thyroid gland. Other symptoms of thyrotoxicosis include intolerance to heat, weight loss, increased appetite, increased bowel movements, irregular menstrual cycle, rapid or irregular heartbeat, palpitations, tiredness, irritability, tremor, hair

If a woman is heterozygous for dimples and has 5 fingers, and a male is ... a Punnett square and calculate genotype and phenotype frequencies to explain your answer.
People also ask
According to the Mendel's Law of Segregation. Since, a male and a female, both with dimples, have a son without dimples which mean both the parents are heterozygous (Aa). since both are Aa × Aa there will be Aa, Aa, AA, aa. in which AA is dominant and aa is recessive thus the chance that a daughter of these parents would have dimple is 3/4.
What is Mendel's law of segregation?
Mendel's Law of Segregation states that a diploid organism passes a randomly selected allele for a trait to its offspring, such that the offspring receives one allele from each parent.
Thus, the chance that a daughter of these parents would have dimple is 3/4.

: Was the increase in the average beak depth caused by an increase in large-beaked finches or a decline in small-beaked finches?
Answer:
The increase in the average beak depth caused by both an increase in large-beaked finches and by a decline in small-beaked finches
Explanation:
The increase in the average beak depth is caused by both an increase in large-beaked finches and by a decline in small-beaked finches. All the small-beaked finches got disappeared. As a result, only large-beaked finches were left. The drought decreased the number of seeds such that large-beaked finches could eat the larger seeds to survive.

The organic compound below consists of an adenine molecule (blue), a ribose (purple), and three phosphate groups (orange). A compound has an adenine molecule, a ribose molecule, and 3 phosphate groups. Which compound is shown? chlorophyll ferredoxin ATP NADPH
Answer:
ATP
Explanation:
Adenosine Triphosphate (ATP) is an organic compound composed of an adenine nucleotide base attached to a ribose sugar and three (3) phosphate groups bonded to one another by high-energy (phosphoanhydride) bonds. In the ATP molecule, the ribose sugar is attached to a phosphate group. ATP is known as the energy unit of the cell because the energy released by the hydrolysis of phosphoanhydride bonds can be used to drive unfavorable reactions. ATP is also involved in intracellular signaling pathways by acting as a substrate for kinase proteins that transfer phosphate groups during phosphorylation.

Answer:
When there is a limited supply of water or food, organisms must compete for these resources in order to survive. Some will get to eat/drink but some others might not. As a result those organisms may die from lack of food/water, therefore decreasing the size of the population.
