Answer:
Mendel's Laws of Heredity are usually stated as:
1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells so that sex cells contain only one gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.
2) The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.
3) The Law of Dominance: An organism with alternate forms of a gene will express the form that is dominant.
Explanation:The genetic experiments Mendel did with pea plants took him eight years (1856-1863) and he published his results in 1865. During this time, Mendel grew over 10,000 pea plants, keeping track of progeny number and type. Mendel's work and his Laws of Inheritance were not appreciated in his time. It wasn't until 1900, after the rediscovery of his Laws, that his experimental results were understood.

Very large, massive stars burn their fuel much ___________ than smaller stars.
Answer:
Very large, massive stars burn their fuel much faster than smaller stars. Their main sequence may last only a few hundred thousand years. Smaller stars will live on for billions of years because they burn their fuel much more slowly. Eventually, the star's fuel will begin to run out.

(d) State the importance of mitosis in the growth of a multicellular organism, such
as a
flowering plant or a mammal.
Explanation:
Like other multicellular organisms, plants grow through a combination of cell growth and cell division. Cell growth increases cell size, while cell division (mitosis) increases the number of cells. As plant cells grow, they also become specialized into different cell types through cellular differentiation.
Generation Number of purple flowers Number of white flowers 1 705 224 2 792 189 3 834 102 4 889 84 5 938 21 6 952 0 Ralph wanted to breed a pea plant that produced only purple flowers. He continued to breed purple-flower producing pea plants together over six generations. The results of Ralph's artificial selection are shown above. What did artificial selection do to the population of pea plants? A. caused a new species of pea plant to form B. increased its genetic diversity C. decreased its genetic diversity D. caused a pea plant to exhibit a new characteristic
Answer:
C
Explanation:
The correct answer would be that artificial selection decreased the genetic diversity of the pea plant.
Genetic diversity is a measure of the number of traits or characters.
Initially, the breeding produced a considerable population of both white and purple flower offspring. But as time goes on, the population of purple flower offspring increased while that of the white flower decreased till it eventually reached zero.
Thus, artificial breeding reduced the number of traits in the population of the offspring from two to one - a case of reduction in genetic diversity.

Nitrogen-fixing bacteria making
nitrogen available for use by other
organisms to utilize is an example
of..
A. mutualism.
B. commensalism.
C. decomposition
The nitrogen fixation bacteria makes the nitrogen available for the plants directly into the soil. This is an example of mutualism, where both bacteria and organisms are benefited.
Most leguminous plants like peas, bans, and cloves have colonies of nitrogen fixation bacteria. These bacteria are found attached to the roots nodules and tend to fix the nitrogen. Through this, the bacteria gain sugar from the plant.Hence mutualism is the end product of the interaction. This option A is correct.

Answer:
Aerobic: Processes Oxygen, Carbon Dioxide by-product
Anaerobic: Processes Carbon Dioxide, Fermentation
Both: Produces ATP, Takes place in cells
Explanation:
Aerobic Process: Oxygen, Carbon Dioxide by-product
Anaerobic Process: Carbon Dioxide, Fermentation
Both: Produces ATP, Takes place in cells
What is respiration ?Respiration is a metabolic process in which an organism's living cells use oxygen to obtain energy (in the form of ATP) and release carbon dioxide as a byproduct of the oxidation of complex organic substances.
Anaerobic respiration occurs when there is no oxygen present, whereas aerobic respiration occurs when there is oxygen. Alcohol is produced by anaerobic respiration, whereas carbon dioxide and water are the byproducts of aerobic respiration. Compared to anaerobic respiration, aerobic respiration produces more energy.
Thus, respiration is a vital process of the body.

What is the importance of the amniotic egg?
Answer:
The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. But thanks to the amniotic egg, reptiles can lay their eggs nearly anywhere on dry land.

Would a cell that did not undergo cytokinesis be able to function properly? Explain.
Answer:
If cytokinesis wouldn't really occur, the cytoplasm would not be broken and two similar daughter cells would not function as a result. Therefore a cell should not be divided into two separate cells to stay at rest.
Explanation:
Cytokinesis, which is the final step of mitosis, is split into two isolated, equivalent daughter-cells by the material.

Shortly after ingesting a big plate of carbohydrate-rich pasta, you measure your blood's hormone levels. What results would you expect, compared to before the meal
Answer:
blood hormone level will increase
Explanation:
since once food reach the stomach it will trigger different hormone process that cause release of enzymes required to digest carbohydrate
After ingesting a plate of pasta, which is rich in carbohydrates, the levels of insulin increases and glucagon decreases in the blood.
The working of insulin and glucagon:The hormone insulin and glucagon work in a negative feedback loop. At the time of digestion, the foods, which comprise carbohydrates are transformed into glucose. The majority of this glucose is sent to the bloodstream, resulting the elevation of blood glucose levels.
This enhancement in the levels of glucose in the blood signals the pancreas to generate insulin, and reduce the levels of glucagon in the blood. After some hours, glucagon works to counterbalance the activities of insulin.
After five to six hours, the levels of glucose in the blood decreases due to the activity of insulin, this instigates the pancreas to generate glucagon.
Thus, after eating carbohydrate rich food, the levels of insulin increases in the blood and glucagon decreases.
