The presence of over 700 genes involved in height determination is an example of a polygenic trait.
What is a polygenic trait?A polygenic trait refers to a trait that is determined by multiple genes rather than by only one gene. This is opposite to a monogenic trait that is determined by only one gene.

You are a biologist looking at samples of pond water. Using a microscope to investigate your samples, you identify a cell with a nucleus. Briefly explain how you know immediately that this is not a prokaryote. Additionally, without further investigation, would you be able to determine if it was a plant or an animal cell?
Answer:
You know it's not a prokaryote, because prokaryotes do not have a nucleus. You would not be able to determine if it was a plant or animal cell without further investigation because both have a nucleus.
Plant cells do have organelles that animals cells don't such as chloroplasts and cell walls, but you would have to investigate further.
The cell is eukaryotic one as it does not possesses a nucleus. For determining that the cell is of plants or of animals, the best way is to look at the criteria like cell wall, vacuoles, etc., which are present only in plant cells.
What is eukaryotic cell?Eukaryotes are organisms with nuclei in their cells. Eukaryotes include all animals, plants, fungi, and many unicellular organisms.
They are members of the Eukaryota group of organisms, which is one of the three domains of life. The other two domains are Bacteria and Archaea.
Plant cells have both a cell wall and a cell membrane. The cell wall surrounds the cell membrane in plants.
This is what gives plant cells their distinctive rectangular shape. Animal cells have only a cell membrane and no cell wall.
A cell wall, chloroplast, plasmodesmata, plastids, and various organelles are all found in plants.
Animal cells do not have cell walls, but they do have organelles such as tight junctions and cilia. The meristematic system, which is located at the tips of roots and stems, is responsible for plant growth.
Thus, this way, one can identify with further investigations that if it was a plant or an animal cell.

First of all, this pedigree is an x-linked dominant pedigree.
The dad has a genotype of [tex]X^{A}Y[/tex] (or whatever letter you choose to represent it) and since the mom is unaffected, she will be homo_zygous recessive or [tex]X^{a} X^{a}[/tex]. All the girls will receive the recessive allele from mom but the dad on the other hand can only pass on a dominant allele therefore all of the girls will become hetero_zygous with a genotype of [tex]X^{A} X^{a}[/tex].

Answer:
C. Out of the leaf by diffusion.
Explanation:
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. The solvent moves to dilute the concentrated solution and equalize the concentration on both sides of the membrane.
Examples of Osmosis: Examples include red blood cells swelling up when exposed to freshwater and plant root hairs taking up water. To see an easy demonstration of osmosis, soak gummy candies in water. The gel of the candies acts as a semipermeable membrane.
Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Examples of Diffusion: Examples of diffusion include the scent of perfume filling a whole room and the movement of small molecules across a cell membrane. One of the simplest demonstrations of diffusion is adding a drop of food coloring to water. Although other transport processes do occur, diffusion is the key player.
Based on the above information, your answer is most likely

All of the above Please select the best answer from the choices provided A B C D.
All of the options are applicable to organic farming.
Organic farmingOrganic farming is a form of farming that relies on natural processes for producing crops and livestock.
Thus, organic farmers avoid using synthetic products such as pesticides and agrochemicals on their farms. This makes them rely on the natural state of soils for crop production.
The natural health of the soil, however, depends on the interaction between organic matters and soil microbes to produce nutrients for the soil.

Why does our heart need two parts that are completely separate from one another?
Answer:
the heart is separated into two sides so that it can carry out its function well. The right heart contains deoxygenated blood and the left heart with oxygenated blood. the two sides are separated from each other so that the blood from the two sides don't get mixed. this leads to effective oxygenation of the deoxygenated blood in the right heart through pulmonary circulation and effective oxygenation of the tissues in the different parts of the body by the oxygenated blood of the left heart through systemic circulation.

Prothrombin is a plasma protein that is involved in the clotting process of blood. Its normal concentration in plasma is 30mg/200ml. What percent of the plasma is prothrombin?.
Given what we know, we can confirm that Prothrombin circulates through the blood at a percentage of about 15%.
How do we reach this percentage value?In order to reach this value, analysis of blood samples have shown the exact amounts that circulate per every set amount of blood, we can then divide these values in order to get a decimal value for the percentage, which after converting leads us to the answer of about 15%.
Therefore, we can confirm that Prothrombin circulates through the blood at a percentage of about 15%.
