Seeds perform various functions for the plants that generate them, among them the essential function is dispersal to a new location, nourishment of the embryo, and dormancy at the time of inappropriate conditions.
Seed coat is the part of the seed that protects the seed from temperature-associated, physical, or water destruction, it helps in the protection of developing embryo, and it is the seed coat, which makes sure that the plant seed remains in a dormant state until the circumstances become ideal for the plant embryo to sprout or germinate.
Hi
<span>Firstly, the white blood cells tend to have a higher surface to volume ratio then other cells because the are more amorphous. That would lead to an relative increase in plasma membrane, which contains receptors for identifying antigens. Thats why, the white blood cells may be more receptive to detection of antigens due to a higher surface-to-volume ration. It's basically because this.</span>
Answer:
they can conclude that they was not as extinct as you think they was.
Explanation:
in my opinion if im wrong tell me.
The answer is F, false. Natural selection is still involved, with stronger and more procreative individuals spreading their genes. An example of when natural selection is not involved would be when human breeders look for specific traits and breed accordingly.
Answer:
Elements that are found in the same horizontal row (belong to the same period) in the periodic table, e.g. Fluorine and Neon both have the same energy level of 2.
<em>Note: The question does not specify any two elements.</em>
Explanation:
The modern periodic table is organized into eight vertical columns known as groups and seven horizontal rows known as periods. The atomic number ( number of protons in the nucleus) of elements increases when moving across the periodic table from left to right. The horizontal rows or periods represents an energy levels or the number of electron shells in an element. Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. Elements belonging to the same period have the same number of energy level or shells. For example, the elements belonging to Period 2 include lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. These all have the same number of energy level of 2.
