The Moon is the natural satellite of Earth. Its revolution lasts 27.322 days, while its rotation around its axis lasts 27 days. From the Earth's perspective, the Moon seems to have different phases, where it appears as fully lighted, partially lighted, or totally dark. What the Moon appears to be from the Earth depends on how the Earth, Moon, and Sun are aligned in relation to each other. If the Earth is between the Sun and the Moon, the Moon is full, with the reason being that the Sun is lighting up the side that is facing the Earth. If the Moon is between the Earth and Sun, then the Moon can not be seen, it is totally dark, and that is because the side that is facing the Earth is not lighted by the Sun at all. If the Moon is positioned sideways, not being in a straight line with the Earth and Sun, then it appears to be partially lighted, and that is the side that can be seen from Earth that is lighted by the Sun.
Based totally on the ear, the Recommended Dietary Allowance (RDA) represents an amount that meets the desires of ninety-seven to the ninety-eight percentage of healthy people in an age/gender institution.
ok consumption (AI): hooked up while evidence is insufficient to increase an RDA and is ready at a degree assumed to make certain nutritional adequacy.
Consumption of irradiated food during pregnancy can cause birth defects is false.
<h3>What are birth defects?</h3>
Birth defect in pregnancy are the structural or functional abnormalities occur during intrauterine stage. It can be detected either prenatally or in infancy state.
The primary causes are genetic, Socioeconomic, Environmental and other factors.
Chromosomal abnormalities and single gene defects are the major genetic abnormality based birth defects, such as Down syndrome and cystic fibrosis etc.
When parents are related by their blood group can also leads to high risk of rare genetic birth defects.
Hence, the statement is false

The statement that is correct about plasma membranes is that both plant cells and animal cells have flexible plasma membranes (option C).
<h3>What is the plasma membrane?</h3>
Plasma membrane is the semipermeable membrane that surrounds the cytoplasm of a cell. The semi-permeability of the plasma membrane means it allows some molecules through but blocks other substances.
The plasma membrane is the cellular structure that protects and encompasses the cell's content.
All living organisms possess the plasma membrane, which is also called cell membrane.
Therefore, the statement that is correct about plasma membranes is that both plant cells and animal cells have flexible plasma membranes.

Answer:
A. dihybrid crosses
Explanation:
A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.
