All living things need to have cells before they are said to be living. this is because the cell is the basic unit of life.
Answer:
Reciprocal cross may be defined as the cross done by reversing the parent genotype. The reciprocal cross was performed by Mendel's during the pea plant experiment.
Mendel's reciprocal cross is important as it determines the contribution of the male or female in the particular trait. He reversed the male and female trait, cross them, whether the male or female is responsible for the transmission of the trait. He found that the progeny of the reciprocal cross are similar as the normal cross. Thus, he concluded that both the parents contribute equally in the transmission of trait.
Neutral atoms….? I think this is correct
Answer: ionic, covalent, and metallic
Explanation:
There are three major types of chemical bonds: ionic, covalent, and metallic. Ionic bonds form due to the transfer of an electron from one atom to another. Covalent bonds involve the sharing of electrons between two atoms.
Hope this helps !!! Good luck!!! ;)
Answer:
Astrocytes
Explanation:
Astrocytes are specialized glial cells found in the brain and spinal cord, they are responsible for maintaining the electrolytic composition of the cerebrospinal fluid, induce the formation of the blood-brain barrier and act as a support and guide for neurons during migration. They keep the ionic composition of the extracellular fluid of the central nervous system through the water channels, Aquaporin-4 (AQP4) and K channels, located in the pedicle processes of the astrocytes in the perivascular space, these cells exchange K and water in said perivascular medium away from the neurons. Astrocytes selectively edematize during hypotonic stress, while neurons do not.
