Answer: In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Answer:
The job of both red blood cells and root hair cells is absorption. Red blood cells absorb oxygen through pulmonary veins and their capillaries in the lungs. Root hair cells, on the other hand, absorb water from the soil and transport them to adjoining cells for photosynthesis purposes.
Sorry but i only know 1.... its blood cells
According to the principle of segregation, gene pairs for a trait are split during the formation of gametes.
<u>Explanation</u>:
- This segregation was first observed by Gregor Mendel. He used pea plants for studying genetics.
- He crossed the pea plants and he discovered that traits in the offspring are not like the parental plants.
- He understands that alleles encoding the traits of each parental plant are separated during the formation of reproductive cells.
- By this only Mendel observed the principle of segregation. During meiosis only segregation of gene takes place and that produces reproductive cells called gametes.
