0% of the population has a straight hairline
Answer:
VII. Anaphase II
Explanation:
During metaphase II, fibers of the spindle apparatus drive chromosomes to the cell equatorial plane, where they line up. Sister chromatids are holden together until they reach <u>Anaphase II</u><u>,</u> during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase II, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole
Answer:
A) Chromosomes are made of DNA
C) Alleles are the different forms of a gene that can exist
D) Chromosomes contain genes that control the inheritance of traits.
Explanation:
Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
Answer:. have chloroplasts and a cell wall
Explanation:All living organisms are made up of cells.some organism are made up of one cell (Unicellular) and other organism are made up of many cells(multicellular).
Cells are made up of organelles and the organelles present in a cell differ in animals cells and plant cells.
A feature that animals cells have which plant cell do not have is the presence of centrioles.
Features that plant cell have which animals cells do not have are the presence of chloroplast ,vacuole and cell walls.
Animals do not produce their food but plants do.Green Plants produce their food through chloroplast,which contains chlorophyll.
Plants has cells walls which is rigid and made up of cellulose,lignin and pectin.this rigid structure of the cell wall contributes to the rigidity of plants stems and roots.
Option A is incorrect because plant and animal cells have mitochondria.
Option B is incorrect because plants cells have both plasma membrane and cell walls.the cell wall surrounds the plasma membrane.
Option C is incorrect because plants contains Golgi apparatus and vacuole
Isn’t it 37.2 trillion cells if that is wrong sorry
