It allows the scientist to determine the effect of the changed variable , it also allows samples and organisms to be tested under comfortable conditions
1. False- a species would know what is their kind and what is not
2. True- if the parents have the trait it is most likely the offspring will have it also

4. False- natural selection is when a breed is naturally selected to have certain traits in that specific area
(Sorry if it’s wrong hope this helped :) )
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: (anaphase) so the first one
Explanation:
The renal<span> artery carries blood into the </span>kidneys, which once there is filtered by nephrons. The waste filtered by these nephrons is combined with water to makeurine<span>. As the </span>urine is produced<span> it drains out of a tube called the ureter and collects in the bladder
