When an organism reproduces they pass on their genetic information in the DNA to their<span> offspring.

The fossils from
Australopithecus provide evidence for evolution because some parts of the bone
that contains the DNA of it can be identified as this type of animal. They can
be detected through the use of carbon dating devices.
Answer:
The ovarian cycle regulates endocrine tissue preparation, and egg release in female body.
The first half of the ovarian cycle as the follicular process. Slowly growing rates of FSH and LH are causing follicle development on the ovary surface. This cycle makes the egg primed for ovulation. As the follicles develop they start releasing estrogens and low progesterone levels. Progesterone locks the endometrium in order to help ensure pregnancy. It takes about seven days to travel ovum through the Fallopian tube and to get implanted in uterus. There are 30-60 cells at this point of evolution, called the morula. If there is no pregnancy implantation the lining would be sloughed off. estrogen levels increase after around 5 days, and the menstrual cycle enters the proliferative process. The endometrium starts to regrow, replacing the weakening blood vessels and glands at the end of the last cycle.
In order to calculate the distance between two alleles/genes that are found in the same chromosome, we need to know how often crossing-over happened (recombination frequency). We know from the text that white eyes were linked to miniature wings and that wild type eyes were linked to wild type wings, so any phenotype that's contrary to these parent combinations are a result of crossing-over. We know then that 230 flies + 240 flies were a result of such recombination. To calculate the recombination frequency we only need to divide these flies (total of recombinant flies) by the total of flies in the offspring and turn it into percentage.

=0.47
0.47*100%=47%
47 map units is the distance between the genes <span>for eye color and wing length.</span>
Answer:
It destroy both harmful and beneficial microbes.
Explanation:
If scientist added a chemical to destroy the arctic microbes, the beneficial as well as harmful microbes also eliminated from that area where chemical is applied. The removal of harmful microbes is a good thing but the removal of beneficial microbes brings instability in the environment. These beneficial microbes helps in the recycling of nutrients for the plants present there. So the negative effect of chemical is that it also effect the beneficial microbes which are necessary for the ecosystem.
