solniwko [45]
Cellular respiration is also a catabolic process because it breaks the small molecules from digestion into even smaller ones as ATP is created. These are both very important processes, because ATP is what your cells use to produce body heat, move your muscles, and other essential bodily functions.

State one way a complete blockage at location X would affect the reproductive process ? Please answer !!
Romashka [77]

Answer:

There would be no fertilization.

Explanation:

When the fallopian tube is blocked, even after ovulation (an egg released by the ovary), it will be unable to travel down the fallopian tube towards the uterus. This way, even when the sperm swim up to the tube (where fertilization  of the egg usually occur) after copulation, it will be unable to meet the egg and fertilize it. There will never be conception as long as there is blockage on location X.

Ddt was widely used as a pesticide for 20 years. Its use was banned after studies showed severe side effects were evident in hum
emmasim [6.3K]

Answer:

One major side effect of DDT was the extreme damage to bird populations. DDT caused the shells of bird eggs to become extremely thin, which made them prone to breaking from minor disturbances and failing to thrive due to temperature regulation issues. It also slowly poisoned animals, especially birds that fed on insects that were poisoned by DDT. A notable bird species that was affected by DDT is the bald eagle. At one point in the 1960s, bald eagles nearly went extinct due to various effects of DDT. The threat of one of the most recognizable animals in America going extinct led to lawmakers trying to ban DDT.

What form does carbon come out of animals
