Answer:

I'm thinking maybe B, illustrates the principle of natural selection.

Explanation:

This example shows that, once a particular event happens in a species' ecosystem that negatively affects their lifestyle, natural selection occurs and kills off those with a disadvantageous adaptation (in this case the narrow-beaked finches, since they could no longer eat insects but did not have the beak size to crack seeds), allowing those with the advantageous adaptation (in this case, the thicker-beaked birds) to prosper.

Which hormone causes the regrowth of the endometrial lining of the uterus?
makvit [3.9K]

Answer:

progesterone

Explanation:

Progesterone, unlike estrogen, has no activity on determining female sexual characteristics. Progesterone activity is to prepare the uterus for possible pregnancy by growing the endometrial lining of the uterus and receiving the fertilized egg and stimulating milk production.

Progesterone is directly responsible for maintaining and sustaining the fetus in the womb, stimulating, during the first two weeks of pregnancy, the fallopian tube and endometrial glands to secrete nutrients essential for the zygote. Uterine contractions are inhibited to prevent the fetus being expelled as it blocks prostaglandin production and decreases oxytocin sensitivity.

Write 16 facts about the carbon cycle
mario62 [17]

-Some objects can store carbon for many years and are known as carbon sinks.

-Carbon in the air is attached to oxygen and is known as a molecule called carbon dioxide.

-Plants use carbon dioxide in the air to make their own food through a process called photosynthesis.

-When plants die and decompose, they could eventually become a fossil fuel and be burned to return as carbon dioxide in the air.

-Carbon dioxide in the atmosphere is helpful because it helps keep our planet at a livable temperature.

-The ocean takes up quite a bit of carbon dioxide to provide nutrients for its plants.

-Living substances that contain carbon are known as organic.

-Carbon is the second most abundant substance in living organisms behind water.

-Humans can obtain carbon in the carbon cycle by eating plants or eating animals that eat plants.

-Roughly 99% of carbon is stored deep within the Earth’s surface.

-Carbon is so important that there is an entire branch of chemistry dedicated to it called organic chemistry.

-Carbon is very versatile in that it can combine with up to four other elements at the same time and can exist as a solid, liquid, or a gas.

-Carbon-14 dating is a technique used to determine the age of ancient artifacts and fossils.

-Carbon is number 4 on the most abundant elements in the universe list.-

-The origin of the word carbon comes from the word carbo which is Latin for coal.

I hope this helps

Ftsz, mreb, and cres proteins regulate the shape and structure of bacterial (prokaryote) cells. these proteins are homologous to
Makovka662 [10]
Ftsz, mreb, and cres ,proteins regulate the shape and structure of bacterial prokaryotic cells. These proteins are homologous to the Cytoskeleton in eukaryotes. Homologous meaning they have the same evolutionary origin but not necessarily having the same function. Cytoskeleton forms a framework for the movement of organelles around the cytoplasm, most organelles are attached to the cytoskeleton.
