Please please answer if you get it right I will mark brainliest How can competition contribute to evolution through natural selection?

During competition, organisms that have favorable traits for this task will survive and are said to be selected. These organisms will reproduce and pass on those traits to their offspring. Thus, the frequency of organisms with those traits will increase

Explanation: In Darwin's theory on the mechanism of evolution, competition among living things is viewed as a major part of the “struggle for existence” and therefore as a basis for natural selection (Darwin 1872).

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
