it would affect the growth curves because you see if a bacteria affects predators (that hunt and eat preys) the number of predators would decrease as they would be killed by the infection
Less predators means more preys as they aren’t hunted down as much so they growth curve for preys would be positive while for predators it would be negative
Answer:
<u><em>Reproduction</em></u> of cells is one of the processes that help multicellular organisms maintain homeostasis.
Explanation:
In biology, homeostasis can be described as the capability of an organism to maintain its constant internal environment despite the changes in the external environment.
External factors like pathogens in the environment tend to kill cells in our body like the skin cells and the immune cells. Through the process of cell division, our cells can reproduce and hence, maintain an equilibrium of the internal conditions.
Reproduction of cells also causes growth. Hence, the process of reproduction of cells maintains homeostasis.
<u>Answer:</u>
Approximately, the oldest stromatolites are 3.6 billion years old on earth.
<u>Explanation:</u>
- Stromatolites is not only oldest earths fossil but conspiracy in that they are singular visual portal in deep time on earth.
- It is defined as laminated accumulation structure that is they stick up above sea floor .

- The study of fossil age, evolutionary, method of formation are known as paleontology.
- These specimens are considered as old fossils which are around 3.4 to 4.1 billions years old.
Answer:
A. Scientists discovered chromosomes and DNA.
Explanation:
Mendel's ideas were based on patterns of inheritance in plants. Although he identified these patterns, at the time, we did not know what the hereditary material was. This means Mendel couldn't uncover the mechanism of why he was seeing the patterns he was.
When scientists discovered chromosomes and DNA, they were able to see how Mendel's observations made sense in the context of DNA and chromosomes.
Answer:
c. mid-adulthood

This stage of life when gray hairs become overwhelming in number and he has more gray hairs than brunette( brown hair) is called middle adulthood. Middle adulthood spans from 20 to 40 years of life which may be defined differently for different culture and country.
