Answer:
The answer is C.
A 5 percent increase in the reproductive success of some genotypes, but a 5 percent decrease in the reproductive success of other genotypes
Explanation:
Incomplete question, here is the full question: https://quizlet.com/153540854/biology-107-part1-flash-cards/
For the genetic structure of a population to change, we can either depend on natural selection or mutations but there has to be an imbalance.
The answers given in the options A and B are referring to changes in genotypes which surely affects the genetic structure of the population but the way these options are given is in equilibrium, meaning they create and imbalance but then counter that with something else.
In option C, some genotypes get a 5 percent increase while some get a 5 percent decrease in their reproductive success, which will most likely result in a change in the genetic structure of a population.
I hope this answer helps.
It's letter A - Obligate anaerobe.
<em>Obligate anaerobes</em> are microorganisms killed by normal atmospheric concentrations of oxygen. A <em>facultative anaerobe</em> prefers to produce energy in the presence of oxygen but can survive without it. <span>A <em>photoautotroph </em>is an organism that converts light energy into chemical energy. </span><span>Prokaryotes may perform </span>aerobic<span> (oxygen-requiring) or </span>anaerobic<span> (non-oxygen-based) metabolism and some can switch between these modes. Since we're talking about an environment without oxygen and dies when exposed to oxygen, the preferable answer is A.</span>
Sunlight is the main change! sun light cannot penetrate into the deep layers of the ocean and availability of oxygen is also low there. this causes the considerable amount of organisms to live in the upper layers of the ocean and we can only observe decomposing organisms in the deeper layers!
Answer:
0.1
Explanation:
The Net Reproduction per individual per unit time (r) can be calculated as (births-deaths)/population size
Given that:
Population size of mice = 1,000; Birth = 500; Death = 400,
Net reproduction rate (r) = (births-deaths)/population size
r = (500 – 400)/1000
r = 100/1000
r = 0.1
The Net reproduction per individual per unit time (r) is 0.1
The answer should be competitive inhibitors
