B. carry information from genes to ribosomes.
C. transfer amino acids to ribosomes.
D. make DNA.
Starting at least level up to the largest as organized by ecologists, see the chart below.
Answer: option C) species -> community -> biosphereD
Explanation:
Species refers to closely related organisms (plant or animal). When different species of organisms live together in a habitat where they feed on one another and become codependent on one another, a COMMUNITY has been formed.
A BIOSPHERE, however is composed of many ecosystems i.e different species of plants, animals and microorganisms relating with their environment. Thus, a biosphere = Communities + environment
b. zooplankton
c. sturgeon
d. manatee
The organisms that live near the surface of aquatic biomes because it needs sunlight to survive are known as Phytoplanktons. Thus, the correct option for this question is A.
A Biome may be defined as a very large ecosystem that is running in nature in an unmanaged way. In a more simple sense, it is a very large area that is characterized by a particular type of vegetation. Examples of biomes may include tropical rainforests, coral reefs, grasslands, etc.
Phytoplankton may be defined as the producers of aquatic habitats. These organisms need sunlight in order to perform photosynthesis and synthesize their own food. That is why phytoplanktons live near the surface of aquatic biomes. They are autotrophic in nature.
Therefore, phytoplanktons are organisms that live near the surface of aquatic biomes because it needs sunlight to survive. Thus, the correct option for this question is A.

Answer:
The correct answer is a. phytoplankton.
Phytoplankton is derived from Greek words "phyto" meaning "plant" and "plankton" meaning "made to drift or wander". Hence, these are plant like microscopic organisms that live in large water bodies.
Like plants, they also contain chlorophyll which enable them to capture sunlight and perform photosynthesis.
In contrast, zooplankton (zoo meaning animal like and plankton meaning made to wander) are heterotrophic in nature which consume phytoplankton and other smaller zooplankton.
Consider the statement as True or False
Answer: True
Explanation:
Natural selection can be defined as the phenomenon by which the environment changes and the to fit into the environment the genetic makeup of the organism changes in order to suit into the changing environment.
The organism that is fit to suit into the changing environment is favored and the organism that does not fits into the environment dies.
So, natural selection can be said as survival of the fittest.
Answer:
Africa needs to urgently put a number of additional measures in place to speed up these advances, and to move towards eliminating the disease.
