Answer:
A
Explanation:
The The one that is appropriate is A because phytoplankton to fish is like the bacteria that is on the bottom of the floor in the water and the fish could eat that phytoplankton and then your shark and whale could eat the fish and get the phytoplankton so your answer is A
"The cell is in telophase I and will enter meiosis II next" is the one among the following choices given in the question that is the best conclusion you can make about the life cycle of this cell. The correct option among all the options that are given in the question is the first option or option "A". I hope it helps you.
Complete question:
A geneticist crossed pure breeding black mice with pure breeding brown mice. All the 992 mice in F1 generation had black coats. When these mice were crossed, the yielded 961 black coated mice and 317 brown coated mice. How could you account for the ratio of black coated to brown coated mice in the F2 generation? Select all that apply
- The F1 male produced two kinds of sperm, half carrying an allele for black coat color, and half carrying an allele for brown coat color.
- The brown allele segregates together with the black allele and disappears in the F1 generation.
- The F1 female produced two kinds of eggs, half carrying an allele for black coat color, and half carrying an allele for brown coat color.
- An approximately three-to-one ratio of black to brown coated mice in the F2 generation is accounted for by the black allele being dominant over the brown allele.
Answer:
- The F1 male produced two kinds of sperm, half carrying an allele for black coat color, and half carrying an allele for brown coat color. APPLIES

You will find the complete question, answer, and explanation in the attached files, due to technical problems.
The answer is nitrogen-fixing bacteria.
<span>Plants
are not able to directly use atmospheric nitrogen. It must be converted into different
form through a nitrogen cycle. In the process of nitrogen
fixation, nitrogen fixing bacteria converts atmospheric nitrogen into
ammonium. In the process of assimilation, plants incorporate
ammonium into proteins.</span>
Some legumes have a symbiotic relationship with bacteria that
live in their root system. These bacteria are called Rhizobia and have
the ability of nitrogen-fixation.
Answer
Nerve
Explanation:
The CNS consists of brain and spinal card that receives information, interprete it and send response.
The peripheral nervous system consist nerves that leaves the spinal card and brain and transmit or receive signals from various areas of body.
A nerve comprises of bundles of exons or dendrites surrounded by connective tissue. Sensory neurons contain afferent axons and motor neurons have efferent fibers. In central nervous system, a bundle of axons is called tract and in the peripheral nervous system it is called as nerve.
Axons are slender long projections of neuron which transmit the signal. Exon length may vary from 1um to 20um. The longest exon in human body runs from spinal cord to base of each foot.
