This question is incomplete because the images a section 2 are not given. I searched for the complete question but could not find it. However, based on my knowledge and the characteristics of the tundra this is the answer.

The correct answer is C. The climate is harsh, which limits the number of species that can live there.

Explanation

The tundra is the name of an ecosystem that occupies a fifth of the earth's surface, mainly in the northern hemisphere, this is characterized by having a frozen subsoil that limits the emergence and growth of natural vegetation and trees. This ecosystem is the coldest on the planet due to its location near the poles, its landscape is characterized by a layer of snow that covers most of the ground. In addition, the climatic conditions are extreme, which limits the number of plant and animal species that can live there. According to the above, the correct answer is C. The climate is harsh, which limits the number of species that can live there.

Georgia [21]
The answer is right below.

The bulk of this species’ diet consists of fish in the teleost infraclass, including dragonfish, rattails, anglerfish, and more. They are also known to feed on crustaceans and cephalopods like squid.

These sharks will prey on fish found both on the sea floor and in the water column. Because they are so slow moving, scientists believe these sharks are ambush predators. Their pinkish-red skin actually blends in when in the deep sea.

The germ cell has 2 sets of chromosomes, and the four gametes will each have one set of chromosomes. ​​​​​​​ To have enough DNA
ICE Princess25 [194]

Answer:

This question lacks options, the options are:

A. Halved

B. Doubled (x2)

C. Quadrupled (x4)

D. Octupled (x8)

The answer is B.

Explanation:

Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).

However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.

MrRa [10]
There are choices for this question namely:

<span>A) genetic bottleneck. 
B) sexual selection. 
C) habitat differentiation. 
D) founder effect.
</span>
The correct answer is founder effect. The definition of founder effect is the loss of genetic variation when a new population is established in a small number of individuals from a larger population. The larger population in the context is the ecosystem in Hawaii before it rose from the sea surface. After it rose above the sea surface, most organisms will not be able to survive in land but there will be a small population that can evolve from there.
