When a disease kills a large amount of the rabbit population which is the competition among wolves most likely. So, the correct answer is (B).
Competition is the interaction of individuals that fight for a common resource which is in limited supply, but more likely can be defined as the direct or indirect interaction of organisms which leads to a change in fitness when the organisms share the same resource. This results in the negative effects on the weaker competitors.
There are three forms of competition among the animals. Out of three. two of them , interference competition and exploitation competition, are categorized as real competition and the third form is apparent competition which is not a real competition.
Interference competition occurs directly between different individuals but exploitation competition and apparent competition occur indirectly between different individuals.
Thus, when a disease kills a large amount of the rabbit population which is the competition among wolves most likely. So, the correct answer is (B).

where r is the radius of the sphere;
π is a constant that is roughly equal to 3.
Calculate the surface area of a sphere with a radius of 7 meters using the simple approximation above.
Answer:
DNA, ribosomes, plasma membrane and cytoplasm are the structures that are found in both.
Explanation:
Prokaryotes are the organisms that do not have a nucleus and other membrane-bound organelles and eukaryotes have a membrane-bound nucleus and another membrane-bound organelle.
Apart from this there are some similarities between prokaryotic and eukaryotic cell like both have a highly selective cell membrane, they both have cytoplasm, both have DNA and ribosomes which is responsible for the expression of genes. Therefore DNA, ribosomes, plasma membrane, and cytoplasm are the structures that are common in both prokaryotes and eukaryotes.
Prokaryotic and eukaryotic cells, despite their differences, share four basic structures: the plasma membrane, cytoplasm, genetic material, and ribosomes.
The question you've asked pertains to the similarity between prokaryotic and eukaryotic cells. Despite their differences, all cells, whether they are prokaryotic or eukaryotic, share four basic structures. These include: the plasma membrane which acts as a barrier, cytoplasm which is a jelly-like substance inside the cell, genetic material (both DNA and RNA), and ribosomes where protein synthesis occurs. Prokaryotes and eukaryotes often come in different shapes, but these four structures always remain constant.

Explanation:
The answer is that cnidarians lack triploblastic development. Cnidarians, such as jellyfish, sea anemone, and hydra, exhibit diploblastic development. This means that they have only two germ layers: the ectoderm and the endoderm. To understand triploblastic development, let's break it down. Triploblastic development refers to the formation of three germ layers: the ectoderm, the mesoderm, and the endoderm. These germ layers give rise to different tissues and organs in the body. In contrast, cnidarians lack the mesoderm layer. The mesoderm layer is responsible for forming muscles, connective tissues, and other internal structures. Since cnidarians do not have this layer, they are considered diploblastic. Let's use an example to illustrate this. Imagine you have a triploblastic organism, like a human. In a human, the mesoderm layer gives rise to muscles, which allow us to move. But in cnidarians, since they lack the mesoderm layer, they do not have true muscles. So, to summarize, cnidarians lack triploblastic development because they do not have the mesoderm layer. Instead, they exhibit diploblastic development, with only two germ layers: the ectoderm and the endoderm
As far as I know about black snails is the fact that the Black Mystery belongs to the genus Pomacea, Ampullariidae family. This family is also often called Apple Snail, and it contains a nearly 120 different species of snails. I know that increase in the number of black snails can best be explained by the high teperature in which black snails are. It's the main reason of their reproduction.
B. coded in proteins on the surface membrane.
C. coded in either RNA or DNA.
D. found only in bacteriophages.
2. A lytic infection concludes with the
A. insertion of viral DNA into the host cell’s DNA.
B. production of a prophage.
C. bursting of the host cell.
D. production of messenger RNA.
3. A prophage is made of
A. bacteriophages.
B. carbohydra
A virus's ability to replicate itself is encoded in either DNA or RNA. The creation of biological viruses throughout the infection process in the target host cells is referred to as viral replication and lytic cycle.
Thus, Viruses must initially enter the cell in order to begin viral replication. This packaging allows the virus to spread to new hosts by making copies of itself. The host cell bursting is the correct response.
The host cell bursts at the end of a lytic infection. A lytic cycle is produced when an infected cell and its membrane are destroyed. There are pathogenic bacteriophages, which exist as free-floating molecules, that exclusively use the lytic cycle.
Viral DNA is used to create prophages. Bacteriophage genomes that are integrated and inserted into circular bacterium DNA chromosomes are known as prophages and lytic cycle.
Thus, A virus's ability to replicate itself is encoded in either DNA or RNA. The creation of biological viruses throughout the infection process in the target host cells is referred to as viral replication and lytic cycle.
