Answer:

Plant cells need chloroplast as they are the site for photosynthesis.

Explanation:

The chloroplast is the green-colored double membrane-bound organelles present mostly in cells of leaves of green plants. Chloroplasts have chlorophyll pigments which serve to trap the sunlight for the process of photosynthesis. Both light-dependent and light-independent phases of photosynthesis take place in chloroplast to form organic sugars.

Hence, chloroplasts serve as a site for photosynthesis in plants.

How many nucleotides are in 12 mRNA codons?<br><br> 12<br> 24<br> 36<br> 48
Mrrafil [7]

The correct answer is C. 36

Explanation:

In genetics, a nucleotide refers to the basic units that form genetical material. On the other hand, a codon refers to a sequence of three nucleotides in the mRNA or messenger RNA which are a set of molecules that take genetical information from ADN to the ribosome of the cell. This implies in the case of a 12 mRNA codons there are 36 nucleotides as each of the codons contains three nucleotides which means by multiplying the number of codons by three (number of nucleotides) it is possible to know the total number of nucleotides in an RNA sequence or in this case 12 (codons) x 3 (nucleotides) = 36 nucleotides.

All of these species are herbivores and share the same habitat. Coexistence, however, can occur when animals partition their nic
Alona [7]

Answer:

  • Eating different vegetables.
  • Eating at different times.
  • Eating in different places in the same region.

Explanation:

It is common for herbivorous animals of different species to share the ecological niche and the same habitat without establishing competition for resources. In this case, these animals manage to maintain a balance between their populations and the resources available for both species to survive. Three ways of doing this are:

  • Feeding on different vegetables: Even though they are herbivores, some animals prefer a specific type of vegetable, or just feed on these vegetables. We can use as an example animals that eat only fruits and animals that eat only herbs.
  • Eating at different times: Some animals have nocturnal habits, while others have diurnal habits. This is very efficient so that these animals are not competitors and are able to feed at different times
  • Eating in different places in the same region: We can use as an example two species of turtles, where one lives on the south side of the region and feeds on the vegetables found there, while the other species lives on the north side of the region and feeds on vegetables found there.
