Which step occurs in the A site of the ribosome during translation?

Biology
1 answer:
Law Incorporation [45]2 years ago
3 0

Answer:

B. An incoming charged tRNA binds to this site.

Explanation:

This is part of a process called TRANSLATION, in which mRNA is translated into proteins by the ribosomes, it comprises 3 stages: Initiation, Elongation, and Termination.

The A site is part of the ribosome, which has 1 binding site for mRNA and 3 binding sites for tRNA: A: Aminoacyl or acceptor site; P: Peptidyl; E: Exit, and it´s involved in ELONGATION, where it binds to the Aminoacyl tRNA (charged tRNA), that has the aminoacid that´s going to be added.

During upwelling, nutrient-rich water rises to the surface. How would this most likely affect the biotic components of the ecosy
romanna [79]

Answer:

Explanation:

The upwelling of nutrients rich water to the top will increase species numbers and diversity.

When a particular area has the ability to sustain live by providing food and nutrients required for growth of organism the population will greatly increase this is because nutrients is the major source of competition among species for survival and every species goes in search for it and where there is abundance of it there will be a rise in population and diversity.

Varying type of species that are diverse in nature comes together, mating occurs more diverse species are formed.

Very large premolar and molar teeth, a sagittal crest, heavy mandibles, and wide zygomatic arches are found in modern gorillas,
Dovator [93]

Answer:

The correct answer will be option- Australopithecus.

Explanation:

<em>Australopithecus</em> is an extinct genus of a large group of animals called primates. This genus is closely related to humans which may or may not be ancestors of <em>Homo sapiens</em>.

Australopithecus exhibits traits of both ape and human-like which is distinguished by the small size of the brain, smaller canine teeth but large molar and premolar teeth, broad dish-shaped face, sagittal crest, large molar teeth, flared zygomatic arches and sloping forehead.

Thus, option- Australopithecus is the correct answer.

The group names 1-8 on the periodic table
Sedbober [7]

Answer:

Explanation:

Alkali metals (rarely 'Hydrogen and the alkali metals')

Alkaline earth metals (in old chemistry this name applied only to Ca and its congeners)

Icosagens (unofficial name; aka Boron group; rarely Earth metals)

Crystallogens (unofficial name; aka Carbon group; rarely Adamantogens[a] or Merylides[b])

Pnictogens

Chalcogens

Halogens

Noble gases (rarely Aerogens). The Group name may have to be changed to the “Helium group” since oganesson is not expected to be noble.

Which list represents the proposed sequence in plant evolution?​
Phoenix [80]

Answer:

1. Bryofita

2. vascular plants

3. Seed vascular plants (gymnosperms)

4. Angiosperms

Explanation:

1. Bryofita

Around 475 million years ago, the origin of plants was thought to originate from aquatic ancestors (green algae). Adaptation to terrestrial life is proven by the presence of sporopolenin and layered gametangia that protect gametes and embryos. This adaptation occurs in bryophytes which are the first terrestrial plants. Bryofita or mosses develop into various vanations in their group. Most briolites do not have vascular tissue (water from the environment is diluted and absorbed by the SD, but some briophytes have water-carrying vessels.

2. Vascular plants

Around 400 million years ago, the evolution of plants was marked by the diversification of vascular plants (vascular plants). These early vascular plants are seedless plants, for example in the types of ferns seria into other groups of seedless plants.

3. Seed vascular plants (gymnosperms)

Plant evolution begins with the appearance of seeds, which are structures that protect the embryo from drought and the threat of environmental change. The emergence of these seed plants accelerated the expansion of plant colonization on land. Plant seeds consist of embryos and food reserves that are protected by a cover. Seed vascular plants appeared about 360 million years ago with the appearance of Gymnosperms. Gymnosperms consist of conifers with a variety of types. Conifers and ferns dominate life in the months between more than 200 million years.

4. Angiosperms

About 130 million years ago marked the emergence of flowering plants that have a somewhat reproductive structure

complicated where the seeds are protected by a room called the ovary.Because the seeds are protected in such a way that this group discusses closed seed plants or Angiosperms
