<h2>Answer is option "C"</h2>

Explanation:

  • All in all, this procedure includes a "parent" cell parting into at least two "little girl" cells. Right now, parent cell can give its hereditary material from age to age.  
  • Meiosis, then again, is a particular type of cell division that happens in living beings that imitate explicitly. As referenced above, it produces regenerative cells, for example, sperm cells, egg cells, and spores in plants and parasites.  
  • In people, extraordinary cells called germ cells experience meiosis and at last offer ascent to sperm or eggs. Germ cells contain a total arrangement of 46 chromosomes (23 maternal chromosomes and 23 fatherly chromosomes). Before the finish of meiosis, the subsequent regenerative cells, or gametes, each have 23 hereditarily one of a kind chromosomes.
  • Hence, the right answer is option C "four strings, each a combination of different colors"

When a motor neuron and the skeletal muscle cell it innervates are at rest:?
Nuetrik [128]

<span>Particularly the skeletal muscles at rest gain most of their energy from the aerobic respiration of fatty acids. Hence fatty acids provide the majority of the energy for muscle metabolism when a person is exercising at 25% of VO2max. However, the motor neuron is at rest when a neuron is not receiving any input there will be a potential difference. Thus, the potential difference measured when the neuron is inactive and it is caled the resting membrane potential. </span>

Which component is the last to join the initiation complex during the initiation of translation?
Vika [28.1K]

Answer:

The correct answer is the third option- the large ribosomal unit.

Explanation:

The translation is the second process of the protein synthesis in which transcribed mRNA molecule and transfer RNA or tRNA and ribosomes assemble together and complete synthesis of peptide chain or protein.

The assembly of initiator tRNA to ribosome subunits at the start codon of the mRNA is the initiation complex of the translation. The initiator tRNA is basically a met-tRNA molecule.

The initiator tRNA is bound to small subunit (30S) at 5' cap and scan for the start codon of mRNA.

Start codon bind to initiator RNA and in the end larger ribosomal unit assemble to this complex to complete the initiation complex of translation.

Thus, the correct answer is option - the large ribosomal subunit

You are already familiar with the fact that different organisms often exhibit common adaptations that help them succeed in a giv
zavuch27 [327]

Answer:

*Sensory adaptation* is the common adaptation in all three sense. Sensory adaptation is the process in which changes in the sensitivity of sensory receptors occur in relation to the stimulus. All senses are believed to experience sensory adaptation.

Explanation:

This adaptation is shared as well as used differently as explained below.

1) Hearing+balance :In terms of hearing, our ears adapt to loud sound as it hits the small bones located in the inner ear. The loud sound leads the inner ear bone/s to contract. This contraction causes the reduction or delay of transmission of sound vibrations to the inner ear. Detection of the vibrations follows. However, this process of auditory adaptation usually does not work very well with loud sounds that are sudden or instantaneous. Examples of these sounds are gun shots or explosions

2)Smell :Low concentrations of several chemicals present in the air can be detected by the sensory receptors in the nose. These chemicals that we quickly detect include those in perfumes or air fresheners

A student is setting up a model to study the carbon cycle and natural sources of carbon dioxide. They create a microenvironment
Alex Ar [27]

The natural source of carbon dioxide that was left out is the calcareous shells of organisms. The major metabolic process that was left out is respiration.

<h3>What is carbon dioxide?</h3>

Carbon dioxide is one of the gases that cycle around in the universe. It is an integral part of the carbon cycle. The carbon cycle is a model that depicts the movement of carbon in the ecosystem.

The natural source of carbon dioxide that was left out is the calcareous shells of organisms. The major metabolic process that was left out is respiration.
