The _______ is moving end of muscle whose tendon attaches to a bone

Which section of the brain is responsible for coordinating muscle movements

jarptica [38.1K]

Answer:

The cerebellum (back of the brain) and the brainstem (middle of the brain)

Explanation:

Muscle movement coordination can be voluntary or involuntary. There are different sections of the brain responsible for the two;

Voluntary movement of muscles is coordinated by the brainstem in addition to other functions such as sneezing, swallowing, vomitting, etc.
Involuntary coordination of muscles is controlled by the cerebellum in addition to maintaining posture, balance and body equilibrium.

Hence, both the cerebellum and the brainstem are responsible for coordinating muscle movement.

Color in McIver beetles is determined by two alleles at one gene locus. McIver beetles must have a heterzygous genotype (genotyp

seraphim [82]

Answer: The frequency of brown beetles is 0.32.

Explanation: The frequency of A1 allele is 0.8. As p+q=1, or the sum of dominant and recessive frequencies equals 1 or 100%:

1 - 0.8 = 0.2

In Hardy-Weinberg principle,

$p^{2} + 2pq + q^{2} = 1$

2pq represents the frequency of heterozygote individuals, so:

genotype A1A2 = 2*0.8*0.2 = 0.32.

Thus, the frequency of brown beetles (A1A2) in the population is 0.32.

Can someone explain the process of RNA editing?

Talja [164]

The process of RNA editing is the alteration of the sequence of nucleotides in the RNA after it has been transcribed from DNA, but before it is translated into a protein. RNA editing occurs by two distinct mechanisms:Substitution editing and Insertion/deletion editing.

Substitution editing is the chemical alteration of individual nucleotides. These alterations are catalyzed by enzymes that recognize a specific target sequence of nucleotides:

*Cytidine Deaminases that convert a C in the RNA to uracil.

*adenosine deaminases that convert an A to inosine,which the ribosome translates as a G.Thus a CAG codon (for Gln) can be converted to a CGG codon (for Arg).

*Insertion/deletion editing is the insertion or deletion of nucleotides in an RNA.

These alterations are mediated by guide RNA molecules that base-pair as best they can with the RNA to be edited and serve as a template for the addition( or removal) in the target.
