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<em> voluntary</em> or <em>involuntary</em>. 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.

Match the changed nucleotide sequence to the mutations that cause them

Elis [28]

Answer:

Una mutación es un cambio en el ADN, el material hereditario de los seres vivos. El ADN de un organismo influye en su aspecto físico, en su comportamiento y en su fisiología — en todos los aspectos de su vida. Por lo tanto, un cambio en el ADN de un organismo puede producir cambios en todos los aspectos de su vida.

Identify the fungus type pictured below.

MatroZZZ [7]

That would be ascomycota or sac fungi. Sac fungi are characteristically known for producing ascus. This is a sac-like structure that contains haploid spores called ascospores. Some examples of sac fungi are yeast, truffles, morels and dead man's fingers.

Basic body color for horses is influenced by several genes, one of which has several different alleles. Two of these alleles— th

Phantasy [73]

Answer:

<h2>No,</h2><h2>Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute</h2>

Explanation:

As given:

The chestnut (dark brown) allele and a diluting (pale cream) alleles show incomplete dominance, means that both the alleles in heterozygous condition show their effect. So the heterozygous show the phenotype which is intermediate of both the parents, here a horse heterozygous for these two alleles is a palomino.

There is in fact, no particular allele present for palomino, this phenotype only results due to having two different alleles for a gene. So, palominos can never be pure-breeding because they can never be homozygous.

Let P1 chestnut and P2 dilute,

Palomino is P1P2

The Punnett’s Square for palomino mated to palomino:

P1P2× P1P2

Gametes are: parent-1 P1 and P2 , parent-2: P 1 and P2

Progeny are: P1P1, P1P 2, P 2 P1, P2 P2

Genotypic Ratio: 1 P1P 1 : 2 P1P 2 : 1 P2P 2

Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute

PLEASE HELP I WILL GOVE BRAINLIEST!! What do mutations cause?

goblinko [34]

Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression. Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism.
