The correct answer is C. It continues to eat the amount of food it does normally.


When rat's ventromedial nucleus is destroyed the rat will become more hyper physics and it continues to eat until it has doubled its normal weight.

Ventromedial nucleus of hypothalamus is termed as nucleus of hypothalamus.

It is a distinct morphological nucleus which involved in terminating hunger, fear, sexual activity and thermoregulation.

Ventromedial nucleus of hypothalamus is divided into subdivisions. For example, dorsomedial, ventrolateral, central and anterior. VMN is most commonly associated with satiety. In rats ventromedial nucleus is caused by over-eating and obesity.

Answer:

B (begin to eat uncontrollably)

Explanation:

The ventromedial nucleus also known as the ventromedial hypothalamus is a distinct nucleus located inside the hypothalamus of the brain. It is known as a nucleus because it is a distinct group of neurons within the hypothalamus. The nuclear region is involved in terminating hunger, bringing about satisfaction in organisms.

It is responsible for the feeling of satisfaction or fullness after eating, in organisms. Its stimulation induces cessation of eating in an animal. It tells organisms when they have eaten enough, hence, to stop eating.

However, lesions or damage to this satiety center (Ventromedial nucleus) results in overeating and subsequently obesity because the organisms are not getting the information that they are full.

Hence, when the ventromedial nucleus of a rat is destroyed, it no longer gets the awareness of satisfaction when eating, hence, it eats uncontrollably.

maw [93]

Answer:

There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).

What are some functions of noncoding DNA?
Artyom0805 [142]

Answer:

Explanation:

The non-coding DNA sequences forms the part of the organism's DNA. It is the part of the human genome which does not encode for any protein sequence. Some of the non-coding DNA may be transcribed into into any of the functional non-coding RNA molecules such as ribosomal RNA, transfer RNA and regulatory RNA. Other functions of the non-coding DNA involve translational and transcriptional regulation of the protein coding sequences, origin of DNA replication process, scaffold attachment, telomeres and centromeres.

What is the function of helicase in dna replication? see concept 16.2 (page 322)?
Salsk061 [2.6K]
The function of Helicase in the process of DNA replication is to untwist the double helix and separating the two DNA strands. This action of helicase creates the replication forks and replication bubbles where the process of replication is initiated. Their main role is the separation of double-stranded DNA into single strands allowing each strand to be copied during the process of replication. It may also function in other cellular processes where the double-stranded DNA must be separated, including transcription and repair. <span />

Hello. You forgot to enter the necessary data for this question to be answered. The data are shown in the figure attached below:

Answer:

Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins.

Explanation:

Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins, this can be seen by the degree of genetic similarity between these two species, since the Red-capped Robin has 98.2% of genetic similarity .

When two species have the same common ancestor, these species have great genetic similarity and the more recent this ancestry is, the greater the genetic similarity between the species.
