The system that controls and coordinates the body through hormones is the endocrine system.

Endocrine system produces hormones and then these hormones transmit the messages to various cells within the body. Hormones have great importance in our body system and even our body is functioning due to hormones. If hormones are disturbed it can lead to many diseases.

Meselson and Stahl used density labeling of DNA to show that DNA replication occurs via a semiconservative mechanism. In their e

cricket20 [7]

Answer:

The organism previously used 15N for replication so all the DNA molecules were of 15N15N type. Then the organism is shifted to a medium where only 14N is available for replication.
According to semi conservative mode of replication, a newly synthesised DNA molecule consists of one new strand and one parental strand. So after the first round of replication, All the 15N strands will synthesise new DNA strands using 14N resulting into intermediate 15N14N DNA molecules. Hence, only one band would be observed (15N14N) above the original 15N15N band since 15N14N has lighter isotope too so it will be lighter than 15N15N molecules and will lie above it.
After second round of replication, 15N strand from 15N14N would synthesise another 14N strand. 14N strand from 15N14N molecules will also synthesise another 14N strand. So now, 50% of the DNA molecules will be of 15N14N intermediate type and 50% of them will be of 14N14N type.Two bands will be observed above the original 15N15N band. One band of 15N14N molecules will be right above it and other band of 14N14N molecules will be even higher because it is the lightest band since it has only the lighter isotope of nitrogen.

A student builds a model of a DNA strand.

insens350 [35]

Answer:

There is no attachment to this question, however, the base sequence on the model built by the student is: CAGCCATC

The options of the bases on the complementary model are:

A) CTACCGAC

B) GUCGGUAG

C) GTCGGAAG

D) GTCGGTAG

The answer is D

Explanation:

A DNA molecule is a polymer biomolecule made up of nucleotide bases. It is a double stranded molecule, with each strand containing nucleotides held together by hydrogen bonds. The pairing of nucleotides in one strand of DNA to another follows the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine binds to Thymine (A-T) while Guanine binds to Cytosine (G-C).

According to this question, a student builds a model containing the base sequence: CAGCCATC, the model that contains bases that are complementary to the ones built by the student is: GTCGGTAG

zalisa [80]

Answer:

The correct answer is negative feedback.

Explanation:

Negative feedback is considered the mechanism that frequently regulates biological reactions in the body. Negative feedback helps reduce the stimulation of some processes, such as controlling the temperature.

It can be seen that negative feedback works by redirecting some processes that go to one point directs a degree of that process to a different location.

In this case, on the temperature, the feedback is responsible for putting the system to work from the moment it starts to sweat using the different processes to regulate the temperature. This process uses help from enzymes and body pathways.

I hope this information can help you.

The molecular clock (based on the molecular clock hypothesis (MCH)) is a technique in molecular evolution that uses fossil constraints and rates of molecular change to deduce the time in geologic history when two species or other taxa diverged. It is used to estimate the time of occurrence of events called speciation or radiation. The molecular data used for such calculations is usually nucleotide sequences for DNA or amino acid sequences for proteins. It is sometimes called a gene clock or evolutionary clock.
