Answer:

The radiations from radioactive materials alpha, beta and gamma radiation are on the whole ionizing radiations which can harm living cells.

Explanation:

This happens in light of the fact that ionizing radiation can break atoms into bits called ions There are three kinds of atomic radiation: alpha, beta and gamma. Alpha is the minimum infiltrating, while gamma is the most entering. Regardless, every one of the three are ionizing radiation: they can thump electrons out of molecules and shape charged particles.

Keep a separation among you and the source.Utilize protecting among you and the radiation source. Lessen the time you are being uncovered.

You should:

1. Keep a distance between you and the source.

2. Use shielding between you and the radiation source.

3. Reduce the time you are being exposed.

Genetic information is transmitted from DNA to

Alexus [3.1K]

The best answer is D.

Genetic information for synthesis of a protein is transmitted from DNA to the ribosomes, which are the site for protein synthesis. This is facilitated by messenger RNA or mRNA in short.

In the nucleus of the cell, information from DNA is copied (transcribed) onto mRNA which leaves the nucleus and enters the cytoplasm where it attaches to the ribosome. The information on the attached mRNA is decoded and read ( translated) by transfer RNA (tRNA) which then brings corresponding amino acids to the ribosome to be linked together to form the protein.

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.

solniwko [45]

Answer:

A supertype entity

Explanation:

A supertype is a form of entity which has one or even more subgroups to relate to. A subtype is an entity type sub-group of entities that is relevant to the organisation and shares similar characteristics or relations which are different from certain sub-groups.

The entity supertype is a different form of entity type which has relationship with one or even more subtypes and includes subtypes ' of specific attributes.

Most of the body's calcium is found in ________.

atroni [7]

Answer:

Bone.

Explanation:

Calcium is one of the important element present in the body. Calcium plays an important role in the muscle contraction. The calcium ions also acts as a signalling molecule during cell signalling.

The calcium is present in our extracellular fluids, bones, and teeth. The major constituent of calcium is present in the bone. The bone consists of around 90% body;s calcium.

Thus, the correct answer is option (b).
