They emit radiation as they decay C

forsale [732]3 years ago

Answer: C. They emit radiation as they decay.

Explanation:

The radioactive isotopes are the elements that exhibit unstable and heavy nuclei. The isotopes disintegrate or decay by fission to form entities that exhibit stable nuclei. The radioactive elements are the parent atoms which disintegrate into daughter products and subatomic particles. This disintegration process liberates a lot of energy in the form of radiation like gamma rays. Hence, the type of radiation emitted by the disintegration or decay process of the radioactive isotopes can be useful to detect their elemental type and their origin.

The fossil record of birds is incomplete because bird skeletons are
Bogdan [553]
Bird skeletons are very delicate, and therefore, difficult to be preserved.  The bones of the birds are soft. The small animals are very prone to physicochemical as well as biological decay. This is why the fossil record of bird is incomplete and well-preserved fossils of birds are rare to find, except at a few unusual sites.

What is a red tide ?
netineya [11]

Red tide is a common name for algal blooms, which are large concentrations of aquatic microorganisms, such as protozoans and unicellular algae.

The upwelling of nutrients from the sea floor, often following massive storms, provides for the algae and triggers bloom events

Several experiments were required to demonstrate how traits are inherited. Which scientist or team of scientists first demonstra
Snowcat [4.5K]

Answer:

Frederick Griffith was the first scientist who discovered that cell contains some components that can be transferred to another cell and cause a permanent change(transformation) in the new cell.

To prove this he performed an experiment in which he took two strains of <em>Streptococcus pneumoniae</em> which contain one rough strain and one smooth strain. Rough strain was non-virulent strain and smooth strain was virulent strain.

So he injected smooth and rough strain in mice and saw that mice die when virulent strain is injected and survive when non-virulent strain is injected. Then he injected heat killed virulent strain in which mice survived.

Then he added remain of heat killed bacteria with live smooth strain of bacteria and infected the mice and saw that the mice was killed by non-virulent smooth strain of streptococcus.

After this experiment he concluded that cells contain some component later identified as DNA which can be transferred to new population of cells and transform these new cells.

Instead of oxygen __________ may utilize nitrate or sulfate as their final electron acceptors
steposvetlana [31]

The answer in the space provided is anaerobic respiration. It is because this allows of having to utilize other substance than oxygen such as nitrate or sulfate to be their electron acceptors in which is for organisms that undergoes respiration.

Glucokinase and hexokinase in glycolysis
Delicious77 [7]
<h2>Answer:</h2>

Glucokinase or Hexokinase is a enzyme used at the first step of glycolysis.

<h2>Explanation:</h2>
  • Glucokinase is a Isoenzyme(enzymes which differs in the sequence of amino acids but catalyses the same reaction) of Hexokinase .
  • Glucokinase (hexokinase D) is present only in liver and pancreas whereas hexokinase is present in all cells.
  • In first step of glycolysis i.e formation of glucose-6-phosphate from glucose is completed with the help of hexokinase. In this step a ATP molecule is consumed i.e ATP is converted to ADP

Result: Glucokinase and hexokinase are used in the first step of glycolysis.
