Answer:
Ventral. The ventral cavity, the interior space in the front of the body, contains many different organ systems. The organs within the ventral cavity are also called viscera. The ventral cavity has anterior and posterior portions divided by the diaphragm, a sheet of skeletal muscle found beneath the lungs
Explanation:
Answer:
<h2>A</h2>
Explanation:
1. Sickle cell anemia is an inherited condition, disorder (disease).
2. It is a recessive condition, in which red blood cell become mutated and converted to a sickle like shape, and there aren't enough healthy red blood cells to carry oxygen throughout the body.
3. This condition normally occur when, there is inheritance of two abnormal or mutated copies of the β-globin gene, one allele from each parent.
4. β-globin gene makes haemoglobin.
5. Sickle cell anemia results when glutamic acid being substituted by valine at position 6 ( in short E6V substitution).
6. So, it a single base-pair substitution in the gene encoding the beta subunit.
Explanation:
Membrane transport proteins fulfill an essential function in every living cell by catalyzing the translocation of solutes, including ions, neurotransmitters, and numerous drugs across biological membranes
Answer:
the use of prokaryotes to clean up pollutants
Explanation:
Bioremediation, also called biological remediation, is a technique used to minimize the environmental impacts caused by pollution.
In this process biological degrading agents are used, particularly microorganisms (bacteria, fungi, yeast, enzymes, etc.), which detoxify areas contaminated by pollution. That is, we can say that bioremediation includes the use of prokaryotes to clean pollutants.
In bioremediation, prokaryotes remove or neutralize various toxic pollutants (organic and inorganic) from the environment, which are present in soils, waters (surface or underground), among others.
The microorganism used in the biological remediation process metabolizes and digests the contaminant. Consequently, it releases carbon dioxide (CO2) and water (H2O). A notorious example where bioremediation can be used is in the contamination (of soils or water resources) by petroleum and its derivatives.
There are several information's of immense importance already given in the question. Based on those information's the answer can be easily deduced.
Initial number of bacteria in the culture = 1000
Number of bacteria after t hours = 1000 (2)^t
Then
1000 (2)^t = 50000
2 ^t = 50
t = 5.6
I hope the procedure is clear enough for you to understand.
