The table below shows salinity tests from coastal Louisiana following a salt water influx during hurricanes Katrina and Rita. If efforts are not made to reduce the salinity in these areas, what is the most likely long term effect?
A growth in the population of salt-intolerant types of plants
A shift in species composition to less salt-tolerant plants
A shift in species composition to more salt-tolerant plants
An increase in the diversity of salt-intolerant plants
Answers
A shift in species composition to less salt-tolerant plants is the most likely long term effect.
What are the characteristics of salt-tolerant plants?The salt tolerance test is performed using Tryptic Soy Broth with added sodium chloride (regular table salt) to create an overall salt concentration of 6.5%. It is a selective medium which tests the ability of an organism to survive in a salt-rich environment.
The salt tolerance of a plant is often defined as the degree to which the plant can withstand, without significant adverse effects, moderate or high concentrations of salt in water on its leaves or in the soil within reach of its roots.
Hypersensitivity to catecholamines may be the cause of salt sensitivity. A low sodium concentration in saliva deserves further study as a simple screening test to identify salt-sensitive subjects.

The recombination frequency between linked genes A and B is 40%, between B and C is 20%, between C and D is 10%, between C and A is 20%, and between D and B is 10%. What is the sequence of the genes on the chromosome?
Answers
Answer:
ACDB (or BDCA)
Explanation:
The linked genes A and B have a greater frequency of recombination (40%) and therefore they are found furthest away on the chromosome. Conversely, the smaller distance is between D and B, which exhibit a lower frequency of recombination (10%), while C is localized at the same physical distance of both A and B (20%), so the physical map is ACDB.

While some mutations can benefit an organism, others are harmful and can lead to cancer. Which of the following best describes how mutations can cause cancer in an organism?
O Cell division becomes uncontrolled when mutations occur in genes that regulate cell division.
O Cells with mutations outnumber and consume normal cells that do not have mutations,
O A mutation can attack a cell's DNA and cause an autoimmune response in the cells.
+
O Mutations cause cells to become unable to divide and the cells die in masses, forming tumors.
Answers
Answer:
Cell division becomes uncontrolled when mutations occur in genes that regulate cell division.
Explanation:
Answer:
The answer is "A."
Explanation:
Cancer develops when the cells in the body are constantly dividing uncontrollably. In humans, cancer is often the result of a negative mutation genetically. The other answers are wrong and do not match the way cancer forms. So, A will be your answer.
Oxygen has 6 valence electrons. How many electrons does an atom of oxygen need to become stable?
two
four
six
eight
Answers
Answer:
2 electrons
Explanation:
According to the octet rule, atoms must bond to each other, sharing electrons among themselves in an attempt to complete their valence shell (last layer of the electrosphere). In other words, an atom becomes stable when it has 8 electrons in its valence shell.
Oxygen atoms have six electrons in their valence shell, so to achieve the stability suggested by the octet rule (eight electrons), these atoms share two electrons, forming one oxygen gas (O₂) molecule.

g When an oxygen molecule diffuses from the air in the lung into the plasma in a capillary in the lung, how many times does it have to diffuse through a plasma membrane before reaching the plasma
Answers
Answer:
The answer is 2.
Explanation:
When oxygen gets into the lungs, it first needs to diffuse through the alveoli and into the blood. Then through the veins and capillaries, it diffuses into all the calls in the body. It does so quite easily because it is a nonpolar and a very small molecule with a low concentration inside the cell. This gives it the ability to diffuse easily through the cell membrane.
So the number of times that oxygen has to diffuse through a plasma membrane is two.

Both the parents are Ww because their daughter lacks a widow's peak, which means they both must carry the recessive gene. If we conduct a Punnett Square with the parents genotypes which are both Ww, the son has a 25% chance to be WW, and a 50% to be Ww and a 25% chance to be ww (which he is not since he has a widow peak!). The son could be WW or Ww. In order to find out which genotype the son has, we'd have to look as his offspring!

When a hawk eats a mouse and then uses the energy from the mouse to fly,

Answers
Answer:
It would be Chemical to mechanical
Explanation:
Because food is a chemical source and the hawk flying is a mechanical source.
When a hawk eats a mouse and then uses the energy from the mouse to fly in this case chemical energy is converted to mechanical energy.
What is food chain?Food chain is the sequence of flow of energy in which all the levels get proper food supply and it is the food web which starts from producer and ending at top such as predator species, decomposer and detritivores.
In food chain plants play the role of producers as they are autotrophs and they prepare their own food in the presence of sunlight and all other organisms depend upon plant for food so they are known as producers in the food chain.
The main role of food chain is to understand the importance of each organisms and how they are depend on each other as well as to understand the role of food chain in maintaining ecological balance.
Therefore, When a hawk eats a mouse and then uses the energy from the mouse to fly in this case chemical energy is converted to mechanical energy.

Explain why it makes sense to use the word translation to describe protein synthesis and why it would not make sense to use the word translation to describe mRNA synthesis?
Answers
Answer:
The application of the word translation makes sense at the time of describing the synthesis of protein as the language of nucleic acids is transformed into the language of polypeptides by the phenomenon of translation. On the other hand, it will not be suitable to describe the synthesis of mRNA using the word translation as the nature of the biomolecule stays similar because both the DNA and the product of DNA, that is, mRNA are nucleic acids.

What is crossing over?
When it comes to genetics and genomics, the term "crossing over" describes the DNA exchange that takes place between paired homologous chromosomes (one from each parent) during the development of egg and sperm cells.
This process leads to novel allele combinations in the gametes (egg or sperm) produced, ensuring genomic variety in any offspring born.
When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father.
