In the outbreak of malaria, the frequency of the recessive allele for the HbS gene will increase. The correct option is A.

<h3>What is the HbS gene?</h3>

HbS is a beta-globin gene known as sickle hemoglobin.

It causes sickle cell disease in humans.

The disease is expressed by two HbS variants or one HbS variant or one another beta-globin gene.

Malaria is caused by the plasmodium parasite, which is present in the saliva of the mosquito.

Thus, the correct option is A, the frequency will increase.

Since sun can filter to the bottom of a pond because it is shallower than a lake, what would you find at the bottom of a pond th
liberstina [14]

Answer:

The correct answer is - C. Plants.

Explanation:

As we know and also given that the pond is usually smaller and shallower than a lake. Due to this reason, ponds have plants growing on the bottom of them from one side to the other as they get enough light as there is only the photic zone in ponds.

In lakes, there are various zones present and the lakes are deep and big to the ponds and the bottom of the lakes did not get sunlight. Plants require sunlight to grow and lakes are usually too deep to get the sunlight for plants to grow on the bottom.

Evaluate the lab and data collected. What type of transport occurred in this lab? Explain your answer, including evidence from y
andreev551 [17]

To know what type of transport occurred the lab and collected data are needed. As they are not present an explanation of the different transport's types, will be given.

Water, proteins, ions, and molecules of different sizes can pass through the cell membrane using different types of transports. The transport that each molecule uses depends on the concentration, size, and polarity.

We can classify the types of transport as active and passive.

Passive transport is the one that does not need energy to happen since the molecules move from a place of high concentration to a one of lower concentration. In this group, we have:

  • Simple diffusion: small molecules in high concentration on one side of the membrane; move to the other side due to the difference in concentration.
  • Osmosis: water passes through the membrane from a place of low concentration of molecules to one of high concentration. Water moves inside or outside the cell to valance the concentration of solutes on both sides of the membrane.
  • Facilitated diffusion: uses proteins to transport large molecules, ions, or hydrophobic molecules from one side to the other. In this type of transport, we have proteins that form channels so those hydrophobic molecules can pass through the lipid membrane, and carrier proteins, which binds to a specific molecule changing their shape and transporting the molecule.

Active transport needs the<em> energy</em> to transport molecules; since it goes against the gradient's concentration. In this group, we have:

  • Sodium-Potassium pump: uses ATP to move sodium outside the cell and potassium to the inside. The ions with this transport go to where they are most concentrated.

In conclusion, there are different types of transport; they depend on the concentration or type of molecule. To find out what mechanism of transport occurred in the lab, look at the components of the experiment and analyze which of these transports could be present.

A scientist was studying bones from an individual who died thousands of years ago. Which portion of the bones was the scientist
ludmilkaskok [199]

Answer: Minerals

Explanation: The body decomposes and after about 40 to 50 years bones are mostly brittle and dry with no traces of flesh. After thousands of years bones also disintegrate (decay) leaving brittle mineral frame. The life of bones is determined by the soil type its buried in, nuetral soils takes longer then acidic soil condition.

In this case osteocytes(bone cells) are the first to decompose followed by the cartilage and bone marrow, leaving behind mineral traces that scientist can study after thousand years.
