The correct answer is option C, halophile

Reason -

Halophiles are organisms that live in extreme climatic conditions such as high level of salt concentration which is five times larger than the salt concentration of the ocean for example Dead sea, the great salt lake, evaporation water bodies etc.  

Halophile have enzyme which causes selective import of K+ ions that regulates the osmotic pressure by increasing the internal salinity.

Can someone answer this pls??
Lunna [17]

Answer:

75% brown, 25% white

Explanation:

This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).

According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.

Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:

¾ or 75% brown and ¼ or 25% white

Is the heme molecule attached to hemoglobin during the primary level or tertiary level of organization?
djyliett [7]

Answer:

Tertiary.

Explanation:

Primary structure of proteins refers to the order of amino acids that make up the protein. The heme is an nonprotein non-amino acid, so it is not involved at this stage.

Tertiary structure of proteins is the overall 3-D folding of the protein (it comes after secondary, which involves folding into a repeated pattern). The heme bonds to its correct position on the hemoglobin during this stage and helps in correct folding.

Which vitamin can be synthesized in significant amounts by humans and, therefore, may NOT be essential
Nadya [2.5K]

Answer:

The correct ansqwer is- Vitamin D

Explanation:

Vitamin D is the vitamin that can be synthesized by the human body itself therefore it is not an essential vitamin for human beings. Human skin is the part that helps in making this vitamin in humans.

The natural form of vitamin D is vitamin D3 which is formed by the sunlight exposure on the skin. When we expose our skin in the sunlight the UV radiation penetrated our skin and converts provitamin D3 into pre-vitamin D3 then this previtamin can be isomerized into the natural form of vitamin D Which is vitamin D3. So the right answer is vitamin D.
