Can you show me the following??
see plants are also living beings, they also need oxygen for respiration. There would be less carbon dioxide available for plants for photosynthesis. Atmosphere will be clean, less polluted, clean water. No fighting, peaceful, cool environment
Answer:
Cross a non-floppy-eared male to a floppy-eared female and observe if males offspring have the floppy ear trait
Explanation:
Mammals (e.g. dogs) have two sex chromosomes: X and Y. In the XY sex-determination system, the female gamete (i.e., the ovum) contributes to an X chromosome, while the male gamete (i.e., the sperm) contributes either an X chromosome or a Y chromosome: normal females are XX and normal males are XY. In consequence, a male always inherits its X chromosome from the mother and its Y chromosome from the father. In this case, the presence of the floppy ear trait in all males F1 offspring obtained by crossing a non-floppy-eared male to a floppy-eared female indicates that this trait is linked to the X chromosome because males inherit the floppy ear trait from the mother.
Answer:
(A) two
Explanation:
A heterodimeric protein consists of two polypeptides (a polypeptide is a chain of amino acids) that differ in amino acid composition, number or order in the chain sequence. Each polypeptide makes a different subunit of the protein.
One gene encodes one polypeptide, so if the protein has two different polypeptides, two genes are required to form this protein.
Answer:
Option-B
Explanation:
DNase I is an enzyme which acts on the DNA in its single-stranded, double-stranded and chromatin form.
The DNase acting sites on the DNA is known as the DNA I hypersensitive site. The DNase I hypersensitive site allows the DNase I to act as the condensed form becomes less condensed. This mechanism can be associated with the transcription as, during transcription, the DNA becomes less condensed and is open to DNase I enzyme.
Thus, Option-B is correct.
