There is 2 sets of chromosomes in a regular/somatic cell. In this case chimpanzee have 48 total in each regular cell which means their sex cells/haploid cells have half of that which would be 12 chromosomes. (Haploid cells only have one set of chromosomes)
Correct answer: D) From bacteria living in their roots
Nitrogen is an essential plant nutrients, but it is metabolically unavailable to higher plants and animals. It is available to some species of microorganism by biological nitrogen fixation in which nitrogen is converted to ammonia with the help of enzyme dinitrogenase.
The process of breaking apart the two atoms in a nitrogen molecule is called nitrogen fixation. Plant obtain the nitrogen they need from the soil which is already fixed by the bacteria and archae.
Example: <em>Azobacter</em><em>,</em> Nostac
Venus and Neptune Has circular orbits.
<u>Explanation:</u>
The special case of an ellipse is said to be a circle. When the eccentricity of an ellipse is equal to zero it is said to be special case of ellipse. There are two planes that follow circular orbits in solar system. They are Venus and Neptune. Venus has eccentricities of 0.007. The eccentricity of Neptune is said to be 0.009.
Conic section is a term used to define the special cases of circles and ellipses It is said to be circular orbit when the ellipticity is zero. When it is in between zero and one it is known as a standard ellipse. It is said to be parabolic and hyperbolic when the ellipticity equal to 1 and greater than one respectively.
Answer:
involves accumulation of rhodopsin
Explanation:
This is because dark adaptation is the ability of the eye to react to low light sensitivity and all the rod pigments of the eye bleached out which is as a result to the bright light and this make the rods nonfunctional in the initial state . Once you are in the dark, rhodopsin regenerates and tthis lead to increase in retina sensitive continuously.
