Answer:
very little oxygen
Explanation:
the atmosphere would have very little oxygen as photosynthesis produces and releases a ton of oxygen into the atmosphere. in addition plants and animals would cease to exist as they both heavily rely on photosynthesis and cellular respiration.
<span>Your skeleton is internal, which means it is contained inside of you. A grasshopper has an external skeleton, or exoskeleton, with everything contained inside it. </span>
Answer:
0% (none)
Explanation:
The female drosophila is heterozygous for X-linked recessive mutation. An X-linked recessive mutation is expressed in females only when present in the homozygous state. Therefore, the female progeny should have two copies of the mutant allele to express this mutation. Let's suppose that the genotype of the heterozygous female is X^cX and that of the male is XY. The cross would obtain progeny in following ratio=
X^cX x XY= 1/4 X^cX: 1/4 XX: 1/4 X^cY: 1/4 XY
Since none of the female progeny is homozygous recessive (X^cX^c), the cross would not obtain any female progeny expressing the X-linked recessive mutation.
Answer:
The correct answer will be option-D
Explanation:
Calvin cycle or C₃ cycle is a set of a cyclic reaction which takes place in the light-independent reactions of photosynthesis. Calvin cycle proceeds in three phases: carboxylation, reduction and regeneration.
The cycle produces two molecules of Glyceraldehyde-3-phosphate (G3P) molecule during the reductional step of the cycle. Out of these two molecules, one G3P undergo for the regeneration of RuBP and one G3P undergo for the formation of a glucose molecule.
Thus, option-D is the correct answer.
