Answer:
<h2>Sheep B
</h2>
Explanation:
As given;
Step 1: The nucleus was removed from the egg which was unfertilized and,
which is taken from sheep A, means that the egg was from sheep A.
Step 2 : The nucleus of a body cell which is taken from sheep B was then
inserted into this unfertilized egg which is taken from sheep A. Now the egg contain nucleus of sheep B.
Step 3 : The resulting cell containing nucleus of sheep B was then implanted into the uterus of
sheep C.
Step 4 : finally Sheep C gave birth to a sheep named sheep D.
Sheep B would be most genetically similar to sheep D, because the nucleus was taken from sheep B, and the sheep D is the new born which is formed from the nucleus of sheep B.
Answer:
When CO2 is breathed into the lungs, it dissolves in the water there, diffuses across the alveolar-capillary membrane, and enters the bloodstream. As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH.
1. Gametophyte
2. Gametes
3. Zygote
4. Sporophyte
<h3><u>Explanation</u>:</h3>
The life cycle of plants are very interesting in nature. The plant body that we see is the sporophyte. The sporophyte plant has the flowers which contain the Pollen mother cell and embryo sac which are the gametophytes.
These gametophytes produce the cells that are gametes which are pollen and ovule respectively. These grains fuse to form fertilization and zygote. The zygote marks the starting of the sporophytic generation.
The sporophytic generation is diploid and the gametophytic generation is haploid in nature.
