Complete question:
In one plant, the allele for long stems (L) is dominant; the allele for short stems (l) is recessive. The scientist crossed a heterozygous, long-stemmed plant with a short-stemmed plant. Which of these shows the expected results of this cross?
- 50% long-stemmed plants and 50% short-stemmed plants
-
75% long-stemmed plants and 25% short-stemmed plants
-
100% long-stemmed plants
-
100% short-stemmed plants
Answer:
- 50% long-stemmed plants and 50% short-stemmed plants
Explanation:
Due to technical problems, you will find the complete explanation in the attached file.
Answer:
True
Explanation:
With the increase in altitude, the atmospheric pressure and amount of oxygen decreases.
When a person moves to high altitude, they adapt to the lack of oxygen by increasing their red blood count and the process is called acclimatization. The lack of oxygen is monitored by the peripheral chemoreceptors, that increases ventilation. The body starts producing red blood cells (RBC) in order to resist the lower oxygen saturation in blood in high altitudes.
That is why, people living in high altitudes have higher red blood cells count in comparison to people living in cities or plain areas.
Hence, the given statement is true.
A zygote is the product of fertilization. The diploid zygotes of the four organisms seen here all underwent mitosis and differentiation in order to produce the four very different embryos. The differentiation of cells during embryogenesis is the key to cell, tissue, organ, and organism identity. Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells by mitosis, triggering the beginning of embryonic differentiation. <span />
