Answer:
24 chromosomes
Explanation:
The Human Genome Is Composed of 24 Different Types of DNA Molecules. Human DNA is packaged into physically separate units called chromosomes.
Ans. Option (IV).
Mosses can be defined as non-vascular, flowerless plants that are found in shady or damp regions and reproduce via haploid spores. During reproduction in moss, haploid male gametes or spores are released into surrounding environment that fuse with female spores to form zygote that develop into mature sporophyte.
Angiosperms are vascular, flowering plants that reproduce by seeds. During reproduction in angiosperms, haploid male gametes or pollen grains are released into surrounding environment that fuse with female gametes or eggs to form zygote that develop into seed.
Thus, the correct answer is option (IV).
Areas near continents where freshwater rivers enter the ocean. The ocean IS salt water.
Answer:
Hypothalamus
Explanation:
Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C.
Answer:
The odd is zero.
Explanation:
Assuming the Huntington disease allele is represent by b. Nomal allele will be B which is the alternate form.
The genotype of the 25 years old woman will be Bb, since she heterozygote.
The genotype of the husband will be BB, since he's free from the trait.
Crossing both genotypes:
Bb x BB = BB, BB, Bb and Bb.
The genotypes of the offspring will be either BB or Bb. They either free from the trait or heterozygote.
<em>Hence, the odds that the couple will have a child with the disorder is 0. They can only produce heterozygotes or totally normal children.</em>
