Phytoplankton; small cells that use photosynthesis to turn sunlight into food that live near the surface of the ocean. There also responsible for about half of the Earth's primary production. The seasons also affect how well there doing, they need the climate best for them to produce right, changing seasons doesn't nearly affect them as much as climate change though.
Hope this helps, have a BLESSED day! :-)
C.) 45 AND 75............
Pretty sure the correct answer is D
Answer:
<em>A mutation in his offspring</em>
Explanation:
A mutation can be described as any change which occurs in the DNA of an organism. Mutations can be either heritable or non-heritable
If a mutation occurs in the gamete cells of a male, the mutation will be heritable and will occur in his offsprings.
Other options, like option D, is not correct because a mutation in the gamete cells will not cause a mutation in the somatic cells. Gamete cells are the sex cells and hence mutation will arise in the sex cells.
Answer: The chances that the baby will have type O is 25%
Explanation: Both the male and female are heterozygous for type B blood, this means that they both have one dominant allele for type B blood and one recessive allele for type O blood. Remember that in the ABO blood system, The alleles for type A and B are dominant while the allele for type O blood is recessive.
This means that the genotypes of both parents for type B blood is BO.
BO x BO = BB, BO, BO, and OO.
Phenotypically, BB and BO will manifest as type B blood while OO will manifest as type O blood.
From the cross between the two parents, one out of the four offsprings has type O blood, therefore the chances of a child having type O blood is 1/4 x 100 = 25%.
