Diffuse reflection would be the answer.
<span>The correct option is C. Erosion is the process by which the earth surface get worn down. It involves the removal of soil, rocks or dissolved material from one location and its transportation to another location. Erosion can be caused by water, wind and glacier.</span>
Answer:
The crab has just molted and the new exoskeleton has not yet hardened.
Explanation:
Crabs have an exoskeleton or shell which protects and supports them. From time to time crabs molt i.e. they discard the old exoskeleton and begin forming a new one. This process is a part of their normal growth. Soft-shell crabs had recently undergone molting and the new shell had just started to form. Hence, it has not hardened completely and is comparatively soft. Soft-shell crabs are in popular demand because it is easier to remove the soft shell and access the meat as compared to the normal crab.
Answer:
<h2>Dihybrid cross involves crossing between two traits. Independent assortment is also explained using a dihybrid cross.</h2>
Explanation:
To obtain a phenotypic ration of 1:1:1:1 one of the parent must be heterozygous for both the trait and other parent must be homozygous recessive for both the trait.
If the long winged <em>Drosophila</em> with gray body is dominant then, it is represented by these genotype- LLGG, LlGG, LlGg and LLGg. Short and black <em>Drosophila</em> is considered as recessive (llgg)
Different crosses were carried to obtain a phenotypic ratio of 1:1:1:1.
So, if we cross LlGg with llgg we obtain a phenotypic ratio of 1:1:1:1
we obtain <em>Drosophila</em> which are
Long gray (4)
Long black (4)
Short gray (4)
Short black (4)
So, ratio comes out to be 1:1:1:1
Answer:
All the possible alleles for a gene with multiple alleles cannot be expressed by single individual
Explanation:
Gene pool refers to the sum total of all the alleles of all the genes which are present in a population. Human beings are diploid organisms. One individual can have only two possible alleles for a gene. A gene can have two or more than two alleles. Since all the possible alleles for a gene with multiple alleles cannot be expressed by single individual, a gene pool cannot be made of one individual.
