What genes each parent had for that trait.
Example: In peas, the trait for green peas is dominant (G) and the trait for yellow peas (g) is recessive. If you want the offspring to definitely be yellow, then both parents have to be yellow, with the allele frequency of gg. If both parents were carriers of the yellow gene, but were green (Gg), then there is a 25% chance of having yellow offspring, the rest being green. If one parent is a carrier (Gg) and the other is yellow (gg), then there is a 50% chance of having either yellow or green offspring. If one parent is homozygous (two alleles of the same gene) dominant, then no matter who that parent is paired with, then the offspring will definitely be green.
This can all be figured out through punnett squares
<span>Transmitted via neurotransmitters. There is a gap between two neurons. This place where the axon meets with dendrite is callde synapse. Neurotransmitters which are chemicals help transmit the signals from axon to dentrite. Calcium ions play major role in this process.</span>
Answer:
Option (b) When dehydrated, a camel stores nitrogenous wastes in its tissues to conserve water.
Explanation:
The camel has good a hump on its back that helps with water storage. This is also made up of a water soluble fatty substance and fats. The water regulation is also controlled by the nephron which is an integral part of the kidney. The nephron has the Loop of Henle that regulates the retention of the water in the body. When there is no water, the potential of the ions force the water back into the kidneys so that the cells do not get disturbed. The nitrogenous wastes are expelled out as soon as possible because they form ammonium salts that may disturb the cell metabolism.
Hence, option (b) is not true.
Answer:
Meiosis
Explanation:
This occurs during fertilisation when a male and female gamete fuse to form a single cell.
It isn't mitosis because, when two cells are produced, they are identical to the parent cell, thus called daughter cells and remains to have a diploid number of chromosomes.
Everglades National Park is a wetlands preserve on the southern tip of the U.S. state of Florida. It is made up of coastal mangroves, sawgrass marshes and pine flat woods that are home to hundreds of animal species. The water of this wetlands is polluted. So, there is a need of improving and protecting water quality.
One very effective way to reduce water pollution in the Everglades National Park is to clean the water, take out the fertilizer and build marshes that are designed to clean the water as it flows.
