Neuron
Neuron can be defined as excitable
cell that usually carries, processes and transmit impulses or electrical
signals. Thus, they are known to be basic unit of the nervous system which
includes the spinal cord and brain. However, the signals between s neurons occur
via certain connections called synapses.
Answer:
50% probability of Pp (purple) or pp (white) genotype.
Explanation:
P = purple gene
p = white gene
Punnet squares show the possible genotypes and probabilities of each genotype in the offspring of a cross:
Purple flower genotype (heterozygous) = Pp
White flower genotype = pp
Punnet Square:
![\left[\begin{array}{ccc}&P&p\\p&Pp&pp\\p&Pp&pp\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%26P%26p%5C%5Cp%26Pp%26pp%5C%5Cp%26Pp%26pp%5Cend%7Barray%7D%5Cright%5D)
Potential genotypes for offspring are Pp and pp;
According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;
This means 2 should be purple and 2 white;
Or, there is a 50% chance of having either genotype, of being purple or white.
Answer:
In the animal cell the organelles that is labelled G is mitochondria.
Explanation:
Mitochondria are the membrane bound organelles with inner membranes folded inside which can form finger like structures called cristae. There numbers are more in the cell. They are basically responsible for the production of the energy, hence called as the power house of the cell. They also perform the cellular respiration, which means it takes the nutrients from the cell breaks it and makes energy from it. This energy is used by the cell to carry out various life processes.
Complete question:
Thinking creatively about evolutionary mechanisms, identify at least
two schemes that could generate allelic polymorphism in a population except natural selection that favors heterozygotes.
<u>Select the two correct answers.</u>
-inbreeding among individuals in the population
-purifying selection against mutational variants of alleles in the population
-continuous migration of individuals with new alleles into the population
-mutations that do not severely affect viability and reproductivity
-genetic drift of alleles common in the population
-events leading to genetic bottleneck effect
Answer:
The two events that might favor heterozygotes among the options are
- The Continuous migration of individuals with new alleles into the population
- Mutations that do not severely affect viability and reproductivity. These might favor heterozygous frequencies.
