Answer:
D. Aa
Explanation:
Given:
Jill (mother) is heterozygous for gene A --------- i.e Jill = Aa
Jack (father) who is homozygous recessive for gene A-------- i.e Jack = aa
Now if both cross and fertilization occurs, we have:
A a
a Aa aa
a Aa aa
The offsprings are (Aa, Aa, aa, aa)
Nondsijunction is the inability of homologous chromosomes to seperate properly during cell division. Now, we were told that this fertilization undergone nondisjunction in meiosis 1. Hence, both homologous chromosome move into the same daughter cells instead of different daughter cells because separation of homologous chromosome does not occur properly.
Therefore the result of these fertilization of a normal haploid sperm with an egg that had undergone nondisjunction in meiosis yields offspring with genotype Aa of their Mother (Jill).
D. Chromosomes as mitosis is essentially asexual reproduction and the offspring is the same as the parent cell
Answer:
The only possible answer is D, which states that the population will reach 5000 and after that the growth will stabilise (exactly what would hapen in a logistic growth).
Hope This Helps! Have A Nice Day!!
For the answer to the question above, there is no such thing as a non-living organism. Because organisms are only a term for living things.
1. Cellular structure: all living organisms generally have a cellular structure i.e., they are made up of one or more cells.
<span>The protoplasm is the physical basis of life. </span>
<span>There is no such fundamental and structural unit called cell in non-living things. </span>
<span>2. metabolism : The various life processes taking place within the body of an organism is collectively termed metabolism. The metabolic processes can occur only in living organisms and not in nonliving things. </span>
<span>3. growth, repair and death : Growth consists of the living organism absorbing materials entirely different from those that make up its body and convert them into body building substances. Growth in non-living substances such as crystal is at the cost of material similar to that of which it consists. Same substance is added without conversion. </span>
<span>The growth is permanent, irreversible process in living organisms but can be reversed in non-living things. </span>
<span>Growth is different in different parts of the body of an organism. Growth is uniform throughout in the non-living things. </span>
<span>Respiration, nutrition,excretion, movement,irritability, reproduction, life span, death, evolvability are other properties of a living organism.</span>
Answer:
The correct answer is option A, that is, cotransport proteins.
Explanation:
The variable that possesses the tendency to mediate energy based on chemical potential is termed as an electrochemical gradient. The electrochemical gradient is differentiated into two parts, that is, electrical gradient and chemical gradient. Both these forms of gradient take place over the surface of a membrane.
The movement of the majority of the ions takes place by the phenomenon of electrochemical gradients, of which some are found on the surface of the membrane and function as electrogenic pumps. While the gradients of some of the ions are mostly accounted for by the co-transport proteins, as these proteins take part in the movement of ions or molecules through a plasma membrane that involves concentration gradient based on the kind of molecules and movement.
