Answer: Cumulative inherited change in a population of organisms through time leading to the appearance of new forms
Explanation:
Answer: it is D
Explanation:
B) X or Y chromosomes, inherited from your mother.
C) two of the 22 pairs of chromosomes your inherited.
D) chromosomes from your mother and X from your father.
Answer:
The correct answer would be option A.
In humans, the gender of a child is mainly determined by the sex chromosome inherited from the father.
It is because human females are homozygous (XX) in terms of sex chromosome. So, their gamete will always contain an X chromosome.
In contrast, human males are heterozygous, that is, they contain XY as sex chromosome. Thus, they will produce two types of gametes of which one would contain X and the other one would contain Y.
When the male gamete containing X chromosome fuse with female gamete, the offspring produce would be a girl and when the male gamete containing Y chromosome fuse with female gamete, the offspring produce would be a boy.
B. The lithosphere is denser than the asthenosphere.
C. The asthenosphere is denser than the lithosphere.
D. The lithosphere has the same density as the core.
Answer:
A
Explanation:
Isostatic equilibrium is used to state why some regions of the lithosphere have greater elevation than others. The crust ‘floats’on the‘liquid’ mantle below and different regions of the crust submerge into the mantle differentially depending on their local densities or weight. Heavier regions such as in mountainous region (like the Himalayas) are sunken deeper into the mantle that other regions. Every local region has its own local isostatic equilibrium.
Answer:
The correct option is Option C
i.e. Asthenosphere is denser than lithosphere.
Explanation:
Asthenosphere is the layer situated below the lithosphere.
Theory of isostasy says that the layers above the other layer must have lesser density. This has two explanations. Firstly, if its not hold, then the denser above layer would sink below the less denser bottom layer. Secondly, as we go inwards, the pressure increases. This leads to the lower layers have greater density. So, as Asthenosphere is situated below the lithosphere, it has higher density.
Answer:Equilibration buffer provides a condition to ensure that the target molecules interact effectively with the ligand and are retained by the affinity medium as all other molecules wash through the column.So the buffer pH and ionic strength at optimal condition are responsible for this ligand-molecule interaction.I hope this will help you.
B. A decrease in gene flow
C. An increase in gene flow
D. an increase in genetic drift
Reproductive isolation within a species causes is an increase in gene flow. The correct option is C.
Reproduction isolation is a mechanism constituted by some factors like behavior, physiological process, etc. by which the species does not reproduce with other species.
Gene flow is the flow of genes in forward generations, and reproduction isolation increase the gene flow within species.
Thus, option C. An increase in gene flow is correct.
