The study of lithospheric plate movement and associated activities is known as Plate tectonics. It mainly deals with the study how the rigid lithospheric plates move over the underlying mantle.
This statement is true.
Some scientist refer to the adrenal medulla as a 'misplaced' sympathetic ganglion because <span>embryologically, they arise from the same tissue. As the name itself says, the adrenal medulla is located within the adrenal gland, and represents its central part. </span>
Answer:
the "second law of Mendel", or principle of independent distribution, states that during the formation of gametes, each pair of alleles segregates independently of the other pairs.
Explanation:
Mendel's second Law is also known as the Law of Segregation, also as the Law of Equitable Separation, and also as the Law of Disjunction of the Alleles. This Second Law of Mendel is fulfilled in the second filial generation, that is to say, from the parents to the first generation, the First Law of Mendel is fulfilled, and after the children of the first generation this Second Law of Mendel is fulfilled.
This 2nd Law of Mendel, speaks of the separation of the alleles in each of the crossing between the members of the first generation, who would now become parental of the second generation, for the formation of a new child gamete with certain characteristics.
Since each allele is separated to constitute features that do not belong to the first filial generation, but to that of the parents. That is to say that many of the most obvious features in the recessive allele would be present when a generation leaps. All this in relative proportion to the number of individuals in the second subsidiary generation.
Answer:
The individual is a male. Explanation: In mammals, sex is determined by a pair of sexual chromosomes.
The finches on the Galapagos Islands are a good example of adaptation because they all trace their ancestry into a small group of finches that inhabited these islands, but diversified in accordance to the environment. On the Galapagos Islands, there are finches that have numerous types of different beak shapes and sizes, despite them all being derived from a single group of finches that had the same characteristics. The reason for this is that once they got to these islands, there were multiple niches int the food chain that were free for taking. Some finches started to feed on plants, some on seeds, some became insect-eaters etc. Every food type needs special adaptation so that the finches can eat it more easily, or even be able to get to its nutritional part, thus their beaks started to change in accordance to their food preference.
