Answer:
well animals have better feeling in tempeture
Explanation:
so basically if you have a fish in a bag in a hot tank and we cant feel it its because some things need to actually get hot enough or cold enough forus to feel the tempeture so basically animals have better feeling for the heat or the cold than humans
Answer:
Due to different grouping style
Explanation:
There are two modes of classifying an organism due to which two different cladogram are produced-
A) When the organisms are grouped together on the basis of similarities shared by them – Such species are named based on the name of older species and the newly discovered species sharing similar traits are kept under older species thereby dropping its own name.
B) In the second method, the minute differences are observed in species to group them into several branches arising from one parent organism.
Answer:
a) epigenetic change.
Explanation:
Epigenetic is referred to changes BESIDES the changes in the genetic changes. It means, not related to mutations but to chemical changes such as methylation, acetylation, ubiquitylation, phosphorylation, that can interfere with the genetic expression. Chromatin modification is another way of epigenetic change.
The randomness in the alignment of recombined chromosomes at the metaphase plate, coupled with the crossing over events between nonsister chromatids, are responsible for much of the genetic variation in the offspring. To clarify this further, remember that the homologous chromosomes of a sexually reproducing organism are originally inherited as two separate sets, one from each parent. Using humans as an example, one set of 23 chromosomes is present in the egg donated by the mother. The father provides the other set of 23 chromosomes in the sperm that fertilizes the egg. Every cell of the multicellular offspring has copies of the original two sets of homologous chromosomes. In prophase I of meiosis, the homologous chromosomes form the tetrads. In metaphase I, these pairs line up at the midway point between the two poles of the cell to form the metaphase plate. Because there is an equal chance that a microtubule fiber will encounter a maternally or paternally inherited chromosome, the arrangement of the tetrads at the metaphase plate is random. Thus, any maternally inherited chromosome may face either pole. Likewise, any paternally inherited chromosome may also face either pole. The orientation of each tetrad is independent of the orientation of the other 22 tetrads.
Explanation:
The crust is not magnetic near the ocean ridges
