What is meiotic metaphase I?

Biology
1 answer:
ELEN [110]2 years ago
3 0

Answer:

Definition. The first metaphase of meisosis I encompasses the alignment of paired chromosomes along the center (metaphase plate) of a cell, ensuring that two complete copies of chromosomes are present in the resulting two daughter cells of meiosis I. Metaphase I follows prophase I and precedes anaphase I.

The ecology question above says : A fast swimming strong body fish such as a swimming which is adapted to clear fast and strong
Dafna11 [192]

Correct question:  A fast swimming strong body fish such as a <u>salmon</u> which is adapted to clear fast and strong water current would most likely be found in which aquatic zone? Options in the attached file

Answer:

Source of a river zone

Explanation:

The fishes body is directly correlated with their environment and the pressures they receive from it. Those animals that are used to living in clear waters, with fast currents must be very strong, must have a hydrodynamic torpedo-like body and big and strong caudal fin to propel against the currents. These animals are used to living in water masses such as the source of a river zone.

Rivers belong to lotic environments, characterized by constant moving water.

  • Profundal zone: Sunlight can not reach this zone, so there are no plants. The Water movement is very limited, and in most cases, water is not clear.
  • Littoral zone: Is the transition zone, near the shore, where the light easily reaches the bottom. Usually, there is plenty of vegetation fixated to the bottom.
  • Wetland zone: In general these are calm water, very rich in diversity, and a proper breeding area for a wide variety of fish.
  • Source of a River zone: Rivers flow from higher to lower areas. They originate at the top of the mountains and fastly descend to finally end in a lake or in the sea.

Some species of salmons characterize by living in the sea during sexual maturity, but whenever they need to breed, they go back to the area where they were born. This is in sweet water. They swim in the river until they reach the place where they are going to oviposit. In order to do this, they need to swim against the current. Many times, females die trying to reach this special place.

Some traits do not obey Mendel's law. For example, people with red hair tend to also have pale skin. Why might this be the case?
Misha Larkins [42]

Answer: Polygenic inheritance

Explanation:

Polygenic inheritance is a phenomenon that explains how a character like skin color show a range of more or less continuous variation due to many genes controlling it. And this is unlike Mendel traits that are controlled by single genes.

So, skin color in an individual is expressed as red hair and pale skin.

predict what might happen if the respiratory membrane were instead composed of two layers of stratified squamous epithelium
scoray [572]

If the respiratory membrane is composed of two layers of stratified squamous epithelium, it will mostly contain numerous cell layers because it is its composition of having to be a stratified squamous epithelium. Another thing, the tissue will most likely be a shield for this type of epithelium will serve as a protection against abrasion of which the respiratory membrane will be protected of.
