What type of photoreceptor cell allows us to see gray tones in dim light, and provides our peripheral vision

Biology
1 answer:
Andru [333]3 years ago
3 0

Answer:

Rods.

Explanation:

There are two types of photoreceptor cells, the cones, and the rods.

The cones adapt our vision to bright light and allow us to see colors. On the other hand, rods photoreceptors make us see in the dark and do not perceive many colors; that is why we can not distinguish colors in the dark. Also, they provide peripheral vision since they are on the external edges of the retina.

Processes such as changes in orbital geometry or volcanic eruptions have clearly affected climate in the past, and these explain
docker41 [41]

Answer:

TRUE

Explanation:

There has been a constant increase in the earth's global surface temperature. This global rise in temperature is due to the increasing number of volcanic eruptions on earth's surface, changes in the orbital geometry as well as due to the introduction of the industrial revolution, that has been taking place on earth for the last 200 years.

The eruption of volcanoes leads to the release of a large number of pyroclastic materials and greenhouse gases and volcanic gases such as CO₂, SO₂, H₂O, H₂S and many other gases, which is harmful to the atmosphere. This leads to an increasing amount of temperature, resulting in the melting of the glaciers in the polar region.

Over this long time, plate motions have rapidly taken place, due to which the volcanoes were formed and erupted near the convergent and the divergent plate boundaries.

Thus, the above-given statement is true.

saw5 [17]

Answer:

The correct answer is A    DNA  is replicated before mitosis begins

Explanation:

DNA replication is one of the most significant event of a cell cycle. .DNA replication occur in the S phase or synthesis phase of the cell cycle.

       DNA is replicated once per cycle to maintain to normal chromosome number in daughter cells.

     DNA is replicated to form two new DNA molecules which are then equally distributed in each daughter cell during the mitosis phase.

What about cytokinesis
Nady [450]

Answer:

Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. ... Cytokinesis performs an essential process to separate the cell in half and ensure that one nucleus ends up in each daughter cell. Cytokinesis is the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis.
