trees do not fix N2 from air they fix oxygen with the help of N2 fixing bacteria . so trees do not fix N2
The respiratory system always needs iron. The red blood cells are in charge of the transport of O2. They need iron to do this.
Hope this helps! :)
The Gap 2(G2) stage of Interphase
Explanation:
In a eukaryotic cell, the cell cycle refers to both -cell growth and cell division - leading to the production of identical daughter cells. The cell cycle is basically divided into interphase (I) and mitosis (M).
The interphase, during which the cell grows and replicates its DNA takes place by the following stages – Gap 1 (G1), Synthesis (S), Gap 2(G2).
The cells grow and increase in size during the G1 period.
The G2 phase or the second gap phase the cell utilizes energy and produces necessary proteins for undergoing chromosome manipulation and other organelles and prepares the cell for mitotic cell division.
DNA replication mainly takes place in the Synthesis or the S stage of interphase with each of the chromosomes (46) is replicated.
Due to this DNA replication in the S stage, its content is doubled (4-N DNA content) when it enters the G2 stage and all the DNA is found within a single nucleus.
The correct answer is - C) 5:35 PM Friday.
The low tides occur twice in a lunar day, thus they are diurnal. The low tides appear when the Moon is between that point of the planet and the opposite of that point of the planet, thus in between, which is happening twice, on opposite parts of the planet.
Since the lunar day lasts for 24 h 50 m, we should just divide it in two, thus get 12 h 25 m. Than we should add the 12 h 25 to the time when one of the low tides appeared, which is 5:10 AM, so we will get 5:35 PM.
The low tides appear because the Moon is pulling the water upwards with its gravitational pull above the place where it is, so the side parts of the planet have their waters dragged away,thus resulting in the retreating of the water, known as low tide.
The cuticle is the most exterior layer of arthropods' tegument, and its principal function is to protect the body and avoid dehydration. Option C is correct. Cuticle.
<h3>
What is the cuticle?</h3>
The cuticle is the most exterior layer of arthropods' tegument. It is secreted by the epidermis and develops right over it.
It is composed of two main layers,
- epicuticle ⇒ outermost layer
The cuticle is mainly made of chitin, and its function is to protect the organism's body and avoid dehydration.
Because it avoids dehydration it is believed that arthropods had such an evolutive and adaptative successful in their transition from water to the land.
The cuticle also provides support to the body and a muscle attachment surface.
The correct option is C. Cuticle
A _<u>Cuticle</u>_ is a hard outside covering that is used for protection and prevents the inner body area from drying out.
