Answer:

A and T occur in similar proportions.

G and C occur in similar proportions.

Explanation:

There are four nitrogenous bases that form integral part of DNA, these are Adenine (A), Guanine (G), Thymine (T) and Cytosine (C). Due to specific base pairing between these bases, (Adenine is always linked to Thymine through two double bonds and Cytosine is always linked to Guanine through three double bonds), it is estimated that A and T occur in similar proportions. while G and C occur in similar proportions. <em>This was proposed by Chargiff for the first time and now it is considered to be as Chargiff rule. </em>You can see chart in attached image to know that how equal the ratios are found experimentally in different living organisms.

Answer:

HOPE IT HELP

Explanation:

On the graph in plato the y axis starts on 8, so that is our initial height. the graph starts to go lower to ground level until it reaches the 12 on the x axis, this is where the skateboarders would meet ground level on the ramp, and obviously the graph is all positive numbers so the start of the ramp would be on the left edge.

Which genetic mutation can be passed to the offspring?

Kitty [74]

Answer:

A gamete containing an extra chromosome is formed.

Explanation:

Geminal mutations may result in the production of mutant gametes. If such gametes fuse with those from another individual of the opposite sex to form a zygote, the mutation is transmitted to the progeny. A trisomy gamete containing an extra chromosome would transmit the mutation to the offspring after fertilization.

During the action potential of a neuron, which ion is primarily crossing the membrane during the depolarization phase, and in wh

iragen [17]

The answer is Na + is entering the cell and the K + is leaving, during the depolarization phase of the action potential open Na + channels allow Na + ions to diffuse into the cell. This inward movement of positive charge makes the membrane potential more positive. The depolarization phase is a positive response sequence where open Na + channels cause depolarization which in re-occurrence causes more voltage gated Na+ channels to open.
