MakcuM [25]3 years ago

The monozygotic twins develop from the same fertilised egg. Hence the genetic composition or the make of both the twins are same. The differences in the height, weight, behaviour, and complexion of the twins exist not because of the underlying genetics but because of the environmental factors affecting the genes' activity.

The regulatory markers (chemical markers like the presence of methyl or acetyl group on the nucleotides) present on the identical genes present in both the twins differ. This is the epigenome of the twins. Epigenome is influenced by several external factors and affects the amount of gene products based on the regulatory markers over the gene.

This is an active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.
faltersainse [42]

Answer:

Primary active transport

Explanation:

Primary active transport is the transport in which molecules are moved against their gradient, with direct use of ATP as an energy source. Na/K pump  is an example  of primary active transport: Na ions are transported out of cell, K ions are moved into the cell. This pumps maintain concentrations of those ions and also creates voltage across the cell membrane, which can be used for the secondary active transport of other molecules (e.g. glucose).

How does a slow moving front differ from a fast moving front?
sashaice [31]
Fast-moving cold fronts force the warm air ahead of them to rise more quickly than slow movers. The clouds and rain are mostly along the front or ahead of it, and heavy rain or thunderstorms are common. A slow-moving front lifts the warm air more gradually; the rain is less intense, and the clouds form along and *behind* the surface cold front.

2. Which of the following may affect a passenger's safety during a collision? Select all
devlian [24]

Answer: All of them seem to apply.

Explanation:

A., Its important to know if your car that is being collided is a small car or big truck, as they will end up effecting who gets hurt the most.

B., Same thing as A. but with the other vehicle.

C., The velocity matters a lot with a collision, since a slow crash won't have as much damage as a car going fast and hitting someone. Also it won't be as likely to be fatal if the car crashing into you is going slow.

D., This is the only one I'm not too sure on, but it seems like how fast the car can accelerate once collided with would be a big factor on whether it would come to a halt or skid across the road.
