If the percent concentration is equal both inside and outside a cell, water does not move into or out of the cell?

miskamm [114]

The Great Plains have a continental climate. Much of the plains experience cold winters and warm summers, with low precipitation and humidity, much wind, and sudden changes in temperature. More rainfall occurs in summer than in winter, except in some of the northwestern parts of the Great Plains.

Hopes this helps!

Semmy [17]

Answer:

4.Antagonistic muscles are muscles that have opposite effects to one another,As one relaxes, the other contracts.

5, This is to move bones in tandem to cause locomotion.As as one contracts, and the other relaxes, the bone is pulled and this shifts the position of the bone to cause locomotion.Note, a muscle cell usually pull in one direction.,

6. it lacks nucleus to have enough space for oxygen carrying molecules(haemoglobin)it has bi-concave shape to squeeze through tinny capillaries to reach tissues and have large surface area for oxygen carriage.They contain Oxygen carrying pigment Haemoglobin.

1.This is a stimulant that increases the rate of excitability by increasing the synaptic connection through increase in amount neurotransmitters, at synaptic junctions

2,This accelerate the rate of ageing.Leading to premature aging.it ,may affect the heart efficiency and the entire cardiovascular system at the long run.

3. After a period of time this may cause liver damage by blocking blood flows to the liver.It may also lead to inhibitory effect of detoxification activities of the liver.This leads to hepatic failure.

7. A state of matter can only be compressed at the gaseous state.it can not be compressed at solid because the inter molecular forces are very strong and the molecules of solids are well compact. Molecules of liquids are not free neither, although their molecular force are weak, But the molecules can not be compressed, since they lack random motion.

8. This is due to the lattice arrangement of water molecules in ice, resulting in lesser density of ice compare to that of water. The lower density of ice makes ice to float when it freezes, however, it is the higher lattice arrangement in ice which makes it expand, compare to other liquids which makes it less dense and therefore floats.

10. This can be caused by the force that pull water through the mains to the pipes.it is measures in bars. Thus 1 bar is equal to the force per unit area lifting water to a height of 10 meters.

9. This is to generate a forward thrust, to overcome the aerodynamic drug.The propeller engine generate a thrust, which ensure a steady speed large enough to overcome the drag

In drosophila, proper anteroposterior and dorsoventral development requires a separate set of maternal effect gene products accu

rosijanka [135]

It is true. In drosophila, distinct sets of maternal impact gene products must accumulate in the proper region of the embryo to ensure proper anteroposterior and dorsoventral development.

<h3>What makes Drosophila unique?</h3>

The use of Drosophila over vertebrate models has many technological advantages;

they are simple and affordable to culture in lab settings,
have a significantly shorter life cycle,
produce huge numbers of externally deposited embryos
may be genetically manipulated in a variety of ways.

<h3>Why is Drosophila referred to be the genetic Cinderella?</h3>

Drosophila, which means "dew loving," is derived from the Greek word drósos.
Fruit flies, or Drosophila melanogaster, are referred to as the genetic Cinderella.
This term was given to them because of their 12-day lifetime, ease of culture, and ability to produce numerous offspring from a single reproduction.

How does cystic fibrosis affect meiosis?

Anna007 [38]

Answer:

The defective CFTR protein changes ion influx and efflux across the body's cell membranes, which ultimately changes the internal environment of these cells. This change contributes to each cell's production of proteins through transcription and translation.
