The correct option is this: THE CELLS SHRIVELS AS WATER MOVES OUT OF THEM.
Drinking too much water makes the concentration of sodium inside the cell to be lowered compared to the concentration of sodium salt outside of the cells. Because of this, water will flow out of the cell into the surrounding medium and the cell will shrink up. Water usually flow across a semi permeable membrane in the direction where there is high concentration of solutes. Water volume remains the same in both side of a semi permeable membrane if the solution is isotonic, that is the concentration of salts on both side of the membrane is the same. In a situation where the surrounding medium is not isotonic, water flow to the region, where the concentration of salt is higher.
C. Cells shrivel as water moves out of them.
Capillaries; veins; arteries
Capillaries allow materials to be exchanged between the blood and tissues, veins carry blood towards the heart, and arteries carry blood away from the heart.
Capillaries are small blood vessels through which molecules such as oxygen and glucose enter the cells.
Veins are tubes or blood vessels that transport blood toward the heart. Veins mostly transport deoxygenated blood towards the heart except the pulmonary and umbilical veins, which transports oxygenated blood toward heart.
Arteries are blood vessels that transport blood away from the heart to other parts of the body. Arteries have elastic walls and they are stronger and thicker than veins.
humans and fish evolved from insects
B.
different species synthesize the same proteins
C.
insects, fish, and humans express the same genes
D.
different species share components of the genetic code
The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code
Explanation:
Evaluating the other options given
A.humans and fish evolved from insects-This option is incorrect as human and fish did not have a common ancestors.
B.different species synthesize the same proteins:No this statement also is not the correct option
C.insects, fish, and humans express the same genes-The expressed genes cannot be same for different species
Hence the correct answer is
The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code(As the genetic code is said to be universal
2 Nature created the first cell.
3 The first cell originated spontaneously.
4 This postulate of cell theory is false.
Answer:
option 2 and 3 are seems to be correct.
Explanation:
according to our studies the options and 3 are seems to bee correct because the first cell was created by nature not by man or any other organism and the term spontaneously also look to be true. so my answer is that options 2 and 3 are correct.
caterpillars and grasshoppers and beetles
