Answer:
True, by active transport
Explanation:
The influx and efflux of molecules through the cell membrane depend on the concentration gradient.
When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.
When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.
In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
Siamogale melilutra is an extinct species of giant otter from the late Miocene from Yunnan province, China.
I think all the mice had brown fur due to epistasis
Explanation:
The expected results would be 50% black and 50% brown and the ratio could be 2:2. But, if epistasis occurred and the brown fur gene overshadowed the black fur gene, then all the offspring could have brown fur.
Answer:
The correct answer is- restriction enzyme
Explanation:
Restriction enzymes are also known as restriction endonuclease which is used in the recombinant DNA technology because they have property of recognizing and cutting a specific DNA sequence.
Every restriction enzyme is different and different restriction enzymes recognize different sequences in DNA and cut them. Restriction enzymes are divided into 4 types of classes, type I, II, III, IV.
These different types of restriction enzymes cut different specific nucleotide sequence. Therefore the correct answer is restriction enzymes.
