The correct answer is: E) cleavage furrow formation and cytokinesis
Cytochalasin B (cytos-cell and chalasis-relaxation) is a molecule which inhibit network formation by actin filaments by blocking monomer addition. As a result, itshortens actin filaments. This molecule is involved in cytoplasmic division where it blocks the formation of contractile microfilaments. One of the microfilament’s function includes cytokinesis and formation of cleavage furrow so these functions are affected by cytochalasin B.
The other guy is right, B is the answer now hurry and get that test prep done
Answer:
Scientists are studying a group of ant colonies in the Arizona desert. Which question about the ants can be answered scientifically?
Explanation:
The correct answer will be option- Does the amount of sunlight in a day affect how much food the ants eat that day.
Explanation:
A scientific method is a systematic approach to understand and explain any natural phenomenon in nature. The scientific method involves making, ask a scientific question, do background research and propose a hypothesis which could be tested to produce a real answer to the scientific questions.
In the given question, the scientist wants to study the ants in the desert through scientific method. The possible question that could be answered will be the how the amount of light can affect the quantity of food consumed by ants as the amount of food can be studied through the experiments by proposing a hypothesis.
Thus, the selected option is the correct answer.
Answer:
Concentration gradient
Explanation:
Concentration gradient of the ions across the membrane generates the membrane resting potential.
Concentration gradient means that there is unequal distribution of the ions on different sides of membrane. For example, the concentration of K ions is much higher within the cell then out of the cell. Opposite is with the Na ions. When ions move from the area of their higher concentration to the are with the lower concentration, we say they move down the gradient or diffuse (no energy required). On the other hand, movement of ions against their gradient means that this process requires energy and involves protein pumps.
