The correct answer is B. Contact comfort

Explanation:

Studies with Rhesus monkeys were carried out by the psychologists Harry Harlow to study psychological and emotional aspects related to maternal separation and isolation. In this experiment, Harlow used baby monkeys and observed their behavior in different situations that included separating the baby and the mother, providing a fake mother, isolating baby monkeys for a long time and allowing baby monkeys to choose between their mother or food. The results of this experiment showed mother-infant emotional bonds were key for the development and socialization of monkeys, this could be explained as mother monkeys provided contact comfort which supported a positive development and prevailed over food or nourishment.

9. Which structure helps animal cells maintain their shape?
ludmilkaskok [199]

Answer:

<em><u>D. Cytoskeleton</u></em>

Explanation:

It is really none of these answers. The correct answer would be a microtubule which is a component of the cytoskeleton which is in the cytoplasm.

The Cell Walls are only in plant cells so that won't work.  So, A wouldn't work.

Chromosomes are the things that both your parents give you as genes. They have nothing to do with keeping the structure of the cell alright.

Cytoplasm cannot be a answer choice because, the thing is in it but, it doesn't do anything with it. So C wouldn't work either

The correct answer is microtubule however, it is a component of cytoskeleton so therefore, that is your answer.

The absence of which of these will not affect photosynthesis is - oxygen, Carbon dioxide, water, Chlorophyll, light. Give reason
In-s [12.5K]

Answer:

Oxygen

Explanation:

Oxygen is the by product of photolysis during photosynthesis whereby water molecules are split to form protons (H+ ions), electrons and oxygen (by product).

Oxygen is not needed during any of the reactions in photosynthesis and Calvin cycle and will not affect the rate of photosynthesis or possibility of photosynthesis occurring. However, it will affect the process of aerobic respiration instead.

Carbon dioxide is needed in carbon fixation during the Calvin cycle. Without it, 6 carbon sugars cannot be formed.

Water is needed for photolysis to produce protons (maintain the electrochemical gradient) and electrons (to replenish lost electrons)

Chlorophyll are pigments that harvest light energy to excite electrons produced from photolysis of water to be passed down the electron transport chain.

Light is needed as a source of energy to energise the electrons
