A student wanted to see if covering a leaf in foil would stop it from producing starch. Why should the student put the plant in

a dark cupboard for 48 hours before returning it to the light and starting the experiment?
1. To make the results reliable
2. So that the plant would photosynthesise faster when returned to the light
3. So that any starch already in the leaf was used up by the plant
4. He did that simply

Answer:

Putting the plant in dark for 48 hours would stop the process of photosynthesis as light is required for it. Photosynthesis produces organic sugars which are stored in form of starch in plants. The absence of photosynthesis would lead to the consumption of all stored starch making the leaf starchless. The correct answer is option D.

mihalych1998 [28]

Answer:

Option-A

Explanation:

RhoA is a protein which belongs to the Rho GTPase family proteins and related Ras superfamily. The Rho A protein is involved in the cell division before the cytokinesis as they are involved in the formation of cytokinesis structures like the actin-myosin rings and the contractile ring formation.

In the given question, if the drug inhibits the activity of RhoA, therefore, cytokinesis will be affected and the cell will complete all the stages of Mitosis except cytokinesis. The cells will be mostly observed in the telophase as cytokinesis will take place after that.

Thus, Option-A is correct.

what percentage of the energy flowing through primary producers is ultimately transferred to secondary consumers?
Finger [1]
<span>Energy transfer is the transmission of food energy from organism to the next which is illustrated as the food chain. Normally and typically, the autotrophs are the photosynthetic organisms that primary makes food for itself and for other organisms. </span><span>Hypothetically, we can assume that about 6000 kilocalories per square meter per year these autotrophs can collect and store energy.</span><span> Primary consumers like omnivores such as deer, cow, birds and etc. receive almost 10% as much from these autotrophs. </span><span>Secondary consumers receive for as much as 1% of the total energy that was from the autotrophs.   </span>
