Answer:

Stomata are small pores present on the surface of leaves and stem in plants. There are specialized cells named as gaurd cells which facilitates the opening and closing of stomatal pores. The two main functions of stomata are:

1. Gaseous exchange : It allows the uptake of carbon dioxide which is an important ingredient for conducting photosynthesis and release of oxygen to the external environment which is a product of photosynthesis.

2. Prevents the loss of water: Stomata remains closed during dry and warm external environmental conditions so as to prevent water loss.

In ordinary plants if stomata remains closed than there will be no gaseous exchange therefore, photosynthesis will not take place in these plants. Closed stomata will also prevent loss of water in dry and warm external conditions.

Which statement below describes a feature that is shared between kinesin and dynein? a. Both proteins "walk" towards the (+) end

spin [16.1K]

Answer:

C)Both proteins bind ATP and F-actin

*C option is not mentioned* there is a flaw in the question

Explanation:

Two families of motor proteins, kinesin and dynein, transport membrane-bounded vesicles, proteins, and organelles along microtubules. Nearly all kinesins move cargo toward the (+) end of microtubules (anterograde transport), whereas dyneins transport cargo toward the (−) end (retrograde transport).While

both the protiens have globular ATP-binding heads that function as the motor domain and interact with the microtubules.

Some micronutrients, such as vitamins e and c, can function as antioxidants in that they are able to neutralize free radicals. Radical are highly unstable molecules produced in our body when we are exposed to toxins. Vitamins C and E, carotenoids (including beta-carotene), and the mineral selenium are all powerful antioxidants found in food.

Put the following events in the correct order:

Wewaii [24]

Answer:

Explanation:

c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.

a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.

b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.

The process of deoxyribonucleic acod starts with replication to transcription and translation.

Replication involves the formation of a complementary base from a old or template DNA Strand this then serve as a template for transcription.

transcription involves the coping of information on the DNA to an intermediate mRNA ( messanger ribonucleic acid) in the nucleus which then move from the nucleus to ribosome in the cytoplasm where translation occurs.

Translation is the conversion of the information on the mRNA to an amino acid with the help of enzyme transferse ribonucleic acid(tRNA).

Hence the arrangement is from C ---- A-----B.
