Besides producing sugar for itself a plant also needs to absorb nitrogen to build proteins, salts to make concentration gradients and potassium to make enzymes.
<u>Explanation:</u>
Plant sugar is glucose and plants produce it by the process of photosynthesis making use of energy from sunlight, carbon dioxide absorbed from the atmosphere and the presence of chlorophyll in its parts. Plants also require components other than this. Nitrogen is essential to make proteins and it cannot be directly absorbed from the atmosphere but has to be absorbed from the soil.
Potassium is an essential component which is absorbed from the soil. It facilitates the activation of enzymes which play a crucial role in plant metabolism. When plants lack potassium they won’t have enough energy for proper growth and will have poorly formed roots and weak stems.
Answer:
I believe the correct answer is homeostasis. When your blood sugar is too high, your pancreas secretes insulin. When your blood sugar is too low, your pancreas secretes glucagon to regulate it.
Answer;
-Skin cells do not need crystallin for their function.
-Skin cells have the crystallin gene but do not express it.
Explanation;
-The crystallin proteins are water-soluble structural proteins that occur in high concentration in the cytoplasm of eye lens fibre cells. It has also been identified in other places such as the heart, and in aggressive breast cancer tumors.
-The main function of crystallins at least in the lens of the eye is probably to increase the refractive index while not obstructing light. The skin cell does not make crystallin protein because the skin cells do not need crystallin for their function and also they have the crystallin gene but do not express it.
Answer:
The complementary DNA sequence of each triplet is as follows:
ATG - TAC
ATC - TAG
GCA - CGT
AGT - TCA
AGC - TCG
GCC - CGG
GAT - CTA
AAG - TTC
TTG - AAC
CAG - GTC
TAG - ATC
Explanation:
A double-stranded DNA molecule is made up of two strands of DNA whose sequence are complementary to one another and linked by hydrogen bonds. According to the complementary base pairing rule as postulated by Chargaff, Adenine base will always hydrogen pair with Thymine base while Guanine base will always hydrogen pair with Cytosine base i.e. A-T, G-C
Based on the above explanation, the following triplets of DNA will have the following complementary sequences:
ATG - TAC
ATC - TAG
GCA - CGT
AGT - TCA
AGC - TCG
GCC - CGG
GAT - CTA
AAG - TTC
TTG - AAC
CAG - GTC
TAG - ATC
