DNA ligase is the enzyme that repair irregularities and breaks in the back bone of double stranded DNA. The enzyme function by sealing the repair in the DNA, it seals recombination fragments and it connects okazaki fragments during replication of DNA.
If a mutation reduce the amount of ligase, all the functions of the ligase enzyme listed above will be affected negatively.
Adaptations help the survival of a species as "It increases the biodiversity of the species".
<u>Answer:</u> Option C
<u>Explanation:</u>
The phenomenon that support the organisms to find similar and favourable environment to acquire food, build home, satisfy with weather, feel safe and attract mates to produce more offspring in order to improve evolutionary fitness is called as an "Adaptation".
The three main forms of adaptations are behavioural, structural, and physiological adaptations that are based on the way how genetic variation get communicated. Many species have all those types of combinations. For an instance, behavioural adaptations are bird's calling and migration.
Answer:
To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells.
Explanation:
1) 5% of saturated fat in one serving
2) 2 grams of dietary fibre
3) 750 calories
4) 9%
5) no
Explanation:
From the chart it is given that 1 serving gives 250 calories of energy while 1 container has 3 servings.
The dietary fibre in 250 calorie serving is 2 grams so on consuming 1 serving you get 2 grams of dietary fibre. It provides bulk to the roughage.
The entire container will give
3*250
= 750 calories in entire container.
If entire container consumed then ( 2grams amounts to 3%)
so three servings, 3*3
= 9%
No vitamin C is found in the serving.
