NADPH is the reduced form of NADP+. This simply means that NADPH has an extra hydrogen ion.
NADPH is formed when upon the reduction of NADP+ . NADP stands for nicotine amide dinucleotide phosphate. It is a coenzyme that is involved in a wide range of anabolic reactions.
During the synthesis of carbohydrates in plants, NADPH acts as a reducing agent, likewise in the synthesis of nucleic acids and lipids.
As a reduced compound, NADPH becomes a molecule with high energy thus being especially useful in driving the Calvin cycle.
Answer:
The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure.

Answer: the rate of pollination of flower, in a field next to a pond with no fish, will DECREASE.
Explanation:
POLLINATION is defined as the process by which flowering plants, through the aid of external agents such as insects,wind, water and other animals, are able to transfer pollen grains from an anther to a receptive stigma. Insects are the most common pollinators. They visit flowers to obtain nectar and pollen as source of food. Flowers use various features, such as colour and scent, to attract and guide insects to the food source within them. In the process of reaching their source of food, insects bring about pollination.
From the study conducted by scientist in Florida, eight(8) ponds where subjected to the the study. The first four (4) ponds had species of fishes that fed on dragonflies and dragonfly larvae, hence the reason for a decrease in the population of the dragon flies in the area around it. While the remaining four (4) ponds had NO fish and the area around it is populated with dragonflies and dragonfly larvae. This is so because of the absence of fish.
It was then noted that the dragon lies fed of the insect pollinators such as the bees and butterflies. Since these dragonflies and its larvae are abundant in the field which is close to the pond with no fish, they will grossly depend on the insect pollinators as their source of food thereby decreasing the rate of pollination in the field next to the pond with no fish.
Answer:
b) DNA polymerase can synthesize DNA in the 5' to 3' direction
DNA polymerase is only able to synthesize a new strand of DNA and not mRNA. It is only able to do this in the 5' to 3' direction. The leading template strand runs in the 3' to 5' direction and so the new complementary strand is synthesized in a 5' to 3' direction in one continuous run, following the replication fork as it 'unzips' the DNA.
hope it helps btw i did this test and i got it correct
check my screenshot below
please mark me brainliest
