Blood transfusion procedures, it is important to know the blood type of the receiver and the giver, since in cases of incompatibility can be blood clumping of the blood, which can lead to death.
hope this helps!
Answer:
D. Small population size
Explanation:
Hardy-Weinberg equilibrium requires the presence of a large randomly mating population. Small population size makes the population more likely to deviate from the Hardy-Weinberg equilibrium due to sampling error or chance events occurring during the genetic drift. Large population size ensures that the population maintains the constant allele frequencies over generations, that is the Hardy-Weinberg equilibrium.
Allele frequency:
Number of times an allele occurs in a gene pool compared with the number of alleles in that pool for the same gene
Examples of biting and chewing pests are snails, slugs, caterpillar, Helicoverpa, diamond black moth, beetles , termites, leaf worms, grass hoppers etc.
Examples of piercing insects are lace bugs, aphids, white flies, glassy winged sharp shooter, false chinch bugs, Bargrada bug, mealy bug, Eugenia psyllid, Pittosporum psyllid, Tipu psyllid etc.
<u>Explanation:</u>
Pests that affect crops have different feeding habits. Some pests belong to the type biting and chewing pests. These pests bite into the plant parts and chew them. This will leave circular holes in the leaves and semicircular holes in the leaf edges.
Piercing and sucking insects pierce into the plant parts and suck the sap. Removal of sap turns the plants yellow, and wilted. The growth might get stunted and in severe cases the plant may die off.
1. The lipid would be more saturated. FALSE
2. The lipids on the fatty acid tails would be much shorter. TRUE
3. The membranes would contain more cholesterol. TRUE
<u>Explanation:</u>
The mammal caribou lives I the extremely cold environment of the Arctic and thus has several physiological adaptations to survive the cold. They have short ears to reduce heat loss and have two layers of fur. The lipids in caribou legs have several adaptations
When compared with saturated fatty acids unsaturated fatty acids are more fluid at low temperatures. Thus the lipids in the legs of caribou are unsaturated to maintain fluid nature at low temperatures of the Arctic. Shorter lipids on fatty acid tails remain more fluid at low temperatures when compared with the longer ones.
Thus the lipid in the fatty acid tails will be shorter. Similarly the presence of more cholesterol in the membranes would make it more fluid in the cold conditions of the external environment. Thus the membranes would have more cholesterol.
