The correct answer is immunoglobulins.
Immunoglobulins, also called as antibodies, refer to the molecules or glycoproteins generated by the white blood cells (plasma cells). They function as an essential component of the immune reaction by uniquely determining and combining with the specific antigens, like viruses or bacteria, and helps in destructing them.
Answer:
The changes in the frequencies of blue and green eye alleles can not be predicted since genetic drift is a random event.
Explanation:
Genetic drift is the change in the allele frequencies of a population caused by some chance event. The effect of genetic drift is more pronounced in smaller populations since random events cause changes of greater magnitude in a small population. It can cause the complete loss of an allele from a small population.
According to the given information, the frequencies of alleles for green and blue eyes are changed by genetic drift which in turn would produce random evolutionary changes Either of the alleles may be eliminated from the population irrespective of the fact that the allele is beneficial or harmful. Thus, genetic drift would change the frequencies of the allele in an unpredictable manner.
A) 12 is the answer because sex cells have half as many chromosomes as the offspring will have, half from the mother, the other half from the father.
During an experiment the factors we observe are
1) what reactions are taking place(if any)
2) is there a change in the colour of the substances used
and so on. Observation totally depends on the experiment
the things we measure are weight, mass, time, temperature,etc.
hope it helps u
Answer:
No
Explanation:
Not all greenhouses have pest insects because there can be butterflies in a greenhouse to pollinate the plants and bees help pollinate too. There are some pest insects though such as the greenhouse white fly, Encarsia Formosa, and the mealybug
