Some microorganisms can thrive at and/below freezing point (0 degrees for water). They live in high mountains or the sea.
Pathogens in food such as campylobacter jejuni, listeria monocytogenes, yersinia enterocolitica, aeromonas hydrophilia and penicillum are examples of microorganisms that survive below 0 degrees Celcius.
Carbon dioxide, Water (sweat), and Energy in the form of ATP.
Populations of organisms that exhibit a high degree of variation have a greater chance for survival than populations of organisms that show little variation is described below.
Explanation:
- Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.
- The genetic variation in the population is increasing due to selective pressure. The genetic variation in the population is decreasing due to selective pressure. The genetic variation in the population is increasing due to gene flow. The genetic variation in the population is decreasing due to gene flow.
- Genetic drift is a random change in allele frequencies. These random changes in allele frequency can accumulate over time. ... Small samples can vary more markedly from the larger sets from which they are selected than larger samples, so genetic drift is more powerful in smaller populations
- Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
Answer:
D. Mutually beneficial: the bee receives pollen and the flower gets help with its reproduction
Explanation:
It is a mutually beneficial relationship because the flower provides the bee with nectar and pollen. Also, the bee provides the flower with a means to reproduce by spreading pollen from flower to flower through pollination.
The central lumens of thyroid follicles are filled with colloid, which consists of the protein thyroglobulin, a molecule that binds and stores thyroid hormone.
Thyroglobulin is a protein produced primarily by the thryroid gland. The thyroid gland is mainly made up of tiny, round shaped structures called follicles that produce and store thyroglobulin. Thyroglobulin acts as a substrate for the synthesis of the hormones (thyroxine and triiodothyronine) and also the storage of the inactive forms of thyroid hormone and iodine. Thyroxine and triiodothyronine assist in the regulation of the utilization of energy by the body.
