Explanation:
Answer: the correct option is A (increased by exposure to light).
Explanation:According to the results of this experiment, germination of tobacco seeds during the first week is increased by exposure to light. Germination is a process by which plants grow or sprouts from seedlings after a period of dormancy. One of the environmental factors that are necessary for germination of seedlings is light.
Answer:
Stratum basale layer of epidermis produces melanin pigment.
Explanation:
The epidermis is composed of mainly four layers. In some areas like palm and foot, they contain five layers - stratum granulosum. All the layers are avascular i.e. lack of blood vessels.
The stratum basale cell is the deep layer of the epidermis. It is a single layer made of basal cells. The basal layer produces the keratinocytes. The keratinocytes divide mitotically and migrate to the upper layers. The keratinocytes provide hardness to the nail and skin, also make the skin waterproof.
Another two types of cells are present in the stratum basale - Merkel cell and melanocyte cell. Merkel cells provide sensory stimulation to the skin. Melanocyte cell produces pigment melanin.
Melanocyte gives color to skin, hair. It spreads from stratum basale to the upper layer of the skin called stratum corneum. Melanin pigment protects the skin from the ultraviolet radiation of the sun.
Answer:
The answer is no, high biological fitness in one environment doesn't have to be high in another environment. Biological fitness is a term used in evolutionary biology and it is the quantitative representation of how a genotype (or phenotype) is successful (reproductively) in a certain environment. The biological fitness of an organism is dependent on its ability to survive and reproduce in a given environment. If different traits or alleles increase the fitness of an organism, those alleles will consequently increase in the gene pool, and that trait will increase in the population.
