Answer:

The correct answer is - Increase in competition. destroy habitat, water and resources scarcity, and reduction in population.

Explanation:

Landslides are the movement of debris, rock, or land. It can be lethal and affects the ecosystem in various ways. The major effect on the ecosystem is destroying the resources and habitat of the organisms and even pollute water streams and water bodies with excess debris and sediment. It affects water quality and aquatic organism's habitat.

Cloud [144]

Answer: The phenotypic variation was more in play during the tests because of the presence of environmental factor (monochromatic light). The genotypic variation was a result which is evident in the viable and fertile hybrids

Explanation: Phenotypes are traits of living things which are visible to us. Examples of such traits are behaviours, colour, shape, size, e.t.c. Genotypes is the genetic blueprint of a living thing. It is the genetic code that forms the physical traits in an organism (phenotype). For example, the code that tells a lady to have red hair is the genotype while the resulting red hair in the lady is the phenotype.

Phenotypic variations simply put are different physical variables in phenotypes that exists in a given population. For example, we have people with different body weights, heights, eyecolour, hair and shape of head. Genotypic variation is the difference in genotypes between different species or individuals of the same species.

There are two known causes of phenotypic variations and they are genes or environmental factor. In the given data, the monochromatic (made of one colour) light induced phenotypic variations in the male species and led to indiscriminate mating which resulted in viable and fertile hybrids (genotypic variation).

Describe how human male gametes differ from female gametes​
Evgesh-ka [11]

Explanation: Gametes are the cells used during sexual reproduction to produce a new individual organism or zygote. The male gamete, sperm, is a smaller, mobile cell that meets up with the much larger and less mobile female gamete, egg or ova. Both sperm and egg are only haploid cells. They only carry half of the chromosomes needed.

What does the ocean do to the CO2 in the atmosphere?
LenaWriter [7]

Answer:

It absorbs.

Explanation:

The ocean absorbs carbon dioxide from the atmosphere wherever air meets water. Wind causes waves and turbulence, giving more opportunity for the water to absorb the carbon dioxide. Fish and other animals in the ocean breathe oxygen and give off carbon dioxide (CO2), just like land animals.
