Answer:

C. gametes

Explanation:

The alternation of generations is a process of reproductive cycles that occur in plants, algae and cnidarians. The main characteristic of this type of reproduction is that it happens in two different generations alternating in a single life cycle of the organisms.

For this process to occur in plants, it is necessary that there is a generation that produces spores (sporophytic generation) and a generation that produces gametes (gametophytic generation). The generation that produces spores should produce diploid cells, while the generation that produces gametes must produce haploid cells.

When haploid cells arise from the germination of spores (which are haploid), the phase called gametophytic begins in the body, where the formation of two gametes (one male and one female) occurs. These gametes will merge during fertilization, generating a diploid embryo, which will undergo several mitoses until it becomes an adult that is capable of forming spores.

I would support the factory if I lived 50 miles away from the planned factory location. However, I would be worried if I only lived one mile away from the planned factory, because of possible health effects, bad smells, and a potential decrease in property values.

<h3>What is Air pollution ?</h3>

Factories contaminate the air by blowing chemical vapors and smoke out through vents and smokestacks, and by burning waste in open dumps or incinerators.

Exhaust from generators, diesel trucks, and buses also fill the air with dangerous gases.

The amount of toxic gases that factories release into the air increases health and environmental damages. In factories, toxic materials and gases, like carbon dioxide and methane, are burned and pumped out into the atmosphere.

Evolution can be guided by random processes. What is the effect called when some genotypes are lost in a small population over t

soldi70 [24.7K]

Answer:

Genetic drift

Explanation:

Genetic drift is defined as the random change in allelic frequencies from one generation to the other.

Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to randomly fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.

Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.

maxonik [38]

Answer:

The interaction between the sloths and the leaves they eat is an example of a predator-prey relationship. In this example, sloths are herbivores that acquire their nutrients and energy from the plants they eat. The colors of coral snakes provide these animals with mimicry to avoid predation. Specifically, their coloration helps them advertise their toxicity. The interaction between the hosts and the ticks that live on them can be characterized as parasitism, because one species feeds on the other.

Explanation:

Predator-prey relationships are those in which a specie feeds on another specie. The sloth is the predator that feeds on the leaves which are its prey. Herbivores feed on plants. Therefore, the sloth are rightly classified as herbivores.

Coral snakes are brightly colored with red, yellow, and black patches that warn potential predators of their toxicity. Ticks living on hosts are parasitic because the ticks feed on their host.
