Answer:

Prophase I

Explanation:

In prophase I, each pair of homologous chromosomes (one chromosome from each parent) lines up side by side. This aligning of homologous chromosomes is called synapsis. At synapsis, the homologous chromosomes are held tightly together

along their lengths. While they are lined up, segments of the chromosomes may be exchanged. This process of exchange of genetic information is an important mechanism for providing genetic diversity, and is discussed later in this section. As prophase I continues, the centrosomes move to the poles of the cell and the spindle apparatus forms.

Food chains show energy transfer between organisms. The size of a food chain can vary, yet there is a limit to the number of lev
vovikov84 [41]

The correct answer is option Energy is lost at each trophic level.

In a Ecological pyramid, the energy is transferred from the producer to the consumer level. The ecological pyramid is triangular in  structure, this is because the number of organism on each successive trophic level is less than the preceding one or the one below it.

The reason of this shape of ecological pyramid is on subsequent trophic level, the amount of energy transferred is only 10%. The rest of the energy is dissipated in the environment in the form of heat. As only 10% of total energy is transferred to the subsequent level, The amount of energy reaching to tertiary consumer is very less that it cannot meet the energy demand of next level.

1. What is cultural control? What are the practices done in this approach? What are the advantages and disadvantages of cultural
timama [110]

1.a.In agriculture cultural control is the practice of modifying the growing environment to reduce the prevalence of unwanted pests. Examples include changing soil pH or fertility levels, irrigation practices, amount of sunlight, temperature, or the use of beneficial animals or insects.

1.b. Cultural control is using the production or utilization methods of a commodity with a concern for insect management. Cultural control practices are usually multipurpose technical procedures that create environments that either avoid high-risk situations for infestations or develop unfavorable conditions for pests.

1.c.Simplicity and low cost are the primary advantages of cultural control tactics, and disadvantages are few as long as these tactics are compatible with a farmer's other management objectives (high yields, mechanization, etc.).

Why would you probably not see a volcano on the east coast of the United States?
DerKrebs [107]

D. There are no major fault lines or hot spots close by.

Why?

Because "They don’t occur anywhere else other than along the Ring of Fire" is incorrect, the Ring of Fire is just a place where many volcanoes are.

Because "The composition of the rock in that area is not conductive to eruptions." they type of rock doesn't play that much of a role in the formation of volcanoes

Because "The magma doesn’t have enough silica or gas to form an explosive eruption." It isn't a gass that is found, it is the build up of pressure from fultlines moving and things on the inside of the earth.
