A(n)\ is an area of the planet that shaves similar conditions of climate, fauna (animal life), flora (plant life) and geography

zheka24 [161]

Answer: A BIOME is an area of the planet that shaves similar conditions of climate, fauna (animal life), flora (plant life) and geography . The correct option is 1.

Explanation:

BIOME is defined as large natural terrestrial ecosystems which shares similar conditions of climate and consists of plants and animals that equally have common characteristics with their environment. The word terrestrial is used because plants form the bulk of the community in an ecosystem. The type of vegetation in a biome is largely determined by climatic factors, especially rainfall and temperature. Regions throughout the world which have similar climates have similar biomes. This causes zones of different biomes to occur from the equator to the Arctic and to the Antarctic. For example,

--> in equatorial and tropical areas where temperature is high all the year round tropical forests occur;

--> in temperate regions coniferous and deciduous forests occur;

--> while treeless plains (tundra) are found in the cold arctic regions.

Climates also changes with height above the sea level.

Explain how population sizes in nature are regulated

goblinko [34]

Answer:

Understanding Populations

Section 1 How Populations Change in Size

Objectives

Describe the three main properties of a population.

Describe exponential population growth.

Describe how the reproductive behavior of individuals can affect the growth rate of their population.

Explain how population sizes in nature are regulated.

What Is a Population?

A population is a group of organisms of the same species that live in a specific geographical area and interbreed. A population is a reproductive group because organisms usually breed with members of their own population.

Properties of Populations

Density is the number of individuals of the same species that live in a given unit of area. Dispersion is the pattern of distribution of organisms in a population. A population’s dispersion may be even, clumped, or random. Size, density, dispersion, and other properties can be used to describe populations and to predict changes within them.

How Does a Population Grow?

A population gains individuals with each new offspring or birth and loses them with each death. The resulting population change over time can be represented by the equation below.

Growth rate is an expression of the increase in the size of an organism or population over a given period of time. It is the birth rate minus the death rate. Overtime, the growth rates of populations change because birth rates and death rates increase or decrease. For this reason, growth rates can be positive, negative, or zero.

For the growth rate to be zero, the average number of births must equal the average number of deaths. If the adults in a population are not replaced by new births, the growth rate will be negative and the population will shrink.Explanation:

After three days of taking a selective serotonin reuptake inhibitor (SSRI), Derrek is disappointed because he is not feeling any

Evgesh-ka [11]

Answer:

Weeks.

Explanation:

Selective serotonin reuptake inhibitors are common antidepressants prescribed for patients with depression and anxiety disorders. However, these medications do not have an immediate effect. They usually have full effect within weeks, depending on the patient.

This delay, can be explained by the mechanism of action of these drugs. Selective serotonin reuptake inhibitors act by blocking the serotonin transporter which transports serotonin into the brain cells.This results in more being available outside the cells where it has it effects.

SSRIs don't work instantaneously because they do not target the transporter directly. They rather, bind to the DNAs that produce the transporter and therefore makes them less active and this leads to lower amount of transporters available. This process takes time.
