For example, consider an effort to decontaminate a small village’s water supply. This effort is projected to increase the carrying capacity from an initial population of 400 people (P = 400) to 450 people (K = 450) during the course of 10 years (x = 10).

Burning biomass—a natural resource—for fuel doesn’t emit additional CO2 into the atmosphere. However, biofuel production reduces the area’s biodiversity because corn, which is a primary source of biomass, is overplanted. Grasslands and fields once inhabited by a large variety of flowers, grasses, insects, and pollinators are being cleared as the demand for corn increases. The impact of eliminating these species and decreasing the area’s biodiversity then spreads as other plants and crops that relied on the insects and pollinators are threatened. These negative consequences can then magnify throughout the ecosystem.”If an ecosystem is no longer able to sustain its biodiversity, what potential impact could that fact have on the carrying capacity and growth rate of the human population over time?

What would the climate be like without the greenhouse effect? Back to normal with no threat of global warming
Too cold for many living organisms
Mostly temperate near the equator and extremely cold at the poles
Extremely dry with no moisture in the air

Answers

The correct answer is option B

The temperature could have been too cold for some of the organisms without greenhouse effect.

The average temperature of the earth could have been much lower than what is today.

It is the green house effect that the temperature is optimum for the survival of all the organism otherwise only that organism could have survived who can live at lower temperatures.

it would be to cold cuz

Which organisms utilize a one-way air flow through their lungs to maximize airflow efficiency and oxygen consumption?

Answers

The answer is birds.

Birds utilize a one-way airflow through their lungs to maximize airflow efficiency and oxygen consumption. Although they inhale and exhale through one trachea, air flows in one direction through birds lungs. This is enabled thanks to air sacks. When birds inhale, air travels through the trachea, which further divides into two bronchi. The part of the air enters the lungs, and the other part remains in posterior air sacks. After the first exhalation, the fresh air from the posterior air sacks enters the lung and displace the spent air which is moved to the trachea. In case there is fresh air in the trachea, spent air is moved to anterior air sacks and after following exhale, it flows out from the trachea.

When traits from the parents blend together to form a new trait in the offspring, it is called _________Codominance
Incomplete dominance
Complete dominance
Recessive

Answers

When traits from the parents blend together to form a new trait in the offspring, it is called codominance.

What is codominance?

When two alleles or genotypes (of both homozygotes) are expressed jointly in offspring, it is referred to as codominance (phenotype).

Two other types of genetic inheritance are codominance and incompletedominance. It basically means that no allele can prevent or stifle the production of the other allele through codominance.

Therefore, in terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person.
