Ozone in the stratosphere is a toxic pollutant that can cause tightness or shortness of breath is a true statement.

One layer of the stratosphere, the second layer of the Earth's atmosphere, is the ozone layer. The layer of insulating gases that clings to our planet is known as the stratosphere.

A small layer of the Earth's atmosphere called the ozone layer absorbs nearly all of the sun's harmful UV energy. Areas of the ozone layer degradation are frequently referred to as "ozone holes." That is incorrect. Damage to the ozone layer is more akin to a very thin patch than a hole.

Therefore, Ozone in the stratosphere is a toxic pollutant that can cause tightness or shortness of breath is a true statement.

Answer: it would be D

Explanation:

The situation that could not be an example of interspecific competition is two organisms competing for a mate. Thus, the correct option is B.

Interspecific competition may be defined as an instance of competition between individuals of different species.

The situation of two organisms competing for a mate illustrates an example of intraspecific competition. This is because the two individuals mate with a member of their own species in order to produce fertile offspring.

The individuals of different species do not undergo interspecific competition.

Therefore, the correct option for this question is B.

Answer:

smog

Explanation:

Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities.

Answer:

Sensory receptors respond to stimuli.

Explanation:

They can be classified by their location, the type of stimulus they detect or by their structural complexity.

Sensory receptors  are the receptors which respond to stimuli within the

body. The body have five major sensory organs which include the eyes,

nose, tongue, ear and skin.

These organs have receptors which is responsible in the transmission of

signal to the brain for action. The brain acts depending on the signal

received which is usually in the body's best interest.

This makes our sensory organs important and very delicate and as a result

Answer:

Energy pyramid depicts flow of energy in the ecosystem: source of all energy in ecosystem is the SUN. Producers are only organisms in ecosystem who can trap the solar enrgy. So base of energy pyramid is always wide. A biomass pyramid shows the total dry mass of all living organisms at each trophic level.

Explanation:

Because the amount of the pollutant increases as it goes up the food chain, the biomagnification pyramid is inverted whereas the energy pyramid is consistently upright.

Biomagnification is the amassing of a chemical by an organism as a result of exposure to both food and water, resulting in a concentration that is higher than what would have been expected from equilibrium and higher than what would have occurred with only water exposure.

When dangerous chemicals like DDT that remain in the environment are indirectly absorbed by living things through food, this process is known as biomagnification.

When a higher-order organism consumes a lower-order organism that contains such compounds, the chemicals may accumulate in the higher-order organism.

The biomagnification pyramid is upside down because the amount of the pollutant increases as it moves up the food chain. The energy pyramid, however, is always upright.

Thus, this can be the comparison between the energy pyramid and biomagnification.

Answer:

D

Explanation:

As population grows all the above factors increase expect the biodiversity of animal and plant species.

On a basic level, it is obvious that population increase and per capita income growth are related. Per capita income is simply total income divided by the population.  Thus, option D is correct.

When attempting to forecast changes in population size, demographers frequently focus on four essential criteria.

The population's starting age profile (whether it is relatively young or old to begin with), migration, and fertility rates (death rates; life expectancy).

Depending on particular environmental factors, two different patterns of population expansion may manifest: In a perfect, limitless environment, an exponential growth pattern (J curve) manifests itself.

The development of a logistic growth pattern (S curve) occurs when external forces reduce the pace of growth.

Therefore, The gap between the growth rates of income and population is roughly equivalent to the growth rate of per capita income.

Answer:

The answer is C diploid Phase

Answer:

The answer is C.

Explanation:

Plants that we reconize today spend the majority of their life in the diploid phase.

During the sporophyte phase, a diploid plant body (one with two sets of chromosomes) develops and finally generates spores via the process of meiosis. Mitotic division of these spores results in the formation of gametophytes, which are gamete-producing organisms that are haploid (have a single pair of chromosomes).

The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.

Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.

During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.

When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.

1. Something at rest or in motion in all constants will remain that way unless acted upon by a force.

2. F=ma

Explanation:

Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Force equals mass times acceleration; it states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
