State 2 of Newtans three laws
(PLS HELP ASAP!!)
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.

Determine which situation could NOT be an example of interspecific competition.
A. Two organisms competing for food.
B. Two organisms competing for a mate.
C. Two organisms competing for water.
D. Two organisms competing over territory.
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.
What is an Interspecific competition?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.

The world population has surpassed 7 billion and is continuing to increase dramatically. Select the factor that has demonstrated an
inverse relationship to population growth.
es )
A)
deforestation
B)
violent political conflict
spread of communicable diseases
D)
biodiversity of plant and animal species
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.
What inverse relationship to population growth?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.

what factors do you predict might influence the likelihood of mutations occurring in viruses?
The factors which might influence the likelihood of mutations occurring in
viruses is Spontaneous nucleic acid damage and replication inhibition.
Viruses are pathogenic micro-organisms which mutate rapidly than the
humans do. Its ability to mutate very rapidly inside the host cells is what
makes it unique and deadly.
Factors which might influence mutations in Virus include nucleic acid
damage and replication inhibition. When this occurs, the virus isn't able to
mutate thereby causing less damage to the host.

How would a biomagnification “pyramid compare with an energy pyramid?
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.
What is biomagnification?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.

Ozone in the stratosphere is a toxic pollutant that can cause tightness or shortness of breath.
True
False
Ozone in the stratosphere is a toxic pollutant that can cause tightness or shortness of breath is a true statement.
What is ozone layer?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.

How did the new island in the Pacific Ocean near the Vava'u Islands form? See below
for a picture of the new islands and for the location on earth.
Answer:
They were created from the subduction of the western-moving Pacific plate under the Australia-India plate at the Tonga Trench. The Tongan Islands sit on the Australia-India plate just west of the Tonga Trench. These volcanoes are formed when materials in the descending Pacific plate heat and rise to the surface.
