Answer:
Most populations do not experience: a) exponential growth
Explanation:
Populations that experience exponential growth models show an increase in proportion to their size. The increase in the population size depends on the individual´s reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.
This model states that populations live in an environment with unlimited resource availability, so the density factor does not influence population growth. There is no density-dependence effect nor competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita, and it is proportional to the population size.
Exponential growth is hardly seen in nature due to its characteristics.
Almost every environment shows a carrying capacity point. Carrying capacity is the capability of the environment to support a population. Commonly environments have limited resources and space, and as the population grows, competition increases too. The per capita growth rate decreases as population size increases. Finally, the population reaches the maximum point of carrying capacity, delimited by available resources, such as food or space.
The carrying capacity might be affected by limiting factors, which might be a result of the population density (for example, competition) or might be density-independent. This last case refers to dense-independent factors, and among these, we can mention human impact or natural disasters (fires, volcanic eruption, flooding).
Only a few species can experience exponential growth, such as bacterias.
Heredity is the passage of what from parent to offspring?
a. Genetic material
b. Oxygenated blood
c. Digestive enzymes
d. Connective tissue
Answer:
A
Explanation:
Genetic material is what passes down traits and makes us look similar to our parents
When we talk about heredity, we're talking about the precise ways that genes are used to transmit traits or characteristics from one generation to the next, hence option A is correct.
What is Heredity?The instructions for creating certain proteins, which are in charge of an individual's distinctive qualities, are encoded by genes.
The youthful creation of living creatures, known in biology as progeny, can be created by a single organism or, in the event of sexual reproduction, by two organisms.
DNA (deoxyribonucleic acid), which makes up genes, contains instructions for how cells should function as well as the traits that distinguish each individual.
Therefore, each of your biological parents contributes half of your DNA to you, and you could inherit a gene mutation from one or both of them, hence option A is correct.

Michael planted a tomato plant that produces very juicy tomatoes. When the
tomatoes began to ripen, Michael picked a tomato to eat in a salad. Michael ate the
salad with the tomato at lunch. Later that afternoon, he ran 2 miles during PE and was
sweating at the finish line. How many total energy transformations does this scenario
demonstrate?
1 (potential to kinetic)
2 (chemical to potential,
potential to thermal)
3 (solar to chemical, chemical
to kinetic, kinetic to thermal)
4(chemical to potential
potential to kinetic, kinetic to
nuclear, nuclear to thermal)
Answer:
3 (solar to chemical, chemical to kinetic, kinetic to thermal)
Explanation:
Michael ate a salad. The salad which he consumes becomes chemical energy, but the tomato he put in his salad has used solar energy, which is simply energy from the sun. The kinetic energy is when he runs 2 miles as kinetic energy is the energy gained from movement. When he stops running, he sweats, which means he is losing heat from his body, therefore the kinetic energy store transfers to the thermal (internal) energy store.

Which idea associated with relative dating helped inspire Charles Darwin's work on evolution?
Answer: The idea that the earth is extremely ancient.
Explanation:
Charles Darwin was a British naturalist who worked on the organic evolution of living organisms and in his books outlined how present-day organisms evolved from earlier, different species.
Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist including Charles Darwin, have from many fields gathered a great deal of indirect evidence that supports the theory of evolution. This evidence comes from many sources which include the FOSSIL RECORDS.
The history of life on earth is recorded in fossils (remains of organisms preserved mainly in earth's sedimentary rocks). Scientist can determine the age of rocks in which fossils occurs by using RELATIVE DATING. This method give a geological time scale, showing earth's age ( as measured by dating it's rocks), and tracing the history of life on it.
Therefore the idea that the earth is extremely ancient is associated with relative dating which has helped inspire Charles Darwin's work as an evidence on evolution.

Does DNA undergoes translation to produce proteins . RNA undergoes mutation to produce cell walls
Answer:
No
2. Yes
Explanation:
This is because DNA undergo transcription to produce RNA and RNA undergo translation to produce protein. Translation is the process where mRNA molecule is used as a template to produce protein.
RNA undergo mutation more than DNA and this is because the enzymes found in RNA viruses and participate in copying viral genomes is why it occur so. These enzymes does not have the abilities to recognize DNA damage that enzymes in most organisms have.

Which of the following data would support the claim that the gravitational force
between objects depends on mass?
O An object's weight can change depending where it is on Earth.
O A rocket can escape Earth's gravity by traveling at high speed.
O The further a planet is away from the sun, the smaller the gravitational force.
O Gravitational force is stronger on more massive planets.
Answer:
D.
Explanation:
gravitational force of attraction is stronger on more massive planets such as Jupiter
Gravitational force is stronger on more massive planets, the claim that the gravitational force between objects depends on mass, hence option D is correct.
What is gravitational force?The force that pulls things toward the center of a planet or other body is called gravity. All the planets are kept in orbit around the solar by gravity.
Earth is subject to the same gravity pull that you are. But your force doesn't really affect our globe because Earth is so much larger than you are.
In our world, gravity the moon is maintained in its circle around Earth by gravity, as are the planets in their orbits around the sun. The gravitational force is equivalent to your weight when you are at rest on or near the Earth's surface.
Therefore, gravitational force is stronger on more massive planets, hence option D is correct.

Answer:
If an organism has a beneficial trait, they have a higher chance of survival, and if they can survive they can reproduce too.
Example: Speckled moths camouflage with the bark of trees and are not easily seen by predators. Black moths do not camouflage with the bark of trees and are easily seen by predators, therefore the black moths are eaten. Because the black moths have been eaten they cannot reproduce and pass on the trait for black wings to their offspring, but the speckled moths are able to reproduce because they survived and are able to pass on the speckled wing trait to their offspring.

If all of the moths had been completely identical, could they have evolved?
Answer: i would say no
Explanation:
Answer:
Depends on the Genes
Explanation:
If all of the moths carry one dominant gene and one recessive gene then it is possible this is due to the fact that if each parent has a recessive gene it can appear a 1/4 chance in their offspring causing a change or evolution of the moths. This idea that recessive genes can sometimes be the key of survival in a species such as snow foxes being white even though white hiar is a recessive trait.
