Answer:A
Explanation:
A variety of organisms contributes most to promoting sustainability in an ecosystem. Hence, option C is correct.
What is an ecosystem?An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors. Abiotic variables, or nonliving components, coexist with biotic components in ecosystems.
Based on their overall environments, ecosystems can be divided into three basic categories: freshwater, marine, and terrestrial. Individual ecosystem types based on the environmental habitat and creatures present can be found within these three categories.
A variety of organisms contributes most to promoting sustainability in an ecosystem. Hence, option C is correct.

What is the relationship between genetic mutations and DNA?
Answer:
Change in DNA sequence leads to genetic mutation.
Explanation:
A mutation is a change in DNA. The organisms DNA can affect the way it looks in the future and can cause changes in the aspects of that organisms life. Mutation is quite crucial to evolution and is the raw material of genetic variation. The way the DNA functions can affect the mutation.
Research the differences that exist between mitosis and binary fission. Identify at least one difference, and explain why it is significant.
The difference between mitosis and binary fission is that while mitosis occurs in eukaryotes and binary fission occurs in prokaryotes.
Mitosis and binary fission are forms of cell division that duplicate cells. Binary fission occurs in prokaryotes which are the cells that do not contain a nucleus.
On the other hand, mitosis occurs among the eukaryotes which are the cells that have a nucleus. Also, binary fission doesn't include spindle formation in its process which makes it faster than mitosis.

Different types of selection may occur within a species in response to environmental change. Which of the following would provide evidence that stabilizing selection is occurring in response to environmental conditions?
A shift in a population's frequency curve from an intermediate phenotype to an extreme phenotype
A shift toward equal distribution of all phenotype frequencies, including intermediate and extreme phenotypes
An increase in the frequency of extreme phenotypes and a decrease in the frequency of intermediate phenotypes
An increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes
An increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes favors stabilizing selection. Therefore, the correct statement is option D.
What is stabilizing selection?Stabilizing selection is a natural selection favoring intermediate phenotypes over extreme phenotypes. When the environment is stable, individuals with intermediate traits will be more fit than those with extreme traits.
Individuals with intermediate phenotypes have high chances of survival due to stabilizing selection, resulting in an increase in the frequency of intermediate phenotypes and frequency of extreme phenotypes decreases.
Stabilizing selection results in reduction of the genetic variation within a population, as extreme phenotypes are less likely to survive. The reduction in genetic variation results in more homogeneous population.
Therefore, an increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes is a type of stabilizing selection.

natural selection gizmo answer sheet?
Answer:
Natural selection is the theory that states that if individuals of different genotypes are differently qualified to live and have viable offspring under prevailing conditions, those genes that promote greater fitness must spread at the expense of others. Natural selection is therefore the process that occurs when more capable traits are inherited from one generation to another due to the interaction between the characteristics of the organism and its environment. The first to propose this theory was Charles Darwin.

A marble dropped from the Foshay Tower in Minneapolis hits the ground at 52 m/s. How high is the Foshay tower?
Answer:
Height of the Foshay tower is 138 m
Explanation:
Using the third equation of uniformly-accelerated motion under gravity:
v² = u² + 2gh
Where v is final velocity,
u is initial velocity,
g is acceleration due to gravity,
and h is height
v = 52 m/s;
u = 0 (since the marble was dropped from rest at a height above the ground);
g = 9.8 m/s²,
h = ?
(52 m/s)² = 0 + 2 × 9.8 m/s² × h
2704 m²/s² = 19.6 m/s² × h
h = 2704 m²/s² / 19.6 m/s²
h = 138 m
Therefore, height of the Foshay tower is 138 m

DNA is created by the DNA polymerase and unzipped by the DNA helicase.
What is DNA?DNA stands for deoxyribonucleic acid.
DNA is defined as a collection of molecules that are in charge of transporting and passing genetic information from parents to children.
It can also be defined as a sophisticated molecule that carries all the data required to create and maintain a creature.
There are basically two types of DNA.
Autosomal DNAMitochondrial DNAToday, DNA serves three unique purposes: genetic, immunological, and structural, all of which depend in different ways on the sugar phosphate backbone and the bases.
Replication, information encoding, mutation/recombination, and gene expression are the four functions that DNA performs.
Thus, DNA is created by the DNA polymerase and unzipped by the DNA helicase.
