What would happen to the
population of grass population if
the cheetah disappeared? Why?
Answer:
the cheetah is a predator and hunter at the top of the food chain, so its disappearance would impact its prey and so on down the line. It is usually the case that the disappearance of animals and organisms that are more widespread in the ecosystem and food chain have the greatest impact and there would be very little grass left because there are so many prey left since the cheetah is not there to decrease the population

Pedigrees and karyotypes provide the means for individuals to identify their risks of genetic disorders. What can be observed on a karyotype but not on a pedigree?
family carriers of a genetic disorder
family history of a genetic disorder
risk of a genetic disorder in offspring
a visual image of a chromosomal defect
Answer:
D) a visual image of a chromosomal defect
Explanation:
The genetic disorders, or inheritance of traits, and abnormality in the chromosome can be studied through pedigree charts and karyotyping.
The correct answer is Option D, a visual image of a chromosomal defect.
The difference between karyotype and pedigree chart can be explained as:
Pedigree charts are the diagrammatic representation of the phenotypes of a particular gene or the lineage of the ancestors. The chart is used to study the inheritance of a trait or a disease. Karyotype refers to the collection of chromosomes, in which disorders or structures of chromosomes are studied. Karyotype provides visual damage or abnormality in the structure of chromosomes.
Thus, the correct answer is Option D.

Explanation:
Tornados form over land
Hurricanes form over water
Tornados = spiraling wind
Hurricanes = spiraling water mixed with wind
Answer/Explanation:
D) Hurricanes are caused near tropical oceans. The wind, pressure, and temperatures of tropical areas make it a common place for it to occur.
Type of relationship between Iguanas and Basilisk
Answer:
Lizards are reptiles. Like snakes, iguanas have scales, lay eggs, and are cold-blooded. So iguanas shed their skin, lay their eggs in large nests, and bask in the sun to boost their body temperature. Iguanas require year-round warm weather to survive in the wild.
Basilisk lizards have special toes on their rear feet. These long toes have fringes of skin like scales that spread out in the water to increase the surface area of the foot making contact with the water. When they run on water, they pump their legs rapidly, slapping their feet hard against the water.
All iguana families with the exception of basilisks share sex chromosomes

When the viral DNA becomes active in the lysogenic cycle, which life cycle does it enter?
A.lytic
B.lysogenic
C.cell cycle
D.DNA replication
Answer:
A.lytic
Explanation:
Lysogenic and lytic cycles are two cycles of viral reproduction. In the lysogenic cycle, the viral DNA is incorporated into the host cell genome. Then, it can be passed on to the cell's daughter cells after it divides.
The other cycle of viral reproduction is called the lytic cycle. In the lytic cycle, the DNA is activated (transcribed). Viral particles can then assemble and replicate, and lyzing the host cell.
Which phase change involves the release of heat?
Answer:
Condensation
Explanation:
There are two phase changes where the heat energy is released: Condensation: When gas condenses to liquid the quantity of energy converted from chemical to heat is called the Heat of Vaporization.
The reaction which involves the release of heat is known as exothermic reaction. The examples of exothermic reactions include condensation and freezing process in which a phase change is observed from gas to liquid and liquid to solid, respectively.
What is Phase change?
The three phases in which a matter can be obtained are solid, liquid, and gas. The matter can change its phase by absorbing or releasing energy.
The process in which a substance undergoes reaction by gaining the energy is called endothermic reaction whereas the process in which a substance lose energy in the form of heat to undergo phase transformation is called exothermic reaction.
If heat is produced from a substance, in the processes like freezing and condensation, then the process is exothermic. In this process, the heat is decreasing with the speed of the molecules which causes them to move slower results into conversion of liquid to solid and gas to liquid. These phase changes release heat to the surrounding.

As glucose and other biomolecules are broken down by aerobic respiration, the cell’s chemical reactions capture as much energy as possible into a few molecules of ATP and many molecules of 2 electron energy carrier molecules called what?
Answer:
NAD - nicotinamide adenine dinucleotide
FAD - flavin adenine dinucleotide
Basically, NAD and FAD carry electrons to the electron transport chain in the inner mitochondrial membrane. These electrons are deposited near the beginning of the electron chain, and then these electrons are passed on from one protein to the next.
As these electrons move through the electron chain, they release energy, and some of this energy is captured in the form of an electrochemical gradient and used to make ATP.
Energy contained in the bonds of glucose is released in small bursts, and some of it can be captured in the form of ATP, a small molecule that is used to power reactions in the cell.
ATP = adenosine triphosphate
Answer:
I think it might be nicotinamide adenine dinucleotide (NAD+) and flavin adenine dinucleotide (FAD).
Which Best Describes why Plant cells have chloroplasts and animal cells do not
A- Plant cells need chloroplasts to make DNA because most plant cells do not contain a Nucleus
B- Plant Cells need chloroplasts to make food because most plants cannot move to get there food on their own
C- I dont know
D- Plants cells need Chloroplasts to move materials in and out of the cell because most plants cells do not Contain a Cell Membrane
Answer:
B
Explanation:
Plant cells need chloroplast to make food because most plants cannot move to get their food on their own
Answer: D
Explanation: Because The Chloroplast is the Gate to move waste out of the cell and nutrients into the cell. Most plants do not contain a cell membrane.
