Which are required for natural selection to occur?
inheritance, isolation, adaptation
variation, overpopulation, adaptation
isolation, overpopulation, speciation
variation, inheritance, speciation
Answer: B
Explanation:
Natural selection is a mechanism of evolution which was given by Charles Darwin. According to natural selection, individuals with heritable traits which favor their reproductive success as well as survival are selected by nature.
For natural selection to take place, there should be variability as well as higher reproductive success . Eventually natural selection causes individuals to become adapted to their environment (i copied the answer from someone else but here you go so you don't have to search for them)

Explanation:
Coral reefs are actually colonies of small polyps that each live within a hollow cylinder of calcium carbonate, which it excretes. Their tentacles extend above the top of this cylinder and sweep in small organisms and other food scraps. On the outside of the hollow cylinders single-celled green algae live. These algae use the carbon dioxide and nitrogen wastes given off by the corals to produce sugars and oxygen through the process of photosynthesis. The sugar and oxygen are then used by the coral for growth. In addition, the algae are protected by the structure of the reef from animals that might eat them.
a.) Mutualism
b.) Commensalism
c.) Parasitism
d.) Predator-Prey

The global warming is the main cause of sea level rise. A warming climate can cause seawater to expand and ice over the land to melt. The Sea level rise due to the change of climate. The correct option is A.
What is sea level rise?The average increase in the water level of the earth's oceans due to the global warming caused by human activities which have increased the greenhouse gases in the atmosphere is defined as the sea level rise.
The gradual increase in the temperature of the earth which is commonly caused by the emission of greenhouse gases like carbon dioxide, chloro fluro carbon and other pollutants is known as the global warming.
The incredible increase in the temperature due to global warming resulted in an increase in the melting of glaciers which have led to an increase in the sea level.

What would most likely be produced when a cell with eight chromosomes undergoes mitosis?
Answer: two cells with eight chromosomes each
Explanation:
A diploid cell that enters mitosis with eight chromosomes will divide to produce two diploid daughter cells, each of which also has four chromosomes.
What is mitosis?
Mitosis is the process by which a cell replicates its chromosomes and then segregates them, producing two identical nuclei in preparation for cell division. Mitosis is generally followed by equal division of the cell's content into two daughter cells that have identical genomes
it is also known as equational division.
so, if a cell with 8 chromosome undergoes mitosis , it will produce two daughter cell with four chromosome.

Answer:
4
Explanation:
An atom with atomic number of 4 will have a proton number of 4.
Atomic number is the number of protons in an atom. Therefore, when given the atomic number, it shows the number of protons in the atom.
The number of protons is the number of positively charged particles in the nucleus of an atom. The atomic number is used to arrange elements in their right position on the periodic table.SThose that disputed the flat Earth theory countered the claim by observing that Christopher Columbus was able to sail around the Earth without falling off thcientific laws describe natural relationships that have been tested repeated

what will happen to the concentrations of atp, nadph, and sugar when you add diuron.
Answer: its decreas for all of them
Explanation:
Cuz I did it lol
The application of diuron decreases the activity of ATP, NADPH, and sugar production.
What is diuron?Diuron is a powerful herbicide and algaecide that blocks the natural process of photosynthesis and inhibits the weed's ability to convert light energy into chemical energy.
It stops the process of photosynthesis by stopping the creation of oxygen and blocking the transfer of electrons from photosystem II in plants, which stops the electron transport chain from working properly.
In the long run, this causes a reduction in the amount of ATP, NADPH, and sugar that plants produce.

allosteric inhibitors change the shape of the enzyme
True or False
Answer:
T
Explanation:
Their binding induces a conformational change that reduces the affinity of the enzyme's active site for its substrate. The binding of this allosteric inhibitor changes the conformation of the enzyme and its active site, so the substrate is not able to bind.

PLEASE HELP!!! What does the graph indicate about the relative acidity of the stomach and small intestine??
Answer:
That the stomach is more acidic than the small intestine.
Explanation:
If i understand the graph correctly, the graph indicates that the stomach is relatively more acidic than the small intestine. This Is because the data for the stomach (the blue line) is at the left side of the x-axis, from 1 to 5, while the data for the small intestine (the orange line) is more to the right, meaning that the small intestine has a higher pH. The higher the pH, the lower the acidity. So since the stomach has a lower pH, it has a higher acidity.
The stomach is more acidic than the small intestine.
The graph hows the pH of the small intestine and the stomach respectively. We know that the pH is a measure of the acidity or alkalinity of a substance. A pH value of 0 - 6.9 indicates acidity. 7 indicates a neutral substance while 8 - 14 indicates a basic substance.
We can see from the graph that the stomach is more acidic than the small intestine because it has a lower pH which indicates high acidity.

a pyramid of energy for this ecosystem would look more like the pyramid of numbers or biomass
Answer:
biomass; numbers
Explanation:
For Savvas Realize
The pyramid of energy for biomass would look more like the pyramid of numbers.
What is pyramid of energy?Primary producers occupy the highest biomass in a pyramid of energy. In general, only 10-20% of biomass is transferred from one trophic level to the next.
In general, biomass pyramids are upright because biomass decreases as trophic level increases.
Ecological pyramids are a method of visualizing a food chain, using either the mass of organisms or the total population of organisms at each stage of the food chain.
Pyramids of biomass are always of the "classic" shape, whereas pyramids of numbers can be inverse or have levels of varying width.
Thus, the pyramid of numbers has similarity with that of biomass, but pyramid of biomass is more accurate than that of the number.
