If a biologist is measuring diversity by calculating the proportion of individuals of each species, he or she is actually calculating the species evenness of species in the community.
What is species evenness?When there is an environmental gradient in the study region, systematic sampling is performed.To take systematic samples along the environmental gradient, a transect is utilized.A population is a collection of creatures belonging to the same species that coexist in a certain location. Within a given area, more than one population may exist. It's possible for populations of Saguaro cacti, Cactus Wrens, and Bark Scorpions to coexist in the same places.A population is a collection of people belonging to the same species who are present in the same location at the same time. All of the people in all of the interacting populations in a given area make up a community.Learn more about population here:

2. Which hormone stimulates the removal of sugar from the blood?
a. Glucose
b. Insulin
c. Glycogen
d. Glucagon
Answer:
Glucagon
Explanation:
Glucagon works along with the hormone insulin to control blood sugar levels and keep them within set levels. Glucagon is released to stop blood sugar levels dropping too low (hypoglycaemia), while insulin is released to stop blood sugar levels rising too high (hyperglycaemia).
Suppose that the same island experiences environmental
conditions that prevent the growth of large seeds. What do you think would happen to
the average size of finch beaks? Explain your reasoning.
Answer:
The size of finch's beak depends on the size of seeds.
Explanation:
The average size of finch beaks also changes because the size of finch beak changes according to the size of seed available. If the environment contains large sized seeds so the population of finch having small beak size increases due to food availability while on the other hand, if the region contains large sized seeds so the population of finch having big beak size increases so according to the size of seeds, the size of finch's beak also changes.

If you drink a gallon or more of fresh water at a single sitting, what happens to your blood and then what might happen to the cells in the blood?
Answer:
I hope this will help
Explanation:
When you drink too much water, your kidneys can't get rid of the excess water. The sodium content of your blood becomes diluted. This is called hyponatremia and it can be life-threatening.
Hyponatremia is a low sodium concentration in the blood. It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. Symptoms can be absent, mild or severe. Mild symptoms include a decreased ability to think, headaches, nausea, and poor balance.

A new species can form when a group of individuals remains completely separated from the rest of its family long enough to evolve different traits that prevent reproduction. true or false
Answer:
True
Explanation:
It is true that a new species can form when a group of individuals remains completely separated from the rest of its family long enough to evolve different traits that prevent reproduction.
This happens due to physical separation of members of a population.
Geographic isolation :Geographic isolation occurs when populations are separated by geographical barriers like rivers, mountain etc.The population is separated from exchanging genetic material within the same species and results in evolution of a different trait.

DNA carries the information needed to make proteins. How is this information used to make proteins?
Answer:
The information contained in DNA is expressed giving rise to proteins, through transcription processes, a step by which the information is transferred to a messenger RNA molecule (m-RNA) and, through the process of translation, the message carried by m-RNA is translated into protein.
Answer:
DNA is transcribed into mRNA. Ribosomes "read" the mRNA and translate each group of three nucleotides into amino acids to build proteins, with the help of tRNA.

What form of energy is responsible for producing changes that occur in Earth’s hydrosphere?
Answer:
the sun because energy from the Sun heats the Earth unevenly. As a result, convection currents develop in the atmosphere and ocean. These redistribute heat in the atmosphere and oceans.
Answer: Hydropower is created when rapidly flowing water turns turbines inside a dam, generating electricity. Nuclear energy is produced at power plants by the process of nuclear fission. The energy created during nuclear reactions is harnessed to produce electricity.

What needs to happen FIRST for a fossil to form?
Answer:
for a fossil to form, an organism must be buried quickly so that any oxygen is cut off and its decay slows down or stops. ... Fossil formation begins when an organism or part of an organism falls into soft sediment, such as mud.
Explanation:
For a fossil to be formed, it is required for a plant or an animal to be covered by the sediment. Thus, the correct option is D.
What is the process of fossil formation?Fossils are the preserved evidence of the organisms which were present on this planet once. There are four types of process which contribute to the formation of a fossil. These are mineralization, carbonization, encrustation and distillation. These processes occur once a living organism has become trapped within the surrounding sediment, and it is primarily depend upon the mineral composition of silt and water available.
Fossil formation begins when a living organism or any part of an organism falls into the soft sediment, such as mud. The organism or part of it then gets quickly buried by more sediment. As more and more sediment collects on top of the organism, the layer with the organism or part becomes compacted and it undergoes deep into the Earth.
Therefore, the correct option is D.

A population of rabbits lives in a grassy field that is lush and green in summer and covered in snow in winter. At the start of the summer,
75% of the population are white rabbits, and the remaining 25% of the population are brown rabbits. In rabbits, white (W) is dominant
over brown (w). During the summerthe field where they live experiences a drought. The
summer drought lasts for two years, through
many generations of rabbits.
Which prediction BEST estimates the expected percent of white and brown rabbits in the population at the end of the
drought?
O A. The rabbit population will consist of 0% white rabbits and 100% brown rabbits.
OB. The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
C. The rabbit population will consist of 95% white rabbits and 5% brown rabbits.
D. The rabbit population will consist of 80% white rabbits and 20% brown rabbits.
Answer:B
Explanation:
The rabbit population will consist of 35% white rabbits and 65% brown rabbits. Therefore, option B is correct.
What are the limiting factors of the rabbit population?Until a limiting factor, such as low reproduction, food scarcity, predation, disease, and/or weather conditions restrict populations, the population tends to grow.
Some density-dependent limiting factors are the spread of pathogens, competition for nesting locations, the destruction of habitat, increase in the population of predators. Several predators, including raptors and coyotes, use rabbits as food, but in urban and suburban areas, cats and dogs pose the biggest threat. Some abiotic limiting factors are drought, flood, earthquake, and all types of natural disasters.
The rabbit population will consist of 35% white rabbits and 65% brown rabbits. Therefore, option B is correct.
