Answer:
The Carbonic-Acid-Bicarbonate Buffer. In animals with lungs, the carbon / bicarbonate buffer system is especially effective. In these animals, the H2CO3 in the blood plasma is in equilibrium with the gaseous CO2 present in the airspace of the lungs, which represents a practically unlimited reserve of CO2 that can participate in the equilibrium.
Explanation:
In the Carbonic-Acid-Bicarbonate buffer system, 3 reversible equilibria take place between the CO2 gas in the lungs and the bicarbonate dissolved in the blood. The bicarbonate ion (HCO3-) can combine with a proton (H +) to form carbonic acid (H2CO3), thus absorbing protons from solution and raising blood pH. Carbonic acid, which can be formed from CO2 and water, can dissociate into H + and HCO3- to provide H + and lower blood pH. Carbonic acid, which can be formed from bicarbonate, is converted to CO2 and water by a very fast enzymatic reaction. CO2, being volatile, can be rapidly eliminated from the body in variable amounts through respiration.In the clinic, the system that is measured for the assessment of the acid-base status is the carbonic / bicarbonate system.

1. There are 2 types of rabbits in a population: those that eat grass, and those that eat flowers and berries. One
year, a drought occurs, and the plants have a hard time producing extras such as flowers or berries. They
can only try and keep themselves green. All year the rabbits have had babies, but many get eaten by
predators like foxes and hawks. Due to the drought, though, many have also starved. Explain what type of
natural selection will occur to this population of rabbits, including what trait is selected FOR and which is
selected AGAINST, and how the population will evolve as a result of the natural selection.
Answer:
Answer:
Against: rabbits that eat berries or flowers
For: grass eating rabbits
Explanation:

Comment /free for a giveaway entry of 20 thanks and 2 brainliest. Have an awesome day! Let me know if you have any questions! -KaraYeaton18
Answer:
I'll explain it to make it easier on you :)
Explanation:
This type of natural selection is called disruptive selection. Because of the drought, foxes, hawks, and other animals eating the rabbits, the population of them is being disrupted Think of when a student is being disruptive in class. The teacher usually has to stop the class to 'punish' the student. This situation is similiar. There are things disrupting production and population of the rabbits.
FOR: The population of rabbits
AGAINST: The drought and predators
As a result of disruptive natural selection, the population of rabbits will only decrease due to predators and the drought.
I hope this helps you! :)

Which statement explains why desert plants close stomata during the day but open them at night?
A. Closing leaf stomata during the day and opening them at night makes the plants less vulnerable to attack by herbivores.
B. Stomata open at night because there is more carbon dioxide in the atmosphere available for photosynthesis and close during the day to prevent water loss.
C. Closing the leaf stomata during the day decreases the loss of water needed for photosynthesis while opening the stomata at night when the air is cooler allows the plant to take in and release gases.
D. Stomata open at night in order for the energy collected during the day to be used in several reactions and close during the day in order to release carbon dioxide during photosynthesis.
Answer:
the answer is C
Explanation:
Stomata are pores localized in the plant epidermis whose function is to regulate gas exchange between plants and the atmosphere. Generally, stomata open during the day to allow the diffusion of carbon dioxide (CO2) and close during the night to avoid water loss (i.e., transpiration). On the other hand, CAM plants photosynthesize during the day, and exchange gases (CO2 and O2) during the night. Thus, desert CAM plants open their stomata during the night and close them during the day hours. These desert plants open stomata at night to absorb CO2 and close them during sunlight hours to prevent transpiration.

d.
All the body cells arise from mitotic divisions of the same fertilized egg.
Answer: d. All the body cells arise from mitotic divisions of the same fertilized egg.
Explanation:
After conception occurs and an egg is fertilized, mitosis takes place as the egg begins to divide into other cells. This is how all the cells in the body are eventually formed regardless of how specialized their roles are.
As a result, every cell in the human body shares the same genes so any biological liquid or structure of the body would indicate the criminal because they would share the same gene as the rest of the cells in the criminal.

Which organism will have DNA most similar to the turtle?
Answer:
the answer is leopards!
Explanation:
I answered a similar question like this yesterday,
Hope it helps!!
The organism that will have DNA most similar to the turtle's will be other reptiles, particularly those in the same order as turtles, which is Testudines, which is present in Option A.
What is DNA sharing among ancestors?Organisms that are closely related evolutionarily tend to have more similar DNA sequences than those that are more distantly related because they share a more recent common ancestor and have had less time to accumulate genetic differences. Turtles belong to the class Reptilia, which includes other reptiles like lizards, snakes, crocodiles, and birds. Within the reptile class, turtles are classified under the order Testudines, and other members of this order include tortoises and terrapins that share common characteristics with turtles.
Hence, the organism that will have DNA most similar to the turtle's will be other reptiles, particularly those in the same order as the turtles present in Option A.

What part of the nucleotide determines the code of a DNA molecule
Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
The nitrogenous bases as a part of the nucleotide is what determines the code of a DNA molecule.
WHAT IS DNA:DNA, also called deoxyribonucleic acid, is a biological molecule that stores genetic information in living cells. DNA is a polymer molecule that is made up of monomers called nucleotides. These nucleotides further comprises of nitrogenous bases, phosphate group and pentose sugar. The nitrogenous bases are Adenine, Guanine, Thymine and Cytosine.

Evergreen broadleaf trees, along with abundant rain, warm temperatures, and consistent day length, characterize the _ biome.
Answer:
Rainforest biome (tropical rainforest)
Explanation:
The characteristics of the tropical rainforest biome are:
Located in humid and warm regions of equatorial climate.Medium temperature among 18 and 30 ºCAnnual precipitation is around 1000 and 8000 millimeters. Precipitation levels are never inferior to 1500 mm. There is no dry season, or if there is, it is too short. There is no hydric deficit. Fanerophic species dominate in this biome. Evergreen tall trees might reach up to 50 meters in height. They develop dense foliation and branches, becoming a refuge and source of food for many species. Vegetation does not need to develop strategies for surviving the dry season. Instead, they need to develop strategies for competing for light and nutrients. We can find different species of plants such as epiphytes, lianas, stranglers, aerial-rooted pants, tabular-rooted plants, among other vegetation forms. Tropical and subtropical rainforests might differentiate from each other in latitude and seasonality. Tropical rainforests might be found in latitudes of the Capricorn and Cancer tropics. From cero to ten degrees latitude. They are in America, Africa, and Asia continents. It is the biome with the greatest biodiversity on the planet. Rainforests have an extraordinary richness of animals and plants.
