Answer:
What do you mean i'll help you but you need to be more specific
Explanation:
When water evaporates from plants through leaves, it diffuses through tiny openings called stomatal pores. If the water vapor needs to diffuse a distance L through one pore to exit the leaf in a time t, what is the time needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L
Answer:
L means same time.
Explanation:
Same time is needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L because the evaporation takes place at the same time in the pore and water is evaporated to the atmosphere but more water is evaporated due to increase of surface area as compared to the other pore that have small opening so the time is same but the amount of water evaporated is different.
Point mutations resulting in a single amino acid substitution provided evidence that: Select one: A. The genetic code is a triplet code. B. The genetic code is overlapping. C. The genetic code is not overlapping. D. The genetic code is degenerate. E. tRNAs recognize codons.
Answer:
C. The genetic code is not overlapping.
Explanation:
The genetic code is nonoverlapping because each nucleotide can be part of only one codon or 'codeword' during protein synthesis. Therefore, a particular point mutation in the nucleotide sequence can result in only one amino acid modification. A nonoverlapping genetic code indicates that the same letter (i.e., the same nucleotide) can not be used for two different codons. The non-overlapping nature of the genetic code was discovered by Tsugita and Fraenkel-Conrat (1960) by observing point mutations in the tobacco mosaic virus.
A change or modification in the single nucleotide base of the genetic material is called a point mutation. It can be either addition, deletion or inversion.
The correct answer is:
Option C. The genetic code is not overlapping.
This can be explained as:
The point mutation in the amino sequence tells that the codons are not overlapping and a single nucleotide is a part of only a single type of codon.A single nucleotide can't be included in two codons.The same letters of the bases purines and pyrimidines are not a part of two different triplets.Therefore, point mutation tells that the genetic code is non-overlapping.

what re stomata?how do they help leaves tomae food.
love you all
Answer:
Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.

Which of the following reasons for studying botany is most directly related to increased profits?
O Studying botany helps companies develop more abundant food crops for less investment.
O Studying botany can help us keep our forests healthy.
O Studying botany provides a chance to go on to graduate school.
O Studying botany tells us more about our place in nature.
Answer: Studying botany helps companies develop more abundant food crops for less investment
Explanation:
The reasons for studying botany that is most directly related to increased profits was that "Studying botany helps companies develop more abundant food crops for less investment".
Since more food crops are gotten for less investment, it ultimately means that there'll be a reduction in the cost which will hence lead to an increase in revenue and therefore there'll be an increase in profit.
As carbon dioxide is added to the atmosphere, more carbon dioxide also enters the ocean through diffusion. Carbon dioxide reacts with water to produce carbonic acid, which lowers the pH of the water. What effects do you think this might have on marine life?
Answer:
As the amount of carbon dioxide in the atmosphere rises, the oceans absorb a lot of it. In the ocean, carbon dioxide reacts with seawater to form carbonic acid. This causes the acidity of seawater to increase.
As we have seen, coral reefs have been bleached because of this increased in acidity
The oceans absorb a significant amount of carbon dioxide as the amount in the atmosphere increases. Seawater and carbon dioxide react in the ocean to produce carbonic acid. Seawater's acidity rises as a result of this.
What is acidification?Acidification is defined as a phenomena that happens when some chemicals release protons into the environment. Ocean acidification is mostly brought on by atmospheric carbon dioxide gas absorbing into the ocean. The pH of the water is lowered as a result, increasing the acidity of the ocean. The amount of carbon dioxide is rising due to numerous factors.
More carbon dioxide is evaporating into the ocean as a result of human-driven increases in atmospheric carbon dioxide concentrations. Currently, the ocean has an average pH of 8.1, which is basic (or alkaline), but when more CO2 is absorbed, the pH drops and the ocean turns more acidic.
Thus, the oceans absorb a significant amount of carbon dioxide as the amount in the atmosphere increases. Seawater and carbon dioxide react in the ocean to produce carbonic acid. Seawater's acidity rises as a result of this.

Using the concepts of chain of custody it is important to (multiple answer) A. document everyone who has handled the evidence prior to a trial B. record the dates and times of the possession of the evidence C. have a complete inventory of the evidence D. weight all of the evidence E. seal all of the evidence in air tight bags
Answer:
A. document everyone who has handled the evidence prior to a trial
Explanation:
A chain of custody can be defined as a paper trail containing the chronological order of items of evidence and how they have been handled, controlled, transferred, analyzed, and disposed during the investigation of a case.
This ultimately implies that, a chain of custody contains all the details or informations regarding the investigators (people) who handled, controlled, transferred, analyzed, and disposed an evidence in the course of carrying out investigations on a particular case. The most important and significant part of an investigation is the evidence because it helps to unravel the truth and facts relating to a case. Therefore, it is very important and essential to document and maintain a chain of custody so as to preserve the evidence.
Hence, using the concepts of chain of custody it is important to document everyone who has handled the evidence prior to a trial.

A plant and an animal are both living things. According to the Cell Theory, what can you conclude about these two
very different organisms? SC.912.L.14.1
Plants have cells but animals do not
They are both made of one or more cells.
They both come from the same kind of cell.
O They both come from a non-living organism.
Answer:
They are both made of one or more cells.
Explanation:
A plant and an animal are both living things. According to the Cell Theory, what we can conclude about these two very different organisms is that they are both made of one or more cells.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.

Pick out the sentences that correctly describe marine mammals.
Marine mammals are endothermic, or warm-blooded. Species such as whales breathe air though their gills. They have a thick layer of blubber
that helps maintain buoyancy. They can stay underwater indefinitely. Dolphins are a type of toothed whale. Baleen whales feed on large fish
and sometimes seals.
Marine mammals are endothermic. I think that's the correct answer 'cause they can produce their own body heat (which therefore means that they are warm-blooded) and they can keep at a stable temperature even in harsh conditions. Plus, whales don't have gills b/c they are mammals (and mammals don't have gills), not all mammals have blubber (it's mainly penguins and seals), marine mammals can stay underwater for a long amount of time...but they eventually need to come up for air, and baleen acts like a "filter"; it "filter" and separates the water from the krill/microorganisms.

Answer:
the first one: It has no antibodies that can attack the antigens on the red blood cells of the other blood types.
Explanation:
edge 2021
AB positive and O negative are considered as universal blood types. AB+ has no antibodies that can attack the antigens on the red blood cells of the other blood types. The correct option is A.
What is universal receiver?The people with AB+ blood group are called as the universal receivers. They can safely receive a blood transfusion using any other blood type. Having a universal blood type can save a life of yours or someone else in an emergency.
If you have an AB+ blood type, you have both A and B antigens. Since a person has all of the antigens that are possible, this blood type is the rarest. The AB+ blood type has a positive Rh factor, the recipient will not reject the blood. So it can get any type of blood.
AB type blood has no antibodies against type A or type B blood. So a person with AB blood can receive any type of blood.
Thus the correct option is A.
