Answer:
a, b, c, e
Explanation:
- since mutations are random, they could both harm or benefit or have no effect on the organism (depends on where in the DNA is mutated, on the type of mutation that occurs, on whether the mutation is fixed, etc.)
- the binding between codons and anticodons are always as follows:
A on mRNA binds to U on tRNAT on mRNA binds to A on tRNAG on mRNA binds to C on tRNA and vice versaMutagens are substances that damage DNA and can cause permanent changes in the DNA sequence, depending on the ability of the organism to fix the mess.
Mutagen's effect:Deoxynucleoside triphosphates (dNTPs), which are utilized by DNA polymerases to duplicate DNA, can also be damaged by DNA-damaging agents.
A mutagen could harm the organism by disrupting gene function.A mutagen may alter gene function to the organism's benefit.A mutagen can alter codon-anticodon binding.Therefore, the final answer is "Option A, B, and D".

Which of the following are contributions of deforestation to global climate change? Select all that apply.
Conversion of forest to cropland or pasture decreases the rate at which carbon is taken up by plants.
Cut trees are often burned, and this releases carbon into the atmosphere.
Clearing of forests increases the leaching of nutrients in affected regions.
Deforestation increases the risk of landslides in cleared regions.
Answer:
Conversion of forest to cropland or pasture decreases the rate at which carbon is taken up by plants.
Cut trees are often burned, and this releases carbon into the atmosphere.
Explanation:
First of all, deforestation is the conversion of forests to non-forest uses. Non-forest uses include agriculture, industrial development, infrastructural development, etc.
Forests are sinks for carbon and their removal or conversion to non-forest uses means that less carbon would be fixed through photosynthesis. Slash and burn agricultural practice also leads to the emission of carbon dioxide into the atmosphere.
Thus, more carbon dioxide would be present in the atmosphere as a result of deforestation and burning. This carbon dioxide is a greenhouse gas that causes the warming of the planet, a phenomenon that results in the change of climate of the planet.
Hence, the conversion of forest to cropland leading to a decrease in the rate of carbon fixation and the emission associated with burning both contribute immensely to global climate change.

which of the following correctly describes compact bone and cancellous bone. A) only compact bone has osteocytes. B) compact bone has osteons and cancellous bone has trabeculae. C) compact bone forms the inner part of the bone and cancellous is the outer part. D) cancellous bone is extremely dense and strong while compact bone has many open spaces where bone marrow is found.
Answer:
A.) Only compact bone has osteocytes.
Explanation:
Reasons why B C and D are incorrect
B the cancellous bone doesn't have trabeculae,there for the statement is incorrect.
C.The compact bone is on the "OUTER" part of the bone,so that would be incorrect
D. The cancellous bone is much more porous and, therefore, weaker than the compact bone.
The statement that correctly describes compact bone and cancellous bone is that compact bone has osteons and cancellous bone has trabeculae. That is option B.
The bones makes up the musculoskeletal system of the body. It provides framework of the body and gives attachment to muscles and tendons.
There are two types of bones:
The compact bone: This makes up about 80% of the body bone mass. It is made up of a large number of tube-shaped units called osteons. The way the osteons are aligned in the bone, gives it great strength.The cancellous bone: This is also called spongy bone. This is because it looks like a honeycomb. There are presence of little beams called trabeculae which consists of a few lamellae and osteocytes interconnected by canaliculi.Learn more here:

In the soybean respiration experiment, why were glass beads added in the non-germinating seed tube?
Answer:
Explanation:
The result was a decrease in gas volume within the tube, and a related decrease in pressure in the tube. The respirometer with just the glass beads served as a control, allowing changes in volume due to changes in atmospheric pressure and/or temperature.
The purpose of the beads is to ensure that each respirometer is uniform in volume. The vial with glass beads alone will permit detection of any changes in volume due to atmospheric pressure changes or temperature changes.

In an analysis of the nucleotide composition of DNA, which of the following proportions will be found?
to. A + C = G + T
b. G + C = T + A
c. C = C
d. A = G and C = T
Answer:
With respect to the composition of DNA, in an analysis it can be found that the proportions of nucleotides are A + C = G + T (option a).
Explanation:
The proportion of nucleotides in a DNA molecule can be established according to the sequence of these nucleotides on both complementary strands, since the purinic bases of one strand are complemented by the pyrimidinic bases of another:
Adenine is complemented with Thymine A=TGuanine is complemented with Cytosine G=CFrom this we can deduce that in a DNA molecule with two chains there will be the same amount of adenine and thymine, as well as the same number of guanine with respect to cytosine, so:
A + C = G + T
An example of this would be a known DNA molecule (hypothetical), with 5 molecules of Adenine and 7 molecules of Guanine. In this case there are 5 Thymines, complementary with Adenine, and 7 Cytosines like Guanine:
A + C = G + T
5 + 7 = 7 + 5

If a cell suddenly stopped producing transfer RNA, which of the following processes would be immediately affected?
A) MUTATION
B) REPLACATION
C) TRANSCRIPTION
D)TRANSLATION
Answer:
D
Explanation:
If a cell suddenly stopped producing transfer RNA, the process that would be immediately affected is translation. The correct option is D.
What is translation?The translation is the second step of the process of protein synthesis. In translation, the RNA give instruction to the ribosomes, and they produce protein.
The first step in protein synthesis is transcription, in which the DNA gives its template to produce RNA. The RNA then in translation produces protein. The translation is divided into three steps. They are initiation, elongation, and termination.
Initiation starts the process and elongation runs the process. The termination gives the stop codons to stop the process. The codons are the codes of genetic codes.
Thus, the correct option is D. translation.

Answer:
I think it's 6
Explanation:
During cellular respiration, one molecule of glucose is recycled into 6 molecules of carbon dioxide.
Cellular respiration refers to series of metabolic reactions that typically occur in living cells, in order to produce energy in the form of adenosine triphosphate (ATP).
Generally, the whole metabolic process involved in cellular respiration can be represented by using a single chemical equation with the following substances;
Glucose.Oxygen.Carbon dioxide.Water.Adenosine triphosphate (ATP).[tex]Glucose + Oxygen ---> Carbon \;dioxide + Water + ATP[/tex]

Answer:
The appropriate response is Kussmaul breaths. Kussmaul breaths are just seen in those with DKA. Kussmaul breathing is the body's endeavor to pass over, however, much carbon dioxide as could reasonably be expected to keep in mind the end goal to adjust for the metabolic acidosis from DKA. C.

A)
use the acid test
B)
see if it breaks into sheets
C)
see if it is attracted to a magnet
D
compare the color to other minerals
Answer:
The correct answer is - a) use the acid test.
Explanation:
In this chart, there are many minerals that share different properties with one another such as hardness, color, and luster of the minerals so on the basis of physical properties the group of students can not be sure if the given mineral is calcite or not.
To be sure if the given mineral is calcite the group of students must test the acid test which is specific for the calcite and if the test produces bubbles it is confirmed that the given mineral among these minerals is calcite.
