Some advantages of the sexual reproduction include genetic variation. Genetic variation results into changes in the genetic material (DNA). Thus, the correct option is A.
What is Genetic variation?Genetic variation is the difference in the DNA (deoxyribonucleic acid) among individuals or the difference between different populations. The multiple sources of genetic variation include mutations and genetic recombination. Mutation is the changes in the genetic material of an organism which are the ultimate sources of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Genetic diversity is important because it gives the species a better chance of survival through variations. However, the genetic diversity can be lost from the species when the populations get smaller and isolated from each other, which decreases a species' ability to adapt and survive better in the condition.
Therefore, the correct option is A.

tRNA molecules bring a specific ________________ to the ribosome, according to the ______________. *
2 points
protein, mRNA anti-codon
protein, tRNA codon
amino acid, tRNA anti-codon
amino acid, mRNA codon
Answer:
tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.
The function of tRNA depends on the complementarity that exists between the mRNA codon and the anti-codon tRNA, in such a way that :
The pattern in the amino acid sequence of a protein is indicated by mRNA tRNA has a complementary anticodon, so it will only bring the specific amino acid that the codon encodes.In general terms, each mRNA molecule possesses the genetic code that indicates the amino acid sequence of a protein, and tRNA helps bring those amino acids to the ribosome for synthesis to occur.

A student was asked to compare a cell to a typical home. In this analogy, the cell mitochondria are like the (floor,furnace,or roof) and the cell membrane is like the (walls,doors and windows,oven orattic or garage)
Answer:

If A Plant Cell Were A House...
Cytoplasm
Vacuole
The Cytoplasm
would be the carpeting. The Cytoplasm is the goo that all the organelles reside in, and all the furniture and stuff in the house kind of sit there in the carpeting.
The vacuole would
be the closets and pantries. The vacuole holds random things that the cell needs, and closets and pantries can hold anything you feel like putting in them, like food or clothes.
Lysosome
Mitochondrion
The mitochondrion would be the kitchen. It produces energy for the cell to use, and the kitchen produces food, energy for humans.
Nucleus
Endoplasmic Reticulum
Rough
The nucleus would be my mom. The nucleus controls the cell, and my mom controls my house.
Ribosomes
The Smooth ER would be just plain hallways. The ER is a vast network of tubing that things the cell needs travel down.
The Rough ER would be hallways filled with cattle. This wouldn't be a very good example, because it isn't a very vast network. A lot of people travel down them, though! The Rough ER is like smooth, except with ribosomes.
If you had a herd of cattle in your yard, it would be them. If not, just the kitchen, like the Mitochondrion. Ribosomes synthesize proteins, and cattle make milk, which is full of protein. Also, in the kitchen you can make proteins with different types of dairy, like cheese or milk.
Smooth
Lysosome
Golgi (apparatus)
The Lysosome would be the trashcans, the recycle, and the compost. The Lysosome kills bacteria and holds it in plus other waste, and we dispose of our waste by putting it in one of the above options.
The Golgi (apparatus) would be my dad. The Golgi sorts and packages macromolecules to get them ready to transport. My dad does the same sort of thing, he's in charge of kind of organizing/sorting things around the house.
Cell Membrane
The Cell Membrane would be
the doors and the screens (on the windows). The cell membrane is a semi-permeable barrier, meaning that some things can get through and some can't. For example, only people who have the right key can open the door. Also, with the screens, air can get in, but flies and bees can't.
Chloroplast
Cell Wall
The Chloroplasts would be solar panels, if you had any, or houseplants if not. The Chloroplasts convert sunlight into energy, and both houseplants and solar panels do this same job.
If a cell were a house,
the walls, floors, and ceiling would be the cell wall because they keep everything in the house inside, just like the cell wall keeps all the organelles inside the cell.

How many cycles of β oxidation are required for the complete oxidation of activated oleic acid, 18:1(9)?
Answer:
The answer is "8 beta-oxidation cycles".
Explanation:
Please find the complete question in the attached file.
In this complete oxidation of active oleic acid 18:1(Δ9), 8 beta-oxidation cycles are required. Oleic acid is saturated fat, 9 to 10-carbohydrate fatty acid. Its double bonding is cis-focused. Its cycles for beta-oxidation required to oxidize an active oleic acid fully are 8.
It's initial two fatty acids are removed by oxidation in β - oxidation from the initial two carbon atoms. The recently formed carbon units are made up of creating temporary A molecules (acetyl- CoA). That cycle for oxidative begins with both the coffee grounds terminals of the fat lactone chain.
Is your prediction supported by the membrane potential chart? Explain your answer.
Answer:
Yes, it is. The chart shows that the initial charge of the neuron is negative. When the neuron is stimulated, sodium ions enter the cell. So, the voltage inside the cell changes to positive. When potassium ions move outward, the voltage decreases until it reaches its previous state.

Answer:
According to the image, the approximate QT interval is 0.4 seconds.
Explanation:
The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.
Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.
In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:
0.04 seconds X 10 mm = 0.4 seconds.
Then, the estimated QT interval is 0.4 seconds.
What is a vein in rock?
Answer:
Vein, in geology, ore body that is disseminated within definite boundaries in unwanted rock or minerals (gangue). The term, as used by geologists, is nearly synonymous with the term lode, as used by miners. There are two distinct types: fissure veins and ladder veins.
Explanation:
Material deposits known as geological veins are created when an existing rock fracture is filled with a new mineral.
How rock veins are formed?
They are fascinating to planetary scientists because they frequently reveal information about historical water flow. For instance, a lot of rocks have natural pores.
A vein in geology is a distinctive sheet-like body of mineral crystals embedded into a rock. When precipitation occurs, mineral components that are transported by an aqueous solution within the rock mass are deposited as veins.
Therefore, it is thought that aqueous solutions carrying different elements migrate through rock fissures and deposit their load onto the fissure walls when vein deposits occur, rising water that is hot.

What stages of replication do both cycles have in common? Describe the virion action at each of these stages.
Answer:
Attachment, Penetration and Replication
Explanation:
A bacteriophage is a virus that attacks bacterial cells. The lytic and lysogenic cycles are two methods of viral replication. In the lytic cycle, the virions produced are released from the host cell whereas in the lysogenic cycle, viral nucleic material are incorporated into host nucleic material and are copied to daughter cells when the host cell reproduces. The common steps in both cycles are given below:
1 Attachment – in this step, the bacteriophage attaches itself to the surface of the host cell so as to insert its DNA into the host cell.
2. Penetration – the virus inserts its DNA into the host cell by penetrating the cell membrane of the host cell.
3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism.

One of the reasons you might struggle to lift a heavy object with your arm fully extended is because:_______.
Answer:
the overlapping decreases between the thin and thick filaments.
Explanation:
When w extend our hand or arm to the full and try to lift any heavy object, we are unable to lift the object inspite of applying all our force. We struggle hard to lift the object with our fully extended arm because when we extend our arm fully it decreases the overlapping of our thin and the thick filaments of our muscles which makes it difficult to lift. In other words, the resting length of our arm is the optimal length to generate force.
