Which of the following statements is true?
A) Acquired mutations are passed down from parent to offspring.
B) Mutations are the only way to add new genes to a gene pool.
C) Hereditary mutations are caused by external factors, such as radiation.
D) Only somatic mutations are important to evolution because they can be inherited.
it's either b or a I just studied this I believe its b though I know it's not d becuade hereditary mutations are passed dow. from parents not outside sources and it's not d because it's not true
Acquired mutations occur in somatic cells and cannot be passed down to offspring, while only mutations in germ cells can be inherited and are relevant to evolution.
The question relates to our understanding of genetic mutations and how they play a role in heredity and evolution. Not all statements provided are correct, but the right answer in context of these options is not explicitly provided. To clarify: Acquired mutations are mutations that occur in an organism's somatic cells and are not hereditary, meaning they are not passed down from parent to offspring. On the other hand, mutations that occur in germ cells (sperm and egg cells) can be passed on, and these hereditary mutations are essential for the process of evolution because they can introduce new genetic information into a population. Additionally, while it is true that mutations are a source of new genes in a gene pool, they are not the only way new genes can be added; gene duplication and lateral gene transfer can also contribute to this.

How do earthworms get oxygen to their cells?
They breathe through their skin. Air dissolves on the mucus of their skin, so they MUST stay moist to breathe.
If worms dry out, they suffocate. As fresh air is taken in through the skin, oxygen is drawn into the worm's circulatory system, and the worm's hearts pump the oxygenated blood to the head area.
Earthworms breathe through their skin which contains mucus where the atmospheric air is dissolved. This dissolved air reaches the circulatory system which transfers oxygen to each cell in a random manner.
Why earthworms breathe through the skin?Earthworms breathe through their skin because for maintaining their surface body moist and slimy which is essential for their metabolic activities.
Therefore, it is well described above.

Why does dna rely on rna?Why can’t dna deliver the instructions to the ribosomes directly
Answer:
Why does dna rely on rna?
Transcription is carried out by the DNA-dependent RNA polymerase that replicates the series of the DNA chain into RNA. To start transcribing the sequence, the RNA polymerase binds to the series of DNA called the promoter and divides the DNA strands. It then copies the sequence series into the messenger RNA copy until it hits the part of DNA named the Terminator, where it halts and detaches from the DNA. As with being DNA-dependent DNA polymerases, RNA polymerase II, this protein that transcribes most of these factors at the human genome, controls as part of the huge protein structure with multiple regulatory and accessory subunits.
Why can’t dna deliver the instructions to the ribosomes directly
Transcription begins at the nucleus, which is the mind of the cell. It contains DNA which include all the messages we want to create proteins. These messages are taken by those ribosomes outside the nucleus. DNA is also valuable to be run in the cell, it wants to be there as a kind of professional material. Then this cell gets another copy of it in the process called transcription.
Because the DNA can't leave the nucleus to send it's information across to other organelles of the cell.
Deoxyribonucleic acid functions in the cellDeoxyribonucleic acid (DNA) is the genetic molecule of a cell that is found in the nucleus.
Ribonucleic acids (RNA) are equally genetic materials of the cell which has single-stranded chain of cells that processes protein. The types of RNA are:
messenger RNA (mRNA), transfer RNA (tRNA), andribosomal RNA (rRNA)DNA is responsible for storing and transferring genetic information, while RNA (messenger) directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins.
Therefore, because the DNA can't leave the nucleus to send it's information across to other organelles of the cell.

Certain bacteria produce a chemical that makes them resistant to penicillin. Since these bacteria reproduce asexually, they usually produce offspring that...?
Bacteria that produce a chemical making them resistant to penicillin typically pass this resistance on to their asexually reproduced offspring, increasing the proportion of penicillin-resistant bacteria in the population.
Explanation:Since these bacteria reproduce asexually, they usually produce offspring that are also resistant to penicillin. This resistance typically arises through a mutation that enables the bacteria to synthesize an enzyme called penicillinase, which can break down penicillin. This ability to degrade penicillin is especially concerning with bacteria like Methicillin-resistant Staphylococcus aureus (MRSA) that reproduce by growing and dividing into two, passing on the resistance trait to subsequent generations. One of the main reasons for the development of resistant bacteria is the overuse and incorrect use of antibiotics. The misuse, such as not completing a full course of prescribed antibiotics, leads to natural selection where non-resistant forms are eliminated and the proportion of resistant forms is increased in the population. Even when bacteria are separated by a filter that prevents cell movement but allows free exchange of cellular material, resistance can spread as sensitive bacteria acquire resistance through genetic mechanisms such as lateral gene transfer.

Juvenile Red Snapper are often found around natural or artificial reefs. If overfishing occurs in these areas, what would you predict will happen to the red snapper population?
The Red Snapper population will be affected greatly as juveniles will not reach adulthood to spawn.
The Red Snapper population will be affected marginally because this will only affect the juveniles.
The Red Snapper populations will benefit because the adults will have less competition from juveniles.
The Red Snapper populations will be unaffected unless they are specifically targeted by fishing.
Answer:
The Red Snapper population will be affected greatly as juveniles will not reach adulthood to spawn.
Answer:
Option A, The Red Snapper population will be affected greatly as juveniles will not reach adulthood to spawn.
Explanation:
The red snapper population is being fished during juvenile age and hence they do not grow into adults and produce offsprings.
The rate at which the juvenile offsprings are being killed is extremely high as compared to the rate at which they are reproduced as most of the red snappers are killed before they reach the age of fertility.
Due to this imbalance in the birth and death rates of red snapper, there will be tremendous decrease in the population of red snapper.
Hence, option A is correct.
what must be done to breed dogs for a particular trait
Answer:
Selective breeding
Explanation:
In order to get a dog that has specific desirable trait/s, then the owners of the dogs have to get involved. The involvement should be in the manner of only allowing dogs that have the same trait to breed between each other, but in no case to be allowed to breed with other dogs that do not posses that particular trait. In this way, the offspring will inherit the desirable trait from their parents, and if the selective breeding continues, then there will be a new dog type on the scene that will be unique by its trait/s.

Geologists conclude that the clasts in Layer A are older than the layer itself. Which geologic principle do the geologists use to draw this conclusion?
Answer:
Principle of inclusion
Explanation:
The principle of inclusion states that "fragments of rocks found in another rock is older than the rock itself".
This principle is very important for relative dating of rocks. It proposes that a rock containing inclusions or fragments of other rocks is younger than the fragments itself. This shows that the rock fragment was already in place before the current rock hosting it formed.
Some rocks can contain fragments of different rock types. The different rock types when encountered are older than the host rock. This is the principle of inclusion.
what cellular process releases energy by breaking down glucose when oxygen is not available
a. aerobic Respiration
b. The Calvin cycle
c. photosynthesis
d. Anaerobic Respiration
Answer:
d
Explanation:
because its food that i choke on
Answer:
d. Anaerobic Respiration
Explanation:
Living cells require energy to perform their various life functions. This energy is obtained by breaking down high energy storing food molecules in a process called CELLULAR RESPIRATION. Cellular respiration is a metabolic (catabolic) process that breaks down glucose to release carbondioxide, water and ATP (energy).
Cellular respiration can either be aerobic or anaerobic depending on whether oxygen is present or not. Aerobic respiration occurs in the presence of oxygen while anaerobic respiration occurs in the absence of oxygen. In the process of aerobic cellular respiration, Oxygen acts as a final electron acceptor in the ETC while in anaerobic respiration, another molecule other than oxygen e.g Sulfur acts as the final electron acceptor.
Some bacteria and yeast employs anaerobic respiration.

how does the presence of similar fossils on different continents support the idea of tectonic plate movement?
when the tectonic plates move the bones are carried from one place to another
The presence of similar fossils on different continents supports the idea of tectonic plate movement because it indicates that these continents were once connected in a landmass known as a supercontinent, and they have since drifted apart due to the movement of tectonic plates.
What are tectonic plates?Tectonic plates are large pieces of the Earth's lithosphere (the outermost solid layer of the Earth) that move and interact with each other. These plates can be thought of as giant puzzle pieces that fit together to form the Earth's surface.
When tectonic plates move, they can carry the continents they support along with them, leading to the separation of previously connected landmasses.
For example, the fossil remains of the freshwater reptile Mesosaurus have been found in both South America and Africa, which suggests that these continents were once connected.
The presence of the same species in two separate locations indicates that they were once a single population and that they were likely separated when the landmass they lived on split apart.
This observation supports the theory of continental drift and plate tectonics, which explain the movement of the Earth's continents over time.
