Where in the cell is the rough endoplasmic reticulum located?
Answers
Answer:
Rough ER is named for its rough appearance, which is due to the ribosomes attached to its outer (cytoplasmic) surface. Rough ER lies immediately adjacent to the cell nucleus, and its membrane is continuous with the outer membrane of the nuclear envelope.

Two students are studying for a Science Test. On the table they had a glass of water and identical cell phones (Cell Phone A & Cell Phone B). Both of their phones had run out of battery, therefore they were both charging in the same wall outlet. Cell Phone A had a charging cord that was 3ft & Cell Phone B had a charging cord that was 9ft.

Some cells have multiple dendrites and/or axons. What advantages does this have for the nervous tissue?
Answers
Answer:
It receives information from several cells.
Explanation:
The main advantage of cells having multiple dendrites and/or axons is that it receives information from several cells as compared to those cells which have one dendrite and receive information from only one cell. If neurons have hundreds or thousands of dendrites, so these dendrites allow the cell to receive information from thousands of other cells. So we can say that dendrites number plays a key role in nervous tissue.

Answers
Answer:
B. Habitat
Explanation:
Ecosystems are geographical regions made up of biotic factors (plants, animals, bacteria) and non-living or abiotic factors (rocks, rainfall, temperature).
They live in groups called communities within their ecosystem and occupy a specific place in their community, a niche - here, they contribute to nutrient cycling and energy flow. They may often wander in search of food, or shelter in a region known as a habitat.
Which of the following scenarios can be classified as a negative feedback loop?
a increase in blood pressure to reduce heart rate
b increase in testosterone to help increase a fight-or-flight response
c increase in oxytocin caused by increased contractions
d increase in platelet production to help increase blood clotting
Answers
Answer:
The scenario that can be considered an example of a negative feedback loop is increase in platelet production to help increase blood clotting (option d).
Explanation:
Negative feedback loop is what occurs when a change occurs in the body, producing a response that decreases or stops that change, with the intention of maintaining homeostasis.
When there is a wound that produces bleeding, a series of mechanisms are activated, the coagulation cascade, which promotes the release of factors that allow the formation of clots. The increased release of platelets implies negative feedback because it helps to stop the change that occurs in the body, the loss of blood, through the formation of clots.
One thing that can cause confusion is the fact that this response also involves positive, though limited, feedback that promotes the production of clotting factors and platelets to increase clot formation. What really happens is that the positive feedback promotes the general feedback, which is the negative feedback: clot formation to stop the bleeding, restoring homeostasis.
The other options are not correct because:
a. Increase in blood pressure to reduce heart rate is not possible.
b. In the fight and flight response the hormones involved are cortisol and adrenaline, not testosterone.
c. Increased oxytocin in response to uterine contractions is positive feedback.

The survival of a species depends on its ability to adapt to changes in the environment. A species must be capable of surviving and reproducing despite changes to food sources, climate, or threats from predators. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment?
Mutations are always passed on to subsequent generations of the species
Mutations lead to genetic variation
Mutations are the cause of disease in the species
Mutations are not harmful when they occur in somatic cells of a species
Answers
Answer:
Your answer is B) Mutations lead to genetic variation.
Think of it like this, when rays were first starting to develop, they probably started with only one kind, stingless. Somewhere down the line, the genes of the rays started to mutate and eventually, there were stingrays and stingless rays. Now at this point there are predators that frequently feast upon the rays, so which of the two rays are more likely to defend themselves, and get away to live long enough to reproduce and pass on their genes? The stingrays! The mutation that may have occurred millions of years ago, has determined which organisms were more fit for a changing environment.
The survival of the species depends on the resources available and environmental conditions. The species or organisms capable to adapt to the surrounding have higher chances of reproduction and survival.
The correct answer is:
Option B: Mutations lead to genetic variation
The organisms adapting to the surrounding will undergo an alteration in their genetic sequence, known as mutations. The mutations are heritable and lead to genetic variation.
The mutation leads to genetic variation as:
It leads to the introduction of new alleles in the gene pool.Sexual reproduction and random mating also contribute to genetic variation. The mutations are heritable, and thus can cause an increase in the frequency of the mutated allele in the gene pool.
Thus, the correct answer is that mutation leads to genetic variation.

What do the results tell us about the experiment? The bacteria from all 3 farms were almost 100% alive in the control samples, meaning that the experiment did not work. None of the bacteria from the 3 farms survived in the control samples. Because the bacteria in the control were almost 100% alive, we know that any deaths of bacteria in the other samples was because of the antibiotics.
Answers
Answer: D
Explanation: The ones who are doing this on Gizmos the answer is D.
“Because the bacteria in the control were almost 100% alive, we know that any deaths of bacteria in the other samples was because of the antibiotics.” Y’all should like my answer n give me the brain answer.
The results tell us that in the experiment the death of the bacteria in the other samples was because of the antibiotics, confirming that the bacteria from the farms are sensitive to antibiotics.
What does it mean that the antibiotic is sensitive to bacteria?If a bacterium undergoes the action of an antibiotic, it is said to be sensitive; if, on the contrary, the antibiotic has no effect on the bacterium, it is said to be resistant. Resistance can be natural or acquired (eg, by plasmid transfer or mutations).
With this information, we can conclude that the results tell us that in the experiment the death of the bacteria in the other samples was because of the antibiotics, confirming that the bacteria from the farms are sensitive to antibiotics.

DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. The option (D) is correct.
What is DNA replication?
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Moreover, DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. All these cells, the parent cell and the two new daughter cells, are genetically identical.
Therefore, DNA replication is the process of creating two identical daughter strands of DNA. DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells. DNA replication occurs in S phase during the cell cycle prior to cell division.

What is gene expression?Gene expression is the procedure by which genetic information is utilized in the biosynthetic pathways of a functional gene product.
This aids in allowing it to produce end products such as protein or non-coding RNA as well as, as a result, affect a phenotype.
Several factors affect gene expression, along with molecules inside the cell, mutations that cause dominant negative effects.
It also cause haploinsufficiency, signaling molecules from neighboring cells and the surrounding environment, and epistasis. Several molecules within the cell influence gene expression.
The following process accurately describes gene expression: DNA is transcribed into RNA, which is then translated into protein.
