Which of the following are NOT ways that viral vectors are modified to be made safer?
a. deleting virulence genes
b. avoiding genome insertion next to oncogenes
Answer:
eliminating virulence genes would be the correct answer
Explanation:
The correct answer was that since if the relationship between viruses and oncogenes is modified, the release of the oncoprotein is avoided, as well as the presence of malignant neoplasms before viral infections such as: epstein barr virus and kaposi's sarcoma.
So my answer is that the virulence factors of a virus cannot be modified to make viral vectors safer, the viral vector would be human and this is safer if its protoncogenes do not become oncogenes due to viral infections.
PLEASE ANSWER I NEED HELP In a family, the father is affected by a genetic disorder. The son in the family has the same disease, but the daughters do not have it. What type of inheritance is this? A. Y-linked B. X-linked C. polygenic D. codominant
A. Y-linked.
Explanation:
Males have one Y chromosome and one X chromosome, while females have two X chromosomes.
If the father is affected by a genetic disorder, that means it will be passed down to only sons in the family, not females, since females do not have a Y chromosome.
This would mean the genetic disorder is Y-linked, and only on the Y chromosome, which is specific to males.
Answer:
A. Y-linked
Explanation:
Males have one Y chromosome and one X chromosome.
Females have two X chromosomes.
Father is affected by a genetic disorder. The son has the same disease. The daughters are not affected because they do not have Y chromosomes.
The father and son have Y chromosomes, so the type of inheritance is Y-linked.

Rarely, the conjugation of Hfr and F− cells produces two Hfr cells. Explain how this event takes place.
Answer:
"F" on account of E.coli show the fertility factor. Cells possessing this factor (called donors) hold the ability to move the hereditary material over the strains by a procedure called conjugation. F-factor exists as a free element (cell is called episome) or integrated into bacterial chromosome (cell is called Hfr-High frequency recombinant). Cells with no F factor are recipients.
In a Conjugation between a F+ and F-cell just F factor from F+ cell gets moved o produce two F+ cells. But during a Hfr and F-conjugation as the F factor is incorporated into the chromosome and by the intrinsic idea of F factor to get moved the Hfr cells attempt to move their whole genetic material across and there are two outcomes wherein one case there is a fragmented exchange of hereditary material and the recipient cell remain F-and when there is a finished exchange of hereditary material the cell becomes Hfr yet this is uncommon as the time taken for the total exchange of hereditary material is excessively long for the cells to remain contact.

When DNA is replicated, the two strands are first separated through _________; each strand then becomes a _________ against which two new strands are made.
Answer:
Answered below
Explanation:
Deoxyribonucleic acid, DNA, replication is the process whereby DNA makes a copy of itself and it occurs during cell division.
When DNA is replicated, the two strands are first separated through unzipping at the origin of the replication fork. This is catalysed by the enzyme helicase. Helicase breaks down the hydrogen bonds which hold the complementary base pairs of DNA together.
Each strand of DNA to then becomes a template against which two new strands are made. One of the strands is called the leading strand and the other is called the lagging strand. Both are oriented in opposite directions.
Which of the following is NOT a negative effect of the way we use science? A. Climate Change B. Damage to the sun C. Pollution D. Overuse of resources
Answer: Option B.
Damage to the sun
Explanation:
Damage to the sun is not a negative way we use science because the sun is very far away from the Earth. The sun is so far away that light from the Sun, traveling at a speed of 186,000 miles (300,000 kilometers) per second, takes about 8 minutes to reach us. This means that The distance from the sun to the Earth is far and it's difficult for science to have negative effects on the sun. The sun is not easily accessible and sun damage is not easily affected compared to pollution, climate Change, overuse of resources which it's as a result of science negative effect.

how were the designs Pasteur's and Redi's experiments different?
Answer:
Francesco Redis experiment was conducted in 1668. His experiment was centered around the idea that maggots will arise from rotting meat. He conducted an experiment through his hypothesis that the maggots actually came from eggs laid by flies on the meat. To prove this he placed a piece of meat on 3 separate jars. He left one of the jars completely open, another sealed, and another covered by gauze. His hypothesis was proved to be correct when the only piece of meat that had maggots was the one that was left open.
Louis Pasteurs experiment was conducted in 1858. His experiment was influenced by a similar failed experiment conducted by Lazzaro Spallanzani in 1768. He was trying to prove that the air was not what was making the broth cloudy but what was actually making it cloudy was tiny microorganisms getting inside. To prove this, he created a swan neck flask that allowed air to come inside but trapped the microorganisms in a pocket on the flask.
Differences:
Redi used meat in his experiment while Pasteur used broth.Redis experiment was to disprove Aristotles idea that some life forms arise from non living matter. while Pasteurs experiment was to disprove the idea that air gives life force.Redis experiment was conducted in jars while Pasteurs was conducted in a hand made swan neck flask.Explanation:

12. You are spraying your garden with a pesticide and you accidentally swallow a small amount. You read on the package that this pesticide inhibits ATP synthase. Should you be worried
Answer:
Yes
Explanation:
The ATP synthase is an enzyme that catalyzes the synthesis of adenosine triphosphate from adenosine diphosphate (ADP) in the body of living organisms. The ATP is the energy currency of the cells, without it, metabolic processes will not be able to proceed. ATP synthase helps add inorganic phosphate (Pi) to ADP in order to generate ATP.
[tex]ADP+Pi+ energy -->ATP+H_2O[/tex]
Hence, if the pesticide is known to inhibit ATP synthase, it means that ATP synthesis will be disrupted and the cells of the body will not be able to get the required energy to carry out their normal metabolic activities.
There is a genuine reason to be worried and I should be looking to get medical help as soon as possible.
Which of the following statements correctly describes some aspect of ATP hydrolysis being used to drive the active transport of an ion into the cell against the ion's concentration gradient? (see book section: Concept 8.2: The free-energy change of a reaction tells us whether or not the reaction occurs spontaneously and see book section: Concept 8.3: ATP powers cellular work by coupling exergonic reactions to endergonic reactions)
A) The hydrolysis of ATP is endergonic, and the active transport is exergonic.
B) This is an example of energy coupling.
C) Both ATP hydrolysis and active transport are spontaneous because they result in an increase in entropy of the system.
D) Neither ATP hydrolysis nor active transport is spontaneous.
E) ATP is acting as a transport protein to facilitate the movement of the ion across the plasma membrane.
Answer:
B) This is an example of energy coupling
Explanation:
Energy coupling is a process by which cells carry out thermodynamically unfavorable, endergonic (energy-requiring) reactions to other exergonic (reactions that liberate free energy) reactions.
Reactions which are endergonic do not occur spontaneously as they result in a decrease in entropy and a positive free energy change, ∆G.
Exergonic reactions occur spontaneously as they result in an increase in entropy and have a negative free energy change, ∆G.
For example, the active transport of ions against their concentration gradients in cells is a non-spontaneous endergonic process which is coupled to the hydrolysis of ATP, an exergonic process in other for the reaction to proceed. ATP hydrolysis phosphorylates an amino acid side chain in the transport protein which then drives the forward process of transport of the ion.
Considering the above,
Option A: The hydrolysis of ATP is endergonic, and the active transport is exergonic is false because ATP hydrolysis is exergonic while active transport is endergonic.
Option B: This is an example of energy coupling is true.
Option C: Both ATP hydrolysis and active transport are spontaneous because they result in an increase in entropy of the system is false because only ATP hydrolysis is spontaneous
Option D: Neither ATP hydrolysis nor active transport is spontaneous is false because ATP hydrolysis is spontaneous.
Option E: ATP is acting as a transport protein to facilitate the movement of the ion across the plasma membrane is false because ATP is not a protein, rather it serves to activate the transport protein by phosphorylating it.

What Happened to My Garden?
Bill’s grandparents have had a garden for as long as he could remember. As they got older, he helped them with the heavy lifting, moving dirt, digging potatoes, etc. But they still did most of the work, and reaped the fruits and vegetables of their labors most years.
But this year was different. His grandparents’ peppers, kale, potatoes, and other vegetables were not only not thriving, they were dying – all of them. It had been an exceptionally wet year; usually they had to water everyday, but there had been enough rain to limit watering. In addition, Bill had set them up with a catchment system to catch and collect rainwater off the roof of their house. They had been using this to water the plants this year. His grandparents thought this water might be affecting their crops, or maybe it was the hailstorm they had early in the season. They had always saved seeds to replant every year, so that shouldn’t be a problem, should it? They also had new neighbors who had planted a garden right across the fence. They were a young family, just moved in, and they started their garden a bit late, but his grandparents were giving them advice.
What do you think could be causing Bill’s grandparents’ garden to die off? Describe a few possibilities.
1. They might be using the wrong kind of soil for the plants, causing them to die.
2. The new neighbors could be adding something toxic to Bill's grandparents' plants.
3. Maybe what the neighbors are adding to their garden is affecting Bill's grandparents' garden on the other side of the fence.
The things that are causing Bill’s grandparents’ garden to die off include microbe and new plant species by the neighbor.
There may be microbes in the rainwater that was collected. In this case, the microbes could have infected the plants and thus will have affected the growth of the plants.
Also, the new neighbors may have brought in new plant species and this may have had adverse effects on the plant. In such a case, it may have led to the death of the plants.

Explain how fossils were used to develop early geologic time scales.
Answer:
Fossils refer to the remains of the past life like shells, bones, or other tough parts, and it may also comprise the proof of past life-like leaf impressions or footprints. A geologic time scale refers to the timeline, which demonstrates the past time of the Earth.
The planet in which we live is very old, and the study of the past of the Earth needs one to think about the times, which were millions or billions of years old. The geologic time scale is used by scientists to explain how the incidents took place on Earth.
The development of the geologic time scale was done after scientists witnessed certain modifications in the fossils that took place from the oldest to the newest sedimentary rocks. The phenomenon of relative dating was used to differentiate the past of the Earth in many parts of time when the same organism was there on Earth.
