Answer:
A) how the temperature of water affects photosynthesis.
Explanation:
Photosynthesis is a process in which plants transform light into chemical energy. They require water and sunlight to grow. During the process light energy is absorbed by plants and they consume water, carbon dioxide and some mineral from soil to produce oxygen by a chemical reaction. Jared is also considering to analyse the different water temperatures. The higher temperature of water will enhance the rate of photosynthesis.
John complains of severe pain in the region of his left cheek which seems to increase when he chews on his food. A tense swelling is seen just anterior to his left ear. Which of the following structures do you think is the most likely cause of the problem?
1) submandibular salivary gland2) lingual tonsil3) palatine tonsil4) parotid salivary gland5) sublingual salivary gland
Answer:
Parotid salivary gland.
Explanation:
John's parotid salivary gland is the major cause of the problem
Parotid salivary gland is the largest of the salivary gland. Parotid salivary gland is found in the mouth, the upper part of the cheek and part of the ear.
This gland help to chew and empty saliva into the mouth.
A viral infection like flu, mumps can cause swelling of the parotid salivary gland.
Other symptoms include ;
Tender , lump cheeks.
Swollen cheeks
Difficulty in opening the mouth and swallowing food.
Pain in the left ear
Fever , chills and general weakness and so on.
Treatment of this depend on the type of infection, drinking hot water with lemon juice can help can help stimulate saliva.
Answer:
parotid salivary gland-parotitis.
Explanation:
This is located in front of and just below each ear.When the duct which drains this gland it blocked,drainage of saliva is prevented, and therefore lack of drainage leads to pain.
its inflammation is due primarily to bacterial infection,among other factors which are HIV,diabetes,etc.
Antibiotic intake is the most effective way of treatment.
In addition,the treatment is based on saliva stimulation to unblock the drainage. Therefore lemon intake either as raw or with water is ideal way.
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.

He inherited both due to the presence of XY chromosomes.
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.

to show a longitudinal wave with higher energy?
They would be farther apart.
They would be closer together.
O They would be shaped like a hill.
O They would be shaped like a valley.
Answer:
They would be shaped like a hill.
Explanation:
A longitudinal wave with higher energy have greater amplitude. Amplitude is the distance between the crust and trough of the wave. Crust is the upper part of the wave while trough is the lower part of the wave. If the distance between crust and trough of the wave is higher so the amplitude is also greater and we can say that the wave contains high amount of energy and vice versa. The shape of the wave just like a hill.

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:

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.

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.
