Answer:Human plasmid can mutate
Explanation:
a) Explain why antibiotics would kill a prokaryotic cell. (2 points)
Answer:
Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors. For example, streptomycin stops protein synthesis in prokaryotic cells by binding to their unusual ribosomes.
Explanation:
Sorry if this makes no sense. Basically, the antibiotics will harm/kill cells like the prokaryotic cell, but it won't harm or kill any human cells that are essential. They'll kill bacteria, though. The chemicals in the antibiotics aren't compatible with the ones in the prokaryotic cell, so it'll kill it.

Summary of natural influences of a savanna.
Answer:
The African savanna ecosystem is a tropical grassland with warm temperatures year-round and with its highest seasonal rainfall in the summer. The savanna is characterized by grasses and small or dispersed trees that do not form a closed canopy, allowing sunlight to reach the ground. The African savanna contains a diverse community of organisms that interact to form a complex food web.

Yellow light travels through a certain glass block at a speed of 3 * 108 m/s . The wavelength of the light in this glass is 3.81 * 10 - 7m . What is the frequency?
Answer:
f = 7.87×10¹⁴ Hz
Explanation:
Given data:
Speed of light = 3×10⁸ m/s
Wavelength of light = 3.81 ×10⁻⁷ m
Frequency of light = ?
Solution:
Formula:
Speed of wave = wavelength × frequency
Now we will put the values in formula.
3×10⁸ m/s = 3.81 ×10⁻⁷ m × f
f = 3×10⁸ m/s / 3.81 ×10⁻⁷ m
f = 0.787 ×10¹⁵ s⁻¹
s⁻¹ = Hz
f = 0.787 ×10¹⁵ Hz
f = 7.87×10¹⁴ Hz
After basketball practice, Tyler began feeling a sharp pain in his knee. He visited the doctor and found out that he had torn one of the many ligaments in his knee. Which of the following best describes the function of the ligament he injured?Immersive Reader
(1 Point)
A. Connecting cartilage to muscles
B. Cushioning the ends of bones
C. Connecting bones to other bones
D. Connecting muscles to bone
Answer:
C. Connecting bones to other bones
Explanation:
Ligament is one of the connective tissues in living systems whose primary function is to connect bones to other bones. Ligaments are made up of a short band of tough fibre making it adapted to that connective function.
In this question involving Tyler who is diagnosed to have torn one of his knee ligaments, it means he has torn one of the many connective tissues that connects his bones to another bone in the knee.

Most of the oil and natural gas used today formed where forces within Earth folded and tilted thick rock layers.
O True
O False
The correct answer is true.
Most oil and natural gas formed where forces within Earth are folded and tilted thick rock layers, and they are also formed with plankton in which is concealed with sediment (a natural & solid material that is fertile to enrich nutrients in soils).
I hope this helps you, have a great day. :)

Which of the following is an example of individual evidence when it comes to carpet?
Group of answer choices
fiber length
dye composition
the carpet padding
the type of fiber
Answer: the carpet padding
Explanation:
Individual evidences are simply refered to as properties of physical evidence that has to a high degree of certainty for a common source. For individual evidences, the suspect is being narrowed down to a single individual. Examples include fingerprints, toolmarks etc.
In the question above, the example of individual evidence when it comes to carpet will be the carpet padding. While other options such as fiber length, dye composition and the type of fiber can still relate to other things, carpet padding narrows it down to carpet.

Dr. Mrs. Brown has Rh+ blood, but her father is Rh-. What must her full blood type genotype be?
Answer:
Her full blood type genotype is Dd.
Explanation:
Rh (Rhesus) factor is a type of protein found on the outside of red blood cells. It is genetically inherited. An individual that has this protein is Rh-positive, and the one that doesn't is Rh-negative. The Rh-positive gene is dominant, while the Rh-negative gene is recessive. This means that a person must inherit at least one dominant (D) allele from their parents in order to be Rh-positive.
If Dr. Mrs. Brown is Rh-positive, and her father is Rh-negative, her mother must be Rh-positive (DD or Dd), as well. Her father has two recessive alleles (dd), which means that Dr. Mrs. Brown must have one recessive allele. Since she is Rh-positive, she must have one dominant allele. This makes her genotype Dd.
What fusion process is occurring in the star Procyon B?
Answer:
Procyon B's progenitor star most likely had around 2.59 solar masses. Estimates suggest that the star spent about 680 million years on the main-sequence, fusing hydrogen in its core. It evolved into a giant and lost much of its mass due to stellar winds
Explanation:
Can you make a link between naturally occurring carbon molecules being called "organic" and food grown without chemicals being called "organic"?

What is the role of an enzyme in a reaction with the reaction ? would the reaction happen without an enzyme?
Answer:
Enzymes are not used up in a chemical reaction. Usually, the enzyme will “reset” and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction.
Explanation:
Enzymes serve a similar purpose for chemical reactions in an organism's body, which is to lower the amount of "activation energy" needed for a particular chemical reaction to occur. Without enzymes, many chemical reactions would occur at a much slower rate because the amount of activation energy required would be far greater.

In a farm, soy beans were the only crop that was planted on several hectares of land. A farmer noticed fungus was growing all over the soy bean fields. Predict what might happen to the soy beans and the fungus.
Thanks!
Answer:
The soybean and the fungus might die because both of them are depending their lives on the said crop and both of them are having competition in having the nutrients for their survival.
The soy beans might be damage and the products of the farmer will decrease.Hope this helps and if you could mark this as brainliest. Thanks!
What process is similar in both fermentation and cellular respiration?
electron transport chain
aerobic ATP production
glycolysis in the cytoplasm
hydrogen ion pumping
Answer:
glycolysis in the cytoplasm
Explanation:
~ Fermentation and cellular respiration are alike in that they both begin with a series of reactions known as glycolysis, which breaks glucose molecules into smaller pyruvate molecules. They are also similar in that during both processes, ATP is produced for the cell to use.

Which chemical is released by (2) WBC's that produces a non-specific inflammatory response?
Answer:
cytokines
Explanation:
Non-specific immune responses are integral to host cellular defense mechanisms. It is a general response, mediated by white blood cells, where cells rapidly react to pathogenic infiltration.
Here receptors on cells recognise molecules shared by a broad spectrum of pathogens, or even react to signals from damaged, injured or stressed cells like inflammatory cytokines in a cytokine storm.
