Answer:heh
Explanation:
Aluminium , mass no = no of proton + neutron = 27
atomic no = no of proton = 13
no of neutron = 27 - 13 = 14
Nitrogen , mass no = no of proton + neutron = 14
atomic no = no of proton = 7
no of neutron = 14 - 7 = 7
Helium , mass no = no of proton + neutron = 4
atomic no = no of proton = 2
no of neutron = 4 - 2= 2
fluorine , mass no = no of proton + neutron = 19

The incidence of V. vulnificus infections is increasing, especially in northern parts of the United States, compared to 20 years ago. Can you think of any reason why this might be happening?
Answer:
The effects of climate change may be associated with the increased incidence of V. vulnificus infection
Explanation:
Vibrio vulnificus is a harmful bacterium that causes a serious disease due to eating contaminated seafood, which is the main cause of seafood-related deaths in the USA. V. vulnificus is naturally present in the flora of coastal waters around the world and this bacterium has been isolated from a variety of seafood (e.g.., fish, oysters, shrimp, etc). Epidemiologic studies have shown that the incidence of V. vulnificus infection has increased dramatically since 1996. During this same period, climate change has been responsible for the increase in salinity and temperature of the coastal waters (i.e., the natural habitat of this bacterium). In consequence, it is reasonable to suppose that the change in climatic conditions may be associated with the increased incidence of V. vulnificus infection.

Explanation:
1. Robin carries the trash from the house to the garbage can outside. Which statement best describes the science of what he did?
He would use less energy if he were to move the garbage faster
He used energy to carry the garbage.
He did not have to work because garbage is light.
He caused the garbage to have potential energy when it moved.
Answer:
He used energy to carry the garbage.
Explanation:
Energy is the ability to do work. When work is done, energy is expended during the process. Work is done if the force applied on an object moves that object through a distance.
In the case where Robin carries the trash from the house to the garbage can outside, work is done because, the force applied by Robin on the trash effectively helps to move the trash from inside the house to the garbage can outside the house. During the process of moving the trash, Robin expends or uses energy to do the work.
From the given options:
He would use less energy if he were to move the garbage faster is wrong because an increase in speed results in an increase in energy
He used energy to carry the garbage is correct because energy is the ability to do work
He did not have to work because garbage is light is wrong because as long as an object is moved a distance, work is done irrespective of the mass of the object.
He caused the garbage to have potential energy when it moved can only be true if he had raised the garbage from the floor to a height above the ground. However, he only moved it fro inside to outside the house.

Two different species of mammals competing for the same water source is an example of two organisms competing for an abiotic factor.
What is abiotic factor?
Abiotic factors refers to non-living physical parts of the environment that affect living organisms as well as the functioning of ecosystems. In the above example, water source is a non-living part of an ecosystem which is required by both organisms.
This leads to competition of two mammals so we can conclude that two different species of mammals competing for the same water source is an example of two organisms competing for an abiotic factor.

PLEASE SOMEONE HELP ME I’M REALLY STRUGGLING
Answer:seventy-seven thousand years ago, a craftsman sat in a cave in a limestone cliff overlooking the rocky coast of what is now the Indian Ocean. It was a beautiful spot, a workshop with a glorious natural picture window, cooled by a sea breeze in summer, warmed by a small fire in winter. The sandy cliff top above was covered with a white-flowering shrub that one distant day would be known as blombos and give this place the name Blombos Cave.
Explanation:
Sickle cell anemia and albinism are both recessive traits in humans. Imagine that a couple, already pregnant with fraternal twins, has just learned that they (the couple) are both heterozygous for both of these traits. As the couple's genetic counselor, the couple asks you what is the probability of having both of the twins be albino and have sickle-cell anemia.
Answer:
81/256
Explanation:
By doing a test cross of albinism and sickle cell anemia you'll see that the probability that one child is unaffected by either conditions will be 9/16. Both children would be 9/16 * 9/16.
Since fraternal twins are developed from two separate fertilization events the probability chance will be independent.

What is the correct "height" or "size" for a piece of oils rigs to become a candidate for "rigs to reef." Remember, oil rigs can be cut into different sizes or parts.
Answer and Explanation:
An oil rig is a type of piston ring which is situated in the ring grooves. The oil ring is commonly used on small engines to wipe excess oil from the wall of the cylinder during the piston's movement. Through the opening of rings, excess oil returned to the oil reservoir. These rings are not used on the two-stroke cycle engines. These rings are one-piece or two-piece. An oil ring seals the combustion chamber through inherent pressure and controlling the consumption of oil. The inherent pressure of the oil ring is very high on the piston. These rings use an expander, high-pressure unit and inherent pressure. The oil rings are also used to spread the oil around the liner surface. These rings can be cut into various sizes. An oil ring has an axial.

Explanation:
You plan to clone a guide RNA sequence into the pML104 plasmid because you want to engineer the construct in bacteria and later express it in yeast. Unfortunately, your lab does not have any available pML104. Your friend in the lab next door lets you borrow a related plasmid pML107, and you quickly start your experiment. Will it work? Briefly explain.
Answer:
Yes, the experiment will work.
Explanation:
The reason behind this is that plasmids are well known to be DNA vector carriers. These plasmids have the ability to bring about changes in DNA fragments into various microorganisms and reveal them. The two plasmids compose of the same genomic marker such as the antibiotic resistance gene found in URA3. However, plasmids are most commonly found in bacteria, but also in eukaryotic cells. Oftentimes, the gene composition in the plasmids enhances the bacteria with a vantage edge such as antibiotic resistance.
Hence, it is obvious that in both, the molecular regulation in terms of expression of genes is alike in properties. Similarly, the numbers of copies and molecular weight are also the same.
We can thereby conclude that, provided that there is a proper restriction site, another host that is up to standard for plasmid can be replaced for each other.
A disease infects an organism, causing the organism's cells to have less chloroplasts. How will the organism be impacted by having less chloroplasts?
The organism will have less chlorophy reducing its ability to collect energy
The organism will have less cellulose, reducing its ability to remove waste
The organism will absorb less oxygen, reducing its ability to produce sugar
The organism will absorb less water, reducing its ability to create DNA
Answer:
the organism will have less chlorophyll
Explanation:
chloroplasts contain chlorophyll
Chlorophyll is a green pigment, without it a plant is discolored meaning it lacks of chlorophyll. Less photosynthesis would occur, and less glucose is made as a result. There is less energy released for growth as glucose is needed for respiration.

The color of a light wave is determined by its wavelength. On the COLOR tab, slowly drag the Light wavelength slider back and forth and observe the effect on oxygen production. How does the color of light affect the rate of photosynthesis
Answer:
The color of light determines how effective chlorophyll pigment will be at absorbing light.
Explanation:
Photosynthesis is a metabolic process that requires light, which is an electromagnetic radiation. Light on the electromagnetic spectrum is determined by wavelength. Each region/color of light occurs at a specific wavelength.
Hence, chlorophyll pigment, which is the major photosynthetic pigment effectively absorbs blue and red light in the visible light region of the electromagnetic spectrum. Hence, the rate of photosynthesis will be affected negatively if the color of light is not the one stated above.

(20 POINTS) How would your body repair a skinned knee?
Answer:
As soon as you cut or scrape skin anywhere on your body, special blood cells called platelets spring into action. Platelets stick together like glue at the cut, forming a clot. This clot is like a protective bandage over your cut that keeps more blood and other fluids from flowing out.
