Calculate the force needed to cause a 6 kg bowling ball to accelerate 20 m/s2.

Due to the higher concentration of oxygen in the air than your blood, oxygen goes from the lungs into the red blood cells by simple diffusion.

It should be noted that oxygen diffuses from the lungs into the red blood cells. It then binds to hemoglobin. A molecule of hemoglobin can bind with four molecules of oxygen.

Since the red blood cells have cell membranes that are thin, this then enables oxygen to be able to diffuse quickly.

In conclusion, the correct option is simple diffusion.

The food that animals and people eat comes from a variety of sources, including plants, animals, and other organisms, as plants are the primary source of food for most animals, including humans.

They use photosynthesis to produce carbohydrates, proteins, and fats, which form the basis of their tissues. These nutrients are stored in different parts of the plant, such as the leaves, fruits, seeds, and roots, and can be harvested for human consumption. Animals also provide food for humans and other animals. Meat, dairy products, and eggs are some examples of animal-derived foods. Animals obtain their nutrients by consuming plants or other animals, and the nutrients get transferred up the food chain to other animals that feed on them.

Hence,   The food that animals and people eat comes from a variety of sources, including plants, animals, and other organisms.

Answer:

Placer mining

Explanation:

Placer mining can be less damaging to the environment than surface mines, as the sediment is returned to the water after the minerals have been extracted.

The mining that is likely the least harmful to the environment is the placer mining that is present in Option B, water is used in placer mining to separate mineral particles from soil.

Placer mining involves the extraction of minerals from riverbeds, streambeds, and other bodies of water, and this method involves the use of water to separate mineral particles from soil, while placer mining is generally considered to be less harmful to the environment compared to surface and subsurface mining, but it can still have negative impacts if not properly managed. For example, the use of mercury in the gold extraction process can lead to water pollution and harm to aquatic life.

Hence, the mining that is likely the least harmful to the environment is the placer mining that is present in Option B.

Explanation:

Answer:

The answer is "8 beta-oxidation cycles".

Explanation:

Please find the complete question in the attached file.

In this complete oxidation of active oleic acid 18:1(Δ9), 8 beta-oxidation cycles are required. Oleic acid is saturated fat, 9 to 10-carbohydrate fatty acid. Its double bonding is cis-focused. Its cycles for beta-oxidation required to oxidize an active oleic acid fully are 8.

It's initial two fatty acids are removed by oxidation in β - oxidation from the initial two carbon atoms. The recently formed carbon units are made up of creating temporary A molecules (acetyl- CoA). That cycle for oxidative begins with both the coffee grounds terminals of the fat lactone chain.

A) WHAT IS THE PROBLEM WITH HER PLAN?

Binary fission is one of the asexual process by which most bacteria reproduce, the binary fission brings about a doubling of the number in bacterial cells that are viable.

Generation time is that time that it will require for a cell population to divide and double, it is also known as doubling time. This Generation time varies among distinct organisms and also varies among culture conditions.

Take for instance,a fast growing bacterium that is under an ideal culture conditions has a doubling time of 20minutes and for the bacteria that is grown in a condition that is not so ideal,may have a doubling time of hours.

The major challenge/ problem with her plan is that as she takes the bacterial sample every 30minutes, and then hold the sample till the last sampling is done in the day,those bacterial cells that are collected in the initial intervals will then get divided and further gives a result that is false.

However,if those bacteria that are collected aren't stored in a culture environment that is standard,the bacterial cells may die off and thus will further bring about a false result.

2) CAN SHE DO ANYTHING TO IMPROVE THE ACCURACY OF HER RESULT?

Solution for rectifying the error in her plan;

She can go ahead and add 50-100 μl of formaldehyde to all the culture suspensions that she has and has taken every 30minutes.

As the formaldehyde will fix the bacterial cells,The optical density present in all those aliquots can then be retrieved/taken at the end of the day.

Looking at it alternatively, aliquot 1ml of the culture suspension at an interval of every 30 minutes,and then take the optical density that is OD at a wavelength of 600nm making use of spectrophotometer until the reason you get becomes static.

Answer

i think its C.

Answer:

The final volume is the sum of the initial volume and the volume of the object.

Explanation:

Since we know that the volume of the object is the difference between the final and the initial volume, let the volume of the object be ∆V, let the initial volume be V1 and let the final volume be V2.

From;

∆V= V2 - V1

V2= ∆V + V1

Bones are classified is by their shape are flat, long, short, and irregular are the classifications of bones based on their shape. Mrs. Morgan's humerus is a long bone, the occipital bone is flat, and vertebra is an irregular bone. Morgan's vertebrae is fractured.

Bone has a connective tissue which has been metabolically active and the main function of the bone has to provide mechanical as well  as structural support as well as perform movement, and protect important organs of the body.

The bone has been made up of the bone cells known as the osteocytes and extracellular matrix. The total number of bone of the human body contain has 206 bones including bones of spine, legs, arms, ribs, and skull.

Bones are made up of calcium and carbonate and they have bone marrow in which blood cells are produced. By nature bones came in category of living and they are active tissue .

There are several types of bones such as the flat bones, short bones, sesamoid bones, and long bones. The function of bone has to protect vital organs of the body.

Attachment, Penetration and Replication

Explanation:

A bacteriophage is a virus that attacks bacterial cells. The lytic and lysogenic cycles are two methods of viral replication. In the lytic cycle, the virions produced are released from the host cell whereas in the lysogenic cycle, viral nucleic material are incorporated into host nucleic material and are copied to daughter cells when the host cell reproduces. The common steps in both cycles are given below:

1  Attachment – in this step, the bacteriophage attaches itself to the surface of the host cell so as to insert its DNA into the host cell.

2. Penetration – the virus inserts its DNA into the host cell by penetrating the cell membrane of the host cell.

3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism.

The stages of replication is  Attachment, Penetration and Replication

Answer: The process is called EUTROPHICATION. The correct option is C.

Explanation:

Eutrophication is a type of environmental pollution where by there is an increase in nutrient salts of a water body which can lead to structural changes in the affected aquatic ecosystem. These changes includes:

--> Increase in production of algae: this effect causes algae blooms which makes the water murky, greenish and unpleasant for certain activities such as swimming.

--> Decrease in aquatic life: the presence of excessive growth of algae which are often degraded by microorganisms. When the rate of degradation of the algae by microorganisms is greater than that of oxygen regeneration a hypoxic state occurs which is harmful to aquatic life example fishes.
