All Cells contain ribisomes and cytoplasm.

Cytoplasm- is used to help break down enzymes, it aids in membrane activity, it gives the cell its shape, and it helps keep organelles in their place.

Ribisomes- Help make proteins, and help convert DNA to RNA.

The first commercial application of genetic engineering was the use of bacteria to make insulin, a medicine needed by diabetics.
Murljashka [212]

Answer:

The question is incomplete, it lacks options. The options are:

A) It has made the demand for insulin decrease.

B) It has made the incidence of diabetes decrease.

C) It has made it easier for diabetics to inject themselves with insulin.

D) It has made insulin cheaper and more readily available.

The answer is D

Explanation:

Genetic engineering is a biotechnological procedure that involves the transfer of genes from one organism to another using biotechnology. In this case, bacteria cells are said to be genetically modified because their genetic content is tampered with and the genes that produces the insulin protein in humans is added into their genome. Hence, they transcribe and translate this gene to produce the protein-insulin.

Diabetic patients cannot produce this insulin in their system. Hence, the insulin produced from this genetically modified bacteria cells can be administered to diabetics via injection. This genetically modified way of producing insulin has proven to be a far better option to the previous practice of slaughtering cattles and pigs to obtain this protein because the GM method allows insulin to be produced in large amounts making it available and cheaper to diabetics.

You are a molecule of phosphorus. Choose a starting point in the process you would go through to move through the entire cycle.
noname [10]

Answer:

First I'd be found in rocks. Erosion would wash me into the soil. Then I'd be absorbed by plants, fungi or microorganisms so they can grow. Animals would get me by eating the plants or drinking the water that eroded the rock. The plants and animals die and I'm absorbed back into the soil.

Explanation:

Phosphorus Cycle Steps

The phosphorus cycle is a slow process, which involves five key steps.

Weathering

Since the main source of phosphorus is found in rocks, the first step of the phosphorus cycle involves the extraction of phosphorus from the rocks by weathering. Weather events, such as rain and other sources of erosion, result in phosphorus being washed into the soil.

Absorption by Plants and Animals

Once in the soil, plants, fungi, and microorganisms are able to absorb phosphorus and grow. In addition, phosphorus can also be washed into the local water systems. Plants can also directly absorb phosphorus from the water and grow. In addition to plants, animals also obtain phosphorus from drinking water and eating plants.

Return to the Environment via Decomposition

When plants and animals die, decomposition results in the return of phosphorus back to the environment via the water or soil.  

Plants and animals in these environments can then use this phosphorus, and step 2 of the cycle is repeated.

Human Impact on the Phosphorus Cycle

Humans have had a significant impact on the phosphorus cycle due to a variety of human activities, such as the use of fertilizer, the distribution of food products, and artificial eutrophication. Fertilizers containing phosphorus add to the phosphorus levels in the soil and are particularly detrimental when such products are washed into local aquatic ecosystems. When phosphorus is added to waters at a rate typically achieved by natural processes, it is referred to as natural eutrophication. A natural supply of phosphorus over time provides nutrients to the water and serves to increase the productivity of that particular ecosystem. However, when foods are shipped from farms to cities, the substantial levels of Phosphorus that is drained into the water systems is called artificial or anthropogenic eutrophication. When levels of phosphorus are too high, the overabundance of plant nutrients serves to drive the excessive growth of algae. However, these algae die or form algae blooms, which are toxic to the plants and animals in the ecosystem. Thus, human activities serve to harm aquatic ecosystems, whenever excess amounts of phosphorus are leached into the water.

umka2103 [35]
<span>Hemostasis is the process of the body that seals blood vessels that rupture. The process is basically starts with an injury, then vascular spasm, platelet plug formation and then coagulation. 

During blood clot formation, blood is transformed into solid gel at site of damage, where plasma fibrinogen is converted into loose fibrin molecules, which bind together to form mesh. Platelets and blood cells get trapped here by the fibrin strands, which produces a clot. This part of the clot formation is called coagulation.
