Staphylococcus aureus is a bacterium that causes a variety of human ailments including boils, sties, and infections. While this bacterium is commonly found on the skin, mouth and nose, it does not usually cause harm unless it enters the body through an open wound.

Answers

Answer:

True.

Explanation:

Staphylococcus aureus is a bacteria that can be in the skin, nose, mouth, under the armpits, or on skin folds, but that is harmless unless that it enters the body through a cut or open wound. Once inside the body, the bacteria can cause different types of infections. These infections can be small ones or big ones such as pneumonia, meningitis, or endocarditis. The bacteria spread from one person to another by skin to skin contact or by being in touch with contaminated surfaces. That is why we should avoid touching dirty places, and we should wash our hands periodically.

What is Trilobite fossil?

Arthropods called trilobites are extinct. Rarely is a full fossil recovered; most often, only the skeleton occurs. A flexible, jointed thorax separated the head (cephalon) and tail (pygidium), which covered the upper part of the body.

Trilobite fossils are an essential part of Unit 4's pretest, as they provide valuable information about the history and evolution of life on Earth. When studying these ancient creatures, you'll be able to understand their anatomy, behavior, and the environments they lived in millions of years ago.

By examining trilobite fossils, you'll gain important insights into the geological time scale, the process of fossilization, and the significance of paleontology in scientific research.

Therefore, the correct option is B.

Watersheds may be contaminated by fertilizers and other pollutants. When these substances enter a waterway, they can cause algal blooms, which are rapid overgrowths of algae. When the algae die, the decay uses up a large portion of dissolved oxygen. Declining oxygen levels can then cause large die-offs of animals in the waterway. What will an algal bloom in a watershed most likely cause?

B)A decrease in the watersheds ecosystem diversity, which would improve its ability to supply large volumes of water.

C)An increase in the watersheds genetic diversity, which would reduce its ability to supply clean and safe drinking water.

D)An increase in the watersheds species diversity, which would improve its ability to supply large volumes of wate

Answer:

)A decrease in the watershed’s biodiversity, which will reduce its ability to supply clean and safe drinking water.

Explanation:

This sequnces of events is called  Eutrophication. It is the process of washing of  nutrients salts e.g., (NPK) into aquatic bodies which leads to change in the  ecosystem structure of the  aquatic bodies with the boom in algae growth, and drop in O2.

The cut in oxygen availability  in the aquatic bodies , leads to death of the fauna and flora.Theses are the varieties of life in this habitat.(biodiversity).

With the an increase in the death of these inhabitants(flora and fauna)couple with the activities of the (decomposers) the water bodies becomes dirty and unfit for drinking.

Besides as the pathways of the  watershield  ecosystem  as it filters the these polluted  water may be blocked by the dead organic matter from the flora and fauna. Thus A is the best.  

Cancer cells are different because they don't enter the G - 0 phase and they are likely to do which of the following Your answer: a)fail to complete the S phase b) mutate during G1 phase c) repeat the cell cycle continuously d) die after completing mitosis

Answers

Answer:

c) repeat the cell cycle continuously

Explanation:

Cell division is a normal phenomenon for all cells as this is the way the cell reproduces and gets repaired in living organisms. However, some cells, due to mutation, keeps dividing and proliferating to form tumours. These cells are called CANCER cells. A normal cell undergoes cellular repair at certain checkpoints of the cell cycle. The checkpoints are necessary to determine a faulty cell and stop its division.

However, cancerous cells do not undergo any repair, which is why they do not enter the G0 phase as mentioned in the question. They keep on dividing out of control without death by repeating the cell cycle continuously.

Explain the transcription and translation of fur color gene.

Answers

Answer:

Transcription of the fur colour gene involves the conversion of the gene that codes for the fur colour in the deoxyribonucleic acid of the animal to an ribonucleic acid template. While in translation, the ribonucleic acid template is converted to the required aminoacids which are linked up to form the protein that is expressed when the fur of the animal is to be determined.

Explanation:

In the process of transcription, the gene coding for fur colour in the animal found in in the deoxyribonucleic acid which houses all the genetic information of the animal is read in the ribonucleic acid format with adenine bases replaced with uracil instead of thymine. This format is then translated by the messenger ribonucleic acid per codon ( made up of 3 bases) into the protein responsible for fur colour until the stop codon terminates the transcription process. The polypeptide produced is then released and ready for expression.

A species of bacteria is found deep within the Earth's crust. Which process will the bacteria use to obtain energy? A. Cellular Respiration B. Photosynthesis C. Lactic Acid Fermentation D. Alcoholic Fermentation

Answers

Answer:

CELLULAR RESPIRATION

Explanation:

The process that the bacteria will use to obtain energy deep in the Earth's crust by cellular respiration. The correct option is A.

What is cellular respiration?

Bacteria use both aerobic and anaerobic cellular respiration. There are three major steps in aerobic cellular respiration: glycolysis and the citric acid cycle in the cytoplasm, and the electron transport chain in the plasma membrane.

The process of respiration in bacteria is carried out by mesosomes. Mesosomes are rolled up invaginations in bacteria's cell membrane.

Their purpose is to increase the required surface area for respiration. They are respiratory activity sites because they contain respiratory enzymes.

The process by which bacteria will obtain energy deep within the Earth's crust through cellular respiration.
