Answer:

Vacuoles in animal cells do NOT help the cell take its shape, however, in plant cells, vacuoles are larger, and DO affect the shape of the cell.

The function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials.

Vacuoles are cell organelles found in both plants and animals, in plants, vacuoles are large, fluid-filled structures that occupy a large portion of the cell, and they perform several important functions, including storing water and helping to maintain the shape of the cell, while in animals, vacuoles are smaller and less in number than in plants, as they have a variety of functions, like storing waste materials, etc.

Hence, the function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials

Also the term "secondary sexual characters" typically refers to physical characteristics that distinguish males from females in sexually reproducing species, such as antlers on male deer or breasts on human females. These characteristics are not related to the reproductive organs themselves (the primary sexual characteristics) and typically develop during adolescence as a result of hormonal changes in the body.

Explanation:

when it's fully charged it's a ATP and when it's runs down it's ADP

and there are times when the cells need more energy and splits off another phosphate so it goes from ADP adenoside di-phosphate, to AMP, adenosine mono-phosphate

Answer:

the material or protoplasm within a living cell, excluding the nucleus.

Explanation:

Answer:

An unbalanced diet and lack of exercise can lead to high levels of bad cholesterol (LDL) and triglycerides in the blood, which can contribute to the formation of an atheroma. An atheroma is a fatty deposit that forms within the walls of arteries.

When levels of LDL and triglycerides are high, they can accumulate in the walls of blood vessels, causing plaque buildup. This buildup can lead to atherosclerosis, which is the hardening and narrowing of arteries over time. As the plaque buildup increases, the diameter of the artery becomes smaller, and the blood flow to vital organs, like the heart and brain, is reduced.

Over time, the atheroma can grow and become unstable. When it ruptures, blood clots can form on the surface, further blocking blood flow and possibly leading to a heart attack or stroke.

A balanced diet and regular physical activity can help maintain healthy blood cholesterol and triglyceride levels, reducing the risk of atheroma formation. A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats can help lower bad cholesterol levels. Exercise helps increase good cholesterol (HDL) levels, which helps remove excess bad cholesterol from the bloodstream.

The statements that are hypotheses are: (1)Glucose may cause an increase in bacterial growth; (4) Increased glucose may lead to capsule formation in bacteria.

The statements that are observations are: (2) The bacterial colonies grown without glucose don’t have capsules around their cells; (3) Bacterial growth in the glucose environment increased rapidly and then stopped after some time.

Glucose is the main food component of microorganism as well as many large organisms including humans. It is the source of instant energy. Glucose is broken down inside the living body to yield energy in the form of ATP.

Capsule is the layer present outside of the cell envelope and is made up of carbohydrates. The main role of capsules is to protect the bacterial cell from phagocytosis or death by the immune cells of the host body.

During puberty, hormones play essencial roles in the body and processes of growing up. If during that age a girl`s body is unable to produce estrogen or progesterone, it means that a few events won`t happen. One of them is the menstrual cycle. Both estrogen and progesteron work together for the maturation of oocytes, and in the lack of estrogen and progesteron, the girl wouldn`t be fertile, and besides that, the changes that the endometrium has to go through during the period wouldn`t occur. Also, changes in the body such as breast growth and hip enlargement will also be hampered, because they are associated to those hormones as well. In the case of a boy`s body being unable to produce testosterone, the sperm production would be affected, and the boy would be infertile. Other processes like hair and genital growth, muscle gain and voice deepening would be negatively affected.

Explanation:

A compound light microscope uses two lenses at the same time to view objects-the objective lens, which gathers light and magnifies the image of the object, and the ocular lens, which one looks through and which further magnifies the image. ... it also allows light to pass to the ocular lens.

Staphylococcus aureus was identified as an unknown by performing various laboratory tests. This process is called bacterial identification.

There are numerous methods for bacterial identification, but all of them aim to distinguish between different species of bacteria. These methods may be based on phenotypic, genotypic, or proteomic characteristics. In the case of Staphylococcus aureus, the tests were focused on its phenotypic characteristics.

Phenotypic characterization includes the use of microscopy, culture characteristics, and biochemical tests to identify the bacterial species. Gram staining is the first step in identifying an unknown bacterial species, which is used to categorize bacteria into Gram-positive or Gram-negative. Staphylococcus aureus is Gram-positive cocci that appear in clusters. It is differentiated from other cocci by performing additional biochemical tests such as catalase, coagulase, mannitol fermentation, and DNA se tests.

Catalase test is done to differentiate between staphylococci and streptococci, which are both Gram-positive cocci but have different catalase activity.
