what is the advantage of a cell being shaped like a sphere and one shaped like a cylinder?

Answers

Answer 1

Answer:

There are basically three types of cell shapes: coccus (spherical), bacillus (rod or cylindrical shaped), and spiral (twisted). Cell size is limited by a cell's surface area to volume ratio. The Shape of a cell determines the function of the cell.

Cells having spherical shapes are best and most advantageous because they have the smallest size that increases the surface-to-volume ratio. The cells with spherical shape experience greater frictional resistance.

Cells having a cylinder or rod-shaped helped the cell to concentrate molecules at specific cellular locales. Cylindrical cells are able to concentrate proteins at different locations in the cell.

how did cb van niel's studies with purple sulfur bacteria lead to his hypothesis that the oxygen released in photosynthesis comes from the water and not the carbon dioxide?

Answers

These studies were based on the observation that the oxygen released during photosynthesis by purple sulfur bacteria was isotopically identical to the oxygen found in water, rather than the oxygen found in carbon dioxide.

Van Niel's studies were based on the fact that photosynthesis is a process that converts light energy into chemical energy, which is used to produce organic compounds. During photosynthesis, purple sulfur bacteria take in carbon dioxide and water, and using light energy, they split the water molecules into oxygen and hydrogen. The hydrogen is then used to reduce the carbon dioxide to form organic compounds, such as glucose.

Based on his observations, Van Niel proposed that the oxygen released during photosynthesis comes from the water and not from the carbon dioxide. This hypothesis was later confirmed by other scientists, who showed that the oxygen produced during photosynthesis is actually derived from the water molecules, not from the carbon dioxide. This process is known as water-splitting and it is the first step in photosynthesis in which the water molecule is split into hydrogen and oxygen by the enzyme photosynthetic oxygen evolution complex.

Punnett squares can be used to predict the probability of: a) being exposed to a contagious disease and contracting it b) having an inherited disease or a genetically determined physical trait c) both of the above

Answers

Answer:

b) having an inherited disease or a genetically determined physical trait

Explanation:

The Punnett square is a simple diagram that can help determine which traits are the most probable in offspring depending on the genes of the parents. It only helps when looking at the probability of genetics or trying to understand how the characteristics of an offspring are linked to the characteristics of its parents.

Because of this, a Punnett square could not be used to predict the probability of being exposed to a disease or contracting it, but it could be used to determine the probability of having an inherited disease or a genetically determined physical trait.

A mitosis inhibitor is a medication that is designed to prevent mitosis in certain cells. Why would these be helpful in treatment of tumors?

Answers

"Mitosis inhibitors are used to stop cells from dividing and replicating. Tumors are made up of cells that have uncontrolled growth and division, so mitosis inhibitors can be helpful in the treatment of tumors because they can stop the cells in the tumor from dividing and growing. By preventing the tumor cells from replicating, the growth of the tumor can be slowed down or even stopped, which can be an important step in the treatment of cancer. Some examples of mitosis inhibitors include taxanes, vinca alkaloids, and paclitaxel, which are used in chemotherapy to treat a variety of cancers. However, it's worth noting that mitosis inhibitors can also affect healthy cells that divide rapidly, such as hair follicles and cells lining the gastrointestinal tract, which can cause side effects like hair loss and digestive problems."

which division of the nervous system includes the nerves that extend from the brain, the spinal cord, and sensory receptors?

Answers

The division of the nervous system that includes the nerves that extend from the brain, the spinal cord, and sensory receptors is the peripheral nervous system (PNS).

The PNS is one of the two main divisions of the nervous system, alongside the central nervous system (CNS). The PNS is composed of all the nerves and ganglia that lie outside of the brain and spinal cord, including sensory, motor, and autonomic nerves.

Sensory nerves transmit sensory information from the receptors in the body to the brain and spinal cord, while motor nerves transmit motor information from the brain and spinal cord to the muscles and glands. The autonomic nervous system (ANS) is a subdivision of the PNS that regulates involuntary body functions, such as heart rate, blood pressure, digestion, and breathing.

Overall, the PNS plays a crucial role in receiving and transmitting information between the body and the CNS, allowing for coordinated movement and sensory processing.

Answers

Part A: The bull's Darwinian fitness is probably (a.) >1

Part B: The other male seals' Darwinian fitnesses are probably average: (c.) <1

Part C: The average Darwinian fitness of the individuals in the entire population is probably (b.) =1

Part A: Darwinian fitness is defined as the contribution of an individual to the gene pool of the following generation relative to the average for the population, as a result of the selection pressures. An organism with a high fitness level is more likely to survive and reproduce than an organism with a lower fitness level. In the elephant seal population, the sexually dominant bull has the highest Darwinian fitness since it has a greater likelihood of passing on its genes.

Part B: Since other male seals do not get the opportunity to mate, their fitness levels are relatively low, which suggests that their Darwinian fitness level is below average.

Part C: The average Darwinian fitness level of the population is 1 in a stable population that neither grows nor shrinks. This suggests that the rate of the organism's population with a higher fitness level is similar to that of the population with a lower fitness level.

the folowing statements are true about fermentation: a. all of the above are true b. net two molecules of atp are produced c. takes place in prokaryotes and eukaryotes. d. does not require o2.

Answers

All of the above statements are true about fermentation. In fermentation, net two molecules of ATP are produced. This process takes place in both prokaryotes and eukaryotes. However, fermentation does not require oxygen.It is an anaerobic process.

Fermentation is a metabolic process that produces ATP through the breakdown of glucose. This process does not require oxygen and takes place in the absence of oxygen. In fermentation, glucose is converted into pyruvate, and then pyruvate is converted into ATP. The net production of two ATP molecules per glucose molecule is lower than that of aerobic respiration, but fermentation does not require oxygen, making it an important process in anaerobic conditions.

Fermentation is used by many organisms, including bacteria, yeast, and some plants. In bacteria, fermentation is used to produce lactic acid, which is then converted into ATP. In yeast, fermentation is used to produce ethanol and carbon dioxide. In plants, fermentation is used to produce lactic acid, ethanol, and carbon dioxide.

Fermentation is an important process in the food industry. It is used to produce bread, wine, beer, and cheese. It is also used to produce yogurt, sauerkraut, and other fermented foods.

Parenteral includes any routes other than the _____.

Answers

Parenteral includes any routes other than the gastrointestinal (GI) route. The choice of route depends on the medication being administered, and the desired outcome.

The GI route involves the administration of medications or nutrients through the mouth, and the drug or nutrient is then absorbed by the digestive system. Parenteral routes, on the other hand, involve administration of medications or nutrients through routes other than the GI tract, such as intravenous (IV), intramuscular (IM), subcutaneous (SC), intradermal (ID), intra-arterial, and intrathecal. Parenteral routes are often used when oral administration is not possible or effective, or when rapid drug delivery is necessary. Intravenous administration provides the most rapid onset of action, while other routes, such as intramuscular and subcutaneous, provide a slower onset of action.
