Cellular organelles have different structures. Mitochondria, for example, possess highly folded inner membranes in addition to their outer membranes. Vacuoles, on the other hand, are only surrounded by a single-layer membrane; they do not have an inner membrane.
Why do cellular organelles have different structures?
A.
Organelles that are less important to the cell have less sophisticated structures.
B.
All of the organelles in a particular organism are identical, but organelles in different organisms are unique.
C.
The structure of a cellular organelle mimics the appearance of the organism.
D.
The structures of cellular organelles are related to their functions.
Answer:
D
Explanation:
Different oganelles do their own function.
The structures of organelles differ because the structures of organelles are related to their functions.
What are the functions of cell organelles?An organelle is a subcellular structure that has one or more specific functions in a cell, such as an organelle in the body. The most important cell organelles are the nuclei, which store genetic information.
Organelles are small structures in the cytoplasm that perform functions necessary to maintain homeostasis in the cell. They are involved in many processes, such as energy production, the formation of proteins and secretions, the destruction of toxins, and responding to external signals.
Examples of membrane-bound organelles include the nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes, and vacuoles.

will you be able to synthesize both strand of the dna helix in a continuous manner?
Answer:
No.
Explanation:
There are two strands in DNA -i)Leading strand
ii)lagging strand.
Replication of the leading DNA strand is continuous, while replication along the lagging strand is discontinuous. After a short length of the DNA has been unwound, synthesis must proceed in the 5' to 3' direction; that is, in the direction opposite that of the unwinding.
No, we will not be able to synthesize both strand of the dna helix in a continuous manner because the lagging strand synthesize in a discontinuous manner.
What is the process of DNA synthesize?The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the most crucial component of biological inheritance.
Continuous DNA synthesis takes place on the leading strand. As the helix unwinds, DNA synthesis on the lagging strand restarts numerous times, resulting in numerous brief pieces known as "Okazaki fragments," which are then joined by DNA ligase to form a single DNA molecule.

most of the energy that your brain uses comes from
Answer:
Glucose
Explanation:
The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.
Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.
Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.
The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.
Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.

S. aureus is gram positive. What differences in strains might account for differences in phage susceptibilities?
S. aureus is indeed gram-positive but within the bacteria classed as gram-positive, there are differences that might predispose them to infection by phages.
S. aureus as an organism usually adapts to their environment through mutations on their membranes which can be proteins e.g. surface proteins, or receptor molecules e.g. sugar receptors.
In preventing invasion by phages, mutations are gained that prevents attachment to the bacteria cell surface. This effectively prevents the binding of the phage to the bacteria thus preventing infection.
It is also worthy to note that the differences in bacteria strain could range from a few nucleotides to large variations in chromosomes and thus can aid in identifying specific strains that might have beneficial factors in the context of disease prevention.
