Answer:
This question is incomplete
Explanation:
This question is incomplete, however the question seeks to test the students ability to identify a dextran. The question already gives a brief description of a dextran hence the attachment provides a visual representation of what has been described in the question.
Dextrans are polysaccharides made up of individual glucose units (monomers) that are joined together by α(1 → 6) glycosidic bonds (as seen in the second diagram of the attachment); i.e the C-1 (illustrated as α-1 in the attachment) of one glucose unit is linked to the C-6 (illustrated as α-6 in the attachment) of another glucose unit by glycosidic bond. These dextran polymers are also characterized by branches from α(1 → 3) [as seen in the second diagram of the attachment]; i.e the C-1 (illustrated as α-1 in the attachment) of the branch glucose molecule is attached to the C-3 (illustrated as α-3 in the attachment) of a glucose unit in the polymer chain of the dextran.

The scientist Konstantin Mereschkowsky knew in the early 1900s that plants make their own food by using sunlight. He also saw tiny parts in plants called chloroplasts that do not appear in any animals. He hypothesized that chloroplasts are what help plants make food. After many more observations of all types of plants and animals, scientists are convinced today that chloroplasts make food for plants.

Choose 1 answer:
(Choice A)
A
Cell membrane
(Choice B)
B
Ribosome
(Choice C)
C
Cytosol
(Choice D)
D
Mitochondria
Answer:
I think its A
Explanation:
Since nucleoli are the locations where ribosome synthesis occurs, this toxin would stop ribosome synthesis, and a cell without ribosomes would be unable to carry out protein synthesis, hence option B is correct.
What is the synthesis of proteins in a cell?As ribosomes are the location of translation, the process by which an mRNA transcript is translated into a polypeptide chain.
The smooth endoplasmic reticulum (ER) is in charge of the detoxification of a variety of organic pollutants. A ribosome is an intercellular structure consisting of both RNA and protein, and it is the location of protein synthesis in the cell.
The smooth ER transforms organic compounds into water and other soluble products to enable excretion.
Therefore, the messenger RNA (mRNA) sequence is read by the ribosome, which then converts the genetic code into a predetermined string of amino acids, to carry out protein synthesis, hence option B is correct.

The right eye and right lung are
A. ipsilateral
B. bilateral
O C. contralateral
D. proximal
The right eye and right lung are ipsilateral.
The term ipsilateral is used in anatomy, it refers to the structure or organ that is located on the same side of the body.
Contrary to the contralateral term that indicates that a structure or organ is on the opposite side of the body.
Anatomy uses many geometric elements to define the location of all its parts. Thus, it uses planes, lines and regions, which can in turn be subdivided.
If we consider the right eye as a reference, the right lung is considered ipsilateral because it is on the same side.
Therefore, we can conclude that ipsilateral is part of the terms in anatomy, which are used for the location of structures and organs and are based on anatomical position, in the case of the right eye and right lung are ipsilateral they are found in the same side of the body.

Hope this helps :)
A drone is a type of unmanned aerial vehicle (UAV), which is an aircraft without a human pilot, crew, or passengers. Unmanned aerial vehicles (UAVs) are a part of unmanned aircraft systems (UAS), which also feature the addition of a controller on the ground and a communications network with the UAV.
What are the different types of UAVs?Fixed-wing drones are utilized for long-distance flights since they often have longer flight periods, but they also need a place to take off and land. Rotary drones, on the other hand, are utilized when greater mobility is necessary.
The two primary categories of UAS are fixed-wing and multirotor. Every type differs from the others in terms of its special traits, applications, and drawbacks.
Therefore, UAVs with fixed wings and rotating wings are the two basic types used for remote sensing applications.

How do cells regulate the passage of materials across their membranes in order to maintain
homeostasis?
Cells maintain homeostasis with the cell membrane. The cell membrane regulates what enters and exits the cell.
What is the function of cell membrane?The cell membrane help to maintaining homeostasis by regulating the flow of substances through it and by recognizing potentially harmful agents to the cell. Cellular membrane has been constituted by the lipidic bilayer, whose characteristics allow it to behave as a semi-permeable membrane to the passage of substances.
The selective permeability of the membrane makes it possible to regulate the passage of water, molecules and ions through it into the cell and from there into the extracellular space, a characteristic that allows the maintenance of homeostasis.
The cell surface can identify foreign and potentially harmful agents, which can affect the internal balance, preventing in most cases their passage into the cell.
Therefore, Cells maintain homeostasis with the cell membrane. The cell membrane regulates what enters and exits the cell.

Rabies Virus: People often associate rabies with dogs. Why is this incomplete
Answer:
Rabies is a disease that can be found in all mammals, and cannot be found in reptiles, birds, and amphibians. This disease causes a series of symptoms ranging from headaches, nausea, hyperactivity, confusion, anxiety, and the infamous excess saliva, which we commonly think of when we imagine a rabid animal. Rabies is also known as hydrophobia due to the patient's fear of water, which is one of the factors in the list of many accounting for death. Any mammal can get it, but wild animals are more commonly diagnosed with the disease. Foxes, raccoons, bats, skunks, cats, cattle, and dogs are all the most commonly reported, but the list carries on with any mammals. The common misconceptions are that bats and dogs almost always carry, but only 6% of bats and 9% of dogs have it. However, they are still the most common carriers. The least common carriers of the disease are often found to be small mammals, like squirrels and chipmunks.

Cell membranes are a border between the aqueous
environment outside the cell and the aqueous
environment of the cytoplasm inside the cell. Cell
membranes are in part made of phospholipid polymers.
Based on the properties of the monomers that make up the phospholipid polymer, which of the following best predicts how the two phospholipids are positioned in the cell membrane?
A) The hydrophilic heads will face outward toward the cell's exterior and inward toward the cell's interior. The fatty acids will be tail-to-tail in the center of the membrane.
B) The glycerol region in the fatty acid will bend toward the interior of the cell. The choline will bend toward the exterior of the cell.
C) The hydrophobic heads will bind with other
hydrophobic heads and turn inward to the center of
the membrane. The fatty acids will randomly move, giving the membrane fluidity.
D) One choline will turn inward toward other choline in the bilayer. The fatty acids will be attracted to the choline and form the interior of the membrane.
Answer:
I think it’s C because the tails are inside the lipid bilayer and the choline which looks like the hydrophilic heads are the exterior
The hydrophobic tails of the phospholipid are in the interior with the hydrophilic heads facing the aqueous envrionment internally and externally in the cell membrane.
What is the cell membrane?The cell membrane is a phospholipid bilayer which serves to separate and protect the internal cell contents from the external envrionment.
The cell membrane membrane is arranged such that the hydrophobic tails of the phospholipid are in the interior with the hydrophilic heads facing the aqueous envrionment internally and externally.
Therefore, the hydrophilic heads will face outward toward the cell's exterior and inward toward the cell's interior while the fatty acids will be tail-to-tail in the center of the membrane.
