What are the three properties of water that are unique to the conditions found on earth
Need help ASAP thank you
Answer:
It boils at 100 degree celsius
Cohesion: Hydrogen bonds holds water molecules together
It has high specific heat capacity
It boils at 100 degrees Celsius. Cohesion: Water molecules are held together by hydrogen bonds. It can withstand a lot of heat.
What makes water to unique?Water's chemistry and physics make it so special. Understanding water's most fundamental chemical characteristics is the first step in exploring its special characteristics.
Polarity is one of the special characteristics of water because it is composed of polar molecules. Each water molecule has one oxygen atom and two hydrogen atoms (H2O). Hydrogen bonds, which connect water molecules to one another.
Therefore, because water contains hydrogen bonds, the molecules are very cohesive and adhere to one another tightly. It is crucial to note that water has substantially stronger cohesiveness than the majority of other liquids.

Dextrans are polysaccharides produced by some bacteria. They are polymers of α-D-glucose linked by α(1 → 6) glycosidic bonds, with frequent α(1 → 3) branching. Choose the correct portion of a dextran, including one branch point. Dextrans are polysaccharides produced by some bacteria. They are polymers of -D-glucose linked by (1 → 6) glycosidic bonds, with frequent (1 → 3) branching. Choose the correct portion of a dextran, including one branch point.
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.
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.

to prove that all medical conditions are related to specific genes
to develop organisms that have identical genomes
Answer:
B. to understand the function of genes that are effected by disease
Explanation:
i took the test
Answer:
B is the correct answer
Explanation:
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.

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.

Answer: There are two main types of UAVs used for remote sensing applications: fixed-wing and rotary wing.
Please mark me as Brainliest
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.
