Answer:
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. The stream of water bends due to the polarity of water molecules.
All the properties of water are related to one another by the polar nature that is caused by the partial electronegativity difference of the hydrogen and oxygen molecules of water molecules.
A water molecule has uneven distribution of charges between different atoms of the different molecules. All types of properties of water due to attractions between these polar molecules.
in water molecules slightly negative atoms of one molecule are attracted to the slightly positive atoms of other moleculesthe attraction forms hydrogen bonding, weak bonds between a hydrogen atom and another atomProperties of water due to polarity and hydrogen bonds:
surface tension - a measure of the force necessary to stretch or break the surface of a liquidcapillary action - the tendency of water to rise in a thin tubecohesion - water attracted to other water moleculesadhesion - Water attracted to other materialshigh specific heat - the amount of the heat that must be absorbed or lost for one gram of the substance to change its temperature by 1°Cexpansion upon freezing - ice is less dense than and on freezing it expands its structure and forms a cage-like structure.Learn more about the properties of water:

Cells are made of organelles, specialized structures that each perform specific functions that help the cell maintain homeostasis. This is much like the body systems work together to help the body maintain homeostasis. Consider the function of the nervous system. Which organelle is most similar in function?
Answer:
Organelles serve specific functions to keep a cell alive.
Explanation:
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.

Which type of bonds form between the oxygen and hydrogen atoms of within a water
molecule
Answer:
covalent bonds
Explanation:
Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other. Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge. The area around the oxygen is somewhat negative compared to the opposite, hydrogen-containing end of the molecule, which is slightly positive.

A lipid is a phospholipid, a major structural component of all cell membranes. It is composed of a glycerol molecule, two fatty acids
The type of biomolecule that is made up of fatty acids is Lipids and thus, option C is the correct answer.
Nucleic acids, Lipids, Proteins, and Carbohydrates, are some of the significant biomolecules. The characteristics of lipids are listed as follows:
The organic molecule that is specifically related to fatty acids and can be able to dissolve only in organic solvents and not in water are called lipids. The lipid molecule is composed of 1 molecule of glycerol and 3 molecules of fatty acids that are linked to one another. Oils, waxes, fats are some examples of lipid molecules.Thus, we can conclude that lipids are the type of biomolecules which is made up of fatty acids.

why does the central part of a red blood cell appear paler than the outer part when viewed under a light microscope
Answer: The central pale area of each red blood cell is due to the concavity of the disc.
Explanation:
The absence of a nucleus and light effect makes the central part of a red blood cell appear paler
The red blood cells ( RBC )does not have a nuclei like every other cells contained in the body. therefore when viewed under a light microscope the outside of the red blood cell will appear brighter ( pink ) while the center of the red blood cell will appear pale ( whitish ). also the the light intensity from the light microscope contributes to the pale nature of the central part of the red blood cell.

Many populations exhibit the following growth curve.
Which statement(s) below accurately are describing the growth as shown on the graph. NOTE: There is MORE THAN ONE correct answer. Choose ALL that apply.
Select 3 correct answer(s)
Question 5 options:
Phase B of the graph is showing a population that has reached its carrying capacity.
When both phases of the graph are looked at together, it shows logistical growth of a population after growing exponentially and reaching its carrying capacity .
Phase B of the graph is showing exponential growth only.
The entire graph shows two organisms competing for space.
Phase A of the graph is showing exponential growth only.
Many populations exhibit the following growth curve.. Here option 1, 2, 3 are correct which describe the growth. Phase B of the graph is showing a population that has reached its carrying capacity.
What is carrying capacity ?
The carrying capacity of the individual is the maximum number of population size of the species in a sustainable environment which is indefinitely reach up to the limit of no further growth.
Carrying refers to support and Capacity means it is the ability of an organism to reproduce the maximum output, when population reaches the limit of carrying capacity then the mortality will be greater than natality.
The importance of Carrying capacity is mainly focused on the concept of sustainability, imbalance in the environmental and Global warming which are the causative agent, eradication of poverty and practices are also increase the importance of carrying capacity.
