A molecule that has regions of partial positive and partial negative charge
A) polar
B) hydrogen bond
C) surface tension
D) universal solvent
E) adhesion
Answer:
A) polar
Explanation:
Polar molecules contains partial positive and partial negative charge as in all polar molecules two atoms have unequal sharing electron. Due to unequal sharing of electrons, one atom that attracts valence electrons strongly gains positive charge and other gain negative charge.
For example water, water is a polar molecule having partial negative and partial positive charge because the oxygen atom in water attracts electrons more strongly than the hydrogen atoms.
Hence, the correct answer is "A) polar".

One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don't soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.

Can a single cell be a living organism?
1.yes
2.no
A single-celled organism can be a living organism. In the single-celled organisms, all the functions are performed by a single cell. Thus, the given statement is true.
What are the single-celled organisms?A unicellular organism is also known as a single-celled organism. The unicellular organism is an organism which consists of a single cell only, unlike the multicellular organism which consists of multiple cells and tissues. These organisms fall into two major categories, which are the prokaryotic organisms and the eukaryotic organisms.
The two categories of organisms are classified on the basis of the membrane-bound organelles and a well-defined nucleus present in the cell. Some examples of the single-celled organisms include Escherichia coli, Diatoms, Protozoa, Protista, Pneumococci, and Dinoflagellates.

Which list correctly identifies characteristics that protists share with animals?
A. Motile, Reproduce sexually, Photosynthetic
B. Motile, Multicellular, Photosynthetic
C. Motile, Eukaryotic, Reproduce Sexually
D. Motile, Prokaryotic, Multicellular
Answer:
C. Motile, Eukaryotic, Reproduce Sexually
Explanation:
I just took the Test
The list that depicts the characteristics animals and protist share is: C. Motile, Eukaryotic, Reproduce Sexually.
Protist and animals are classified as eukaryotic organisms, this is because they have a well-defined nucleus. Thus, both are eukaryotic.
Virtually all protists are capable of moving with the aid of structures such as pseudopodium, flagella or cilia. Also, animals possess well developed structures and organs for movement. Hence, protist and animals are motile.
Animals reproduce sexually through the fusion of male and female gametes to produce their offspring. Also, some protist such as Plasmodium reproduce sexually.
A photo collage showing the image of some protist is provided in the attachment below.
Therefore, the list that correctly describes the characteristics shared by protist and animals is: C. Motile, Eukaryotic, Reproduce Sexually.

Which health factor is an individual unable to change?
A-nutrition
B-environment
C-inherited genes
D-cholesterol levels
Answer:
C-inherited genes
Explanation:
The health factor that an individual is unable to change is inherited genes, which is in Option C, as inherited genes are passed down from parents to their offspring and can influence an individual's health.
What are inherited genes?Inherited genes are a fundamental aspect of an individual's biology that they are born with and cannot change. These genes provide the blueprint for the development and functioning of various systems in the body, including the immune system, cardiovascular system, and nervous system. Some genetic traits can increase an individual's risk of developing certain diseases or conditions, while others may protect against certain health problems. While individuals cannot change their inherited genes, they can take steps to manage their health based on their genetic risk factors.
Hence, a health factor that an individual is unable to change is inherited genes, which is in Option C.

What percentage of energy is lost as you move up trophic levels?
Answer: 10 percent
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

What happens when a cell gets too large?
Answer:
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.

Regulation of body temperature in humans is most closely associated with the
A) production of gametes
B) evaporation of sweat
C) absorption of carbon dioxide
D) production of hydrolytic enzymes
Answer:
b
Explanation:
Regulation of body temperature in humans is most closely associated with the evaporation of sweat that is present in option B, as the higher the body temperature, the more sweat is needed to maintain homeostasis.
What is the need for homeostasis in the body?The body maintains a particular internal temperature irrespective of changes in the external environment, and this is possible because of the homeostasis in the body, which is important because many of the body's processes are temperature and pH sensitive, such as the enzymatic function, the alkalinity of blood, etc.
Hence, regulation of body temperature in humans is most closely associated with the evaporation of sweat that is present in option B, as the higher the body temperature, the more sweat is needed to maintain homeostasis.

what is a cell organelle that has the same function as the urinary bladder?
The cell organelle that has the same function as the urinary bladder is the lysosome.
What are lysosomes?This is a spherical sac-shaped cell organelle surrounded by a single membrane. (Unlike chloroplasts and mitochondrial membranes, which have two membranes.)
It contains hydrolytic digestive enzymes, which split molecules by the addition of water molecules. Autolysis/autophagy, which is the automatic discharge of digestive enzymes in a contained cell that destroys the entire cell, separates the digestive enzymes from other cell organelles.
Plant and animal cells both include lysosomes. The lysosome degrades or eliminates worn-out or damaged organelles. Waste management is something that serves the same purpose.
Therefore, the lysosome is a cell organelle that performs the same job as the urine bladder.

List at least two variables that might influence the rate of cellular respiration.
Answer:
Answer below !
Explanation:

2) Temperature
3) Glucose Availability
Hope I helped and have a great day ∩^·ω·^∩ !
Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises.
What variable that influence the rate of cellular respiration?Since all living cells require both glucose and oxygen to operate properly, variations in the concentration of glucose have an effect on the rate of cellular respiration. If a cell's glucose level is low, it cannot produce energy in the form of ATP molecules.
High oxygen concentrations enable cells to perform aerobic respiration, which uses oxygen to build ATP and generates more ATP than anaerobic respiration, which occurs when oxygen is not present.
As a result, increased cellular respiration is often associated with warmer temperatures.
Therefore, Oxygen Concentration, Temperature, Glucose Availability
