Some mammals help maintain their body temperature by sweating when their bodies rise in temperature. Which property of water is responsible for the ability of sweat, which is mostly water, to help lower body temperature? Water absorbs heat by breaking hydrogen bonds. Water changes in density when it changes from a gas to a liquid. Water's ability to dissolve solutes, such as salt Water's ability to form hydrogen bonds with skin cells
Answer:
Water absorbs heat by breaking hydrogen bonds.
Explanation:
Specific heat is the amount of heat that must be absorbed or lost for 1 gram of that substance to change its temperature by 1 degree. As someone works out, their body releases sweat to keep their body from overheating. Specific heat it mentions that hydrogen bonds between water molecules require heat to form and break, which is what happens when we sweat.

A researcher collected a single-celled organism from birdbath water and grew the organism in a laboratory. The researcher observed the organism reproducing by cell division, which resulted in identical offspring generations. This organism exhibits a form of
Answer: The organisms exhibit a form of Asexual reproduction.
Explanation:
This is a form of asexual reproduction because Asexual reproduction is a form of reproduction where a single celled organisms or muiticellular organisms produce or divide to produce offsprings that are genetically identical without fusion of gametes and exchange of genetic materials.
This type of reproduction includes binary fission( where an organism divides into two), fragmentation( where an organism divides into fragments), budding, spore formation e.t.c.
an ice cube has the following dimensions :
5.5cm - 8.0cm - 8.4cm
its mass is 340g.Calculate:
a-its volume
b-its density
Answer:
The correct answer would be :
1 volume = 369.6
2. density = 0.9199
Explanation:
Given :
dimensions : 5.5cm - 8.0cm - 8.4cm
Mass : 340 g
Formula :
volume = side * side * side
density = mass/ volume
Solution :
volume of ice cube would be
= 5.5cm * 8.0cm * 8.4cm
= 369.6 m³
density of ice cube would be
= 340/369.6
=0.9199
Thus, the correct answer would be
1 volume = 369.6
2. density = 0.9199
Analysis in which general conclusions are drawn from specific observations is called
a. deductive reasoning
b. inductive reasoning
c. reductive reasoning
d. productive reasoning
Answer: Option B
Inductive reasoning.
Explanation:
It is inductive reasoning because inductive reasoning is a type of reasoning in which general informations are made based on some specific observations or information even when the conclusion is not complete guaranteed to be true.
This means that you make a guess's or generalizations based on the information you have at hand.
For example; The left handed people the you know uses left hand in right and you now make the conclusion that all left handed people write with their left hand only.

b produce and manage movement
Explanation:
nerve cells are there to move muscles, send signals to glands, or register sensory stimuli.
the function of a nerve cell in a multicellular organism is to carry and transmit signals. Thus Option A is correct.
What is the function of nerve cell ?Nerve cells or neurons are the specialized cell for communication which is under the nervous system.
It is composed of cell body with nucleus, axon and dendrites.
Axon and dendrites are the long extension from cell body where as dendrites receive signal and conduct the signal to the cell body.
It involve in transmitting the information throughout the human body, by generating electrical signals called action potentials.
The nerve cell also helps the body in the smooth conduction of metabolic activities.
It involve in both the voluntary and involuntary movement of the body parts.
The communication between the central nervous system is established by the help of nerve cell and the body parts by enabling the smooth transmission of messages.
Thus Option A is correct.

Monosaccharides are the monomers and polysaccharides are the polymers of carbohydrates. Amino acids are monomers and polypeptides are the polymers of proteins. Nucleotides are the monomers of nucleic acid and polynucleotides are the polymers of nucleic acids. Fatty acids and glycerol are monomers and triglycerides are the polymers of lipids.
What are monomers and polymers?Lipids, Polysaccharides, Proteins and Polynucleotides are the four major groups of macromolecules that are found in the bodies of all living organisms. These are also called biomolecules.
Monomers are small molecules which are generally organic. These molecules combine with other similar monomers which form large molecules. These are polymers. All the monomers can form chemical bonds with at least two monomer molecules.
A class of synthetic substances that are composed of multiples of simpler units or monomers are called polymers. These are the chains of monomers which have a nonspecified number of monomeric units.
Therefore, monosaccharides are the monomers and polysaccharides are the polymers of carbohydrates. Amino acids are monomers and polypeptides are the polymers of proteins.

Summarise the differences between the nervous system and the endocrine system on the body’s coordination. Nervous System / Endocrine system How is the signal sent throughout the body? How quickly does the signal travel? What does the signal do to the target cells? How long does the effect of the signal last?
The nervous system signals the endocrine system to release
hormones in response to a stimulus.
The nervous system respond to stimulus through action potentials and neurotransmitters and they signals the endocrine system to secrete hormones.
The endocrine system is responsible for secreting hormones into the blood which is transported to the target cells. These hormones are responsible for metabolism , growth and response to stress. The hormones secreted provide feedback to the brain so as to affect neural processing.
