What are the drops of water that form on cool surfaces during the night called?
A. Snow
B. Dew
C. Steam
D. Rain
Answer:
The correct option is B
Explanation:
Dew is the water droplets found on objects outside of an enclosed/covered area in the morning. Dew occurs as a result of condensation of moisture in the cold atmosphere (at night) which is converted to liquid when it touches objects of higher thermal energy; converting the water in the moist air into water droplets known.

Pls answer now I am giving 40 points
Answer
:proteins
The four classes of macromolecules are carbohydrates, proteins, nucleic acids, and lipids. These biomolecules can also be referred to as polymers. In turn, we will discuss how these four classes of macromolecules are synthesized in the cell from their constituent building blocks or monomers.
Explanation:
Antibody Classes. Antibodies can be divided into five classes—IgM, IgG, IgA, IgD, IgE—based on their physiochemical, structural, and immunological properties. IgGs, which make up about 80 percent of all antibodies, have heavy chains that consist of one variable domain and three identical constant domains.
Answer:
Antibodies are proteins. An antibody (Ab), also known as an immunoglobulin (Ig), is a large Y-shape protein produced by plasma cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses
Explanation:

What is the purpose of cellular respiration
Answer:
Cells do cellular respiration to extract energy from the bonds of glucose and other food molecules. Cells can store the extracted energy in the form of ATP (adenosine triphosphate)
Explanation:
Answer:
The purpose of cellular respiration is to transfer energy from glucose to ATP. This is important because we need energy, and we use it to move.
During facilitated diffusion - it is still passive but needs help of proteins to help pass.

What is the criteria used to classify mammals into groups?
based on the type of food they eat
based on their appendages used for movement
based on how their embryos develop
based on their type of hair
Answer:
based on how their embryos develop
Explanation:
Mammals are further classified into three types: placental, marsupial, and monotreme.
Also, I just took the quiz and I got it right, mate :)
The criteria used to classify mammals into groups is the presence of hairs.
Mammals:
They are the animals who have mammary gland mean the mother feeds the milk to their newborn.
One unique characteristics of the mammal is that they have have hair in at least one stage of their development.
No other animals like reptiles or birds have true hairs.

A human liver cell has a different size and shape from a human muscle cell. What is the best explanation for these differences?
A. The cells perform different functions.
OB. One of the cells is used to reproduce more cells while the other is not.
OC. One type of cell develops into the other type of cell.
OD. One of the cells must have come from another species.
Answer:
A
Explanation:
A human liver cell would have a different size and shape from a human muscle cell because they perform different functions in the body.
The shape a cell would assume and its size depends on the function the cell performs. The functions of the liver in the body of humans differ greatly from the functions of muscles. While the former helps in detoxification, deamination, digestion, etc., the latter helps in support, movement, etc.
The correct option is A.
A human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.
CELL:
Cell is the basic and fundamental unit of life. It is the simplest level of organization of an organism. Cells contain organelles that help them perform specific functions. Organs are made up of numerous cells. Similar cells perform similar functions while dissimilar cells perform dissimilar functions. Therefore, a human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.Learn more at: https://brainly.com/question/22663686?referrer=searchResults
Please answer quickly!! Timed test! Which term is correctly paired with its role in the body? A) Insulin – a sugar that regulates blood glycogen levels B) ADP – a molecule that releases energy when it forms ATP C) Glycogen – a hormone found in blood that regulates blood glucose levels D) Glucose – a sugar found in blood that can be broken down to produce ATP
Answer:
The correct answer is - D) Glucose – a sugar found in blood that can be broken down to produce ATP
Explanation:
Insulin is a hormone produced by the beta cells of pancrease that takes up the glucose from the bloodstram and make gucose available to the cells of the body to produce energy by the process of cellular respiartion. Glucose is breaken down to its smaller units and produced high amount of energy in the form of ATP. Glycogen is form of sugar that is stores in the muscle and othe cell for the energy in abscence or low glucose level in blood stream. ADP is a molecule know as adesnosine pyrophosphate or diphosphate which is play role in flow of energy. ADP molecules requires energy to form ATP molecule and when ATP splits into ADP and Pi releases high amount of energy.

Can someone help me out with this? In pea plants, the allele for green seeds (G) is dominant over the allele for yellow seeds (g). • Parent 1: homo-zygous for green seeds • Parent 2: homo-zygous for yellow seeds. • What are the gametes each parent plant will produce? Parent 1: Parent 2:
Answer:
Parent 1: G gametes
Parent 2: g gametes
Explanation:
This question involves a single gene coding for seed color in pea plants. The allele for green seeds (G) is dominant over the allele for yellow seeds (g). This means that a plant that is heterozygous (Gg) will possess green seeds.
If two parents are about to cross in such a way that Parent 1 is homo-zygous for green seeds i.e. GG, while Parent 2 is homo-zygous for yellow seeds i.e. gg.
- Parent 1 (GG) will produce only "G" gametes
- Parent 2 (gg) will produce only "g" gametes
Which refers to the sum of all the forces that act upon an object?
A. net force
B. absolute force
C. balanced force
D. positive force
Answer:
Net force
Explanation:
Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
Answer:
net force
Explanation:
Fill in the blank: When you paddle a boat in the water. the force of your paddle will push the water which will apply an equal force back on you. There is very little resistance to this motion because there is a limited _______ force between the canoe and the surface of the water due to the smooth surface
Answer:
frictional
Explanation:
This scenario follows Newton's third law of motion which alludes to the fact that for every force or action exerted by a person on a body there is an equal and opposite reaction exerted back.
Because there is a limited frictional force (a force exerted by an object when an object moves across it) between
the canoe andwater surface (the opposite force/reaction)Here, the paddle helps the boatman apply a force on the water, resulting in the opposite amount of force been sent back; pushing the boat forward.
