Explanation:
In biological molecules, carbon,nitrogen, oxygen often form covalent bonds with hydrogen.Arrange these Bonds from most polar to least polar: C-H, N-H,O-H
Answer:
The order of polarity from most polar to least polar is as follows:
O-H > N-H > C-H
Explanation:
The polarity of a substance is a function of the charges of the ionic elements that makes up the substance. A bond between two ions is considered polar if it is between a negatively charged and positively charged ions. Hence, the stronger the charges of the ions in the bond, the more the polarity.
In this question, hydrogen is said to form covalent bonds with carbon, oxygen and nitrogen in biological molecules. However, the covalent bonds formed will not possess the same degree of polarity.
The bond between oxygen and hydrogen (O-H) is considered most polar amongst these three because OXYGEN atom is the most electronegative among the three ions. Hence, it will pull more electrons to itself and make the hydrogen ion more electropositive. This is followed by the bond between nitrogen and hydrogen (N-H) because nitrogen is more electronegative than carbon. The least polar is the bond between carbon and hydrogen as carbon is the least electronegative, hence, will not be able to pull electrons from hydrogen effectively.
The order from most polar to least polar is: O-H > N-H > C-H

Hummingbirds are an example of a _____ because of the pollination they provide.
Answer:
The correct answer is "pollinator".
Explanation:
Insects are the first animals that come to mind when we think about pollinators, however hummingbirds are an excellent example of pollinators as well. Hummingbirds feed frequently from flowers, transferring grains of pollens from a flower to others. Some species of flowers have adapted to develop some traits to attract hummingbirds, such as certain color, shape and scent.

For something to be considered living, it must be composed of at least one what?
Answer:
[tex]\boxed {\tt Cell}[/tex]
Explanation:
There are many characteristics of life, including, cells. A cell is a tiny unit of life that carries out many different processes.
If something is considered living, it must have at least one cell, but it can have more. For example, bacteria is unicellular and living. We (humans) are also living, but made of billions of cells.
Therefore, for something to be considered living, it must be composed of at least one cell.
Nicholas has been biting his nails since he was a kid. He wants to break the habit so he puts bitter-tasting nail polish on his left hand and leaves his right hand without polish. After 3 days he notices his nails on his left hand have grown but he continued to bite his right-hand nails.
A. Independent Variable=
B. Dependent Variable=
C. Control=
Answer:
Independent: Putting the nail polish
Dependent: nail growth
Control: right hand, without polish
The experiments are known to have various variables. In Nicholas's case, nail polish is an independent variable, nail growth is a dependent, and right nails without polish are a control.
What are independent variables?Independent variables are defined as the test variables that in an experiment are not constant but are kept varied and manipulative causing various effects on the result of the hypothesis. Putting the bitter nail polish on the nails of the left hand is a test variable.
The dependent variable (outcome variables) along with independent results in cause and effect and are conditional on the independent factors. The length of nails is dependent as it is affected by the nail-biting.
On the other hand, the control variables are constant in that the factors are limited so that they do not interfere with other factors that affect the outcome. Fingernails on the right hand with no polish are controlled.
Therefore, nail polish is an independent variable.

Which feature do amber fossils have that mold fossils do not?
O preserved soft tissue
O organisms turned into rock
O solid copies of the original organism
O impressions of hard tissue left by organisms
Answer: preserved soft tissue
Explanation: just took the test!
The feature do amber fossils have that mold fossils do not preserved soft tissue. Thus, option A is correct.
What are fossils?
The fossil can be defined as the compression of the animal, plant or some organism that was living. It is compressed by the rocks or or settled in the water bodies in the form of sediments. The fossil residues have some of the carbon left in it.
This carbon is estimated by carbon dating in order to get the age of the fossil.The preserved fossils have carbon residue left which can be used as a source of information.
There are several types of the connective tissues: bones, ligaments, tendons, cartilage, and adipose tissue. In the foot, among all connective tissues, ligaments and tendons are the most abundant types. Ligaments and tendons mostly consist of densely packed collagen, which is the main structural protein of the connective tissues.
Therefore, The feature do amber fossils have that mold fossils do not preserved soft tissue. Thus, option A is correct.

3. Label the three planes in the following image next to the three corresponding letters below the image.
CI
a)
hlwhos on this Imao ??
Answer:
The correct labels of the three planes are -
a. axial or transverse plane.
b. sagittal plane
c.. coronal plane
Explanation:
The human body can be divided into three planes on the basis of anatomy - the sagittal plane, the coronal plane, and the transverse plane
A sagittal plane is a longitudinal plane that divides the human body in the left and right parts.
A coronal plane is an anatomical plane that divides the body vertically into the back and front, ventral or dorsal (to be more specific).
An Axial or transverse plane, it is the plane that divides in the upper part of the body and lower part of the body.
Thus, the correct answer is -
a. axial or transverse plane.
b. sagittal plane
c. coronal plane

Which objective is referred to as the "scanning objective"?
Answer:
This question lacks options; they are:
a. 4x b. 10x c. 20x d. 100x
The answer is A
Explanation:
The objective lens is an integral part of a light microscope as it provides the viewer with the picture or image of the specimen. There are several types of objective lens depending on their magnification.
The lowest possible objective lens with the power of 4x is called the SCANNING OBJECTIVE. In combination with the eye/occular lens, it provides a magnification of 4x × 10 = 40x. The name of this lens comes from the fact that it provides a full scan of every part of the specimen being viewed before diversifying into a specific region by changing the objective.

Diffusion is an example of
a) passive transport
b) phagocytosis
c) endocytosis
d) active transport
Explanation:
Diffusion is an example of
a) passive transport
Answer:
[tex]\boxed {\tt A. \ Passive \ transport }[/tex]
Explanation:
First, let's define diffusion.
Diffusion is the movement of particles from areas of high concentration to low concentration. This movement is also known as moving down a concentration gradient. This process of diffusion occurs without any energy.
Since it doesn't require energy expenditure, diffusion is an example of passive transport.
Therefore, the correct answer is A. passive transport.
