What is a muscle group that performs opposite functions called?

Answer:

d

Explanation:

Environmental science can answer all the questions about natural phenomena by analyzing and observing the world and testing ideas about it. Thus, the correct option is D.

Environmental science is an interdisciplinary academic field of science which integrates different disciplines such as physics, biology, and geography to the study of the environment as a whole, and the solution of environmental problems. Environmental science has emerged from the fields of natural history and medicine during the Enlightenment period.

Environmental science has the ability to answer all the questions about the natural phenomena by the analysis and observation of the world and by testing the ideas about it.

Therefore, the correct option is D.

Explanation:

The overall shape of an enzyme changes after the attachment with the substrate.

Enzymes are proteins composed of amino acids that linked together in one or more polypeptide chains. This sequence of amino acids in the form of  polypeptide chain is known as the primary structure of an enzyme.

The tertiary structure is the enzyme's overall three dimensional structure, which occurs due to interactions between the R groups of the amino acids that make up the protein and the active sites of the substrate with which the enzyme can attach so we can conclude that the overall shape of an enzyme changes after the attachment with the substrate.

The primary structure of enzymes determinies their functions and their secondary and tertiary structures. R groups remain in the center of the molecule and stabilize the structure.

--------------------------

To answer this question, we need to remember that enzymes are proteins, and hence, they share many properties. From now on, we will refer to the enzyme as proteins or molecules.

Amino acids are organic molecules. They are composed of a central carbon, one hydrogen atom, one carboxyl group (COOH), one amine group (NH2), and one R group.

The composition of the R group is what makes them different from each other.

Proteins are amino acid polymers linearly arranged and connected by peptidic bonds. These molecules characterize by their different structures.

The peptidic bond is the union of two amino acids by their carboxyl and amine groups.

The R group of each amino acid is involved in stabilizing the molecule through their interactions.

The amount of amino acids that compose the polypeptide and their order in the chain determines the primary structure of the protein. The primary structure of the proteins determines the tertiary one.

Protein functions also depend on the aminoacids sequences. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.

The primary structure refers to the sequence in which the amino acids are arranged in the chain.

The secondary structure is the folding that the polypeptide chain adopts thanks to the formation of hydrogen bonds.

The three-dimensional structure makes them even more stable in the environment and capable of properly accomplishing their biological role.  

When proteins are composed of more than one polypeptide subunit, they arrange in a fourth structure, named quaternary structure.

The hydrophilic R-groups remain in the center of the molecule, facing the protein interior, and avoiding interaction with water.

Answer:

Lymphatic Capillaries are slightly larger in diameter than blood capillaries, and have closed ends (unlike the loop structure of blood capillaries). Their unique structure permits interstitial fluid to flow into them but not out.

Explanation:

Answer:

Until the past decade, scientists, research institutions, and government agencies relied solely on a system of self-regulation based on shared ethical principles and generally accepted research practices to ensure integrity in the research process. Among the very basic principles that guide scientists, as well as many other scholars, are those expressed as respect for the integrity of knowledge, collegiality, honesty, objectivity, and openness. These principles are at work in the fundamental elements of the scientific method, such as formulating a hypothesis, designing an experiment to test the hypothesis, and collecting and interpreting data. In addition, more particular principles characteristic of specific scientific disciplines influence the methods of observation; the acquisition, storage, management, and sharing of data; the communication of scientific knowledge and information; and the training of younger scientists.1 How these principles are applied varies considerably among the several scientific disciplines, different research organizations, and individual investigators.

Because each chromosome is made from a single molecule of 'DNA', before a cell divides itself, it had to replicate and copy its DNA. This makes it so that after cell division, each new cell holds an exact copy of the genetic material from the original cell.

Explanation:

An F1 cross between true breeding brown and white lines is set up. What evidence would best support white fur being dominant to brown -----

The best evidence to show that white fur being dominant is when all the offspring after the cross are white instead of brown

They are therefore expected to produce heterozygous lines.

The evidence that would best support white fur being dominant is when all the lines produced are white despite being heterozygous.

A dominant trait is known to mask the expression of other traits.

I got asked this question <3

In this exercise it is necessary to fill the gaps with the correct given word. So, the right order of words will be:

1. microscope

2. eyepiece

3. objective

4. mirror

5. stage

6. clips

7. specimen

8. coarse adjustment knob

9. slide

10. image

11. fine adjustment knob.

So, after filling all the gaps, the text and, consequently, the final answer will be:

1. Put a table lamp in front of the microscope.

2. Put a low-power (, e.g., x5) eyepiece into  the microscope.

3. Rotate a low-power (e.g., x4)  objective into position.

4. Look through the eyepiece. Adjust the mirror until you see a bright circle of light.

5. Place a slide on the stage, and fix it with the clips. The specimen on the slide should be right above the hole of the stage.

6. Look at the microscope from the side. Turn the coarse adjustment knob

carefully to lower the objective until it is very close to the slide.

7. Look through the eyepiece. Turn the coarse  adjustment knob to raise the objective slowly until  you can see an image of the specimen.

8. Turn the fine adjustment knob to get a sharper image. The image is now in focus.
