Pls help!!!
Bingel [31]

Answer:

Try this.

Explanation:

       I'm not too sure because the teacher never gave me enough information (Need Bigger Graph). Get bigger graph paper as it says "The X-axis should be years and the Y-axis should be coal production." On the X-axis (Horizontal Line) write "Years" and on the Y-Axis (Vertical Line) write "Coal Production."

Now, your gonna start listing all the years on the X-Axis 1996 through 2011, And on the Y-Axis list all the coal productions 145 and all the numbers through 634. Make sure you have the regions, Appalachian, Interior and Western.

     I'm sorry if this didn't help, this is what I did and it helped me, I thought it might help you too.

Given a population that contains genetic variation, what is the correct sequence of the following events under the influence of
GuDViN [60]

Answer:

2. A change occurs in the environment.

4. Poorly adapted individuals have decreased survivorship.

1. Well-adapted individuals leave more offspring than do poorly adapted individuals.

3. Genetic frequencies within the population change.

Explanation:

The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.

Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.

Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.

Hence, the sequence of events is 2, 4, 1 and 3.

Which are the three main types of lipids
maxonik [38]

Answer:

The three main types of lipids are - triglycerides, diglycerides, and steroids.

Explanation:

Lipids are organic compounds that are fatty acids or their derivatives. Lipids are insoluble in water but soluble in organic solvents (alcohol, ether). The three common lipids are triglycerides, diglycerides, and steroids.

An ester derived from glycerol and three fatty acids is a triglyceride. These are the main component of body fat in the vertebrates as well as the vegetable fat.

A Glyceride consisting of 2 fatty acid chains bonded to a glycerol molecule covalently through ester linkages is a diglyceride.

Biologically active organic compounds with four rings arranged in a specific molecular configuration are steroids.

the protein hemoglobin carries oxygen from the lungs to the tissues. this is an example of protein's role in
xxTIMURxx [149]

Red blood cells contain a protein called hemoglobin. An illustration of red blood cells showing the hemoglobin protein. This protein serves as a transporter of oxygen from the lungs to tissues.

<h3>What are proteins?</h3>

The term "protein" refers to a macro- and large-scale biomolecule that has one or more lengthy chains of amino acid residues.  An amino acid chain makes up the basic building block of proteins.

When oxygen binds to the heme portion of the hemoglobin molecule in red blood cells during physiological respiration, oxyhemoglobin is created. This procedure takes place in the pulmonary capillaries close to the lung's alveoli.

Thus, red blood cells contain a protein called hemoglobin. An illustration of red blood cells showing the hemoglobin protein. This protein serves as a transporter of oxygen from the lungs to tissues.
