Lipids contain more energy that carbohydrates because they contain more carbon to hydrogen bonds to release energy when broken.

<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

The safe steps in cooking, food handling, and storage are important to prohibit foodborne ailments. One cannot taste, smell, or see the harmful bacteria, which may result in illness.

In every step of food preparation, there is a need to follow the four steps of the Food Safe Families campaign to maintain the safety of food. These are clean, separate, chill, and cook.

In the given case, there is a need to cool the soup correctly in a cooler or fridge, and then reheating it on the stove at about 165 degrees F within two hours.

3. In Module 1.3 Cell Types, examine the illustrations of six specific cells: a neuron, red blood cell, osteocyte, skeletal musc

andreyandreev [35.5K]

Answer:

Please find the similarities and differences between these cells below.

Explanation:

According to this question, six specific cells are examined. They are: neuron, red blood cell, osteocyte, skeletal muscle cell, sperm cell, and egg cell.

SIMILARITIES:

These cells are cells that make up different tissues and systems in living organisms. They perform different functions in their respective locations, however, they are similar in the sense that they all possess some cellular components called organelles. The organelles that are common to all these types of cells are CELL MEMBRANE, RIBOSOMES, MITOCHONDRIA, GENETIC MATERIAL (DNA), NUCLEUS,

They also possess two set of chromosomes in their nucleus i.e. diploid.

DIFFERENCES:

However, they differ in their functions. For example;

- neuron: nerve cell whose function is related to the nervous system

- red blood cell: blood cell whose function is related to circulatory system

- osteocyte: bone cell whose function is related to the skeletal system

- skeletal muscle cell- muscle cell whose function is related to the muscular system

- sperm cell: a male sex cell whose function is related to reproduction

- egg cell: a female sex cell whose function is related to reproduction

Electron carrier molecules transfer electrons between metabolic pathways. Choose the electron carriers that transfer electrons f

denis23 [38]

Answer:

from glycolysis to electron transport.-glycolytic pathway

NADH and FADH2 are the major electron carrier from glycolysis through the Kreb Cycle to the electron transport chain.

Note-NADH alone transports electron from glycolysis to the Kreb Cycle. while both NADH and FADH2 transport electrons from the kreb'cycle to the electron transport chain.

from citric ac id cycle to the electron transport chain.

as explained above both NADH and FADH2.

The electrons are in the hydrogen atoms, carried by these co-enzymes. When they reached the matrix, the hydrogen atoms are split into protons and electrons(p and e-). it is these electrons that form gradients which are transported as chains in the matrix. The gradients of the electron generated PMF for pumping Hydrogen atoms into the intramembrane of mitochondrial

Note.

There are at least two things related to barb's medical history that may be of interest to a doctor. what are those two things?

Triss [41]

The two things that the doctor may be of interest to barb’s medical history is her hip replacement procedure and her asthma. Although her hip replacement procedure was done long ago but she should still be cautious on her movements especially carrying her grandchildren or bringing heavy load. Moreover, her asthma attack must also be carefully monitored particularly her labored breathing pattern.
