Answer:
True.
Explanation:
Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.

Which is the following is true about saturated fats?
a. They are typically solids at room temperature.
b. They are generally the healthiest fats to consume.
c. They cannot be broken down by enzymes.
d. By definition, they always contain one or more double bonds.
The following is true about saturated fats: they are typically solids at room temperature, which is in Option A, as they have a high melting point due to the absence of double bonds in their fatty acid chain.
What are saturated fats?Saturated fats are a type of fat molecule that consists of long chains of fatty acids. These fatty acids are called "saturated" because they are fully "saturated" with hydrogen atoms, that is, there are no double bonds between the carbon atoms in the fatty acid chain. This results in a straight, rigid structure that allows these fats to pack tightly together, which is why they are usually solid at room temperature.
Hence, the following is true about saturated fats: they are typically solid at room temperature, which is in Option A.

Which of the following is not a function of carbohydrates?
a structure
b genetic material
c storage
d energy
Carbohydrates are the primary source of energy in living organisms. It is a macromolecule and one of the primary nutrients required by the body.
The functions of the carbohydrates are:
Carbohydrates such as cellulose are the primary component of the cell wall of plants, bacteria, and algae. The compound provides structural support to the cells. Carbohydrates such as starch and glycogen are stored and can be used as a source of energy in time of need. Carbohydrate like glucose is the primary compound in several enzyme-catalyzed reactions to yield ATP.Thus, the correct answer is Option B.

Osteoporosis is a disease that can cause bone weakening in women due to calcium loss. One group of patients will be taking the regular calcium pill used for treating osteoporosis. Another group of patients will be taking a new calcium pill used for treating osteoporosis. Calcium levels obtained by taking the new pill will be tested over a six month period and the women’s resulting bone mass will be compared between the two groups at the end of six months of treatment.
What is the Independent variable?
Answer:
The Independent variable would be the pills that are being taken.
Explanation:
The Independent variable is the variable that you control because the Dependent variables depend on what the Independent variable is.

how do materials that cannot diffuse through the cell membrane get into the cell?
The process of diffusion occurs when
A. all molecular movement stops.
B. molecules move from areas of lesser concentration to areas of greater
concentration
C. sugar molecules move into a cell.
D. molecules move from areas of greater concentration to areas of lesser
concentration.
Answer:
d
Explanation:
The process of diffusion occurs when molecules move from areas of greater concentration to areas of lesser concentration. The correct option is D.
What is diffusion?The movement of essential, small molecules across the cell membrane as well as the movement of materials within cells both depend on the process of diffusion.
The exchange of gases in the lungs and gills is regulated by this process. As a byproduct of biological metabolism, carbon dioxide is released by all cells.
For example, when you pour a red color drop into the water, slowly the color molecules are evenly distributed in the whole water. It does not need any energy because it works according to the concentration gradient.
Thus, the correct option is D. molecules move from areas of greater concentration to areas of lesser concentration.

explain how the energy producing processes occurring in the cells of organisms drives the cycling of matter within an ecosystem
Answer:
The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon based organic molecules and release oxygen

Urey and Miller cooked a "Primordial soup" with Hadean gases, water and electricity to make ___, ___, ___, and ___.
Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make glucose, acetic acid, amino acids and lipids.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.

D. uses mitosis
Explanation: here is the Wikipedia explanation im not good at explaining
Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding. With their single-celled growth habit, yeasts can be contrasted with molds, which grow hyphae. Fungal species that can take both forms (depending on temperature or other conditions) are called dimorphic fungi.
Answer:

Explanation:
First of all, you're not "dumb"!
Yeast reproduction happens relatively quickly (in a matter of hours, not a matter of days). It CAN occur by mitosis, but most often occurs by a process called budding.
Humans have a "slow" reproduction - it takes 9 months just to produce a single organism!
