Which type of bonds form between the oxygen and hydrogen atoms of within a water
molecule
Answer:
covalent bonds
Explanation:
Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other. Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge. The area around the oxygen is somewhat negative compared to the opposite, hydrogen-containing end of the molecule, which is slightly positive.
To be considered living, an organism must ____.

Identify two examples of foods that contain high amounts of
each of the following macromolecules: carbohydrates, lipids, and proteins.
Answer:
Carbohydrates: pasta and rice, both very starchy
Lipids: beef and bacon, both have animal fat in themm which contains lipids
proteins: eggs and beef, lots of animal derived foods contain proteins since thy are the basis of life.
Explanation:
Here are two examples for each of the three macromolecules; Carbohydrates; Bread, Rice. Lipids (Fats); Avocado, Salmon. Proteins; Chicken Breast, and Beans.
Carbohydrates;
Bread; Bread is rich in carbohydrates, primarily in the form of starch. It provides a quick source of energy due to its high carbohydrate content.
Rice; Rice, especially white rice, is another significant source of carbohydrates. It is a staple food in many cultures and contributes to daily energy intake.
Lipids (Fats);
Avocado; Avocado is a fruit that contains healthy monounsaturated fats. It is often used in salads, spreads, and various dishes.
Salmon; Salmon is a fatty fish that provides omega-3 fatty acids, which are essential for heart and brain health.
Proteins;
Chicken Breast; Chicken breast is a lean source of protein, low in fat. It is commonly consumed for its high-quality protein content.
Beans; Legumes such as beans (e.g., kidney beans, black beans) are rich in plant-based proteins. They are a staple in many vegetarian as well as vegan diets.

Which type of biomolecules are made up of fatty acids?
a. carbohydrates
b. proteins
c. lipids
d. nucleic acids
Answer:
c. lipidsExplanation:
As,
A lipid is a phospholipid, a major structural component of all cell membranes. It is composed of a glycerol molecule, two fatty acids
The type of biomolecule that is made up of fatty acids is Lipids and thus, option C is the correct answer.
Nucleic acids, Lipids, Proteins, and Carbohydrates, are some of the significant biomolecules. The characteristics of lipids are listed as follows:
The organic molecule that is specifically related to fatty acids and can be able to dissolve only in organic solvents and not in water are called lipids. The lipid molecule is composed of 1 molecule of glycerol and 3 molecules of fatty acids that are linked to one another. Oils, waxes, fats are some examples of lipid molecules.Thus, we can conclude that lipids are the type of biomolecules which is made up of fatty acids.

How would cellular respiration be impacted in the absence of photosynthesis?
Only aerobic respiration would take place.
Only anaerobic respiration would take place.
Fewer ATP would be produced during cellular respiration.
Both reactants of cellular respiration would not be available.

Explanation:

it was correct.
photosynthesis and cellular respiration work together to create the life cycle. without Cellular respiration we would die and without photosynthesis we would die. They are equally important without one the other could not function
have a great day
:)
Only anaerobic respiration would take place in the absence of photosynthesis, hence option B is correct.
What is the relation between cellular respiration and photosynthesis?Oxygen and glucose are used in cellular respiration to create carbon dioxide and water. The equation for photosynthesis is the inverse of the equation for cellular respiration, further emphasizing this concept.
The cycle of cellular respiration and photosynthesis is essential for the survival of humans, animals, and plants. The term "cellular respiration" describes a chain of metabolic processes that convert glucose into water and carbon dioxide and ATP.
Therefore, in the absence of photosynthesis, there would be no glucose or oxygen for respiration, and since photosynthesis requires carbon dioxide, only anaerobic respiration would be possible.

In your own words, discuss the importance of enzymes within a living system and include what the function of an enzyme is. Using your best grammar, write 2-4 sentences.
Answer
Enzymes are proteins that act as biological catalysts that increase the rate if a reaction by decreasing the amount of energy needed to speed up the reaction. Enzymes help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. Enzymes build muscle, destroy toxins, and break down food particles during digestion.

Many populations exhibit the following growth curve.
Which statement(s) below accurately are describing the growth as shown on the graph. NOTE: There is MORE THAN ONE correct answer. Choose ALL that apply.
Select 3 correct answer(s)
Question 5 options:
Phase B of the graph is showing a population that has reached its carrying capacity.
When both phases of the graph are looked at together, it shows logistical growth of a population after growing exponentially and reaching its carrying capacity .
Phase B of the graph is showing exponential growth only.
The entire graph shows two organisms competing for space.
Phase A of the graph is showing exponential growth only.
Many populations exhibit the following growth curve.. Here option 1, 2, 3 are correct which describe the growth. Phase B of the graph is showing a population that has reached its carrying capacity.
What is carrying capacity ?
The carrying capacity of the individual is the maximum number of population size of the species in a sustainable environment which is indefinitely reach up to the limit of no further growth.
Carrying refers to support and Capacity means it is the ability of an organism to reproduce the maximum output, when population reaches the limit of carrying capacity then the mortality will be greater than natality.
The importance of Carrying capacity is mainly focused on the concept of sustainability, imbalance in the environmental and Global warming which are the causative agent, eradication of poverty and practices are also increase the importance of carrying capacity.

use the concept of natural selection to explain why organisms typically adapt over time
Answer:
natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species
Explanation:
Answer:
Natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species. Eventually, the more favorable traits are incorporated into a species as the organisms that had those traits survive while the ones who do not die. This process takes time because it occurs through individuals with the favorable traits passing those traits on to future generations. Typically, the less favorable traits will not be eradicated in one generation.
