Answer:
A. Mitochondrion
B. Cytoplasm
C. Nucleus
D. Chloroplast
Explanation:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions
The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth.
B - Cytoplasm (gel like substance in which the organelles are suspended. Where most chemical reactions occur)
C - Nucleus (controls cells activity and contains DNA)
D - Mitochondria (where aerobic respiration occurs providing energy for the cell)
E - chloroplasts (where photosynthesis happens. Contains chlorophyll which absorbs sunlight for photosynthesis)

Why would an organism prefer aerobic respiration as opposed to anaerobic respiration (fermentation)?
Answers
Answer:
Advantages of Aerobic Respiration
With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.
Explanation:
Mark as brainlest answer!Anerobic respiration will produce 36 ATP faster than aerobic, but it will also produce lactic acid, which is toxic for cells (hint- it’s an acid)
This is why an organism would prefer aerobic respiration. Anaerobic fermentation would also produce toxic lactic acid.

The easiest way to think of this is to imagine a bird with a wide jaw and a hooked beak that solely eats caterpillars. This would not be a problem for the bird if they are in the open air, but if they go into a crevice, or they go into a hole of a tree, they will be impossible to get.

Many small poisonous animals are brightly colored, including the poison dart frog and some species of fish, octopi, and insects. What is common in their environments that would lead to these different animals having a similar trait?
Please answer in complete sentences at least 3 or 4.
Thank you! I’m working on other things for my classes which is why.
Answers
Many small poisonous animals are brightly colored, including the poison dart frog and some species of fish, octopi, and insects share same environment and habitat (aquatic).
What is an environment?When we discuss the environment we mean the world in our general surroundings that encompasses and influences all life on earth, including the air, natural ways of life, the water cycle, plants, creatures and different people.
Thus, share same environment and habitat (aquatic).

Answer:
BENEFITS:
The Descriptive investigation is used to describe a natural system when nothing or very little is known about the system. Like observing a new specimen in the microscope and describing it by observing the specimen.
A comparative analysis is used to compare two or more variable in nature by collecting data like observing the different colors of the rocks. It provides the data to show the similarity and dissimilarity of the population.
The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.
LIMITATIONS:
descriptive method of investigation
It cannot be used to correct variable or be used to determine causes and effect of the problem
experimental method of investigation
It might create an artificial situation that do not always represent the real life situation
comparative method of investigation
It is not easy to control other variables that might influence the study
How do mutations lead to genetic variation within a species?
O A. Making exact copies of DNA increases the rate at which parents
can produce offspring.
B. Changes in DNA produce genetic traits that can be passed on to
offspring.
C. Making exact copies of DNA increases the total number of
organisms in a population.
OD. Changes in DNA prevent organisms from surviving long enough to
reproduce.
Answers
Answer:
B. Changes in DNA produce genetic traits that can be passed on to offspring.
Explanation:
biodiversity
Answer:
B. Changes in DNA produce genetic traits that can be passed on to
offspring.
Genetic variations that alter gene activity or protein function can introduce different traits in an organism.

What did Mendel's cross-pollination of pea plants prove?
A. Inherited factors combine in offspring to create entirely new characteristics.
B. Each parent only passes on one-half of its hereditary factors to each offspring.
C. There is no such thing as a true-breeding plant; they all have hidden factors.
D. It takes four generations of offspring to identify the parents' factors.
Answers
Answer:
B. Each parent only passes on one-half of its hereditary factors to each offspring.
Explanation:
Pea plants have both male and female reproductive organs. As a result, they can either self-pollinate themselves or cross-pollinate with another plant. In Mendel's experiments, he was able to cross-pollinate purebred plants with particular traits and observe the outcome over many generations.
As a little fun fact; as we know, both human parents have 46 chromosomes, and when reproduction occurs, they both give half of their chromosomes (23) to their offspring!
A group of students is studying the types of plants that grow in a meadow next to their school. The meadow is mowed regularly, but it does not get any water other than rainfall. The meadow has several kinds of plants that are typically found in a grassland ecosystem. The plants include grass and clover. But there aren't any trees. The meadow has insects, including ants. Earthworms live in the soil. Garter snakes and mice also live in the meadow.

Give three ways that photosynthesis and respiration are dependent on one another.
Answers
Answer:
Both processes use and produce ATP in reactions that are carried out on membranes and are controlled by enzymes. Photosynthesis and respiration both involve cycles of reactions, involving redox reactions. The processes both use the same coenzymes, such as NAD and NADP.
Explanation:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Nah i can give u one tho
Answer:
products of one systeme are the reactants of the other!
Explanation:
The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
