Answers

Answer 1

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

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.

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.

Hope this helped :)

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!

B. Each parent only passé down one half it’s hereditary factors to 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.

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!
While what the other person said is correct, the true reason is because aerobic respiration is sustainable.

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.
