What would most likely occur over time if new technologies gave us information that challenged what scientists currently understand about natural selection
Question options:
A new scientific law would be established and proven by the findings. A new scientific theory would be established and proven by the findings. A current scientific law would be revised based on the new findings. A current scientific theory would be revised based on the new findings.
Answer:
A current scientific theory would be revised based on the new findings.
Explanation:
If new findings came about and challenged the current theory of natural selection so that Darwin's theory didn't look like it was true at all, the initial theory(darwin's theory of natural selection) would not be entirely discarded but revised according to these new findings and then form a sort of backbone to this new theory which would be based on findings of many independent researchers and not just one. Example: how some of Sigmund Freud's theories or Aristotle's may not be entirely valid today but still works as a fundamental for understanding other theories.
The pharynx is the structure in the body that serves as a pathway of both air and food. How does the body make sure that food does not get into the lungs?
Answer: The body makes sure that food does not get into the lungs because the epiglottis closes the air pathway so that food will not enter it.
Answer:
food getting to the lungs will be aspiration
Explanation:
A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow hence preventing food from getting into the lungs

In what order does blood flow through the body and heart? A. Right atrium, left atrium, lungs, right ventricle, left ventricle, body. B.

Right atrium, right ventricle, lungs, left atrium, left ventricle, body.
Answer:
answer is D
l
Explanation:
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
The statement that describes the order blood flows through the body and the heart is:
Right atrium, right ventricle, lungs, left atrium, left ventricle, body.What is blood?It is a red liquid with different shades that varies according to the amount of oxygen it has inside, that is, hemoglobin.
Characteristics of blood circulationIt is a necessary substance for oxygenation to occur between cells, as well as to regulate blood pressure.Each side of the heart is divided into an upper chamber called the atrium and a larger, lower chamber called the ventricle.The blood flows since it has left the right ventricle, has been oxygenated by the lungs and has returned to the left atrium through the pulmonary veins, it is carried to the left ventricle.Therefore, we can conclude that the main function of the blood is to ensure that oxygen and nutrients are distributed between the cells of each organism.

If two individuals were heterozygous for freckles, which are a dominant autosomal trait, what percentage of their offspring would you expect to have freckles
Answer:
75%
Explanation:
Firstly, an autosomal dominant trait is a trait the becomes expressed in the presence of only one affected allele, which is the dominant allele. Freckles is said to be an autosomal dominant trait meaning that the presence of the dominant allele (F) makes a person have the condition.
According to this question, If two individuals that are heterozygous for freckles cross i.e. Ff × Ff, the following proportion of offsprings will be produced: FF, Ff, Ff and ff (see punnet square).
From the genotypic observation of the produced offsprings:
FF, Ff - possess freckles
ff - do not possess freckles
Since, 3 (FF, Ff and Ff) of 4 offsprings possess freckles, the percentage of offsprings expected to have the condition will be:
3/4 × 100 = 75%

The total number of molecules of ATP produced during glycolysis is ______, which results in a net production of _____ ATP.
Answer:
The answer is "4 and 2 ".
Explanation:
The overall glycolysis ATP number is 4 of one hydroxyl group. In the first part of the glycolysis 2 ATP molecules are used, so that 2 ATP molecules are net gained. 2. In addition, 2 NADH atoms in the glycol are also created. This is why the total ATP molecules produced during metabolism are 4, resulting in a net output of 2 ATP.

If you were working for a pharmaceutical company as part of a drug discovery team, which of these enzyme inhibitors would you suggest as a productive avenue for drug development? Group of answer choices a compound that inhibits enzymes by significantly changing the pH throughout the body a drug to treat diabetes that irreversibly inhibits an enzyme in the metabolic pathway to synthesize glucose a drug to treat high blood pressure that reversibly inhibits an enzyme catalyzing production of a chemical that causes blood vessels to contract a compound that acts as a competitive inhibitor for a digestive enzyme produced only in the presence of certain foods
Answer:
The correct answer is - a drug to treat high blood pressure that reversibly inhibits an enzyme catalyzing production of a chemical that causes blood vessels to contract.
Explanation:
In the given all the situation or conditions that is practical and possible it the drug that develop to treat high blood pressure by reversibly inhibiting an enzyme that catalyzes the chemical that leads to constirctions of the blood vessels.
These chemical cause blood vessel constrict and that leads to high blood pressure therefore inhibiting such enzyme that use to produce these chemical is a practicle solution for high blood pressure.

Is the cell an open or closed system? Explain your
answer using at least one example of a cell
organelle and its function
· In an open system matter and energy can be transferred
· In a closed system only energy can be exchanged
· In an isolated system neither matter nor energy can be exchanged
· The cell has to be an open system because it needs to exchange matter and energy and the only way to do so is through an open system
· As an open system the cell allows nutrients to enter the cell and waste products to exit the cell
· The cell does this through the use of a semi-permeable membrane
· It needs nutrients in the forms of glucose, ions and many other molecules.
· The nutrients can come into the cell through either passive or active transport
· In passive transport the nutrients naturally move from a higher concentration gradient to a concentration gradient.
· During active transport the particle need to move against the concentration gradient. To do this the cell needs energy to transport the materials. The energy comes in the form of ATP.
