Biology
1 answer:
adell [148]3 years ago
7 0

Answer:

The ball has greater velocity before the collision, so the force affects the ball more than it affects the bat. The ball has less mass, so the equal force on the ball and the bat causes greater acceleration of the ball. The bat exerts more force than the ball because the batter is exerting a force on the bat as it hits the ball

How does smoking make an individual more susceptible to infections?
Elenna [48]

Answer:

The active smokers and those getting exposed, that is, passive smokers are at enhanced threat of bacterial infections. Getting exposed to tobacco smoke enhances vulnerability to respiratory tract infections, comprising pneumonia, tuberculosis, and Legionnaires disease.  

Smoking compromises the anti-bacterial activities of leukocytes incorporating monocytes, neutrophils, B cells, and T cells, thus, demonstrating the mechanism for enhanced risk of infections.

How do enzymes act as catalysts? (Choose ALL that apply) They allow for fewer collisions of molecules (enzymes + substrates) The
vazorg [7]

Answer:

- They allow for more collisions of molecules (enzymes + substrates)

- They lower the amount of activation energy needed to complete the reaction.

- They speed up chemical reactions to form more products

Explanation:

Enzymes are proteinous molecules that serves as catalyst in living systems. Like every other catalyst, enzymes function to SPEED UP the rate of biochemical reactions by LOWERING/REDUCING the activation energy, which is the energy required for a reactant to form product (completion of reaction).

Enzymes like other catalysts causes faster movement of molecules in the reaction i.e. they allow for more collisions of molecules (enzymes + substrates). This causes the rate of reaction to increase and hence, speeden the reaction.

Suppose a newborn baby was accidentally mixed up in the hospital. In an effort to determine the parents of the baby, the blood t
Sladkaya [172]

Answer:a. Draw Punnett squares for each couple (you may need to do more than 1 square/ couple)

Baby 2 MUST belong to the Browns because Mr. Brown is the only parent with an A allele to

contribute… then the rest works out as follows:

b. To which parents does baby #1 belong? Why? Hint you may want to refer to your Punnett

squares.

Baby 1 must belong to the Smiths, because they are the only ones with the possibility of EACH

having a recessive allele to pass down to the baby, Mr. Brown has type AB blood and therefore

only has the dominant A and dominant B alleles – no recessive allele possible.

Why is it important to study the theory of plate tectonics and continental drift?
Dvinal [7]
It is practical knowledge in the sense that we know why some parts of the world are inherently risky to live in. Even though volcanic eruptionis, earthquakes and tsunamis are difficult to predict, it makes sense to have building codes and emergency plans that take this into account.

It is science’s response to the beliefs that natural catastrophes (volcanism, earthquakes and tsunamis) are divine punishments for the evil ways of some individuals.

Even if you will never use or apply this knowledge, knowing about the theory of plate tectonics gives you a current scientific perspective on what we know about the natural world.

It is a good example of how scientific theories proceed by trying to fit several observations into a coherent explanation.

Learning about the observations that needed to be made and explained for the theory to win over scientists helps caution you against people who adopt belief systems without questioning the myths told to them, or those who try to profit from ignorance of how nature actually works.

When it is well taught, it should convince you that, like any scientific theory, plate tectonics is a “work in progress”. New discoveries continue to be made, and it takes creative and logical thinking, debate and a quest for more observations in order to determine which ones prove or challenge the current theory and which ones may lead to its refinement.
