A pulley was used to lift wood that weighed 3892 N. The force applied to the pulley was 274 N. What is the mechanical advantage of the pulley?

Answers

Answer 1

Answer:

1946/137

Explanation:

I would say this would go under physics rather than biology.

The mechanical advantage is found by the ratio of the output force to the input force. Writing this as an equation will be MA = F_o/F_i where F_o is the output force and F_i is the input force. Solving for MA with the information we have, we get: MA = 3892/274 = 1946/137

new chemical reactions.

Answers

Answer:

Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.

Explanation:

Brainliest please?

Answer:

[tex]\boxed {\boxed {\sf H. \ Enzymes \ act \ as \ catalysts \ to \ drive \ chemical \ reactions \ forward}}[/tex]

Explanation:

Enzymes are catalysts.

They lower the activation energy required to carry out a reaction, which speeds up the reaction. They attach to a molecule known as a substrate at the active site in a specific way.

Enzymes are incredibly important for life. Many reactions wouldn't occur at a rate that can support life, but enzymes allows this to happen. They assist in digesting food, replication genetic material, and more.

So, we know that enzymes are catalysts that make reactions efficient. Therefore, choice H is the best answer.

A ball is dropped from height of 45 m. A second ball is thrown downwards from the same
with an initial vity both the balls reach the ground at the same time, culate the value of u​

Answers

Answer:

h = 45 m

g(acceleration due to gravity) = 9.8 m/s^2 or 10 m/s^2

Final velocity ( v ) = 0 m/s

v = ?

we know theirs equation of motion, v^2 = u^2 + 2gh

0 = u^2 + 2(-10)(45) [ The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing.]

0 = u^2- 900

900 = u^2

u = √900 = 30 m/s

How do algae blooms destroy aquatic life?

by giving off toxins that kill life

A harmful algal bloom (HAB) contains organisms (usually algae, hence the name) that can severely lower oxygen levels in natural waters, killing marine life.

What, besides temperature can make ocean water significantly denser

salinity

High salinity makes water denser. This is because there is more salt packed into the water. High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense.

Which area best describes a continental slope?

Continental slopes are regions of steeply sloping seafloor that lie between continental shelves and the deep ocean basins (Figure 2). Regional gradients are typically 2–5°, but locally slopes may be much steeper.

Algae blooms destroy aquatic life because of the decomposition of algae depletes oxygen needed by organisms.

How do algae blooms destroy aquatic life?

When algae and bacteria in an algal bloom die, the decomposition process consumes the surrounding oxygen which leads no presence of oxygen in the water body and the aquatic organisms die because of suffocation.

So we can conclude that Algae blooms destroy aquatic life because of the decomposition of algae depletes oxygen needed by organisms.

Understanding how populace attributes, for example, size, spatial dissemination, age structure, or the birth and demise rates change over the long haul can assist researchers or legislatures with simply deciding.

What benefit does an organism gain by only using this method of reproduction?

Answers

Explanation:

In a stable or predictable environment, asexual reproduction is an effective means of reproduction because all the offspring will be adapted to that environment. In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions. On the other hand, the rapid rates of asexual reproduction may allow for a speedy response to environmental changes if individuals have mutations. An additional advantage of asexual reproduction is that colonization of new habitats may be easier when an individual does not need to find a mate to reproduce.

Which statement below explains why water is insoluble in the middle of the semipermeable membrane.

The membrane is made from polar phospholipids allowing water to move freely in and out of the cell

Answers

Answer:

The membrane is made from polar phospholipids allowing water to move freely in and out of the cell

Explanation:

The cell membrane is the organelle of the cell that allows for substances to be transported into and out of the cell. It is able to do this due to its semi-permeability. The membrane contains a phospholipid component, which contains a polar region that allows for polar substances such as WATER to enter and leave the cell.

The polarity of the phospholipid component of the cell membrane explains why water is insoluble in the middle of the semipermeable membrane.
