Why are ORGANS classified?
Answer:
An organ is a group of tissues with similar functions. ...
A given organ's tissues can be broadly categorized as parenchyma, the tissue peculiar to (or at least archetypal of) the organ and that does the organ's specialized job, and stroma, the tissues with supportive, structural, connective, or ancillary functions.

2. Why do you think corals have declined since 1977?
Answer:
Written below.
Explanation:
Coral and fish communities showed dramatic declines from 1977 to 1996 due to massive harbor construction and suboptimal land management practices on the watershed. More recently, corrective measures in the form of watershed stabilization and fishing regulations have been implemented.
Coral reefs are endangered by a variety of factors, including natural phenomena such as hurricanes, El Niño, and diseases; local threats such as overfishing, destructive fishing techniques, coastal development, pollution, and careless tourism; and the global effects of climate change—warming seas and increasing levels.
Why is pH so important to maintain life?

D ) Earth’s energy budget will be balanced.
How can you increase the rate of a reaction? Select all that apply. *
Introduce a catalyst
Increase temperature
Increase the concentration of products
Decrease concentration of reactants
Answer:
- Increase the concentration of the reactants
-increase the temperature
- introduce a catalyst
The rate of reaction is increased by:-
Increase the concentration of the reactantsincrease the temperatureintroduce a catalyst.What is the rate of reaction?The speed at which a chemical reaction occurs is known as the reaction rate or rate of reaction. It is proportional to the rise in product concentration per unit of time and the fall in reactant concentration per unit of time. Reaction times can differ wildly.
A chemical reaction is a procedure that causes one group of chemical substances to change chemically into another.
The rate of a chemical reaction can be increased by Increasing the concentration of the reactant by increasing the temperature and by introducing a catalyst.
Therefore, the rate of reaction can be increased by doing the actions explained above in the answer.

True of false: Radiant energy reaches the earth in the from of both visible and invisible electromagnetic waves.
Answer:
TRUE OR FALSE : ) IT'S TRUE
EXPLAIN:
Radiation
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat. Radiant energy spreads out from its source in all directions. ... GAMMA RAYS have more energy than XRAYS, Radio waves, microwaves and ultraviolet waves all have longer wavelengths than visible light. Both X rays and gamma rays have higher frequencies than ultraviolet rays.

When a car suddenly stops at a red light, a book lying on the car seat slides forward. Why does the book continue to move forward?
A: The car moves in reverse more rapidly than the book.
B: The friction of braking transfers energy to the book
C: The book’s inertia causes it to continue moving
Answer:
C
Explanation:
The answer is c because Newton’s third law states “ for every action there is an equal and opposite reaction.” Since the car quit moving the book did not stay at rest because there was a reaction.
Answer:
C
Explanation:
Newton's 1st law of motions states : " Intertia: A objects resistance to change. More mass= more intertia. Less mass= Less intertia.
it ALSO states that an object at rest will stay at rest, until an outside forces acts upon the object, forming an unbalanced force.
The car stopping suddenly is the outside force, and the book sliding forward is the intertia to change.
A cyclist turns a corner with a radius of 50m at a speed of 10m/s. What is the cyclist's acceleration?
Answer:
2 m/s^2
Explanation:
a = v^2/r
a = (10m/s)^2 / 50m
a = 2 m/s^2

A cyclist turns a corner with a radius of 50m at a speed of 10m/s. The cyclist's acceleration is 2 m/s².
What is acceleration?The rate at which an item changes its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is acceleration. The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g. It is a vector quantity whose strength or magnitude is determined by the norm and whose direction correlates with a plumb bob.
a = v²/r
a = (10m/s)² / 50m
a = 2 m/s²

a 0.15 kg baseball has a momentum of 0.78 kg*m/s just before it lands on the ground. What was the ball's speed just before landing?
The speed of the ball (i.e the velocity since it has a direction in a specified time) is 5.2 m/s before it landed.
From the given information,
the mass of the baseball = 0.15 kgthe momentum of the baseball = 0.78 kg m/sFor an object moving in a direction in a specified time, the momentum of the object is usually directly proportional to the mass and velocity.
∴
Momentum = mass × velocity
velocity = momentum/mass
velocity = 0.78 kgm/s ÷ 0.15 kg
velocity = 5.2 m/s
