What would happen to the digestion process if enzymes were not present
Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.

Meryl is making a collage of pictures for her science class. On one-half of a piece of poster board, she is attaching pictures of the result of adding heat to materials. On the other side of the poster, she is attaching pictures of the result for removing heat from materials. Which of the following pictures should be placed on the side of heat being removed from the material?
a frozen popsicle
baked cupcakes
steam from a pot
melted candy bar
Answer: It's kind of a subjective question by saying Which of the following pictures should be placed on the side of heat being removed from the material?
Explanation: I'm not entirely sure about this but I would think that it would be baked cupcakes because they had to undergo heat to become "baked", so they are the result of heat.

Answer Should Be given With Headings!
Explanation:
that’s hard
Answer:
Rutherford conducted an experiment (α-particles scattering) in order to find the arrangement of electrons and protons in an atom. This experiment led to the discovery of nucleus in an atom.
Explanation:
Rutherford bombarded a thin gold foil (about 0.00004 cm thick) with alpha particles in an evacuated chamber. These particles got scattered and were allowed to to strike on a circular zinc sulphide coated screen. He observed a flash of light on the screen where the alpha particles struck. From this experiment, he made the following conclusions.
Observation 1: Most alpha particles (α-particles) pass straight through the gold foil without any deflection from their original paths.
Conclusion: There is a lot of empty space in the atom.
Observation 2: A few alpha particles were deflected, at small angles and a few at large angles.
Conclusion: There is a small positively charged object at the centre of the atom. He said this because as alpha rays are positively charged it can pass through only negatively charged particles and get deflected by the same charge. He concluded that the small positively charged object present within the atom is called the nucleus.
Observation 3: Very few alpha particles completely rebounded on hitting the gold foil.
Conclusion: The nucleus is dense and hard. It is located at the centre of the atom.

Explanation:
The figure depicts a vernier caliper readings
a.) The main scale reading is 10.2 cm
The reading before the vernier scale
b.) Division 7 = 0.07
the point where the main scale and vernier scale meet
c.) The observed readings is
10.2 + 0.07 = 10.27 cm
d.) If the instrument has a positive zero error of 4 division
correct reading = 10.27 + 0.04 = 10.31cm
e.) If the instrument has a negative zero error of 3 division
correct reading = 10.27 - 0.03 = 10.24cm

The work input = _____.
F i ÷ d i
F o ÷ d o
F o × d o
F i × d i
The work input = Fi × di
How to solve for work input?To solve for work input, you need to know the force acting on an object and the distance it moves in the direction of the force. Work input is defined as the product of force and distance, given by the formula:
Work Input = Force × Distance × cosθ
Where θ is the angle between the force vector and the direction of motion. If the force is applied in the direction of motion, then θ = 0 and cosθ = 1, so the formula simplifies to:
Work Input = Force × Distance
For example, if you are pushing a box with a force of 50 newtons over a distance of 10 meters, the work input would be:
Work Input = 50 N × 10 m × cos(0°) = 500 Joules

(g=10 m/s2)
PLEASEEE FASTTTTT PLEASEEE
Answer:
potential energy=mgh
=50×10×20
=10000 J
Answer:
\(\huge\boxed{\sf P.E. = 10 kJ}\)
Explanation:
Given Data:
Mass = m = 50 kg
Height = h = 20 m
Acceleration due to gravity = g = 10 m/s²
Required:
Potential Energy = P.E. = ?
Formula:
P.E. = mgh
Solution:
P.E. = (50)(20)(10)
P.E. = 10,000 Joules
P.E. = 10 * 10³ Joules (10³ = Kilo)
P.E. = 10 kJ

Sometimes people refer to Mars as the Red Planet. Because of the rusty iron in the earth, it is red. Mars features weather, polar ice caps, canyons, volcanoes, and seasons just like Earth. Its atmosphere, which is composed of carbon dioxide, nitrogen, and argon, is extremely thin. These define Mars' characteristics.
These are some of the characteristics of the moon, which is the only natural satellite of Earth and the nearest huge celestial body. It is a spherical rocky body that revolves around Earth in a somewhat eccentric orbit at a mean distance of around 384,000 km (238,600 miles), perhaps with a tiny metallic core. It has a 1,738 km (1,080 miles) equatorial radius.
What is planet ?A celestial body inside the Solar System that meets the following criteria is referred to as a "planet": (a) it must be in orbit around the Sun; (b) it must have enough mass to overcome rigid body forces and take on a hydrostatic equilibrium form that is almost circular; and (c) it must have cleared the area in and around its orbit.
