Which of the following is a chemical reaction?
A. Water freezes.
B. Sugar dissolves in water.
C. Salt and pepper are mixed in a dish.
D. Iron rusts.
Answer:
i think it is d
Explanation:
sorry if wrong
Answer: D. Iron rusts
Explanation: Rust is made from different chemicals in the air that come in contact with said metal. That could be acidic rain for example. Water freezing is only changing temperature. Sugar dissolving is breaking down molecules. Salt and pepper mixed in a dish is a physical change (also that's just plain evil to some people but that isn't the point). Your answer will be D. Iron rusts.

Increasing the number of coils in a solenoid or an electromagnet results in a ___
magnetic field.
Answer: Stronger Magnetic Field
Explanation:
The magnetic field in a solenoid is given by
[tex]B=\mu nI[/tex]
where B=magnetic field
[tex]\mu=[/tex]Permeability
n=no of turns per unit length
I=Current through solenoid
When No of turns increases, it increases the strength of the magnetic field.

How do cells support the evolution theory?
Answer:
Hope this helps!
Explanation:
The endosymbiotic theory explains how eukaryotic cells evolved. The large and small cells formed a symbiotic relationship in which both cells benefited. Some of the small cells were able to break down the large cell’s wastes for energy. They supplied energy not only to themselves but also to the large cell.
Color blindness is a X-linked recessive trait. A couple want to predict whether it would be possible for their child to be color blind. The female is an unaffected carrier and the male is red/green color blind. What percentage of offspring would be color blind?
Answer: There is a probability (n.b. NOT certainty) that half of all offspring will be colour blind.
Explanation: The female is XX and as an unaffected carrier we can assign genotype Cc where c is the recessive allele.
The male is XY and colour blind, so genotype cY
Male offspring can be cY or CY so p|colourblind = 50%
Female offspring can be Cc or cc so, again p= 50%
If there is also equal probability of sex of the offspring, there is an overall probability that half the offspring will be colour blind

During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a △G of -20 kcal/mol. If you double the amount of enzyme in the reaction, what will be the △G for the new reaction?
A. +20 kcal/mol
B. -40 kcal/mol
C. -20 kcal/mol
D. -10 kcal/mol
Answer:
Option-C
Explanation:
Delta G (△G) refers to the overall energy released during a chemical reaction when equilibrium is reached i.e the rate of conversion of product into the substrate is equal to the rate of conversion of substrate into product. Thus, △G accounts for the equilibrium of the reaction.
In the given question, it has been mentioned that △G of a reaction is -20 kcal/mol then how will it change if the amount of enzyme is doubled.
The △G is not affected by the enzyme concentration as the presence of enzyme affects the G (Gibbs free energy) and activation energy.
Therefore, △G will remain the same even if the amount of enzyme is doubled i.e -20 kcal/mol will be the correct value.
Thus, Option-C is the correct answer.

Water that falls onto land surfaces is either soaked into the ground or flows downhill into a body of water. The water that soaks into the ground is called groundwater.
Soil and rock that allow this water to pass through them are called ________.
A. aquifers
B. compacted
C. permeable
D. runoff
The capacity of a rock or other substance to let the passage of water is known as permeability, hence option c is correct.
What is groundwater?Groundwater may readily flow through permeable materials because the pore space is linked throughout the rock or sediment. Mud and clay are examples of materials with great porosity yet very limited permeability.
An aquifer is a water-bearing rock that easily transfers water to wells and springs, the aquifers may be dug into and water pumped out.
Therefore, water that falls onto land surfaces flows into water bodies or it may be soaked in the ground, this water flows through the soil and rock which are permeable, hence option c is correct.

Calculate the mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2
Answer:
40kg
Explanation:
F=M*A
M=F\A
M=400\10
M=40kg
The mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2 is 40 kg.
What is acceleration due to gravity?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 direction, strength, or magnitude match a plumb bob.
According to Newton's second law, an object's acceleration is inversely proportional to its mass and directly connected to the net force. An object's acceleration is determined by two factors: force and mass.
We know that,
F = m x g
m = f/g
Where,
F = force
m = mass
g = acceleration due to gravity
Given that,
F = 400N.
g = [tex]10m/s^2[/tex]
So,
m = 400/10
m = 40 kg.
Thus, the mass is 40 kg.

which describes a difference between a positive and negative feedback loop?
a. the output of a system stimulates another cycle of the system only in a positive feedback loop.
b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.
c. the output of a system maintains conditions around a set point only in a positive feedback loop.
d. the output of a system signals the system to disregard the stimulus only in a negative feedback loop
Answer: b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.
Explanation:
In the negative feedback loop, the feedback reduces the excessive response of the stimulus for example regulation of body temperature, and control of blood glucose level. In the positive feedback loop, the response of a stimulus is intensified. Example, positive feedback is the childbirth and blood clotting. According to the negative feedback loop the output of the system keeps the internal body environment constant with respect to the changes in the external environment hence, maintains the homeostasis.
Answer:
b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.

Answer:
Catastrophism, doctrine that explains the differences in fossil forms encountered in successive stratigraphic levels as being the product of repeated cataclysmic occurrences and repeated new creations. ... This doctrine generally is associated with the great French naturalist Baron Georges Cuvier
The mechanism of catastrophism directly explains the process of fossil formation. It described the natural history that has been punctuated by catastrophic events that altered the way life developed and rocks were deposited.
What is Catastrophism?Catastrophism may be defined as a type of geologic doctrine that significant changes in the earth's crust that have in the past been brought about suddenly by a series of events like mass extinction.
