Which statement accurately describes radioactive dating?
A.Geologists use only one type of radioactive dating.
B.Geologists compare parent and daughter elements to determine rock type.
C.Geologists will measure how stable multiple parent elements can decay into multiple daughter elements.
D.Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.
Answer:
D. Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.
Explanation:
Radioactive dating is the method in which radioactive isotopes are employed to evaluate the age of rocks and ores. There are many complex radioisotopes utilized for radioactive dating is like Potassium, Uranium, and Carbon. Radioactive dating operates on the system that a radioactive isotope can fade into the constant daughter nuclei at a steady rate. Geologist commonly uses the system for half life. Half-life is the time needed for half of the radioactive element to decline. This is fixed for a selective element.

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 does the structure of DNA explain chargaff's rule?
Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine
Chargaff's Rule explains that in the natural DNA, the total number of guanine equals to the number of cytosine and the total number of adenine equals to the number of thymine. This tells about the base pair composition of DNA molecule.
What is Chargaff's rule?Chargaff's rule states that in the DNA molecule of any species or organism, the total amount of guanine residues should be equal to the amount of cytosine residues and the amount of adenine residues should be equal to the amount of thymine residues. A stoichiometric ratio of 1:1 of purine and pyrimidine bases i.e., A + G = T + C should be fulfilled.
Chargaff's rule describes the ratio of the various nitrogenous bases present in the DNA molecule. It aids in the determination of the structure and composition of DNA in living organisms. It is constant for a species.

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

What are the functions of epinephrine?
Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions. It appears as a white microcrystalline granule.
Epinephrine injection is used for emergency treatment of severe allergic reactions (including anaphylaxis) to insect bites or stings, medicines, foods, or other substances.
Through its action on alpha-1 receptors, epinephrine induces increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction.

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.

Which best explains the role of plants in the nitrogen cycle?
Answer:
Assimilation
Explanation:
This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. ... When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle.

Answer:
Radiometric dating. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. ...

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.
