which of the following statements describes a proton of an atom?
a. has a negative charge and is located in the nucleus
b. has a positive charge and is located in outer energy levels
c. has no charge and is located in the nucleus
d. has a positive charge and is located in the nucleus
Answer:
d. Has a positive charge and is located in the nucleus
Memory technique:
Think of the "p" and proton and the "p" in positive.
Think of the "neu" in neutron and "neu" in neutral.
Think about electrons and electricity. Touching something "elec"tric would hurt, or give you negative feelings.
Electrons revolve around the cell while protons and neutrons are a part of the nucleus because negative and positive things would not get along.
That's all I have! I hope this helps with your studying. Happy learning, friend! :)

Where do action potentials end?
The action potential terminates at the axon terminal or terminal boutons.
What do you mean by Action potential?Action potential may be defined as reversal activity in electrical potential across a plasma membrane that occurs when a cell has been activated by a stimulus.
The action potential is generated at the region of the axon hillock and propagates along the axon. Finally, they terminated at the region of the axon terminal.
Therefore, the action potential terminates at the axon terminal or terminal boutons.

is protein a living cell or a virus
Answer:
Neither.
Explanation:
Proteins are molecules composed of carbon, hydrogen, oxygen, and most importantly one or more chains of amino acids. They are vital to living cells and are required in the process of making, repairing, and composing functioning tissues as well as helping them function.

why are Some substances allowed to cross the cell membrane while other substances are not?
Answer:
membranes are semipermeable so only let certain materials in and out; if there are carrier or channel proteins, then passive transport can occur otherwise active transport is required which requires energy.

5. What happens to the force between the two spheres of the same
mass when the distance the mass Spheres is halved?
Answer:
The force of gravity on each object increases with the square of the inverse distance as they fall together, and hence so does the acceleration. For example, if the distance is halved, the force and acceleration are quadrupled.

Explanation:
In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. We’ll use the symbol Bb for the beard allele and B+ for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant over the allele for a white coat (w). Give the phenotypes and their expected proportions for the cross between B+Bb Ww male × B+Bb Ww female.
Which of the following is not an option phenotype and proportion from this cross?
a. 9/16 bearded, black female
b. 3/16 bearded, black female
c. 1/16 beardless, white male
d. 3/16 bearded, white male
e. 1/16 bearded, white female
Autosomal alleles are the genetic inheritance by the variants that are passed from parent to child. From the cross between B+Bb Ww × B+Bb Ww, 3/16 bearded, black coat, and 1/16 bearded, white is not a correct phenotype. Thus, options b and e are correct.
What is a dihybrid cross?A dihybrid cross has been defined as the experimental mating of an organism that has two variable traits located at various genes. The traits can be autosomal dominant and autosomal recessive.
Given,
Autosomal dominant = Bb (beard), W (black coat)
Autosomal recessive = B+ (beardless ), w (white coat)
Parent = B+Bb Ww male and B+Bb Ww female
The cross between the parent is attached to the image below.
From the cross, it can be said that:
9/16 bearded, black coat1/16 beardless, white coat3/16 beardless, black coat3/16 bearded, white coatFrom the cross, 3/16 bearded, black females and 1/16 bearded, white females are not the phenotypes.
Therefore, options b and e. 3/16 bearded, black females and 1/16 bearded, white females are not the phenotypes.

Both will be equal to one another.
Neither has an affect on the population.
The death rate will be larger.
Answer:
it will compare that neither has an affect on the population and it will also compare that both will be equal to one another.Hope this helps let me know if its wrong or not have a good day.
Explanation:
It will compare that neither has an affect on the population and it will also compare that both will be equal to one another.
What is population?The term "population" refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area.
Growth rates are the population changes that occur each year as a result of births, deaths, and net migration.
The total population also includes national military forces deployed overseas, merchant mariners at sea, diplomatic staff based abroad, civilian foreign nationals residing in the nation, and internally displaced people residing in the nation. Demographic tools like population predictions are frequently used.
Therefore, It will compare that neither has an affect on the population and it will also compare that both will be equal to one another.

compare the hygiene allergies and asthma?
Answer:
According to the “hygiene hypothesis,” the problem with extremely clean environments is that they fail to provide the necessary exposure to germs required to “educate” the immune system so it can learn to launch its defense responses to infectious organisms. Instead, its defense responses end up being so inadequate that they actually contribute to the development of asthma.

A S'AGGTCAGGT 3
B
S'ACCUGAGGU 3
C 5'TGGACTGGA 3
D 5' TCCAGTCCA 3
The correct complementary DNA sequence of 3'AGGTCAGGT 5 is - D. 5' TCCAGTCCA 3'
DNA is made of two strands of DNA strands coiled together and form a ladder-like shape. DNA molecules have four nucleotide bases that joined both strands together that are Adenine (A), Guanine (G), Thymine (T), and Cytosine(C).
Each nitrogenous base has its own complementary base in a double-helical structure.The A is complimentary T and G will have CThe complementary strand is always present in an antiparallel directionIf one strand is 3' to 5' then the complementary strand would be 5' to 3'So, in the given sequence: 3'AGGTCAGGT 5
Complementary sequence: 5' TCCAGTCCA 3
