B. protons are negative, neutrons are positive
C. protons are positive, electrons are negative
Answer:
C
Explanation:
protons are positive neutrons are neutral and electrons are negative
In an electrically charged particles protons are positive and electrons are negative.
Neutron has a positive electrical charge?The charge on neutron is zero(no charge). The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another and so atoms are neutral. Protons have positive or negative?A proton carries a positive charge and an electron carries a negative charge.so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain.Learn more about electrical charge here: http://brainly.brainly.com/question/1487561

Give an example of central heating and of local heating.
Answer:
A central heating system provides warmth to the whole interior of a building from one point to ... Institutional heating systems (office buildings or schools, for example) can use low-grade, inexpensive
An alternative to district heating would be to build a small district heating plant together with your neighbours, which is known as local heating or joint heating. ... The local heating system also includes a network of pipes and a common boiler plant that delivers heat through the pipework to the single-family houses.

Which of the following would cause an error in DNA replication?
A. DNA polymerase pairing A with G
B. DNA ligase connecting chunks of DNA
C. Helicase making a replication fork
D. DNA polymerase checking the DNA
Answer:
A. DNA polymerase pairing A with G
Explanation:
Adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).
DNA polymerase pairing A with G would cause an error in DNA replication. The correct option is A.
An error in DNA replication occurs when an incorrect nucleotide is inserted during the replication process.
DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.
It ensures the accuracy of replication by matching each nucleotide with its complementary partner (A with T and G with C).
If DNA polymerase pairs A with G instead of A with T, it results in a mismatched base pair.
This is considered an error in DNA replication since it introduces a mutation in the newly synthesized DNA strand.
The fidelity of DNA replication relies on the correct base pairing and proofreading mechanisms of DNA polymerase to minimize errors and maintain the integrity of the genetic information.
Thus, the correct option is A.

Explanation:
In shorthorn cattle, color shows incomplete dominance. A red cow has the genotype RR. A white cow
has the genotype ww. Heterozygous cattle are called Roan (red and white spotted) (RW).
1. Cross a red bull with a roan cow. Show the Punnett Square:
% Red Cow
% Roan Cow
% White Cow
Answer:
red cow would be 50% and the same for a roan cow
Cross a Red Bull with a roan cow. The Punnett Square are
% Red Cow = 25% red
% Roan Cow = 50% roan
% White Cow = 25% white
What is a Punnett square?A Punnett square is a square with a block that is used to see and describe the offspring of the next generation. It contains both genotypes, dominant and recessive, and then there is a crossing over.
Given that, the red cow has genotype RR
A white cow has the genotype ww.
Heterozygous cattle are called Roan (red and white spotted) (RW).
When RR (red) is crossed with WW (white), it results in a roan color.
RR (red) x WW (white) = RW (roan)
Two roan individuals are then mated.
RW x RW
RR RW RW WW
Offspring
1/4 RR - Red
1/2 RW - Roan
1/4 WW - White
Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.

How do you think Nucleic Acids and Proteins work together in the body? Why are they both important to humans?
Explanation:
protein is the element responsible for building up of cells and the nucleic acid is embedded in the cell, so protein builds the whole cell including the nucleic acids.. the nucleic acid is also packed by histones which is a proteinous structure. both are important because, in the cell all organelles require protein for their growth and likewise the encoding of the genetic information carrier

_____ is a force caused by air that slows objects down
Answer:
Drag
Explanation:
Drag is a force caused by air that slows objects down
Friction is a major force that slows the object down, air resistance is a type of frictional force.
What is air resistance?Air resistance is a kind of frictional force that slows down an object from moving in a particular direction.
During the movement an object has a particular speed for movement, speed depends on how friction works, more friction slows the speed of an object a low friction allows the object to at a particular speed.
Air is a mixture of gases and particles in the atmosphere, these particles create a force during the movement of an object in the air, and these forces decide the actual speed of object movement.
Therefore air resistance is a force that slows the object.

Which of the following stages of photosynthesis involves carbon fixation, reduction reactions, and the ribulose 1,5-bisphosphate regeneration?
photoreduction
light-independent reaction
light-dependent reaction
first stage photosynthesis
Answer:
light-independent reaction
Explanation:
Photosynthesis, which is a unique metabolic process where plants synthesize their food (glucose) in the presence of sunlight, occurs in two stages namely: light dependent stage and light-independent stage.
The light independent stage is also known as dark stage because it does not require light to occur. It occurs in the stroma of the chloroplast where ATP and NADPH are used to fix carbon into the production of glucose. This stage involves three major processes:
- Carbon fixation of CO2
- Reduction reactions of G3P
- Regeneration of ribulose 1,5-bisphosphate (RUBP).
