Scientists were examining the maize genome. They had two specimens: one control and one specimen that had undergone mutagenesis. They saw that the mutant specimen underwent a knockout caused by a nucleotide exchange in the DNA. When they compared gene sequences, they saw same number of nucleotide bases. Which type of mutation had most likely occurred? deletion insertion inversion substitution

Answers

Answer 1

Answer:

substitution

Explanation:

A substitution is a point mutation where a nucleotide base (either adenine, guanine, thymine or cytosine) is replaced by a different base pair. In contrast to insertions or deletions, substitutions don't change the number of bases in the DNA sequence. Moreover, inversions are large genetic rearrangements where the genetic sequence is reversed. A substitution may have different effects: change a codon to another (changing the protein sequence when codons are translated into amino acids), produce a stop codon, cause synonymous mutations (i.e., neutral mutations that don't alter the amino acid sequence due to the degeneracy of the genetic code), etc.

For the third one (bottom left one), it is aA

For the fourth one (bottom right one), it is aa

This one above ^^^ is the top line of the punnet square (the small line)

A = free-hanging earlobes

a = attached earlobes

For the first box (top left one), it is free-hanging earlobes (both "A"s are dominants, and the dominant is greater than the recessive one).

For the second box (top right one), it is free-hanging earlobes (there is at least one dominant A so it will be greater than the other "a" although there is a chance for it to be an attached earlobe, but in this case, it isn't)

For the third one (bottom left one), it is free-hanging earlobes (again, there is at least one dominant A so it will be greater than the other "a" even though, there is a chance for it to be an attached earlobe, but in this case, it isn't)

For the fourth one (bottom right one), it is attached earlobes (both "a"s are recessive, there is not one dominant "a" which means that it will be an attached earlobe".

This one above is ^^^ is for the second line in the punnet square (the longest line) P.S you dont have to write the explanation you can just write if it's an attached earlobe or a free-hanging one

The ratio will be 75% to 25%. The 75% will be the offsprings inheriting the free-hanging earlobes, and the 25% will be the offsprings inheriting the attached earlobe. It is most likely that the offspring will inherit the trait for free-hanging earlobe since it is the dominant allele there is.

In each drawing, there are lines between each atom and each molecule. What do you think the lines between atoms represent? The lines between molecules?

Answers

Answer:

Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds. A compound is a distinct group of atoms held together by chemical bonds. Just as the structure of the atom is held together by the electrostatic attraction between the positively charged nucleus and the negatively charged electrons surrounding it, the stability within chemical bonds is also due to electrostatic attractions. To illustrate further, consider the two major types of chemical bonds: covalent bonds and ionic bonds. In covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail.

Explanation:

Answer:Each straight line segment represents a bond, the ends and intersections of the lines are carbon atoms, and the correct number of hydrogens is calculated from the tetravalency of carbon. Non-bonding valence shell electrons are omitted in these formulas.Each line represents a single covalent bond (two shared electrons), so double lines represent a double covalent bond (four shared electrons). Covalent bonds are usually found in atoms that have at least two, and usually less than seven, electrons in their outermost energy shell, but this is NOT a hard and fast rule.

direction of gravitational  pull of the Sun on the planet

Explanation:

A planet orbiting or revolving around the sun due to gravitational  force of the Sun on the planet which attracts the planet and compel the planets to move in a circular path. If this force of gravity is not applied on the planets, the planets will move in a straight line instead of circular direction so gravitational  pull of the Sun on the planet is very necessary for moving planets in a circular path.

Answers

Momentum is the quantity of motion of a moving body. It is expressed mathematically as p = m * v and has units of kg m/s.

The quantities that significantly define the momentum are known as Mass and velocity. Thus, the correct option for this question is B.

What is Momentum?

Momentum may be defined as a type of physical property that remarkably describes the motion of any moving object. It is a type of vector quantity as it possesses both magnitude and direction. It may be generally characterized as the product of mass and velocity.

According to the context of this question, the momentum of any object may be calculated as follows:

Momentum, P = M × V, where M = mass of an object and v = velocity of an object.

The unit of momentum is Newton-second (N-s) or kg m/s.

Therefore, the quantities that significantly define the momentum are known as Mass and velocity. Thus, the correct option for this question is B.

What is one trait that could be used to separate these albatrosses into two groups of two birds each?

Answers

The correct answer to this open question is the following.

You did not attach the options for this question. However, we can answer the following.

Although there are no pictures of the Albatross, we can say that one trait that could be used to separate these albatrosses into two groups of two birds each is "a large group of solid black feathers vs. black and grey patterned feathers."

If someone ask you what are the birds with larger wings, you probably would answer "the Bald Eagle," Or any other kind of eagle. Maybe the Southamerican Condor. And those answers are incorrect. The correct answer: the Albatross.

This is a carnivore bird which wingspan varies from 6.5 to 11 to 11 feet, Its average weight is 22 pounds. These impressive birds can use their long wings to fly over the seas for miles and miles, without taking a rest.

THE WORLD WITH A THOUSAND MOONSCHAPTER 1: Thrill CruiseBy Edmond HamiltonLance Kenniston felt the cold realization of failure as he came out of the building into the sharp chill of the Martian night. He stood for a moment, his lean, drawn face haggard in the light of the two hurtling moons.He looked hopelessly across the dark spaceport. It was a large one, for this ancient town of Syrtis was the main port of Mars. The forked light of the flying moons showed many ships docked on the tarmaca big liner, several freighters, a small, shining cruiser and other small craft. And for lack of one of those ships, his hopes were ruined!A squat, brawny figure in shapeless space-jacket came to Kenniston's side. It was Holk Or, the Jovian who had been waiting for him."What luck?" asked the Jovian in a rumbling whisper."It's hopeless," Kenniston answered heavily. "There isn't a small cruiser to be had at any price. The meteor-miners buy up all small ships here.""The devil!" muttered Holk Or, dismayed. "What are we going to do? Go on to Earth and get a cruiser there?""We can't do that," Kenniston answered. "You know we've got to get back to that asteroid within two weeks. We've got to get a ship here."Desperation made Kenniston's voice taut. His lean, hard face was bleak with knowledge of disastrous failure.The big Jovian scratched his head. In the shifting moonlight his battered green face expressed ignorant perplexity as he stared across the busy spaceport."That shiny little cruiser there would be just the thing," Holk Or muttered, looking at the gleaming, torpedo-shaped craft nearby. "It would hold all the stuff we've got to take; and with robot controls we two could run it.""We haven't a chance to get that craft," Kenniston told him. "I found out that it's under charter to a bunch of rich Earth youngsters who came out here in it for a pleasure cruise. A girl named Loring, heiress to Loring Radium, is the head of the party."The Jovian swore. "Just the ship we need, and a lot of spoiled kids are using it for thrill-hunting!"Kenniston had an idea. "It might be," he said slowly, "that they're tired of the cruise by this time and would sell us the craft. I think I'll go up to the Terra Hotel and see this Loring girl.""Sure, let's try it anyway," Holk Or agreed.With the Jovian clumping along beside him, Kenniston made his way from the spaceport across the ancient Martian city.Read the following line from the text:The forked light of the flying moons showed many ships docked on the tarmac.Which words remind the reader that this story is set in space?
