Explanation:
Y red ballonls and m green ballons were divided evenly amoung three kids. How many ballons did each kid get
Answer:
Each kids will get Y red balloons + M green ballons ÷ 3.
Explanation:
This is because Y red balloons and green red balloons are the total number of balloons present.
The total number of ballons are Y red+M green ballons.
The total number of kids are 3.
Therefore each kids with get the addition of the ballons divided by 3.
Therefore, Y red ballons + M green ballons ÷ 3.

Explain why tongue rolling ability is a discontinuous variation
Since tongue rolling ability is determined by a single gene with two separate alleles—the dominant allele, which codes for tongue rolling ability, and the recessive allele, which codes for tongue rolling incapacity—tongue rolling ability is a discontinuous variation.
What is Tongue rolling ability?The hereditary characteristic known as tongue rolling ability controls whether or not a person can roll their tongue into a tube shape. This characteristic is frequently used as an illustration of a straightforward hereditary trait with discontinuous variation since there are only two possible outcomes: either a person rolls their tongue or they do not.
Either a person has the recessive allele, which prevents them from rolling their tongue, or they have the dominant allele, which allows them to roll their tongue. There is no intermediate or in-between trait, and the presence or absence of the dominant allele is a distinct, plainly observable phenotype.
Therefore, the capacity for tongue rolling is an illustration of a discontinuous variation.

Researchers used DNA sequencing techniques to find similarities of Hox genes in roundworms, arthropods, mollusks, echinoderms, cephalochordates, and vertebrates. What did they find out about these genes? Select all that apply. A. Hox genes provide information about evolutionary relationships. B. Similarities among Hox genes suggest that they all arose from a single ancestral gene that duplicated many times. C. Hox genes are regulatory genes that determine body plans of animals. D. Only some animals that have been tested have Hox genes, suggesting that Hox genes have no function and only evolved recently.
Answer:
(B) Similarities among Hox genes suggest that they all arose from a single ancestral gene that duplicated many times.
Explanation:
Hox genes are arranged in clusters and their order on the chromosome is the same as the order in which they are expressed along the body during development.

Explain how errors in DNA replication and environmental factors cause genétic variation
DNA replication is a truly amazing biological phenomenon. Consider the countless number of times that your cells divide to make you who you are—not just during development, but even now, as a fully mature adult. Then consider that every time a human cell divides and its DNA replicates, it has to copy and transmit the same sequence of 3 billion nucleotides to its daughter cells. Finally, consider the fact that in life (literally), nothing is perfect. While most DNA replicates with fairly high fidelity, mistakes do happen, with polymerase enzymes sometimes inserting the wrong nucleotide or too many or too few nucleotides into a sequence. Fortunately, most of these mistakes are fixed through various DNA repair processes. Repair enzymes recognize structural imperfections between improperly paired nucleotides, cutting out the wrong ones and putting the right ones in their place. But some replication errors make it past these mechanisms, thus becoming permanent mutations. These altered nucleotide sequences can then be passed down from one cellular generation to the next, and if they occur in cells that give rise to gametes, they can even be transmitted to subsequent organismal generations. Moreover, when the genes for the DNA repair enzymes themselves become mutated, mistakes begin accumulating at a much higher rate. In eukaryotes, such mutations can lead to cancer.

17. Identify How would the
shuttle's motion change if
there were no gravitational
force between it and Earth?
Answer:
Gravity is one of those things we take completely for granted. And there are two things about it that we take for granted: the fact that it is always there, and the fact that it never changes. If the Earth's gravity were ever to change significantly, it would have a huge effect on nearly everything because so many things are designed around the current state of gravity. Before looking at changes in gravity, however, it is helpful to first understand what gravity is. Gravity is an attractive force between any two atoms. Let's say you take two golf balls and place them on a table. There will be an incredibly slight gravitational attraction between the atoms in those two golf balls. If you use two massive pieces of lead and some amazingly precise instruments, you can actually measure an infinitesimal attraction between them. It is only when you get a gigantic number of atoms together, as in the case of the planet Earth, that the force of gravitational attraction is significant. The reason why gravity on Earth never changes is that the mass of the Earth never changes. The only way to suddenly change the gravity on Earth would be to change the mass of the planet. A change in mass great enough to result in a change in gravity isn't going to happen anytime soon.
Explanation:
But let's ignore the physics and imagine that, one day, the planet's gravity turned off, and suddenly there was no force of gravity on planet Earth. This would turn out to be a pretty bad day. We depend on gravity to hold so many things down -- cars, people, furniture, pencils and papers on your desk, and so on. Everything not stuck in place would suddenly have no reason to stay down, it would start floating. But it's not just furniture and the like that would start to float. Two of the more important things held on the ground by gravity are the atmosphere and the water in the oceans, lakes, and rivers. Without gravity, the air in the atmosphere has no reason to hang around, and it would immediately leap into space. This is the problem the moon has -- the moon doesn't have enough gravity to keep an atmosphere around it, so it's in a near-vacuum. Without an atmosphere, any living thing would die immediately and anything liquid would boil away into space. In other words, no one would last long if the planet didn't have gravity. If gravity were to suddenly double, It would be almost as bad, because everything would be twice as heavy. There would be big problems with anything structural. Houses, bridges, skyscrapers, table legs, support columns, and so on are all sized for normal gravity. Most structures would collapse fairly quickly if you doubled the load on them. Trees and plants would have problems. Power lines would have problems. The air pressure would double and that would have a big effect on the weather. What this answer shows you is just how integral gravity is to our world. We can’t live without it, and we can't afford to have it change. It is one of the true constants in our lives!

Jonathan consumes five 12 ounce beers throughout the day. How many additional
calories has he added to his diet?
710 kcals
630 kcals
490 kcals
280 kcals
The given options must be in the calories in approximate value.
Answer:
The best answer is - 710 calories approximately.
Explanation:
One ounce of the beer provides 12 calories and as it is given that Jonathan drinks five 12 ounce beers throughout the day then,
12 ounce = 12 × 12 × 5
= 144 × 5
= 720 calories
Thus, it is found out that he has added 710 calories approximately to his diet additional.

New alleles can arise in both asexual and sexual reproduction.
Which of the following statements is TRUE based on the disadvantages of sexual and asexual reproduction.
A- Gametogenesis is the only source of genetic variation for sexual reproduction
B- This answer choice is wrong
C- Mutations are the only source of genetic variation for asexual reproduction
D- Meiosis is the only source of genetic variation for sexual reproduction
Answer:
C - Mutations are the only source of genetic variation for asexual reproduction
Mutations are the only source of genetic variation for asexual reproduction.
What is mutation?
A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.
A mutation is never so advantageous in real life that it makes someone a superhero or does anything strange like give them wings. There are numerous explanations for why mutations typically don't have significant effects.
Therefore, Mutations are the only source of genetic variation for asexual reproduction.
