Summarize: How are the processes of natural selection and artificial selection similar? How are they
different?

Answers

They both result in a particular allele rising in frequency in the population over time. They are different in that natural selection will only cause an allele to rise in frequency if that allele provides individuals with an increased relative fitness. Artificial selection can be used to cause a rise in frequency of alleles which do not provide individuals with increased relative fitness.

18. Brayden is trying to figure out how petal shape is determined in two different roses. In the pink
rose, the copies of the gene are the same as each other. In the yellow rose, the copies of the gene are
different from each other. How does this affect how many types of proteins there are in each petal
cell?
a
The pink rose has one type of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
b
The pink rose has one type of protein for the petal shape feature. The yellow rose has one
type of protein for the petal shape feature.
с
The pink rose has two types of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
d
It is impossible to say anything about proteins from the given information.

Answers

Answer:

c

Explanation:

they would have diffrent gene versions and protines to get their colors

In the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.

What is the petal shape dependent on?

Generally, the characters are dependent on the genes that are present in the DNA; either the gene variants, such as the alleles, show pure dominance or they combine to produce the effect, and here the pink rose petal has the same alleles so they will express the single protein while the yellow has different alleles so it has the chance of the two proteins.

Hence, in the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.

16. The substances that are reabsorbed did not diffuse (move) from the nephron bowl into the
renal vein cup. You needed to use lots of energy to make reabsorption happen. Which
process do you think the kidney uses to transport these substances from the nephron to the
renal vein-active transport or diffusion (passive transport)? Explain your answer.

Answers

Answer:

Active transport.

Explanation:

The kidney uses active transport  to move these substances from the nephron to the  renal vein because these substances did not moves from the nephron bowl to the renal vein through simple diffusion so for this purpose active transport is used in which energy is spent in order to move the substances from one region to another so we can say that kidney must use active transport to move reabsorbed substances from the nephron to the  renal vein.

Select one:

A. Plants store genetic information in the nucleus of their cells

B. Plants are motile primary consumers

C. Plants are multicelular

D. Plants are autotrophic

Answers

Answer:

D. Plants are autotrophic

Explanation:

Both plants and animals are eukaryotic, meaning they contain a nucleus with genetic information, so that crosses out A. I don't know what motile primary consumers are. Assuming, they're primary consumers, primary consumers are those that eat producers, so in this case, this would elminate B. Both plants and animals are multicellular. Plants ARE autotrophic, meaning they produce their own food. Animals, however, have to get their own food, either by hunting or scavaging.

The following table describes some biotechnological processes.

Biotechnological Processes
Process Description
1 Producing offspring that have identical DNA as one parent
2 Crossing a high-yielding fruit variety with a high-vitamin variety
Which biotechnological processes are described in the table? (3 points)

a
Both processes describe cloning.

b
Both processes describe genetic engineering.

c
Process 1 describes cloning and process 2 describes artificial selection.

d
Process 1 describes artificial selection and process 2 describes cloning.

Answers

Answer:

c . Process 1 describes cloning and process 2 describes artificial selection.

Explanation:

Process 1 describes cloning because offspring is produced that are similar to its parent and we know that in cloning, the offspring is identical to their parents while on the other hand, process 2 describes artificial selection because crossing between a high-yielding fruit variety with a high-vitamin variety is done which is only possible through the intervention of humans.

EOC Biology STAAR Test Prep
In humans blood type is determined by the A, B, and O alleles. The A and B alleles are codiminant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes.
O only
A or B only
A, B or O only
A, B, AB, or O
Please explain, also this is not a test its a test PREP

Answers

Answer:

D. A, B, AB, or O

Explanation:

We can start by visualizing all the possible genotypes of the offspring by drawing a Punnett square, which is a visual representation of the different possible combinations of alleles:

Individual 1 = AO, Individual 2 = BO

     A   O

B  AB  BO

O  AO  OO

Here we can see that there are 4 possible genotypes: AB, BO, AO and OO based on the alleles of the parents. Now we can match the genotypes to phenotypes to answer the question:

A and B are codominant, meaning that both will be expressed equally if both are present. Therefore the genotype AB will result in an AB phenotype.

Next, since A and B are both dominant over O, they are the alleles that will be expressed in the phenotype if paired with an O. This means that the genotype AO will result in an A phenotype, and likewise, genotype BO will result in phenotype B.

Finally in the genotype OO, although O is a recessive allele, there are no dominant alleles here to mask them, therefore O is expressed in the phenotype.

Hence, from the genotypes AO and BO, the possible offspring genotypes are AB, BO, AO and OO, translating to the possible phenotypes: A, B, AB or O.

Heron was large and slow, with a long, gangly neck and big, floppy wings. Hummingbird was tiny and swift, with wings that moved so quickly that they buzzed and a slender beak as sleek as a needle.Heron and Hummingbird both loved to eat fish from the river. Every morning, Heron would fish to her heart's content, eating until her stomach was so round and heavy that she had to waddle back to shore. Every afternoon, Hummingbird would fish and feast until he was so heavy that his tiny, buzzing wings could no longer keep him in the air. Heron and Hummingbird thought they were the luckiest birds in the world.One afternoon, Hummingbird did not catch as many fish as usual. He fished and he fished, but his line came up empty more times than it ever had before. He flew to Heron's house."Heron! Heron!" he called. "Why have you eaten all the fish?"Heron bustled to her door, angry and surprised at her friend's accusation."Me? Eat all the fish?" she squawked. "I barely caught anything this morning! My poor stomach has been growling all day."The two birds began to argue over who had eaten more fish. Finally, Hummingbird raised his wing to stop the debate."I do not think there are enough fish left in the river for both of us," he said. "Let's have a race. Whoever reaches the dead tree on the other side of the hills first owns all the fish. The loser has to find something else to eat."Heron agreed. They prepared to race. Hummingbird was certain that he would win. He watched Heron as she awkwardly stretched her wings and prepared to fly. This will be like catching fish in a barrel, he thought with a grin.Hummingbird zoomed past Heron as soon as the race began. He flew so far ahead that he lost sight of her behind him. He slowed down as he passed a patch of wildflowers. They smelled so sweet that he had to stop and look at them more closely. Hummingbird just had to try some of their nectar. He drank until his belly was heavy and his eyelids drooped. Perhaps just a short nap, he thought, as he settled himself into a nest of soft leaves.It was late in the day when Hummingbird woke up. He stretched his wings and glanced at the sky. He could just make out the shape of Heron, flying slowly but surely toward the dead tree. She was almost done with the race! Hummingbird zipped into the air and flew as fast as he could, but it was too late. Heron reached the tree first. From that day forward, Heron owned the fish, and Hummingbird lived on nectar.What is the theme of the story Hummingbird and Heron? A. A full stomach is not as important as friendship.B. Don't get distracted by fresh fish when racing.C. Sharing shows care for others. D. Slow and steady wins the race. Does melting sea ice in the Arctic increase sea level directly? Why or why not?
