In Percy jackosn

Answers

Answer:

If it is the scene that I think you're referring to, they were sitting in a group on rocking chairs, cutting yarn.

Explanation:

in Greek mythology, these women are the three Fates, named Clotho, Lachesis, and Atropos. In mythology, a thread represented someone's lifeline, and when the Fates cut your thread, it meant your life was over and you died.

In this specific scene, from The Lightning Thief, the Fates are seen cutting a blue piece of yarn, which makes Percy's friend Grover nervous because he believes they've just cut Percy's lifeline.

In flies, red eye color (Xa) is a sex-linked recessive trait. Black eyes (XA) are the normal colored eyes for flies. What are the chances
that a carrier mom and a black-eyed dad will have (hint: you must use X's and Y's):
a. a red eye male as their next offspring?
b. a black eye female as their next offspring?
2.
3
4.
5 6 7 8 9 10

Answers

Answer:

The correct answer is -

a. a red-eye male as their next offspring? = 25%

b. a black eye female as their next offspring? = 25%

Explanation:

The given question says that in flies the red eye color is a sex-linked recessive trait which means it will only appear in the presence of two copies of the recessive allele in females and one copy of recessive allele in male as there is only one copy of X chromosome is present in males the other chromosome is Y.

So, the genotype of carrier mom would be XaXA and normal black eye male would be XAY, then cross between these flies:

        XA          Y

Xa     XaXA    XaY

XA   XAXA     XAY

On the basis of red eye male would be XaY = 1/4 = 25%

and the black eye female would be XAXA  = 1/4 = 25%

Analyze the effects of DNA mutations
on the
of an organism.

Answers

Answer:

DNA mutations or Chromosomal mutations are also called chromosomal aberrations, chromosomal abnormality, or chromosomal disorders, all indicating a possible alteration in the morphology and structure of the chromosome.

DNA mutations lead to abnormalities in the function of the cell and organism, as chromosomal or DNA mutations can result in abnormal gene numbers or positions.

These are known to cause different genetic diseases that can be hereditary and are transferred from one generation to another.

These mutations, however, do not always affect the functioning of the cell as some mutations might affect regions of chromosomes that do not make up the genetic makeup of the organism.

Even though gene mutations are usually more severe than chromosomal mutations, some chromosomal mutations might result in gene mutations.

6. Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide. The enzyme increases the rate of reaction, so it is 700 times faster. If the enzyme reaction took 1.9s how long would the reaction take if there was no enzyme? Convert the answer to minutes. Give your answer to 4sf.

Answers

Answer:

0.00004524 minute

Explanation:

The enzyme is Catalase, and it speeds up the rate of reaction by 700 times than what it was supposed to be.

If the already sped up rate of reaction is 1.9 seconds, then the initial reaction ought to have taken

1.9/700 seconds and that is 0.0027143 second.

We're asked to convert to minute, we then have

0.0027143/60 which is equal to 0.0000452381 minute.

Since we're asked to round off to 4 significant figure, we have 0.00004524 minute.

Part A: Design a food chain with four trophic levels, and identify the organism in each level. What happens to energy as it travels from the bottom up? (3 points)
Part B: Can humans ever occupy the lowest, or first, trophic level? Why or why not? (1 point)

Answers

Answer:

Part A: Primary producer - plants (ex: sunflowers), Primary consumers- herbivores(ex: rabbits), Secondary consumers - omnivores and carnivores (ex: snake), tertiary consumers - omnivores and carnivores (ex: foxes), A-p-e-x predators - can be omnivores or carnivores (ex: coyote)

Energy decreases as it travels from the bottom of an energy pyramid, every time energy passes from one tropic to another, the predator only gets 10% of the total energy, or the stored energy, the rest of the energy has already been used up.

Part B: Humans cannot ever occupy the lowest or first tropic level, because the first tropic level is for producers like plants, humans are not producers and therefore cannot be at the first tropic level.

How do shale oil and tar sands compare to conventional
(regular) oil deposits?

Answers

Answer:

Oil shale is a form of sedimentary rock that contains kerogen, which is released as a petroleum-like liquid when the rock is heated. Tar sands are a combination of clay, sand, water and bitumen, which is a heavy hydrocarbon.

Additional info:

The term oil sands refers to a particular type of nonconventional oil deposit that is found throughout the world. Oil sands, sometimes referred to as tar sands, is a mixture of sand, clay, other minerals, water, and bitumen. The bitumen is a form of crude oil that can be separated out from the mixture.

The primary distinction between crude or conventional oil and shale oil is the way it collects. The oil in shale is typically found in smaller batches. As a result, shale oil often needs to be fractured so that the oil trapped within the shale can be recovered.

Answer:

please give me brainlist and follow

Explanation:

Oil shale is a form of sedimentary rock that contains kerogen, which is released as a petroleum-like liquid when the rock is heated. Tar sands are a combination of clay, sand, water and bitumen, which is a heavy hydrocarbon. Like the kerogen in oil shale, tar sands' bitumen can be upgraded to synthetic crude oil.

and function of organisms.
Chromosome

Answers

Answer:

- DNA is wrapped around nucleosomes and condensed into chromosomes.

- Proteins affect the traits and function of organisms.

Explanation:

Nucleosomes are the basic unit of compaction of DNA. Each nucleosome is composed of ~148 bp double-stranded DNA and an octamer of histone proteins, which include two molecules of each core histone: H2A, H2B, H3 and H4. Subsequently, nucleosomes are packaged into chromatin fibers so they can be densely compacted into chromosomes. On the other hand, proteins are molecules that play important (structural and enzymatic) functions in a cell. These proteins may affect the structure/function of a cell, thereby affecting a certain characteristic/trait to develop.
