Answers

Answer 1

Answer:

number 1 salt and peppers

number 2 false

number 3 sunlight

number 5  deep in the oceans

number 6 true

Explanation:

number 1 you can buy silver or gold you can't pick up salt a gravel and krill and plankton are not good for people

number 2  water can get heavy the more you go down there for your lung will get crushed this same effect can happen to fish

number 3 sunlight  and saltine aka(what in salt water) will change the hint is the word temperature

number 4 The basic thermohaline circulation is one of sinking of cold water in the polar regions, chiefly in the northern North Atlantic and near Antarctica. These dense water masses spread into the full extent of the ocean and gradually upwell to feed a slow return flow to the sinking regions.

number 4 I don't have a explanation for this

Answers

Number 1 is C
And im not sure about the rest :(

Storing hormones, smooth and cardiac muscles are the correct answers.

Storing hormones is not function of skeleton system. Skeleton system protects internal organs such as heart, kidney and lungs etc. It is also responsible for the movement of the muscles as well as produces blood cells because of the presence of bone marrow.

Smooth and cardiac muscles can contract without nervous system stimulation because they are involuntary Muscle which is beyond the control of the nervous system so we can conclude that storing hormones, smooth and cardiac muscles are the correct answers.

Eric has made a terrarium, a closed container with plants in it, and he has put


enough water into it to satisfy the needs of the plants. Does Eric need to add


water to his terrarium again? Why or why not?

Answers

Answer:

Yes

Explanation:

The water will be used by the plants sooner or later so their basic metabolic needs can be achieved. Also, the plants will loose their water by transpiration, in order to produce their carbohydrates. Therefore the amount of water will not be enough and has to be replenished.

Examine the picture of an onion root tip with cells in various stages of the cell cycle. A student claims that interphase is the longest stage of the cell cycle. Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why. A) Mitosis is the longest stage because anaphase requires more time to separate chromatids. B) Interphase is the longest stage because chromosomes are visible in the majority of the cells. C) Mitosis is the longest stage because the majority of the cells in the photo are replicating their DNA. D) Interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing.

Answers

Answer:

B

Explanation:

the longest phase in the cell division is interphase because the DNA replication occurs in this phase

As per the image interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing. The correct option is D.

What is cell cycle?

The cell cycle, also known as the cell-division cycle, is the sequence of events that occurs in a cell that causes it to divide into two daughter cells.

A cell cycle is the series of events that takes place in a cell as it grows as well as divides.

A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.

Interphase is the longest stage, according to the image, since the maximum of the cells in the photo have uncondensed chromatin as well as are not dividing.

Thus, the correct option is D.

of organisms in the Everglades?

Answers

Answer:

If the Burmese Python surpasses its carrying capacity, the other organisms might not have enough food, or there is barely a chance of survival for the pythons' prey. The population sizes of other organisms might go down, and go to..extinction :/.

Explanation:

If the Burmese Python exceeds its carrying capacity, other creatures may starve or the pythons' prey may not survive. Other creatures' populations may go extinct.

What is carrying capacity?

The typical number of individuals belonging to a species that are found in a given ecosystem is one definition of carrying capacity. The population size of the species is restricted by environmental conditions such as the availability of sufficient food, shelter, water, and mates. In the event that these requirements are not fulfilled, the population will continue to decline until the resource levels recover.

Therefore, if the Burmese Python population grows above its carrying capacity, the other creatures in the area may not have access to enough food, and the prey of the pythons will have an extremely low chance of surviving. It is possible that the population sizes of other organisms will decrease, leading to their eventual extinction.

Explanation:

Before mitosis begins, which happens before the nucleus starts dividing?
The DNA replicates.
The cytoplasm separates.
The sister chromatids separate.
The homologous chromosomes cross over.

Answers

Answer:

The DNA replicates.

Before mitosis begins, the DNA replicates. During the S phase of interphase, which precedes mitosis, the DNA in the nucleus undergoes replication, resulting in the formation of identical sister chromatids.

This ensures that each daughter cell produced during mitosis receives a complete set of genetic information.

After DNA replication, the cell enters the mitotic phase, during which the nucleus divides and the replicated DNA is distributed to the daughter cells.

The cytoplasm separates during cytokinesis, which occurs after mitosis and is not directly related to events before nucleus division. The separation of sister chromatids occurs during anaphase of mitosis, not before the nucleus starts dividing.

Thus, the process of homologous chromosomes crossing over occurs during meiosis, not mitosis.

In fruit flies, the gene for eye color is located on the X chromosome, and the red eye allele (R) is dominant
to the white eye allele (r). A carrier female is mated with a male fly with genotype X
rY. Which of the
following statements best describes the expected outcome of the cross?
a. The chance of an offspring having red eyes is 75%
b. The chance of an offspring having white eyes is 50%
c. The chance that a male offspring will have white eyes is 0%
d. The chance that a female offspring will have red eyes is 100%

Answers

Answer:

b. The chance of an offspring having white eyes is 50%

Explanation:

So the genotype of the male fly is X^r Y. This means the male has white eyes because he only has one X chromosome, so he will express whatever allele is on that chromosome.

The genotype of the female fly, though, is X^R X^r. This is because carriers are heterozygous for traits, and the sex chromosomes of most females is XX (with some exceptions, like XXX, or X (Turner syndrome)).

If we cross this, what are the outcomes? Do a Punnett square. You get the genotypes of X^r X^R, X^r X^r, X^R Y, and X^r Y. The expected phenotypes are a red eye female, white eye female, red eye male, and white eye male.

Now, let's look at the choices:

A.: The chance of an offspring having red eyes is not 75%; it is 50%.

B.: The chance of an offspring having white eyes is 50%!!!

C.: The chance that a male offspring will have white eyes is 50%, not 0%.

D.: The chance that a male offspring will have white eyes is 50%, not 100%.
