A. Earth's atmosphere is deep enough to allow water to cycle through
its solid, gas, and liquid states.
OB. Earth's surface is continually bombarded by comets, which add
liquid water.
OC. Earth's distance from the sun keeps the temperature just right for

Answer:

Explanation:

water boils at 100 degrees Celcius and freezes at zero degrees Celcius. if you want to keep water in a liquid phase, the temperature has to be between 0 and 100 therefore earth is the only planet that is able to keep water in a liquid phase as it is not too hot nor too cold

A student made a model of a cell. First, she filled a clear plastic bag with gelatin.
Then, she added a rubber ball.
What are two limitations of the student's cell model?

A. The model is not as easy to see and hold as a real cell is.

B. The model does not show that cells can contain smaller structures inside
them.

C.The model does not show how a real cell gets the energy it needs to live.

D.The model is made up of materials that are different from those found in
real cells.

Answers

B) the model does not show that cells can contain smaller structures inside.

This is true because only a rubber ball was added, indicating that only a nucleus or any one organelle is present in a cell. However, the cell contains more than one organelle from the nucleus, mitochondria, Golgi apparatus, smooth and rough endoplasmic reticulum, ribosomes, and more.

Another possible answer would be D since they model does not show the process of cellular respiration where cells undergo this process to create ATP in the mitochondria.

What are Vascular tissues?

Vascular tissues in plants are specialised tissues which transport nutrients and water through the plant. They are made up of two distinct kinds of tissues: xylem and phloem.

Xylem is in charge of carrying water and minerals that are dissolved from the plant's roots to its leaves. It is made up of many cell types, such as tracheids, vessel components, and fibres. Tracheids and vessel elements are long, hollow structures that create lengthy tubes when stacked end to end.

Sugars and other organic compounds are transported from the leaves to the remainder of the plant by phloem. There are two sorts of cells in it: sieve tube elements and cell companions. Sieve tube components are long, narrow cells that run end to end.

Therefore, the vascular tissues identify as:

a. phloem

b. xylem

The cumulative work of many scientists can often be summarized as theories or laws. how is a theory different from a law

Answers

Answer:

A law is something in science that can be proved through experimenting. When the experiment is done properly, the same outcome will be achieved every time. A law does not attempt to explain why something is the way it is, it only states it.

A theory is an idea that has a large amount of scientific data backing it and is the accepted answer by most scientists, but there is no way to experiment on a scientific theory. A theory will never be able to become a law. A theory explains what it is describing.

Use the following information to calculate the correct frequencies: In a population of
Pennsylvanians, only 18% of individuals express the recessive trait of Syndactyly or webbed finger
(formulas: p+q=1 and p²+2pq+q2²=1)
a. What percentage of the population are not Webbed?

Answers

If we have the recessive genotypic frequency, we can calculate the phenotypic frequencies in a population in Hardy-Weinberg equilibrium. The percentage is 82%.

What si the Hardy-Weinberg equilibrium theory?

The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies remain the same through generations in a population that is in equilibrium.  

The allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,

Allelic frequencies

The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is q

Genotypic frequencies after one generation are

H0m0zyg0us dominant genotypic frequency,

2pqHeter0zyg0us genotypic frequency,

H0m0zyg0us recessive genotypic frequency.

The addition of the allelic frequencies equals 1

p + q = 1.

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

Available data:

18% of individuals express the recessive trait of Syndactyly

Let us say that the dominant allele is A and the recessive allele is a.

The dominant allele A codes for normal finger.The recessive allele a codes for webbed finger.

Assuming this gene expresses complete dominance,

H0m0zyg0us dominant and heter0zyg0us -AA and Aa- individuals have normal finger.

Their frequency in the population is p² + 2pq.

h0m0zyg0us recessive -aa- individuals have webbed finger.

Their frequency in the population is .

Individuals that express Syndactyly have webbed finger and their genotype is h0m0zyg0us recessive, aa. Their frequency in the population is .

q² = 18% = 0.18

We can get the frequency of individuals with normal fingers by clearing the following equation,

p² + 2pq + q² = 1

p² + 2pq + 0.18 = 1

p² + 2pq = 1 - 0.18

p² + 2pq = 0.82

The frequency of individuals with normal fingers is p² + 2pq = 0.82 = 82%.

The percentage of the population are not Webbed is 82%.

a. translation

b. protein synthesis

c. genetic sequencing

d. transcription

Answers

Translation

Translation is - The code on the m-RNA is translated into a changing of amino acids that make a specific protein. Occurs at the ribosomes

The central dogma is the process of the formation of the protein from DNA. The polypeptide chains formed from mRNA are produced through translation. Thus, option a is correct.

What is translation?

The translation is the central dogma process that translates the transcripted mRNA copy into amino acids that interlink with peptide bonds to produce polypeptide chains. Translation occurs outside the nucleus.

The duplicated DNA undergoes transcription to produce an mRNA copy that gets transported to the ribosome that translates the mRNA with the help of the tRNA and rRNA to yield chains of amino acids that produce proteins.

Therefore, the mRNA is transported to the ribosome and gets translated to proteins through the process of translation.

Make up question what does chlorine take off your make up faster than water? Should Supreme Court justices have life tenure? Recent studies have shown that since 1970, justices are serving much longer terms on the Court than ever before (more than 25 years on average), with the average interval in time between vacancies also increasing (see Steven G. Calabresi and James Lindgren [2006], "Term Limits for the Supreme Court: Life Tenure Reconsidered," Harvard Journal of Law and Public Policy, 29:769877). Gone are the days of a short-term justice like Sherman Minton. Law professor Sandy Levinson, in his book Our Undemocratic Constitution, says that it's troublesome that Supreme Court justices now stay on the Court for decades. Why might that be a problem? Consider this question from a democratic sense, particularly when one considers the fact that ideology (and not the law) often influences the most important decisions of the Court. Should justices have a time limit on how long they can serve on the Court? Nothing in the Constitution requires that there be exactly nine people on the Supreme Court.
