An expiriment was done to determine if the rate at wich a patato cooked depended on the temperature of water in which it was boild. What are the independent and dependent variable??​

Answers

Answer:

The independent variable  is  the  potato   and dependent variable  will  be  the  temperature

Explanation:

When  this  experiment  is  done  it  consider  about  the  boiling  rate  of  the  temperature  which  it  helps  to  cook  the  potato.  in  other  words  when  you  do  this  experiment  you  will  try  different  temperature  levels  on  the  same  type  of  vegetable  which  is  a  potato.  so  the  variable  called  temperature  will  be  dependent  because  its  the  variable  that  we  change.  and  the  variable  called  potato  will  be  the  independent.

Which of the following areas is located in the frontal lobe of the brain?
Broca's area
O hippocampus
thalamus
Wernicke's area

Answers

Answer:

Brocas area

Explanation:

Broca's area is located in the frontal lobe of the brain.

The brain region known as Broca's area is located in the left frontal lobe and is considered the nucleus that controls expressive language.

Thus, in both writing and speech, this portion of the central nervous system specializes in the production of a message with internal coherence and articulated through the language fractions.

In this area, specifically, there are capacities such as:

• Order the phonemes when making a word.

• The organization of words within a sentence.

• The semantic integration of the content to be expressed.

• Motor planning necessary for the expression of language.

Therefore, we can conclude that Broca's area located in the third gyrus in the frontal lobe is responsible for the articulation of language in any of its forms.

4. If you are male, which member of your family should you look at to tell whether you are going to
go bald? Why? Use a punnett square to prove your answer.

Answers

Answer:

Your mother

Explanation:

If you are a male, the member of the family you should look at to tell whether you are going to go bald is your mother.

Baldness is a sex-linked recessive trait and as such, the two X chromosomes in females need to carry the allele in order for females to be phenotypically affected for the disorder. The males having only one X chromosomes however, means that they only need that single X chromosome to carry the baldness allele in order for them to be affected for baldness.

Assuming the allele for baldness in represented by b. Your mother is affected for baldness while your father is free from the disorder. This means that the genotype of your mum would be [tex]X^bX^b[/tex] while that of your dad would be [tex]X^BY[/tex]. According to law of inheritance, males usually inherit their X chromosomes from their mother. This means that any male your mother gives birth to would have the genotype [tex]X^bY[/tex] which phenotypically means that they will be affected for baldness.

The attached image shows the Punnet's square analysis of what will happen during inheritance.

Which problem would quickly occur in a plant when the xylem is not functioning properly?
A. The plant would wilt.
B. The plant would turn yellow.
C. The plant would stay very small.
D. The plant would not produce seeds.

Answers

Answer:

A. The plant would wilt.

Explanation:

In order to stay healthy and fresh, plants like every other living organism require certain substances. One of those substances is WATER, which the plant gets by absorption via the root hairs. The water circulates throughout the plant with the aid of a water-conducting vascular tissue called XYLEM. Without the xylem, water will not be transported throughout the plant.

The xylem tissue helps provide structural support to the plant as it helps the plant cell to be turgid. A non-functional xylem means the conduction of water is impossible, hence causing the plant cells to become flaccid and lose strength; a process called wiltering.

A scientist has sequenced a gene from a multicellular eukaryotic organism. Brendan claims that by analyzing the gene sequence and applying

Which statement provides the strongest evidence against the validity of Brendan's claim?


A. Regulatory proteins may activate or deactivate a gene, often by very complex mechanisms.




B. During transcription, a strand of mRNA is synthesized from complementary base pairs, with the substitution of uracil (U) for thymine

(T)




C. During translation, anticodons on tRNA bind to codons on mRNA as part of the process that forms the polypeptide.




D. After a gene is transcribed, introns are removed from the pre-mRNA to form the mRNA that is translated.

Answers

Answer:

D. After a gene is transcribed, introns are removed from the pre-mRNA to form the mRNA that is translated.

Explanation:

According to this question, a gene was sequenced by scientists from an eukaryotic organism. Brendan claims he can conclude the resulting protein after the transcription and trans of the gene.

It is true that transcription and translation are the processes that a gene undergo in order to be expressed i.e. produce protein. However, a gene sequence contains both the coding and non-coding regions in it. The coding regions code for a protein and are called EXONS in the mRNA while the non-coding regions do not encode proteins and are called INTRONS in the mRNA.

These introns are removed from the mRNA molecule that results from the transcription of a gene. The mRNA undergoes a process called SPLICING, which removes the non-coding part of the mRNA (introns) and joins the coding parts (exons).

Hence, if this occurs, Brendan will not be able to accurately conclude the resulting protein from that gene sequence because a portion of that gene will still be removed during SPLICING of post-transcriptional processing.

Answers

Answer:

D. Aphanite

Explanation:

A.P.E.X

An invasive igneous body is aphanite. Thus, the correct option is D.

What are Aphanite rocks?

Aphanite's are igneous rocks that were formed by rapid cooling in a volcanic or hypabyssal setting and are so finely grained that their individual mineral crystals cannot be seen with the unaided eye.

Very fine-grained, crystalline fabrics called aphanitic minerals are created when a magma solidifies in reaction to an exceptionally rapid loss of heat and dissolved gases. They are characterized by grains that are too small to be recognized without a petrological microscope.

Large crystals are known to be present in certain specific igneous rocks. The crystals in this type of rock are approximately the same size. Compared to aphanitic rock, which is known to have rocks with finer grain sizes.

So, the correct option is D.

5. If there is a large number of prey rodents, the number of owls will increase due to a healthy
food source. More owls feeding on the rodents will cause their population to decrease, which in
turn will eventually cause the owls number to decrease. Would you expect to find this pattern in other ecosystems between predators and prey? Explain.

Answers

Answer:

Yes

Explanation:

One would expect to find the same pattern in any other ecosystems between predator and prey unless there is a way the prey's population is being replenished.

When predators start hunting down preys, the population of preys start decreasing and this will in turn means less food for the predators. If the trend continues, competition for food become fierce among the predators and this will make their population to start decreasing as the competitively strong ones take over the little food that remains and the competitively  weak ones are gradually left to starve to death.

Organisms may contain up to five levels of organization within their bodies. Which level of organization is best represented by
the liver?

Answers

Answer:

ORGAN

Explanation:

The liver is a very important organ in the system of multicellular organisms e.g humans. It performs various functions in the body e.g. detoxification, metabolism etc. As rightly said in this question, multicellular organisms are made up of five levels of organization.

Firstly, all living organisms are made up of CELLS, which are the basic unit of life. Cells come together to form the TISSUE. Tissues that perform similar functions come together to form the ORGAN, the organ that specifically play a similar role in the body are collectively called ORGAN SYSTEM. The various organ systems make up the whole ORGANISM.

In this five level of organization, the liver falls under the ORGAN category because it is made up of cells called Hepatocytes, which come together to form tissues. The tissues collectively make up the LIVER.
