Answers

Answer:

Due to different reproduction methods.

Explanation:

Organisms from eubacteria, plantae and animal kingdom are used different reproductive strategies which leads to genetic diversity. Bacteria use asexual reproduction which produces identical offspring while on the other hand, plants and animals use sexual reproduction that produces offspring that is different from plants which leads to variation in the organism so that's why we can say that different reproductive strategies is responsible for genetic diversity.

In what ways is a eukaryotic cell similar to a city?

Answers

Answer:  In many ways, the eukaryotic cell is kind of like a city. I will tell you what each of the organelles in a cell does. Your job will be to try to match each of the cell parts to the parts of a city and explain why they are similar. a) Golgi Apparatus: packages up proteins and labels them for distribution to other parts of the cell.

Each one, like the organs inside your body, fulfills a particular function that is required for the cell to stay alive. Consider the cells to be a miniature city. Because they all do similar jobs, the organelles could represent companies, places, or parts of the city.

What is a cell?

Cells are the fundamental building blocks of all life. Gazillions of cells make up the human body.

They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.

Each one, like the organs in your body, performs a specific function that is required for the cell to survive. Think of the cells as a miniature city.

Because cell city has jobs that a plant cell does not, it represents an animal cell. In cell city, we believe that a waste disposal plant performs the same function as lysosomes, an organelle found only in animal cells.

Thus, this way, a eukaryotic cell similar to a city.

If Darwin knew of Mendel's work, how might it have influenced his theory of evolution? Do you think this would have affected how well Darwin's work was accepted?

Answers

Answer:

See explanation

Explanation:

According to Darwin, the determinant of the ability of species to thrive in their environment is their ability to develop favourable characteristics which enable them to survive in their environment. This ability to develop favourable characteristics is called natural selection.

These favourable characteristics are passed on from parents to offsprings and are responsible for the perpetuation of organisms having these favourable characteristics in comparison to other members of the same species.

In relation to Mendel's theory, these favourable characteristics could be regarded as Mendel's factors (currently identified as genes). These factors are units of inheritance passed on from parents to offsprings.

If Darwin had an idea of Mendel's work when he propounded his evolution theory, he could have modified his idea of favourable characteristics to imply genes. This would have made his idea more empirical than speculative and led to a faster world wide acceptance of his ideas.

7. You and your lab partner are doing an experiment in the physiology lab. Each of you has an isolated muscle cell and you are supposed to stimulate it with an electrode as soon as its absolute refractory period ends. Your partner has a cardiac muscle cell and you have a skeletal muscle cell. Which one of you will use your electrode more times in one minute

Answers

Answer: I will use the electrode on the skeletal muscle cell more times in a minute than my partner will.

Explanation:

Based on the information given, an electromyograph tracing can be used on order to know when to use the electrode for the scenario explained.

An electromyograph is simply a machine that is used for the detection and the recording of the electrical potential that's been generated by muscle cells when such muscle cells are activated.

Due to the fact that a skeletal muscle cell while my partner has a cardiac muscle cell, I'll have to use the electrode on the skeletal muscle cell more times in a minute than my partner will.

Jaleel and Lisa are simplifying the expression 2 (x minus 2) + 2 as shown. Jaleel's Method 2 (x minus 2) + 2 = 2 x minus 4 + 2 = 2 x minus 2 Lisa's Method 2 (x minus 2) + 2 = 2 x minus 2 + 2 = 2 x

Answers

Answer:

Jaleel is correct

Explanation:

Given

[tex]2(x - 2) + 2[/tex]

Jaleel

[tex]2(x - 2) + 2 = 2x - 4 + 2 = 2x - 2[/tex]

Lisa

[tex]2(x - 2) + 2 = 2x - 2 + 2 = 2x[/tex]

Who is correct

Analyzing the solutions

For, Jaleel; we have:

[tex]2(x - 2) + 2 = 2x - 4 +2[/tex] --- this is correct

[tex]2(x - 2) + 2 = 2x - 2[/tex] --- this is correct

For Lisa, we have:

[tex]2(x - 2) + 2 = 2x - 2+2[/tex] --- this is incorrect because:

[tex]2(x - 2) + 2 \ne 2x - 2+2[/tex]

In a well-fed human eating a Western diet, the richest source of stored chemical energy in the body is ________. glucose in the blood fat in tissue calcium phosphate in bone glycogen in muscle cells protein in muscle cells

Answers

Answer:

fat in tissue

Explanation:

Biomolecules like carbohydrates, fats etc. are well known for their energy storing abilities. Glucose, as a carbohydrate, is the most used source of energy but is stored in excess as glycogen in the muscle and liver cells.

However, fats are far more efficient in storing energy than carbohydrates or proteins because they give more ATP per molecule. Fats are stored in tissues of the body called ADIPOSE tissues. Hence, the richest source of stored chemical energy in the body is FATS IN TISSUES.

A)Exons 2 and 3 must have the same number of nucleotides. B)Exons 2 and 3 must contain an integral number of codons (that is, the number of nucleotides divided by 3 must be an integer). C)Exons 2 and 3 must contain a number of nucleotides that when divided by 3, leaves the same remainder (that is, 0, 1, or 2). D)Exons 2 and 3 must have different numbers of nucleotides. Multiple Choice

Answers

Answer:

Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.

Suppose D were dominant and d were recessive, and you could label the D allele in the P generation with a radioactive substance that could be inherited over several generations. You create hybrids by mating your radioactive DD individuals to dd individuals. Finally, you cross two F1 individuals (with the Dd genotype). In 1,000 offspring, how many would you predict would be radioactive?

Answers

Answer:

750 offspring

Explanation:

The correct answer would be 750 offspring.

The D allele has been labeled with radioactive substance.

If you cross Dd and Dd:

         Dd    x    Dd

     DD   Dd   Dd   dd

3/4 of the resulting offspring would have, at least, the D allele.

Hence, out of 1000 offspring,

     3/4 x 1000 = 750

750 would possess the radioactive label.

Synthesis of proteins that are coded for by mRNA
Copying of DNA to form an mRNA strand
Replication of DNA to produce a complementary DNA strand
mRNA folding up by forming complementary bonds with itself

Answers

Answer:

Copying of DNA to form an mRNA strand

Explanation:

In transcription, DNA is copied to form an mRNA strand with complementary bases.

The DNA strand being copied during the process is called the template strand, and the mRNA that is made will be created from that strand.

This is the first step of protein synthesis.

This strand of mRNA is further used during translation, where it is used to code for amino acids to make proteins.

So, the correct answer is Copying of DNA to form an mRNA strand

Answer:

B

Explanation:

Transfer RNA (tRNA) is an RNA molecule involved in the process of translation by which cells synthesize proteins. These molecules (tRNAs) have 76-90 nucleotides in length which form characteristic stem-loop structures, and they are considered adaptor molecules because tRNAs serve as the physical link between the messenger RNA (mRNA) and specific amino acid residues of the growing polypeptide chain. A tRNA is composed of a trinucleotide region (i.e., the anticodon region) that binds to the codon in the mRNA, and a region that attaches to a specific amino acid in order to transfer it to the ribosome, where protein synthesis takes place.
