Write down the functions of
1.microtubules
2.tripletsof microtubules

Answers

Answer:

Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility

Centrioles are cylindrical structures that are made up of protein tubes called microtubules. Specifically, nine groups of three microtubules, known as triplet microtubules, are linked together to make the walls of the cylinder.

Hope it helps :)

Answer:

Microtubules have several functions. For example, they provide the rigid, organized components of the cytoskeleton that give shape to many cells, and they are major components of cilia and flagella (cellular locomotory projections). They participate in the formation of the spindle during cell division (mitosis).

triplet microtubules are linked together to make the walls of the cylinder.

Explanation:

A tube with a membrane covering the bottom is placed in a beaker. The membrane allows water to flow through but not salt or glucose. The tube contains an aqueous solution with 4% salt and 20% glucose and the beaker contains an aqueous solution with 12% salt and 6% glucose. How could you describe the solution in the beaker compared to the solution in the tube

Answers

Answer:

The solution in the tube is hypertonic to the solution in the beaker.

Explanation:

To compare the solutions, find the total amount of solutes in both the tube and beaker.

The tube has 4% salt and 20% glucose, so it has 24% solute.

The beaker has 12% salt and 6% glucose, so it has 18% solute.

Since 24 is larger than 18, this means the tube has more solute.

Since the tube has more solute and less water compared to the beaker, it is hypertonic to the beaker.

So, the answer is that the solution in the tube is hypertonic to the solution in the beaker.

Solutions are hypertonic or hypotonic to other solutions according to their solute concentration grade. In the exposed example, the beaker aqueous solution is hypotonic to the tube solution, meaning it is less concentrated.

--------------------

Available data:

The membrane allows water to flow through but not salt or glucoseThe tube contains an aqueous solution with 4% salt and 20% glucoseThe beaker contains an aqueous solution with 12% salt and 6% glucose

We need to describe and compare solutions.

To do it, first, we will review some theoretical framework.

When talking about solutions in compartison with the cell content, we can classify them as follows,

HYPERTONIC ⇒ A hypertonic solution has a higher concentration of solute than the cell. This means that in the cell interior, the solute concentration is lower than in the solution itself.

ISOTONIC ⇒ The solute concentration is the same inside the cell and outside.

HYPOTONIC ⇒ A hypotonic solution has a lower concentration of solute than the cell. This means that in the cell interior, the solute concentration is higher than in the solution itself.  

When a cell is in a hypotonic solution, through osmosis, water moves toward the cell.  

Osmosis is the phenomenon that occurs when two dilutions of different concentrations -in this example, the interior of the tube and the beaker- are separated by a semipermeable membrane.

The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.  

What we need to consider is

• When a cell with semipermeable membrane is placed in a hypotonic solution, water enters the cell.

• When a cell with semipermeable membrane is placed in an isotonic solution, there is no water movement.

• When a cell with semipermeable membrane is placed in a hypertonic solution, water gets out of the cell.

In simple words, in the proposed experiment, glucose and salt -solutes- can not cross the membrane, but water can. The tube represents a cell. So,

The tube has 4% salt and the beaker 12 % saltThe tube has 20% glucose and the beaker 6% glucose.

To make the analysis easier, we can add the concentration percentages of glucose and salt at each side of the membrane, and then compare them.

The tube contains an aqueous solution with 24% solute (4% salt + 20% glucose)The beacker contains an aqueous solution with 18% solute (12% salt + 6% glucose)

We can see that the concentration of solute is higher in the interior of the tube than in the beaker. This difference suggests that water will move forward to the tube interior.

According to this analysis, we can say that

The tube aqueous solution is hypertonic to the beaker solution → More concentrated

The beaker aqueous solution is hypotonic to the tube solution → Less concentrated

Which of the following can be inferred from the genetic code?

A.All organisms have a common biochemical evolutionary origin.

B.Organisms can live without genetic code.

C.Four nucleotides.

D.Four nucleosides.

Answers

Answer:

A. All organisms have a common biochemical evolutionary origin.

Explanation:

Genetic code is the biological mechanism by which the DNA in our body is used to synthesize protein needed for growth and development. The genetic code comprises of all the possible 64 codons i.e. a group of three nucleotides that encode an amino acid.

One of the characteristics of the genetic code is that it is UNIVERSAL. This means that all known living organisms make use of the same genetic code and hence, this portrays that all living organisms share a common biochemical evolutionary origin.

C. Mammal cells have more precise restriction enzymes.
D. Bacteria make proteins differently than mammals, and cannot make certain human proteins.

Answers

Answer:

C

Explanation:

As mammal cells have more precise restriction enzymes, it sometimes needed instead of bacteria. The correct option is C.

What is genetic engineering?

Genetic engineering also referred to as genetic modification is a process that uses laboratory-based technologies to alter an organism's DNA makeup.

Because mammalian cells have more precise restriction enzymes, it is sometimes necessary to use them instead of bacteria.

Herbert Boyer and Stanley Cohen, biochemists, create genetic engineering in 1973 by implanting DNA from one bacteria into yet another.

There are three basic stepping stones to genetic engineering. These are:

Isolating DNA fragments from a donor organism.Inserting an isolated donor DNA fragment into a vector genome.Growing a recombinant vector in an appropriate host.

Thus, the correct option is C.

B. Gap 2
C. Development
D. Mitosis

Answers

Answer:

C. Development

Explanation:

The interphase stage consists of Gap 1 (G1) phase, Synthesis (S) phase and Gap 2 (G2) phase while the mitotic phase consists of mitosis and cytokinesis etc. Hence, according to the question, development is not a stage of the cell cycle.

The "homunculus" constructed on the basis of somatosensory representations in the human primary somatosensory cortex

Answers

Answer:

The correct answer is -

a. has a grossly enlarged face and hands compared to torso and limbs

c. is distorted because of the disproportionate representation of certain body parts relative to others in the somatosensory cortex

Explanation:

" Homunculus" is a graphical representation of a small but fully grown man which the foetus is believed to develop whereas somatosensory homunculus is a neurological representation of the brain of humans that shows the motor and sensory functions of the body.

It has a large number of sensory nerves from the hand that take a large part of the brain. The face also has many nerve endings and are represented by large areas of the homunculus. A distorted look comes from this uneven representation of different body parts in the homunculus.
