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

Which of the following is an example of a
homologous trait?
A. the wings of bees and birds
B. the forearm of different animals
C. the DNA of land animals
Answer:
the wings on bees and birds
An example of a homologous trait is the wings of bees and birds. The correct option is A.
What are homologous traits?The Theory of Evolution can be used to explain the homologous features of related species. According to this hypothesis, species develop over time from a common progenitor.
In order to adapt to the new environment, species separated from one another and developed new features. The variety of species observed on Earth today is the result of a process known as speciation.
The homologous features that are shared by related species are proof of their shared ancestry. For instance, despite being different, the wings of a bat and a bird share characteristics.
Therefore, the correct option is A. the wings of bees and birds.

why is rna a polymer and a macromolecule
Answer:
RNA is a polymer because it is made up of many monomers called nucleotides. Moreover, RNAs can form macromolecules because many RNAs are large molecules (i.e., polynucleotide chains).
Explanation:
Ribonucleic acid (RNA) can be defined as a single-stranded nucleic acid polymer of the four nucleotides. In RNA, each nucleotide is composed of a 1-ribose sugar, a 2-phosphate group and 3-one of four types of nitrogenous bases: Adenine (A), Cytosine (C), Guanine (G), and Uracil (U), which are covalently bonded to form polynucleotide chains. There are different types of RNAs such as mRNA, tRNA, rRNA, miRNA, circ-RNAs, lncRNAs, etc. Many of these RNAs form large single-stranded (ss) molecules, i.e., polynucleotide chains. For example, an mRNA sequence may have a length of 5,000 nucleotides (5 kb) or even more, and there are RNA viruses that have more than 20000 nucleotides (20 kb) in length.
The diagram below shows a light ray striking Medium A and Medium B at the same angle. (4 points)
A rectangle labeled Medium A is drawn on the left. A ray of light travels through air and strikes the surface of medium A making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium A and makes an angle of about 15 degrees with the vertical. A rectangle labeled Medium B is drawn on the right. A ray of light travels through air and strikes the surface of medium B making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium B and makes an angle of about 25 degrees with the vertical.
Which statement is correct?
The speed of the light ray is the same in air and Medium A.
The speed of the light ray is the same in air and Medium B.
Medium A and Medium B have different densities because light refracts at different angles.
Medium A and Medium B have the same density because the light ray strikes both at the same angle.
Answer:
A the speed of the light ray is the same in air and medium

Answer:
A
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
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% glucoseWe 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 concentratedThe beaker aqueous solution is hypotonic to the tube solution → Less concentrated---------------------------------------------
