Answer 1

helium is an element..............

Answer 2

Answer:

A. Element

Explanation:

He is a symbol of an element called helium. Helium is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas (gas whose atoms are not bound to each other). It's the first in the noble gas group in the periodic table. As we can see in the attached image, its atomic number is 2.

Helium is known for causing people to have a high-pitched voice after being inhaled. Because it is lighter than air, when you inhale it and try to talk, the sound waves travel faster through the lower-density gas, resulting in a high-pitched voice.

The order of nucleotides in a gene affects the proper protein functioning in cells.

True or False

Answers

Answer:

True

Explanation:

The given statement is true.

• Changing the nucleotides sequence in the molecule of a DNA can change the amino acids in the final protein, resulting in protein malfunction.

• The genetic information of an organism is contained within the molecules of DNA.

• The information is stored in the proper order of sequence of bases and is organized into genes, each of the gene constitute the information required for producing a functional product.

• For example, the insulin gene comprises instructions for arranging the protein insulin from individual amino acid, when the sequence of nucleotides gets changed, the amino acids in the final protein also changes.

• This results in the improper functioning of insulin, and it fails to combine with the insulin receptor.

• This change in the sequence of nucleotides would lead to a disease state known as diabetes.

Thus, the given statement is true.

Which timeline shows the correct order of contributions made to the discovery of DNA?
(Options are in screenshots below!)

Answers

Answer:

The correct answer is B.

Explanation:

DNA was discovered in 1800, and then scientists studied DNA with X-Rays. After a while, scientists published a 3D model of DNA, and shortly after, scientists decoded DNA genes. So the answer is Option B.

Hopefully, this helps! :D

Ask your question below!

In the 1800s first the discovery of DNA was done, than the X-ray study of the DNA was done, after that the 3-D model of the DNA was developed, and finally human genetic code was decoded in the 1960s.  

• The DNA was initially identified in the late 1860s by Friedrich Meischer, a Swiss chemist.  

• After that Rosalind Franklin and Wilkins studied DNA with the help of X-ray diffraction tool.  

• In the 1953s, the 3D model of the DNA molecule was discovered by Watson and Crick.  

• Finally in the 1960s, Nirenberg and his colleagues at the National Institutes of Health deciphered the human genetic code.  

Thus, the second timeline shows the correct order of contributions made to the discovery of DNA.

repaired before cells enter mitosis?
F So that another round of DNA synthesis does not have to take place
G So that the chromosomes can align at the metaphase plate during mitosis
H So that the cytoplasm can be divided equally between the two daughter cells
J
So that healthy daughter cells are produced, allowing the organism to continue growing

Answers

Answer:

So that healthy daughter cells are produced, allowing the organism to continue growing

Explanation:

Damaged DNA is very bad for the cell. It can cause cell death or cancer, which the cell wants to avoid.

Therefore, before dividing and passing the DNA on to daughter cells, there are checkpoints to ensure that DNA replication takes place properly and that there is no damage to the DNA such as mutations or chromosome breaks.

This ensures the genetic material is intact and the cells can function normally, allowing the organism to grow.

which of the following happens to a cell in hypotonic solution
A- The cell gains water and expands
B- The cell stays the same
C- The cell loses water and shrivels
D- Water moves out of the cell

Answers

Answer:

In a hypotonic solution, the solute concentration is lower than inside the cell. If the water continues to move into the cell, it can stretch the cell membrane to the point the cell bursts (lyses) and dies

Hypotonic solutions have lower solute concentrations than cells. If water keeps entering the cell, it can strain the membrane until the cell bursts and dies. Therefore, option (A) is correct.

What is hypotonic solution?

In comparison to another solution, a hypotonic solution will have a lower solute concentration because of its composition. Without another solution to compare it to, it is impossible to determine whether a solution is hypotonic, isotonic, or hypertonic. A solution is said to be hypotonic when it has a relatively low concentration of solutes in comparison to another solution.

As a consequence of this, the solute concentration is lower in a hypotonic solution than it is inside of the cell. If the water continues to enter the cell, it has the potential to stretch the cell membrane to the point where the cell lyses and dies as a result of the rupture.

What is the function of different cell organelle in cell?

Much like an organ does in the body, an organelle is a subcellular structure that serves one or more distinct functions within the cell.

The nuclei, which contain genetic material, the mitochondria, which generate chemical energy, and the ribosomes, which put together proteins, are a few of the more significant cell organelles.

The formation of the mitotic spindle, which is essential for cytokinesis, depends on the centrioles.

Digestion is carried out by the lysosome. They aid in the removal of outdated and worm-out cells as well as foreign bodies. Cell division is aided by the centrosome.

Therefore, Label A: Nucleus label B : Lysosome Label C: Ribosomes Label D: Centriole.

What is a vascular plant

Answers

Answer: A vascular plant is any one of a number of plants with specialized vascular tissue. The two types of vascular tissue, xylem and phloem, are responsible for moving water, minerals, and the products of photosynthesis throughout the plant. As opposed to a non-vascular plant, a vascular plant can grow much larger.

Explanation: The ferns, gymnosperms, and flowering plants are all vascular plants. Because they possess vascular tissues, these plants have true stems, leaves, and roots. Vascular tissue forms a central column, also called stele, through the plant axis for the transport of different substances. Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues.
