The Astronomical Unit, AU, is a measurement unit for length in general astronomy and represents the mean or the average distance of the sun from the earth.
Mathematically, in astronomy,
1 astronomical unit = 150,000,000 km
But then, 1 km = 0.621371 mile
Hence,
150,000,000 km = 150,000,000 x 0.621371 miles
≈93,000,000 miles
Therefore, 1 astronomical unit can also said to be approximately equal to 93,000,000 miles.
The correct option is B

Explanation:
a.
desalination
The process of desalination involves the removal of dissolved minerals from water so it can be used for drinking.
What is the desalination process?Desalination is the process by which mineral salts dissolved in water are removed. Currently, this process, applied to seawater, is one of the most used to obtain fresh water for human or agricultural consumption.
With this information, we can conclude that The process of desalination involves the removal of dissolved minerals from water so it can be used for drinking.

Answer:
According to the image that represents a cell in the human body, the true statement is that structure 4 is the cell membrane that provides exchange of O₂ & CO₂.
Explanation:
In cells, the cell membrane acts as a semi-permeable barrier to the passage of substances, including nutrients and oxygen (O₂).
One of the functions of the cell membrane is to allow the exchange of O₂ —necessary for the cell— and carbon dioxide (CO₂), a product of cell metabolism that must be removed.
In the image, the structure identified with the number 4 corresponds to a cell membrane of human cells that provides this gas exchange.
The other options are not correct because:

Answer:
The double helix is a description of the molecular shape of a double-stranded DNA molecule. ... Each DNA strand within the double helix is a long, linear molecule made of smaller units called nucleotides that form a chain.
Answer:
Explanation:
The double helix describes the appearance of double-stranded DNA, which is composed of two linear strands that run opposite to each other, or anti-parallel, and twist together. Each DNA strand within the double helix is a long, linear molecule made of smaller units called nucleotides that form a chain.

if glucose is in higher concentration outside the cell than inside, but the plasma membrane and other surface layers of the cell do not allow glucose to pass through, which is the most likely type of transport for glucose? and Why?
a simple diffusion
b Osmosis
c Facilitated diffusion via a gated channel
d Facilitated diffusion via an aquaporin
e Facilitated diffusion via an ion channel
Answer:
a
Explanation:
ok ok as you were saying you said it is hard for the glucose concentration in the body this also had to go out so but the plasma membranes and other surfaces layers cell layers of the layer of the soil do not allow to close glucose to pass through which is most likely type of transport type of transport for kids and you still said why it is because it gives energy to the body

A yeast cell that forms a bud is called the "mother cell." Why is there no mother cell after a paramecium divides?
There is no mother cell after a paramecium divides because it is divided by binary fission and the paramecium is divided into two identical cells, called daughter cells, there is no mother cell left.
What is paramecium?Paramecium is a protist. It is oval-shaped with cilia all over the body, and it is minute and can be seen only under a microscope. It engulfs its food through the body cavity, which is its mouth.
Binary fission means when the cell is divided into two daughter cells. The division is asexual reproduction. The cell divided DNA into two copies and then each cell gets the DNA.
Thus, there is no mother cell after a paramecium divides since binary fission is used and the paramecium is split into two identical cells, known as daughter cells.

Which statement is true about mutations?
W
A. Mutations are always beneficial.
В.
Mutations are always harmful in plants.
C.
Mutations only affect humans.
D.
Mutations can be caused by high-energy radiation.
Answer:D.
Mutations can be caused by high-energy radiation.
Explanation:
"Mutations can be caused by high-energy radiation". This statement is true. Therefore option D is correct.
Mutations are changes in the DNA sequence of an organism's genome. They can occur naturally as a result of errors during DNA replication or recombination, or they can be induced by various factors including radiation, chemicals, or environmental factors.
High-energy radiation, such as X-rays or ultraviolet (UV) radiation, has the potential to cause mutations in the DNA. This radiation carries sufficient energy to disrupt the normal structure and functioning of DNA molecules, leading to changes in the genetic code.
Exposure to high-energy radiation can result in different types of mutations, including point mutations (changes in a single nucleotide base), deletions, insertions, or rearrangements of DNA segments.
It is important to note that not all mutations are harmful or beneficial. Some mutations may have no significant effect, while others can be detrimental or even provide advantages in certain circumstances, such as adaptations to new environments or resistance to specific diseases.

The following is the results of a genotype being "foiled" for a dihybrid cross: BS | Bs | bS | bs
Determine the parents genotype
A) BBSS
B) BBss
C) BbSs
D) BbSS
Answer:
C. BbSs
Explanation:
The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.
This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.
So, the genotype must be C, BbSs
The foiled results of the genotype for the offsprings include BS | Bs | bS | bs.
The parent's genotype will then be BbSs.
The genotype of both parents have to be heterozygous as a result of the
presence of its forms in the B and S traits. There is the presence of the
dominant (B,S) and recessive traits (bs).
The genotypes of the parent will however have both traits in them which
translates to the option C) BbSs being the most appropriate.
