The example of elemental carbon is diamond and it is pure form of carbon. Thus, option A is correct.

Elemental carbon is pure form of carbon and it does not contain other elements and present in natural form. Due to this reason it is known as elemental.

In elemental form pure atoms are not attached to any other atom. Example is diamond which is allotrope of carbon in which there is only carbon atom attached to each other.

Methane and proteins are compounds consist of a combination of carbon and other elements and they are not come in category of elemental carbon.

Therefore,the example of elemental carbon is diamond and it is pure form of carbon. Thus, option A is correct.

Microscopes use lenses to magnify objects. A simple microscope uses only one lens; a magnifying glass could be called a simple microscope. The magnification of a simple microscope doesn't need any calculation because the single lens is usually labeled. A hand-lens, for example, might be labeled with 10x, meaning the lens magnifies the object to look ten times larger than the actual size.

The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).

1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).

Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).

Now we can express the ratio between 92 mL and 88.72 mL:

92 mL : 88.72 mL

Simplifying the ratio by dividing both sides by the greatest common divisor, we get:

46 : 44

So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

Explanation:

Telophase is a stage of the eukaryotic cell cycle, which is composed of interphase, mitosis, and cytokinesis.

What is a eukaryotic cell?

A eukaryotic cell is a type of cell that contains a nucleus and other organelles enclosed within a membrane. Eukaryotic cells are found in all multicellular organisms, including plants, animals, fungi, and protists. They are distinct from prokaryotic cells, which are found in single-celled organisms, such as bacteria.

Telophase is the final stage of both mitosis and meiosis, which are processes that divide the nucleus of a single cell into two daughter nuclei.

During telophase, the two daughter nuclei form and the nuclear envelope begins to reform around each daughter nucleus. The chromosomes also condense into chromatin and the spindle fibers begin to break down.

The process after telophase is called cytokinesis, which is the process in which the cytoplasm of the cell is divided up into two daughter cells.

Answer:

At what rate do the mitochondria of the cell need to convert glucose to usable

energy molecules to meet the high energy needs of the cell?

Explanation:

Organelles are organ-like structures found in cells. The are responsible for the specific actions carried out by each cell. Each organelle has its own specific role to play. However, missing or damaged organelles can have effects on the cells.

Mitochondria are organelles found in cells of all eukaryotic living organisms e.g animal, plants as they are responsible for the synthesis of energy in form of ATP. Since the cells being investigated in this question is a MUSCLE CELL, which is only found in animals, then an appropriate organelle must be investigated.

The appropriate to be asked to know if muscles cells are functioning properly is: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?.

Note that, other options are incorrect because muscle cells do not have chloroplast and cell wall, while ribosomes are not site for glucose production.

Answer:

Osteoclasts

Explanation:

The osteoclasts are enormous cells, with more than one nucleus, that originate from the bone marrow. Osteoblasts play a significant role in bone remodeling i.e. new bone growth, by helping to break down bone tissues- a process called BONE RESORPTION.

The osteoclasts perform an opposite role to that of osteoblasts (bone-forming cells). They degrade the mineral content of bone tissues and digest the remaining parts intracellularly in their vacuole. Calcium is released into the bloodstream after resorption of bones.

Therefore, according to the question, the fragments of a broken bone will be initially broken down by cells called OSTEOCLASTS before new bone tissue growth can occur.

Bone tissue destruction occurs from cells called osteoclasts. Bone building occurs from osteoblasts. Bone cells themselves are called osteocytes.

The fluid in the cochlea moves in response to vibrations from the oval window. 25,000 nerve endings are set in action when the fluid travels.

These nerve terminals convert vibrations into electrical impulses, which travel to the brain via the eighth cranial nerve (auditory nerve). It is made up of little hair cells that border the cochlea. These cells convert vibrations into electrical impulses, which sensory nerves carry to the brain.

Mechanical vibrations are transmitted. Hair cells of the Corti organ convert mechanical sound waves into nerve signals. When the basilar membrane, on which the organ of Corti lies, vibrates, they are activated.

Option(B) Ureter is the correct option.

The ureter is a vital part of the urinary system in humans. It is a muscular tube that connects the kidneys to the urinary bladder. Each human has two ureters, one attached to each kidney, and they play a crucial role in the transportation of urine from the kidneys to the bladder.

The primary function of the ureter is to carry urine that is produced in the kidneys to the urinary bladder for storage before it is eliminated from the body through urination. The ureters accomplish this by using peristalsis, a wave-like muscular contraction, to propel urine along their length.

The ureters have a complex anatomical course. They originate from the renal pelvis, which is the funnel-shaped structure that collects urine from the kidneys. From there, they extend downward, crossing over the brim of the pelvis and passing behind the peritoneum, the membrane lining the abdominal cavity.

The efficient functioning of the ureters is essential for the proper elimination of waste products and maintenance of fluid balance in the body. Any obstruction or abnormality in the ureters can lead to conditions like kidney stones, urinary tract infections, or urinary reflux.

In summary, the ureters are muscular tubes that transport urine from the kidneys to the urinary bladder. They rely on peristaltic contractions to propel urine, and their structure and positioning help ensure unidirectional flow.

The number of hydrogen ions present in 45 mL of concentrated sulphuric acid solution is 4.97 × 10²³ ions.

To calculate the number of hydrogen ions in the acid, we have to calculate the number of moles as follows:

Density = mass ÷ volume

According to this question, concentrated sulphuric acid with molar mass of 98.12 g.mol¹ has a density of 1.5 g/cm³ and is 60% H₂SO4 per mass.

Mass = 1.5g/cm³ × 45cm³ = 67.5grams.

Moles = mass ÷ molar mass

moles = 67.5g ÷ 98.12g/mol = 0.687 moles

If 60% of this quantity contains the acid, then 60/100 × 0.687 = 0.413 moles of acid is present.

There are 2 moles of H+ in sulphiric acid, hence, the no of ions can be calculated as follows:

no of ions = 2 × 0.413 × 6.02 × 10²³ = 4.97 × 10²³ ions.
