Answer:
Osteoclasts.
Explanation:
Osteoclasts may be defined as the cells that helps in the breakdown of the bone tissue. Osteoclast plays an important role in the maintenance of the bone structure.
Osteoclasts cells are found in the small depression of the endosoteal surface. This is also known as Howship's lacunae. They shows the foamy appearance in the cell. The osteoclast can form the specialized cell membrane known as ruffle border.
Thus, the correct answer is option (B).
The main job of DNA is to store and transmit genetic information and direct protein production.
The main job of DNA is to store and transmit genetic information. It contains the instructions for building and maintaining an organism. DNA directs the production of proteins, which carry out many functions in the body, such as regulating cell processes, transporting molecules, and providing structure to cells and tissues.

Answer:
The organelle responsible for converting energy from food into a form the cell can use is the mitochondrion.
The organelle responsible for converting energy from food into a form the cell can use is the mitochondrion.
Mitochondria are often referred to as the "powerhouses" of the cell because they produce the energy currency of the cell, called adenosine triphosphate (ATP). This process is called cellular respiration.
Here's how the mitochondria convert energy from food into ATP:
1. The process starts in the cytoplasm of the cell, where glucose molecules are broken down through a process called glycolysis. This step produces a small amount of ATP.
2. The remaining breakdown products from glycolysis are transported into the mitochondria.
3. Inside the mitochondria, these products undergo further breakdown through a series of chemical reactions in a process called the Krebs cycle, also known as the citric acid cycle. This step releases carbon dioxide and transfers energy-rich electrons to carrier molecules.
4. The carrier molecules transfer the electrons to the electron transport chain, located in the inner membrane of the mitochondria. This chain consists of a series of protein complexes that pass the electrons along, releasing energy in the process.
5. As the electrons move through the electron transport chain, the energy released is used to pump protons (hydrogen ions) from the inner compartment of the mitochondria to the outer compartment, creating an electrochemical gradient.
6. The electrochemical gradient drives the synthesis of ATP through a process called oxidative phosphorylation. ATP synthase, an enzyme embedded in the inner membrane, uses the energy from the electrochemical gradient to convert adenosine diphosphate (ADP) and inorganic phosphate (Pi) into ATP.
Overall, the mitochondria play a crucial role in converting the energy stored in food molecules into ATP, which the cell can then use for various cellular processes.
Answer:
The correct option is;
The number of adenine bases will be equal to the number of thymine bases
Explanation:
The four chemical bases that make up the DNA code are adenine (A), guanine (G), thymine (T), and cytosine (C) which are arranged based on a specif organism such that they represent the information regarding the building of the organism
The chemical bases of the DNA are found in pairs consisting of two chemical bases which are then known as base pairs. The possible base pairs are;
Adenine (A) pairing with thymine (T)
Cytosine (C) pairing with Guanine (G)
Therefore, the forensic scientist should expect to find that the number of adenine bases will be equal to the number of thymine bases.
Since the scientist was trying to find out the number of adenine bases in the DNA sample, assumption that the number of adenine would be equal to the number thymine would help.
According to the base-pairing rule of Chargaff, adenine always pairs with thymine while guanine always pairs with cytosine.
Going by this rule, we can say that the number of adenine must be equal to the number of thymine while the number of guanine must be equal to the number of cytosine in any DNA.

Answer:
frictional
Explanation:
This scenario follows Newton's third law of motion which alludes to the fact that for every force or action exerted by a person on a body there is an equal and opposite reaction exerted back.
Because there is a limited frictional force (a force exerted by an object when an object moves across it) between
Here, the paddle helps the boatman apply a force on the water, resulting in the opposite amount of force been sent back; pushing the boat forward.
