in cell A, what is the structure labeled X?
Answers
Answer:
Yo i dont know but when someone does please help me bro
Explanation:
In cell A, the structure labeled X is a centriole.
Centrioles are cylindrical organelles found in animal cells, usually existing in pairs called the centrosome. They play a crucial role in cell division by organizing and forming the spindle fibers during the process of mitosis and meiosis.
Centrioles are involved in the separation of chromosomes, ensuring that each daughter cell receives the correct number of chromosomes.
Additionally, centrioles are essential for the organization of microtubules in the cytoskeleton, which provides structural support and maintains cell shape.
Their function in cell division and cellular organization makes centrioles vital components of animal cells.

Explain whether the top or bottom layers would be the oldest layer of sedimentary rock.
explain your answer.
Answers
Answer:
Because sedimentary rock forms in layers, the oldest layer of undisturbed sedimentary rock will be on the bottom and the youngest on top. If the rock layers are bent, they may no longer be in order from oldest to youngest.
The bottom layer would be the oldest layer of sedimentary rock as sediments deposited earlier will be present at the bottom.
What are sedimentary rocks?They are the types of rocks which are formed as a result of accumulation of minerals or organic particles at the surface of the earth.Sedimentation is the name given to a collective process which cause the particles to settle.
The study of sedimentary rocks is useful in civil engineering and as important sources of coal, fossil fuels and ores.The color of sedimentary rock is often determined by iron content and sometimes due to the presence of organic matter.
They are classified based on origin in to 4 types which are clastic, biochemical ,chemical and other sedimentary rocks.While based on composition they are classified as siliciclastic,carbonate ,evaporite,organic rich,siliceous ,iron-rich and phosphatic sedimentary rocks.

Answers
Answer:
Muscle cells
Explanation:
Muscle cell have highest number of mitochondria. Thus, option C is correct.
What is mitochondria?
Mitochondria are the power house of the cell, membrane-bound organelles present in the cytoplasm of both plant and animal cell.
It produces adenosine triphosphate (ATP) by breaking down of nutrients. Cellular respiration also occur in mitochondria.
Structurally it comprises three parts such as an outer membrane, an inner membrane, and matrix part which is a gel like structure.
The outer membrane separated by the intermembrane space from the inner membrane and it is composed of proteins and phospholipid layers
The outer membrane has a large number of special proteins called as porins.
It is also involved in regulation of the metabolic activity, promotion of cell growth, multiplication, detoxifying ammonia, apoptosis, make various hormones like testosterone and oestrogen, cellular differentiation, cell signalling, cell senescence, cell cycle control.
