Here is an image of the mitochondria. Mitochondria numbers can differ between cell types based on the function of the cell. Which of these cells would contain the highest number of mitochondria?
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.

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.

Which system is the digestive system least connected to?
A)Nervous
B) Integumentary
C) Circulatory
D) Excretory
Answers
The system that the digestive system is least connected to is the Integumentary which is option B.
In the body, food is broken down into simple, soluble and diffusible substances by mechanical and chemical means through the digestive system.
The alimentary tract of the digestive system is connected to the nervous system. This is because the autonomic nervous system supplies nerves to the alimentary tract and this leads to:
Either increase or decrease of muscular activity, especially peristalsis.Either increase or decrease of glandular secretion.The circulatory system is connected to the digestive system through blood supply from the arteries and blood drainage through the veins.
The excretory system is connected to the digestive system. this true because the food substances that have been eaten but cannot be digested and absorbed are excreted from the alimentary canal as faeces by by the process of defecation.
The Integumentary system in an external part of the body which is involves protection of the body. it dosen't play any role in the digestive system and so its least connected to it.
