Eyepiece magnification(EM) X Objective magnification (OM)= Overall Magnification:
Answer:
I. Overall magnification (TM) = x40
II. Overall magnification (TM) = x100
III. Overall magnification (TM) = x400
IV. Overall magnification (TM) = x1000
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Mathematically, the overall (total) magnification of a microscope is given by the formula;
Overall magnification (TM) = Eyepiece magnification(EM) X Objective magnification (OM).
I. When EM = x10 and OM = x4
TM = EM * OM
TM = x10 * x4
TM = x40
II. When EM = x10 and OM = x10
TM = EM * OM
TM = x10 * x10
TM = x100
III. When EM = x10 and OM = x40
TM = EM * OM
TM = x10 * x40
TM = x400
IV. When EM = x10 and OM = x100
TM = EM * OM
TM = x10 * x100
TM = x1000
Jhich best describe the role of small intestine in digestion?
A. It temporarily stores the food
B. Secrets bile to help in digestion.
C. Helps in the absorption of nutrients from food.
D. It carries food from the mouth to the stomach.
The best option that describes the role of the small intestine in digestion is (C) it helps in the absorption of nutrients from food.
What is small intestine?The small intestine is a vital part of the digestive system, and its main role is to facilitate the absorption of nutrients from the food we eat. After food is partially digested in the stomach, it enters the small intestine, where it is broken down further by enzymes secreted by the pancreas and bile from the liver.
The walls of the small intestine are lined with small finger-like projections called villi, which greatly increase the surface area available for nutrient absorption.
As food passes through the small intestine, nutrients such as carbohydrates, proteins, and fats are absorbed through the villi and into the bloodstream, where they can be transported to the cells throughout the body to be used as energy or for other purposes.
In addition to nutrient absorption, the small intestine also plays a role in the digestion of carbohydrates and proteins, and it helps to regulate the release of digestive enzymes and hormones.
Overall, the small intestine is a crucial component of the digestive system, and its proper functioning is essential for maintaining good health and well-being.

Which statement correctly describes the significance of meiosis during gamete formation?
Answer:
Explanation:
During sexual reproduction, meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.

Identify how Newton's third law of motion was responsible for the astronaut's return to the space station.
Answer:
sorry i cant understand clearly
Explanation:
i hope its help more
Answer: The equipment will "push back" on the astronaut with the same amount of force.
Explanation: Newton's third law of motion can be summed up as "For every action, there is an equal and opposite reaction." This means that when the astronaut applies force to push the object, that object will apply an equal amount of force to the astronaut.

PLS HELP ME THANKS :) write a short paragraph evaluating the different methods of seed dispersal.
Explanation:
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. Dandelion seeds float away in the wind
List the levels of organization of that makeup an organism, starting with an atom and ending with an organism.
Atom, molecule, organelle, cell, tissue, organ, organ system, organism
The levels of organization that makeup an organism are the degrees of increase in complexity of structures, from the atomic level to more complex ones. In this sense, the levels of organization of an organism are:
1. Atom
2. Molecule
3. Macromolecules
4. Cells
5. Tissue
6. Organs
7. System of organs or apparatus
8. Organism
The atom is the smallest fundamental unit of matter, it is made up of subatomic particles: protons, electrons, and neutrons.
Different combinations of similar or different atoms form molecules.
Macromolecules are large molecules, generally formed by polymerization of smaller units called monomers.
The cell is the essential structure for life, which is made up of different combinations of molecules.
Tissues are structures made up of combinations of cells.
Organs are a collection of tissues in a structure with a common function.
Organ systems is the system where organs are related to fulfill a systemic function.
An organism is an individual multicellular living being that has an independent existence, made up of a variety of systems.
Therefore, we can conclude the levels of organization of that makeup an organism are atoms, molecules, Macromolecules, cells, tissues, organs, organ systems and ending with an organism.
