What is Microscope?Microscope: a device that magnifies small objects, giving the user a close-up view of minuscule structures at a scale suitable for observation and analysis.
Even though optical microscopes are the focus of this article, an image can also be magnified by a variety of different wave types, such as acoustic, X-ray, or electron beams, and is then captured using direct or digital imaging, or a combination of these techniques.
The magnifying power of a microscope is a dimensionless ratio that expresses how often the thing under examination seems to be magnified.
Therefore, All organisms come from pre-existing cells that divide.

Which of the following describes methyl jasmonate?
a gas emitted by cabbage plants when injured
a byproduct of the process of photosynthesis
a mycorrhizal fungus
an element of the phloem
Answer:
The correct answer is - a gas emitted by cabbage plants when injured.
Explanation:
Methyl jasmonate is a gas that is released or emitted by the leaves of the injured cabbage or when any insects eat it. It is an organic compound used as a defense mechanism by plants such as cabbage.
It is a very volatile organic compound. It is also found in flowers of Jasminum grandiflorum. It plays role in other pathways such as root growth, flowering, and fruit ripening and others.

Explanation:
A cell is simply defined as the structural and functional unit of an organism. It is made up of highly organized physical structures called intracellular organelles. These organelles includes:
• Ribosome
• Lysosomes
• Smooth Endoplasmic reticulum
• Plasma membrane
A type of cellular motion called ciliary movement, is a whip-like movement of CILIA on the surface of cells takes place in the respiratory airways of human.
The cytoplasm is filled with both intracellular fluid and organelles while the cytosol contains mainly dissolved proteins, electrolyte and glucose ( intracellular fluid).

Which statement correctly describes the relationship between air temperature and air pressure?
1. Warm air rises, creating an area of low pressure.
2. Cool air sinks, creating an area of low pressure.
3. Warm air sinks, creating an area of low pressure
4. Cool air rises creating an area of low pressure.
Answer:
jayfeather friend me
Explanation:
Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure.

The six modes of disease transmission shown in the Model 2 are
1. Airborne
What is airborne?The Airborne transmission can be caused by coughing, sneezing where
water droplets carry the disease causing organisms.
Example: flu, tuberculosis, etc.,
2. Food borne or waterborne
The pathogen is transmitted by the consumption of contaminated
food or water
Eg: cholera, botunilsm, etc.,
3. Vector
The vector such as insects or animals can act as vectors by carrying disease causing malaria, dengue.
4. Blood borne
The disease is caused by the transmission of blood or contact of
injured cuts or incisions.
Example: hepatitis, AIDS, etc
5. Contact
The disease is caused by the person to person direct contact of skin to skin such as leprosy, skin and eye infections, fungal infections, etc.,

Which of the following would show the Dominant Genotype? (Choose all that apply)
Answer:

Explanation:
Look at the following diagram of the carbon cycle.An image of carbon cycle is shown. The sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. An arrow is shown from the sun towards the left tree marked A. The sun is marked B. There is an arrow from the air above the clouds, marked C, towards the left tree. An arrow from a location close to the ground marked D points towards Dead Organisms, which is a label under the animal. An arrow marked E points from the right tree straight up to the clouds. An arrow marked F points from the animal straight up to the clouds. An arrow marked G points from the factory towards the air above the clouds, C. There is an arrow pointing from the air to the lake labeled Carbonates in Water, an arrow pointing down from dead organisms to Fossils and Fossil Fuels, and an arrow from Fossils to the factory.Which of the following facts is best represented by the arrow pointing from G to C? The chemical energy present in fossil fuels is used to create new forms of energy used for photosynthesis. Energy is conserved because the chemical energy present in fossil fuels is used up completely during burning. The mechanical energy produced on burning fossil fuels is transformed into chemical energy stored in carbon dioxide. Energy is conserved because the mechanical energy produced on burning fossil fuels is less than the chemical energy formed.

What are 4 different protists and what makes them special
Answer:
Amoebalike protists, flagellates, ciliates, and spore-forming protists.
Explanation:
Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.
