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.,
6. Seˣual
The disease is seˣually transmitted are AIDS, gonorrhea, syphilis.

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.

hich statement is a correct description of the processes of respiration and transpiration in a plant?
Question 6 options:
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Transpiration is when the plant pulls water into its roots. Respiration is when the plant breathes.
Transpiration is when the plant grows over time. Respiration is when the plant breaks down the sugar in its roots.
Transpiration is when the plant produces buds. Respiration is when the plant dies.
Answer:
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Explanation:
Transpiration and respiration are both processes carried out by plants. Transpiration is the process by which plants lose water via a structure in their leaves called STOMATA. When plants open their stomata for gaseous exchange i.e. take in CO2 or give out O2, they lose water vapor in the process in a process called TRANSPIRATION.
Contrarily, RESPIRATION is a cellular process in which the cells of a plant breakdown sugar molecules (glucose) in order to release energy (ATP) in the process. Respiration equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.

Transpiration and respiration are both processes carried out by plants. Transpiration is the process by which plants lose water via a structure in their leaves called STOMATA.

Which one of these situations would have higher density water?
Question options:
Water at the equator
Lower temperature water
Water with a lower salt content
Water near where a river enters the ocean
A higher density water will be obtained in lower temperature water.
What is density?Density is the fluid property that describes the amount of solutes that dissolves in a given volume of the fluid.
Density of a fluid is calculated by taking the ratio of mass to volume of the fluid.
[tex]\rho = \frac{m}{v}[/tex]
where;
m is the mass of the waterv is the volume of the waterWhen the temperature of the water is low, more mass of the water is obtained while a high temperature evaporates the liquid.
Thus, a higher density water will be obtained in lower temperature water.

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.

Some Prokaryotic organisms are Bacteria, Archaea and E.Coli and Some Eukaryotic organisms are mushrooms, dogs and lizard.
What is the difference between prokaryotic and eukaryotic cells?
Prokaryotic cells are cells without a nucleus. Eukaryotic cells are cells that contain a nucleus. Eukaryotic cells have other organelles besides the nucleus. The only organelles in a prokaryotic cell are ribosomes.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
Eukaryotic cells are cells containing membrane-bound organelles and are the basis for both unicellular and multicellular organisms. In contrast, prokaryotic cells do not have any membrane-bound organelles and are always part of unicellular organisms.

1. In what layer was the first rock formed?
Answer: Bottom layer of rock
Explanation:
The bottom layer is the layer of the deposition of the sediments in which sedimentation and cementation occurs to form the rocks. These rocks are formed at the lowest horizon of the soil profile. These rocks are also called bedrocks. The layer present above the rock are younger and the layer at the top is the youngest layer. The older layer at the bottom and the younger layer at the top. This phenomena is called law of superimposition.

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.
