The four major modes of nutrition in prokaryotes are photoautotrophic, chemoautotrophic, photoheterotrophic, and chemoheterotrophic. Their differences, energy source and carbon source are explained below:
WHAT ARE PROKARYOTES?
Prokaryotes are a group of organisms that do not have their genetic material enclosed in a membrane bound NUCLEUS. They include bacteria, archeae etc.METABOLISM IN PROKARYOTES:
All organisms, prokaryotes inclusive, need energy for their metabolic activities. They also need carbon. Hence, based on their carbon and energy source, prokaryotes can be:
Photoautotrophic: These are prokaryotic organisms that use carbon dioxide as their carbon source and light as their energy source. Example iscyanobacteria.
Chemoautotrophic: These are prokaryotic organisms that act on inorganic substances as energy source and use carbon dioxide as carbon source. Example is Nitrosomonas bacteria.Photoheterotrophic: These are prokaryotic organisms that use light as source of energy but obtain carbon from other organisms (organic sources). Examples are heliobacteria, sulfur bacteria.Chemoheterotrophic: These are prokaryotic organisms that act on inorganic substances as energy source but derive their carbon source from organic compounds (other organisms).Learn more: https://brainly.com/question/6103977

What are similarities and differences between insects that go through complete metamorphosis and incomplete metamorphosis?
There are two types of metamorphosis-incomplete and complete.
In incomplete metamorphosis, an adult insect lays an egg. The egg hatches into a nymph, which is like a mini adult. This nymph then grows into an adult. As the nymph grows, it molts several times. Grasshoppers are examples of insects that undergo incomplete metamorphosis.

MARK AS BRAINLIST IF IT IS USEFUL .
Fossil fuels are a non-renewable resource that takes years to form. They are the source of large energy production and provide cost-efficient cheaper energy. Thus, option A is correct.
What are fossil fuels?Fossil fuels are the dead remains that got converted into sediments and over millions of years produced the fuels used to drive energy. They are produced from deposition of the organic matter and are widely used resources for energy.
They are present in the crust of the earth and are a cheaper form of energy than wind and geothermal energy. They are found in the form of coal, petrol, diesel, and other natural gases. They are produced from decaying organic matter.
These fuels are less costly than the alternative form of energy, however, are the reason for increased temperature and climate change. They have added to the greenhouse gases and are major pollutants.
Therefore, option A. fossil fuels are cheaper.

a. a structure that aids in the process of cell division.
b. found in the cytoplasm of eukaryotic cells.
c. a system of tracks used for transport.
d. composed of microtubules and microfilaments.
e. All answers are correct.
Answer: e
Explanation: Cytoskeleton is a microfilaments, intermediate filaments, and microtubules that provide support and movement for eukaryotic cytoplasm.
1. Prokaryotic cytoplasm lacks certain features of eukaryotic cytoplasm, such as cytoskeleton and cytoplasmic streaming.
2. The cytoskeleton provides support and shape to cell.
3. It help in transporting substances through cell.
4. It help in phagocytosis.
5. It help in cytoplasmic streaming that is movement of eukaryotic cytoplasm from one part of cell to another which help distribute nutrients and move the cell over the surface.
6. The study of the numerous interaction between microbes and host cell cytoskeleton is a very intense area of investigation on virulence mechanism.
All answers are correct. Therefore, option (E) is correct.
What is cytoskeleton?The cytoskeleton is a complex network of protein filaments that extends throughout the cytoplasm of eukaryotic cells. It plays a number of important roles in the cell, including providing structural support, helping cells maintain their shape, and assisting in the movement of organelles and other cellular components. The cytoskeleton is also involved in the process of cell division, or mitosis, which is the process by which a single cell divides into two daughter cells.
The cytoskeleton is composed of three types of protein filaments: microtubules, microfilaments, and intermediate filaments. Microtubules are long, thin protein fibers that form a kind of scaffolding within the cell. Microfilaments, which are made of actin proteins, are thinner than microtubules and are involved in muscle contraction and cell movement. Intermediate filaments are thicker than microfilaments and provide structural support to the cell. Together, these three types of protein filaments form a system of tracks that can be used for transport within the cell.

Intravenous (IV) drug administration is one of the routes or methods of administration of drug which involves delivering of the drug directly into the vein. Non-vesicant IV fluids which includes normal saline and many antibiotics are administered through this process. The procedure involves a needle which is usually inserted into a vein in the wrist, elbow, or the back of your hand. The catheter is then pushed over the needle. The needle is removed, and the catheter remains in your vein.
There some complications which are likely to occur during the administration of non-vesicant fluid through IV route. A typical example is IV INFILTRATION. This is defined as the accidental leakage of non-vesicant fluid into the surrounding tissue from the vein. It includes the following sings and symptoms:
Redness around the site.Swelling, puffy or hard skin around the site.Blanching (that is, lighter skin around the IV site)Pain or tenderness around the site.
