Many types of microscopes exist, allowing different levels of magnification and producing different types of images

Answer: 4) white blood cells

Explanation:

The bleeding from a small cut soon stops due to the release of platelets. Hence, option 1 is the correct answer. These are cell fragments of megakaryocytes.

When there is a cut, blood comes out of that organ. To prevent blood loss, the body has certain mechanisms. This mechanism is called blood clotting.

In the blood, different cells are present. Red blood cells (RBC), white blood cells (WBC), and megakaryocytes are present in the blood. The red blood cells supply oxygen to the different tissues. It consists of hemoglobin. The white blood cells protect the body from pathogens. Eosinophils, neutrophils, basophils, monocytes, etc. are white blood cells ( WBC) 

Megakaryocytes are the cells that form platelets. These platelets are cell fragments of megakaryocytes. When a cut occurs, these platelets come to the site along with other clotting factors such as fibrinogen to form a network-like structure. Due to this network, the blood cells can't come out, and blood loss stops.

Hence, option 1 is the correct answer as platelets prevents the blood loss. Other options are incorrect.

Answer:

They should be placed in the small and large intestine.

Explanation:

The small and large intestine is the part of our digestive system that absorbs the nutrients from food. Previous to this step, the food went through the mouth, the esophagus, and the stomach. In those places, it was processed so that the intestines could absorb the nutrients from the food easily/

For nutrients to be absorbed, they should be in stretch contact with the intestines' walls where the smallest arteries, which are called capillaries, are present and will take the nutrients into its interior where the blood is. Also, the intestines have lymphatic vessels. These ones will protect our body from any antigen since they are part of our immune system.

Answer:

True

Explanation:

Tree roots that grow into crevices and small animals that burrow can cause physical weathering.

Answer: Plankton

Explanation:

Plankton are small organisms that exist in water and are too weak to swim against the currents of the ocean and the seas. This leads to them going wherever the currents take them. Plankton can be either plants or animals.

Of the organisms listed, they are on the lowest trophic level and provide a source of food to other organisms of different sizes ranging from krill to whales.

Answer:

b) contains hereditary information and controls most of heredity and cell processes

it contains and protects DNA

Explanation:

The statement that best describes the function of the nucleus is that it contains hereditary information and controls most of the heredity and cell processes.  

Cells are recognized as the building blocks that make up organisms. These cells are further made up of several structures that are well defined. Those well-defined forms of structures are referred to as organelles. The Endoplasmic reticulum, Mitochondria, and Nucleus are some of the examples of cells’ organelles.  

The function and features of the nucleus are listed as follows:  

Thus, we can conclude that the statement “contains hereditary information and controls most of the heredity and cell processes” best explains the function of the nucleus.

Answer:

The answer is A - Convergent boundary resulting in earthquakes and volcanic activity

Explanation:

In map, Convergent boundary resulting in earthquakes and volcanic activity.

A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.

The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone. A convergent boundary is an area on Earth where two or more lithospheric plates collide.

Another form of convergent boundary is a collision where two continental plates meet head-on. Since neither plate is stronger than the other, they crumple and are pushed up.

Based on the information in the graph Australia's population is currently growing the least.

Australia's population almost doubled in the past 50 years, from 13.1 million in 1971 to 25.7 million in 2021. But more remarkable is that this record population growth has exceeded all forecasts.

Australia has an average population density of 3.4 persons per square kilometre of total land area, which makes it one of the most sparsely populated countries in the world. This is generally attributed to the semi-arid and desert geography of much of the interior of the country.

Answer:

Coal:

Coal is primarily used as fuel to generate electric power

Petroleum:

heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials

Natural gas:

heating, cooking, and electricity generation.

it all end up in the atmosphere

Explanation:

The coal is burned and the heat given off is used to convert water into steam, which drives a turbine.

petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria.

Like oil, natural gas is a product of decomposed organic matter, typically from ancient marine microorganisms, deposited over the past 550 million years. This organic material mixed with mud, silt, and sand on the sea floor, gradually becoming buried over time.

Coal and natural gas are burned in power plants to boil water. Steam from boiling water converts turbines into electricity. Carbon dioxide from burning fuel is released into the atmosphere.

This is about description of fossil fuels which are simply fuels that are formed from natural processes.

       The uses and end products of fossil fuels are talked about in the explanations below;

          ii) When coal is burnt, it produces a very high heat. This heat is so high that it converts water into high-pressure steam. What drives a turbine is a high pressure steam and this drive makes the turbine to produce electricity.

           II) when petroleum is burnt to create energy, it produces high amount of carbon dioxide and other toxic gases into the atmosphere that can cause greenhouse effect.

           II) When it undergoes combustion is produces large amount of carbon dioxide and nitrogen oxides into the atmosphere.

Answer:

Explanation:

The difference between DNA and RNA is.....

DNA = Double-stranded

RNA = Singer-stranded

DNA = The sugar moiety is deoxy ribose

RNA = Ribose is the main sugar

DNA = Thymine is always there, but uracil is never found

RNA = Pyrimidine components differ. Thymine is never found

DNA = It follows Chargaffs rule (since it's double stranded)

RNA = Doesn't follow Chargaffs rule (since it's single stranded)

Answer: Rearranged

Explanation:

In chemical reactions, atoms cannot be destroyed, created, or neutralized, and that is why the only correct answer, in this case, is that atoms in chemical reactions can be rearranged.

They aren't destroyed and they can never be destroyed and also they cannot be created because of the law of conservation of energy in chemical reactions.

This law is considering that ''A matter cannot be created nor destroyed, it can only be formed in one way or the other.''
