Which pair of structures would provide a positive identification of an animal cell under a microscope?

flagellum, lysosome


nucleus, mitochondrion

ribosome, cell wall

chromatin, chloroplast

Answers

Answer 1

flagellum, lysosome: Both of these are found in animal cells, but the real difference is flagellum is ONLY found in animal cells

nucleus, mitochondrion: Both of these are found in Animal cells X

ribosome, cell wall: Cell wall is only in plants X

chromatin, chloroplast: Chloroplast is only found in plant cells X

Answer 2

Explanation:

Firstly cell wall and chloroplasts can only be found in plant cells and will not appear in an animal cell.

Flagellum usually appears in many bacteria (microorganism) and only a few animal cells. Most animal cells do not have flagellum.

However animal cells do have a nucleus which contains important genetic material such as DNA and mitochondrion which creates energy for the cell to use for metabolism inside the cell. (Even though most eukaryote cells have these 2 organelles)

Between the 1st and 2nd options, none of them is exactly correct. But nucleus and mitochondria are more widely found in various types of cells (plants, etc.)

I would choose the 1st option as the best answer here because it is more detailed.

Molecules of DNA are composed of long chains of?

Answers

two long polynucleotide chains

A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together

Molecules of DNA are composed of long chains of nucleotides.

What are nucleotides?

Nucleotides are the building blocks of DNA  and RNA adenine (A), thymine (T), guanosine (G), and Cytosine (C. In RNA, uracil (U) is present instead of thymine.

The pentose sugar is the ribose sugar in RNA and deoxyribose sugar in DNA. In deoxyribose sugar, oxygen is absent from the 3' carbon.

Phosphate groups are attached through the 5-C of pentose sugar by an ester bond. One polynucleotide chain is formed when the phosphate of one nucleotide forms a phosphodiester bond with the sugar of another nucleotide.

A double-stranded structure is formed by base pairing between nucleotides. The adenine binds to thymine by two hydrogen bonds and guanine binds to cytosine by three hydrogen bonds.

Therefore the molecules of DNA are composed of long chains of nucleotides.

Water is an adhesive substance. This means that water particles
A. are attracted to other types of particles.
B. are repelled by other water particles.
C. are attracted to other water particles.
D. are repelled by other types of particles.

Answers

Answer:

A

Explanation:

are attracted to other types of particles.

Adhesion is the term for the attraction of substances between distinct phases. It uses the attraction of water to other polar compounds, as an illustration, hence option a is correct.

What is the characteristic of water?

Cohesion is the tendency of particles to cling together, it uses the attraction of water molecules to one another.

Water has a characteristic called cohesion in which water molecules form bonds with one another. As a result, surface tension develops and raindrops start to form.

Water molecules can interact with other molecules through adhesion, this enables water to adhere to surfaces like windows and other things.

Therefore, water is a strong adhesive that adheres effectively to many different materials, hence option a is correct.

That means we lose around 50 million cells every day. This is a lot of skin cells to replace, making cell division in skin cells is so important. Other cells, like nerve and brain cells, divide much less often.

Skin cells need to divide as you grow. Hair follicle cells divide to produce more hair. Your lining cells (ex: stomach) and intestinal wall cells need to divide to provide new surfaces. Some cells like blood cells, nerve cells, and muscle cells do not divide after some time.

What is the energy source that allows photosynthesis to occur?

Answers

Answer:

[tex]\boxed {\boxed {\sf The \ sun }}[/tex]

Explanation:

Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".

This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.

This process occurs because of the sun. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.

Once assembled, what is the key to a protein's unique function? The manner in which proteins fold is the key to their function

The endoplasmic reticulum is an important  region where protein folding occur. Because proteins need to be appropriately folded into distinct structures, this is an essential biological function.

What is importance of protein folding?

Proteins that are misfolded or are unfolded improperly impart to the pathophysiology of many illnesses.

Protein folding is a highly delicate process that is regulated by a variety of external stimuli, such as temperature, pH, chemicals, molecule crowding, electric and magnetic fields, and temperature.

These elements affect a protein's capacity to fold into the appropriate functional forms.

Identify the natural processes that occur on the earth's surface to make and destroy rocks.

Answers

The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth's surface.

Answer:

You learned about the three rock types: igneous, sedimentary, and metamorphic. You also learned that all of these rocks can change. In fact, any rock can change to become any other type of rock. These changes usually happen very slowly. Some changes happen below Earth’s surface. Some changes happen above ground. These changes are all part of the rock cycle. The rock cycle describes each of the main types of rocks, how they form, and how they change.

The figure below shows how the three main rock types are related to each other (Figure below). The arrows within the circle show how one type of rock may change to rock of another type. These are the processes that change one rock type to another rock type.

Hope you have a great day and if you have a diagram let me know.. I'd love to help :D

Answer:

Part I

At location G, the process of combustion is taking place where hydrocarbon or organic carbon from the fossil fuel is burnt in the presence of oxygen to produce carbon dioxide and water as the products.

CxHy = CO₂ + H₂O

Part II

At point G there is no transformation of energy since during the process of combustion energy will still be stored in form of chemical energy in the bonds of carbon Iv oxide and the water produced during the reaction.

Part III

The process shows recycling of carbon in the carbon cycle. This is because carbon from living organisms is cycled to non living organisms. When plants and animals die and are buried deep in the ground, they are then slowly converted to fossil fuels which contain organic hydrocarbon compounds including petrol, kerosene and other compounds. Then the fossils are used in the industries and undergoes combustion releasing carbon iv oxide which is then released to the atmosphere and used by the plants and animals. The process starts once again.
