If an organism is multicellular, it probably has
A.) Prokaryotic cells
B.) Eukaryotic cells
C.) Cancer cells
D.) All of the above
Answer:
B. Eukaryotic cells
Explanation:
Prokaryotic cells are only seen in unicellular organisms as bacteria and cancer cells are just cells where there has been an error in division or a mutation.
If an organism is multicellular, it probably has - option B.) Eukaryotic cells.
Cells are of mainly two types prokaryotic cells and eukaryotic cells. The main difference between eukaryotic and prokaryotic cells is that:
Eukaryotic cells have a nucleus in which genetic material is stored enclosed by a nuclear membrane.All prokaryotic cells only form single-celled (unicellular) organisms without a true nucleus or membrane-bound structures, examples of prokaryotes are bacteria and archaea. Organisms with eukaryotic cells are called eukaryotes that can be either multicellular such as animals, plants, fungi, and protists, or single-celled as well. So, all multicellular organisms are eukaryotes..Thus, If an organism is multicellular, it probably has - option B.) Eukaryotic cells.

What is protein?
Protein has been defined as the large macromolecules as well as biomolecules that are used to made up of the long chains of the amino acid. There has been various function of the protein such as the DNA replication, speeding up of chemical reaction which helps to maintain the structure of cell.
The main function of the protein has to maintain the structure and function of the organs, repair muscle, and the muscles. Diet contains high protein has been recommended for the purpose of losing weight, reducing fat, or increasing fat.
There are several types of the protein such as the structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.
Therefore, Both protein and carbohydrate molecules tend to form chains. These chains differ in that protein chains are composed of amino acids, and carbohydrate chains are composed of sugars. Thus, option D is correct.

Photosynthesis Takes Place in Chloroplasts. ... The inner membrane surrounds a stroma, which is the site of the carbon chemistry of photosynthesis
sorry if im wrong
Photosynthesis occurs in chloroplast thylakoid membranes. Electron transport chains produce ATP and NADPH. Therefore, option (A) is correct.
What are chloroplasts?Chloroplasts are plastids that are made up of an outer membrane, an inner membrane, grana, and the stroma. These four components make up the chloroplast. The inner membrane encloses a region that is filled with fluid and is known as the stroma. This region includes enzymes that are responsible for light-independent processes that occur during photosynthesis. When this inner membrane is folded inward, it creates linked stacks of disk-like sacs known as thylakoids. These thylakoids are frequently grouped in stacks that are called grana.
The chemical reaction known as photosynthesis, which converts sugar and oxygen from carbon dioxide and sunlight, takes place in chloroplasts, which are found in plant cells.

d.Blue light has a shorter distance between wave crests than orange light.
A. Red light has a longer distance between wave crests than blue light.
Explanation:Make sure u read!!!!
The correct answers are C. Blue light has a longer distance between wave crests than red light, and E. Orange light has a shorter distance between wave crests than violet light.
What is visible light?Visible light waves are a type of electromagnetic radiation that are visible to the human eye. They make up a small portion of the electromagnetic spectrum and have wavelengths that range from about 400 nanometers (nm) to 700 nm. Visible light waves can be separated into colors of the rainbow, including red, orange, yellow, green, blue, indigo, and violet.
Each color of visible light has a unique wavelength and frequency. Red light has the longest wavelength and the lowest frequency, while violet light has the shortest wavelength and the highest frequency. This means that red light has a longer distance between wave crests than violet light, and violet light has a shorter distance between wave crests than red light.

if scientists want to solve an environmental problem they are most likely to use ?
Answer:
Technology
Explanation:
Are most environmental issues local problems or global problems?
How can or will this affect the way we try to solve these issues?
How are environmental issues becoming more complex?
What about the history of environmental studies can inform us about our current environmental issues? Why is it important to understand the past to help solve current and future environmental problems?
Answer:
Most environmental issues are problems on a global scale, these include but are not limited to, global warming, ozone pollution, greenhouse gases and many more issues.
This affects the way we try to solve these issues because if we dont all play a part to help change the way things are going, then they will only get worse. We have to come together as a whole.
Unlike individual efforts, different countries can cooperate and implement legislation which limitates all the countries in the globe,solving environmental issue more efficiently.

What features do we find only in the cells of animals?
What features do we find only in the cells of plants?
Answer:
In bacteria cells, you would find pili (only found in bacteria and archaea) and DNA not contained in a nuclear envelope/nucleus. These are, for the majority, exclusively found in bacteria cells.
In animal cells, you would find lysosomes and centrosomes. These organelles are exclusively found in animal cells.
In plant cells, you would find plastids, such as chloroplasts or amyloplasts. More specifically, chloroplasts are exclusively found in plant cells as they are necessary for photosynthesis to occur.
