and
What macromolecules can be found in plant cells
Answer:
ANIMALS: There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell's mass.
PLANTS: The three main classes of macromolecules found in plants are thus proteins, polysaccharides and nucleic acids. However, mixed polymers are also known. such as the glycoproteins, which contain both sugars and amino acids in covalent linkage.
The macromolecules found in animal cells are carbohydrates, proteins, lipids, nucleic acids, and water. Each of these macromolecules has specific functions in the body of kingdom Animalia.
What are Macromolecules?Macromolecules may be defined as a molecule that contains a very large number of atoms that are held together by specific bonds.
The macromolecules found in animal cells are polysaccharides, proteins, nucleic acids, water, and some types of mixed polymers.
All such macromolecules perform specific functions in the structure of kingdom Plantae and meet the need for metabolic activities.
Therefore, it is well described above.

What is the MAIN type of energy that is produced during cellular respiration?
Glucose
O ATP- Adenine Triphosphate
O Water
Light
Answer:
ATP- Adenine Triphosphate
Explanation
:In cellular respiration, energy is obtained by oxidizing an organic molecule, usually glucose, releasing energy. Part of that energy is stored as ATP (adenosine triphosphate) molecules, and part is released as heat.

Metalloids that can conduct electricity at high temperatures are
called
Metalloids that can conduct electricity at high temperatures are called semiconductors.
Semiconductors are a group of elements that have properties intermediate between those of metals and nonmetals. They have some characteristics of metals, such as being able to conduct electricity, but also some characteristics of nonmetals, such as having lower conductivity than metals.
At low temperatures, semiconductors have very low conductivity. However, at high temperatures, they can conduct electricity more effectively. This is because at higher temperatures, the thermal energy causes more electrons to break free from their atoms and become available for conduction.
One example of a semiconductor that can conduct electricity at high temperatures is silicon. Silicon is widely used in electronic devices, such as computer chips and solar cells, due to its ability to control and amplify electrical signals.
In summary, metalloids that can conduct electricity at high temperatures are known as semiconductors. They have properties intermediate between metals and nonmetals and can conduct electricity more effectively at high temperatures. Silicon is an example of a semiconductor commonly used in electronic devices.

1) State whether plants perform cellular respiration and explain why or why not.
2)Explain which cell would likely contain more mitochondria, a muscle cell or a skin cell. Use your knowledge of energy; mitochondria and their function to support your answer.
Answer:
1) plants use photosynthesis to produce glucose, but the use cellular respiration to release energy from glucose so yes they do perform cellular respiration
2) a muscle cell because mitochondria is the site of cellular respiration (releasing energy from glucose) and they need more energy for muscle contraction

Answer: binary fission, form of sexual reproduction in which paramecia and some prokaryotes exchange genetic information. I THINK this is right!
Answer:
The answer is binary fission.
Explanation:
Binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.

Students planted the same type and number of seeds in pots A and B. The amount and type of soil in both pots were also the same. Each plant received the same amount of water each week. Pot A was placed by a sunny window. Pot B was placed in a closet. After four weeks, the students observed the plants in both pots. The plants in pot A were green with thick stems. The plants in pot B were yellow with thin stems. Which statement best explains why the plants in pot A were different from the plants in pot B?
Answer:
C) Pot A received more sunlight than pot B.
Explanation:
Seeds or plants require some very important factor to grow that include carbon-dioxide, water and sunlight to undergo the process of photosynthesis.
Photosynthesis is the process by which plants make their own food by utilizing carbon-dioxide and water in the presence of sunlight and releases oxygen and energy.
In the given example, both the plants received equal amount of water and soil but the difference is in the position of the plant, in which plant A was placed by a sunny window from where plant have undergoes the photosynthesis process and grew with green with thick stems. while plant B was placed in a closet where no sunlight was present and the plant grew with yellow with thin stems.
Hence, the correct answer is "C) Pot A received more sunlight than pot B. "
Answer:
Answer: C) Pot A received more sunlight than pot B
Explanation:
Here's why: Pot A received more sunlight than pot B is correct. Plants need sunlight in order to make chlorophyll. Chlorophyll is the chemical that makes plants green.

This stadium can hold 100,000, or 1x10, people. The
number of atoms in a grain of iron is about 1x 1016,
Would you need 1 x 10° or 1 x 10' stadiums to hold
the same number of people as the number of atoms in
a grain of iron? Explain your answer,
Answer:
1 x 10^13 stadiums will be needed in this scenario
Explanation:
We are told that
1 stadium holds = 1 × 10^5 people and
Number of iron atoms = 1 × 10^18 atoms
If the stadium carries an equivalent number of atoms as that of people.
We can infer that 1 stadium will carry 1 × 10^5 atoms.
The calculation to determine the number of stadiums would then be 1 × 10^18 divided by 10^5 atoms/stadium which was gotten by dividing the total number of atoms by the number of atoms per stadium.
Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium
= 1 × 10^13 Stadiums
This means that 1 × 10^18 atoms would occupy 1 × 10^13 stadiums

These always contain DNA as the main genetic material
A. Virus
B. Both
C. Cells
Answer:
C
Explanation:
The one that always contain DNA as the main genetic material is cell nucleus. The correct option is C.
What is genetic material?The genetic material is the molecule that contains genes and is passed down from parents to children. It contains instructions for the growth and function of living organisms.
DNA and RNA are the two main types of genetic material. DNA is stored in the nucleus of eukaryotic cells, which have a nucleus and membrane-bound organelles, and is wrapped around round proteins called histones. DNA is ended up finding in the cytoplasm of prokaryotic cells.
A virus is composed of a core of genetic material surrounded by a protein-based protective coat called a capsid.
Viruses have either RNA or DNA as their genetic material, but neither. Single-stranded or double-stranded nucleic acid
Thus, the correct option is C.
