For prokaryotic cells, the cell wall is a tough, fibrous layer that protects the cell and gives it shape and rigidity.
Prokaryotic cells are found in the domain(s) Bacteria and Archaea.
True: Prokaryotic cells have nucleoids and eukaryotic cells have nuclei.
A prokaryotic cell is distinct from a eukaryotic cell because a prokaryotic cell lacks _a nucleus_.
There is only _1_ eukaryotic domain, it is Eukarya.
Describe what happened when the Paramecium populations were mixed in the same test tube.
Answer:
When grown individually in the laboratory, they both thrive. But when they are placed together in the same test tube (habitat), P. aurelia outcompetes P. caudatum for food, leading to the latter's eventual extinction.

Which of the following best describes how amino acids affect the tertiary structure of a protein
Answer:
B. The interactions of the different R group with other R groups and with their environment determine the tertiary structure of the protein
Explanation:
Protein is one of the four major biomolecules in living systems. Structurally, proteins consists of four levels namely: primary, secondary, tertiary and quartenary. The primary structure constitutes the AMINO ACIDS monomer that makes up the protein.
According to this question, the tertiary structure of the protein is formed as a result of the interaction of different R groups with one another and their environment. The R group is one of the four parts of the amino acid structure which is different for all amino acids.
These R groups interact in such a way that forms different bonds such as hydrogen bonds, disulphide bridges, hydrophobic & hydrophilic interactions etc, which leads to the tertiary structure of proteins (three-dimensional shape).
Answer:
B. The interactions of the different R -groups with other R -groups and with their environment determine the tertiary structure of the protein.

The main difference between the water cycle and the other chemical cycles is that water
never changes its structural form (H2O) .
is much slower than the other cycles.
creates completely new substances.
is made from matter that has been here since the world was formed.
Answer:
The answer is A.
Explanation:
Other cycles change their structural form often, but water does not change it's structural form in the water cycle, which is H2O so that is one main difference between the water cycle and oither checmical cycles. So, your answer is A.
The main difference between the water cycle and the other chemical cycles is that water never changes its structural form (H2O). Thus, the correct option for this question is A.
What is the water cycle?The water cycle may be defined as a type of biogeochemical cycle that significantly involves the gradual and continuous movement of water and its derivative products within the Earth and atmosphere.
The water cycle remarkably consists of three major processes. They are as follows:
Evaporation: a process through which a liquid converts into gas.Condensation: a process through which gas converts into liquid.Precipitation: a process through which liquid water falls on the earth's surface.The most important concept of the water cycle is that the structural form of water remains constant and the same throughout the process. This property of water differs from other chemical cycles because such cycles involve the alteration in their fundamental component.
Therefore, water never changes its structural form (H2O) is the main difference between the water cycle and the other chemical cycles. Thus, the correct option for this question is A.

Explain whether the top or bottom layers would be the oldest layer of sedimentary rock.
explain your answer.
Answer:
Because sedimentary rock forms in layers, the oldest layer of undisturbed sedimentary rock will be on the bottom and the youngest on top. If the rock layers are bent, they may no longer be in order from oldest to youngest.
The bottom layer would be the oldest layer of sedimentary rock as sediments deposited earlier will be present at the bottom.
What are sedimentary rocks?They are the types of rocks which are formed as a result of accumulation of minerals or organic particles at the surface of the earth.Sedimentation is the name given to a collective process which cause the particles to settle.
The study of sedimentary rocks is useful in civil engineering and as important sources of coal, fossil fuels and ores.The color of sedimentary rock is often determined by iron content and sometimes due to the presence of organic matter.
They are classified based on origin in to 4 types which are clastic, biochemical ,chemical and other sedimentary rocks.While based on composition they are classified as siliciclastic,carbonate ,evaporite,organic rich,siliceous ,iron-rich and phosphatic sedimentary rocks.

Here is an image of the mitochondria. Mitochondria numbers can differ between cell types based on the function of the cell. Which of these cells would contain the highest number of mitochondria?
Answer:
Muscle cells
Explanation:
Muscle cell have highest number of mitochondria. Thus, option C is correct.
What is mitochondria?
Mitochondria are the power house of the cell, membrane-bound organelles present in the cytoplasm of both plant and animal cell.
It produces adenosine triphosphate (ATP) by breaking down of nutrients. Cellular respiration also occur in mitochondria.
Structurally it comprises three parts such as an outer membrane, an inner membrane, and matrix part which is a gel like structure.
The outer membrane separated by the intermembrane space from the inner membrane and it is composed of proteins and phospholipid layers
The outer membrane has a large number of special proteins called as porins.
It is also involved in regulation of the metabolic activity, promotion of cell growth, multiplication, detoxifying ammonia, apoptosis, make various hormones like testosterone and oestrogen, cellular differentiation, cell signalling, cell senescence, cell cycle control.

Which system is the digestive system least connected to?
A)Nervous
B) Integumentary
C) Circulatory
D) Excretory
The system that the digestive system is least connected to is the Integumentary which is option B.
In the body, food is broken down into simple, soluble and diffusible substances by mechanical and chemical means through the digestive system.
The alimentary tract of the digestive system is connected to the nervous system. This is because the autonomic nervous system supplies nerves to the alimentary tract and this leads to:
Either increase or decrease of muscular activity, especially peristalsis.Either increase or decrease of glandular secretion.The circulatory system is connected to the digestive system through blood supply from the arteries and blood drainage through the veins.
The excretory system is connected to the digestive system. this true because the food substances that have been eaten but cannot be digested and absorbed are excreted from the alimentary canal as faeces by by the process of defecation.
The Integumentary system in an external part of the body which is involves protection of the body. it dosen't play any role in the digestive system and so its least connected to it.

O Herbivores are able to absorb nutrients more efficiently.
o Carnivores are more physiologically advanced than herbivores.
Answer:
Meat is easier to digest than plant materials

If 10 cells undergo the cellular process of meiosis, how many daughter cells will result after Telophase II?
a. 25
b. 5
c. 10
d. 40
Which of the following completes the sentence below by describing an important result of meiosis?
A single cell divides into ___________ daughter cells.
2 identical
2 unique
4 unique
4 identical
A.4 identical
B.4 unique
C. 2 unique
D. 2 identical
Answer:
d. 40, B.4 unique
Explanation:
If 10 cells underwent meiosis, the result would be 40 daughter cells. This is because a cell that goes through meiosis goes through two divisions resulting in 4 daughter cells. This is because cells that undergo meiosis are gametes so they need to have half the number of chromosomes as the cells that go through mitosis.
The resulting daughter cells are unique, unlike the cells that go through mitosis. This is because the chromosomes in the cells experience something called crossing over during Metaphase I. Crossing over is when the chromosomes can swap pieces of DNA when next to each other. Cells in mitosis don't go through crossing over and are therefore identical.
