Explanation becasue Bacteria (singular: bacterium) are a major group of living organisms. Most are microscopic and unicellular, with a relatively simple cell structure lacking a cell nucleus, and organelles such as mitochondria and chloroplasts.Bacteria are the most abundant of all organisms.
Place the phases of a stem cell into the correct order.
A.differentiation, mitosis, specialization
B.gene expression, differentiation, mitosis
C.mitosis, gene expression, differentiation
D.mitosis, specialization, gene expression
Answer:
C. Mitosis, Gene expression, differentiation
Explanation:
Stem cells are referred to as undifferentiated cells which has the ability to develop into new specialized cells via cellular differentiation. The stem cell initially undergoes MITOTIC division to form new stem cells.
This stem cells then undergo GENE EXPRESSION by turning off some genes and turning on some in order to specialize the cell type. After this, the cell becomes DIFFERENTIATED i.e becomes another type of cell
Place the phases of a stem cell into the correct order.
The correct order would be mitosis, gene expression and then differentiation.
Stem cells can be defined as undifferentiated cells that possesses the ability to develop into many other different cells of the body. Before a stem cell becomes differentiated, the stem cell undergoes growth, mitosis and then information from the gene (DNA) in the cell will be needed to determine the type of cell it will become and be expressed before differentiating and becoming specialized to give rise to a particular type of cell.

in your own words, explain why osmosis is really just a special case of facilitated diffusion
Answer: It describes water molecules moving across a membrane, which allows the water molecules to pass in and out freely, but forbids the motion of other molecules.
Explanation:
A in Biology class last year.
Osmosis is really just a special case of facilitated diffusion because it
doesn't permit the movement of some molecules.
Osmosis can be defined as the movement of solvent molecules such as
water from a region of higher concentration to a region of lower
concentration through a semi-permeable membrane.
Osmosis is however a special case of facilitated diffusion because it permits
the movement of water molecules and inhibits the movement of other
molecules such as sugar etc.

Answer:
An ionic bond is one formed between two ions with opposing charges. In covalent bonding, molecules are formed by the constituent atoms sharing electrons so they both have full valence (outer) shells, but some electrons occupy the outer shells of both elements at the same time.
The main components of the plasma membrane contain hydrophobic and hydrophilic regions that give the membrane selective permeability. Which of the following is the
main component that creates the hydrophobic and hydrophilic regions? (3 points)
a. Cholesterol molecules creating membrane fluidity
b. Carbohydrates for cell recognition
c. Glycolipids containing hydrophobic lipid portion
d. Phospholipids containing hydrophobic fatty acids tails
Answer:
The main components that creates the hydrophobic and hydrophilic regions of the plasma membrane are phospholipids containing hydrophobic fatty acids tails.
Explanation:
Phospholipids are the main component of the cell membrane —lipid bilayer— and responsible for its selective permeability. Each phospholipid is composed of one glycerol molecule, which forms the head, and two fatty acid tails, plus one phosphate molecule.
In the lipid bilayer, the phospholipid heads are oriented towards the surface, while the tails are located inside, allowing interaction with both polar and apolar molecules.
The hydrophilic regions of the membranes are in contact with the liquids of the extracellular and intracellular spaces, while the hydrophobic region is inside the membrane, limiting the passage of polar molecules or ions.
The other options are not correct because:
a. Cholesterol molecules are part of the membrane, but are not responsible for the hydrophobic and hydrophilic regions.
b. Carbohydrates for cell recognition do not determine membrane permeability.
c. Glycolipids, like integral proteins, are part of the membrane, but do not determine the polarity of the regions.
What can be used to measure the rate of photosynthesis
Answer:
the answer it at the bottom
Explanation:
Uptake of CO2 by plants: Since CO2 is needed for photosynthesis, measuring how much of it is taken up by the plants gives us information on how much of photosynthesis is happening.
Release of O2: The amount of O2 produced during photosynthesis can be measured.

Group of answer choices The bacteria would grow by itself outside the person. The virus would have DNA. The bacteria would make another person sick. The virus would have proteins.
Answer:
The bacteria would grow by itself outside the person
Explanation:
The bacteria would grow by itself outside the person. - this is correct. Bacteria are independent organisms that do not need other cells to replicate. However, viruses require the cell's machinery to divide and cannot survive independently
The virus would have DNA. - Both bacteria and viruses have DNA (or the virus might have RNA)
The bacteria would make another person sick. - Both viruses and bacteria could make another person sick
The virus would have proteins - Both viruses and bacteria have proteins

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.
