Answer: The generally accepted parts of modern cell theory include: ... All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells.
Explanation:
To demonstrate that all cells come from pre-existing cells, you should: Observe a bacterium performing binary fission to form clones of itself.
A cell can be defined as the basic functional, structural and smallest unit of life which is found in all living organisms.
According to cell theory, the following statements are true about cells;
All living organisms comprises small structural units called cells.A cell is the fundamental (basic), functional unit of life.Every living organism is made up of one or more cells: unicellular or multicellular.All cells are produced from existing (other) cells i.e pre-existing cells produce new ones through a process called cell division.Binary fission is an asexual reproduction wherein the body of a prokaryotic organism such as bacterium, is divided into two (2) new identical bodies.
In order to demonstrate that all cells come from pre-existing cells, you should observe a bacterium performing binary fission (dividing) to form clones of itself.
In conclusion, the chromosome (pre-existing cell) of a bacterium containing deoxyribonucleic acid (DNA) and associated proteins replicates and then divides in half to form clones of itself (identical daughter cells).

Alana summarized what happens when a ball sitting on top of a grassy hill rolls down the hill.
The motionless ball has potential energy. Once the ball starts to roll down the hill, new kinetic energy is made. As the ball rolls across the grass, it slows down. The kinetic energy of the ball is converted to other forms of energy.
Which best describes Alana’s error?
The motionless ball does not have energy because it is still.
Kinetic energy is not made; it is a result of energy transformation.
The ball cannot slow down unless someone touches it.
The energy is not converted; it disappears.
Answer:
It's actually B that guy is wrong on Edge.
Explanation:
Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.
What are the various types of energy?The law of conservation of energy says that energy is neither created nor destroyed but only converted from one form to another, such as from the kinetic to the potential and vice versa. Here, the ball is placed at the top, where it has no motion, but the ball has potential energy, and that potential energy gets converted into kinetic energy when the ball starts to roll down the hill. After sometime, the ball spontaneously stopped on the ground, and the kinetic energy was converted into potential energy.
Hence, Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

The flask with phenolphthalein and NaOH changes color when the ___ gas formed during respiration was passed through the solution. The gas dissolves in the solution and forms____. Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a) oxygen..........water b) carbon dioxide.......water c) carbon dioxide........carbonic acid d) nitrogen........ammonia
Answer:
c
Explanation:
The flask with phenolphthalein and NaOH changes color when the carbon dioxide gas formed during respiration was passed through the solution. The gas dissolves in the solution and forms carbonic.
The dissolution of CO2 into an aqueous solution of NaOH is a two steps reaction.
1. CO2 first reacts with water to form carbonic acid
[tex]CO_2(aq)+H_2O(l) --> H_2CO_3(aq)[/tex]
This makes the phenolphthalein to change color.
2. The product in step 1 reacts with NaOH to form NaHCO3 and water
[tex]H_2CO_3(aq)+NaOH(aq)-->NaHCO_3(aq)+H_2O(l)[/tex]
Hence, the correct option is c.

Answer: replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
Explanation:
E. coli Is a species of bacteria that causes many different Infections in humans. Certain E. coli strains have developed resistance to antibiotics,
making Infections with these strains difficult to treat. How do bacteria such as E. coll, which reproduce asexually, galn new tralts such as
antibiotic resistance?
O A. by adapting to changes in environmental conditions without undergoing changes in their DNA
OB. by mutating their DNA in response to environmental conditions to gain beneficial traits
OC. by undergoing spontaneous mutations when they replicate, which increases genetic variation in a population
OD. by producing offspring with new gene assortments from genetic recombination, which increases diversity in a population
Answer:
The correct answer would be B
Explanation:
Antibiotic resistance in bacteria develops in response to the environment in which the bacteria survives.
The antimicrobial resistance trait is acquired by any species of bacteria through one of the two ways that are either by making changes in their DNA sequences or through horizontal gene transfer mechanisms.
In the given E. coli gained the trait to develop resistance against antibiotic by making changes in their DNA as once the gene is altered or mutated, the trait can be passed on to the offsprings.
Therefore, Option-B is the correct answer.
Answer:
B. By mutating their DNA in response to environmental conditions to gain beneficial traits
Explanation:
Through the process of natural selection, bacteria such as E coli can gain new traits that benefit them.
This can occur when a DNA mutation occurs, where the mutated gene is actually beneficial to respond to environmental conditions.
Then, these bacteria with the gene will survive and produce more offspring with the same gene. This is how E coli can develop antibiotic resistance.
So, B is the correct answer.
Atoms can bond together to form ionic compounds and molecule.

How does a stem cell become specialized into a heart cell?
Answer:
Explanation:
stem cells are manipulated to specialize into specific types of cells, such as heart muscle cells, blood cells or nerve cells. The specialized cells can then be implanted into a person. For example, if the person has heart disease, the cells could be injected into the heart muscle.
Daughter cells are created when stem cells divide properly in the body or a lab to create more cells. These daughter cells either develop into fresh stem cells or into differentiated cells with a more specific role, such as bone, blood, brain, or heart muscle cells.
How are stem cells differentiated?According to research, cardiomyocytes made from pluripotent stem cells can develop into beating human heart muscle cells that both produce the required signals and restore muscle lost during a heart attack.
Stem cells have the ability to multiply and develop into a variety of relatively mature cells. When inserted into a blastocyst, embryonic stem cells have the ability to develop into any organ in the human body.
Therefore, theoretically, every organ in the body might be replaced using embryonic stem cells.

Think and discuss:Suppose you are a farmer trying to grow plants in a greenhouse. Why would it be important to know what the limiting factor is
Answer:
Because limiting factors affect plant growth
Explanation:
A limiting factor is a condition that limits the population's growth in an ecosystem by slowing or stopping its growth. These factors are generated by the lack or excess of a particular resource. In plants, limiting factors include, among others, light, water, temperature, oxygen, food, (i.e., nutrients and minerals), space, etc. In this case, the farmer must know which greenhouse conditions are limiting factors in order to ensure the survival and optimal development of the plant population.
