An E. coli cell contains about 15,000 ribosomes, which carry out protein synthesis. Assuming ribosomes are spherical and have a diameter of 20.0 nm, calculate the fraction of the E. coli cell volume that is occupied by ribosomes.
Answer:
14.57%
Explanation:
From the previous lesson, we understood that the Volume of E.coli = 4.13 × 10⁻¹⁹ m³
The diameter of the ribosome = 20 nm
Radius will be D/2 = 20 nm/2 = 10 nm
The volume of the sphere since the shape of the ribosome is spherical = 4πr³
∴
The volume for each ribosome = 4πr³
For 15000 ribosome, we have:
[tex]= 15000 \times (\dfrac{4}{3}\pi) ((10^{-8})^3)[/tex]
[tex]= 15000 \times (\dfrac{4}{3}\pi) (10^{-24})[/tex]
= 6.283 × 10⁻²⁰
Thus, the fraction of E.coli volume occupied by the ribosome can be determined by using the formula:
[tex]= \dfrac{Vol. \ of \ ribosome}{Vol. \ of \ E.coli}\times 100[/tex]
[tex]= \dfrac{6.283 \times 10^{-20}}{4.31 \times 10^{-19}}\times 100[/tex]
= 14.57%

Question 2 please help choices are prokaryote or eukaryote
Answer:
1. Circular chromosome, no mitosis = PROKARYOTES
2. Sterols in membrane, performs exocytosis = EUKARYOTES
3. Cell wall and mitochondria present = EUKARYOTES
4. Spirillum shape present = PROKARYOTES
Explanation:
Prokaryotes are organisms that notably lack a membrane bound nucleus while eukaryotes possess a membrane bound nucleus. Although, there exists other characteristics and features that distinguishes these two domains of organisms.
- Circular chromosome is a feature possessed by prokaryotic organisms e.g. bacteria. Also they do not undergo mitosis, instead they perform binary fission.
- Sterols are a class of lipids present in the membranes of all eukaryotes. Prokaryotes lack this feature. Also, eukaryotes perform the process of exocytosis, which is how eukaryotic cells release waste particles outside the cell.
- Mitochondria is a structure present only in eukaryotic organisms. Hence, an organism that possesses both cell wall and mitochondria is an EUKARYOTE.
- Spirillum is a characteristics of spiral shaped bacteria called spirochetes. Since bacteria are prokaryotic, hence, the spirillum shape is a prokaryote.
How photosynthesis happen with explanation
Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose
Explanation:
Explanation:
photosynthesis is a process in which green plant use energy from the sun light to transfer carbon dioxide ,water and mineral into oxygen and other organic compounds .
photosynthesis happen when water is absorbed by root of green plants and is carried by the xylem and carbon dioxide is obtained from air that enters leaves through the stomata and diffuses to the cell containing chlorophyll .The green plans pigment chlorophyll is uniquely capable of conserving the active energy of light into a latent from that can be stored (in food) and used when needed .

If one strand of DNA has the sequence 5'ATCG 3', what would be the sequence of the matching DNA strand
Answer:
Each strand is made up of a sequence of four nucleotides, A, C, G, and T. The order of the nucleotide sequence encodes genetic information. Since the nucleotides pair in a predictable way — A with T, and C with G — each strand of the DNA is always complementary to the other.
Answer:
3' TAGC 5'
Explanation:
A-T, C-G

b.lymphatic system and digestive system
c.nervous system and excretory system
d.skeletal system and muscular system
Answer:
The answer is D. skeletal system and muscular system.In the musculoskeletal system, the muscular and skeletal systems work together to support and move the body. The bones of the skeletal system serve to protect the body's organs, support the weight of the body, and give the body shape.
What is a common role of a coenzyme in a reaction as stated in class Group of answer choices To lower the activation energy of a reaction further The donation of atoms to a reaction To alter the enzymes shape To assist the substrate by binding to the enzyme, enabling substrate to active site engagement
Answer:
To assist the substrate by binding to the enzyme, enabling substrate to active site engagement
Explanation:
A coenzyme is a molecule that functions to aid the enzyme in catalyzing a reaction. The coenzyme does this by binding to the active site of the enzyme, then allowing substrate to bind to the enzyme for reaction to occur.
In other words, the coenzyme assists the substrate by binding to the enzyme, enabling substrate to active site engagement.
The zinc chloride produced by the reaction is in what state
Answer: Solution in Water
Explanation:
I believe this refers to the reaction between Zinc and Hydrochloric acid.
When this happens, the solution will be Zinc Chloride but as it happened in a solution (the acid), the resulting Zinc Chloride salt would be in aqueous form which means that it would be a solution in water which is the other product of this reaction.
Had the zinc reacted with gaseous HCI, it would have resulted in a Zinc Chloride with no liquid in it.

What is natural selection?
Answer:
Basically in simple terms, a process in which capable animals can adapt and live longer to their environment than to others. Like a light colored mice on dark rock wouldn't survive unlike dark colored mice
Explanation:
In nature, living organisms have to navigate conditions (such as severe heat, extreme cold, drought, predation, food scarcity, etc) surrounding their existence in order to survive.
The theory of evolution states that as they conquer these conditions, their behavior and physical abilities, and traits evolve and become efficient at doing so.
These traits are then passed on to their offspring via the process of reproduction.
The process by which their physical qualities change to survive their environment is called adaptation.
Those who are unable to evolve are terminated by the harsh conditions of nature. Those who are unable to pass their abilities to survive to their offspring also get wiped off. Those who adapt and reproduce are deemed to be selected naturally to survive hence the term - Natural Selection.
Hence natural selection is a component of evolution.
Evolutionists have stated that the Giraffe is an example of an animal that evolved. It developed a long neck to enable it to reach for food far off the ground and on trees when there was a condition that wiped off shrubs available for them to graze on easily off the ground.
As giraffes with longer necks grazed and fed well, they passed on the gene to their offspring whilst those without adequately long necks got terminated by nature.
Another example is given in the attached picture. The animal in the picture is a desert dragon lizard adapting the color of its skin to blend to its environment in order to escape being spotted by desert hawks that prey on them.
