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 .

Which of the following changes takes place during the second trimester of a
woman's pregnancy?
A. The fetus begins to form teeth.
0 0
B. The fetus begins rhythmic breathing movements.
C. The fetus's hands and feet appear.
D. The fetus develops toenails, lips, and eyelashes.
In FEOTAL DEVELOPMENT, there are various changes which occurs Both in the foetus and the mother. These changes are broadly grouped into three stages which includes:
--> First trimester: This stage starts from conception to 12 weeks. This stage in pregnancy involves the following changes in the foetus which is called an embryo at this stage:
• the major organ systems which includes the digestive system, the heart and circulatory system begins to develop
• facial features starts to develop.
• fetus begins rhythmic breathing movements at 10th week of this stage and continues through out the gestation period.
• teeth starts to harden and connect to the jaw bone at the 10th week of this stage.
• By the end of this stage baby's arms, hands, fingers, feet and toes are fully formed.
--> SECOND TRIMESTER: This stage starts from 13th week through 28th weeks of pregnancy. It involves the following changes:
• the heartbeat is now audible and this can be detected using the instrument called doppler.
• Your baby is covered by fine, feathery hair called lanugo and a waxy protective coating called vernix. Eyebrows, eyelashes, fingernails, and toenails have formed.
• the finger and toes are well defined with the prints visible enough.
--> Third trimester: This lasts from 29th week to due date which is usually at 40th week. The following changes occurs
• the brain continues to develop rapidly so that it can blink, close the eyes, turn the head, grasp firmly, and respond to sounds, light, and touch.
• it continues to develop reserves of body fat which will help out in early days after birth.
Therefore the CORRECT option is D which states that the fetus develops toenails,lips and eyelashes.

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.

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%

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.

Part D - The effect of gramicidin on oxidative phosphorylation When the protein gramicidin is integrated into a membrane, an H channel forms and the membrane becomes very permeable to protons (H ions). If gramicidin is added to an actively respiring muscle cell, how would it affect the rates of electron transport, proton pumping, and ATP synthesis in oxidative phosphorylation
Answer:
The correct answer would be -
Remains the same: proton pumping rate, electron transport rate, rate of oxygen uptake.
Decreases or goes to zero: rate of ATP synthesis, size of protein gradient
Explanation:
An H+ channel forms and the membrane becomes very permeable to protons if the protein gramicidin is integrated into a membrane. If gramicidin is added to an actively respiring muscle cell, it will affect the in the following manner:
Remains the same:
proton pumping rate, electron transport rate, rate of oxygen uptake.
Decreases:
rate of ATP synthesis, size of protein gradient
None of these will show an increase due to the addition of gramicidin tlo actively respiring muscle cells.

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.
