What does yeast produce during aerobic cellular respiration?
Answer:
Carbomdioxide and water
Explanation:
Yeast is a unicellular fungus that is capable of both aerobic and anaerobic cellular respiration depending on the availability of oxygen. Yeast undergoes aerobic respiration in the presence of oxygen but undergoes fermentation (anaerobic) in the absence of oxygen.
However, like every other organism, yeast undergoes aerobic cellular respiration to yield CARBON DIOXIDE (CO2) AND WATER (H2O) as products.

True or false: High levels of adrenaline decrease the ability to remember trauma but
increase the ability to concentrate. *
O True
O False
Answer: False
Explanation:
This is a false statement because researches have shown that Adrenaline is helping and it is good for long-term memory and if we have lots of Adrenaline that is making our brain work and remember better and more.
If we are recalling being insulted, falling, or something more, we can still retrieve those memories because of the Adrenaline and that means that it is not decreasing the ability to remember the trauma.

Why some bacteria produce Nanoparticles when grown on trace elements?
Answer:
· As particles get smaller, their magnetic properties, particularly with regard to temperature, also diminish. However, several strains of bacteria produce magnetite – fine, uniform nanoparticles that have desirable magnetic properties. These magneto tactic bacteria use a protein to form crystalline particles about 50 nanometers in size.
Fine particles have a diameter range of 100 to 2500 nanometers, while ultrafine particles have a diameter range of 1 to 100 nanometers.
What are Nanoparticles?Size-related characteristics present in tiny particles may or may not be present in nanoparticles. Even though individual molecules are ultrafine particles, they are not typically referred to as nanoparticles.
Nanoclusters have a restricted size distribution with at least one dimension between 1 and 10 nanometers.
On the other side, nano powders are aggregations of nanoparticles, nanoclusters, or ultrafine particles. Nanocrystals are crystals with a size smaller than a nanoparticle.
Therefore, Fine particles have a diameter range of 100 to 2500 nanometers, while ultrafine particles have a diameter range of 1 to 100 nanometers.

what are the plant organ systems
Answer:
roots
leaves
the stem
reproductive organs, such as male and female sex organs in flowers
Explanation:
Describe several adaptations that enable plants to reduce water loss from their leaves. Include both structural and physiological adaptations.
Answer:
1. Structural adaptations:
- leaves coated in a waxy cuticle
- a fewer number of stomata on the cell surface
2. Physiological adaptations:
- stomatal closure
- osmotic adjustment
Explanation:
In plants, leaves may be covered by a waxy layer to avoid the loss of water vapor (transpiration) through the epidermis. Stomata are small pores localized in the epidermis of leaves and upper organs that control gas exchange, including water vapor. Plants can retain water by having fewer stomata in their leaves, or well by closing stomata during the hot day time and in hydric stress conditions. Finally, osmotic adjustment is an adaptive mechanism caused by the active accumulation of solute in the vacuoles of plant cells (including leaf cells), which is also used by plants to avoid the harmful effects of hydric stress.
The adaptations that enable plants to reduce water loss from their leaves include:
Waxy coatings on their leaves.Some plants have succulent stems.Some plants shed their leaves during summer.Reduced number of stomata.It should be noted that the waxy leaf cuticle is impermeable to water and this stops evaporation. The reduced number of stomata also reduces the transportation rate.
Another adaptation is the leaves that are reduced to spines. This reduces the surface area for transpiration.

The adipose tissue metabolism of patients suffering from Von Gierke disease resembles the adipose tissue metabolism of a __________ individual.
A) Healthy
B) Starved
Answer:
The correct option is B
Explanation:
Von Gierke disease is an inborn error of metabolism (hereditary disorder) in which the body cannot convert glycogen (storage form of glucose in liver and muscle) back to glucose. This disorder is caused by the deficiency of the enzymes glucose-6-phosphatase or glucose-6-phosphate translocase. This generally causes blood sugar to be low (since liver releases this excess sugar to the body in the form of glycogenolysis when the body needs it).
Since the body cannot derive energy from the glucose present in the liver and muscle, the adipose tissue which is a storage site for energy in the form of fat is usually depleted as it becomes the alternative path for energy production (for some organs) just as in a starved individual who has had his/her glycogen storage depleted.

can be identified:
Both consist of linked monomers via the process of dehydration reactions
Both consist of linked monomers via the process of hydrolysis.
Both consist of linked sugars via the process of dehydration synthesis.
O O
Both consist of linked amino acids via the process of hydrolysis.
Answer:
The comparison of proteins and polysaccharides establishes that they have similarity in both consist of linked monomers via the process dehydration reactions.
Explanation:
Both proteins and polysaccharides are polymers whose structure consists of the union of monomers. In the case of proteins the monomer is the amino acid, while in the polysaccharides can be glucose molecules.
The process of polymer formation is called polymerization, and one of the reactions that this process allows is polycondensation, where a water molecule is lost in the union of monomers.
The loss of water in a chemical reaction involves dehydration, a characteristic shared by the processes of adding monomers to proteins and polysaccharides.
The other options are not correct, because
Hydrolysis produces the rupture of molecules, with the intervention of water.Only polysaccharides are sugars bound by the dehydration synthesis process.Only proteins consist of amino acids linked through the process of hydrolysis.PLEASE HELP HIGH SCHOOL BIOLOGY

Which of the following is NOT an accurate description of protein synthesis and folding?
a. Many copies of a protein can be synthesized simultaneously from the same mRNA.
b. The 3D shape of a protein is determined largely by the ribosome forming the protein.
c. The entire chain of amino acid exits the ribosome before it begins folding into its 3D shape.
d. The first encoded amino acid in every protein is methionine.
Answer:
OPTION b. "The 3D shape of a protein is determined largely by the ribosome forming the protein" is NOT an accurate description of protein synthesis and folding.
Explanation:
a. Many copies of a protein can be synthesized simultaneously from the same mRNA. TRUE. As a ribosome moves along the mRNA chain synthesizing a new protein, another ribosome might follow it, synthesizing another protein from the same mRNA chain. And so on. So, at the same time, many ribosomes might be attached to the mRNA, synthesizing many copies of the protein, but at different development levels. The mRNA chain together with many ribosomes is called a polyribosome.
b. The 3D shape of a protein is determined largely by the ribosome forming the protein. FALSE. What determined the 3D structure of the protein is the amino acid sequence of that particular polypeptide. Each amino-acid has different properties (hydrophobic, hydrophilic, positively charged, negatively charged) and they interact with each other by different bonds that depend on those poperties. So the amino acids composing the proteins and their interaction, is what models the structure of the protein.
c. The entire chain of amino acid exits the ribosome before it begins folding into its 3D shape. TRUE. When the ribosome reaches the end codon, the elongation process has finished, and the new protein leaves the ribosome and is translocated to the RER lumen where it is going to get folded.
d. The first encoded amino acid in every protein is methionine. TRUE. Almost always, the first amino acid located by the tRNA is the methionine, codified by the initiation codon AUG. This amino acid is frequently eliminated at the end of the process.

Which of the following statements BEST defines vestigial structures? :
-Structures that are different in different organisms
-Structures that are still present but currently serve little to no purpose
-Structures that are the same in different organisms
-Structures that are different between the infant and adult forms of an organism
Answer:
Structures that are still present but currently serve little to no purpose
Explanation:
Vestigial structures/organs are general defined as structures/organs that are present but poorly developed without any functional use in the present living organisms but thought to have been fully developed and functional in their ancestors.
Fully developed and functional organs gradually become less developed and non-functional across generations as the environment keeps changing and organisms found lesser use for the organs. An example includes the caudal vertebrae found in man which is kind of useless but thought to have been fully developed and functional in the ancestors of man - the monkeys.
Vestigial organs are often used as one of the morphological evidence of the evolution of living organisms.

What are the levels of energy transfer in a food chain?
In an ecosystem, the Food chain is the cyclical event among producer, consumer, decomposer and energy in the form of food.
A feeding level through which energy in the form of food is transferred from one organism to other in an ecosystem called as trophic level.
Primary producers which are plants and algae, Primary consumers are the herbivores and Secondary consumers are both carnivores and omnivores, Tertiary consumers and quaternary consumers are carnivores.
Autotrophs can convert light energy to chemical energy via photosynthesis, then to primary consumers followed by secondary consumers and finally transferred to the tertiary consumers.
The energy transferred to each level remains 10% only.
Thus cheetah would acquire 300 kcal of energy.
