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.What is NOT true about cellular respiration?

Answer:
300
Explanation:
on edge2021
If zebra get 10% energy of 30,000 kJ which is 3,000 kJ of energy. Then Cheetah gain the energy of 300 kcal via energy transfer.
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.

All of the following are examples of the evidence that supports the endosymbiotic theory EXCEPT A. Mitochondria and chloroplasts divide in a process resembling binary fission. B. Mitochondria and chloroplasts are similar in size to bacteria. C. Mitochondria and chloroplasts have linear chromosomes. D. Mitochondria and chloroplasts have their own genomes.
Answer:
All of the following are examples of the evidence that supports the endosymbiotic theory EXCEPT for option C. Mitochondria and chloroplasts have linear chromosomes.
Explanation:
The endosymbiotic theory essentially states that some organules of the eukaryotic cells, such as mitochondria and chloroplasts, were once free-living bacteria. Probably, these organisms must have been phagocytosed, but not digested by another cell. On the contrary, these bacteria were able to adapt to their host so that the two cells established a dependent relationship with each other.
Due to its similarities to other free-living bacteria, it is speculated that chloroplasts must derive from cyanobacteria and that mitochondria must derive from rickettsias.
This theory is supported by a few characteristics of the chloroplasts and mitochondria that suggest they were once a free cell. For example,
Both organelles present their own genetic material. This DNI is bi-catenary and circular, identical to the bacterial DNA, and very different from the eukaryotic cell´s DNA. These organelles divide by binary fission (not by mitosis) and can synthesize their own ribosomes and organelles. Both organelles present a double membrane, a characteristic that reinforces the idea of being phagocyted. The internal membrane looks identical to the bacterial membrane, while the external membrane looks like the eukaryotic one. The sizes of the organelles are similar to the size of some procaryotes.
The membrane that surrounds a Golgi apparatus is very similar in structure to other membranes in the cell. Damage to the Golgi apparatus would disrupt which of the following processes ? The breakdown of glucose to generate ATP The degradation of waste products The modification and sorting of proteins destined for secretion The translation of mRNA into proteins
The modification and sorting of proteins destined for secretion
Since this is the role of the golgi aparatus(synthesis of glycolipids for example)
The first statement is the role of the mitochondria
the second statement is the role of the lysosome
the fourth statement is the role of the ribosome

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.

Explanation:
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.

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.

how many kilometers will the pacific plate travel in 1 million years
Answer:
The Pacific plate travels approximately 107 km in a million year.
Explanation:
Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)
R = d/t
To calculate it in millimeters per year we need to convert it:
1 km = 1000 m
1 m = 100 cm
1km = 100,000 cm
We know by the theory that the Pacific plates might be moving approximately between 10.6 - 10.75 cm/year. So, we might say that it moves 10.7 cm/year. So,
The Pacific plate moves 10.7 cm in one year
1 year-------------------------------- 10.7 cm
1,000,000 years ----------------- X = 10700000 cm
100,000 cm -------------- 1 km
10700000 cm -----------X = 107 km.
The Pacific plate moves approximately 107 km/my.
