Salivary amylase is an enzyme in humans that breaks down starches. What substances would humans have difficulty digesting without this enzyme
Group of answer choices
Answer:
Carbohydrates
Explanation:
High in fats and very fatty
In the absence of salivary amylase, humans would have difficulty digesting carbohydrates.
What is salivary amylase?Salivary amylase is produced by the salivary glands located towards the back of our mouth. Salivary amylase is a very small percentage of the total amount of amylase produced by the body.
Most of the amylase in the body is secreted by the pancreas. Salivary amylase is secreted in the saliva. This begins the process of the breakdown of food in the mouth itself.
Salivary amylase breaks down carbohydrates into maltose units which is a disaccharide. The maltose is ultimately broken down into glucose.
Carbohydrates are a very significant portion of the diet of a large percentage of the global population. Various kinds of bread and rice have a large portion of them composed of carbohydrates.
Therefore, in an absence of salivary amylase, humans would have difficulty digesting carbohydrates.

what are the 7 factors of classification of living things
1 Nutrition
Living things take in materials from their surroundings that they
use for growth or to provide energy. Nutrition is the process by
which organisms obtain energy and raw materials from nutrients
such as proteins, carbohydrates and fats.
2 Respiration
Respiration is the release of energy from food substances in all
living cells. Living things break down food within their cells to
release energy for carrying out the following processes.
3 Movement
All living things move. It is very obvious that a leopard moves but
what about the thorn tree it sits in? Plants too move in various
different ways. The movement may be so slow that it is very
difficult to see.
4 Excretion
All living things excrete. As a result of the many chemical
reactions occurring in cells, they have to get rid of waste products
which might poison the cells. Excretion is defined as the removal of
toxic materials, the waste products of metabolism and substances
in excess from the body of an organism.
5 Growth
Growth is seen in all living things. It involves using food to
produce new cells. The permanent increase in cell number and size
is called growth.
6 Reproduction
All living organisms have the ability to produce offspring.
7 Sensitivity
All living things are able to sense and respond to stimuli around
them such as light, temperature, water, gravity and chemical
substances.

Put the following in order from most thermal energy to least thermal energy.
from hottest to coldest:
- the turkey
- the tea
- the beach
- the, what is it, an iceberg or ocean?
- the ice cube
refer to the other question I answered by you. 0 degrees Celsius would be frozen, 100 would be boiling hot. Since -2 is the lowest, that would be the coldest/ least amount of thermal energy. 60 degrees Celsius is the highest, so it has the most thermal energy. Again, thermal energy is just heat energy, so you just need to figure out which is hottest.

The condition of ketoacidosis is Select one: a. a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH. b. due to a lowered production of ketone bodies than is normal. c. the increase in pH of the cells due to ketone body production. d. only found when anaerobic catabolism of fat occurs.
Answer:
The correct answer is option A ( a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH.)
Explanation:
Ketoacidosis results in a type of body metabolic state where the urine concentrations are high in ketone bodies, such as acetoacetic acid , 3-hydroxybutyrate. Fatty acids are converted to ketone bodies, resulting in a very high level of ketone bodies which automatically lowers the blood pH.
Ketoacidosis is of different types, Diabetic ketoacidosis, alcoholic ketoacidosis, starvation ketoacidosis. They are all associated with the accumulation of ketone bodies within the bloodstream. The underlying disease common with ketoacidosis is Diabetes.
Messenger RNA (mRNA) travels from the nucleus of a eukaryotic cell to the ribosome. At the ribosome, the amino acids are lined up in order as the tRNA molecules line up with complementary bases on the mRNA. This process is called _____ and results in the formation of _____.
Answer:
The correct answer is - translation, polypeptide/amino acid chain.
Explanation:
The translation is the process that involves the movement of mRNA from the nucleus to the ribosome and where amino acids are formed in sequence linked with one another in the same order as the transfer RNA line up with the complementary bases encoded on the messenger RNA or mRNA.
This amino acid chain or the polypeptide folds in a specific way to active protein for the specific function or expression. This process is the last stage or phase of protein synthesis.

What is the classification of virus
Answer:
Viruses are classified into 4 groups based on their shape: filamentous, isometric , enveloped, and head and tail.
Many viruses attach to host cells to facilitate penetration of the cell membrane, allowing their replication inside the cell.
The virus core contains the small single- or double-stranded genome that encodes the proteins that the virus cannot get from a host cell.
Explanation:
not sure if this is what you are looking for
According to the Baltimore classification system, Viruses are classified into seven classes on the basis of their morphology and function.
What is Virus?A Virus may be defined as a type of microorganism that consists of a nucleic acid molecule in a protein coat and infects cells and may cause disease.
Viruses are classified into seven classes, each of which has its own families of viruses and has differing replication strategies.
Class 1: Double-stranded DNA viruses.
This type of virus usually must enter the host nucleus before it is able to replicate. An Example is Adenoviridae.
Class 2: Single-stranded DNA viruses.
Such types of viruses replicate within the nucleus and pertain highly in vertebrates. An example is Circoviridae.
Class 3: Double-stranded RNA viruses.
Such types of viruses do not depend on host polymerases for replication. An example is Birnaviridae.
Class 4: Single-stranded RNA viruses (positive sense).
Such types of viruses have polycistronic mRNA which is translated into a polyprotein. An example is Flaviviridae.
Class 5: Single-stranded RNA viruses (negative sense).
Such types of viruses must be transcribed by viral polymerases into complementary forms. An example is Filoviridae.
Class 6: Single-stranded RNA viruses (positive sense) that replicate through DNA intermediate.
Such types of viruses use the enzyme reverse transcriptase to convert the positive sense RNA into DNA. An example is Retroviruses.
Class 7: Double-stranded DNA viruses that replicate through a single-stranded RNA intermediate.
Such types of viruses have a double-stranded gapped genome that is subsequently filled into a covalently closed circle that serves as the template for the production of viral mRNA. An example is the Hepatitis B virus.
Therefore, it is well described above.

Senescence __________. Question 5 options: a) begins at the moment of conception and accelerates after age 40 b) occurs across all parts of the body at the same time and speed c) begins once body structures reach maximum capacity and efficiency d) occurs because the physical body wears out from use
Answer: c. Senescence begins once body structures reach maximum capacity and efficiency
Explanation: Senescence is simply ‘growing old’. Aging sets in at the time when physical development is complete - when a person reaches their ‘prime’. After that a person is ‘past their prime’ which is the subjective recognition of the on set of gradual deterioration. The biological rationale is that the purpose of life is to survive to reproductive age and to reproduce, and in some species to assist progeny to survive to reproductive age. Beyond that, survival has limited value.
An analogy is the length of an elephant’s trunk. It is as long as it needs to be, determined by natural selection, but no longer than it needs to be for optimum efficiency, again determined by natural selection.
