The biological classification of organisms is called taxonomy. Based on your own investigation, discuss the importance of taxonomy in biological research.
Answer:
mark me as brainliest
Explanation:
It helps to ascertain the number of living beings on Earth. More than one million of species of plants and animals have been discovered and classified so far. It aims to classify the living organisms. Millions of organisms are classified scientifically in categories, which helps to have a better understanding
The theory and practice of characterizing, naming, and classifying living things is known as taxonomy. Such research is critical for a basic knowledge of biodiversity and its preservation.
What is the importance of taxonomy in biological research?Taxonomy is important because:
It aids in estimating the number of living beings on the planet. nearly one million plant and animal species have been identified and classified till date.Its goal is to classify living things. Thousands of creatures are scientifically divided into categories, which aids in understanding.It aids our understanding of the characteristics seen in plants and animals.It depicts the physical development in chronological order.It provides an overview of the local fauna and flora, which aids in the identification of endemic species.learn more about taxonomy here:

The sodium-potassium pump does not do which of the following actions?
-Moves sodium molecules against their concentration gradient into the cell
using ATP.
-Moves sodium molecules against their concentration gradient out of the cell
using ATP.
-Maintains the cell's physiological needs by establishing an electrochemical
gradient.
-Moves potassium molecules against their concentration gradient into the cell
using ATP.
The sodium-potassium pump does not allow the movement of sodium molecules against their concentration gradient into the cell with the use of ATP molecules.
In sodium-potassium pump, the sodium moves outside the cell whereas potassium moves inside the cell with the help of using ATP molecules. The sodium-potassium pump maintains the gradient of higher concentration of sodium extracellularly means outside the cell and a higher level of potassium intracellularly means inside the cell. This process is done only in the presence of ATP molecules that provides a force for the movement of sodium and potassium so we can conclude that no movement of sodium occur inside the cell in the sodium-potassium pump.
https://brainly.com/question/24347696
Answer: Moves sodium molecules against their concentration gradient INTO the cell using ATP.
Explanation:
The sodium-potassium pump moves sodium molecules against their concentration gradient out of the cell and moves potassium molecules against their concentration gradient into the cell. It also helps to regulate internal physiological needs through gradients. However, it doesn’t move sodium ions into the cell—that occurs through passive transport.

Five major reasons why gymnosperms are more advanced than pteridophytes are highlighted below:
WHAT ARE GYMNOSPERMS AND PTERIDOPHYTES?
Gymnosperms are a group of higher plants that produce naked seeds i.e. seeds not cased by a fruit. Pteridophytes are a group of lower plants that have vascular bundles.
WHY ARE GYMNOSPERMS ADVANCED THAN PTERIDOPHYTES?
Gymnosperms bear seeds while pteridophytes bear spores (seedless)Gymnosperms do not require water for fertilization to occur while pteridophytes require water for their fertilizationGymnosperms have a well developed root system while pteridophytes do not have a well developed root system (they use rhizoids)Gymnosperms exhibit secondary growth while pteridophytes do notGymnosperms undergo pollination while pteridophytes do not.Learn more at: https://brainly.com/question/10517712

Which of the following shows the correct energy flow during aerobic respiration?
A. Lipids, Glucose, ATP, cells
B. ATP, Glucose, cells
C. Carbohydrates, Glucose, ATP, cells
D. Carbohydrates, Glucose, Lactic acid, ATP
The correct energy flow during aerobic respiration is ATP, Glucose, and cells. Thus, the correct option is B.
What is Aerobic respiration?Aerobic respiration may be defined as the process of conversion of glucose into carbon dioxide, water, and energy via the intermediate product of pyruvate in presence of air.
The release of energy in aerobic respiration is found to be greater as compared to anaerobic respiration.
This released energy is immediately used to synthesize a molecule called ATP via glucose that fuels the cells for metabolic activities.
Therefore, the correct option for this question is B.

Explanation:
The precursor of EGP is translated from a transcript that has had one non templated nucleotide added to the open reading frame. This change does not create or eliminate a stop codon. Compared with the protein sGP, which is produced from the unedited transcript, EGP most likely has the same primary:
Answer:
Explanation:
It was added somewhere in the middle. Since this is a frameshift, everything downwind of the addition will most likely be different.
The question is basically asking, if you change everything from the middle to the end of an amino acid sequence, which end changes and which end would remain the same?
It basically asks, when amino acids are assembled into proteins, are they built from the amino to the acid direction, or the acid to the amino direction?
The answer is that amino acid sequences are always assembled N to C, much like nucleotide sequences are built 5 to 3.

Why is it necessary to check total aerobic microorganisms in microbiological quality control but not to test total anaerobic microorganisms?
Answer:
While many microbes are harmless to humans, others can cause serious problems. They can spoil food, introduce toxins, cause disease and lead to a host of other problems. The importance of microbiological testing is to quickly identify these contaminants and treat them before they do irreversible damage.
Explanation:
Aerobic bacteria are bacteria that can grow and live when oxygen is present.

A suspension of yeast cells is being grown under anaerobic conditions such that glucose is metabolized to ethanol and carbon dioxide. An inhibitor of alcohol dehydrogenase is added to the suspension, the cells rapidly die. Explain.
Answer:
The correct answer is - NAD needed to keep glycolysis going is not being recycled so the entire process is shut down and no ATP is produced
Explanation:
Alcohol dehydrogenase plays role in metabolizing the bulk of ethanol consumed as part of the diet and their activities contribute to the rate of ethanol elimination from the body.
Inhibitor of this zinc enzyme prevents it to perform its function which results in NADH generated during anaerobic conditions glycolysis cannot be recycled back to NAD+, So the ATP production pf anaerobic condition through glycolysis cannot be maintained.
