What will be the effect on protein function if each polypeptide adopted only a single, inflexible shape based on its primary structure?
A) The protein ability to catalyze would be impaired. The tertiary structure could not appear, so those proteins could not perform their function.
B) The ability to regulate protein activity would be impaired. The peptide bonds would not be so stable compared to linkages in other types of macromolecules, so those proteins could not perform their function.
C) The ability to regulate protein activity would be impaired. The proteins would be either permanently active or inactive, depending on how they are folded.
D) The proteins would perform their functions normally.
The ability to regulate protein activity would be impaired. The proteins would be either permanently active or inactive, depending on how they are folded (Option C).
Proteins are complex biomolecules composed of linear chains of amino acids that interact to produce a final three-dimensional (3D) protein structure.Protein folding refers to the cellular mechanism by which proteins are folded to render a biologically active protein.Different heat shock proteins (Hsp) are involved in protein folding.If a protein or its subunits are not correctly folded, then it remains inactive because there is no interaction with its corresponding molecular partners (e.g., another protein in protein-protein interactions or DNA in the case of a transcription factor).Learn more in:

When would a point mutation occur?
O It can occur before and after cell division
O Before the cell divides
O After the cell divides
Before DNA replication
Answer:
Point mutations usually take place during DNA replication. DNA replication occurs when one double-stranded DNA molecule creates two single strands of DNA, each of which is a template for the creation of the complementary strand. A single point mutation can change the whole DNA sequence.

A 23-year-old man with an intellectual disability entered an institution because of polydipsia. He had habitually and repeatedly drunk considerable volumes and experienced diarrhoea and vomiting. This behaviour was uncontrollable; therefore, his family decided to admit him. The night of the day following his admission, he suddenly fell and was found unconscious. The patient died despite immediate transport to the emergency room by ambulance.
Autopsy findings:
The patient's height and weight were 166 cm and 49.4 kg, respectively. The external examination revealed no significant findings except a contusion on the facial region that resulted from his fall. The brain weighed 1383 g, with congestion. The heart weighed 328 g, and sclerosis and stenosis of the coronary arteries were not detected. The lungs weighed 422 g (left) and 509 g (right) with a high degree of swelling; the trachea and bronchi were empty. The greater curvature of the stomach was ruptured because of cardiac massage, and 3100 cc of fluid with food debris was observed in the intraperitoneal space. The bladder was empty, likely because of urethral catheterization, alepath Histological analyses revealed edema of the subarachnoid space. Protrusion and surrounding vacuolization were observed at the cardiac vessels. A portion of the cardiac muscle bundles was expanded. The lungs showed fluid in the bronchi, expansion of the capillary vessels, and deposition of fibrin around the vessels. The kidney showed edema of the tubular epithelium.

Multiponent cells are most likely to form after the first few divisions, if u dont belive me check your lesson.
trust my answers if YOU want to.
The most likely type of cells that form during the first few divisions is referred to as the multipotent cells.
Multipotent cells have the ability to replicate and differentiate into more
than one type of cells.The differentiation brings about specialization of the
cells which involves a group of cells which are formed having similar
structures and being able to perform similar functions.
This ensures that the human cells have their unique structure and functions
thereby enabling them work together to achieve a common goal.

A mint plant grows many horizontal branches along the ground from which new plants can arise. How can this be harmful to the growing plants?
Answer:
The aromatic aroma of mint isn’t as pleasing to many crop pests, so planting crops next to mint can deter these plant nemeses.
Explanation:
Mint can suffer from several plant diseases such as verticillium wilt, mint rust, mint anthracnose. If these strike, the best thing to do is get rid of your mint plants and get new, healthy ones. Just don't place them in the same spot or potting soil because that increases the chances that the disease will spread to the replacement plants as well. In Other Words, If you're feeling kind, you can call mint plants aggressive. If you don't like thugs taking over your garden, you will consider mint invasive. Because it grows by underground root runners, mint spreads easily and quickly. To contain it, grow mint in a 12- to 16-inch-wide pot so it can't ramble through your landscape.

If a fruit fly develops legs on its head instead of antenna, what is the most likely reason?
O Chromosomal non-disjunction resulting in extra sets of genes
O Conjugation errors during reproduction
O Frameshift mutation during transcription of mRNA
O Mutation affecting gene expression
Mutation affecting gene expression is the most likely reason for a fruit fly to develop legs on its head instead of antenna.
WHAT IS MUTATION:
Mutation is the process whereby an alteration or change occurs to the sequence of DNA either by mistake during replication or caused by mutagens.WHAT IS GENE EXPRESSION?
Gene expression is the process by which the information encoded by genes are used to synthesize products such as proteins etc. In the organism described in this question, the fruit fly develops legs on its head instead of antenna, it's most likely because the genes encoding the information for the synthesis of antennas on its head have been CHANGED OR MUTATED, hence, causing something else to be formed there.Therefore, mutations affecting gene expression can cause legs to be formed on the head of fruit fly instead of antenna.

Your lab team mixes dry baker’s yeast with warm water and divides the mixture between two test tubes. You add 5 grams of sugar to one test tube but nothing to the other tube. A small balloon is placed over the mouth of each test tube. After 30 minutes your team records the following observations.
Yeast and warm water: The water is cloudy after a minute. After 30 minutes the yeast is settled to bottom of tube, water is less cloudy.
Yeast, warm water and sugar: The water is cloudy, a few bubbles have formed on top of the water. After 30 minutes the water is cloudy, lots of bubbles in the test tube, balloon has inflated some.
What is the BEST inference you could make about the yeast based on the data?
(4 Points)
The yeast needs warm water to grow.
The yeast bubbles when it contacts sugar.
Yeast is a living organism that uses sugar for energy.
Yeast is not a living organism because it did not change when added to water.
Answer:
The yeasts are the eukaryotic, microscopic, unicellular organisms belonging to the kingdom fungi. Yeasts are widely used to prepare beer and wine. Yeasts break down the glucose and release ethanol and carbon dioxide. The best interference is yeasts bubbles when it contacts with sugar.
Explanation:
Yeasts are organisms, which can respire aerobically or anaerobically. During the experiment, when yeasts are placed in a test tube with sugar, it starts to grow. The warm water in the test tube ensures the rapid growth of yeast. Sugar is the source of energy that is required by the yeasts to grow. Thus, during the multiplication of the yeast, they utilize oxygen and food to yield carbon dioxide. The gas is evolved and can be tested by the inflated balloon placed over the test tube. The yeasts bubbles out when it comes in contact with the sugar. Thus, to perform any experiment on living organisms, the population of those organisms should be in large quantity. this can be achieved by providing the sources of energy.
Explain the relationship between urea cycle and citric acid cycle?
Answer:
one of its nitrogens through transamination of oxalacetate to form asparate and returns fumarate to that cycle.
Explanation:
The urea cycle is linked to the citric acid cycle by fumarate and by aspartate, which can be con- verted to malate by transamination (see Figure 23.22). ... Aspartate and arginosuccinate are the amino acids that link the two pathways. Aspartate is made by transamination of OxaloacetatA.

View Available Hint(s)
O They exit the ecosystem in the form of heat.
O They recycle within the ecosystem, being constantly reused.
O They flow through the system, losing some heat in the process.
o They depend on sunlight as their source.
O They cannot be obtained from decomposition.
They are recycle within the ecosystem being constantly reused ( B ) is the true statement
The energy from the sun is use in the formation of nutrients in plants that is consumed by the primary consumers ( Herbivores ) in the ecosystem, while the primary consumers will be consumed by the secondary consumers ( carnivores ). these waste product from the secondary consumers is decomposed by the tertiary consumers ( Fungi and bacteria ) to be reused by the Plants again.
Hence we can conclude that the true statement about the chemical elements in the eco system is that they recycle within the ecosystem being constantly reused.
