Answer:
B.) A base pair deletion, resulting in a different amino acid
Explanation:
A base-pair deletion mutation is likely to have the MOST NEGATIVE effect on the protein it specifies (Option B).
A mutation is any alteration in the nucleotide sequence (DNA) of an organism.A base-pair deletion will change the Open reading frame (ORF) of the protein that is synthesized from a given gene sequence, thereby changing all aminoacids downstream the mutation.In consequence, a base-pair deletion can significantly alter the protein that will be synthesized from a given gene.Moreover, a substitution for a one-stop signal for another stop codon is neutral because it doesn't affect the resulting protein.In conclusion, a base-pair deletion mutation is likely to have the MOST NEGATIVE effect on the protein it specifies (Option B).

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.

Explanation:
If there are probability of 50% of producing male gamete then what would be the probability of producing transgender. When father is gay.
A) 10%
B) 20%
C) 30%
D) none
Answer: none.
Explanation: it doesn't matter whether father is gay or straight the gamete production do not effect
The probability of producing a transgender = None ( D ) when the father is gay
The probability of producing male gamete is not affected by the sexual orientation of the Father because the production of the male gamete is carried by the spermatogonia found in the testes of a male. and every male specie regardless of your sexual orientation have testicles where the spermatogonia undergoes mitotic divisions to produce the male gametes.
Hence the probability of producing a transgender given that the father is gay is non-existent i.e.0%

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.
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:

III only
I and II
I and III
I, II, and III
the answer is I and III
The correct process that represents ways nitrogen can enter the soil is III only which is rainfall.
Atmospheric nitrogen can not be used by most organisms due to fact that the three covalent bonds present in atmospheric nitrogen are very hard to break.
Nitrogen fixation takes place either:
By the microbes and produce ammonia by biological nitrogen fixation. or, Rainstorms, natural lighting, rainfall contribute to atmospheric nitrogen into nitrates through raindrops that reach the soil.Nitrates are the most bio-available form of nitrogen.Thus, the correct answer is - III only which is rainfall.

Please Hurry). The Science of Biology: Question 1: Explain how sunlight is the primary source of energy for your own life? Question 2: In terms of energy, what is the difference between glucose and ATP? Question 3: Explain the role of a hypothesis in a scientific investigation? ( Will Mark Brainliest if correct).
Answer:
1) The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs 2)Cellular respiration breaks down glucose into water and carbon dioxide producing 38 net ATP molecules. ATP is the energy containing nucleotide in cells while the energy found in glucose is used to make ATP. The key difference between glucose and ATP is the composition of these two molecules 3)The basic idea of a hypothesis is that there is no pre-determined outcome. ... A key function in this step in the scientific method is deriving predictions from the hypotheses about the results of future experiments, and then performing those experiments to see whether they support the predictions
Answer:
Explanation:
1) Well sunlight is very important to each of us because not only it gives us warmth, it also gives us vitamin D, which is very essential for our body.
2) Glucose is the energy that every living being absorbs and stores in their body. ATP is the energy that is ready to be used from every living being.
3) The hypothesis is a very important role in a scientific investigation, because it helps us suppose the experiment that we are about to realize and it's a possible answer to our scientific question.
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.
