In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms.
a. True
b. False
Answers
Answer:
Explanation:
True.
In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms is a true statement.
What are Bacterial communities?Bacterial communities differ in their species makeup, the niches they occupy, and the effects they have on various ecosystems.
Communities defy a single, fundamental definition due to their complexity. Instead, they offer fascinating illustrations of dynamic processes that vary with ecological size. In the beginning of microbiology, there were difficulties in describing and classifying communities.
Robert Koch revolutionized the study of microbiology in the late 1800s by inventing his techniques for proving the link between an infection and an organism (Koch, 1876). Koch's hypotheses continue to be the "gold standard" for linking germs to illness or any other interesting event.
Therefore, In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms is a true statement.

What is the difference between traditional PCR and qPCR?
a. Traditional PCR has only 1 cycle whereas qPCR has multiple cycles
b. In traditional PCR, the presence or absences of a DNA sequence is analyzed upon reaction completion whereas qPCR monitors DNA amplification as the reaction progresses
c. Traditional PCR is an outdated technique which is unreliable and has not been utilized for years whereas qPCR is a newer and better technique which is always preferred nowadays.
d. Traditional PCR is monitored by an increases in fluorescence signal whereas it is impossible to monitor qPCR by increases in fluorescence signal
Answers
Answer:
The difference between traditional PCR and qPCR (Real-time PCR) is:
b. In traditional PCR, the presence or absences of a DNA sequence is analyzed upon reaction completion whereas qPCR monitors DNA amplification as the reaction progresses
Explanation:
Real-time PCR (qPCR) is an advanced tool for analyzing RNA and DNA. With Traditional PCR detection occurs at the end-point of the reaction, while with Real-time PCR, detection of the RNA and DNA sequencing is detected as the reaction is occurring. The advantages of the qPCR over the traditional PCR include higher precision and resolution, and increased dynamic range and sensitivity.

Down syndrome in humans is due to ________ of the 21 st chromosome.
Answers
Answer:
Down syndrome in humans is due to ADDITIONAL, PARTIAL OR FULL COPY of the 21 st chromosome.
Explanation:
Down syndrome is a genetic disorder in which an individual has a total of 47 chromosomes instead of 46 that is, 23 pairs of chromosomes which is found in normal individuals. This occurs as a result of the presence of additional, partial or full copy of chromosome 21. There are generic variations that occurs in chromosome 21 leading to down syndrome, these include:
-->Trisomy 21 : the individual has three copies of chromosome 21 instead of two copies due to abnormal cell division that occurred during development of sperm or egg.
--> Mosaic Down syndrome: the individual has some cells with an extra copy of chromosome 21 and it's caused by abnormal cell division after fertilization.
--> Translocation down syndrome: This type of down syndrome occurs when chromosome 21 gets attached to another chromosome which occurs during or after conception.
Generally the symptoms due to the presence of this extra genetic material includes:
--> short heights
--> poor muscle development
--> short neck
--> short fingers with small hands and feet
--> increased risk to development of dementia
--> greater tendency to develop obesity
Сотраге and contrast Simple Dominance to Incomplete Dominance."
Answers
Answer:
Simple dominance is when the dominant gene in a heterozygous organism expresses the dominant phenotype. Incomplete dominance is when a heterozygous organism exhibits a blending of both genes, recessive and dominant. Red and white flowers will "blend" and make pink flowers.
Incomplete dominance, only one allele in the genotype is seen in the phenotype. In simple dominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

Two students compare and contrast the composition of a plant and animals cells. Several observations are made during the investigation. Which observation is incorrect?
Plant and animal cell contain cell membranes.
Plant cell are contained within cell walls, while animal cells are not.
Plant and animal cells contain a nucleus.
Plant cell do not have cytoplasm.
Answers
Answer:
I believe the correct answer would be D- Plant cell do not have cytoplasm
Explanation:
Plant and animal cells both have a cytoplasm so D is the incorrect statement.
Two students compare and contrast the composition of a plant and animals cells. Plant cell do not have cytoplasm this observation is incorrect. Therefore, option D is correct.
What is cytoplasm ?The liquid present inside a cell but not in the nucleus of the cell. In a cell, the cytoplasm is where the majority of chemical processes occur.
The gel-like substance that fills a cell is called cytoplasm. It serves as a catalyst for chemical reactions. It offers a foundation for other organelles to function within the cell. A cell's cytoplasm is where all the processes for cell division, growth, and replication take place.
Rudolf von Kölliker coined the phrase in 1863, first using it as a synonym for protoplasm, but over time it has come to refer to the cell's interior and extracellular organelles.
The first phase of cellular respiration, known as glycolysis, as well as mitosis and meiosis are just a few of the numerous cellular processes that take place in the cytoplasm.
Thus, option D is correct.

Which type of macromolecules helps a cell brake down food? Lipids proteins carbonhydrates or nucliec acids
Answers
Answer:
Proteins
Explanation:
There are four major biomolecules found in living system namely; proteins, carbohydrates, lipids and nucleic acids. These biomolecules serve different and unique functions in the body. PROTEIN is a biomolecule that helps in the break down of food substances in the body as stated in this question.
Specifically, these function of breaking down food substances is carried out by ENZYMES, which are biological catalysts that are proteinous in nature i.e. structurally made of proteins. For example, amylase enzyme breaks down starch, lipases break down lipids. Hence, since enzymes that perform this disintegration function are PROTEINOUS, then PROTEINS are the biomolecules that perform the role.

When both lactose and glucose are available to E. coli, which part of the lac operon regulation assures that glucose will be metabolized first? When both lactose and glucose are available to E. coli, which part of the lac operon regulation assures that glucose will be metabolized first? Permease allows lactose to enter the cell when lactose enters the cell. The repressor binds to the operator in the absence of lactose. The repressor cannot bind to the operator in the presence of lactose. RNA polymerase transcribes the lac operon to make a single RNA molecule. CAP binds to cAMP and then to the promoter only in the presence of low glucose.
