Daylight Savings Time has pros and cons. Do you think the pros outweigh the cons and therefore Daylight Savings Time should continue? Instead, do you think the cons outweigh the pros and therefore Daylight Savings Time should be abolished?
Explain.
Answer:
It should be abolished
Explanation:
It doesn't help anyone. The idea is that people will use less resources but because some people sleep throughout the day and work at night (especially now that we are at home). Its counter intuitive, it used to work but not everything that works for the past, works for the future.

Explanation:
What is the correct sequence of events that occur during protein synthesis?
1.mRNA is formed
2.amino acids form polypeptides.
3.a strand of dna segment unwinds.
4.mRNA attaches to ribosomes.
5.tRNA supplies the required amino acids.
Answer:
3, 1, 4, 5, 2
Explanation:
DNA helicase enzyme will unwind DNA into 2 segments for a template. Complementary nitrogenous bases will attach themselves to one of the DNA strands. mRNA carries codons for instructions from DNA. mRNA leaves the nucleus and joins with a ribosome (tRNA) in the cytoplasm. tRNA has anticodons which are complementary to a specific mRNA molecule. tRNA pairs with and translates instructions that the mRNA is carrying. Each amino acid delivered to the ribosome by tRNA begins forming a chain of amino acids, called a peptide bond.
4. What is the difference between a Nucleolus and a Nucleoid?
The nucleus is the largest and the most important cell organelle in a eukaryotic cell. A nucleus is a membrane-bound organelle that houses the genetic material of eukaryotes in DNA. The nucleus consists of protein fibres or the DNA inside chromatin fibres. Nucleoids contain the genetic material of prokaryotes in the cytoplasm. The nucleoids usually consist of a single chromosome.
Let us look at more difference between nucleus and nucleoid in the table given below.
Answer: It has different letters.
Explanation: Nucle = prefix.
Olus in Nucleous and Oid in Nucleoid

explain why SARS-COV-2 is classed as a pathogen
Answer:
SARS-CoV-2 is the seventh coronavirus strain known to infect humans and it causes respiratory disease in humans. These viruses infect humans and are currently causing a pandemic in the world.
A pathogen is an infectious organism that causes illness or disease to its host. There are many types of pathogens that infect the body of the host that disrupts the normal physiological process of an organism. SARS CoV2 is also a pathogen as it infects the human body and disrupts its physiology and causes disease.
Scientists looking for a repressor of the androgen receptor (AR)-mediated transcription gene discovered a protein, Ankrd1. ARs were observed to bind to Ankrd1 and, in cells where Ankrd1 was over-expressed, AR-mediated transcription was inhibited. The scientists also detected lower levels of ARs when Ankrd1 was overexpressed using chromatin immunoprecipitation (ChIP) and Ankrd1 was not detected by ChIP.Based on these observations, which of the following conclusions would the scientists most likely draw?
A. Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription
B. Ankrd1 is binding to the promoter and blocking ARS from binding, which prevents transcription of AR- mediated genes.
C. Ankrd1 is binding to multiple sites and causing DNA to loop, preventing ARS from binding and activating gene transcription
D. Ankrd 1 is binding to chromatin, recruiting proteins that remove acetyl groups, and silencing transcription of that region of DNA.
Answer:
D. Ankrd 1 is binding to chromatin, recruiting proteins that remove acetyl groups, and silencing transcription of that region of DNA.
Explanation:
Ankrd is a binding chromatin, there is recognition that mutation is deregulating the chromatins. The proteins remove acetyl groups and then the region for DNA transcript. The recruitment chromatin is associated with proteins are enzymes which are chemical moieties.
Answer:
Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription

Explanation:
Combining your knowledge of rates of diffusion with your knowledge of muscle physiology, explain why it is advantageous for oxidative muscle fibers (which depend on aerobic metabolism to generate ATP) to have smaller diameters compared to glycolytic muscle fibers.
Answer:
To provide quick energy to the muscles.
Explanation:
It is advantageous for oxidative muscle fibers to have smaller diameters compared to glycolytic muscle fibers because these fibers depend on aerobic respiration to provide energy to muscle contractions. This smaller diameter enables the oxidative muscle fiber to move very quickly in order to provide quick energy to the muscles. If their diameters are big so they are unable to provide quick energy in the form of ATP to the muscles for their contractions.
Cytokinesis in animal cells happens when the:
A: cell wall pinches in to separate the cytoplasm.
B: cell plate forms across the middle of the cell.
C: chromosomes line up in the middle of the cell.
D: cell membrane pinches in to separate the cytoplasm.
Answer: D
Explanation:
Cytokinesis is basically the formation of 2 new cells. C describes metaphase and A and B are talking about cytokinesis in a plant cell because animals don't have cell walls or plates. So the right answer has to be D

Please WHAT IS MEMBRANE POTENTIAL
Answer:
Membrane potential is a potential gradient that forces ions to passively move in one direction.
Explanation:
Membrane potential is a potential gradient that forces ions to passively move in one direction: positive ions are attracted by the 'negative' side of the membrane and negative ions by the 'positive' one.
In a population of birds, the average beak size is favored. What type of selection is this?
a. directional
b. disruptive
c. tabilizing
d. kin
Answer:
C. Stabilizing selection
Explanation:
Natural selection, is of three different types namely: disruptive selection, directional selection and stabilizing selection. Disruptive selection occurs when the two extremes of a population are being favored over the average or intermediate.
Directional occurs when one extreme of a population is favored. However, in STABILIZING SELECTION, the average or intermediate population is favored over both extremes of a population. Example is when the average-sized beaks of a bird population is being favored over the long and short ones (extremes).
Answer:
the answer is stabilizing.

Human blood types have 3 alleles: A, B, and O. A and B are codominant, while o is
recessive to A and B.
If a person has the genotype AO what is their blood type?
a. O
b. B
C. AB
d. A
Answer:
D
Explanation:
A genotype of AO means that the person only has the A antigen, so their blood type is just A. AO and AA have different genotypes but the same blood type.
