The question is: how does the color of a
candle affect the time it takes the candle to
burn. Time measured in minutes. height
measured in centimeters at regular
intervals of time
and u need to solve what's a indecent
variable, Contants and A dependent
variable
1.In actuality, a candle's color has little to no impact on how quickly it burns. In rare situations, candle color can actually make a candle burn hotter, which causes colored candles to burn more quickly.
2.For every 28 g of wax used, smaller candles with smaller wicks will burn for 7 to 9 hours. Wax is consumed more quickly by larger candles with larger wicks. For every 28 g of wax used, the larger wicks can be anticipated to produce 5 to 7 hours (420 minutes).
3.A candle burns down to a smaller amount of wax than it did at the beginning. This is due to the wax's oxidation, or burning, in the flame, which results in the release of water and carbon dioxide, which dissipate in the surrounding air and produce light and heat. Thus height decreases.
The variable that the experimenter willfully modifies or manipulates is known as an independent variable. The cause, input, or action during the process is the independent variable.

If a bacterial species is not susceptible to an antibacterial drug at the concentration present in a particular disk, does that necessarily mean the species is completely resistant to the drug? Explain your answer
If a bacterial species is not susceptible to an antibacterial drug at the concentration present in a particular disk,it does not necessarily mean the species is completely resistant to the drug.
What is an Antibiotic?These are chemical compounds which kill or slow down the growth of bacteria through various factors and mechanisms.
Some bacterial species have become susceptible to some antibacterial drug as a result of mutations which occurs during the process of replication and occurs in the genetic material known as the DNA.
Bacterial species not being susceptible to an antibacterial drug at the concentration present in a particular disk means it is only at that exact point in the DNA which is therefore the reason why it it does not necessarily indicate complete resistance to the drugs.

Although it is far high on the main sequence, a more massive star starts its existence in a similar way, with hydrogen being transformed to helium.
Because of the biochemical and kinetic impression they leave on the environment, massive stars are important forces in the existence of the universe. They are major contributions to the spectrum of galaxies and excellent tracers of stellar evolution in the expansion Of the universe due to their extreme brightness. Understanding the universe requires a precise description of huge stars. Due to their production of powerful stellar winds, intense radiation, and supernova explosions—features essential for the development of galaxies—these stars have a significant impact on their surroundings.
Massive stars, despite being very few in number, have a fundamental impact on the interstellar space and the history of the galaxy because they ionise the encircling gas and deposit potential power first through powerful stellar winds, then as supernovae.

The theory of the new corona virus's transfer from bats to people is covered in the explanation that follows.
The severe acute respiratory syndrome coronavirus 2 was produced as a result of cross-species transmission and is the culprit behind COVID19 (SARS-CoV-2). Coronaviruses are a large family of viruses that may infect a variety of hosts.
The host ACE2 protein and TMPRSS2 cleavage of the surface (S) protein are required for SARS-CoV-2 entrance. ACE2, a species-specific barrier, may prevent the bat-to-human coronavirus from spreading across species boundaries. Bats were confirmed as SARS-natural CoV's hosts by a molecular analysis, and they were also linked to the genesis of MERS-CoV.
A novel coronavirus called the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) evolved as the cause of COVID19 as a result of interspecies transmission.
Coroviruses are a large family of viruses that may infect a variety of hosts. For SARS-CoV-2 entrance, the surface (S) protein must interact with the host ACE2 protein and TMPRSS2 must be cleaved.
The species-specific barrier ACE2 may stop the bat-to-human coronavirus from spreading. A molecular analysis established bats as the SARS-natural CoV's hosts and linked them to the establishment of the MERS-CoV. Given the genetic resemblances between the SARS-CoV-2 strain and the bat RaTG13 CoV strain, it is believed that the most recent outbreak was caused by bats.
Compared to the human TMPRSS2 sequence, the pangolin ACE2 amino acid sequence has a greater evolutionary distance from bats and a lower evolutionary distance from humans. When comparing SARS-CoV and SARS-CoV-2 origins, the civet, the main intermediate host of SARS-CoV, has lesser ACE2 evolutionary divergence with humans than pangolin. The pangolin has evolved into an appropriate host for intermediate SARS-CoV-2 leap and entrance from bat to human as a result.
Phylogenetics: What is it?The study of links and evolutionary histories between or among groups of species is known as phylogenetics.
