Answer:
lipids
Explanation:
Answer:
lipids
Explanation:
macromolecules are large molecules that are formed by the joining of smaller units. Lipids fit that description, but they aren't polymers because they are made up of smaller units of different kinds (like glycerol and fatty acids) rather than monomers that repeat themselves
Using evidence from the video, describe three characteristics of life that Archaea bacteria have.
A image of Archaea micro organism within the video confirmed that the body is made of a unmarried cellular, and has a described boundary. Scientists also realize that it reproduces by transmitting its genetic facts because there's proof of Archaea genes in our DNA nowadays.
The three traits of lifestyles that Archaea micro organism have are:not unusual characteristics of Archae bacteria known to this point are: (1) the presence of a feature of tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan mobile partitions, in most instances, in preference to a huge protein-wealthy coat; (three) the formation of ether-related lipids formed through phytanyl chains.
what's the difference among micro organism and archaea micro organism?Like micro organism, archaea have no inner membrane however both have cellular partitions and use flagella for swimming. Archaea differs from the reality that their cell wall does not include peptidoglycan and that the cell membrane makes use of ether-linked lipids rather than an ester connected to lipids in micro organism.

Place the steps of biofilm formation in the correct order: 1. Quorum sensing and the establishment of the extracellular matrix commences as microbes attach more stably. 2. Surface (substratum) is preconditioned by environmental molecules. 3. Biofilm matures and some microorganisms escape to the planktonic state. 4. Microbes attach and detach from the preconditioned surface.
Answer:Step order:
2. The surface (substrate) is preconditioned by environmental molecules.
4.Microbes bind and detach from the preconditioned surface.
1.Quorum detection and extracellular matrix establishment begins as microbes bind more stably.
3. The mature biofilm and some microorganisms escape the planktonic state.
Explanation:
The biofilm is a highly complex structure where many microorganisms coexist, compete, reproduce, feed, within a micro-system with many ideal conditions for each microorganism that is housed in it.
The biofilm is resistant to non-selective antimicrobials, that is, to disinfectants such as sodium hypochlorite, chlorhexidine, among others.
Evidence was also presented that they are resistant to selective antimicrobials such as antibiotics, that is why they have great virulence factors or potential to trigger pathology.
The solution to destroy a biofilm is mechanical sweeping, with brushing as it happens on our teeth or even with the catheter cleaning brushes that are used (in addition to the sterilization methods).
This biofilm presents separate colonies in its interim with a fluid that it travels transmitting signals, food, toxins, resistant factors between these different types of microorganisms. This fluid and this communication between them is called quorum sensing and not all microorganisms tolerate it.
Many microorganisms compete with each other for the medium, an example is streptococcus mutating in the dental biofilm, which generates an acidic medium by metabolizing carbohydrates within the biofilm, thus generating that those bacteria that live in neutral or alkaline ph cannot reproduce and die.
The biofilm can be contained by bacteria, viruses, fungi and even parasites, but what they all have in common is that they have the ability to reproduce on an inert surface such as catheters, dental surfaces, silicone hoses.

In a population of 200, 86 individuals express the recessive phenotype. What percent of the population would you predict would be
heterozygous?
A. 65%
B. 55%
C. 35%
D. 45%
Answer:
The correct option is;
D. 45%
Explanation:
From the Hardy- Weinberg law, we have;
p² + 2·p·q + q² = 1
p + q = 1
Where:
p = Dom inant allele frequency in the population
q = Recessive allele frequency in the population
p² = The percentage of individuals in the population that are hom ozygous dominant
q² = The percentage of individuals in the population that are homo zygous recessive
2×p×q = The percentage of hete rozyous individuals in the population
The number of individuals that express the recessive phenotype = 86
The number of individuals in the population = 200
The percentage of individuals that express the recessive phenotype, q² = 86/200 = 0.43
Therefore;
q = √0.43 = 0.656
p + q = 1
p = 1 - q = 1 - 0.656= 0.344
∴ The frequency of individuals that express the do minant phe notype, p = 0.344
The percentage of heterozyous individuals in the population = 2×p×q × 100 = 2 × 0.656 × 0.344 × 100 = 45.15% ≈ 45%

Which characteristic describes the whale but not its food source, the phytoplankton? The whale is heterotrophic. The whale has cell walls. The whale is unicellular. The whale is a prokaryote.
Answer:
A. The whale is heterotrophic.
Explanation:
The whale is an aquatic animal that is heterotrophic in nature. Heterotrophic means that this animal lacks the ability to manufacture its own food because it depends on plants and animals as a source of food energy. Since the Whale is dependent on phytoplankton for food, this means that it is not a producer of food and as such is heterotrophic.
Phytoplankton is a marine alga. Algaes are prokaryotes and this means that they are unicellular animals without a membrane-bound nucleus. The Cell wall is mostly a characteristic of plants. So the first option is a perfect description of the whale and not its food source which is the phytoplankton.
Answer:
ExplanationThe whale is heterotripic

Mention five similarities between art and philosophy.
Please this is URGENT!! I'll thank u so much if u help me.
Answer:
The five major similarities between the given instances are described below.
Explanation:
Art seems to be about men's job of making things or even just meanings. Philosophy should be about what life, reality, and wisdom represent.Philosophy couldn't be incorrect, just as art can't be that bad. That is an incoherent term. The argument that theory goes around through communities or never comes to a satisfactory conclusion has always been the main topic including its argument. That's only because philosophy becomes interpreted as if it were science rather than art.Art and Philosophy will say, I'm making this. Those would be the ideal illustration of the intelligence of man.Art seems to be an undertaking that aims at creating something aesthetically intriguing and that would be valued for its attractiveness or expressive strength. Philosophy approaches art from such a situational-perspective, i.e., attempting to ascertain whatever was rather than concentrating on a single piece of art or observing general trends.

Which is not something that occurs in translation? A codon and an anticodon pair. A peptide bond is created. A molecule of mRNA is formed. An amino acid is added to a polypeptide.
Answer:
A molecule of mRNA is formed.
Explanation:
Translation is the second process that occurs in gene expression. It is the process by which the information encoded in the mRNA transcript is used to synthesize a protein.
The mRNA nucleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. Translation, which occurs in the ribosomes (cytoplasm), reads the codon with an anticodon using the complementary base pairing rule i.e. A-U, G-C. This means that a CODON-ANTICODON pairs.
The anticodon carries a corresponding amino acid to the polypeptide sequence. A peptide bond is formed when two amino acids joins together in a condensation reaction.
Note: A molecule of mRNA is formed during transcription
Answer:
A molecule of mRNA is formed.

Describe how the water cycle moves water between the tree, the lake, and the sky in the picture below. Describe at least three of the water cycle processes you have learned about in the course. (10 points)
Answer:
The heat from the sun warms the water in the lake which evaporates and turns into water vapours. The water in the tree also rises into the atmosphere through a process, transpiration.
The water vapours rise into the atmosphere and forms clouds.
The water vapours in the clouds than condense into liquid water. Soon they'll get heavy and the water will fall down as rain, sleet, or snow.
Some of the rainwater sinks into the ground and is taken in by the roots of trees and plants.
This process keeps going on and on, and the water keeps shifting between the lake, tree and the sky.

A. C6H1206 and 02
B. C2H4O2 and H20
C. C2H4O2 and 02
D. C6H1206 and H20
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
