What would happen if the cell membrane only had 1 layer of phospholipids?
Answer:
If phospholipid bilayer diffusion is normally negligible, there will be tissues (largely lacking in transporters that may be expressed elsewhere) which, despite the relative functional similarity of their phospholipids, are very poor at taking up drugs: the blood–brain [33], blood–testis [34], and blood–retina
Explanation:
The cell membrane has two layers for phospholipids because of its hydrophobic and hydrophilic nature as the cell has to give entry to both the molecules therefore the bi layer makes this the possible option.
What is the reason for more stability for the 1 layer of phospholipids ?The single layer of phoshpholipids makes it more easier to maintain phospholipids' stability because the membrane phospholipids will interact with the hydrocarbons of oil molecules via van der waals interactions.
The basic cell structure is well protected with the help of membrane and the various transportation activities along with the cellular processes takes place via the phospholipids because of their hydrophobic and hydrophilic interactions between the molecules.
Thus, 1 layer will definitely add on stability but the interaction and cellular activities will take place through phospholipids interactions.

Does DNA control RNA?
Answer:
RNA is usually synthesized from DNA.
Answer:
RNA is usually synthesized from DNA. The synthesis usually requires one or more enzymes like RNA polymerase. The DNA strand is used as a template or guide on which the RNA is formed
In reality, there is much more to the RNA story. The central dogma of molecular biology suggests that DNA maintains the information to encode all of our proteins, and that three different types of RNA rather passively convert this code into polypeptides.

aminoacyl-trna synthetase is an enzyme whose function is to _____.
Answer:plays a critical role in protein synthesis,
Explanation:
Aminoacyl-tRNA synthetase is an enzyme whose function is to attach the appropriate amino acid to its corresponding transfer RNA (tRNA) molecule, creating an aminoacyl-tRNA complex that will be used in protein synthesis.
What is Aminoacylation?Aminoacylation, also known as tRNA charging, is a biochemical process in which an amino acid is attached to its corresponding transfer RNA (tRNA) molecule. This process is catalyzed by the enzyme aminoacyl-tRNA synthetase, which recognizes the specific amino acid and the corresponding tRNA molecule that carries the anticodon sequence for that amino acid.
Aminoacylation is a crucial step in the process of protein synthesis, as the charged tRNA molecule brings the amino acid to the ribosome during translation, allowing the amino acid to be incorporated into the growing polypeptide chain.
The accuracy and efficiency of aminoacylation are critical for ensuring that proteins are correctly synthesized, as errors in aminoacylation can lead to the misincorporation of amino acids and the synthesis of non-functional or improperly folded proteins.

Based on the key you created, do you think some of the organisms are more closely related than others? Explain your answer.
Part 1 was this:A dichotomous key works on the principle of asking yes-or-no questions about the organism. To identify it, the answers for that organism are then compared to existing organisms to identify it. Prepare a list of four to five questions about each of the organisms listed below to help you create your own key. For each question, make sure the answer isn’t the same for all four organisms.

Explanation:
Part E: Yes, I think that there are some closely related species of organisms that cannot be identified with a dichotomous key. Dichotomous key is used to classify objects or organisms based on its physical characteristics. Because of that limitation, there are species that may be related according to the dichotomous key but are in fact not or its relation is very minimal whereas there are organisms that may seem unrelated based on their physical characteristics but are actually from the same ancestors.
How is the 3D model you are constructing similar to a real cell membrane? How is it different?
Answer:
It is similar because it is the same structure as a real cell membrane. It is different cuz it is not the same size, color and texture.
Hope this helps
Explanation:
This is how a model plant cell is created. You'll need a plastic box, a tiny sandwich bag that can seal and is filled with water, cling film, some peas, either frozen or fresh, some water colored green with food coloring if you have any, and a reliable grape.
What 3D model constructing to a real cell membrane?The fluid mosaic theory postulates that phospholipids, cholesterol, and proteins are among the numerous, constantly moving elements that make up the cell membrane.
The cell membrane is helped in maintaining its role as a partition dividing the inner and outside cell environments by this movement.
What enters and leaves the cell is governed by the cell membrane. The cell membrane is comparable to a screen door in that it keeps things out while allowing air in.
Therefore, It resembles an actual cell membrane in structure, which is why it is comparable. It differs because it has a different size, color, and feel.

2. Two greenhouse gases, carbon monoxide and carbon dioxide, have increased Earth's temperatures due to the burning of fossil fuels. This phenomenon is known as
global warming
climate change
greenhouse effect
positive feedback
Answer:
Explanation:
It doesn't mean that temperatures everywhere are hotter. The angle at which sunlight hits Earth is one of the most important factors impacting the average temperatures in a region. Higher angle (more direct) sunlight warms Earth more effectively. Earth's axis is tilted by ~23°.
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Which option describes how the absolute age of a fossil is commonly determined?
The carbon-14 in a fossil breaks down over time. The remaining amount of carbon-14 in the
fossil can be used to calculate its age.
The carbon-12 in a fossil breaks down over time. The remaining amount of carbon-12 in the
fossil can be used to calculate its age.
Once the organism is dead, carbon-12 starts to accumulate. The existing amount of carbon-12
in the fossil can be used to calculate its age.
Once the organism is dead, carbon-14 starts to accumulate. The existing amount of carbon-14
in the fossil can be used to calculate its age.
The half-life of an isotope is useful to determine how much time has an organism been dead or how much isotope is left in the organism. Option A) The carbon-14 in a fossil breaks down over time. The remaining amount of carbon-14 in the fossil can be used to calculate its age.
What is an isotope half-life?
When talking about an element or isotope's half-life, we refer to the time it takes for the element's mass to be reduced to its half, while the other half becomes its daughter form.
The half-life values are useful to determine the age of dead matter or for how long that matter has been dead.
Carbon 14 is a radioactive carbon isotope. It is used in radiocarbon dating techniques to estimate the age of fossils. This is a reliable technique used for dating organic samples that are less than 50,000 years old.
The radioactive C14 has a half-life of 5730 years. It means that an organism that has been dead for 5730 years has half the C14 amount or concentration than the same organism had when it was alive.
The correct option is A)
The carbon-14 in a fossil breaks down over time. The remaining amount of carbon-14 in the fossil can be used to calculate its age.

The method used to determine the absolute age of a fossil is called radiometric dating. Radiometric dating relies on the fact that radioactive isotopes decay at a predictable rate over time. Carbon-14 is a radioactive isotope that is commonly used in radiometric dating. When an organism dies, it stops taking in carbon-14, and the carbon-14 that was in the organism begins to decay. The remaining amount of carbon-14 in the fossil can be used to calculate its age.
Therefore the answer is option a.
The carbon-14 in a fossil breaks down over time. The remaining amount of carbon-14 in the fossil can be used to calculate its age.
