Which of the following best explains how the phospholipid bilayer of a transport vesicle contributes to cellular functions?
A
The phospholipid bilayer allows the vesicle to fuse with the Golgi apparatus and the plasma membrane, allowing the exocytosis of proteins.
B
The phospholipid bilayer physically connects the nuclear envelope to the rough endoplasmic reticulum, thus increasing the rate of transcription and translation.
С
The phospholipid bilayer of a transport vesicle contains chemicals that digest the proteins made in the rough endoplasmic reticulum.
D
The phospholipid bilayer contains enzymes that catalyze the conversion of hydrogen peroxide to water and oxygen.
Answer:A
Explanation:
The statement 'the phospholipid bilayer allows the vesicle to fuse with the Golgi and plasma membrane, allowing exocytosis' explains how the phospholipid bilayer of vesicles contributes to cellular functions (Option A).
The endomembrane system is an interconnected network of phospholipid-based membranes which includes the Golgi and plasma membrane.This system (endomembrane system) is used by cells to transport substances to the extracellular medium. Transport vesicles are vesicles that help to move proteins and other biomolecules from the interior of the cell to the extracellular medium.The process by which transport vesicles fuse with the cell membrane to release their components to the extracellular environment is called exocytosis.In conclusion, the statement 'the phospholipid bilayer allows the vesicle to fuse with the Golgi and plasma membrane, allowing exocytosis' explains how the phospholipid bilayer of vesicles contributes to cellular functions.

How many molecules are in 0.585 mole of lactic acid?
Answer:
There are 3.523x10²³ molecules in 0.585 moles of lactic acid.
Explanation:
To solve this problem we need to use Avogadro's number, which is defined as the number of molecules (or atoms, in the case of an element) that are in 1 mole:
There are 6.023x10²³ molecules in 1.0 mole
With that information in mind, we convert lactic acid moles into molecules:
0.585 mol * 6.023x10²³ molecules/mol = 3.523x10²³ moleculesWhich condition is important for a temperature inversion?
two layers of warm air
two layers of warm air, one on top of the other
a layer of warm air over a
layer of cold air
a layer of cold air over one of warm air
Answer:
the answer is that"a layer of warm air over a layer of cold air" which can be caused by factors like formation of fronts, scattering, advection.
The condition important for a temperature inversion is a layer of warm air over a layer of cold air. Hence option C is correct.
What is temperature?Temperature is defined as any scale used to represent how hot or cold something is, including the Celsius and Fahrenheit scales. Food, beverages, agriculture, and medical care for both people and animals all depend heavily on temperature. Temperature also frequently affects our general health in a number of ways. In facilities used for medical cold storage, maintaining optimum temperatures is crucial.
The usual behavior of temperature in the troposphere is reversed by a phenomenon known as temperature inversion. A layer of warm air sits on top of the layer of cold air beneath this meteorological occurrence. It is brought on by static atmospheric circumstances, while it can also be brought on by air moving horizontally or vertically.
Thus, the condition important for a temperature inversion is a layer of warm air over a layer of cold air. Hence option C is correct.

chemical composition of the Rough endoplasmic reticulum
Answer:
The rough endoplasmic reticulum consists of two dimensional flattened sacs formed from phospholipids and ribosomes.
Explanation:
Genes within DNA are expressed through transcription and translation of the genetic code.
The rough Er contains important machinery in gene expressions, Ribosomes embedded in a lipid membrane. These are small sub cellular organelles that carry out a specific function of protein manufacturing and modulation. They contain the translocon complex, integral to the translation process
The endoplasmic retuculum consists of folded phospholipid membrane sheets or cisternae- these are mainly two dimentional, and form flat sacs.These provide small specific environments from the cytosol in the cytoplasm- they span the entire cytoplasm.
Why are stop and start codons signals necessary for protein synthesis
Answer:
The start and stop codons —part of the mRNA's genetic code— are necessary because they indicate the exact length a protein should have.
Explanation:
The sequence of bases contained in an mRNA strand is the genetic code that allows the synthesis of specific proteins. The mRNA information is organized into triplets or codons, whose function is :
To code the amino acids that will be incorporated into the protein to be synthesized. To establish the sequence of amino acids of a peptide or protein, which depends on the sequence of codons formed by nitrogenous bases. To mark the beginning of the synthesis, with the starting codon that, in addition, codes the amino acid Methionine. Establish the end of the synthesis, through the three stop codons, UAA, UAG and UGA.The importance of the start and stop codons is that they establish the exact length that, genetically established, a specific protein must have.

When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously as the hydrogen peroxide (H2O2) decomposes into water (H2O) and oxygen (O2) This range change in reaction rate suggests
that liver is a substrate for hydrogen peroxide
that liver contains lots of germs
the liver contains an enzyme that breaks down hydrogen peroxide
that hydrogen peroxide is a powerful enzyme
Answer: C
Explanation:
Catalyst is one enzyme from liver that breaks down harmful hydrogen peroxide into oxygen gas and water
When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously as the hydrogen peroxide decomposes into water and oxygen. This suggests the liver contains an enzyme that breaks down hydrogen peroxide. Thus, the correct option is C.
What is Catalase?Catalase is a common enzyme which is found in nearly all living organisms which are exposed to oxygen gas. Catalase is a key enzyme which uses hydrogen peroxide, a nonradical Reactive Oxygen Species, as its substrate. Catalase enzyme is responsible for the neutralization through decomposition of hydrogen peroxide, thereby maintaining an optimum level of the molecule in the cell system which is also essential for the cellular signaling processes.
Catalase is an enzyme which causes or speeds up a reaction without being affected during the reaction. The enzyme catalase speeds up the breakdown of hydrogen peroxide into water and oxygen gas.
Therefore, the correct option is C.

Nucleic acids are made of fundamental units called base pairs along with sugar and phosphate groups.
The base pairs are joined unitedly by a hydrogen bond.
The correct answer is:
Option b. 1 in 100,000
This can be explained as:
In the eukaryotic cells, there is a chance once in 10⁵ polymerized nucleotides to have an error.The errors are repaired by the DNA repair mechanism and the correct nucleotide is added.Therefore, once in 10,000 base pairs are matched wrongly before being repaired by DNA polymerase.

Breakdown of dead/decomposing materials into ammonia?
Answer:
Breakdown of dead materials into ammonia occurs due to decomposers.
Explanation:
Decomposers are the organisms which are responsible for the breakdown of dead bodies of plants and animals produces ammonia by consuming the nitrogen present in that dead body of plant and animals through the process of ammonification. The ammonium produced is then converted into nitrates by the nitrifying bacteria and this nitrates is used by the plants for making amino acids and enzymes.

1 All of the following processes move carbon out of the biosphere and into the atmosphere, geosphere, or hydrosphere except:
a:respiration b:photosynthesis c:excretion d:decaying
Answer:
photosynthesis
Explanation:
it takes carbon into the biosphere
Photosynthesis doesn't move carbon out of the biosphere instead takes up carbon and uses it for energy production in plants. Therefore, option (B) is correct.
What is photosynthesis?During the process of photosynthesis, plants draw carbon dioxide (CO2) and water (H2O) from the atmosphere and the soil respectively. Within the plant cell, water undergoes oxidation, which results in the loss of electrons, whereas carbon dioxide undergoes reduction, which results in the accumulation of electrons. Because of this, the water is converted into oxygen, and the carbon dioxide is converted into glucose.
Photosynthesis powers plant growth. This mechanism transforms carbon dioxide, water, and soil minerals into cells. Plants generate oxygen and nourishment.
Therefore, option (B) photosynthesis move carbon out of the atmosphere and into the biosphere.
