In prokaryotic cells, the ribosomes:
O A. synthesize proteins
O B. synthesize nucleic acids
O C. synthesize sugars
O D. synthesize fatty acid
Answers
Answer:
[tex]\boxed {\boxed {\sf A. \ Synthesize \ proteins}}[/tex]
Explanation:
The ribosomes are small organelles made of RNA and proteins. Its function is the same in both prokaryotic and eukrayotic cells: protein synthesis.
The process begins in the nucleus. The DNA and genetic information is housed here. Certain sections are transcribed and copied to make messenger mRNAs that can fit through the nucleus and pores to travel out to the ribosomes.
The ribosomes use the mRNA in a process called translation. They match each set of 3 nucleotides (a codon) in the mRNA to 1of 20 different amino acids. A special sequence of amino acids forms, the molecule folds, and a protein is formed.
So, a ribosome is the main site for protein synthesis and the correct choice is A.

Answer:
The Natural Step Framework is a methodology for successful organisational planning. It is based on systems thinking,
recognizing that what happens in one part of a system affects every other part. We begin by understanding the broader system
within which problems occur and the principles governing success within that system These principles for success then
provide a practical set of design criteria that can be used to direct social, environmental and economic actions, developing

describe how the force of gravity from Earth could affect nearby Apollo asteroids and explain how the effect of Earth’s gravity could change the orbital motion of an Apollo asteroid.
Answers
Gravity pulls objects toward Earth at a rate of 9.8 m/s2. Weight is the result of gravity's pull on a mass on Earth's surface.
The force of gravity from the Earth could affect nearby the Apollo asteroids and this gravitational force is responsible for pulling the objects towards itself which could change the orbital motion of an Apollo asteroid.
What is the Apollo asteroid?Apollo asteroids are also called as the near-earth asteroids. These are a major source of the meteorites which occasionally fall to the earth. Asteroids with the orbits that approach the earth, are passing inside the perihelion of the Mars, and these are called as Amors. Those that cross the orbit of the earth are called as the Apollo asteroids.
Gravitational force is the force which pulls all the objects in the universe towards each other on the planet and in its orbit. On the Earth, gravity pulls all the objects downward towards the center of the planet.

A scientist is studying the passive movement of a molecule into a cell. He measures the rate at which this chemical moves into the cell, as a function of its external concentration. The chemical's rate of movement is directly proportional to the extracellular concentration but eventually reaches a transport maximum. What type of transport seems to be used by this molecule
Answers
Answer:
The correct answer is - facilitated diffusion.
Explanation:
First let's understand about FACILTATED DIFFUSION.
Normally diffusion occurs from higher concentration to lower concentration area, that means, along the concentration gradient.
In the process of FACILTATED DIFFUSION, for a substance to get diffued, it should occur with help of a protein in the membrane. Of course this process occurs with out consuming energy in the form of ATP therefore its a PASSIVE process.
Now lets understand the term TRANSPORT MAXIMUM, here lies the answer of above question.
Transport maximum is a condition when there is no more movement of chemicals/ any particles via mebrane because of SATURATION of available proteins required to transport chemicals across the membrane. As there are no more proteins available to transport chemicals across membrane, diffusion wont takes place anymore untull those proteins are regenerated.
Therefore as mentioned in question that CHEMICAL-A reached transport maximum. This says that it is transported by a process called facilitated diffusion.

Answers
Answer:
a. pass readily through a membrane's lipid bilayer
Explanation:
Small, nonpolar hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer.
Small, nonpolar hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer. Therefore, the correct option is option A.
The hydrophilic (water-loving) heads of the two layers of phospholipids in the lipid bilayer face outward towards the aquatic surroundings, while the hydrophobic (water-hating) tails point inward towards one another. The hydrophobic tails of phospholipids share characteristics with nonpolar hydrophobic compounds like fatty acids. These tiny molecules can easily dissolve in the hydrophobic area of the lipid bilayer because of their hydrophobic nature.
Therefore, the correct option is option A.

Individuals in a population of purple people earters are polymorphic at a single locus that leads to variation in purple people eater pup viability. 45% of the pups with genotype PP are viable, 54% of pups with genotype Pp are viable, but only 4% of pups with genotype pp are viable. What model of natural selection best fits these data
Answers
Answer:
The correct answer is - overdominance.
Explanation:
In the given question, genotype Pp is a heterozygote condition that has a 54% survival rate or fitness thus these individual people get more chance of mating and increase in number as compared to the other two conditions of PP or pp traits where PP has 45% survivability, less than heterozygous condition and more than pp that has only 4% rate.
It results in a normalizing selection model of natural selection as a moderate trait, that is heterozygote, is selected. Thus, the selection of overdominance which means heterozygote condition produces a better phenotype than PP or pp parents is heterosis.

What will happen to a plant cell placed in distilled water?
The cell will become flaccid due to the cell membrane.
The cell will become turgid due to the cell wall.
The cell will lysis due to the cell membrane.
The cell will burst due to the cell wall.
Answers
Answer:
the cell will become turgid due to tge cell wall
Explanation:
when a plant cell is placed in distilled water the water will move in the solution inside the cell is hypertonic to the distilled water serrounding the cell but it will not burst it producr turgor pressure keeping the plant upright
if a plant cell is placed in distilled water, and distilled water has a very low concentration of solutes the cell will become turgid due to the cell wall, hence option B is correct.
How distilled water affect the plant cell?This is because distilled water has a very low concentration of solutes and a high concentration of solvent, making it a hypotonic solution in comparison to the intracellular environment.
To put it another way, we can say that the solute concentration of When a plant cell is placed in distilled water, it becomes turgid.
This is due to the fact that it osmotically absorbs water from the hypotonic distilled water, causing the cytoplasm of the plant cell to enlarge and firmly press up against the cell wall.
Therefore, distilled water has a very low concentration of solutes, so cells will become turgid.
