The process is identified by number 1 in the diagram and where in the cell does this process occur is translation, at the ribosome. Thus option 3 is correct.

Translation is defined as the process by which a messenger RNA (mRNA) molecule's sequence is converted into an amino acid sequence during protein synthesis.

It is also be defined as when DNA is converted to RNA in the cell's nucleus, the process through which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. Gene expression refers to the entire process.

Initiation, elongation, and termination are the three phases of an mRNA molecule's translation by the ribosome.

Thus, the process is identified by number 1 in the diagram and where in the cell does this process occur is translation, at the ribosome. Thus option 3 is correct.

Answer:

B. 3.12 x [tex]10^{-3}[/tex] m

Explanation:

From the given picture, it can be deduced that;

the diameter of the image of lumen = 25.0 mm

                                                      = 25.0 ÷ 1000

                                                      = 0.025 m

And,

magnification = [tex]\frac{diameter of the image of lumen}{actual diameter of lumen}[/tex]

But magnification = 8,and diameter of the image of lumen = 0.025 m.

So that;

8 = [tex]\frac{0.025}{actual diameter of lumen}[/tex]

⇒ actual diameter of lumen = [tex]\frac{0.025}{8}[/tex]

                         = 0.003125

Actual diameter of lumen of the blood vessel is 3.12 x [tex]10^{-3}[/tex] m.

Answer:

Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes.

Explanation:

The main functions of a photosystem are: they are a functional unit of photosynthesis, and they trap or release light.

Plants, algae, and cyanobacteria all have thylakoid membranes that contain photosystems. These membranes are found in the cytoplasmic membrane of photosynthetic bacteria as well as the chloroplasts of plants, algae, and other vascular organisms. The PSI and PSII subtypes of photosystems exist.

The functional components of photosynthesis are called photosystem, and they are identified by specific pigment organization and association patterns.

Therefore, the photosystem is responsible for absorbing and transferring light energy, which entails transferring electrons. The thylakoid membranes contain photosystem in terms of physical location.

to intimidate his predators

Explanation:

The reasons would a male peacock spread his tail feathers to intimidate rival males. Thus, option E is correct.

For natural selection to occur, four basic conditions are necessary:

Natural selection has been known as the evolutionary mechanism proposed by Charles Darwin, who stated that the environment acts as a selector of characteristics, perpetuating the organisms best able to survive in a given place.

Genes that encode bright feathers give an advantage to the male peacocks over other males which do not have an equally bright assortment of feathers, increasing the individual's reproductive success. This results in the advantageous genes such as of bright feathers recurring over the generations and remaining a part of the gene pool.

Therefore, The reasons would a male peacock spread his tail feathers to intimidate rival males. Thus, option E is correct.

Answer:

Explanation:

In facilitated diffusion, substances move into or out of cells down their concentration gradient through protein channels in the cell membrane. Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient.

Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.

Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient , using energy released during respiration .

Explanation:

Blood type is determined by the  ✔ antigens  on the blood cells.

✔ Antibodies  attack foreign blood that does not contain the same antigens.

Blood type is an illustration of codominance.

Blood group also known as blood type refers to classification of blood on the basis of the absence and presence of antibodies and inherited antigenic components on the red blood cells surface. These antigens may be:

The blood type in humans is an example of codominance. In codominance, neither of the allele can inhibit the expression of the other allele. One of the example is the ABO blood group in humans. In this, both the alleles A and  B are expressed.

Therefore, if a person is inheriting allele A from the mother and allele B from the father, he or she will have the blood type AB.

Answer:

The paper takes more time to fall than the piece of thermocol because it experiences a greater air resistance than the thermocol.

The thermocol takes more time than the piece of plastic because it experiences a greater air resistance.

The piece of paper can be made to fall faster than all of them and hit the ground faster by crumpling it and then giving it an initial velocity by throwing it downwards.

Explanation:

Objects falling freely due to the force of gravity alone are accelerated downwards at a constant value 9.8 m/s². This acceleration due to gravity is constant for all objects on the earth's surface and is independent of the mass of the objects.Therefore, when objects are release from the same height and allowed to fall freely under gravity, they are accelerated downwards to the same extent and are expected to hit the ground at the same time. However,due to the resistance of the air through which the objects are falling, they may hit the ground at different times depending on the shape of the falling objects.

Objects which have a greater surface area or volume per unit mass will experience a greater air drag or resistance and therefore, will take a longer time than objects of similar mass with a smaller volume or surface area.

The paper has a greater surface area per unit mass than the piece of thermocol, therefore, it takes more time to fall than the piece of thermocol because it experiences a greater air resistance than the thermocol.

The thermocol has a greater surface area per unit mass than the piece of plastic, therefore, it takes more time than the piece of plastic because it experiences a greater air resistance.

The piece of paper can be made to fall faster than all of them and hit the ground faster by crumpling it, thereby reducing its surface area per unit mass it and then giving it an initial velocity by throwing it downwards.

Answer:

From the ocean to the land. just took the quiz.

Explanation: a p e x

During the day, the air above land in coastal regions warms up more quickly and starts to rise, hence option A is correct.

As the warm air rises, a low-pressure region develops on the surface, enabling air from the sea to enter. As a result, the wind blows from the sea to the land during the day.

Predominant winds often blow east-west rather than north-south, especially in the afternoon when the land is being heated by the sun to its maximum.

the Coriolis effect causes wind systems to twist counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere most frequently in the spring and summer.

Therefore, because of the greater temperature differences between the ocean and nearby land, hence option A is correct.
