A. From the ocean to the land
B. From the sun to the land
O O O O
C. From the land to the ocean
D. From the land to the sun
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.
What is the direction of the wind?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.

What are the principles of natural selection?For natural selection to occur, four basic conditions are necessary:
Reproduction: organisms must reproduce to form new generations;Variability: there must be differences between individuals in the population;Heredity: Descendants must inherit characteristics from their parents.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.

This picture shows a cross-section of a blood vessel. The diameter of the
lumen in Figure 10 is 25.0 mm. What is the actual diameter of the lumen of
this blood vessel?
lumen
magnification X8
3.1 x 10-2m
3.1 x 10-3 m
O 2.0 x 10-2 m
2.0 x 10-3 m
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.
Make a claim about whether the sun's rays are mechanical or electromagnetic waves. Summarize evidence to support this claim and explain your reasoning.
Answer:
Se explanation
Explanation:
Mechanical waves are waves that require a material medium for propagation e.g sound waves and waves on a spiral spring.
Electromagnetic waves do not require a material medium for propagation. They can travel through space.
The light and heat of the sun are far away in outer space yet they reach us on earth. There is no intervening medium between the earth and the sun that conducts its rays to the earth. As a result of this, we can conclude that the rays from the sun are electromagnetic waves.
how does climate and vegetation vary with latitude and elevation?
Answer:
Climate and vegetation vary with latitude and altitude of an area. Latitude measures distance from the equator; altitude measures elevation above sea level. ... Deserts have little precipitation and little vegetation. They are found in tropical, temperate, and Polar Regions.
The climate and vegetation may significantly vary with the latitude and elevation. This is because as elevation increases the temperature decreases gradually that do not favor the actual growth of vegetation.
What is Climate?Climate may be defined as a type of weather conditions that are persuading in any geographical location for a long period of time. In a more simple sense, it is characterized as the long-term pattern of weather in a particular area.
Latitude estimates the distance from the equator part of the earth and goes through the tropical, temperate, and colder regions of the earth. The vegetation is typically reduced with increasing the altitude or elevation with respect to the sea level.
It may also be noticed that the vegetation may alter with respect to the geographical location of the whole earth. It was never found to be completely absent.
Therefore, the climate and vegetation may significantly vary with the latitude and elevation.

what is the function of photosystems
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.
What is a photosystem?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.

Answer:
methionine-proline-glycine-leucine-stop
Explanation:
Using an amino acids chart, you can line up the 3 bases in each section to find the protein chain that corresponds. The stop at the end marks the end of protein synthesis, which ends the sequence.
The compound comprising carboxylic and amino groups is called amino acids. They are vital for the formation of proteins in the cells.
Sequences are read in the three pairs of codons in the form of triplets to form a form an amino acids sequence.
The amino acid sequence that will be formed from the given sequence AUG-CCC-GGA-UUA-UAG will be:
methionine-proline-glycine-leucine-amber
AUG is the start codon which also codes for the amino acid methionine.CCC codes for the amino acid proline and its one-letter code will be P.GGA is glycine and is abbreviated as G.UUA codes for leucine and is represented by U.UAG is the amber or the stop codon which is responsible for terminating the sequence.Therefore, Met-Pro- Gly- Leu- Amber is the amino acid sequence.

Green plants use energy from the Sun to change carbon dioxide and water into food and oxygen. What clue tells you that this process is a chemical change?
Answer:
Chemical change is a change in which there is rearrangement of atoms and thus new substance is formed. There may or may not be a change in physical state.
Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen. The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar and oxygen gas.

In facilitated diffusion, molecules move down their concentration gradient.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 .
