Answer:

(4) As time increased, distance remained

the same

Explanation:

The graph shows that the student measures equal distance everyday from the bridge to the rock for 7 days.

Everyday has an equal distance measured by the student all through the week.

Let's say the point on the vertical axis which represents distance measured is about 1.5 meters. It means that, for day 1, he measures 1.5 meters, day 2, he measured 1.5 meters, by day 3 another 1.5 meters. Same he does for 7 days. For the first 3 days, he would have measured 1.5 m × 3 = 4.5 meters.

This means that, as time (days) increased, distance measured each day remains the same.

Answer:

The correct answer is: Your skin is not as permeable as the lining of your digestive system.

Explanation:

Pool water is mostly composed of water with some chlorine in it. This is why it could never be true that pool water is isotonic with a person's internal fluids, where half of the osmotic pressure is given by sodium. For pool water to be isotonic with our internal body fluids, it should be a 0.9% NaCl solution.

The chloride in the pool water has no special properties that make your body not lose electrolytes.

The reason why swimming in a pool doesn't cause sodium imbalances is because the skin is not as permeable as the lining in our digestive system. We don't absorb water or ions through our skin. The only way we can get more water and electrolytes in our bodies is by ingesting them when drinking water or eating food. Then, our digestive system absorbs it, and after that, the kidneys dispose of the excess water or electrolytes.

Explanation:

Water will boil faster when it is heated from the bottom rather than when it is heated from the top.

The boiling of water occurs due to convection currents. Heavier particles moves from upwards and travels downwards and then they are replaced by lighter particles traveling upwards. This is called convection currents.

As such, water will boil faster when it is heated from the bottom rather than when it is heated from the top.

Answer:

Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.

Most galaxies have stars distributed throughout them that are born within dust clouds.

Any large, gaseous celestial body that is self-luminous and emits light as a result of its own internal energy sources is a star.

Stars are created when a very huge cloud of gas and dust in space slowly contracts under the force of gravity.

The presence of gas and dust clouds is relatively widespread, and our knowledge of the Milky Way Galaxy's star-forming regions is extensive.

Stars are born within dust clouds and are dispersed throughout the majority of galaxies. Most galaxies have stars distributed throughout them that are born within dust clouds.

The Orion Nebula is a well-known illustration of a dust cloud of this type.

Deep within these clouds, turbulence creates knots with enough mass for the gas and dust to start collapsing under its own gravitational pull.

Thus, this way, the stars are formed.

When the swimmer starts swimming, it indicates the action-reaction force pair that is present in Option B as the force that is applied by the swimmer on the wall of the swimming pool, and the same force is applied by the wall towards the swimmer.

This action-reaction force is explained by Newton and is also known as Newton's third law, where he explains that every action that is taken shows an equal and opposite force, such as here the swimmer gets the exact same force that he applied on the wall and, as a result, pushes itself to come forward.

Explanation:

The genome can be defined as the genetic material of an organism, which is composed of DNA molecules named chromosomes whose building blocks are four different nucleotides: Adenine, Thymine, Cysotcine and Guanine. The order of these nucleotides specifies the information contained in the chromosomes and, ultimately, in the genome. The genes, which are recognized to be the basic units of inheritance, are genetic sequences composed of ordered nucleotides along the chromosomes. During transcription, a gene encodes different RNA codons (for example, start and stop codons) which are specified by the order of the nucleotide sequence. Finally, the order of the RNA codons will be critical to specify the polypeptide chain during the translation from RNA to protein.

Answer:

The structure of proteins depends upon the sequence of amino acids joined together.  The sequence of amino acids changes the function of proteins.

Large, intricate molecules known as proteins play a variety of vital functions in the body. They are crucial for the structure, operation, and control of the body's tissues and organs and carry out the majority of their job inside cells.

The relationship between a protein's structure and function is direct. The function of a protein is determined by its unique form.

The protein becomes denatured and ceases to function as intended if the three-dimensional structure of the protein is altered as a result of a change in the structure of the amino acids.

Therefore, the order in which amino acids are linked together determines how proteins are structured. The order of amino acids alters how proteins work.
