Answer:

Natural Selection (Answer Below)

Explanation:

Natural Selection is the selection of a more beneficial trait. For example, if trees get covered in soot all the white beetles and butterflys are going to stand out like a sore thumb, but the beetles and butterflies that adapted and evolved now have better traits that help them hide predators. The predators have a harder time finding the now black colored butterflies and beetles due to the black soot meaning the beetles and butterflies will have a higher survivability

The correct statements for amino acids but not for sugars are :

C. typically contain nitrogen

E can bond together to form proteins

Explanation:

Both Sugars and amino acids always contain carbon molecules and both macromolecules can provide energy so are the source of the energy. Sugar molecule more specifically glucose molecule enters glycolysis during the cellular respiration process.

Amino acids always contain the nitrogen molecule in the structure along with carbon, oxygen, and hydrogen, there is a side chain present. Amino acids are the building blocks of the protein, peptide bonds are formed by amino acids together to make a poly peptide chain of a protein molecule.

Answer:

The speed of the frog is 1m per second the velocity is he can turn and jump in a different direction in 1 second the distance is 1m and there is no displacement.

( this was not my answer but it’s right. I saw it in the comments)

Explanation:

The speed of the frog is understood to be 1m/sec.and the velocity is that through which a frog can turn and jump in a different direction in 1 sec the distance is 1 m. This returning back to the original position represents no displacement.

Displacement may be defined as the rate of change in the position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position.

Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time. The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s).

Speed may be defined as the rate of change of position of an object in any direction. It is measured as the ratio of distance to the time in which the distance was covered. It is a scalar quantity as it has only direction and no magnitude.

Answer:

Explanation:

The solid waste that is stored in the colon until it is expelled from the body is a product of the digestive system, which is responsible for the breakdown and absorption of nutrients from food. Therefore, option (B) is correct.

The digestive system is a group of organs and structures in the body responsible for the breakdown of food into nutrients that can be absorbed and used by the body. The system includes the mouth, esophagus, stomach, small and large intestines, liver, pancreas, and anus.

The excretory system is responsible for removing waste products, including solid waste, from the body. The colon, which is part of the large intestine, is where water is absorbed from undigested food and the remaining waste is stored until it is eliminated from the body.

The circulatory system is responsible for transporting oxygen and nutrients to cells and removing waste products, but it is not directly involved in the storage or elimination of solid waste.

The respiratory system is responsible for gas exchange and the elimination of carbon dioxide, but it is also not directly involved in the elimination of solid waste. The muscular system is involved in the movement of the body, but it is not directly involved in the storage or elimination of solid waste either.

Explanation:

Characteristics of the layer that make Concorde to travel is The temperature increases with weight.

Concorde fly so high because the higher it flew, the thinner the air was that it encountered. This consequently led to less drag and fuel burn.

Able to cruise at a near-stratospheric altitude of 60,000 feet at 1350 miles per hour, the plane cut travel times on its routes in half. But speed and altitude were not the only factors that made Concorde so remarkable.

Use Darwin’s finches as example they were separated and speciation occurred in the changed beaks

In which situation is speciation MOST likely to occur is few members of the population are isolated from the others.

The speciation process usually occurs due to adverse conditions imposed by the environment. Briefly, two causes are attributed for the process to occur: Geographical Isolation: When lineages of a species separate from the rest of the species for environmental reasons.

In this case, a species no longer identifies with it and thus it isolates itself from its environment.

The light energy that originates from the sun provides the energy to grow oranges, which contain macromolecules.

Please do not be upset if this is wrong.

The ultimate source of energy received by digesting orange is the light energy that originates from the sun provides the energy to grow the oranges, which contain macromolecules. Thus, the correct option is C.

The ultimate source of energy of the solar system is the Sun. It is the primary source of energy for the Earth. The sun is called the ultimate source of energy because it is the source of almost all energies of the earth.

With the help of solar energy, all the green plants (producers) produce food by the process of photosynthesis. In turn, animals eat plants and use the chemical energy for all the activities such as cellular activities.

Answer:

Introns

Explanation:

The coding region of the gene is the part of the gene that is transcribed. However, not all of the gene makes the final mRNA. There are sequences called exons and introns in the coding region of the gene.

The pre-mRNA contains transcribed sequences of both the introns and exons. However, the introns are removed from the final mRNA by splicing. The final mRNA that is translated to the protein only contains exons. An illustration is attached to illustrate this.

Answer: C. Chemical reaction absorb or release thermal (and sometimes other) energy

Explanation:

Chemical reactions can result in products with more or less chemical energy than the precursors. When products have less chemical energy, the excess is converted to heat (exothermic reaction)

When the products have more chemical energy, heat must be added to make up the difference (Endothermic reaction)

Fireworks are examples of exothermic reactions where the excess is released as thermal, mechanical, and radiant energy. A lit match releases thermal and radiant energy.

Respiration is also an exothermic reaction

C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy

Respiration is the reverse of photosynthesis, an endothermic process. The overall photosynthetic reaction is 6CO2 + 6H2O + energy  —> 6C6H12O6 + 6O2

In this case radiant energy drives the reaction.

The reaction 2H2O —> 2H2 + O2 is an endothermic reaction driven by electrical energy.

Many reactions are reversible and if one is endothermic, the reverse is exothermic e.g. 2H2 + O2 —> 2H2O +energy is the reverse of electrolysis of water, or respiration vs photosynthesis.
