Among the options, energy is not recycled in the biosphere. While matter like nitrogen, water, and carbon is cycled within the biosphere, energy flows one-way and is not reused but lost as heat.

In the biosphere, energy is the only component among those listed that is not cycled back and reused. Both matter and energy flow into the biosphere. Matter is cycled within and between ecosystems, such as through the carbon, nitrogen, and water cycles. Energy, however, is not recycled and flows in one direction. Sunlight is the initial source of energy for almost all life on Earth. It is converted to chemical energy by photosynthetic organisms and then passed on to consumers through food chains. This energy is not recycled but lost as heat as it passes through the food chain.

The process that leads to deforestation and increased erosion is mining. Find more explanation on mining below.

Mining is the process or activity of removing solid valuables from the earth.

During the mining process, solid parts of the Earth crust are removed so as to reach the minerals beneath it.

This leads to the deforestation i.e. removal of trees without replacement and increased erosion due to exposure to agents of erosion.

Answer:

denamrk is a very populosus country

Answer:D lead

Explanation:

Based on the graph, it appears that the air quality standards have had the greatest impact on lead.

National air quality refers to the level of pollution in the air across an entire nation.

The graph shows a significant decrease in lead concentrations since 1990 when the EPA began regulating lead emissions. The other pollutants, while still showing improvement, do not have as drastic of a decrease as lead.

The graph provided shows the change in concentrations of common air pollutants over time. The pollutant that stands out the most in the graph is PM (particulate matter), as it shows a significant decrease in concentrations over time.

This suggests that the air quality standards set by the EPA have had a positive impact on reducing PM concentrations in the air. Ozone, NO (nitrogen oxide), and lead also show some level of decrease in concentrations over time, but the decrease is not as significant as that seen with PM.

Answer:

True

Explanation:

Yes this is true due to advancements in genetic engineering.

A bacterium was transformed by scientists into a plant with the main purpose of the production of biofuel. The microorganism was expelled of its fatty acid but this synthetic route of extraction and purification is however very expensive.

The production of this fuel has several problems such as insufficient rates to meet the production rates of demand for biofuel while being competitive with oil and other forms of biofuel.

Answer:

C. Application of toxic fertilizers to crops

Explanation:

Water pollution is defined as the contamination of water due to several human activities. Several causes of water pollution include use of fertlizers, construction of turbine, industrial waste, and sewage dumping.

Use of toxic fertizers directly affects the loss of water quality as fertilizers and pesticides are made up of chemicals such as phosphate and ammonia. The fertilizers and pesticides precipitate through the soil and mix with ground water that directly affect the quality of water. Residues of chemicals mix with river water due to flooding, excess irrigation, heavy rainfall and enter in the food chain. These chemicals are then have lethal effect in living organisms.

Hence, the correct answer is C.

Answer:

The correct answer is option B. "complete dominance".

Explanation:

Widow's peak is a trait characterized by the growth of a hairline in the center of the forehead. By looking at the pedigree we can conclude that widow's peak has no sex-linked inheritance because there is father-to-son transmission. There is no codominance or multiple alleles inheritance neither, because there is no slight differences in the trait (people either have or not have widow's peak). We can conclude that widow's peak have a complete dominance inheritance, because in the case where both parents have widow's peak they have a female daughter with no widow's peak. This means that both parents were  heterozygous of the widow's peak allele, and since both expressed the trait we can conclude that it is completely dominant.

Answer: C Sweet Fruit

The plant adaptations allow plants to use animals to transport their seeds to new locations is sweet fruit. The correct option is C.

Adaptation is a type of changes or acceptance of the body according to the environment and surroundings for better and easy survival. Adaptation can be for short time or long time.

Animals are important factor for the pollination of flowers and transportation of seeds to new places and in increasing the population of the vegetation.

Animals most probably eats sweet fruits, and when they eat these fruits their seeds are to fall into ground and grow new saplings. They take fruits with them to different places, which also propagate the plat to different places.

Thus, the correct option is C. sweet fruit.

In peptide bond formation, the amino group of one amino acid reacts with the carboxyl group of another, creating an amide bond. The polypeptide chain has a directional structure with a free amino group at the N terminal and a free carboxyl group at the C terminal, crucial for protein function.

Amino acids are the building blocks of peptides and proteins, linked together by peptide bonds. The groups involved in forming a peptide bond are the amino group (-NH2) from one amino acid and the carboxyl group (-COOH) from another amino acid. During the formation of a peptide bond, these groups combine in a dehydration synthesis reaction, resulting in the release of a molecule of water and the creation of an amide bond between the two amino acids.

The resulting polypeptide chain has a free amino group at the N terminal and a free carboxyl group at the C terminal. This directional structure is important as the sequence of amino acids, which determines the protein's properties, is read from the N terminal to the C terminal. The unique sequence of amino acids is key to the protein's structure and function after it goes through post-translational modifications to become fully functional.

Answer:

The square of the ratio of the periods equals the cube of the ratio of radii.

Explanation:

German astronomer Johannes Kepler who lived from 1571-1630, gave the three descriptive laws called Kepler's law. He derived this law after he had study and make observations of planetary motion done by Tycho Brahe.

The Kepler's third laws state that the square ratios of the period equals the cube ratio of the distance or radii.

From Kepler's third law, the square of the ratio of the periods equals the cube of the ratio of the radii.

Kepler's third law states that the ratio of the square of an object's orbital period with the cube of the semi-major axis of its orbit is the same for all objects orbiting the same primary.

The law is simplified using mathematical formula as follows;

T² ∝ R³

[tex](\frac{T_2}{T_1})^2 = (\frac{R_2}{R_1} )^3[/tex]

where;

Thus, we can conclude that from the Kepler's third law, the square of the ratio of the periods equals the cube of the ratio of the radii.

Answer:

true

Explanation:

any force can be added to make a stationary object move. but if it was balanced then it would just stay in position

if there is 100N of force going towards the object, and you are pushing the object with 100N force. It  will not move.

Final answer:

The statement that an unbalanced force must act upon a stationary object to set it into motion is true according to Newton's first law of motion. An object at rest remains at rest, while an object in motion maintains its velocity unless acted upon by an unbalanced force.

Explanation:

The statement that an unbalanced force must act upon a stationary object to set it into motion is True. According to Newton's first law of motion, also known as the law of inertia, an object will not change its state of motion (i.e., it will not accelerate) unless an unbalanced force acts upon it. This means that if an object is at rest, it will stay at rest until a force that is greater than the sum of all opposing forces is applied to it. Contrary to misconceptions, a force can do work even if an object doesn't move, for instance if you're pushing against a wall with a force, work is being done on a molecular level, although there's no macroscopic movement.

When two unequal forces act on an object, the object will move in the direction of the net or resultant force, which is the vector sum of all the forces acting upon it. If this net force is zero, the object will remain stationary or continue to move at a constant velocity. This is a fundamental concept in classical mechanics.
