Nastasia [14]3 years ago

The origin of life depends on a wide number of issues, all related to the existence of planetary and stellar bodies, chemical elements and the favorability of conditions for life created with such elements and under conditions not overly chaotic or disruptive and with energy sources that are balanced and moderate. As a result, the conditions for life can only result after the conditions of the universe are settled. It took the universe approximately 9.3 billion years to form galaxies and stars and planets that satisfy the demands of life on a fundamental level. It then took 4.5 billion years to condition the Earth through inorganic and organism progression to achieve the pinnacle of creation, which is humans.

Answer:

Explanation:

When earth came into existence, it was very hot. The earth has no atmosphere. The environment of the earth was not suitable for the lives. There was no water, oxygen, which was needed for life. The earth was filled with ammonia, carbon dioxide, water vapor, and methane gas. Gradually the water vapor splits and forms oxygen and hydrogen. The oxygen atoms again combine with oxygen atoms from the ozone layer and the earth's atmosphere. The water vapors start cooling and start raining.  Also, the splitting oxygen atoms combine with methane and ammonia and produce water. The raining in the earth had been going on till the earth got cool down. Thus the larger holes of the earth were filled with water and formed the ocean. After the formation of the ocean, life came to existence. The first organism was a unicellular organism lived in the ocean. By the process of evolution, many complex organisms were crowded on the earth. Thus the earth atmosphere became suitable for life.

Water harvesting, the collection of rainfall and run off for future use, has been practiced for thousands of years; but in some
lina2011 [118]

Rainwater is normally free from dangerous substances, which makes it perfect for irrigation schemes. Added significant benefit is that it decreases the requirement for fresh water. It is important particularly in regions with low water levels.

Another benefit might water harvesting have in these areas with land erosion due to runoff are as follows;

Reduces Water Shortages

In temperate areas, the strain on public water supply can become hard, even in advanced countries. Rainwater decreases the uncertainty of water shortages. Using rainwater for non-essential actions such as spraying the lawn means less pressure on the supply of safe drinking water.

Replenishes Groundwater

Extensive rainwater harvesting projects with the water collected into storage containers or tanks are important to assure a sustainable groundwater level.

Reduces soil erosion

Heavy rainfall generates erosion because some of the soil is transferred along with the passage of water. Soil erosion exhausts agricultural land of topsoil and nutrients, provides to sediment build up in waterways and, in advanced cases, can turn land inadequate for agriculture. Harvesting rain checks a great chance of soil erosion before it can originate.

Describe two examples of steroids and their physiological function.
Musya8 [376]
Testosterone is a steroid. Its physiological functions are:

Determines the the gender of a developing embryo

Development of reproductive organs and the prostrate gland in males

Responsible for secondary sexual characteristics in males such as deeper pitch, increased muscle bulk, hair on the upper lip

Regulates normal sperm development

Another is cholesterol. Physiological functions are:

Helps maintain the structure of cells and vessels improving overall health and function in the body.

Percursor to important sex hormones such as testosterone and estrogen.

Used as an insulator around nerves and is absolutely essential for brain function.

Precursor to Vitamin D, which supports a healthy immune and nervous system

Proteins act as what in cells to control reactions
Damm [24]

The answer is; catalyst

These proteins are called enzymes. They work by lowering the activation energy of reactants and hence speed up the biochemical reaction. They are not affected in the process hence one enzyme molecule can catalyze many reactions. An example of such an enzyme is carbonic anhydrase that enables carbon dioxide to dissolve in blood plasma as carbonic acid.

In the cell, energy that drives endergonic reactions is often obtained from
IRISSAK [1]

Answer: B) energy released from exergonic reactions.  

Explanation:

Cell metabolism is the set of reactions that occur in the cellular environment to synthesize or degrade biomolecules to produce energy. Synthesis metabolism of biomolecules is known as anabolic (anabolism) and catabolic degradation (catabolism).

Endergonic reaction (product has more energy than reagents) and requires energy to occur. Anabolism occurs when the cell has sufficient energy or substrate. Catabolism, in turn, occurs in situations in which the body needs energy, such as between meals and fasting.

The reactions of anabolism and catabolism are opposite but occur in an articulated manner, allowing the maximization of available energy. Thus, while catabolism occurs spontaneously, an exergonic reaction with ATP production, anabolism is non-spontaneous, or endergonic, requiring energy to occur. In other words energy that drives endergonic reactions is often obtained from B) energy released from exergonic reactions.
