Which one is the true answer

Explanation:

A would be the correct answer

Answer:

second one is the best which describes roots

The main function of root hairs is to absorb water and minerals from the soil.

The function of root hairs is to absorb water and nutrients from the soil and it sent to the upper parts of the plant. In roots, most water absorption happens through the root hairs.

So we can conclude that the main function of root hairs is to absorb water and minerals from the soil.

In this exercise we have to use the knowledge of climate changes that demonstrate the increase in the sea level, in this way we have that:

The submerging of low islands and coastlines or letter B.

The rise in sea level caused by global warming could reach 2 meters in height by the end of the 21st century. This rise in the oceans would leave thousands of kilometers of coastline at the mercy of flooding, jeopardizing the safety of 745 million people worldwide.

The recent rise in sea level is a result of global warming through two main processes: expansion of sea water due to warming of the oceans, triggering its thermal expansion, and the melting of ice masses.

Answer:

Yes

Explanation:

The enzyme substrate complex may be defined as the enzyme when interacting with the substrate at an active site and it produces a new product in the process. It is temporary molecule formed when the substrate comes in contact with the enzyme.

An enzyme is the molecule of a protein which acts like an organic catalyst and a substrate is a the molecule which interacts with the specific enzyme to form a product.

Therefore, the enzyme substrate complex concentration is the product of the substrate concentration as well as the enzyme concentration.

Answer:

The third statement is not true.

Explanation:

Cells release small amount of chemical energy from glucose.

The correct answer is: "Cells release large amounts of energy in the form of heat."

Cells release energy by the process of cellular respiration.

A cell is the smallest unit of a living organism which can have independent existence.

Cells obtain energy by the process of cellular respiration. During cellular respiration, during cellular respiration, the energy stored in glucose is transferred to ATP.

The process of cellular respiration releases energy in cells in small controlled amounts.

Answer:

You can react it with water to produce energy-rich hydrogen gas, or with hydrogen to produce useful chemicals, such as hydrocarbons or alcohols. If there were a sustainable, cost-efficient route to transform CO2 to CO, it would benefit society greatly.

Complete question: Sickle-shaped red blood cells result from a mutation in the gene that codes for hemoglobin. This mutation results in sickle-cell anemia. A partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia are shown below (the diagram is in the attached file)

What type of mutation is depicted in this sequence?

Answer:

The type of mutation is known as SUBSTITUTION.

Explanation:

Sickle cell anaemia is an inherited disease caused by abnormal shape of the red blood cell. This abnormal red blood cell contains less haemoglobin and cannot transport oxygen efficiently round the body. Sickle-shaped (abnormal) red blood cells result from a MUTATION in the gene that codes for hemoglobin.

Mutation is the random changes in DNA that alters genetic information and so introduce new characteristics. The different categories of mutations include:

--> Chromosomal mutation and

--> Point mutation.

SUBSTITUTION is a type of point mutation in which one base is incorrectly added during replication and replaces the pair in the corresponding position on the complementary strand. From the diagram, a partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia, shows a substitution of an A for the middle T. This leads to GUA in the messenger RNA, which specifies the amino acid valine. The substitution of valine for glutamic acid at this particular position alters the chemistry of the hemoglobin such that it sticks together if it is not binding oxygen, creating sickling of the red blood cells.

Answer:

C, 22 pairs

Explanation:

Humans have 22 pairs of autosomes

Answer:

The youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials. The oldest is 12(upper one) because decomposed material are found at the top most of organisms. They are highly decomposed material. They don't decompose easily.

Decomposition of organic matter is a complex process that involves the breakdown of complex molecules into simpler ones by the action of microorganisms. In the case of the layers mentioned, the higher layers are the oldest because the decomposed material is found at the top of the layer, and it takes a long time for the organic matter to decompose into soil.

The highly decomposed material in these layers is called humus. Humus is a dark brown or black organic substance that is a result of the decomposition of plant and animal matter. It is an essential component of healthy soil as it provides nutrients to plants and helps retain moisture in the soil.

Humus does not decompose easily because it is a stable form of organic matter. It is made up of complex molecules that are resistant to further decomposition. This makes it an important component of soil fertility as it can remain in the soil for hundreds of years, providing a steady source of nutrients for plants.

Overall, the highly decomposed material found in these layers is an important indicator of the age and health of the soil. Understanding the decomposition process and the factors that affect it can help us better manage our soil resources for agriculture, forestry, and other uses.

Explanation:

Answer:

every muscle cell of the motor unit is stimulated to contract.

Explanation:

Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.

In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.

Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.

For example, opening the door of a microwave oven as soon as its timer beeps.

Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.

Action potentials generates the nerve impulse in a motor neuron.

When an action potential is generated within a motor neuron, every muscle cell of the motor unit is stimulated to contract.
