If a person is in front of a smooth surface from which a sound is reflected, the person would hear a sound that seems to come from behind the surface (B). In theory, the sound waves hit the smooth surface and bounce off the surface.  The sound also repeats itself. This is known as an echo. There needs to be a time gap between the sound and the echo otherwise the listener will not hear the echo. It will still be present but form part of the original sound.

Explain the difference between using dna profiles to determine paternity and to match a tissue sample with a suspect
Dmitry [639]
Each person has a unique DNA profile. To determine paternity, only a very limited amount of tissue is used to match the DNA profile of the potential father to that of the child. The genetic test performed to determine whether a tissue sample belongs to a specific suspect needs a more extended tissue sample.

In pigs, curly tails (T) are dominant over straight tails (t). If a pig is heterozygous for a curly tail, what is the pig's geno
n200080 [17]

Answer:

The pig's genotype is Tt

Explanation:

As mentioned in the question that curly hair allele T is dominant over straight tail allele t.

A heterozygous organism is that in which both alleles for a trait are different. Since Curly hair allele T is dominant over straight tail t, it means that the pig with curly tail and heterozygous genotype will definitely have a genotype of Tt.

Hope it helps! :)

Scrat [10]

Answer:

I hope this helps!!!1

Explanation:

Carbon and oxygen are independent of each other but are very closely connected as well as interdependent. The following article will cover information that will help you understand the carbon-oxygen cycle in detail.

Life on planet Earth continues due to the presence of organic as well as inorganic nutrients present in nature. These nutrients need to be continuously recycled. If this doesn’t happen, all the nutritive resources in the world will get extinguished completely. No nutrients means no life on Earmeano, for the life cycle of every living being, unicellular or multicellular organism to sustain, recycling the nutrients is very important. One of the important cycles is the carbon-oxygen cycle.

The Process of Carbon-Oxygen Cycle

There are four steps involved in the completion of this cycle. These methods are discussed below:

Photosynthesis

Plants undergo photosynthesis which helps them produce energy and food for themselves. During this process, plants take in carbon dioxide (CO2) and absorb water (H2O) with the help of their roots. The chlorophyll present in the leaves and the energy from the sun, help convert CO2 and H2O into Oxygen O2, sugar, and water vapor. Oxygen (O2) is released by plants as a by-product of the atmosphere.

Formula for Photosynthesis

CO2 + H2O + Light ———-> (CH2O) + O2

The carbon dioxide from air and water from the soil in presence of light (energy) is taken by the plants and converted into carbohydrates and oxygen as by-products.

Respiration

Just as plants carry out photosynthesis, animals carry out respiration. Respiration occurs when animals take in oxygen from the air along with simple sugars from their food. This helps in the release of carbon dioxide, water, and energy from the animal body. During cellular respiration, animals require O2 while inhalation. When they exhale the waste product of cellular respiration, they release CO2 into the atmosphere again.

Formula for Respiration

(CH2O) + O2 ———-> CO2 + H2O + Energy

The carbohydrates taken from food like plants or carbon-based compounds along with oxygen are converted to carbon dioxide which is released into the air along with water and energy during respiration.

Combustion

It is a process of burning that occurs naturally in nature. For example, volcanic eruptions are natural combustion processes where carbon dioxide is released into the atmosphere due to burning. Nowadays, many environmental pollutants cause an increase in the amount of CO2 in the air. These include cars, factories, burning of woods, coal, nuclear energy, gas, etc. This irresponsible combustion and release of excessive carbon dioxide and other harmful gases in the environment is the major contributing factor to today’s global warming.

Decomposition

After the death of any living organism, i.e., unicellular or multicellular organism, it gets decomposed. This decomposition means insects, fungi, and bacteria (together called decomposers), help in breaking down the cellular components of the dead organism into its basic elements. These elements include water, calcium, nitrogen, carbon, and oxygen. Thus, decomposers help in the release of oxygen and carbon dioxide back into the atmosphere as their metabolic waste products.

The entire cycle can be summarized as, plants taking in carbon dioxide and releasing oxygen during photosynthesis. This oxygen released is taken up by animals who release carbon dioxide after carrying out respiration. Thus, the recycling of carbon and oxygen in the atmosphere will continue as long as respiration and photosynthesis occur. This also proves that to sustain life, plants are very important as they are the major contributors to the amount of oxygen present in the atmosphere. Although both cycles occur independently, they are, in a small way, interconnected to each other.
