Corals obtain energy from tiny photosynthetic algae, called zooxanthellae, which live inside the coral's tissue. How do you thin

Step2247 [10]

Photosynthesis is a process that uses the soliare to produce chemical energy (glucose). This means that the algae living in the water require a supply of solar light, and for that it would be necessary that the water is clear so that the solar rays can pass and reach the algae.

In the case where these corals and algae live in a cloudy or muddy water, the sun's rays do not pass very well, and therefore the photosynthesis of these algae is altered.

hammer [34]

In the context of scientific approach, the role of data is central as well as fundamental when scientists search for observations which would either verify or reject their ideas regarding the world.

The scientific approach follows a systematic order in which theories or hypotheses are tested through experiments and observations are recorded. These observations are in the form of raw data which are then analyzed by scientists.

Analysis of the data leads to the generation of information which can be utilized suitably to develop an insight about the subject of interest. This information is helpful in determining whether an idea or theory is substantial or not.

Explain at least three ways in which a mutation in an individual's DNA could occur, and describe at least 2 effects a mutation c

krek1111 [17]

Answer:

Mutations can occur from the following ways:

1. Errors that occur in DNA replication during cell division

2. Exposure to high-energy electromagnetic radiation

3. Exposure to chemicals mutagens

Effects of mutation include:

1. Genetic disorders

2. Cancers

Explanation:

A mutation is a change or alteration that occurs in the DNA sequence of a cell of an organism. These mutations can be passed on to offsprings of that organism. Mutations can occur from the following ways:

1. Errors that occur in DNA replication during cell division: during the process of cell division, the DNA in cell are copied many times. Some errors result when copying DNA, most of which are corrected during proofreading. However, some changes in the DNA sequence may not be corrected, thus resulting in a mutation.

2. Exposure to high-energy electromagnetic radiation: some types of electromagnetic radiation are ionizing, such as UV rays and X-rays. Prolonged exposure to these ionizing radiation may result in permanent damage to parts of the DNA, thereby resulting in a mutation.

3. Exposure to chemicals mutagens: mutagens are substances which are able to cause mutations. Some common chemical mutagens are alkylating agents such as ethylmethane sulfonate and N-methyl-N-nitrosourea.

Effects of mutation include:

1. Genetic disorders: in genetic disorders, certain normal functioning of the body processes are impaired. For example, hemophilia whereby blood lacks the ability to clot normally resulting in excessive bleeding.

2. Cancers: cancers occur when the cell of the body differentiate and grow abnormally. Various types of cancers include breast cancer, prostrate cancer, blood cancer etc.
