Answer:
A convergent plate boundary is a boundary at which two plates are moving towards one another, sometimes the two tectonic plates colide, causing the land to lift and form mountains.
Answer:
1) Increased probability of hazardous chemical contamination.
2) Air, water, and soil pollution.
3) Mortality in both terrestrial and aquatic organisms.
4) Development of diseases in humans.
Explanation:
The improper disposal of electronic waste can have detrimental consequences for the environment and, as a result, to all living beings including humans.
If electronic waste is thrown away in an open area, it warms up and releases hazardous chemicals that are detrimental for the health of living beings. This occurs because <u>electronic objects contain toxic chemicals such as lead, mercury, cadmium, amongst others</u>.
These chemicals will eventually enter both soil and water, harming thousands to millions of terrestrial and aquatic organisms. Moreover, these chemicals will enter the food chain and, as humans consume these affected organisms, we are also affected in numerous ways. For example, ingesting these chemicals could cause reproductive issues, damage to both the nervous and digestive systems, the development of cancer, etc.
Answer:
Biology is the study of living things and their processes of life. Both Hooke and Van Leeuwenhoek made major, early contributions to biology.
Robert Hooke
Robert Hooke is best known for the discovery of the cell. Using a microscope, Hooke looked at the makeup of a piece of cork. Through the microscope, he saw box-like structures. What he saw would later be known as cell walls. He discovered that these structures were cells, the building blocks of all life.
His discovery and future research contributed greatly to the cell theory.
Anton van Leeuwenhoek
Leeuwenhoek made his discovery after Hooke, but it was still important. He is best known for the discovery of bacteria. Unlike Hooke, Leeuwenhoek did not study plant cells; instead, he focused on protists (like amoebas) and prokaryotes (like bacteria). For his work with unicellular organisms, he is often called the "Father of Microbiology."
Answer:
Some people may have a higher tendency to develop a certain type of cancer because they carry the gene mutation from their ancestors. For example, in case of women, inheriting a gene mutation in BRCA1 or BRCA2 puts her at a higher risk of developing breast cancer or ovarian cancer.
Environmental agents such as smoking (tobacco), exposure to ultraviolet radiation, certain viruses, to name a few are responsible to the development of cancer in the human body. Overtime, any of these factors can cause irreversible damage to the DNA that could lead to cancer.
Hope that answers the question, have a great day!
The mRNA molecule is the blueprint for protein assembly in the processes described in the central dogma of molecular biology.
The process of translating the information in DNA to proteins happens in three steps.
Firstly, the DNA molecule replicates itself.
After that one DNA strand (DNA is a double-stranded molecule) transcribes itself into one-stranded messenger RNA (mRNA).
The information is held in the sequence of the nucleotides (Adenine, Cytosine, Guanine, Thymine) and it is read in triplets. So each mRNA is made from a sequence of nucleotides copied from the DNA, that is read in triplets.
Each triplet is holding the information about a specific amino-acid carried by transporter RNA (tRNA).
Proteins are made in the ribosomes in the process of translation, where the sequence on the mRNA is being read and translated into a sequence of amino acids.
