Answer:
The correct answer is - a lower frequency and a longer wavelength.
Explanation:
According to the question and generally, some snakes have special organs that can sense or detect the Infrared region of the electromagnetic spectrum. However, human eys can not see or detect the infrared region.
Infrared waves have a longer wavelength and lower frequency in comparison of visible light, visible light can be seen by human eyes.
Thus, the correct answer is - a lower frequency and a longer wavelength.
In fact, there are bacteria that grow in all kinds of pH, from the most acidic to the bad alkaline. Depending on the pH at which they live, bacteria can be classified as neutrophil, acidophilic and alkalineophilic.
But in general, when we talk about bacteria that are present in foods, they tend to grow in a pH range between 5 and 9, so they are considered as <u>neutrophil</u>. This can vary by species and other factors such as temperature and available nutrients.
Cells divide for many reasons. For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. Cells also divide so living things can grow. When organisms grow, it isn't because cells are getting larger.
Ans.
Genetic engineering involves manipulation of genetic material organisms to develop organisms with desirable characteristics. Natural selection involves selection of traits that make organisms better adapted to their surrounding environment, without human interference.
Both of the mechanisms involve transmission of genetic information form one generation to another as manipulated genetic material of parent organism is transmitted to next generation.
Both genetic engineering and natural selection select the traits that are most organisms with most beneficial to their environment.
Genetic engineering is faster than the process of natural selection. Natural selection is natural process and it works over generations, while genetic engineering involves desired modification of traits.
Both genetic engineering and natural selection work on all organisms, including humans.
Natural selection involves selection of individuals with beneficial traits for survival, while other individuals with less useful characteristics are wiped out. Therefore, natural selection does not work on entire population.
Thus, the options 1), 3), and 4) are correct.
