Answer:
The oceans are present on the 70 percent of the world but only 5 percent of the total oceans are explored yet.
There are many reasons of this problem but the most important is the hydrostatic pressure.
Hydrostatic pressure can be described as the pressure or weight exerted by the water on the object.
With every increase in 10 meters the pressure increase by 6.47kg (14.27lbs) each square inch of surface.
Due to extreme pressure, oxygen level in the cells of body fluctuates and person becomes unstable and can become unconscious.
Answer:
The intracellular is where enzymes need to perform optimally or near optimum.
Explanation:
The Km is the concentration of molecules where an enzyme performs at half of its maximum velocity (Vmax). Therefore, when molecules are near Km the enzyme is able to hydrolyze molecules nearer its Vmax.
Answer:
It's 3!
Explanation:
There must be genetic differences so the best fitted organisms will survive. If they were all the same then no one would be best fitted and Natural Selection wouldn't be able to occur
It's not 1 because a food shortage isn't required, there's always competition for food sources
It's not 2 because there doesn't need to be a change in the environment for natural selection, just for evolution.
And it can't be 4 if 1 and 2 are wrong!
Hope this helped!
Three of the major characteristics used to classify organisms are cell structure, mode of nutrition and cellularity. These characteristics help scientists determine how organisms are similar to each other as well as how they are different from each other.
Classifying an organism according to its cell structure means determining if it is a prokaryote or eukaryote and then determining if the organism has a cell wall or other organelles, according to Dave Krupp of the University of Hawaii .
Mode of nutrition refers to how an organism gets its food. Organisms can be classified as autotrophs or heterotrophs. Autotrophs make their own food, while heterotrophs must eat other organisms to survive. If an organism is an autotroph, it can also be classified as a photoautotroph or a chemoautotroph. Stephen T. Abedon of Ohio State explains that photoautotrophs produce their own food using energy from sunlight. Chemoautotrophs produce food using the energy from electron-donating compounds.
Cellularity refers to how many cells an organism has and how those cells are arranged. Some organisms are single-celled, while others are multicellular. Advanced organisms have cells organized into tissues.
Answer:
B. 18
Explanation:
An atom, which is the smallest indivisible particle of matter, further contains certain particles called SUB-ATOMIC PARTICLES namely: proton, neutron and electron. In a neutral/uncharged atom, the number of proton is equal to the number of electrons. The number of protons in an atom represent its ATOMIC NUMBER.
However, the sum of the proton number and neutron number gives the MASS NUMBER i.e. mass no. = proton no. + electron no.
Hence, according to this question which states that an atom has an atomic number of 17 and a mass number of 35. The neutron no. can be calculated as follows:
Neutron no. = mass no. - proton no.
Neutron no. = 35 - 17
Neutron no. = 18
