Most likely an altimeter,
microscopes can be too heavy to carry outside,
x-ray diffraction is used to determine the molecular structure of a crystal so that is not likely to be helpful,
but an altimeter determines the altitude of an object on a fixed level, so that can be useful during a field investigation
hydrometers-measure gravity of liquids, probably not useful for a field investigation
Answer:
No. Gender traits in humans are largely determined by biophysical processes.
Explanation:
There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary. But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to. This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development.
Answer:
The correct answer is option A
A. A marine body fish
Explanation: this is because they need to retain water. The piscine kidney cannot afford to produce a urine of higher concentration than the fluids in the body so production is kept at minimum.
Answer:
The correct answer is option b, 0.3m/s
Step by Step solution:
The relation between speed, wavelength and frequency of a wave is given by the following equation:
Speed = Wavelength x Frequency
Substituting the values in above equation we get –
= 3 x 0.1
= 0.3 m/s
Answer:
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.
