1. Energy from the sun is transferred to earth's surface. Some of that energy is then transferred to the air above the surface.
2. The closer a location is to the equator the more energy it receives from the sun. Therefore a location's air temperature is affected by its distance from the equator.
3. An effect my have more than one cause. These may be linked into a chain of effects and causes.
Answer:
Fibrous
Explanation:
Proteins are assembled according to their functions. Fibrous proteins usually provide protection and support to cells. They are made up of polypeptides that have elongated shape and assembles in large cables or threads. These proteins are differentiated from globular proteins by their globular form and repeated units of amino acids.
For example the fibrous proteins involved in horns, hair and nails is alpha-keratin. Elastin found in skin and ligament is also a fibrous protein. Collagen includes collagen fibrils that have tensile strength of steel is also a fibrous protein found in cartilages and bones.
Answer:
The correct answer will be option-D
Explanation:
The aerotaxis movement experiment performed by the Theodor W. Engelmann played an important role in understanding the photosynthesis.
The experiment was performed on the <em>Spirogyra </em>filamentous algae which were exposed to a different wavelength of light.
The other aerobic bacteria present in the test tubes started moving and accumulated near the two regions of the <em>Spirogyra</em> where they were exposed to the blue and red light of the VIBGYOR.
The region receiving red and blue light produced more oxygen through photosynthesis which indicated that these two wavelengths of the light are more active for photosynthesis than any other wavelengths.
Thus, option-D is the correct answer.
Answer:
Details about DNA are given in the explanation section. Hope it will be helpful for you.
Explanation:
DNA, or deoxyribonucleic acid, is the hereditary element in humans and almost all other organisms. Nearly every cell in a person’s body has the same type of DNA. Most DNA is found in the cell nucleus (nuclear DNA), but a small quantity of DNA can also be found in the mitochondria (mitochondrial DNA or mtDNA).
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same type in all people.
DNA bases pair up with each other, A with T and C with G, to form units that are called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. A base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.
A valuable feature of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases.
Answer:
Population A: K, D, F, H, I
Population B: L, E
Population C: G, J
Explanation:
Biologists studying disease susceptibility in mice used genetic techniques to look for gene flow in 12 wild populations of mice. The populations (designated A through L) were located along a 210-km transect line.
