Answer:
The main function of the meristem is to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.
Climate change
Greenhouse effect
Some heat energy from the Earth’s surface escapes into space. If too much heat energy escaped, the planet would be very cold. However some gases in the atmosphere can trap escaping heat energy, causing some of it to pass back to the surface.
These are called greenhouse gases, and they keep our planet warm, which is a good thing. Carbon dioxide is an important greenhouse gas.
Increasing carbon dioxide levels
Humans burn fossil fuels such as oil, coal and natural gas. The energy released is used to power cars and other machines, to generate electricity, and to keep buildings warm. The burning fuel releases waste gases, including carbon dioxide. As the human population increases, more fuel is used, and more carbon dioxide is released.
Global warming
The extra carbon dioxide increases the greenhouse effect. More heat is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. The increase in global temperature this causes is called global warming.
Answer:
A white mouse is purely recessive, and will produce black offspring if the other mouse contributes a black gene.
Explanation:
If Bb then the offspring will be 50% Bb and 50% bb. This is called a test cross, where we use a recessive to determine the genotype of a dominant phenotype.
Answer:
protein - amino acid
Explanation:
Proteins are one of the four major biomolecules in nature. Proteins are polymers of monomeric units called AMINO ACIDS. Amino acids are joined together by a type of covalent bond called PEPTIDE BOND to form proteins. Hence, since proteins are made up of amino acids, the hydrolysis of proteins will result in amino acids.
Hydrolysis is the breaking down of a large polymer into its monomeric unit with the release of water (H2O) molecule as a product. The bonds that forms between the respective amino acids are broken, hence, releasing the amino acids.
