<span>President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863, whereas Dr. King gave his famous "I Have A Dream" speech on August 28, 1963. Therefore, over 100 years had passed between the two events, and while slavery had been formally abolished for that duration, the Civil Rights movement showed that there was still tremendous work to be done in ensuring equality and fair treatment for African Americans.</span>
Two techniques that are used in order to restore the biodiversity are the sawing of native seeds or planting individual plants, and the reintroduction of animal species native to the ecosystem.
The restoration of the biodiversity is practically trying to get an ecosystem in its initial, pre-destruction condition, and help it function without any human assistance after certain amount of time.
All restorations of the biodiversity are hard and take time, and there's no guarantee that the outcome will be as planned and wanted. Initially, there the sawing of native seeds and planting individual plants, which is crucial as the plants are the basis of the ecosystems. After that animal species are introduced, small and large, herbivores, omnivores, and carnivores. The people initially have to assist the functioning of the ecosystem, but the idea is to make it function properly over time on its own.
Answer:A) proteins are useful as enzymes, hormones etc.
B) the building block of protein are amino acids
Further explanation below
Explanation: A) proteins are polymers formed by several chains of amino acids. They occur in living tissue and form 50 -- 60% of the total dry mass of the living cell. Proteins found in the membrane are used as structural integrity. Some proteins are catalytic in nature and are such are used as enzymes. They also occur as hormones. Proteins help in the transport of substances across the cell membrane, when they are found in the cell membrane.
B) the building block of protein are amino acids. They undergo condensation reaction to form proteins.
The structure of amino acid is in the attached photo.
R = the group that determine the name of the amino acid. It may be a hydrogen atom,an alkyl, an aryl, or carboxyl group.
H2N = the amino group
COOH = the carboxyl group
C = the alpha central carbon to which other groups are attached.
