Surface mining destroys vegetation and affects soil strata. Mining disrupts to topsoil microorganisms. Reclamation operations that dilute topsoil with subsoils can degrade soil.
Surface mining is a type of mining in which the soil and rock covering the mineral deposits are removed. It's the other way to mine underground. The rock on top is left in place, and the needed minerals are taken out through shafts or tunnels.
Surface mining can hurt fish and aquatic resources by causing erosion and sedimentation, drying up wetlands, rerouting and channelizing streams, and putting toxic chemicals into the surface water and aquifers.
This will further disrupt plant life on surface.

Answer:
Surface mining destroys all plant life in the area the mine occupies. Plants living in the area where the surface mine is to be located are removed. ... All three types of mines cause some damage to the environment.

Intro
Done
Answer:
strong, dense outer layer of a bone- compact bone
tissue in the hollow part of the bone- bone marrow
lightweight, inner layer of a bone that
contains many small spaces- spongy bone
Explanation:
Compact bone is also known as cortical bone and is a major property and source of skeletal frames in the body due to its strong, dense outer layer.
Bone marrow is the tissue in the hollow part of the bone. It is important as it helps in the production of blood cells
Spongy bone is also known as cancellous bone. It is the lightweight, inner layer of a bone that contains many small spaces which contains a high proportion of bone marrow.
B: adaption
C: acquired characteristics
D: tendency towards perfection
EXPLANATION:
There are 2 types of nucleic acids: DNA(deoxyribonucleic acid) and RNA(ribonucleic acid).
Living organisms have their genetic material in their DNA. Viruses use RNA as their genetic material but are usually called non-living things( because they can't reproduce without help from a host).
The function of nucleic acids has a progression from DNA to RNA to proteins. This is called the central dogma of molecular biology.
Nucleic acids are formed by a linkage of polynucleotide chains with phosphodiester bonds. These polynucleotide chains are formed from monomers called NUCLEOTIDES.
A nucleotide is made up of 3 parts:
i) a nitrogenous base
ii) a five-carbon sugar
iii) at least one phosphate group.
Answer and Explanation:
DNA as the inheritance materials
Alfred Hershey and Martha Chase state the DNA as genetic material. DNA, or deoxyribonucleic acid, is the natural substance in humans and all other organisms. Every cell in a person's body contains the same DNA. Chromosomes are made up of nucleic acids and proteins and are called hereditary vehicles. ... DNA (deoxyribose nucleic acid) has been found to contain genetic material in all organisms.
RNA as the inheritance materials
• Wandell Stanley, in 1935 proved RNA as genetic material. RNA in humans does not act as genetic material but plays various other roles such as adapters, enzymes, helps in protein synthesis, etc. RNA functions as a messenger for the information to be transferred. The genetic material of organisms and many viruses is DNA. However, some viruses use an alternative type of nucleic acid, ribonucleic acid (RNA), as genetic material. ... RNA has excellent abilities as a genetic molecule; once has to continue the process of hereditary itself.
Nucleic acids
• First, nucleotide are activated, nucleic acid precursors. As such, they are needed for genome replication and transcription of genetic information into RNA. Second, the adenine nucleotide, ATP, is a universal energy currency. Nucleic acids are formed when nucleotide combine through phosphodiester bonds between 5 'and 3' carbon atoms.
Select one of the options below as your answer:
A.Using the same restriction enzyme for cutting the desired gene and the vector and using ligase for pasting the gene into the vector
B.Using two different restriction enzymes for cutting the desired gene and the vector and polymerase for pasting the gene into the vector
C. Using the same ligase for cutting the desired gene and the vector and a restriction
Answer;
A. Using the same restriction enzyme for cutting the desired gene and the vector and using ligase for pasting the gene into the vector.
In genetic engineering the cutting of the desired gene from its genome, then cutting the vector genome and pasting the gene into it is carried out using the same restriction enzyme for cutting the desired gene and the vector and using ligase for pasting the gene into the vector.
Explanation;
Genetic engineering involves adding a new DNA to an organisms with a goal of adding one or more new traits that are not already found in that organism.
It involves ; the isolation of DNA fragments from the donor organism; the insertion of an isolated donor DNA fragment into a vector genome and the growth of recombinant vector in an appropriate host.
Answer:
The correct option is D. Eighteen times more ATP is formed during aerobic respiration than during anaerobic respiration.
Explanation:
Aerobic respiration can be described as the process of respiration taking place in the presence of oxygen. This process makes a lot more energy as compared to anaerobic respiration.
Anaerobic respiration can be described as the process of respiration taking place in the absence of oxygen. This process is one of the earliest reactions that occurred in organisms since the formation of life.
The process of aerobic respiration releases 38 ATP per glucose whereas the process of anaerobic respiration releases 2 ATP molecules per glucose. Hence, the ATP formed during aerobic respiration is approx 18 times more than the anaerobic respiration.
