Answer:
The correct option is A.
A. Small test pits can be conducted in an undisturbed part of the surveyed area to find buried artifacts that may not be readily seen on the surface.
Explanation:
This is because archeological survey refers to the study , exploration and digging of sites to obtain archeological remains. The basic sim of this is to get remains that are not visible to man underneath.
usually , the sites are dug out by a shovel so as to determine whether the soil contains any archeological emains that cannot be seen on the surface. This involves the action of excavating the out something or remains especially an archaeological site.
Since ribosomes produce proteins, and the endoplasmic reticulum transports the proteins that the ribosome makes it is advantageous for a protein secreting sell to have ribosomes on the endoplasmic reticulum so that the proteins can be transported more quickly and efficiently
Think of a Tree like a organic solar panel its leaves are cells basically what they do is turn the solar energy into food for themselves if the roots of the tree are too compressed the tree can get root rash and not have enough space to grow. It is important to always put trees in loose soil and let gravity do the work so that it will compact it at the right rate but, earthworms are a great way of fixing root rash because they will dig tunnels all around the roots for them to drink nitrates and nitrites in the soil for nutrients. The leaves turn a yellow color if the roots are that way or if there isn't enough phosphorus in the soil.
Answer: It is as a result of Genetic Mutation.
Explanation:
Mutation and sexual reproduction result in increased genetic variation.
Mutation is the change in genetic content or DNA of an organism. It can be as a result of mutagens or errors during DNA replication. When there is mutation in reproductive cells such as sperm or egg, it can be pass to the next generation. The new traits will become permanent if it is subject to natural selection.
Sexual reproduction involves the transfer of new genes from the parents and to the offsprings which lead to new phenotypes and these can help the organism to adapt to it's environment.
