We are the cause of climate change. It is also caused by biotic factors such as variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions.
Answer:
The statement that best summarizes Gregory Mendel's contribution to science is that Mendel found evidence that there are two factors for each trait.
Explanation:
Mendel is known as the father of genetics. He formulated, through the work he carried out with different varieties of pea, the so-called laws of Mendel that gave rise to genetic inheritance.
By his work he found evidences that there are two factors responsible for carrying the traits from one generation to another. These two forms of traits were dominant (visible in F1 generation) and recessive (visible in F2 generation).
For Example: In peas, the yellow color of the seeds is dominant over the green color, which is recessive.
First question is - Why do we have limestone? Formed from this type of sediment are biological sedimentary rocks. Their biological organ is often revealed in the rock fossils. Some limestones can form by direct precipitation of calcium carbonate from marine or fresh water. (The second question is) - What do iron bands mean? The rocks are "banded" because the iron minerals deposited in alternating bands with silica and sometimes shale. The banding might have resulted from seasonal changes in organism activity steel mill. Most iron ore is used to make steel. Here a steel slab is being cut to length in a steel mill.
Answer:
Neural crest cell movements are inhibited.
Explanation:
Neural crest cells may be defined as the temporary group of cells that are unique for the chordata group. These cells arise from the embryonic ectoderm and give rise to future melanocytes.
Antibodies to fibronectin association is helpful to study the signalling factors. If these anitodies to fibronectin is shown in the embryonical stage. The neural crest migration is inhibited by its exposure to fibronectin and this might hinder the embryonic development.
Thus, the answer is neural crest cell movements are inhibited.
