Answer:
1. Molecular evidence: similar proteins and genes found in closely related species, even if those genes are not used by an organism.
2. Fossil evidence: organisms changing form over time through the fossil record.
Direct observation. We can directly observe small-scale evolution in organisms
with short lifecycles (e.g., pesticide-resistant insects).
Explanation:
Read the question fully.
Think about a severe weather situation you have experienced near your home or have witnessed on the news.
The question is asking you to tell about any severe weather that you have seen, heard, or you've experienced about and just tell them about it.
Answer:
150 - 300 bp
Explanation:
Micrococcal nuclease, indistinctly from the time of treatment and in average organisms, will realize the cuts on DNA o RNA zones rich in AT or AU. It is not a specific endonuclease.
Even so, the mean size of the expected fragments will have between 150 bp and 300 bp.
It is very important to run your digestion along with a proper label.
Answer: B. Tendons; ligaments
Explanation: Tendons are white, inelastic and tough connective tissue that attach skeletal muscle to bone. Tendons attach muscles to structures such as the eyeball. Fibres in tendons are arranged as compact parallel bundles.
A ligament is a yellow, elastic and strong fibrous connective tissue which attaches bone to bone. Ligaments usually hold bones together and keep them stable. Fibres of the ligament are compactly packed and but they are not arranged in parallel bundles as that of tendons.
