Answer: Light can influence gene expression at caterpillar stage which can further influence butterfly wing development. This hypothesis was proved by Thomas Hunt Morgan in 1917 a biologist who conducted studies on butterflies from two different species : <u>Vanessa</u> <u>urtica </u> and <u>Vanessa</u> <u>io </u> caterpillars under red, green, or blue light whereas other caterpillars were kept in the dark. He found that there were differences in color and size of wings of butterflies exposed to different light conditions. Exposure to red light resulted in bright colored wings while exposure to green light resulted in dusky wings. Blue light and dark light resulted in paler colored wings. Also, V. urtica caterpillars reared under blue light and V.io butterflies reared in dark wings developed were larger in size.
Therefore light which is an external environmental factor can influence gene expression which can further influence phenotype of the organism.
Hence in the given situation butterfly would show differences in their wing color if in the caterpillar stage they were grown in dark or bright white light.
You would need a picture of the graph to see the velocity
Answer:
RAT malware
Explanation:
Malware is a collection of malicious software designed to intentionally harm a computer. There are different types of malware which include computer Viruses, worms and Trojan horses.
A Remote Access Trojan is an example of a malicious software that allows unrestricted and unauthorized access to a victims computer due to creation of a backdoor for administrative control.
Therefore, the free weather program had also installed a RAT to the users computer that allowed the threat actor to have unrestricted access to the computer

Answer:
Oxidize organic compounds AND use organic compounds as terminal electron acceptors. (Ans. E)
Explanation:
Anaerobes are the organism that does not require oxygen for their growth. The anaerobes are subdivided into three main classes:
1) Obligate anaerobes: These organisms use anaerobic metabolism to grow and killed in the presence of oxygen. Obligate anaerobe examples are Clostridium and Propionibacterium.
2) Facultative anaerobes: These organisms prefer to grow using aerobic metabolism processes and switch to anaerobic metabolism in the absence of oxygen. An example of facultative anaerobic bacteria is Lactobacillus.
3) Aerotolerent anaerobes: These organisms use anaerobic metabolism to grow and can survive in both conditions (oxygen and oxygen-free environment).
Anaerobic bacteria, oxidize organic compounds rather than oxygen & use organic compounds as terminal electron acceptors. Anaerobic bacteria release hydrogen sulfide gas as they decompose algae in the water. This process is also known as Anaerobic Respiration, in which formation of ATP without oxygen.
