Answer:
How long is the G2 phase = 6hours
Explanation:
Cell cycle undergoes various stages during mitotic cell division.
Normally cells are arrested in the resting phase G0 but as the cell division starts it undergoes G1 the growth phase then it undergoes S phase called the Synthesis phase in which the DNA synthesis occurs. Then it undergoes G2 Phase and is the shortest phase while G1 is the longest phase of the cycle. G2 normally lasts for 3-4 hours so here it may take 2.775 hours as due to presence of Thymidine the synthesis of DNA occur at high level so it contains higher levels of cellular DNA than in the G1 . so it will take 6hours G2 phase to occur.
Answer:
See the answer below
Explanation:
First, the image tells that chromosomes are made up of genes or that genes are located on chromosomes. It further showed that genes are translated as proteins in the cell and this protein respectively control the expression of traits.
Secondly, it also showed that during sexual reproduction, the offspring produced usually have the same proteins as the parent and therefore have exactly the same traits as the parent. Only one parent is needed for asexual reproduction.
<u>However, two parents are needed for sexual reproduction where each parent donate chromosomes containing gene to the genome of their offpsring. The mixture of genes ensures that the offspring look different from the parent.</u>
<em>The image further showed that asexual reproduction does not lead to any variation while sexual reproduction leads to variation of the offpsring from their parents.</em>
These changes can be natural, such as through variations in the solar cycle.

With this information we can conclude that these changes may be natural, such as through variations in the solar cycle. But since 1800, human activities have been the main driver of climate change, mainly due to the burning of fossil fuels like coal, oil and gas.

Answer:
A set of paradigms or views shaped by one's background, culture and education which determine the way an individual or a group evaluate and find solutions to the existing environmental problems.
Explanation:
Environmental value system (EVS) is a view of a subject that transforms the way an individuals or the society thinks, view and evaluate environmental issues.
Their ideas and views is influenced by cultural, economic and socio-political background.
Factors such as education, media and religious doctrines are inputs in ESV that enhance perception.
Information are processed and changes perceptions of the environment by an individual and also changes decisions.
