Explanation:
The Galápagos Islands in the Pacific Ocean have varied habitats
Divergent evolution is occurring on these islands, meaning that the
species that live there
Answer:
had common ancestors but have become increasingly different.
Explanation:
The occurrence of a divergent evolution could be described as the occurrence of a change in the nature or type of a previously existing species. The variation in habitat of galapogos characterized by the existence of divergent evolution establishes the fact that all the species possess a common origin where they all stem from(a common ancestral spiral) however, over time, deviation starts to set in causing variation in the nature and ways of the species. Hence, leading to differences in the these species.

(iii) Write one function of each Microbe used in clean technology:
Microbes
Functions
(a) Geobacter
(b) HCB bacteria
(c) Thiobacilli
(d) Actinomycetes
Answer:
Explanation:
Geobacter is a microbe use in clean technology to oxidize compounds such as metals.
Hydrocarbonoclastic bacteria (HCB) are bacteria that function majorly in the biodegradation of oil hydrocarbons in marine and other environments.
Actinomycetes is a microbe use in the production of antibiotics and recycling of organic matter in the soil.
Thiobacilli are bacteria that have the ability to obtain energy from the oxidation of sulphur and reduced inorganic sulphur bonds. They are Majorly acidophilic or are called acid tolerant bacteria and they are capable of fixing able CO2.
The study of a living being is called biology.
The answer is mentioned below.
Those species which are not able to see with naked eyes are called microorganisms. According to the question, the uses of microbes are as follows:-
Geobacter is a microbe used in clean technology to oxidize compounds such as metals.

Think of an object, person, or place at home that functions similar to the cell membrane.
i think its a plant or dog since both of them also have cells
Because it permits materials to enter and exit a cell, a cell membrane can be compared to a door. A door allows objects to pass through it as it opens and closes.
What is cell membrane made of?With a few rare exceptions, p - series, which are made up of glycerol, a nitrogen base, and two fatty chain, are the primary component of cellular membranes, both cytoplasmic membrane and interior membranes. Therefore, the cell membrane serves two purposes: first, as a barriers keeping the components of the cell inside and undesired materials out, and second, as a gate permitting the passage of vital nutrients through into cell as well as the flow of byproducts out of the cell.
What role does the cell membrane perform?Every cell has a phospholipid bilayer, also called a cell wall, that shields the inside of the body from the outside world. The cell barriers is a lipid bilayer that is porous. The cell regulates the flow of substances from and to the cell.

How can vestigial structures also be considered evidence for evolution?
They provide evidence for evolution because they suggest that an organism changed from using the structure to not using the structure, or using it for a different purpose.
According to the International Union for Conservation of Nature (IUCN) giraffe numbers across the continent of Africa fell 40% between 1985 and 2015. The main threats to the giraffe population include a shrinking habit, conflict, and poaching. Checking the data, we see that while four subspecies have declining populations, four subspecies have growing populations. This is a modern-day example of natural selection at work. What elements of natural selection are at work here? A) Environmental conditions reduce the population numbers; only the fittest subspecies are able to survive. B) Overpopulation exists in a shrinking habitat; some subspecies decline in number; differential reproduction occurs. C) The death rate of some subspecies is elevated due to conflict and poaching; death is random; differential reproduction occurs. D) Genetic variation exists in the giraffe population across Africa; only those animals with a specific gene pool, represented by certain subspecies, can survive. Eliminate
Answer:
According to my calculations 1+1=2 so the answer is A
Explanation:
if 1+1=2 then the answer is A
Environmental conditions reduce population numbers; only the fittest subspecies are able to survive, which is an example of natural selection. Therefore, option A is correct.
What is natural selection?According to Darwin's theory of evolution by natural selection, living creatures that have advantageous qualities tend to generate more children than those that don't. Over time, this causes changes in the characteristics of living things.
Only those individuals will survive that have favorable traits and adapts quickly according to the conditions.
Environmental conditions such as shrinking habits, conflict, and poaching cause a reduction in the giraffe population, only the fittest can survive. It is an example of natural selection. Therefore, option A is correct.

convergent plate boundary: how do the plates and mantle interact?
Answer:
Convergent plates collide causing earthquakes and volcanoes, and creating mountains.
Therefore second answer, The plates move towards each other at these boundaries and the more dense plate will sink under the less dense plate into the mantle where it is destroyed. (This creates a trench.)
Explanation:
In the lithosphere the plates melt when they go down.

how does the earth evlove around the sun while the moon evlolves around the earth with out those two planets colliding
Answer:
This is a rather complicated thing to explain so I'll try my best. To put it in simple term the sun has whats called a SOI (sphere of infleunce) and anything inside of this is effected by the gravity of that planet or sun in this case. The earth is inside of this sphere of influence. The earth has a constant velocity that is making it move away from the sun but since it's in the suns SOI the path in which the earth moves is changed in a way that causes it to spin around the sun. The same thing is happening with the moon. I'm not 100% sure on this but I think the reason the moon does not just fly away towards the sun is because it is closer to earth and is more effected by earths SOI. Hope this cleared things up for you.

If you could develop a scientific cure for something, what would it be and why ?
Answer:
If I could develop a scientific cure for any issue, it would undoubtedly be the cure for the disease of cancer. This is because I believe that cancer is the most cruel and horrible disease that any person can have, since it is ultimately the body itself that acts against the health of the person. Furthermore, in the absence of an effective cure, and given its extremely high incidence rate on the population, an eventual cure for cancer would be the most beneficial scientific and medical discovery in the history of mankind.
