What are the various ways in which glucose can be oxidised ?
Answer:
1) Aerobic respiration : In this case pyruvate is broken down into water and carbon dioxide along with release of energy. It commonly occurs in mitochondria of cells.
2) Anaerobic respiration in yeast : In yeast cells during fermentation pyruvate is converted into ethanol and C02 in the absence of 02

Human have cut and frayed the woven tapestry of Earth's biodiversity. List and describe three ways.
Answer:
1. Building into the ecosystem.
2. Hunting animals for sport.
3. Increasing carbon emissions.
Explanation:
All of these are bad for Earth's biodiversity. Building into the ecosystem destroys habitats for animals, which causes the population of that species to decline. Hunting animals for sport decreases populations as well, and doesn't keep the environment in check. Increasing carbon emissions heat up the Earth, leading to colder climates warming up. This, in turn, destroys the ecosystem as well.
Anthropogenic activities and continued neglect of the ecosystem has lead to various deleterious effect on biodiversity.
What is biodiversity?It means the presence of several species of animals, microorganisms, and plants in a habitat.
What is the rivet popper hypothesis?According to this theory, the ecosystem is kept together by thousands of species, just as thousands of rivets hold together an airplane.
It may not affect flight safety at first if rivets are removed but over time, the airframe becomes dangerously weak. Similarly, species extinction in the ecosystem impairs the ecosystem's ability to function properly.
What are the three ways in which humans have affected biodiversity?Habitat loss and fragmentation: It destroys the natural habitat and niche of organisms and leads to their decline
overexploitation: It leads to depletion of the natural resources and increases the risk of extinction of endangered species.
Pollution: It destroys the quality of the habitat of organisms and creates a toxic environment which leads to the decline of species.

Earth's early atmosphere had no oxygen. Use your understanding of plant photosynthesis to explain how photosynthetic organisms made the evolution of organisms that use aerobic cellular respiration possible.
Answer:
Before, microorganisms were anaerobes, so they did not need oxygen to carry out photosynthesis, but with the appearance of cyanobacteria, which are blue-green algae, oxygen began to appear in the atmosphere.
These reactions to oxygen photosynthesis, which was what generated a very abrupt change in the ecosystem, since many prokaryotic microorganisms did not support the presence of this gas in the atmosphere and became extinct, others adapted, others developed oxygen photosynthesis such as these algae
These bacteria work with the respiratory chain mechanism and it was they who transmitted this genetics horizontally to other bacteria as an adaptation and evolution mechanism.
Explanation:
The mechanism of transmitting genetic load in a horizontal direction made it not dependent on the following generations, since genetic load is transmitted by routes such as PILI or other means, some of them call this mechanism the lateral transmission method but refer to the same thing.
In simple words, these bacteria imposed the oxygen photosynthesis and transmitted or spread their genetic load based on the encoding of the respiratory chain, so that other bacteria can perform the same metabolic method and adapt to oxygenated media.

Which is the best reason that a geologist might carry a small dropper bottle filled with hydrochloric acid
when doing fieldwork?
to wash rock samples to make them easier to study
to wear away large areas of rock to see what is underneath
to test for the presence of carbonate minerals in a rock
to use as an emergency eyewash in case rock dust gets in the eyes
Answer:
C, to test for the presence of carbonate minerals in a rock
Explanation:
I did this a few weeks ago on Edge. Hydrochloric acid isn't for rock washing, they wouldn't use it to wear away rocks since it'd ruin the sample I think, and you will go blind if you put it in your eyes
Geologist carry dropper bottle filled with hydrochloric acid when doing fieldwork is to test for the presence of carbonate minerals in a rock.
Test for carbonate mineralsHydrochloric acid is used to test for presence of carbon iv oxide in compounds.
When hydrochloric acid reacts with carbonates, it produces effervescent due to the prensence of carbon iv oxides in the compound.
Geologist will use this acid (hydrochloric acid) to check if the rock sample contains carbonate minerals.
Thus, the best reason that a geologist might carry a small dropper bottle filled with hydrochloric acid when doing fieldwork is to test for the presence of carbonate minerals in a rock.

When the total lunar eclipse occurs what are the relative positions of the sun earth and moon
Answer:
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth and moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle.
Explanation:
Answer:
The earth is between the sun and the moon
Explanation:
The Moon is non luminous that is doesn't generate light by itself so it depends on light from the sun so when its path through which it taps light from the sun is totally covered it means the Earth is closer to the moon than the Sun so that the Earth gets all off its light leaving nothing for the Moon and in this case the Moon is thrown to total darkness.

Are the current life forms similar to those of 3.8 billion years ago? How do we know?
Answer:
No, not really. Over time, organisms have grown much more complex. Photosynthesis happened around 3.4 billion years ago and respiration around 2 billion years ago. These all serve as a testimony to the fact that organisms are in fact growing more complex. We have seen photoautotrophs arise, from the simpler chemoautotrophs, and they now in fact dominate the array of producers! Organisms don't only do fermentation now; they can also do anaerobic respiration and aerobic respiration too! Thus, current life forms are a lot more different today than 3.8 billion years ago.
