The discovery of microbes as discrete entities sharing many of the characteristics of larger plants and animals was made possible by the development of microscope.
What is a Microscope?This is referred to an instrument which is commonly used in the laboratory to examine objects that are too small to be seen by the na-ked eyes. It does this by the process of enlargement of the objects and it brought about new discoveries about plants and animals.
It made the organelles present in cells to be more visible and their similarities and differences were noted which were also compared to that of microbes so as to find out their common ancestry.
This is therefore the reason why discovery of microbes as discrete entities sharing many of the characteristics of larger plants and animals was made possible by the instrument.

what would be the result in macromolecule structure and function if the world was based on a small nonpolar lipid
Changes is macro molecule structures are expected among other things.
Briefing :There would be significant changes to proteins and carbohydrates if the Earth were built on a tiny non-polar lipid rather than water. Basic alterations in an organism might include solubility, catabolism, metabolism, and absorption. Because there aren't enough dissolved media, a lot of water-soluble material would become immobile.
However, other stuff that is soluble in fat will be very mobile and well absorbed. Sessile organisms that rely on nutrients that are dissolved in water for absorption, such as trees, will lose this capability. Finally, abiotic variables like precipitation and rock weathering will be affected. There will no longer be polar cap freezing or ice melting, and there will be an influx of a non-evaporating liquid.

What is the function of the structure identified by the red arrow?
Answer:
The structure shown by the red arrow is cell membrane.
In biology, cell membrane refers to the thin layer, which develops the external boundary of a living cell. It has three primary functions, which are as follows:
1. It comprises channels and receptors, which permits particular molecules like nutrients, ions, metabolic components, and wastes to pass between the cell and the outside environment.
2. It prevents toxic components from entering the cell.
3. They distinguish essential but incompatible metabolic procedures conducted within the cell.
Explanation:
The function of the structure identified by the red arrow is to store the genetic material (this structure is the cell nucleus).
The cell nucleus is an organelle found in eukaryotic organisms whose function is to store the genetic material (DNA).The DNA within the cell nucleus contains genes that are expressed during transcription and translation to produce proteins.The differential expression of genes determines the phenotypic features of cells.In conclusion, the function of the structure identified by the red arrow is to store the genetic material (this structure is the cell nucleus).

inhibition of proteolysis enhances aluminum-induced perikaryal neurofilament accumulation but does not enhance tau accumulation
AlCl₃-induced aberrant phosphorylation of Tau is degraded by the ubiquitin-proteasome pathway (UPP), however this process is site-specific and varies in different types of cells.
Why does aluminum cause an increase in perikaryal neurofilaments but not tau accumulation?Phosphorylated neurofilament (NF) epitopes are typically clustered within the axonal cytoskeleton of NB₂a/d₁ cells, as has been seen for neurons in situ. However, following exposure to aluminum salts and proteolysis inhibition, accumulations of phosphorylated NFs form in NB₂a/d1 perikarya. In the current study, we found that perikarya of cells exposed to both aluminum and the protease inhibitor C₁ (also known as "AllNal") were more strongly labeled by monoclonal antibodies directed against both non-phosphorylated and phosphorylated epitopes than cells treated with either aluminum or the protease inhibitor alone.
We also immunostained cells treated under these conditions with monoclonal antibodies targeted against phosphate-insensitive (5E2) and phosphorylated (PHF-1) tau epitopes because these monoclonal antibodies cross-react with tau. A rise in 5E2 immunoreactivity indicated that aluminum therapy, but not C₁ treatment, caused an accumulation of total tau isoforms. PHF-1 immunoreactivity was not increased by either medication, whether used alone or in combination. According to these results, changes in immunoreactivity with SMI antibodies corresponded to a rise in NF epitopes. Analyses using an immunoblot confirmed this. These findings suggest that deficiencies in proteolytic mechanisms contribute to the development of neurofibrillary pathology and highlight the possibility of multiple etiologies for human neuropathological conditions because proteolysis is apparently essential for maintaining the normal distribution patterns of phosphorylated NF epitopes.

The oldest rocks on Earth are REALLY old - about 4.6 billion years old - but all of the oldest ones are found on land and not in the ocean. Around the mid-ocean ridge, the rocks are very young (only 9 million years old). Why is there a difference in the ages of rocks on land versus in the ocean?
Why are the oldest rocks on the ocean floor only 200 million years old while the oldest rocks on the continents are almost 4 billion years old?
Explanation: The oldest oceanic crust is about 260 million years old. This sounds old but is actually very young compared to the oldest continental rocks, which are 4 billion years old. ... It is due to the process of subduction; oceanic crust tends to get colder and denser with age as it spreads off the mid-ocean ridges.

(True/False) A human’s cells do not all have the same DNA.
Answer: false
Explanation:
All has same DNA
It is false that human cells do not all have the same DNA.
DNA:Deoxyribonucleic acid, also called DNA, is a biological molecule that stores genetic information in living cells. The DNA contains genes responsible for inheritance of certain traits. However, in humans, all cells contain the same DNA sequence. Specialization occurs because the DNA are expressed differently and at different times.Therefore, it is false that human cells do not all have the same DNA.

Answer True or False.
Cancer cells show no contact inhibition. Therefore, cell growth and division does not stop.
True
False
Answer:
Cancer cells are immortal and keep on dividing for an unlimited number of times. Cancer cells pile on top of one another and grow in multiple layers, forming a tumor. Cancer cells keep on dividing, even when stimulatory growth factors are absent, and they do not respond to inhibitory growth factors.
The statement "Cancer cells show no contact inhibition. Therefore, cell growth and division do not stop" is true.
What are cancer cells?
Cancer cells are abnormal cells that grow rapidly without stopping. These cells cause tumors because of unstoppable cell growth.
The amount of times that cancer cells can divide is infinite because they are immortal. A tumor is created when cancer cells stack on top of one another and grow in numerous layers.
Even in the absence of stimulator growth factors, cancer cells continue to divide and do not react to inhibitory growth factors. No contact inhibition is a mechanism that is used for stropping cancer and this inhibition is not present in cancer cells, that's why they divide rapidly.
Therefore, the statement is true.

people of india confound traditional racial categories because they fit most closely in terms of biological characteristics with people from europe, yet many have dark skin. '
Indians may closely resemble Europeans in terms of biological traits due to genetic allele frequencies.
The oldest skeleton from Europe that has been found so far is anatomically modern and dates to between 34,000 and 36,000 years ago. It was found in Romania's Carpathian Mountains. Conclusions drawn from the fossil evidence are supported and expanded by data already available on human genetic variation.
The conventional racial divisions, according to some observers, is biologically and genetically justified by these patterns of variation. According to their claims, the distribution of humans among sub-Saharan Africans, European, West Asians, and North Africans, Eastern Asians, Polynesians and other Oceanian residents, and Native Americans largely corresponds to the grouping of the continents.
