it prevents the Earth from ultraviolet radiation and other harmful substances from space. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds
why are all bacteria microscopic and why is virus not a living thing?
Answer:
the world may not know why bacteria is microscopic but we do know that viruses are a living orgasm
Explanation:
example : coronavirus can move by its own because its a living orgasm but humans make it easy to travel by contact with other human. Also the spikes in the coronavirus is the cellular membran (membrana cellular) and it uses the spikes to inject other cells thus the need for handsanitiser and soap to destroy the cellular membran (membrana cellular) and kill the cell. stay safe :)

1. Carbon is essential to life on Earth. One reason it is so vital is that it is able to form bonds with many other
elements and with itself. Inside living things, there are many compounds based on carbon, including fats,
sugars, starches and oils. There are four main types of carbon compounds: carbohydrates, lipids, proteins
and nucleic acids. Each of these has important roles in living organisms. Proteins make up muscles and
carry messages, and carbohydrates give cells energy.

How does osmosis affect plants?
Answer:
Plant cells are enclosed by a rigid cell wall. When the plant cell is placed in a hypotonic solution, it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become 'turgid', i.e. swollen and hard.

what type of structures modify and distribute polypeptides through the cell"
Answer:
Quaternary structure
Explanation:
Quaternary structure insinuates the number and game-plan of the individual polypeptide chains. Each polypeptide is suggested as a subunit of the protein. Comparative powers and bonds that make tertiary structure moreover hold subunits together in a consistent eccentric to shape the complete protein.

Determine whether each statement refers to species diversity or genetic diversity.
Every organism in an ecosystem relies on other species for survival:__________
Reduced options for mates can lead to inbreeding:
Decreased diversity can lead to increased susceptibility to disease:___________
The loss of a producer could result in the loss of consumers:___________
When a population becomes small, diversity is lost:
Answer:
1. species diversity
2. genetic
3. genetic
4. species
5. genetic
Explanation:
1 and 4th shows species diversity whereas 2, 3, 5 refers to genetic diversity.
What is the difference between genetic and species diversity?The primary difference between genetic diversity and species diversity is that genetic diversity refers to differences in DNA that may be found across individuals of the same species
Whereas species diversity refers to the number of different species that can be found in a certain region. The term "ecological diversity" refers to the range of ecosystems that may be found in a certain region.
A given species' capacity to adapt and spread across a variety of environments is facilitated by genetic diversity. Diversity of species fosters biotic interactions and community stability.

Explain how the reduction and rearrangement are accomplished in meiosis.
Answer:
Reduction is accomplished by (homologous) chromosomes pairing and then separating to move to opposite poles during the 1st meiotic division. ... Rearrangement is achieved by the chromosomes crossing over into random alignments of tetrads, resulting in the genetic variation of the offspring.
Hope It Helps
Pls Mark As BrainLiest
The type of cell division that allows the formation of cells with half of the genetic information of the dividing cell is known as meiosis, the reduction and rearrangement are accomplished in the following way:
Chromosome reduction occurs as a cell division process in which a diploid (2n) cell undergoes two successive divisions, generating haploid (n) cells.These cells called gametes have half the DNA of the rest of the individual's cells, this half of DNA is not random, but is precisely a complete chromosomal set.This halving allows the number of chromosomes of the species to be maintained at fertilization.Rearrangement occurs before chromosomes separate, corresponding sections of chromosomes can change, or cross, between the pair.Through recombination and random segregation, each pair of homologs obtains a mixed paternal and maternal chromosome, thus producing a new haploid chromosome set or set in which new combinations of genes have originated.The rearrangement of DNA increases genetic diversity within a population by passing genetic information to the next generation, which is not completely identical to that of the father.Therefore, we can conclude that meiosis is one of the ways in which cells divide, characterized by giving rise to daughter cells that are genetically different from the cell that originated them through chromosome reduction and rearrangement.

The regularity of El Niño weather events is determined by
A the amount of gases that volcanoes create each year on the seafloor near Australia.
B changes in the size of a warm podl of water in the seas near Indonesia.
C a decrease in the frozen glaciers at Earth's poles.
D the magnetic strength of Earth's inner core.
Answer: The answer is B
Explanation:
This is a known knowledge about how hurricanes form. It's the same with El Nino, Good Luck.
A decrease in the frozen glaciers at Earth's poles can be the event by which we can determine the regularity. Correct option is C.
The term El Niño refers to a warming of the ocean surface in the central and eastern tropical Pacific Ocean.
Niño occurs when warm water builds up along the equator in the eastern Pacific areas. The warm ocean surface increase the temperature in the atmosphere, which allows moisture-rich air to rise and develop into rainstorms.
Therefore, a decrease in the frozen glaciers at Earth's poles can be the event by which we can determine the regularity.
