why virus is imortal?

Answers

Answer:

Strictly speaking, viruses can't die, for the simple reason that they aren't alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can't thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.

Explanation:

Answer:

A flu is a virus and the reason that you have to get flu shots every year is because every time a virus enters a host it is mutated by the antibodies, cells and biology of that host, so it can be passed on to another host who may not be immune to every part of this NEW virus.

What happens to the water cycle when the temperature increases?

Answers

Answer:

climate change

Explanation:

because as air temperatures change more water evaporates into the air

Climate change is likely causing parts of the water cycle to speed up as warming global temperatures increase the rate of evaporation worldwide. More evaporation is causing more precipitation, on average.

state 4 ways by which through which a soil is depleted

Answers

Answer:

Explanation:

Leaching – Plant nutrients are lost beyond the reach of plant roots. Usually caused by excessive rainfall washing nutrients deep down into sub-soil beyond new roots reach.

Soil erosion – Top soil is lost by the agent of erosion e.g. wind, water.

Monocropping – This utilizes only specific nutrients from a particular zone making it exhausted. -It also causes accumulation of certain pests and diseases.

Continuous cropping –This continuously exhaust the fertility of land unless the the land if fallowed.

Change of soil PH -Use of either acidic or basic fertilizers affect soil pH and Consequently the presence of micro-organisms hence soil fertility affected.

Burning of vegetations –Destroys organic matter and soil structure. Nutrients are lost and soil exposed to erosion.

Accumulation of salts – Common in waterlogged areas and semi-arid areas in which poor drainage causes evaporation during the dry periods, making the soil saline.

Why do you think Flourine is able to pull the electron away from Lithium?

Answers

Answer:

Because of its high electronegativity.

Explanation:

Fluorine has ability to pull the electron from the lithium because of its high electronegativity.

We know that as we move from left to right in periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and electronegativity increases. AS lithium is present on left side of period 2 and fluorine is present on right side of same period. Fluorine is more electronegative while lithium is more electropositive thus fluorine pull the electron from lithium when they combine and form anion while lithium loses its valence electrons and form cation.

How many water (H2O) molecules could you line up end to end in a nanometer?

Answers

Answer:Molecules have size and different molecules are different sizes. When talking about the size of a molecule, most scientists will mention its molecular weight. That is the total weight of all of the atoms in the molecule. So water, which is made up of two hydrogen atoms (1 atomic mass unit each) and one oxygen atom (16 atomic mass units) has a molecular weight of 18 (well, 18.01528 to be exact). Glucose has a molecular weight of 180. DNA, which is very long, can have a molecular weight that is around 1010 (about the weight of one human chromosome).

Which principle states that two species in the same habitat cannot have the same niche?
niche exclusion principle
competitive exclusion principle
habitat exclusion principle
population exclusion principle

Answers

Answer:

competitive

Explanation:

example 1: two male bucks cannot inhabit the same habitat or area because one needs all the females or pride for itself so it chases away the others

The competitive exclusion principle explains that two species occupying the same niche cannot coexist in the long term since competition is created between them for resources.

What is the competitive exclusion principle?

It is a phenomenon that refers to the competition that one species has with another and the dependence of one organism to develop in terms of the other organism.

In competitive exclusion, one species is displaced by another when their niches overlap and compete for the same resources.

Therefore, we can conclude that the competitive exclusion principle establishes that two species that have the same ecological needs cannot live together since they create competition between them for resources.

Becky is experiencing chronic pain from a medical condition that cannot be treated. In order to minimize the long-term emotional response to her pain, she would choose a modification of her a. Parietal cortex. b. Prefrontal cortex. c. Primary somatosensory cortex. d. Dorsal lateral thalamus. e. Posterior cingulate cortex

Answers

Answer:

b. Prefrontal cortex.

Explanation:

The prefrontal cortex is the cerebral cortex that covers the frontal lobe in the brain. The prefrontal cortex plays important roles in pain processing, as well as in pain modulation. In addition, this brain area is connected to other brain regions including the hippocampus, thalamus, amygdala, and further areas of the cerebral neocortex. It has been shown that changes in gene expression patterns, glial cells, neurotransmitters and inflammatory processes are triggered in the prefrontal cortex during both acute and chronic pain, and these alterations are able to modify its functioning, structure, and connectivity.

If you poured the fluids below into a container, which would sink to the bottom?
-water with a density of 1.0 g/cm3

-honey with a density of 1.36 g/cm3
-air with a density of 0.00013 g/cm3

Answers

Answer:

Honey > Water > oil > air

Explanation:

Heavy density will sink and less heavy density will float

So,

Density of honey is highest so, honey will sink

than,

Density of water is higher so, vegetable oil will float

Density of oil is higher so, air will float

Honey > Water > oil > air

What is the central idea of Passage 2?A)Advertising on school buses helps local businesses, but their ads should be monitored.B)Advertising on school buses allows larger numbers of people to see ads, and that amount of exposure leads to profits. C)Advertising on school buses is gaining popularity, but has a long way to go before being widely accepted by the public. D)Advertising on school buses is one way for school districts to make money, and the community may experience benefits as well.(THE PARAGRAPH)18 School buses are carrying more than students these days.19 The vehicles sport fancy advertisements for local businesses and events.20 It's part of the effort for school districts to make money in these budget-strapped times.21 And it is paying off.22 Lewis-Palmer School District 38 made about $8,000 in its first effort last year with eight advertisers and 11 buses. This year, it is expanding.23 "Ultimately we hope to have advertisements on every bus to maximize our income," said Robin Adair, D-38 spokeswoman. The district, which has had $11 million in cuts in recent years, is seeking a $4.5 tax increase in the November election.24 D-38 has 56 buses that collectively travel more than a half million miles a year. That could be a lot of bang for the advertising buck, and a nice amount of change for district coffers. Like Lewis-Palmer, most districts that allow advertising on their buses choose to put the money in general funds to help with such things as higher fuel and utility expenses and increased contributions to pension funds and student activities.25 Other Pikes Peak districts that use their buses as rolling billboards are Colorado Springs School District 11 and Falcon School District 49.
