What is a DNA molecule?

A DNA molecule may be defined as a molecule that comprises the biological instructions that construct each species unique in terms of genetic sequences.

The nucleotide bases are always bound to each other in a complementary form, i.e. A is bonded to T with the help of two hydrogen bonds, while C is bonded to G with the help of three hydrogen bonds.

Apart from this, according to Chargaff's rule, the amount of adenine is always equal to the amount of thymine, while the amount of guanine is always equal to the amount of cytosine.

Therefore, it is well described above.

Answer:

Natural fiber smell like paper whereas artificial fiber smells like an acid.

Explanation:

We can distinguish between natural and artificial fibers by observing the smell produced when burnt because both produces different types of smell when burnt. When the artificial fibers are burn, it produces acid or chemical like odor and leaving a plastic like bead while on the other hand, when the natural fiber burn, it produces smell of burning paper or hair and leaving ash of soft and grey colour.

An underground water supply has a depth of 200 m of water. Water seeps in at the rate of 4 cm / year . Water is pumped out at the rate of 1m / year . How long will this water supply last? To find the net water loss from an underground water supply, subtract the amount that seeps into the water sup ply from the amount removed from the water supply. How long will the water supply last if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year ?

Answers

Answer:

208 years.

Explanation:

The water supply last for 208 years if the water seeps in at the rate of 4 cm / year  and water is pumped out at the rate of 1m / year. The water supply last forever if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year because the same amount of water enters the underground which can be pumped from the soil. If more water is extracted from the soil as compared to it seeps, so with the passage of time water concentration in the soil decreases and in the last it disappeared.

it occurs in two stages: transcription and translation

explanation:

transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. it includes three steps: initiation, elongation, and termination. after the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm.translation occurs at the ribosome, which consists of rRNA and proteins. in translation, the instructions in mRNA are read, and tRNA brings the correct sequence of amino acids to the ribosome. then, rRNA helps bonds form between the amino acids, producing a polypeptide chain.

Describe how people change their body shapes (not their clothes) when they are very hot and when they are very cold. Use your knowledge of surface area : volume ratios to explain why we do this.

Answers

Answer:

This quesiton is unclear

Explanation:

The body has negtive feedback loops that either vasoconstrict (preserving heat by lessening the surface area of blood vessels so they are exposed to less cold and release less heat) and vasodilation, where blood vessels are expanded and have higher surface areas so the body hopes to lose more heat to cool down.

If this is purely body language (like going into a fetal position when its cold: to lessen the surface area exposed to the cold temperature and lose less heat, imagine an ice cube vs. a long thin tube of ice with equal volume, the cube will last longer. Similarly our bodies would spread out to release more heat (unless there was sun) this is to expose the most surface area, allowing our body to release the most heat. Note: this is pretty insignificant change, and in extreme temperatures will likely not help, but it does contribute.

When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective.

How would you expect the number of births to compare to the number of deaths in a population that was changing?

Answers

Population Growth - Basic Information
All populations change in size with time
- if births exceed deaths, the population grows
- if deaths exceed births, the population shrinks
- only when births equal deaths does the population stay the same
Other Population Growth Factors
Populations can also change size if organisms move in (immigration) or leave (emigration)

Putting It All Together
We can write a simple equation to show population growth as:

Change in Population Size = (Births + Immigration) - (Deaths + Emigration)

Expressing Population Changes as a Percentage
Suppose we had a population of 100,000 individuals. Suppose in one year there were 1000 births, and 500 deaths.
What percentage of the population were births?
1000/100,000 = 0.01, or in percentage terms, this is 1% of the population.

What percentage of the population were deaths?
500/100,000 = 0.005, or in percentage terms, this is 0.5% of the population.

Assume immigration equals emigration. If so, then they cancel out of our population equation. We'll come back to
this assumption later.

Now, subtract deaths from births but express as a percentage:
1000-500/100,000 = 500/100,000 = 0.005, or 0.5% net growth

Thus, this population would be growing by 0.5% this first year. That means that after one year, there will be 500 more
individuals than the previous year. So, after one year, the population would be 100,500 individuals.

The Net Reproductive Rate
The net reproductive rate (r) is the percentage growth after accounting for births and deaths. In the example above, the population reproductive rate is 0.5%/yr.

Net reproductive rate (r) is calculated as: r = (births-deaths)/population size or to get in percentage terms, just multiply by 100.

Suppose we came back many years later, the net reproductive rate was still the same, but now the population had grown to 1,000,000. How many new individuals would be added each year now? Simply multiply the population by the reproductive rate:
1,000,000 x 0.05 (which is 0.5%) = 50,000

This means that now 50,000 new individuals are added in one year!! The net reproductive rate is the same as before, but because
the population is so much bigger, many more individuals are added.

Exponential Growth
If a population grows by a constant percentage per year, this eventually adds up to what we call exponential growth. In other words, the larger the population grows, the faster it grows!! A curve of exponential growth is an upward sweeping growth curve.

How are the Hawaiian honeycreepers an example of adaptive radiation?



There were a large variety of honeycreepers that first inhabited the island. They found many different niches, so they were all able to survive.


The honeycreepers that first inhabited the island were able to adapt as the island changed, so that population of birds was able to survive.


There was a diversification of honeycreepers (each with different beak shapes) to help fill various ecological niches.

Answers

Answer: In adaptive radiation, many different species evolve from a single ancestor species. Each new species evolves to exploit a different niche, such as food source. In the example above, Hawaiian honeycreepers evolved a range of bill forms in response to available food sources on the Hawaiian archipelago. The honeycreepers dispersed from one founder species, and evolved in response to natural selection based on different food sources in their isolated habitats provided by water. Seed-eating birds evolved thick, short beaks.
