What is the role of each cell part and biomolecule during DNA replication?

Jlenok [28]

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

Name and describe the phase change that occurs when solid carbon dioxide (dry ice) is placed in an open container at room temper

Valentin [98]

If you put a lump of solid carbon dioxide (dry ice) in a paper cup or
on a paper plate on the kitchen counter, it gets smaller and smaller
and finally it just disappears, but you never see a puddle around it
like you would with regular ice!

Carbon dioxide has no liquid phase when the pressure on it is less than
about 5 times normal atmospheric pressure. So in the kind of pressure
that we like to live in, dry ice goes straight to gas when it melts. That kind
of behavior is called "sublimation", and we say that the dry ice "sublimes".

Every substance has some pressure limit like that. For water, it's 0.006 of
normal atmospheric pressure. At any pressure lower than that, liquid water
can't exist, and an ice cube sublimes ... it melts directly into water vapor
without a puddle.

What does it mean that earlobe attachment is a continuous trait?

mylen [45]

Answer:

If you decided that the continuous spectrum of earlobe shape was a more accurate way to describe the variation, you aren’t alone. Family and genetic studies show that earlobe attachment is actually not a simple trait, but rather a complex trait, affected by multiple genes and environmental factors.

Increasing temperatures in the atmosphere have caused the temperature of the oceans to _______, leading to more powerful tropica

Serjik [45]

Answer No 1)

Increasing temperatures in the atmosphere have caused the temperature of the oceans to increase leading to more powerful tropical storms.

Approximately 25 percent of carbon dioxide emitted into the atmosphere is absorbed in the oceans.

Waste water treatment is critical to removing pollutants from contaminated water by using physical, chemical, or biological processes.

Water pollution can come from the decomposition of dead organic matter or animal waste in waterways.

Water pollution increases the salinity and slows down major ocean currents that are responsible for regulating Earth's climate.

Explanation:

The devastating effects of global warming effects both the land and the aquatic biomes.

The excess carbon dioxide produced as a result of global warming is absorbed by the oceans. This imposes a serious threat on the biodiversity of the aquatic life. The dead organism also produce pollution when they degrade in the oceans.

It is essential that before ocean water is used for any kind of consumption, the water be effectively treated to remove all kinds of toxicity from it.

Answer 2)

Water quality can be improved through conservation by :

a) using less amount of water for house-hold purposes: In our daily lives, humans use extra amounts of water fro house- hold activities such as while washing clothes or washing dishes. It should be ensured that we use a reasonable amount of water for every house-hold activity.

b) Fix the leakages: Majority of the houses in a society will not be concerned about a minor water leakage from taps, pipes etc. But it is essential to conserve every drop of water and these leakages need to be fixed. The more water we conserve, the more improved quality water will be available.

MULTIPLE CHOICE

mojhsa [17]

Answer:

The correct answer is the growth of the offspring to adulthood.

Explanation:

A life cycle is illustrated as the stages of development, which take place during the lifetime of an organism. A life cycle ceases with the death of an organism. Generally, the animals and plants go through three fundamental stages in their life cycles, beginning as a seed or fertilized egg, developing into an undeveloped juvenile, and eventually turning into an adult.

During the stage of adulthood, a species will reproduce, forming a new generation. A life cycle can constitute more than three fundamental stages on the basis of the species. For example, the life cycle of a human being comprises five main stages.
