the DNA is tightly wrapped around histone proteins in a chromosome why is this packaging necessary?
1. Because the dna molecules will down without it .
2. Because the dna molecules will dissolve in cell water .
3.) because the long dna will fit inside the cell.
4.) because the dna needs to attach itself to support .

Answers

Answer 1

Answer:

3.) because the long dna will not fit inside the cell.

Explanation:

This question is oddly written. At first glance, I can tell it's not 1 or 2 because DNA doesn't "dissolve" in cell "water", nor will it "down" (I'm assuming this means "drown"?).

The main reasons for DNA packaging are so that the DNA can fit into the cell, and so it's protected from damage. The DNA is vital to the cell, so it protects it by coiling it up. Coiling and packaging are also important when it comes to gene expression.

When the moon casts its shadow on Earth, a lunar eclipse occurs.

The last option is correct.

How do we explain?

A lunar eclipse happens when the Earth's shadow falls on the moon. This can only happen during a full moon, when the sun, Earth, and moon are perfectly aligned.

The Earth's shadow has two parts: the umbra and the penumbra. The umbra is the darkest part of the shadow, and it is where the moon will completely disappear. The penumbra is the lighter part of the shadow, and it is where the moon will only partially disappear.

Therefore, the last option is correct.

A. A book about planning sexual activities
B. Scientific research on the body

D. An age restricted site showing nudity

Answers

Answer:

B. Scientific research on the body

Explanation:

B is the most plausible answer because option A and D will not answer your research question about sexual hormones (from a scientific perspective) and option C will have information which will not help you make conclusions since newspaper take their information from other sources and sometimes leave out chunk of data or information to fit it in one page.

Round the number 14.587020 to 4 significant digits. a. 14.59 b. 14.58 c. 14.587 d. 15.00 Please select the best answer from the choices provided A B C D

Answers

Answer:

A. 14.59

Explanation:

Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.

Next, we have to know that to round a number;

* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.

* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit

Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant

Hence, 14.587020 will be:

= 14.587020

= 14.58700

= 14.59000

We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right

Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59

Answer:

a.14.59

The Big bang theory is a cosmological model that proposes that the new universe was formed from the expansion of a Larger body having a high level of density and temperature.

The background radiation is a microwave radiation that is studied by astronomers to determine the age of the universe, therefore if microwave radiation has a bright color it will help the astronomers determine the age of the universe easily and also proving that the formation of the universe was from the Big bang.

Hence we can conclude that The bright and astonishingly uniform color of microwave radiation would : make background radiation visible to astronomers studying the age of the universe ( Big bang theory )

Answers

Answer:

Due to the movement of surounding water ijnto the cell.

Explanation:

A red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.

Osmosis is the movement of water that diffuses from a higher water concentration area to a lower water concentration area.

The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic to the red blood cell.The red blood cell will gain water, swell ad then burst.

Thus, a red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.

Rabbits can be best described as primary consumers. The correct option is b.

What are primary consumers?

The 2nd trophic level is comprised of primary consumers. They are also known as herbivores. They just feed primary producers, including such plants or algae. A grasshopper, for example, is a primary consumer in the Everglades.

Primary consumers are rabbits because they are the first step up from autotrophs. Autotrophs, such as grass, are eaten by primary consumers such as rabbits.

The animals that eat the primary consumers are known as secondary consumers.

Herbivores are the primary consumers of plants. Primary consumers include caterpillars, insects, grasshoppers, termites, and hummingbirds, which only eat autotrophs (plants).

Rabbits are herbivores because they only eat plants - and herbivores are consumers because they eat plants to survive. Consumers include deer, grasshoppers, and rabbits.
