How to find the formula for the nth term

snow_tiger [21]

“The nth term of the following types of sequences can be found out using the following Formulas:

1.Arithmetic Progression(AP) : here, the consecutive terms differ by a common difference (d).

tn= a+(n-1)d

Where,

a= is the first term of the sequence,

n= nth term

d= common difference

2. Geometric Progression(GP):

Here, the consequtive terms differ by a common ratio (r).

Tn= ar^(n-1)

where,

a = first term

r = common ratio

tn= nth term

3.Harmonic Progression (H.P):

It is the reciprocal of AP.

To find nth term of a HP, first convert it into AP and then apply the tn formula for the sequence and take the reciprocal of the obtained tn again.

Hope the answer helps you!!”

To test the hypothesis that mussels are osmoconformers, researchers exposed mussels to water of varying osmolarities and then dr

inn [45]

The question is incomplete, I included an attachment that completes the question as well as show the options to be chosen from.

Answer: YES, SUPPORTED

Explanation: When we talk of Osmoconformers, we are talking of the organisms that live in the marine habitat.

These Osmoconformers have the tendency of maintaining their internal fluid isotonic that is isotonic to their external environment in church they live. They have an osmotic pressure that is equal to the osmotic pressure of their surrounding environment.

In the table provided in the attachment section,it clearly stated as we can see the increase in osmolarity of water,the haemolymph osmolarity increase in order to maintain isotonic realtion so that,there will be no much exosmosis (osmosis).

"One of the two major systems that are affected by the stress response is the ____________, which results in increased productio

MAXImum [283]

Answer:

The correct answer is the endocrine system.

Explanation:

The sympathetic division of the autonomic nervous system and the endocrine system are the two prime systems that take part in the stress response.

At the time of acute or chronic stress, the endocrine system first makes the hypothalamus to discharge CRH or corticotropin-releasing hormone into the bloodstream. The release of CRH further makes the anterior pituitary to discharge ACTH or adrenocorticotropic hormone into the blood. This further stimulates the adrenal cortex to discharge cortisol, that is, one of the glucocorticoid hormone into the bloodstream.

The cortisol finally makes the organs and tissues present within the body to effectively cope up with the initial stress stimulus.

Classify the following gas planets as terrestrial planets or gas giants

kkurt [141]

<h2>Answer:</h2><h3>Part 1.</h3><h3> Celestial body A is the largest planet in the solar system.</h3>

It is Jupiter which is a <u>Gas giants.</u>

Jupiter is mostly made of gas.

According to above statement, It is the Jupiter which largest planet in our solar system. Jupiter's mass is more than 300 times that of Earth, and its diameter, d, at 140,000 km.

<h3>Part 2. </h3><h3>Celestial body C has optimum conditions to sustain life.</h3>

It is earth which is a<u> terrestrial planet.</u>
Because it is mostly made of silicate rocks and minerals.

According to statement, earth is that planet because it has living optimum conditions. Like the oxygen concentration, water, plants etc.

Celestial body E has the most volcanoes in our solar system apart from earth. It is the second closest planet to the sun.

It is Venus and it is a<u> terrestrial planet.</u>

Venus orbits sun every 224.7 Earth days.

It has the longest rotation period of any planet and it rotates in opposite direction to most of the planets in the Solar System.

<h3>Part 4.</h3><h3>Celestial body H is the second largest planet in the solar system and has visible rings.</h3>

It is Saturn which is a <u>gas giant.</u>
Because it is mostly consists of gases and it also has ring of gases around itself.

it is 9.4 times as large as the Earth. It also has a large and bright ring system.

<h3>Part 5.</h3><h3>Celestial body D has 17 times more mass than earth and has gravity that is 1.14 times that of earth. </h3>

It is Neptune and it is a <u>gas giant</u>.
It has mostly gaseous composition, such as hydrogen and helium.

Neptune is the eighth and farthest known planet of the Solar System. It is also the third most massive planet.

<h3>Part 6.</h3><h3>Celestial body G has a core that consists of iron sulfide mixed with nickel and is the second smallest planet in the solar system.</h3>

It is mars and it is a<u> terrestrial planet</u>.
Mars is the second smallest planet while mercury is first smallest planet after the exclusion of Pluto from solar system.

The surface of mars is covered by talcum powder type dust. It contains elements besides silicon and oxygen, are iron, magnesium, aluminum, calcium, and potassium.

<h3>Part 7.</h3><h3>Celestial body I had a core composed of nickel iron alloy rock surrounded by an outer layer of hot fluid. The fluid contains water, ammonia, and methane body I has 27 moons .</h3>

This is Uranus and it is a<u> gas giant</u>.
is the seventh planet of the Solar System.

According to radius, it is on third number and according to mass it is forth largest planet. Its composition is more similar to Neptune.
