GIVING BRAINLY! A car started accelerating and it gained speed at 2 m/s2. The car had a mass of 200 kilograms; calculate the average force the car was traveling at.

Answer: ____ Newtons

Answers

Answer:

100 Newtons

Explanation:

The car was traveling at an average force of 400 Newtons. This is the force that was being applied to the car to cause it to accelerate at a rate of 2 meters per second squared.

What is force?

In physics, force is a measure of the interaction between two objects that can cause a change in the motion of one or both objects. Forces can be classified as either contact forces, which involve physical contact between two objects, or non-contact forces, which involve the interaction of objects without physical contact.

To calculate the average force that the car was traveling at, you can use the equation for average force:

average force = mass x acceleration

Plugging in the values given, you get:

average force = 200 kg x 2 m/s2 = 400 N

Which RNA molecule is involved in translating a short sequence of RNA into an amino acid, acting like a molecular Rosetta stone?
a
snRNA

b
tRNA

c
mRNA

d
rRNA

Answers

The RNA molecule that is involved in translating a short sequence of RNA into an amino acid is tRNA (Option b). This molecule (tRNA) is fundamental to link the genetic information from DNA to protein.

During gene transcription, a fragment of DNA called gene is used as a template to create a complementary messenger RNA (mRNA).

Subsequently, this mRNA is n then used as template to create a polypeptide (i.e., a protein) by a process called translation.

During translation, triplets of nucleotides or 'codons' in the mRNA sequence interact with anticodons of the transfer RNAs (tRNAs), which then specify the linear order of amino acids that will be added to the growing polypeptide.

When the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere. This phenomenon is known as

- climate change
- global warming
- greenhouse effect
- positive feedback

Answers

Answer:

Greenhouse effect

Explanation:

When the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere; this phenomenon is known as the "greenhouse effect," which is present in the third option.

What is the greenhouse effect?

When solar energy strikes the earth, some of it is reflected back and some is trapped in the atmosphere's gaseous layer, such as carbon dioxide; water vapor traps this radiation and warms the earth. Global warming is seen as having serious consequences due to its warming nature, including the melting of the polar ice, agricultural destruction, and so on.

Hence, when the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere; this phenomenon is known as the "greenhouse effect," which is present in the third option.

show that respiratory gaseous exchange in a rabbit occurs at the level of lungs​

Answers

No single animal model can reproduce all of the human features of both acute and chronic lung diseases. However, the rabbit is a reliable model and clinically relevant facsimile of human disease. The similarities between rabbits and humans in terms of airway anatomy and responses to inflammatory mediators highlight the value of this species in the investigation of lung disease pathophysiology and in the development of therapeutic agents. The inflammatory responses shown by the rabbit model, especially in the case of asthma, are comparable with those that occur in humans. The allergic rabbit model has been used extensively in drug screening tests, and this model and humans appear to be sensitive to similar drugs. In addition, recent studies have shown that the rabbit serves as a good platform for cell delivery for the purpose of stem-cell-based therapy.

Answers

Answer:

I would say Artificial Selection.

Explanation:

Khan Academy defines Artificial Selection as: "Artificial selection, also called "selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection." The other options seem a bit irrelevant to the question.

Answer:

Artificial Selection

Explanation:

Artificial selection involves selecting breeding. This is when farmers breed two plants which bear the largest, sweetest or tastiest fruits or which give high yields of the crops. The same process happens in cows, where farmers select animals to breed, based on high milk yield, or meat production.

However, farmers are becoming to think more differently in order to improve the welfare of animals. Instead of high yields, they are looking to increase disease resistance among animals and plants alike. Banana breeders are looking towards wilder plants with more disease resistance. But all in all, it is artificial selection. It's not bad, as it increases nutritional values for us humans.
