A train travels 120km in 2 hours and 30 minutes. What is its average speed in meters per second?

Answers

Answer 1
Answer:

Answer:

.8 miles a minute

Explanation:

convert 2 1/2 hours to minutes and divide it by 120

Answer 2
Answer: 13.3 m/sec
(change 120 km into meters, making it 120,000 m. change 2 hours and 30 min into sec, making it 9,000 sec. v=d/t so you divide meters by seconds, and get 13.3 m/s)

Draw a circle and label the diagram below using the following words polymer and monomer

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the diagram mentioned in the question. However, when the diagram is viewed, identify/label single unit (of a molecule) that is repeated as monomer. The entire stretch of the repeated units (monomers) should be labelled as polymer.

NOTE:

Monomers are simple units/building blocks of polymers. For example, glucose molecule (in a dextran) is a monomer and ethene (in polythene) is a monomer

Polymers are large molecules consisting of repeated units of monomers. Examples are polysaccharides (such as dextran) and polythene

Which of these would most likely happen if there is a sudden increase in the number of sunspots?A. summers would become colder
B. Earth's tilt on its axis would decrease
C. Earth's climate would become warmer
D. length of days and nights would increase

Answers

Which of these would most likely happen if there is a sudden increase in the number of sunspots?

C. Earth's climate would become warmer

The correct answer is option C.

The sudden increase in sunspots will make the Earth more warmer because the more the sunspots, more energy is delivered to the atmosphere. This increases the global temperatures of the Earth.

Answer:

The correct answer is C.

Explanation:

Sunspots increase and decrease through an average cycle of eleven years.

There is a debate of how much this sunspot would affect the earth`s temperature, the earth`s climate is sensitive to very weak changes in the Sun`s energy. During maximum sunspot activity, there`s a very slight increase in the energy output of the sun. Ultraviolet radiation increases during high sunspot activity, and this can have a large effect on Earth`s atmosphere.

Strepsirhines have a special lower incisor called a Group of answer choices tooth comb. diastema. two-ridge tooth. bilophodont.

Answers

Answer: tooth comb

Explanation: Strepsirhines  are any member of the clade (a group of animals or other organisms derived from a common ancestor species) Strepsirrhini, one of the two suborders (a taxonomic category below order and above infraorder) of primates. They have a special lower incisor called a tooth comb which consists of long, flat teeth with microscopic grooves, and used for grooming the fur.

Final answer:

Strepsirhines, a suborder of primates that includes lemurs and lorises, have a distinct structure called a toothcomb, made up of closely packed lower incisors that stick out from the mouth. Apart from other unique features like a grooming claw, this toothcomb sets strepsirhines apart from other primates.

Explanation:

Strepsirhines, a suborder of primates that includes lemurs and lorises, have unique anatomical features that set them apart from other primates. They have incisors in their lower jaw that are packed closely together and stick out from the mouth in a structure called a toothcomb. This toothcomb, in combination with a clawlike second toe known as a grooming claw, is a hallmark of strepsirhines. The toothcomb is used for grooming - removing debris and parasites from their fur - and is also thought to assist in feeding.

Unlike the majority of mammals, which are diphyodonts and have two sets of teeth in their lifetime, strepsirhines' teeth do not necessarily get replaced. Strepsirhines are found primarily in the 'Old World' - parts of Africa, Asia, and Europe - though a number of species are indigenous to islands such as Madagascar.

Plants use carbohydrates to build things such as cellulose. How do plants acquire these building blocks to build mass?a. They absorb carbohydrates through the soil.
b. They absorb dissolved carbohydrates via water.
c. They make carbohydrates through the process of photosynthesis.
d. They make carbohydrates through the process of cellular respiration.

Answers

I believe the correct response would be C. Plants acquire carbohydrates by producing them through the process of photosynthesis. This allows plants to then use the formed carbohydrates to build structural polymers, such as cellulose.

Whas the complimentey DNA strand for the folloing DNA sequence AATTCGGGGTTT

Answers

Answer:

DNA: TTAAGCCCCAAA

RNA: UUAAGCCCCAAA

Explanation:

A binds with T (Apples on Trees)

C binds with G (Cows eat Grass)

So complementary sequence would be TTAAGCCCCAAA

For RNA sequence:

For RNA:

A binds with U

T binds with A

C binds with G

So RNA complementary will be UUAAGCCCCAAA
