What Is A Front?-Air Masses And Fronts 9th Grade Science- HELP ASAP

Answers

Answer 1

A air front is typically a transition zone between two unique temperature/humidity. Usually, one front would push the other away (typically if summer is hot, then the warm front will push away the cold, and for the winter, if it's cold, it's the opposite).

A stationary front, on the other hand, is when there is no change in the over all temperature for the region(s), and a occluded front is when the fronts mix, where it is followed by rain and a equillibrium of the temperature, whether to a warmer or cooler overall temperature.

Algae are the primary producer in the trophic levels. Therefore, option "C" is correct.

What are tropic levels?

Tropic levels are the levels or steps in the food chain. In tropic levels, the energy is transferred to different levels through food produced by the lower levels. The source of nutrition varies in different food chains.

There are four types of tropic levels, first primary producers are the autotrophs which produce their own food. Second, are herbivores which consume the autotrophs also called primary consumers. Third are secondary consumers who are carnivores and fourth are the tertiary consumers who are also carnivores.

example:  sun, plants,  deer, and tigers.

Tropic levels play a key role in understanding the flow of energy.

When you speak naturally to children, you can teach them all of the following except
A. words and language in context.
B. behavior skills.
C. listening skills.
D. language and speaking skills.

Answers

Answer: B

Explanation: behaviour is learnt from action not speaking

The right response is C: listening abilities. Adults may teach toddlers a variety of crucial lessons that support language and speech development by speaking naturally to them. Setting a good example for children on how to use language in context is one of the most crucial things adults can do.

What is  the deal with the samples ?

This entails showing them samples of the language to use in various contexts and encouraging them to use the appropriate nouns and verbs. Children benefit from this because it enables them to appropriately grasp and apply the words they hear.

By giving children examples of appropriate behaviour in various contexts, adults may also assist youngsters in developing their social skills. This can involve things like greetings, apologies, or handling situations.disagreements.

Adults may teach kids how to respectfully communicate their thoughts and feelings. Finally, by engaging in conversation with kids and giving them feedback, adults may aid in their language and speaking development.

This might involve things like teaching kids to express themselves clearly and concisely, correcting grammatical errors, and explaining terms and phrases. However, normal conversation is not an effective way to teach listening skills.

The capacity to listen intently, comprehend what is being said, and respond properly are all parts of listening abilities. These abilities cannot be taught through casual conversation; instead, they require deliberate education and practise.

in step 1 of protein synthesis describe two of the differences between the DNA template and its complementary RNA molecule

Answers

Answer:Proteins are synthesised (made) by the ribosomes using messenger RNA transcribed from DNA in the nucleus.

Explanation:

In every eukaryotic cell, such as plants and animals, there is DNA in the nucleus. The nucleus is an area surrounded by a membrane (nuclear membrane) which has some pores for materials to enter and exit, but these are controlled. The DNA is the cell's instructions, it is a series of code that can be transcribed and translated to make proteins. As in the image below DNA is a series of bases attached to a sugar phosphate backbone and bonded to another base pair to made a ladder, this ladder is twisted making the shaped called a double helix . There are four base pairs: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). The bases have bases they bond to making complementary base pairs , A and T bond together while the C and G bond together. on each strand of DNA one end is labelled 5' (read as 5 prime) and other end is the 3'. The 5' end base pairs of one strand are always attached to the 3' end of the complementary strand. Labelling the ends helps us to describe in which direction DNA is read.

Please help me with this

Answers

Answer:

DNA: thymine, deoxyribose, large molecule, stay in the nucleus

RNA: single strand, uracil, leave the nucleus, small molecule

Explanation:

As for single strand, it's well known that DNA has two strands while RNA has one.

For the description that asks about thymine, you have to remember the nucleotide bases in DNA and RNA. Remember that DNA's bases are A, C, T, and G, while RNA has all the same bases except for T (which stands for thymine). In RNA, the thymine is replaced with uracil, usually abbreviated as U. That sorts out the descriptions that ask for thymine and uracil.

To figure out the one that asks for deoxyribose, remember that DNA has deoxyribose and RNA has ribose (hence why DNA is deoxyribonucleic acid while RNA is just ribonucleic acid.)

For the large molecule/small molecule ones and the questions that ask about the size of the molecule, remember that DNA is a way bigger molecule than RNA and that RNA is small enough to leave the nucleus, while DNA is much too valuable to the cell to be able to leave the nucleus.

A reagent is a chemical substance that cause a chemical reaction or used to test the one. In the given activity, different reagents are used to predict the compound. Starch gives blue color on reaction with iodine, glucose will have brick red precipitate with Benedict solution, and proteins will have reddish brown color with Millon's reagent.

Why reagents are used to test compounds?

The reagents when combined with specific compounds performs specific reaction which helps to determine the presence of particular compound.

In the given activity,

If in the first test, if the iodine turns color to blue this will indicate the presence of starch.In the second test, if on adding Benedict solution, brick red precipitates formed, this indicates the presence of glucose.In the third test, on adding Millon's reagent the protein in the solution will form reddish brown color.
