Elements W and Z are metals, Elements X and Y are nonmetals, but Element X is in Group 18 (noble gas). Therefore, the correct option is option A.

What are periodic properties?

Periodic Properties: Periodic properties are those that exhibit a regular gradation as we travel from left to right inside a period either from top to bottom inside a group and are either directly or indirectly connected to their electrical arrangement.

Atomic size, ionization energy, electron affinity, electronegativity, polarity, density, atomic volume, melting, and other essential periodic features are only a few. Elements W and Z are metals, Elements X and Y are nonmetals, but Element X is in Group 18 (noble gas).

Therefore, the correct option is option A.

I'm in 9th grade going into 10th should I take chemistry or geoscience?
and online or in-person

Answers

I’m not too sure what geoscience is, is it like earth science or..? Anyways I took chemistry online this year and I think it’s ok to say I would have rather taken it in person, just because chemistry can sometimes be confusing -at least for me, and I’m generally a smart person oof. Ik my answer may be biased because i took earth science in middle school and chemistry now (10th grade), but I would say take chemistry. If you take chemistry now then a LOT of things will make sense and if you do geoscience in 11th grade or smth it may be a lot easier to understand.

Answer:

I am honestly having the same questions. I think which one sounds the most for your level or onto collage applications! Now I was thinking about online for some people it's easy. But it's easily distracted. You have more freedom to roam the internet. Scroll through Insta. Or play video games. Now that seems really awesome. But my grandma says 9th grade is the most important year. It determines whether if you need help or if you fail you spend the res of your years catching up. I also am going into 10th and these words are scary.

Explanation:

I don't want to go to school because I feel once the friends I made online see me.. They will change their minds.. But even though I know going in person where I pay attention better is the best shot.

Anyways hope this helped have a wonderful day! <33

What is the correct mRNA transcription of the following DNA sequence? ATGGCACCTTAC
A. UACCGUGGAAUG
B. AUGGCACCUUAC
C. CAUUCCACGGUA
D. CATTCCACGGTA

Answers

Answer: A

Why? None of the other sequences will match up correctly

The process of transcription produces the mRNA sequence from the DNA. The mRNA transcription of ATGGCACCTTAC will be UACCGUGGAAUG. Thus, option A is correct.

What is mRNA transcription?

Transcription is the process of the formation of mRNA from the replicated DNA strand of the cell. It produces an mRNA transcript that is a single strand and further codes for amino acids.

The mRNA transcript forms by the base pairing with the DNA template. If the DNA sequence is ATGGCACCTTAC then according to the base pairing rule the adenine (A) pairs with uracil (U) in mRNA, and guanine (G) pairs with cytosine (C). In mRNA, the adenine binds with uracil and not thymine, and hence A pairs with U, whereas the G-C bond remains the same.

The DNA strand: ATGGCACCTTAC

The mRNA sequence will be:  UACCGUGGAAUG

Therefore, option A. UACCGUGGAAUG is the mRNA transcript.
