ADNA strand has the sequence GTTCCAGAG. Which is the complementary strand of RNA?
O CAAGGTCTC
O AGGTTCACA
4
O CAAGGUCUC
OTGGAACTCA
Answer:
CAAGGUCUC
Explanation:
To solve this question, we must know the base-paring rules of DNA and RNA.
Here is the following rule for a strand of DNA:
Adenine bonds with thymine
Cytosine bonds with guanine
Now, here is the following rule for a strand of RNA:
Uracil bonds with Adenine
Cytosine bonds with guanine
By the way, the attachments that I provided are resources from my teacher on this topic!
So now that we know the following rules, we can use these rules to find the complementary strand of RNA, and to do this, all we need to do is simply use the base-pairing rules to find the complementary nitrogenous base (adenine, guanine, cytosine, uracil) for RNA.
[tex]GTTCCAGAG[/tex] → [tex]CAAGGUCUC[/tex]
In conclusion, the complementary strand of RNA for the DNA molecule is CAAGGUCUC.
Answer:
A) CAAGGTCT
Explanation:
The answer is A because A = T and C = G in the case of DNA matching. It's not CAAGGUCUG because Uracil is not part of the DNA sequence matching.
Which of the following best describes a community?
Answer: A. an interacting group of populations that occupy the same area.
The best describes a community is it is an interacting group of populations that occupy the same area. The correct option is A.
What is a community?A community, commonly referred to as a biota is a group of organisms that coexist and communicate with one another within a habitat or environment. An ecosystem is made up of both the biotic community and the abiotic components, such as the physical environment.
Savanna is a good illustration. For protection, zebras and wild animals coexist in huge numbers. Herbivores are preyed upon by predators like lions and eagles for food.
There are two types of community:
Major - these are the big ecological unit, that regulates the flow of energy.
Minor - These are small communities that make up big communities.
Thus, the correct option is A. an interacting group of populations that occupy the same area.

Two organisms evolved from a common ancestor. Which process best explains why they now have different characteristics? *
A- extinction
B- metabolism
C- sexual reproduction
D- biological adaption
Answer:
D is the right one i think, biological Adaptation delete this answer if it is wrong
Explanation:
D- Biological adaptation best explains why two organisms evolved from a common ancestor now have different characteristics.
What is Biological adaptation?Biological adaptation refers to the process by which organisms develop traits or characteristics that improve their chances of survival and reproduction in a specific environment.
Over time, as different populations of organisms face different environmental pressures, they may evolve different adaptations that enable them to survive and reproduce more successfully in their respective environments.
This can lead to differences in the characteristics of different populations of organisms that share a common ancestor.
Extinction, metabolism, and sexual reproduction are not processes that directly explain why two organisms evolved different characteristics.
Extinction refers to the process by which species die out, metabolism refers to the chemical processes that occur within living organisms to maintain life, and sexual reproduction involves the exchange of genetic material between individuals, but none of these processes directly explain why two organisms evolved different characteristics from a common ancestor.

What is cytokinesis?Cytokinesis is the final process in the cell cycle, where a cell is ready to divide before it is all the phase of the cell cycle ensuring that the cell has all the components in double amounts.
Before cell division cells spent most of their time in interphase, where the cell synthesis organelle, and protein and doubles its DNA. All the necessary components protein, enzymes, and growth factors for division during this phase.
Cytokinesis is the final step where the cell divide in equal parts if all the steps of the cell cycle are abnormal cell divide into the large and small daughter cell.

When both the P and A site are occupied and a third tRNA anticodon comes to the ribosome, what happens to the first anticodon?
Answer:
The first anticodon leaves the ribosome through the E-site
Explanation:
Translation is the second stage of gene expression. It occurs in the ribosomes (organnelles of protein synthesis) where amino acid sequence is synthesized using a mRNA template. The tRNA (transfer RNA) is responsible for reading the mRNA codon using its ANTICODON, which is complementary to the mRNA codon.
The tRNA reads the mRNA codon and carries the amino acid that corresponds what it reads. tRNA has three binding sites on the ribosome; A-site, P-site and E-site. A tRNA molecule with the complementary anticodon binds to the codon on the P-site, and carries its corresponding amino acid. Another tRNA with complementary anticodon occupies the A-site, carrying the corresponding amino acid again.
Once both sites are occupied, the tRNA on the P-site transfers its amino acid to the one on the A-site to form a peptide bond. This causes the ribosome to shift the tRNA on the P-site, allowing the one on the A-site to be free. When this happens, the anticodon of the first tRNA on the P-site leaves the ribosome via the E-site in order to bind to another complementary mRNA codon and continue the translation process.

[tex] \frac{6x - 3}{2x + 7} = \frac{3x - 2}{x + 5} [/tex]
solve for x
urgent!!!!
will give the brainliest!!
Answer:
x = [tex]\frac{1}{10}[/tex]
Explanation:
In an equation our aim is to find the value of the whatever we are finding but in this case it is 'x' as well as keeping the equation balanced. If we did one operation on only one side then the equation has changed so it's important to remember that is you do an operation one side you must do it on the other otherwise the whole equation will change
[tex]\frac{6x-3}{2x+7} = \frac{3x-2}{x+5}[/tex]
→ First step is to cross multiply the denominators to get rid of the denominators so ( 6x - 3 ) × ( x + 5 ) and ( 3x - 2 ) × ( 2x + 7 )
( 6x - 3 ) ( x + 5 ) = ( 3x - 2 ) ( 2x + 7 )
→ Expand out the brackets using FOIL, first two, outer two, inner two and last two
6x² + 30x - 3x - 15 = 6x² + 21x - 4x - 14
→ Simplify and collect the 'x' terms together
6x² + 27x - 15 = 6x² + 17x - 14
→ Minus 6x² from both sides to isolate the whole numbers as well as the 'x' values
27x - 15 = 17x - 14
→ Minus 17x from both sides to collect the 'x' terms
10x - 15 = -14
→ Add - 15 to both sides to isolate 10
10x = 1
→ Divide both sides by 10 to isolate x
x = [tex]\frac{1}{10}[/tex]

Answer:
I doubt two different species of birds can live on the same tree
Explanation:
Because they don't do the same thing the same time so it would result to competition.
Two different species of birds living in the same habitat would be the same type of nesting place. As a result, both species will compete for the nesting sites.
Why species will compete?Because several species frequently coexist in the same areas and compete for the same resources, they engage in a range of interactions known as symbiosis.
Every living thing inhabits a certain ecosystem. Its natural environment is this ecosystem. Food, water, a refuge from the elements, and a location to produce young are all provided here in order for the organism to exist.
In places with adequate resources, creatures coexist peacefully, while in areas with plenty of resources, the ecosystem boasts a high species variety (diversity).
Therefore, the resources that organisms require to survive in air, water, food, and space are under competition.

Why is West Ferris not running out of water
Answer:
The population of East Ferris is increasing over time, while the amount of rainfall in East Ferris stays about the same over time. ... The population of East Ferris remains the same over time, while the amount of rainfall in East Ferris increases over time.
Explanation:
West Ferris is not running out of water as it rains more in West Ferris than in East Ferris.
• In the East Ferris, the population is increasing with time, while the amount of rainfall in East Ferris remains similar with time.
• Over the West Ferris the water vapor gets high up in comparison to the East Ferris. This makes water vapors to move to distinct parts of the atmosphere, and the mountains and winds direct the water vapors to the West Ferris.
• Due to the rain shadow effect, it rains more on the West Ferris. The sides of the mountains, which are hit more by wind exhibits more precipitation in comparison to the sides, which are not, this is known as the rain shadow effect.
• The wind seems to move from East to West, with the upward movement of the humid air, it gets cool and the condensation of water vapors takes place into clouds and falling of rain takes place.
Thus, due to continuous rain in the West Ferris it does not run out of water.
