1)Sam needs 10 kg of lemons to make lemonade.If each of the bag weighs 1000 g how many bags does he need?

2)How many 250 g bags of grapes are needed to make 5 kg?

Answers

The answer to this question is 10
1) So he needs 10 kg, and we know that 1 bag is 1000g=1kg, so to get 10kg we do 1 x 10= 10 bags of lemons.
Sam needs 10 bags of lemons to make lemonade.

2)We know that 1 kg is 1000kg, and we want 5kg= 5000g, to see how many bags of 250g we need for it we do:
5000/250=20 bags.
20 bags are needed to make 5kg.

What is evolution ? In your own words.

Answers

The timely effects of natural selection. Otherwise known as the survival of the fittest. Evolution, from what I’ve learned, is the simple basis of an organism adapting in an environment and is shaped by it through time and evolution by natural selection.
Ok this is my opinion also I’m gonna give examples. So evolution is kinda like how they said we evolved from apes right? So if we evolved from apes think about how long it for them to finally transition into a human so that is how you can word it also transition. So I think the best way I can word evolution is something evolving from something else like a flower for example a flower first starts out as a seed and then it start’s growing/evolving into a flower. So basically how I would word it is something evolving into something! I hope this helped I know this isn’t a definition but a meaning of evolution have a great day!

Answers

Answer:

Tyr-stop codon-Gly-Leu-Ile (5'3' Frame)

Explanation:

Transcription is the process by which a specific fragment of DNA (i.e., a gene) is used as template to synthesize an RNA molecule, typically a messenger RNA (mRNA), which is then used as template to synthesize a protein in the ribosomes by a process called translation. During translation, each triplet of nucleotides (i.e., each codon) in the mRNA is read in order from the 5' end to the 3' end to add an amino acid to the nascent polypeptide chain. This 'genetic code' is not overlapping because each codon specifies one of 20 amino acid total possible and 3 stop codons (UAA, UAG, UGA). In this case, the second codon "TGA" in DNA or "UGA" in RNA (Uracil always replaces Adenine during transcription) is a stop codon that indicates the end of mRNA transcription.

_________.

Answers

Answer:

seperate

template

origin

During replication, the two DNA strands separates and each chain serves as a template for a new nucleotide chain. The sites where DNA replication and separation occur are called the origin.

What is DNA replication?

DNA replication defines the biological process of making two identical copies of DNA from a single original DNA molecule. It occurs in all living organisms which acts as the most essential part for biological heritage.

During DNA replication, each of the two strands forming the double helix serves as a template from which the new strand is copied, while these new strands will be complementary to the parental or "old" strand. Each new double strand consists of a parent strand and a new daughter strand.

Steps involved in the DNA replication are:

1. Initiation

2. Elongation

3. Termination

Thus, during replication, the two DNA strands separates and each chain serves as a template for a new nucleotide chain. The sites where DNA replication and separation occur are called the origin.
