Answer:

Oceans provide at least a sixth of the animal protein people eat. Living oceans absorb carbon dioxide from the atmosphere and reduce climate change impacts. The diversity and productivity of the world's oceans is a vital interest for humankind. Our security, our economy, our very survival all require healthy oceans.Many creatures depend and live in the Ocean.It is an important source of food.The Ocean regulates the Earth climate.The Ocean produces more oxygen than the Amazons.The Ocean has therapeutic properties.The Ocean is the heart of the planet. Water covers more than two-thirds of the Earth's surface.

Answer:

The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.

Answer: 1.) Protein: Met-Cys-Ala-Ser-His-Ala-Ile-Arg-Tyr

2.) Protein: Met-Glu-Asn-Cys-Ser-Gly-Arg-Glu-Ala-Thr

3.) Protein: Met-Glu-Pro-Leu-Ile-Cys-Ala-Thr-Glu-Ala-Thr

4.) protein: Met-Asp-Arg-Ile

5.) protein: Met-Ile-Ser-Leu-Ile-Phe-Glu

6.) protein: Met-Glu-Ser-Ile-Gly-Asn

7.) protein: Met-Glu-Arg-Ile-Ser

8.) Protein: Met-Ser-Ala-Val-Glu-Thr-His-Glu-Thr-Arg-Glu-Glu-Ser

Explanation: To produce a protein, genes from DNA have to be transcripted into RNA-messenger. In other words, in transcription the DNA is rewritten with the RNA nucleotides. So, in this sense, nucleotide A from DNA pairs with nucleotide U for RNA; nucleotide T pairs with nucleotide A; nucleotide C with G and nucleotide G with C.

From the DNA sequences given, we have the following RNAm:

1.) DNA: CCT CTT TAC ACA CGG AGG GTA CGC TAT TCT ATG ATT ACA CGG TTG CGA TCC ATA ATC

RNAm: GGA GAA AUG UGU GCC UCC CAU GCG AUA AGA UAC UAA UGU GCC AAC GCU AGG UAU UAG

2.) DNA: AGA ACA TAA TAC CTC TTA ACA CTC TAA AGA CCA GCA CTC CGA TGA ACT GGA GCA

RNAm: UCU UGU AUU AUG GAG AAU UGU GAG AUU UCU GGU CGU GAG GCU ACU UGA CCU CGU

3.) DNA: TAC CTT GGG GAA TAT ACA CGC TGG CTT CGA TGA ATC CGT ACG GTA CTC GCC ATC

RNAm: AUG GAA CCC CUU AUA UGU GCG ACC GAA GCU ACU UAG GCA UGC CAU GAG CGG UAG

4.) DNA: TAA ACT CGG TAC CTA GCT TAG ATC TAA TTA CCC ATC

RNAm: AUU UGA GCC AUG GAU CGA AUC UAG AUU AAU GGG UAG

5.) DNA: CTA TTA CGA TAC TAG AGC GAA TAG AAA CTT ATC ATC

RNAm: GAU AAU GCU AUG AUC UCG CUU AUC UUU GAA UAG UAG

6.) DNA: TAC CTT AGT TAT CCA TTG ACT CGA ATT GTG CGC TTG CTG ATC

RNAm: AUG GAA UCA AUA GGU AAC UGA GCU UAA CAC GCG AAC GAC UAG

7.) DNA: ACC CGA TAC CTC TCT TAT AGC ATT ACA AAC CTC CGA GCG

RNAm: UGG GCU AUG GAG AGA AUA UCG UAA UGU UUG GAG GCU CGC

8.) DNA: TAC AGA CGG CAA CTC TGG GTG CTT TGT TCT CTT CTC AGT ATC

RNAm: AUG UCU GCC GUU GAG ACC CAC GAA ACA AGA GAA GAG UCA UAG

With the RNAm, its sequence is translated into a sequence of aminoacids. This process happens by reading a group of 3 nucleotides, named codon. Each codon is specific for 1 aminoacids. The translation begins with codon AUG, which is the start codon and ends with another specific codon.

The correspondence of codon and specific aminoacids or stop signal is called genetic code and there is a table we can use to produce the sequence of aminoacids.

The translation process will be:

1.) RNAm: GGA GAA AUG UGU GCC UCC CAU GCG AUA AGA UAC UAA UGU GCC AAC GCU AGG UAU UAG

protein: Met-Cys-Ala-Ser-His-Ala-Ile-Arg-Tyr

2.) RNAm: UCU UGU AUU AUG GAG AAU UGU GAG AUU UCU GGU CGU GAG GCU ACU UGA CCU CGU

protein: Met-Glu-Asn-Cys-Ser-Gly-Arg-Glu-Ala-Thr

3.) RNAm: AUG GAA CCC CUU AUA UGU GCG ACC GAA GCU ACU UAG GCA UGC CAU GAG CGG UAG

protein: Met-Glu-Pro-Leu-Ile-Cys-Ala-Thr-Glu-Ala-Thr

4.) RNAm: AUU UGA GCC AUG GAU CGA AUC UAG AUU AAU GGG UAG

protein: Met-Asp-Arg-Ile

5.) RNAm: GAU AAU GCU AUG AUC UCG CUU AUC UUU GAA UAG UAG

protein: Met-Ile-Ser-Leu-Ile-Phe-Glu

6.) RNAm: AUG GAA UCA AUA GGU AAC UGA GCU UAA CAC GCG AAC GAC UAG

protein: Met-Glu-Ser-Ile-Gly-Asn

7.) RNAm: UGG GCU AUG GAG AGA AUA UCG UAA UGU UUG GAG GCU CGC

protein: Met-Glu-Arg-Ile-Ser

8.) RNAm: AUG UCU GCC GUU GAG ACC CAC GAA ACA AGA GAA GAG UCA UAG

protein: Met-Ser-Ala-Val-Glu-Thr-His-Glu-Thr-Arg-Glu-Glu-Ser

A forest fire in Florida clears thousands of acres of trees. What are the consequences for the animal populations in the surroun

nekit [7.7K]

The correct answer is (c) The animal populations will increase in the surrounding forests.

The forest provides shelter for the animals. If there is forest fire in Florida and it clears thousands of acres of trees then the population of the surrounding forest will increase. As a result of forest fire the population living there will run to some another nearby place and the surrounding forest will serve as shelter for the those animals. The forest nearby will also provide food which is also an essential part for the survival of animals.

Thus, the population of surrounding forest will increase.

Drag each label to the correct location on the image.

ratelena [41]

Answer:

The offsprings of this punnet square will be Dd, Dd, dd and dd in a ratio 1Dd : 1dd

See attached image for punnet square completion

Explanation:

This question involves a cross involving a single gene with alleles D and d where allele D is dominant over allele d i.e. D will mask the phenotypic expression of d in a heterozygous state.

This cross is between a heterozygous parent (Dd) and a homozygous recessive parent (dd). Parent Dd will produce gametes D and d while parent dd will produce gametes d and d.

Using these gametes in a punnet square, four possible offsprings with two distinct genotypes will be produced. The genotypes are: Dd and dd in a ratio 1:1

Hence, the possibility of having a heterozygous dominant offspring is 1/2 while the possibility of having a homozygous recessive offspring is also 1/2.
