Gwar [14]

Answer: B. False

Explanation:

“Hox” genes are a highly conserved group of genes, all of whose products are transcription factors bearing a specific domain (called a ”homeodomain”). The transcriptional activity of a large amount of genes relevant to embryonic development is controlled by regulatory sites which are able to bind to this domain. Changes in the transcriptional activity of even a single Hox gene may thus have dramatic downstream effects on the phenotype, as this will result in several further genes having their transcription either enhanced or suppressed.

Describe some of the ways in which real-world pateontology is different from how it is presented in movies
garik1379 [7]

Answer:

Paleontology in the real world isn't as careless and usually in movies they mis-label things. Paleontology isn't as simple as it seems and in many movies they portray little effort or processing and handling of the fossils. It requires much attention and you have to take care of the bones. Jurassic Park is a great example of fake paleontology and comparing it to real paleontology can surprise you.

saw5 [17]

Ans. (4). protein synthesis.

Protein synthesis can be defined as a process that involves formation of polypeptides or proteins by using information present in DNA. It is divided into two steps, transcription and translation.

During transcription, DNA is transcribed into mRNA and information present in DNA is transferred to mRNA as codons. Codons represent triplet of nucleotides and each codon codes for a specific codon.

Translation involves formation of protein, during which amino acids are added to the growing polypeptide chain with the help of codons.

The given diagram represents process of translation. Thus, the correct answer is option (4).

Which organism created all usable food energy on Earth​
Zigmanuir [339]

Answer:

The Sun

Explanation:

The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
