b. a limiting factor

An early winter frost that stops a tomato garden's growth is an example of a limiting factor, hence option B is correct.

Anything that limits the size of a population and slows or prevents its growth is referred to as a limiting factor.

Biologic factors including food, mates, and competition with other species for resources are some examples of limiting constraints.

the element that restricts the rate of reaction in any physiological process with lots of variables. the environmental component that has the greatest influence on population size restrictions. Many deer populations are constrained by a shortage of winter forage.

Therefore, winter frost that stops a tomato garden's growth is an example of a limiting factor, hence option B is correct.

Explanation:

Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteinsThe main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand.Transcription of a gene takes place in three stages: initiation, elongation, and termination. Here, we will briefly see how these steps happen in bacteria. You can learn more about the details of each stage (and about how eukaryotic transcription is different) in the stages of transcription article.

Initiation. RNA polymerase binds to a sequence of DNA called the promoter, found near the beginning of a gene. Each gene (or group of co-transcribed genes, in bacteria) has its own promoter. Once bound, RNA polymerase separates the DNA strands, providing the single-stranded template needed for transcription.Elongation. One strand of DNA, the template strand, acts as a template for RNA polymerase. As it "reads" this template one base at a time, the polymerase builds an RNA molecule out of complementary nucleotides, making a chain that grows from 5' to 3'. The RNA transcript carries the same information as the non-template (coding) strand of DNA, but it contains the base uracil (U) instead of thymine (T). [What do 5' and 3' mean?]Termination. Sequences called terminators signal that the RNA transcript is complete. Once they are transcribed, they cause the transcript to be released from the RNA polymerase. An example of a termination mechanism involving formation of a hairpin in the RNA is shown belowIn bacteria, RNA transcripts can act as messenger RNAs (mRNAs) right away. In eukaryotes, the transcript of a protein-coding gene is called a pre-mRNA and must go through extra processing before it can direct translation.

Eukaryotic pre-mRNAs must have their ends modified, by addition of a 5' cap (at the beginning) and 3' poly-A tail (at the end).

Many eukaryotic pre-mRNAs undergo splicing. In this process, parts of the pre-mRNA (called introns) are chopped out, and the remaining pieces (called exons) are stuck back together.

End modifications increase the stability of the mRNA, while splicing gives the mRNA its correct sequence. (If the introns are not removed, they'll be translated along with the exons, producing a "gibberish" polypeptide.)

Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes.

Transcription occurs in three steps—initiation, elongation, and termination.

Eukaryotic cells contain three distinct nuclear RNA polymerases that transcribe distinct classes of genes.

Protein-coding genes are transcribed by RNA polymerase II to yield mRNAs, ribosomal RNAs (rRNAs) and transfer RNAs (tRNAs) are transcribed by RNA polymerases I and III.

Thus, this is the summary of the transcription.

The direct result of an error in the transcription of a DNA nucleotide is that a codon sequence will be incorrect. So the correct option is C.

The first step in the expression of a genetic code is called transcription. During gene expression, the information stored in the DNA is expressed in the form of proteins.

In transcription, DNA is utilized to produce RNA. The RNA molecule is the copy of the DNA's genetic sequence. The RNA copy produced by the process of transcription is called an RNA transcript.

This transcript has the required information for the construction of a polypeptide chain. But before the formation of proteins, a eukaryotic RNA transcript requires processing to be converted into mRNA.

The mRNA thus produced has codons for the formation of proteins. Each amino acid is a result of the translation of three codons.

Therefore, if there is an error in the transcription of DNA nucleotides, the codon sequence will be incorrect. The correct option is C.

Answer:

habitat destruction

Explanation:

A forest ecosystem offers a variety of ecosystem services and functions. Prominent among the services offered include habitats to a variety of fauna, watershed protection, carbon sequestration, etc.

When the trees in a forest are removed by clear-cutting, some of the services and functions specific to the tree layers cease. The various habitats provided are destroyed and the organisms that live in these habitats disappear.

Hence, if a forest ecosystem is removed through clear-cutting, many species of organisms that lived in that ecosystem disappear. Their loss is due to habitat destruction.

Explanation:

Goofy is blocking the way with 15 N force and Donald was only able to knock Goofy off using a 20 N force. The net force would be the difference between the applied force of Donald and that of Goofy.

Hence,

      20 N - 15 N = 5 N

The net force is, therefore, 5 N.

Reducing the use of fossil fuels since they emit CO2 that reacts in water

CO2+H2O-->H2CO3

The following would most improve the health of coral reefs is reducing the use of fossil fuels.

One of the biggest threats to coral reefs is the so-called "coral bleaching", a process that leads to the death of hundreds of corals around the world. The phenomenon occurs when the temperature of the water increases, due to natural causes, such as El Niño, or caused by man, such as global warming.

Scientists have created a device that innovates the technique of transplanting corals from the recovery of fragments with tissue loss. The device works as a kind of cradle, where the fragments are kept until they recover and grow.

Answer:

Sexual reproduction.

Explanation:

Sexual type of reproduction used by the marine biologist in order to develop the new coral because variations in an organisms only be done with sexual reproduction. For producing new type of coral, the type of corals should be fused together in order to gain the desire characters in the organisms. So if the marine biologist want coral polyps with large stinging tentacles, sexual reproduction is the only way. From asexual reproduction, the offspring produce identical to parents so that's why we can't use asexual reproduction.
