Electromagnetic energy can be defined as: C. energy that moves as particles at the speed of light.
Electromagnetic energy can be defined as form of energy that is primarily carried by electromagnetic waves such as gamma rays and x-rays.
This ultimately implies that, electromagnetic energy refers to a form of energy that moves as particles at the speed of light, which is about three hundred million meters per seconds.

b. The undergrowth of rainforests is choked by weeds and plants.
c. Rainforests are characterized by high levels of rainfall.
d. Not all rainforests are tropical rainforests.
Rainforests are responsible for most global oxygen turnover is not true concerning the rainforests.
Further Explanation:
Rainforests are dense jungle and considerably tall. They are referred to as rainforest because every year, high rainfall occurs in these areas. The climate in these forests is very humid and hot, so the plant and animal exist in these areas and are adapted to this environment. The normal temperature of these areas is 70 degree Celcius – 85 degree Celcius-. Many household items are obtained from these forests. Most of South Africa and western Africa has the largest rainforest. In India and Australia, smaller rainforests are present.
Rainforest provides numerous benefits such as maintain the climate, greenhouse effect and provide space for animals and plants. Also, they produce food and medicine for many organisms. They are not responsible for providing global oxygen because plant present in humid areas takes a higher amount of oxygen to fee vegetation.

Rainforests have a unique ecological structure where the dense canopy of trees filters out much of the sunlight, leading to limited light penetration on the forest floor. The correct answer is b. The undergrowth of rainforests is choked by weeds and plants.
As a result, the undergrowth of rainforests typically has limited vegetation due to the lack of sufficient light, rather than being choked by weeds and plants. The majority of plant life and diversity in rainforests is concentrated in the upper layers of the forest, such as the canopy and understory.
Rainforests are characterized by a dense canopy formed by tall trees that grow close together and have large, spreading branches. These trees create a thick layer of foliage that blocks much of the sunlight from reaching the forest floor. Consequently, the amount of available light in the understory, the lower layer of the forest, is significantly reduced.
Therefore, the correct answer is b. The undergrowth of rainforests is choked by weeds and plants.

Answer:
The correct answer is option d. RNA polymerase binds to a promoter region of DNA
Explanation:
Hello!
We will answer that!
The process of transcription consists in the transformation of DNA into RNA from a DNA sequence.
At the beginning of the process the DNA opens in a promoter region and the RNA polymerase enzyme binds to begin transcription. The promoter region is a sequence of nucleotides in the DNA that indicate that the enzyme has to bind there.
So, the correct answer is option d. RNA polymerase binds to a promoter region of DNA
To complete our analysis we can say that the following options are arranged as follows:
c. Nucleotides are covalently linked together: all DNA nucleotides are linked with a covalent bond
b. RNA polymerase reaches a terminator region: when RNA polymerase reaches the terminator region, we have premature RNA
to. Introns are edited out of the premature RNA ..
Gene recombination is the most likely factor which can affect what color trait is selected for a particular environment. Genetic recombination is generally observed in sexual reproduction.
Gene recombination is a process of producing new combinations of the genetic material which occurs through alleles by the recombination of the DNA molecules in the nucleus. In this process, there is an exchange of genetic material that is DNA (deoxyribonucleic acid) between two different chromosomes or between different regions of the same chromosome in an organism.
Genetic recombination is important as it provides a constant DNA homogenization within a species and, therefore, species integrity as an elementary structure which is responsible for the preservation and rise in the level of ecological stability of the organisms in evolving lineages and increase in the survival rate of the organism.

B: rRNA genes
C: amino acid sequences of proteins
D: noncoding repetitive repeats and intron regions
E: specific proteins that are made by a cell under particular conditions
Answer:
E: specific proteins that are made by a cell under particular conditions
Explanation:
It is only specific proteins that are made by a cell under particular conditions can't be obtained from a genome sequence. In order to get information about this protein we need proteomics.
Genome sequence gives us an idea of nucleotide sequence of DNA and RNA molecules not proteins. Regulatory sequences such as promoters, enhancers, insulators, UTRs etc. all are a part of genome, rRNA genes are part of genome sequence too, non coding repetitive repeats and intron regions are also a part of genome sequence itself so option A, B & D are incorrect. Option C is also incorrect because amino acid sequence of proteins can also be determined by genome sequences because each nucleotide triplet which is known as codon refers to a specific amino acid. Option E is correct because by genome sequence we can easily get to know about amino acid sequence but not about specific protein which is synthesized at a particular condition.
