Answer:
A. DNA
Explanation:
Nucleus. The nucleus, a substantial organelle that houses the cell's DNA, is referred to as the “command center” of the cell (deoxyribonucleic acid). Thus, option A is correct.
What is the main function of DNA?
The genetic information contained in the DNA is used by the nucleus to regulate all cellular functions, including growth and metabolism.
Today, DNA has three separate purposes: genetic, immunological, and structural, all of which differ greatly from one another and depend in different ways on the bases and the sugar phosphate backbone.
Genetic information is encoded in the nucleotide order along the backbone. Replication, information encoding, mutation/recombination, and gene expression are the four functions that DNA performs.
Therefore, DNA which is found in nucleus control a cellular activity.

Why is adequate lighting necessary in a balanced aquarium?
a. Fish need light to see their food.
b. Fish take in oxygen in the dark.
c. Plants expel carbon dioxide in the dark
d. Plants grow too rapidly in the dark.
Answer:
A. Fish need light to see their food
Explanation:
B is incorrect because fish take in oxygen constantly to respirate. If they only took in oxygen when it was dark they would die.
C is incorrect because expelling CO2 is also a constant process as a part of the reactions that take part inside living organisms, so it happens constantly (a bit like B)
D is incorrect because plants need light for food (photosynthesis) and would most likely die or have stunted growth if left in the dark.
A is correct because when it is dark, fish rely on other senses to find food as most fish cannot see as well in the dark, therefore when they have light they can see their food more easily.

Which of the following best compares Linnaeus's classification system to the classification system developed by Carl Woese and his colleagues in the 1990s?
Linnaean taxonomy classifies organisms into kingdoms based on physical traits, while Woese's classification sorts organisms into domains based on genetic differences.
Linnaean taxonomy classifies organisms into domains based on complexity, while Woese's classification sorts organisms into kingdoms based on method of obtaining nutrients.
Linnaean taxonomy classifies organisms into realms based on geographic location, while Woese's classification sorts organisms into domains based on method of reproduction.
Linnaean taxonomy classifies organisms into taxa based on size, while Woese's classification sorts organisms into kingdoms based on physical traits.
Answer:
The correct answer is - Linnaean taxonomy classifies organisms into kingdoms based on physical traits, while Woese's classification sorts organisms into domains based on genetic differences.
Explanation:
Linnaean classification is set up by Carl Linnaeus which is used to divide and organized organisms into different groups according to some similar basic features such as physical traits. It was the most basic type of classification.
The classification of Carl Woese was based on the different genetic differences to categorize or group organisms. This was a three-domain system that includes Bacteria, archaea, and eukarya.
Answer:
Linnaean taxonomy classifies organisms into kingdoms based on physical traits, while Woese's classification sorts organisms into domains based on genetic differences.

A cellular biologist is curious as to why a protein is not being expressed even though they placed the needed transcription factors and ribosomes allowing for the transcription and translation of the protein to take place in the cell. They look at the mRNA and find it is being translated and exported to the nucleus but ribosomes are not binding to it. After careful observation she finds out that the mRNA is missing its _____________. Without this of course ribosomes would have an issue binding to the mRNA and inducing translation.
Answer:
5' cap
Explanation:
In eukaryotes, the 5′ end of mRNA in eukaryotes is modified (i.e., capped) with a guanine nucleotide which is connected to mRNA via 5´→ 5´ triphosphate linkage. The five-prime cap (5′ cap) is denoted as 7-methylguanylate cap (m7G) because guanosine is methylated at the 7 position by a 7-methyl transferase. This cap acts to protect the mRNA from degradation and also is required during translation initiation in order to mediate a process known as ribosome recruitment. This process (ribosome recruitment) occurs through the association of the 43S preinitiation complex (composed of the small ribosomal subunit, eIF1, eIF1A, eIF2, eIF3 and eIF5 factors) with the 5' capped mRNA. After mRNA binding, the 43S preinitiation complex is ready to scan an initiation codon in order to start the translation.
Identify structure B in Figure 12-5:
A) aRNA
B) mRNA
C) rRNA
D) tRNA
I need help please
Answer:
B
Explanation:
mRNA is the messenger RNA that exits the nucleus and moves over to the ribosome, but it doesn't go in, tRNA goes in, figure G is tRNA.
Structure B given in the diagram is mRNA which is released out of the nucleus to undergo translation for the synthesis of proteins. So option B is correct.
What is the role of mRNA in protein synthesis?The mRNA carries the genetic information of an individual from the nucleus of the cell to the cytoplasm. The information encoded in the DNA is first transcribed into mRNA and the mRNA is then transported into the cytoplasm for translation.
The process of translation is aided by the protein factories of the cell which are the ribosomes. The ribosomes bind onto the mRNA and start the process of synthesis with the help of the initiator tRNA and further elongate the chain of amino acids to synthesize a complete polypeptide. There are two different types of ribosomes present in the prokaryotic and eukaryotic cells to carry out translation.

Answer:
Please find the mRNA and amino acid of the DNA sequence in the table below.
Explanation:
This question is describing the processes of transcription and translation. Transcription is the synthesis of mRNA from a DNA template while translation is the synthesis of an amino acid sequence from a mRNA sequence.
The following nucleotides combination are given in this question. Their transcription into mRNA using the complementary base pairing rule is as follows;
DNA = mRNA
- ATG = UAC
- GTA = CAU
- CAA = GUU
- AAT = UUA
- GCG = CGC
- TGT = ACA
- ACT = UGA
- CCC = GGG
- TAG = AUC
Using the codon chart attached as an image, the translation of these mRNA codons is as follows:
mRNA = amino acid
- UAC = tyrosine (tyr)
- CAU = histidine (his)
- GUU = Valine (Val)
- UUA = Leucine (leu)
- CGC = Arginine (Arg)
- ACA = threonine (Thr)
- UGA = STOP codon
- GGG = Valine (Val)
- AUC = Isoleucine (Iso)

A K-selected species will exhibit which of
the following characteristics?
A. wildly fluctuating population size
B. generalized niche
C. early reproductive age
D. low population growth rate
Answer:
it's D
Explanation:
This is because K-selected species produce fewer offspring in their life time compared to R-selected species therefore their growth rate is lower.
The option or characteristic that will be exhibited by K-selected species is that it has a low population growth rate. Thus, the correct option for this question is D.
What is a K-selected species?A K-selected species may be defined as a more or less stable population adapted to exist at or near the carrying capacity. These types of species have specialized niches along with a logistic growth model.
The reproductive rate of these species is low as compared to r-selected species. Reproductive age is late. They have a fairly strong competitive ability due to which they show very less fluctuation in population size. Examples of these species may include canopy trees, large mammals, large turtles, some parrots, etc.
Therefore, the option or characteristic that will be exhibited by K-selected species is that it has a low population growth rate. Thus, the correct option for this question is D.

The 5' cap is a modified cytosine nucleotide and the 3' polyA tail is comprised of 50-250 alanine residues. The purpose is to stabilize the mRNA. d. The mature messenger RNA is translated by the ribosome in the cytoplasm. The ribosome reads the mRNA in a 5' -->3' direction while synthesizing protein in a N-->C direction e. multiple of the options are true
