Answer:
To find out the impact of environment on the physical structure of lizard and natural selection.
Explanation:
Ecologists conduct an investigation on the survival of a species of lizards in order to study the impact of environment on the physical body of lizard and natural selection. The ecologists find out that environment has direct impact on the body structure of lizard. Those lizards that spend more time on the ground, have longer legs in order to run fast, while on the other hand, species that lives in the trees usually have shorter legs in order to easily climb on the trees so these body structure helps them in survival and movement.

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.

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.

Answer:
B
Explanation:
C table correctly lists the characteristics of the organisms in the two kingdoms. So, the correct option is C.
What is Five kingdom classification?The system of biological kingdoms is the way in which science classifies living things in order of evolution according to their ancestors which means all species that make up these five large groups. Some recent theories divide them further into six or seven showing the common ancestors and sharing some of their genes which belong to the same family tree.
Along with the kingdoms of living things, there are other taxonomic categories within the same classification system, such as, for example, domain, kingdom, phylum, class, order, family, genus, and species.
Therefore, the correct option is C.

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.

In regards to the Central Dogma... Select one: a. Transcription involves RNA polymerase which is recruited to origins of replication by transcription factors b. Eukaryotic mature messenger RNA, exported from the nucleus to cytoplasm, has been spliced and modified at the 5' and 3' end. c. 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
Answer:e. multiple of the options are true
Explanation:
DNA central dogman involves DNA replication, DNA transcription and DNA translation which involves the formation of protein.
Replicated DNA are transcribed to an intermediary mRNA(Messenger ribonucleic acid) from where it is moved from the nucleus to ribosome in the cytoplasm. Enzyme RNA polymerase helps in proof reading ,replication and transcription of bases during transcription. translation takes place in the ribosome with the help of ribosome in the presence of enzyme tRNA (transferase ribonucleic acid) that reads the codon and brings corresponding amino acid which are functional protein.

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.
Hope this helped!
