Answer:
fibras nerviosas
Explanation:
Los nervios están compuestos por grupos de fibras nerviosas las cuales consisten de axones y las vainas que los recubren. Una fibra nerviosa está generalmente compuesta por 1-un cilindroeje (axón), es decir, una prolongación alargada de la neurona la cual conduce el impulso nervioso (señal eléctrica), 2-el axolema, o membrana celular del axón, 3-la vaina de mielina que rodea el axón y 4-el neurilema que rodea la fibra. Las fibras nerviosas se clasifican en 1-fibras mielínicas, cubiertas por la vaina de mielina, y 2-fibras amielínicas, no recubiertas por esta vaina. La presencia de la vaina y el diámetro de la fibra influyen en la velocidad de transmisión del impulso eléctrico a través de la fibra nerviosa.

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.
Question 5 (5 points) (04.03 MC) A student made the following diagram to represent cellular respiration. Why is this diagram incorrect?
A.water is not used up during this process.
B.glucose is not used up during this process.
C. The arrow for oxygen should point in the opposite direction.
D. the arrow for carbon dioxide should point in the opposite direction.
Answer:
A
Explanation:
The chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O (+ ATP)OR: Glucose + Oxygen → Carbon Dioxide + Water (+ Energy)
Since water is on the right side of this equation, it is produced as a result of the metabolic process rather than used up. So, the correct is A.

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)

what is chemical weathering? what are some facts?
Answer:
Chemical weathering is the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
Explanation:
1. There are four types of chemical weathering: Reaction with water, Reaction with acid, Reaction with oxygen, and Reaction with organisms.
2. Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals.

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.

Describe the Lytic cycle.
No dam links
Answer:
Ok here ya go
Explanation:
The lytic cycle is one of the two cycles of viral reproduction, the other being the lysogenic cycle. The lytic cycle results in the destruction of the infected cell and its membrane. Now during the lytic cycle of virulent phage, the bacteriophage takes over the cell, reproduces new phages, and destroys the cell. T-even phage is a good example of a well-characterized class of virulent phages.

Pollen and Ovules are gametes. How many chromosomes would they have compared to the rest of the plant's body cells? What process made them that way?
Answer:
a. They would have half chromosomes as much as the plants body cells.
b. Meiosis
Explanation:
Gametes are sex cells produced only in sexually reproducing organisms. In plants as stated in this question, male gametes are contained in pollens while female gametes are contained in ovules. The process by which these gametes are made is called MEIOSIS.
Meiosis is a cell division that reduces the chromosomal number of the parent cell by half. This means that each GAMETE will contain half the number of chromosomes as the parent cell. Fir example, if the body cell of a plant contains 30 chromosomes, each gamete formed via Meiosis in that plant will have 15 chromosomes.
In a nutshell, pollen and ovules, which are gametes of plants formed by MEIOSIS would have half chromosomes as much as the plants body cells.
