What happens at a cell cycle checkpoint?
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA. If the damage is irreparable, the cell may undergo apoptosis, or programmed cell death 2.

Test One: If I breed a short fur, FF female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Since all these offspring only have one trait for long fur, this trait stays hidden in their DNA and is not expressed in their phenotype. All the offspring will have short fur.
Test Two: If I breed a short fur, Ff female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Test Three: If I breed a long fur, ff female with a long fur, ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Answer:
test two:
some short fur and some long fur will be seen.
this is because in some cases, the offsprings have only have the trait for short fur or just one trait for long fur and so short fur is expressed in the phenotype. in other cases, the offsprings have only the trait for long fur and so long fur is expressed phenotypically.
test three:
all long fur is seen.
since all the offsprings only have the trait for long fur and no trait for short fur, long fur is expressed in the phenotype.
Assuming a diallelic gene coding for the trait and expressing complete dominance, 1) all short fur. 2)some short and some long fur. 3) all long fur.
According to the information that was provided, we can assume that the trait fur length is coded by a single diallelic gene
• dominant allele F codes for short fur
• recessive allele f codes for long fur
We can also assume that the gene expresses complete dominance.
What is complete dominance?It is the inheritance pattern in which the dominant allele completely masks the recessive allele.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant phenotype. The dominant allele is hiding the expression of the recessive allele.
Many genes show complete dominance.

Parentals) FF x Ff
F1) 100% short fur
All short fur
Cross 2:
Parentals) Ff x Ff
F1) 1/4 FF + 1/2 Ff / 1/4 ff

El sistema nerviosos esta formado por un conjunto de fibras acordonadas, largas y delgadas, a estas se les denomina.
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.
Number the steps from when a stimulus is received to when the body reacts.
_____ The stimulus is received by sensory receptors.
_____ Motor neurons cause muscles to contract so the body can react to the stimulus.
_____ The brain processes the information through interneurons.
_____ Interneurons transfer response information to motor neurons.
_____ Sensory neurons carry stimulus information to the brain or spinal cord.
Answer:
The correct answer is -
1 - The stimulus is received by sensory receptors.
2 - Sensory neurons carry stimulus information to the brain or spinal cord.
3 - The brain processes the information through interneurons.
4 - Interneurons transfer response information to motor neurons.
5 - Motor neurons cause muscles to contract so the body can react to the stimulus.
Explanation:
In most of the organism including humans body response according to the stimulus it receives. The stimulus is received by the sensory receptors to the sensory neurons or afferent neurons that are present on the skin, nose tongue ears, or eyes. Many other receptors and pain receptors present on various internal organs as well.
These sensory neurons carry the stimulus to the spinal cord or brain where this information received by the stimulus process through interneurons and transfer the response of the particular stimulus to the motor neurons. These motor neurons result in muscles contracts so the body can react.
The different forms of the beef cattle color gene are called_
The different forms of the beef cattle color gene are called "alleles"
What are alleles?Alleles are alternative versions of a gene that arise from mutations and are located at the same position on a chromosome.
In the case of beef cattle, the color of the animal is determined by the interaction of multiple genes, including the color gene. The color gene can have different alleles that influence the color of the animal's coat. For example, one allele may result in a black coat color, while another allele may result in a red coat color.
The combination of alleles that an animal inherits from its parents determines its genotype, which in turn determines its phenotype or observed traits. Therefore, the different alleles of the beef cattle color gene can result in different coat colors, patterns, and markings in the cattle population.

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.

Lodgepole pine trees produce seeds in cones. The cones open after being exposed to high temperatures created by wildfires. How does this adaptation help the lodgepole pine survive?
A) It allows the lodgepole pine tree to make more seeds in cones that are hard to open.
B) It creates more wildfires for the lodgepole pine tree to reproduce.
C) It makes the seeds travel and grow in areas where there are no wildfires.
D) It helps the lodgepole pine tree to protect the seeds and to reproduce.
Answer:
D
Explanation:
A layer of resin and woody tissue sticks the cones' scales together. The seeds are locked in tight, and the cones can't open unless they're exposed to VERY high temperatures like the type of temperatures that fire provides. This shows they survive through exposing the seeds after forest fires.
Answer:
D
Explanation:
A It allows the lodgepole pine tree to make more seeds in cones that are hard to open. IS WRONG B) It creates more wildfires for the lodgepole pine tree to reproduce. IS WRONG C) It makes the seeds travel and grow in areas where there are no wildfires. DEFINITLY NOT so that leaves it with D It helps the lodgepole pine tree to protect the seeds and to reproduce.

Please help due tomorrow
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)
