Answer:
corrugated cardboard tube - digestive tract
irregular surfaces on the corrugated tube - villi
pump - heart
Plastic tubing - blood vessels
Explanation:
The corrugated cardboard tube represents the digestive tract. The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.
Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.
The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.
The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body

in the fruit fly, the long wing allele is dominant over the short wing allele. What are the parental genotypes for a cross that yields 75% long winged offspring and 25% short winged offspring.
Answers
According to the scenario, the parental genotypes for a cross that yields 75% long-winged offspring and 25% short-winged offspring are Ll and Ll.
What are Genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are significantly taken for specific studies.
According to the context of this question, in the fruit fly, the long-wing allele is dominant over the short-wing allele. This means that capital L is dominant over small l. So, the genotypes LL and Ll govern the dominant trait, i.e. Longwing.
The Punnett square for the given cross is as follows:
Therefore, the parental genotypes for a cross that yields 75% long-winged offspring and 25% short-winged offspring are Ll and Ll.

1. The wings are missing in mutant fly L, which is likely the result of a mutation in________ .
2. Mutant fly X has lost the head and thorax. The gene most likely responsible for this mutation is____________.
3. Thoracic and abdominal structures are missing in mutant fly Q. The gene most likely responsible for this mutation is__________ .
4. Mutant fly F has predominantly lost abdominal structures, which is likely the result of a mutation in _________ .
5. The mutation observed in mutant fly O resulted in defects within the anterior or posterior regions of each segment. The gene that most likely caused this mutation is _________.
6. Segment-sized sections of every other segment are missing in mutant fly Z. One likely candidate gene is ________
a. hunchback (a gap gene)
b. even-skipped (a pair-rule gene)
c. wingless (a segment-polarity gene)
d. knirps (a gap gene)
e. hedgehog (a segment-polarity gene)
f. Kruppel (a gap gene)
Answers
Answer:
1.wingless (a segment-polarity gene)
2. hunchback (a gap gene)
3. Kruppel (a gap gene)
4. knirps (a gap gene)
5. hedgehog (a segment-polarity gene)
6. even-skipped (a pair-rule gene)
Explanation:
The gap genes are genes expressed during embryonic development of some arthropods. Loss of function mutations of the gap genes are responsible to produce structural "gaps" in the corresponding region of the embryo. The gap genes are transcription factors that modulate the expression of pair-rule genes, which in turn are required for embryonic development of the alternate segments. On the other hand, the segment polarity genes are involved in determining the anterior/posterior axis of each segment (the segment polarity network). In the embryo, segment-polarity genes are expressed at specific localizations only after the expression of gap and pair-rule genes.

Which of the following correctly describes the process of Translation?
I. tRNA anticodon bonds to mRNA codon
II. Ribosome bonds to mRNA strand
III. Ribosome reaches a STOP codon and detaches from the mRNA
IV. Each tRNA adds an Amino Acid to the chain as the Ribosome moves along the mRNA
V. Complimentary mRNA strand is made from DNA template
Answers
Answer:
I. tRNA anticodon bonds to mRNA codon
II. Ribosome bonds to mRNA strand
III. Ribosome reaches a STOP codon and detaches from the mRNA
IV. Each tRNA adds an Amino Acid to the chain as the Ribosome moves along the mRNA
Explanation:
Translation is the second process of gene expression in which a protein molecule is synthesized from the information in a mRNA strand. Translation occurs in the RIBOSOME (an organnelle for protein synthesis made up of ribosomal RNA (rRNA) and proteins). The process of translation occurs in three stages viz: Initiation, Elongation and Termination.
Initiation occurs when the ribosome binds to the mRNA strand in the cytoplasm. The mRNA sequence is then read in a group of three nucleotides called CODON by the ANTICODON of a transfer RNA (tRNA). The basis of reading is the complementary base pairing rule i.e. A-U, G-C. Options I and II describes this stage.
In the elongation stage, the tRNA carries an amino acid corresponding to what it reads in the mRNA codon to the growing polypeptide chain. The amino acids bonds to one another via a peptide bond. As each codon is being read, the mRNA gradually moves over the means sequence. Option IV describes this stage.
Elongation stage continues until any of the stop codons (UAA, UAG, and UGA) are finally encountered by the trans in the ribosome. Since, there are no corresponding anticodons that can read the stop codons, they signal the termination of the translation process. The ribosome then detaches from the mRNA sequence. Option III describes this stage.
Note, option V describes TRANSCRIPTION not TRANSLATION.

A) cerebral cortex.
B) basal nuclei.
C) sensory pathways.
D) motor pathways.
E) All of the answers are correct.
The correct answer is E.
Explanation:
The cerebral cortex processes and filters its information before passing the most relevant aspects to other regions of the brain. Some of these brain regions, in turn, send information back to the cortex. These loops, known as 'feedback systems', are considered essential for the functioning of cortical networks and their adaptation to new sensory information. Neural circuits must first assess the importance of incoming sensory information and then refine how it is processed in the future. Positive feedback, triggered with the purpose of amplifying the response to the initial stimulus, can be compared to a chain reaction or a vicious circle. Few are the functions regulated by this mechanism; rather it is triggered in pathological situations. It is the system by means of which the organism very rarely regulates any of the bodily functions under normal conditions, making the initial stimulus to be maintained and even increased. This type of mechanism is predominantly present in pathological situations: Its constitutive elements are: stimulus, receptor, afferent pathway, integrating center, efferent pathway, effector and response. The response does not have the ability to satisfy the initial stimulus.

Answers
Answer:
Panda and polar bear have some similar characteristics but they also have differences in their behaviors such as polar bears have high daily energy expenditure and are very active while pandas are not.
The panda and polar bear so different because of the geographical difference where they live.
Polar bears are marine mammals and live in north pole perform swimming in north oceans and also move on ice flows, where they catch seals for survival, it makes them active and energetic.
While Pandas are found in China bamboo forests and are herbivores. They eat leaves from bamboo trees, for which they do not require to be more active and get their food easily. So, Pandas are not active as polar bears.
As the climate of North pole and China is cold, both polar bear and panda have very good insulation
