2.Write two differences between the nutrition in amoeba and human beings.
3.Fungus can be harmful and useful. Give an example showing both of these traits of fungus.
Answer:
Similarity:
Amoeba and human beings require the same nutrients like carbohydrates, proteins, and fats for their growth and survival.
Difference:
1. Mode of Nutrition:
Amoeba is unicellular and microscopic, which makes it an organism that uses the Holozoic mode of nutrition. It ingests food through its cell membrane and feeds on other tiny organisms like bacteria, algae, and protozoans. On the other hand, human beings are multicellular organisms and use saprophytic and holozoic modes of nutrition. They ingest complex food materials that are broken down into simpler nutrients.

Fred loves La Paz, Bolivia so much that he decides to stay there for a couple years. All of the following changes could be considered a compensatory mechanism in response to the chronically decreased oxygen content EXCEPT
a. an increase in amount of circulating red blood cells.
b. an increase in oxygen extraction by perfused cells.
c. an increase in hemoglobin’s affinity for oxygen.
d. a decrease in heart rate.
Answer:
d. a decrease in heart rate.
Explanation:
As the altitude rises, the number of oxygen molecules in the air decreases. Lower oxygen levels at high altitudes stimulate the release of erythropoietin (EPO), which is associated with the increased red blood cells, i.e., it enables more oxygen molecules to be transported to cells and tissues. Moreover, at high latitudes, the increased hemoglobin (Hb)–oxygen affinity helps to safeguard arterial O2 saturation and thus mitigates the effects of low oxygen concentration in arterial blood (arterial hypoxemia). Finally, oxygen extraction depends on an appropriate supply of oxygen in the blood vessels. An increased oxygen extraction occurs when there is an inadequate circulating blood volume or when the number of red blood cells decreases below the normal levels.
Whose argument is stronger regarding the SAC curves and the LAC curve? A. The draftsman since the lowest point on each SAC curve will have a horizontal tangent line which only occurs at the lowest point on the LAC. B. Jacob Viner since the SAC curves can be adjusted slightly and still keep their U-shape in a way that makes their lowest points end up on the LAC curve. C. Jacob Viner since the long-run average cost curve must be composed of the lowest points on any individual short-run average cost curve. D. The draftsman since, while it is true that the points of tangency of the SAC curves with the LAC curve are at each SAC curve's minimum, it is impossible to illustrate it accurately.
NB: This is a business question, not biology.
Answer:
SAC (Short-run Average Cost) and LAC (Long-run Average Cost)
The stronger argument regarding the SAC (Short-run Average Cost) curves and the LAC (Long-run Average Cost) curves is:
A. The draftsman since the lowest point on each SAC curve will have a horizontal tangent line which only occurs at the lowest point on the LAC.
Explanation:
The costs of all factors of production become variable in the long run. But in the short-run, some costs are variable, and some are fixed. When the producer starts operating over the long run period, it can then operate without the constraints imposed by the presence of the fixed-cost factors. Therefore, in the long run, the average cost (LAC) is equal to the short-run average cost (SAC) because there is an unconstrained minimum average cost at all output levels.

Prelab Information
Purpose Explore the molecular process of building proteins from the information carried by RNA
using a laboratory procedure.
Time Approximately 45 minutes
Question How are proteins built using the information provided by a molecule of RNA?
Prediction RNA determines the sequence of amino acids in proteins and polypeptides by a two-step process: transcription of DNA produces mRNA in the nucleus, then translation
of the mRNA to tRNA takes place at the ribosome in the cytoplasm.
Answer and Explanation:
Proteins are built using information from RNA, because proteins are made up of amino acids that are arranged in a specific sequence for each protein. This amino acid sequence is determined by RNA, which forms groups of three consecutive nucleotides, which will signal the position that each amino acid must assume to form a protein.
In summary, we can state that the DNA starts the transcription process to create the mRNA, which will have the nucleotides transported by the tRNA from the nucleus to the cell's ribosome, so that there, the nucleotides are organized in a specific sequence, forming amino acids, which will constitute the protein.

What is DNA?
DNA is defined as deoxyribonuclic acid and it is a polymer made up of two polynucleotide chains that arranged in foiled structure to form a double helical carrying genetic information for the various processes such as growth development functioning and reproduction.
There are four nitrogen bases of DNA nucleotides are such as adenine, thymine, guanine and cytosine. Friedrich Miescher discovered DNA in the year of 1860.
The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.
In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA. The shape of DNA is double helical structure. Siblings share only about 50% of same DNA due to the reason of recombination.The life span of DNA is 521 years.
Therefore, the term for DNA bound to proteins that floats loosely in the nucleus is chromatin. Thus, option D is correct.

What is the relationship between types of kinetic chain and whether the origin moves toward the insertion or the insertion moves toward the origin during a muscle contraction?
____________________________________
____________________________________
____________________________________
The Kinetic Chain is an engineering concept used to describe human movement. It is used in a wide variety of clinical condition including musculoskeletal, sports medicine, neuro rehabilitation, prosthetic and orthotics.
The concept of Kinetic Chain was introduced by Franz Reuleaux in 1875. According to him overlapping segments were connected via joints and this created a system where movement ay one joint produced or affected movement at another joint in the kinetic link.
Two types of Kinetic Chain are:
Open Chain:
It is a combination of successively arranged joints in which terminal segment can move freely. Thus the distal segment of the extremity is free to move in space, example- Waving a hand
Characteristics:
- Characterized by a rotary stress pattern at the joint.
- Occur in one primary axis
- The number of simultaneously moving segment is typically limited to one.
- These types of exercises allow for more isolated muscle activation because less muscle co-contraction is used to perform the movement.
Closed Chain:
It is when the distal segment meets considerable external resistance prohibiting free movement. It is a system where neither the proximal nor the distal segment can move.
Characteristics:
- Linear stress pattern produced at the tibiofemoral joint due to axial joint loading.
- Movement at multiple joints and multiple -joint axes at hip, knee, subtalar joints.
- Simultaneous movement occurs at both segment.
What are Insertion and Origin muscles?The insertion and origin muscles are two different places where the bone is attached one at each end. Enthesis is the connective tissue between this attachment.
Insertion Muscles- The insertion muscles are connections to the bone via tendons. It is attached to the more movable bone.
Thus, this muscle is responsible for body movement. It is usually the distal end and has less mass.
Origin Muscles- Origin is the proximal site that stays more stable and relatively fixed during muscle contraction.
The head is a portion at the end of the origin muscle where it fixes to the bone. Some muscles can have more than one head.
Difference between two:
1. Insertion is more movable compared to Origin muscles as the former is attached to bone via tendons whereas the latter is less movable as it is attached via bone.
2. Insertion is a distal end attached to more movable bone whereas origin is proximal end attached to the less movable bone.
3. Insertion has less muscle mass whereas Origin has more muscle mass
4. Insertion moves with muscle contraction whereas Origin doesn't move during Muscle Contraction.

One of the distinguishing characteristics of nervous tissue is how difficult it is to repair damage to nervous tissue. Explain factors limit neurogenesis in the CNS of adults, why is it so hard to repair a damaged nerve
Answer:
Inhibitory influences from neuroglia, and the absence of growth-stimulating cues.
Explanation:
Neurogenesis in adults is limited by Inhibitory influences from neuroglia, mainly from oligodendrocytes, and the absence of growth-stimulating cues that are present during fetal development. It is so hard to repair a damaged nerve because nerve cell like other cells can't divide and increase in number, they can't renew themselves. Due to no division, the nerve cells does not increase in number and therefore can't repair themselves.

C. the expression of one gene masking the effects of another gene.
D. quantitative traits that diminish or intensify a particular phenotype.
E. the influence of environment on the expression of a particular genotype.
Answer:
the influence of environment on the expression of a particular genotype.
Explanation:
In genetics, we define penetrance as the proportion of individuals in a given population carrying a particular gene/allele which leads to the expression of the particular trait associated with that gene/allele.
Expressivity is defined as the degree of expression of a given phenotype by individuals who possess a particular genotype. Expressivity shows the extent of variation in expression of genes by individuals having a particular genotype.
Both penetrance and expressivity has to do with the influence of environment on the expression of a particular genotype.
