It should be noted that muscles only work to produce movement through pulling, muscles cannot push. Therefore, the statement is true.
Muscles allow people to move by pulling in the joints. Muscles are required to breathe, exercise and stay healthy.
There are three main form of muscles in the human body and they're:
• Skeletal muscles: The muscles give the body its shape as they help in holding the skeleton together.
• Smooth muscle: They're also called the involuntary muscle. They consist of fibers and are controlled by the nervous system. They help in maintaining blood pressure.
• Cardiac muscle: This is the muscle that's found in the heart. It helps in ensuring that the heart function well.
In conclusion, muscles only work to produce movement by pulling, they cannot push.

Postpartum urinary retention can be caused by: a. Stretching of the ureters during delivery b. Decreased sensitivity to bladder fullness c. Contraction of bladder muscles caused by oxytocin d. The effects of proteinuria and lactosuria on the bladder
Answer:
a. Stretching of the ureters during delivery
Explanation:
Postpartum urinary retention is defined as the stretching if the uterus or the genitourinary tissue which occurs in most of the women during vaginal deliveries. The postpartum bladder is vulnerable to the urinary retention. This occurs due to the physiological changes in the pregnancy period. During delivery through vagina, the genitourinary tissues becomes edematous and also gets traumatized form the labor process and thus stretches the ureters during the delivery time. But it returns to normal after 4 to 6 days of diagnosis.
Hence the correct option is (a).

The concentration of reactants and products and the rate of reaction were measured during a chemical reaction. After the first 3 seconds, the rate of reaction was 1.8 x10−6 M/s. Which of the following would explain a lower rate after another 3 seconds?
The concentration of reactants increased while the concentration of product decreased.
The concentration of reactants decreased while the concentration of product increased.
All concentrations of reactants and products decreased.
All concentrations of reactants and products increased.
Answer:
The rate of reaction refers to how quickly or slowly the reactants disappear or the products appear in a given reaction. The rate of reaction depends on the concentration of the reactants. Thus, as concentration decreases with time, the rate of reaction decreases accordingly.
Therefore, reaction rates tend to decrease with time since the concentration of the reactants decrease with time as the reactants are being converted into products. Thus after three seconds, the rate would be lower, and the concentration of reactants would be lower.

Which statement is true about a reversible reaction?
It has equal mass of all reactants.
It produces salts from acids and bases.
It has equal number of products and reactants.
It results in an equilibrium mixture of reactants and products.
Answer:
It results in an equilibrium mixture of reactants and products.
Explanation:
A reversible reaction is a type of reaction where reactants react to give rise to products and in the same vein, products react to give rise to reactants again. That is;
A + B (reactants) ⇌ C + D (products)
For example, in the above reaction, C and D are formed simultaneously with the reformation of A and B. Based on this, an equilibrium mixture of reactants and products occurs in a reversible reaction. This means that there is no net change or difference in the formation of A and B or C and D.
Answer:
It results in an equilibrium mixture of reactants and products.

Risk assessment is often used to set “acceptable” levels of toxins for the environment. Propose a concern people may have about using risk assessment in this way.
The concern about risk assessment of acceptable levels of toxins can be a failure to use appropriate risk metrics, incorrect measuring of known risk, failure to take known risks into concern, or failure in risk communication or risk monitoring.
What is meant by risk assessment?A risk assessment is a step-by-step process that, in combination with an exposure analysis and other elements, provides an estimate of the likelihood that an adverse health event will occur as a result of ingestion, inhalation, or absorption of one or more toxins. One of the most important aspects of risk assessment is toxicity assessment.
A toxicity assessment is a study of a substance’s ability to cause harm – and how much harm it can cause. It’s important to note that not all substances are toxic – many therapeutic medications are acute toxic but beneficial when taken at the right dose.

Darwin presented a hypothesis about how evolution takes place. Now this hypothesis has become a theory. What caused the idea to become a theory? A. Darwin shared his ideas with others, and many scientists have performed experiments that support this idea. B. Darwin is well respected, and scientists honor his work by referring to his idea as a theory. C. Darwin performed an experiment that supported his hypothesis. D. Darwin convinced everyone around him that it was a good idea.
Answer:
C. Darwin performed an experiment that supported his hypothesis.
Explanation:
Darwin believed that his experiment, which was comparing the finch's beaks from Galapagos Archipelago, in which there was variation between the size and shape of beaks, as the basis in which he believed evolution was correct. However, variation does not mean evolution, and evolution, in which it calls for a chain of events to create beneficial traits successively, is nigh impossible to occur in the real world. Again, that is not to say that there is no such thing as variation, in which there is, in which people or animal groups adapt to their natural habitat. However, to state that adaptation is proof that a species becomes another is to go out on a limb, and current failures of "new species" (in that it originates from today's day and age, rather then discovered) to emerge is proof of such.
Analysis of the effect of lectin using chi-square analysis In science, it is not sufficient to say "My results look pretty good. More cells treated with lectin are in mitosis compared to those in the control, which supports my hypothesis that lectin is a growth promoter." A valid conclusion must be supported by appropriate statistical analysis. In this activity, the appropriate tool is the chi-square test. Because this test can be applied across many different situations, your instructor will introduce you to it when appropriate for your course. In chi-square analysis, you always begin with a null hypothesis. The null hypothesis states that there is no statistically significant difference between the results in the control group compared to the experimental group. If the null hypothesis is rejected (a null hypothesis is either rejected or not rejected) because variation between the control group and experimental group is too great, this lends support to an experimental hypothesis. In this case, the experimental hypothesis was that lectin is a growth promoter.If you do a chi-square analysis of the results of a study to compare the number of cells in interphase versus those in mitosis for both lectin-treated and untreated cells, which of the following would represent an appropriate null hypothesis?A. If lectin promotes cell division, then more cells will be in interphase than in mitosis when compared to a control. B. There should be no significant difference between the cells in interphase versus those in mitosis in the two treatments. C. There should be a significant difference between the cells in interphase versus those in mitosis in the two treatments. D. If lectin promotes cell division, then more cells will be in mitosis than in interphase when compared to a control.

Many alcohols are made using a fermentation process where the bacteria and materials are sealed without oxygen. These bacteria use anaerobic respiration. How would their energy efficiency compare to aerobic bacteria?A. Energy efficiency is not related to the type of respiration. B. They will have an equal energy efficiency. C. They will have a lower energy efficiency. D. They will have a higher energy efficiency.
Answer:
The correct answer is: C. They will have a lower energy efficiency.
Explanation:
Similar to aerobic cellular respiration, anaerobic cellular respiration uses electrons taken from a fuel molecule to drive ATP production through an electron transport chain. Bacteria and archaea are prokaryotes that survive in low-oxygen conditions and use anaerobic respiration to break down energy.
Methanogens, for example, can employ carbon dioxide as a terminal electron acceptor and produce methane as a by-product. Methanogens may be found in soil as well as in the digestive tracts of ruminants. Fermentation is another anaerobic (non-oxygen-requiring) process for breaking down glucose that is used by a variety of species, including bacteria.
However, the glucose breakdown performed by anaerobic respiration isn't complete and thus, the energy released is 19 times less than aerobic respiration for the same amount of glucose.
Which phase of the cell cycle is the least common process of mitosis and what could be the reason?
Answer:
In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell. By the end of anaphase, the 2 halves of the cell have an equivalent collection of chromosomes. In telophase, 2 daughter nuclei form. The nuclear envelope beings to reappear.
When an artery gets a constricted region due to plaque, how does the pressure in this region compare to the pressure in an unconstricted region adjacent
Answer:
Pressure increases.
Explanation:
When an artery gets a constricted region due to plaque, the pressure in this region increases as compared to the pressure in an un-constricted region where the pressure is normal because in the non-constricted region there is no narrow artery and the blood flows normally. When the artery becomes narrow due to deposition of any materials, the blood pressure increases so that's why we can say that the pressure increases in the artery in constricted region.
A constricted region in an artery will cause blood to flow with more pressure as compared to unconstricted regions.
Remember that pressure is the ratio of force and area.
Mathematically; Pressure = Force/Area.
This means that the higher the area, the lower the pressure and vice versa granted that the force remains constant.
A constriction in an artery due to plaque will reduce the area of the artery through which blood flows. Thus, the blood in this area will flow with more pressure compared to the unconstricted regions on the same artery.

Describe the relationship between the surface area and the volume of a cell. Analyze the data and explain why cells are often flattened instead of cube-shaped.
Answer:
Inverse relation.
Explanation:
There is an inverse relationship between the surface area and the volume of a cell because one increases the other decreases. When a cell grows bigger in size, its internal volume enlarges and the cell membrane start expanding. Unfortunately, the volume increases more rapidly than the surface area of the cell. So the surface area available to pass materials to a unit volume of the cell steadily decreases. Cells are often flattened instead of cube-shaped because the surface area increases. Due to surface area increases, more materials to be absorbed through the cell membrane at a greater rate than that of a cell with smaller surface area.
