Answer and Explanation:
Microscope objects have thermal profiles. These profiles differ as a purpose of their physical parameters. Most objects are sold and designed for the resolution of fixed cell microscopy.
There is little indication that the temperature cycle affects the strain characteristics. A large box can be constructed around the microscope and heated with hot air.
The heating system's cycling causes the specimen to drift out of focus and can also change the coverslip position.
The microscope can be equilibrated to a single temperature to eliminate the movement resulting from the thermal expansion of the microscope's components.
Air currents connecting the specimen chamber should also be reduced—tight control of temperature for the entire laboratory and microscope. Any change in the temperature can lead to unwanted movement in the microscope. Heating ducts often produce localized temperature changes.

What is phagocytosis in regard to the immune system of humans?
Answer:
Phagocytosis is the process of introducing larger particles into a larger cell. The process takes place by twisting the cell membrane of the "host" and enveloping the particles with a phagocytic bubble. Leukocytes use phagocytosis to take in and incapacitate bacteria that enter our body, so phagocytosis plays an important role in the immune system, as it prevents harmful cells from affecting humans.
Answer:
the process by which neutrophils ingest a bacterium
Explanation:
Neutrophils ingest bacteria via a process known as phagocytosis, or "cell eating." (also, I took the quiz)
In sweet pea plants, purple flower color is dominant over red flower color and long pollen grain shape is dominant over round pollen grain shape. Two sweet pea plants that we heterozygous for both flower color and pollen grain shape are crossed with one another. A geneticistis surprised to observe that there are fewer round purple offspring and long red offspring than were predicted by the 9:3:3:1 expected phenotypie ratio Which of the following statements provides the most reasonable prediction to account for the deviation from the expected results?
A) in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked
B) In sweet pea plants the genes for flower color and for pollen grain shape both exhibit codominance
C) Several mutations occurred spontaneously producing a deviation from the expected phenotypic ratio of the offspring
D) The genes for flower color and pollen grain shape are inherited independently because of the law of independent assortment
Answer:
The correct answer is - option A) in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked.
Explanation:
In this given case the result of phenotypes are not as expected and does not follow the law of independent assortment presented by Mendel. It appears to be the case of genetic linkage as it is not following the mendelian law by producing fewer round purple offspring and long red offspring which do not satisfy the expected mendelian ratio of 9:3:3:1. Mutation can lead to failure in producing proteins but could not affect the phenotypic ratio of the plant.
Thus, the correct answer is - option A.
Medel was the Father of Genetics, who gave the laws on independent assortment, dominance, and segregation of the genes.
However, there are some exception that violates these laws, such as genetic linkage is one of the exceptions that violates the law of independent assortment.
The correct answer is:
Option A. in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked
In the given data, the results can be interpreted as:
The Law of independent assortment states that the two or more alleles of different genes are assorted independently. In the given example, the genetic linkage occurs, which does not follow the ratio of 9:3:3:1. The genetic linkage does not follow the law of independent assortment, which results in fewer purple offspring.Thus, mutation can cause the failure of Mendel laws and can affect the phenotypic traits of an organism.
Therefore, Option A is correct.

Hopetown is farther from the equator than kamina. Which location has colder air temperature and why
Answer:
Hopetown
Explanation:
The farther from the equator the colder the air temperature. This is because the equator is the point on planet Earth that receives the largest amount of solar energy, so the regions that are above this line are the warmest in the entire planet. The further away from the equator a region is established, the less solar energy it receives, which is why the poles are so cold. In this case, we can say that the Hopetown temperature is colder than the kamine temperature.

How have human activities effected the air in earth’s atmosphere?
Answer:
Human activities have had a negative impact on Earth's atmosphere.
Explanation:
Human activities, since the Industrial Revolution, have gradually been having more and more influence on Earth's atmosphere. As more and more the economies have developed, the bigger and bigger the output of gases into the atmosphere. The gases that are released into the atmosphere are mostly greenhouse gases, but there are also some that are highly toxic.
This has contributed to a sharp increase in CO2 levels in the atmosphere, which is speeding up the process of global warming, and that can have devastating consequences for life on Earth. Also, some of these gases managed to cause huge damage to the ozone layer, the layer that protects us from UV radiation, and if the ozone is gone, every complex organism will be gone as well.
Reset Label each step in the Scientific Method and then place the steps in the correct order. ____________ : Set of conceptual assumptions that explains data from accumulated experiments; predicts related phenomena. ____________ : Tentative proposal that explains observations. ____________ : Procedure to test hypothesis; measures one variable at a time. ____________ : Tests predictions based on model.
Answer:
The correct answer is - model (theory), hypothesis, experiment, further experiment.
Explanation:
A model or a theory is a set of assumptions based on concepts or facts that describe the data acquired from the experiments.
A proposed explanation for the observations is a hypothesis. It required experiment to be proved
A scientific experiment is a procedure to test a hypothesis and it can only measure a single variable at a time.
further experiment is required to tests predictions based on model.
In the fourth century BC, Aristotle observed a phenomenon in which he saw a circular shadow on the Moon. He argued that Earth was a sphere based on this observation. What phenomenon caused the shadow on the Moon? *
a solar eclipse
a lunar eclipse
a spring equinox
a summer solstice
Answer:
a lunar eclipse
Explanation:
The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.

The trait for tall pea plants is (T) and the trait for short pea plants is (t). The trait for smooth pea plants is (R) and the trait for wrinkled is (r).Two plants are crossed producing a F1 generation of plants with 612 tall and smooth pea plants and 188 short and wrinkled pea plants.What would be the most likely genotype of the parental generation?
Answer:
P generation = TtRr × TtRr i.e both parents were heterozygote for both traits
Explanation:
This question involves two genes encoding the height and texture in pea plants respectively. The alleles for tall and smooth pea traits are dominant over the alelles for short and wrinkled traits.
According to this question, two plants are crossed to produce F1 offsprings as follows: 612 tall and smooth pea plants and 188 short and wrinkled pea plants.
First, we turn this derived number of offsprings into ratio by dividing by the smallest number (188)
612/188 : 188/188
3.25 : 1
Approximately; we can say this is 3 (tall and smooth) : 1 (short and wrinkled)
Based on this ratio, which was got by Mendel for his F1 offsprings when he crossed pea plants, the parental generation has a heterozygous genotype (TtRr).

2. Name a microbe that lacks a cell wall and would find hypotonic environments detrimental.
Answer:
I so I am also a bit confused, but I hope this could answer your question!
Explanation:
The bacteria possess a cell wall composed of peptidoglycan molecule formed by the amino acids called murine. The bacterial cell wall helps in the survival of the bacteria in some extreme condition like when placed in a hypotonic solution.
The hypotonic solution is formed when it has low solute concentration and high water amount when compared. When the bacterial cell will be placed in hypotonic solution then the water will move inside the cell down the concentration gradient as a result of which the bacterial cell will swell but will not burst.
This happens as the cell wall contains expansin protein which allows the cell wall to expand and provides rigidity to the cell.

What is true about cardiac (heart) cells compared to brain cells?
Different DNA which make different proteins
Same proteins being used to create different DNA
Same DNA being used to make different proteins
Different proteins used to create different DNA
Answer:
Same DNA being used to make different proteins
Explanation:
Cells of all living organisms contain the genetic material called DNA. One of the characteristics of multicellular cells is the ability of their cell to DIFFERENTIATE i.e. form specialized cells during division.
However, it is worthy to note that all cells possess the same DNA but some of the genes contained are expressed into proteins while others are not. This leads to why cells that contain similar DNA make different proteins and perform differently.
In this case, cardiac (heart) cells and brain cells contain the same DNA but due to the expression of some genes and repression of others, they are able to differentiate into different cells.

The respiratory rate times the tidal volume corrected for the dead air space in the lungs is the __________.
a. vital capacity
b. respiratory minute volume
c. pulmonary ventilation rate
d. alveolar ventilation rate
e. external respiration rate
Answer:
d. alveolar ventilation rate
Explanation:
Alveolar Ventilation rate (AVR) refers to the rate of airflow that reaches the alveoli which is available for gas exchange with the blood in a given unit of time. AVR is generally calculated as the amount in millimeters of air expired that equilibrates (i.e., exchanges) with alveolar gas per min unit (ml/min). AVR is affected by breathing frequency, tidal volume ( i.e., the normal amount of air between inhalation and exhalation), and the amount of dead space in the lungs.
