This indicates that the wings of house fly and bat are analogous organs.
What are analogous organs?
Analogous organs are the organs that are different anatomically in structure but perform the same function.
From the diagram, the wings of house fly and bat do not arise from same body part.
The wings of house fly have extra appendages attached at the back but that of the bat wings are modified
Hence, we conclude that both should be considered analogous to each other.

What is a key difference in gene expression between eukaryotic and prokaryotic cells?
Answer:The main difference between prokaryotic and eukaryotic gene expression is that the entire prokaryotic gene expression occurs in the cytoplasm whereas a part of the eukaryotic gene expression occurs inside the nucleus while rest occurs in the cytoplasm.
Explanation:Prokaryotic gene expression (both transcription and translation) occurs within the cytoplasm of a cell due to the lack of a defined nucleus; thus, the DNA is freely located within the cytoplasm. Eukaryotic gene expression occurs in both the nucleus (transcription) and cytoplasm (translation)

The features of ginkgophytes are:-
b. they produce sperm with flagella.
d. they are dioecious.
e. they produce seeds.
Ginkgophytes are the plants which belong to the division Ginkgophyta of Gymnosperms. These plants produce sperm which are flagellated. Ginkgophytes are dioecious, i.e. pollen-forming male reproductive structures and the female reproductive structures (ovules) are present on separate plants and not on the same plant.
Ginkgophytes produce seeds since they are Gymnosperms. However, these plants do not produce fruits. The entire reproductive cycle of the plant is completed in a period of about 14 months e.g. Ginkgo. Development of gametophytic phase takes place in the first year whereas, embryo development is completed by the time of spring in the next year.

Diseased animal cells may produce molecules that activate death cascades to kill the cells in a controlled manner. Why would neighboring healthy cells also die?.
Diseased animal cells may produce molecules that activate death cascades to kill the cells in a controlled manner. Neighboring healthy cells will also die because d. the death molecule passes through gap junctions.
Gap junctions are the intracellular connections that make it possible for neighboring cells to communicate with each other. The cytoplasms of the neighboring cells are able to exchange ions, molecules, impulses, etc through these gap junctions. Hence, these gap junctions are extremely important for the transfer of material between neighborly cells.
However, if healthy cells form gap junctions with diseased cells that form death molecules to kill themselves, then the death molecules can pass through the gap junctions to the healthy cells as well. As a result, the neighboring healthy cells will also die.
Although a part of your question is missing, you might be referring to this question:

Answer: The factor of safety in a plumbing system and determination of the upper limit of service for a 3-inch soil stack. 146. Establishment of a factor of safety.
Explanation:
The manipulated variable in the investigation is the diameter of the rubber tubing to determine its impact on siphoning time.
In the investigation exploring the impact of rubber tubing diameter on the time required to siphon water from a container, the manipulated variable is the diameter of the tubing. This variable is intentionally altered by the researcher to assess its influence on the siphoning process. By testing various tubing diameters, the researchers aim to observe any patterns or trends regarding the time it takes for water to be siphoned out.
This investigation seeks to determine if there is a correlation between tubing diameter and siphoning time. Controlling other factors, such as the volume of water, height difference, and tubing length, allows for a focused examination of the specific impact of tubing diameter on the efficiency of the siphoning process.

a) a small animal cell b) a large plant cell
URGENT!!!!
Answer:
A small animal cell is about 10 micrometers so:
10/6 = 1.7
The length of small animal cell is same order of magnitude as cell nucleus.
A large plant cell is about 100 micrometers so:
100/6 = 16.7
The length of large plant cell is an order of magnitude (10^1, or ten times) bigger than cell nucleus.
A small animal cell is about 10 micrometers so: 10/6 = 1.7
What is plant and animal cell?Plant cell contains cell wall. Animal cell do not have cell wall. The length of small animal cell is same order of magnitude as cell nucleus.
A large plant cell is about 100 micrometers so: 100/6 = 16.7. The plant cell is 10 times than nucleus of the cell.
Nucleus of the plant or animal cell is much smaller than the cell itself. The size of the cell is much more than size of nucleus.

An individual has inflamed connective tissue in the lungs which predicts that the individual will not breathe as efficiently, resulting in decreased oxygen levels in the body.
The mechanical structure and dynamic stability of the lung design are both supported by connective tissue. thus the connective tissue inflammation is related to the pleural membrane.
A membrane in the thorax called the pleura serves primarily as protection for the lungs.
Thus, the inflammation will cause problem in the exchange of the oxygen and carbon dioxide between the lungs membrane and the RBCs in the blood vessels and thus the individual will not be able to breathe properly and thus it will result in the decreased oxygen levels in the blood.

Water has a low viscosity (thickness). How might the movement of the dyes
change if a fluid with a higher viscosity is used? 1
The movement of the dyes would change in the negative if a fluid with higher viscosity is used. i.e lower movement of the dye through the medium
This is further explained below.
What kind of effects does viscosity have on the flow of fluid?Generally, One way to think about viscosity is as a measurement of the resistance that a fluid has to flow through it.
When compared to a fluid with lower viscosity, a liquid with a surface tension has a lower flow rate but a higher resistance, which is akin to having more friction.
This resistance may be thought of as the equivalent of having greater friction. To provide an example using language that is more accessible to people, we may state that the viscosity of a fluid is lower when it moves through its environment in a more orderly fashion.
In conclusion, If a fluid with a greater viscosity were utilized, the mobility of the dyes would be altered in an unfavorable manner. meaning that there is less mobility of the pigment throughout the medium

Explain why significant figures represent the precision of a measurement and not its accuracy.
Precision, on the other hand, refers to the variance you observe when you evaluate the same part again with the same tool. Accuracy, on the other hand, refers to the difference between both the measure and the part's real value.
Because there is less room for error in the approximated digit, measurements with more significant figures have higher repeatability or precision. A value with more significant figures is just more exact than a calculated values with fewer significant figures; it is not automatically more accurate. A value of 1.2 m, for instance, was measured using a less accurate measurement instrument, while a value of 1.5422 m was measured using a more exact measuring tool. The measurement made using the less accurate measurement instrument would be more precise if the measured object actually measured 1.19 m.

The bacteria shown in the figure has been magnified ten thousand times, as indicated by the value of the magnification factor.
What is the magnification of an object?When examined using a magnifying device such as a microscope, the size of an item seems to have expanded by a certain degree or quantity. This phenomenon is referred to as the magnification of the thing in question.
Magnification = size of the image/size of the actual object
Therefore
