is the insect respiratory system more or less effective compared to the human respiratory system?
I'd say more effective.
"Insects have a more efficient respiratory system than humans. "
But at the same time insects don't have any lungs they breathe through the help of trachea/tubes/and or holes along their abdomen area.
You need to think about how small, compared to us humans, and insect is. They can take in a lot more oxygen than we can (for their size)
If we were to be able to shrink until we're the same size as an insect, they would be the ones taking in way more oxygen because of the way their system is constructed.
Which structures are similar in function, but do not indicate that the organisms are related?
analogous structures
homologous structures
vestigial structures
transitional structure
Answer:
A
Explanation:
analogous structures
Analogous structures are similar in function but do not necessarily suggest that the organisms are related.
What are analogous structures?The term “analogous” is used to describe biological structures that have similar or analogous functions but are not of the same evolutionary lineage. This means that the same biological structures are used by the same species for the same purposes, but the species are from different evolutionary origins. This type of evolution is called convergent evolution.
For example, similar structures of different species might have similar or equivalent functions, even though they originated from a different evolutionary point of view.
The wings of birds and insects are similar organs. Both birds and insects have wings that allow them to fly. However, their wings come from different ancestors. This is an example of analogous structure.

What are the processes involved in cellular division?
Answer:
I hope this helps!!
Explanation:
The existence and perpetuation of life depend on the functioning of cells and their divisions. There are two important processes of cell division, which are inextricably linked with each other to maintain the progress of life. These processes are Mitosis and Meiosis.
After fertilization, when a sperm cell and an egg cell unite to form a new organism, it is expected to carry a double number of chromosomes because both the parents contribute their whole number of chromosomes as appropriate for the respective species. But the process of meiosis prevents the doubling of the chromosomes.
It reduces the total number of chromosomes in half so that the offspring (newly formed cell) can retain the same number of chromosomes as the parents. On the other hand, mitosis facilitates in forming of two daughter cells from a single cell where each new cell resembles the parent cell in every respect. Unlike meiosis, mitosis involves duplithe cation of chromosomal pairs, which is essential for cellular reproduction, especially during growth.
The Mechanism of Mitosis:
A specific process is required for forming two daughter cells out of a mother cell. This process is known as mitosis and it is usually divided into four stages, prophase, metaphase, anaphase, and, telophase. In some cases, it is convenient to designate the transition from prophase to metaphase by the name of prometaphase. However, the whole process of the cycle of mitosis is a continuous one.
1. Prophase:
At the beginning of the prophase stage, the cell prepares itself to divide the chromosomes. It is the resting stage when the nucleus becomes a little larger. It also involves the condensation of the previously diffuse, invisible, or dispersed threads into visible chromosomes.
Each chromosome is optically double, which is composed of two identical and closely parallel strands or chromatids lying throughout their length. A chromosome bears a constriction or a narrow region of attachment to the spindle, which is called a centromere.
Constrictions other than the centromere are sometimes called ‘secondary constrictions’.At prophase s,tage the centromere and secondary constrictions look alike, but by metaphase, this distinction is clear because they develop entirely different relations to the spindle.
In this stage (prophase) the outlines of the chromatids present a slightly irregular woolly or hairy appearance. They do not, in general, show a series of granules (chromo-meres) as are seen at the meiotic prophase, and probably this is a real difference between the two. By the end of the prophase, the woolly appearance almost disappears and a smooth outline is visible.
2. Premetaphase:
At the end of the prophase, the nuclear membrane usually disappears and this stage may be defined as the period of spindle formation. During this stage, the chromosomes give an impression of struggling and pushing among themselves too to reach the equator of the developing spindle. The spindle is relatively a solid gelatinous body. It is composed almost entirely of protein with a very small amount of RNA.
The centrosome seems to act as an organizer of the spindle. The centrosome is the differentiated region of cytoplasm containing centriole, which is a minute granule present just outside the nuclear membrane. After the disappearance of the nuclear membrane, the centriole is doubled and the two centrioles move apart from each other to form the poles of the spindle.
The spindle fibers are probably bundles of protein molecules. A distinction may be made between continuous fibers and chromosomal fibers. The continuous fibers run from pole to pole whereas the chromosomal fibers connect the centromeres to the poles.
In the case of bipolar spindles, the equatorial plane is located perpendicular to the long axis, which is the midway between the poles. As the prometaphase proceeds, the chromosomes arrange themselves with their centromeres, on the equatorial plane of the spindle. It is the most dynamic stage which gives rise to a relatively static Metaphase.
A local biologist needs a program to predict population growth. the inputs would be: the initial number of organisms, as an int the rate of growth (a real number greater than 1), as a float the number of hours it takes to achieve this rate, as an int a number of hours during which the population grows, as an int
"A local biologist needs a program to predict population growth. the inputs would be..." The resultant code is
tp=sp
hours = 1
while (hours < t):
tp *= g
hours += r
print("The total population is " + str(int(tp)))
# the call function
What is a program?Generally, a program is simply defined as programming written into a computer or other equipment in order to do a certain task
In conclusion, to write a program that takes these inputs and displays a prediction of the total population must consider the parameters and the code platform (python), Hence
# on python interface required library is explored
import math
# describe the functions needed
def prediction():
sp = int(input("Enter the initial number of organism: "))
g = float(input("Enter the rate of growth [a real number > 0]: "))
while(g<1):
print ("Invalid.. growth rate.")
g = float(input("Enter the rate of growth [a real number > 0]: "))
r = int(input("Enter the number of hours to achieve the rate of growth: "))
t = int(input("Enter the total hours of growth: "))
tp=sp
hours = 1
while (hours < t):
# the calculation for tp
tp *= g
hours += r
print("The total population is " + str(int(tp)))
#call the created function
CQ
A local biologist needs a program to predict population growth. The inputs would be: 1. The initial number of organisms 2. The rate of growth (a real number greater than 1) 3. The number of hours it takes to achieve this rate 4. A number of hours during which the population grows. For example, one might start with a population of 500 organisms, a growth rate of 2, and a growth period to achieve this rate of 6 hours. Assuming that none of the organisms die, this would imply that this population would double in size every 6 hours. Thus, after allowing 6 hours for growth, we would have 1000 organisms, and after 12 hours we would have 2000 organisms. Write a program that takes these inputs and displays a prediction of the total population.
