Answer: B
Explanation: because it adapt to its environment to survive
The development of an organ system like a vascular system over a long period of time in plants is an example of evolution. Thus option A is correct.
What is evolution?Evolution is a series of events that have taken place in several years to make the species more advanced for the environment due to the introduction of multiple mutations in the genetic sequence.
During evolution, plants have gained the genetic mutation that codes for the vascular system which provide support and transports water in plants. So option A is correct.

explain how the mammalian skin perform it's role as a thermoregulatory
Answer:
The skin contains many blood capillaries and sweat glands ,the sweat glands secrete sweat when it is hot.when the sweat evaporates from the skin it cools the body.thermoregulation by the skin occurs through dilation and constriction of the blood vessels.when the bodies temperature raises,the blood vessels carry heat in the blood to the skin.the blood capillaries dilate become wider so that more heat can be lost to the environment.this is called vasodilation.when the outside temperature is low,the blood capillaries constrict become narrower so that less blood flows to the surface of the skin.therefore less heat is lost to the environment this is called vasoconstriction.

Which answer option below describes the best way to increase the accuracy of a
confidence interval calculation?
The accuracy of a confidence interval calculation can be increased from 95% to 99%.
Thus, option C is correct.
What is confidence interval?A confidence interval contain a population parameter in a specified proportion of the time, which can be computed using the given confidence level from a limitless level of individual sample.
The proportion of the range consists of the true value of the factor that will be identical to the confidence level.
In most of the confidence interval examples, the confidence level chosen is 95%. and it can be raise up to 99%.
It cannot estimate the plausible values of the unknown parameter of the population.
Two types of confidence interval observed such as accuracy which is defined based on whether the confidence interval contains the true population parameter or not.
Secondly, the precision defined in terms of the width of a confidence interval.
Hence, option C is correct.

A. Mesosome
B. Genophore
C. Peptidoglycan
D. Cell wall
Answer:
a
Explanation:
: an organelle of bacteria that appears as an invagination of the plasma membrane and functions either in DNA replication and cell division or excretion of exoenzymes.
The following part of the cell membrane that is folded in and thought to be used for helping DNA replicate is the mesosome. The correct option is A.
What is mesosome?Mesosome is a round organelle that is present in prokaryotic organisms like bacteria. These organisms present as introversion in the plasma membrane. This organ helps in many functions of the cell like DNA replication and cell division.
DNA replication is a process of replicating DNA in other cells. It happens in the process of cell division. In bacteria cells, mesosomes help in the distribution of DNA into the daughter cells during the division.

Given the range of current speeds shown on the graph above, would deposition ever be possible for clay (0.001 mm) or silt (0.01mm) particles?
Answer yes or no and explain your answer.
Answer:
Yes.
Explanation:
Yes, deposition can be possible for clay (0.001 mm) and silt (0.01mm) particles when the agent that carry its load is absent in that region such as wind. Wind is the agent that moves clay and silt particles with it so if there is high wind in a specific region, no deposition will occur while on the other hand, those areas where wind is not present, deposition will definitely occurs so we can say that deposition depends on the presence and absence of wind.
These bacteria rapidly divide until they run out of space. Their growth then slows down, and their population size stabilizes. What kind of curve would accurately show these changes in the population?
The correct answer is B. S-curve
Explanation
There are two models of population growth. One of them is the J-curve in which the population grows constantly without stabilizing, forming a J-shaped graph. Second, the S-curve is a model in which the population grows to a point, and from there it stabilizes, forming an S-shaped graph. According to the above, bacteria that divide rapidly until they run out of space and their growth slows down stabilizing the size of their population has an S curve model because the population does not grow unlimitedly but stabilized under specific circumstances. So, the correct answer is B. S-curve
The immunoglobulin light chain does not have a D segment. In humans, there are two different possible light chain proteins, termed kappa and lambda. Assume that there are 35 V segments and 5 J segments in the human kappa light chain region, and there are 30 V segments and 4 J segments in the human lambda light chain region. How many possible light chain genes can be created from these different segments, simply due to combinatorial diversity
Answer:
295
Explanation:
Antibodies (also known as immunoglobulins) are immune system-related proteins that circulate in the bloodstream in order to recognize pathogenic harmful substances (antigens) and neutralize them. An antibody consists of two immunoglobulin heavy chains and two immunoglobulin light chains. There are two types of immunoglobulin light chains: 1-the kappa (κ) light chain, which is encoded by the immunoglobulin κ locus; and 2-the lambda (λ) light chain, which is encoded by the immunoglobulin λ locus. The immunoglobulin light chain is a multidomain protein composed of two domains: 1- the N-terminal variable (V) domain and 2-the C-terminal constant (C) domain. V(D)J recombination is a type of somatic rearrangement process by which T and B cells can assemble different gene segments, which are referred to as variable (V), diversity (D) and joining (J) gene segments. In the question above the number of possible genomic recombination events between immunoglobulin gene segments can be calculated as >> (5 x 35) + (4 x 30) = 295.

Explain the self-correcting nature of science.
The notion of a self-correcting science is based on the naive model of science as an objective process that incorporates new information and updates beliefs about the world depending on the available evidence. When new information suggests that old beliefs are false, the old beliefs are replaced by new beliefs.

Hydrocarbons are burned to produce water and carbon dioxide. Propane (C3H8) is a homologous series alkane that belongs to the hydrocarbon family. As a result, when propane is burned, three molecules of carbon dioxide and four molecules of water are produced.
Because there is an overabundance of oxygen, carbon dioxide is created when butane is completely burned.
