One of the bacteria in Model 1 has a tail-like structure.
a) What is the structure called?
b) What might be the purpose of this structure?
c) Based on your answer of the previous question, what might you infer about the absence of this structure in the other two bacteria cells?
Answers
From the bacterial model:
(a) the tail-like structure is known as the flagellum (plural, flagella)
(b) The primary function of the structure is to aid movement. It is moved in a whip-like version to propel the organism.
(c) Based on the absence of of flagellum in the other two bacteria, it means that they are not motile.
The presence of flagellum in bacteria is an indication that such bacteria are motile. The thread-like structure is whipped randomly in order for the organism to move and the absence of it in an bacterium is an indication that such a bacterium is not motile.

d. Combustion can occur anywhere but respiration only occurs in living cells.
Thanks in Advance!
Answers
Answer:
(c) In combustion, energy is released in several steps, whereas in respiration, it is released in a single step.
Explanation:
Combustion releases energy in a single step in the form of light and heat. Whereas in respiration, energy is released in steps and is stored in the form of ATP.

One could be forgiven for the assumption that the classic 'onion root tip squash' ... magnification using the eyepiece and objective lens, you will need to be able to ... about how the cells were being used, and had been given no explanation, ...
Explanation:
The cells of the ONION ROOT TIP undergo cytokinesis. This process is evidenced under the microscope by the formation of the CELL PLATE between two daughter cells.
Mitosis is a type of somatic cell division that has four main steps (prophase, metaphase, telophase and anaphase) followed by cytokinesis. Moreover, cytokinesis is the division of the cytoplasm to form two daughter cells.The cell plate is a transient compartment that grows between daughter cells. Once cytokinesis is completed, the cell plate gives rise to the cell wall.
In conclusion, the cells of the ONION ROOT TIP undergo cytokinesis. This process is evidenced under the microscope by the formation of the CELL PLATE between two daughter cells.

If you tossed a coin a total of ten times and got a total of three heads, what is the probability of tossing heads in your next toss?
Answers
0.95 is the probability of getting 3 Heads in 10 tosses.
In decimal form this is 0.5 and it converts to 50%
===================================================
Explanation:
Assuming the coin is a fair coin, meaning that each side is equally likely to be landed on, this means the probability of flipping heads is 1/2 = 0.5 = 50%
This is true of any flip. The coin doesn't have memory of previous events, so past events do not affect its probability. Each event is independent of any other.
The growth of plants stop if its apical part is cut,why？
Answers
Answer:
On some kinds of plants, the meristem is arranged so that when the tip of a branch or stem - which contains the apical meristem, from which new growth is initiated - is cut off, new stems or branches are signaled to start growing from the side, an area called the cambium or lateral meristem. These kinds of plants don’t die if the tip is cut off - instead they grow new branches.
Explanation:
good luck
Answer:
The apical bud produces a hormone, auxin, (IAA) that inhibits growth of the lateral buds further down the stem towards the axillary bud... When the apical is removed bud I'd removed, the lowered IAA concentration allow the lateral buds to grow and produce new shoots, which compete to become the lead growth

What is the name of a specific type of model that shows how animals diverge during evolution?(1 point)

cladogram
Answers
Answer:
Cladogram.
Explanation:
A cladogram is a diagram used in cladistics to show relations among organisms. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. In biology, taxonomy is the scientific study of naming, defining and classifying groups of biological organisms based on shared characteristics. Taxonomy would not be based on genetic diversion during evolution, it only describes similar characteristics amongst animals.
I also chose taxonomy on the test and it was wrong. The right answer said cladogram.
A specific type of model that shows how animals diverge during evolution is Cladogram. So, the correct option is D.
What do you mean by Evolution?Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms.
A cladogram is a diagram that shows the evolutionary relationships of several clades. A clade is a group of organisms, which contains both an ancestral species and its descendants. The common ancestor appears at the root of the cladogram.
Therefore, A specific type of model that shows how animals diverge during evolution is Cladogram.

Explain how Enzyme A acts as a catalyst in the reaction. Be sure to include energy and time in your answer.
Answers
Answer:
Enzyme A acts as a catalyst by lowering the activation energy the reaction needs in order to take place this would in turn lower the reaction time of the reaction lading to a faster reaction. when conditions around the enzyme change this may lead to the breaking of hydrogen bonds causing the active site to change in shape, this change would would lead to the substrate no longer being able to fit which would lower the rate of reaction.

O AO BO
As is demonstrated by the Punnett square, the children's genotypes will either be AO or BO. Since type O blood is recessive, no child will have O blood, as other dominant alleles are present. 50% will have type A blood and 50% will have type B blood.
