The best conclusion to make if no chiasmata is observed in a species is that crossing over does not occur in that species.
What is chiasmata?Chiasmata is the contact point between the two chromatids of a chromosome during the prophase stage of meiosis.
Chiasmata forms during the process of crossing over in meiosis, where sister chromatids of non-homologous chromosomes exchange genetic material.
According to this question, the events of meiosis I in cells from several different organisms is being compared. However, no chiasmata was observed in a particular species.
Therefore, the best conclusion to make if no chiasmata is observed in a species is that crossing over does not occur in that species.

During the cell cycle, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. at the end of this cycle, the cyclins degrade to prevent further signaling for the cell to divide.
uncontrolled production of cyclins will most likely result in —
f) the formation of tumors
g) the immediate death of the cell
h) the transfer of cyclins to other cells
j) the formation of haploid cells
Uncontrolled production of cyclin proteins will most likely result in the formation of tumors (Option f).
What are cyclins?Cyclins are proteins that control the progression through the cell cycle by their interaction with specific kinases.
These cyclins-dependent kinases (cdks) can be phosphorylated as a control points during the cell cycle.
Uncontrolled production of cyclins will produce uncontrolled cells that divide forming tumors.

how many cells are in this picture? and which phase are most of the cells in-interphase, mitosis or cytokinesis
Answer:
~100 cells,
Explanation:
I counted around 102 cells in the picture. For your seond question I am a bit confused.
You asked what phase are they in and gave interphase, mitosis and cytokineses as the options. While interphase and cytokinesis are phases of mitosis. Therefore in theory all the cells are going through mitosis.
Since most of the cells are looking like dense balls, we can say they are going through interphase.
P.S. I also see some going through anaphase, metaphase and cytokinesis, but they are seldom in numbers compared to interphase cells.

There is a maximum between the two input values -2 and 2.
A quadratic function is the function which has 2 as its highest power. Its genralised form is given as y=ax²+bx+c.
From the given table it can be observed that at extreme values of x, therefore, when x=-5 and x=9, the value of y is negative. Therefore, at any value above 9 and below -5, the value of the function will be always negative.
Further, it can be observed that the highest value of y is 9 which when the value of x is -1.
The only choice from the given option that includes -1 in its answer is -2 and 2.
To verify this a graph can be plotted for the function as shown below.
Hence, the maximum will be between -2 and 2.
