Answer:
The correct answer is - option A
Explanation:
Phosphoinositide 3-kinases or PI-3 kinse, are enzymes involved in essential cellular functions such as the growth of the cell, proliferation, motility, differentiation, survival and intracellular movement, which in turn are plays role in cancer.
PI3-kinase with oncogene PIK3CA and tumor suppressor PTEN, is implicated in the insensitivity of cancer tumors.
Thus, the correct answer is option A)
Answer:
According to the illustration of meiosis I, when sister chromatids stay together the phase to which it corresponds is telophase I (fourth option).
Explanation:
Meisois is a process of cell division whose final result is the obtention of two daughter cells with half of their genetic charge, with respect to the original cell. This process is divided into two parts, called meiosis I and II.
Telophase I corresponds to the phase of cell division in meiosis I, where the events that occur are the appearance of the nuclear membrane on the newly divided genetic material, cytokinesis -or cytoplasmic division- and above all due to the fact that each daughter cell already contains half of the genetic load, since the sister chromatids stay together.

Answer: The correct answer for the first question is- B) Mechanical.
Adaptation can be described as a process of change in an organism over time that facilitates its survival in the changing environmental conditions. It results due to mutation or genetic change in the individual that gives a benefit to the organism. It exhibits change in structure ( like succulent plants in desert), function, or behavior.
Mechanical is not a type of adaptation as it deals with movement of objects.
The correct answer for second question is- C) Variations.
Variation among organisms in a population results from change in the genetic material or their genetic sequences. Change at the genetic level is thus reflected in the phenotypes ( like different color of feathers in birds).
Thus, difference is in the feather color reflects variations.
. I think that bivalves have evolved to have smaller head regions because they have also evolved to have bigger shells or valves than cephalopod
