The endosperm of a Conifer seed is:
riadik2000 [5.3K]

Answer:

A. Haploid (n)

Explanation:

Conifers do not exhibit double fertilization that forms triploid (3n) endosperm in flowering plants.

Endosperm in conifers develops from the haploid cell of female gametophyte before fertilization. Since the endosperm is formed by the mitotic divisions in the haploid cell (n) of female gametophyte, it is haploid (n) in nature.

If a cell is placed in an isotonic medium, there will be no net movement of water. True or false?.
ASHA 777 [7]

It is true.

<h3>What is isotonic medium?</h3>
  • A solution that has the same amount of salt as cells and blood. In hospitalized patients, isotonic solutions are routinely utilized as intravenous fluids.
  • When a cell is immersed in an isotonic solution, there is no net movement of water into or out of the cell, and the volume of the cell remains constant.
  • Isotonic solutions include 0.9% normal saline and lactated ringers. A hypertonic solution is one that has a greater solute concentration than the solution across the semi-permeable barrier.
  • The isotonic solution allows the cells to move water and nutrients in and out of the cells. This is necessary for the blood cells to perform their function of supplying oxygen and other nutrients to other parts of the body.

Scientific investigations begin by asking questions that can be tested, measured, or both. Which question meets this criterion?
liberstina [14]
The answer choices are not provided, so I cannot select the correct one. However, I may provide you examples and guidance on how to choose the correct one.
As mentioned in the explanation, a scientific question must have a variable that is changed, the independent variable, and a variable on which the effect of the change is measured. This is the dependent variable. Examples of such questions include:

How will the amount of water given to a plant affect its rate of growth?
What will be the amount of sugar that can be dissolved in water at a given temperature?
At what temperature will a balloon filled with air pop?

All of these questions may be tested using experiments.
