What does a red blood cell look like at in 0.65M solution

Ket [755]

It depends on what kind of solution is referred as 0.65 M. If the solution where the red blood cell is present is hypertonic, the red blood cell will shrink. If the solution is hypotonic, the red blood cell will expand. If the solution is isotonic, the red blood cell will not expand or shrink.

What term is used when the concentrations of solutes inside and outside a cell are in equilibrium?

Schach [20]

Isotonic solutions is the term used when the concentrations of solutes inside and outside a cell are in equilibrium.

Explanation:

The isotonic solution is one which have same osmotic pressure on either side of the semi-permeable membrane.

In the isotonic solution there will be free movement of only water molecules and not solutes.

isotonic solution is the solution when two solutions have equal solute concentration.

The concentration of the solution will be in equilibrium.

List at least four factors that

lord [1]

Answer:

Differences in temperature or precipitation determine the types of plants that grow in a given area (Figure 1). Generally speaking, height, density, and species diversity decreases from warm, wet climates to cool, dry climates. Raunkiaer (1934) classified plant life forms based on traits that varied with climate.

After fertilization a zygote forms. The cells then go through mitosis. Explain how this bundle of cells eventually forms a human

yaroslaw [1]

Answer:

Human fertilization and development

Fertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote. To ensure that each zygote has the correct number of chromosomes, only one sperm can fuse with one egg.

Stages of human development

Zygotic stage: The zygote is formed when the male gamete (sperm) and female gamete (egg) fuse.

Blastocyst stage: The single-celled zygote begins to divide into a solid ball of cells. Then, it becomes a hollow ball of cells called a blastocyst, attaching to the lining of the mother's uterus.

Embryonic stage: The major internal organs and external features begin to emerge, forming an embryo. In this stage, the heart, brain, and spinal cord become visible. Arms and legs start to develop.

Fetal stage: Once the formed features of the embryo begin to grow and develop, the organism is considered a fetus. Differentiation and specialization of structures happens during this time.

Differentiation and apoptosis

During development, the number of cells must increase through division so that body axes, tissues, organs, and structures must form. Individual cells become specialized in their structure and function through the process of cell differentiation.

Unnecessary cells also must be removed in order to help form important structures. This occurs is through the process of apoptosis. For example, human hands start out as a paddle-like block of tissue. Eventually, the block was “carved” into fingers by apoptosis of the cells in between the developing fingers.
