Answer:

seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with seedling of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves). The two classes of flowering plants (angiosperms) are distinguished by their numbers of seed leaves: monocotyledons (monocots) have one blade-shaped cotyledon, whereas dicotyledons (dicots) possess two round cotyledons. Gymnosperms are more varied. For example, pine seedlings have up to eight cotyledons. The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons.The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule does not occur until the cotyledons have grown above ground. This is epigeal germination. However, in seeds such as the broad bean, a leaf structure is visible on the plumule in the seed. These seeds develop by the plumule growing up through the soil with the cotyledons remaining below the surface. This is known as hypogeal germination.

1. What type of response will a red blood cell have when placed in a hypertonic solution?
GalinKa [24]
Hypertonic solution means the solution with a lower water potential than the cell cytoplasm, such as salt water.

When the red blood cell is put into it, since the cell has a higher water potential than the solution, water molecules will flow from the cell back into the water due to osmosis.

Osmosis is always where water molecules flow from a region of higher water potential to lower, through a semi permeable membrane (Whcih is the red blood cell membrane in this case.)

Since water flowed out of the cell, the cell lose water and shrinks.

Hypotonic solution is where the solution that has a higher water potential than the cell cytoplasm.

So when the red blood cell is put in that solution, the water will flow from the solution into the cell this time, by osmosis.

The red blood cell will then gain so much water that the cell membrane cannot hold all and therefore burst.

What is not a characteristic of the cortical nephrons?
Pani-rosa [81]

Answer:

Their nephron loop is closely wrapped with vasa recta.

Explanation:

Cortical nephrons are located in the cortex.

They form 85% of all the nephrons in the kidney. They are located mostly within superficial cortex of kidney. The loop of henle of a cortical nephron is relatively short and hence not closely wrapped with vasa recta. Efferent arteriole delivers blood to a network of peritubular capillaries.
