Answer:
- A signal for apoptosis that comes from outside the cell is when a cell detaches from extracellular matrix. If this happens, a transmembrane signal is triggered.
- Two examples of cellular occurrences that would prompt an apoptosis signal from inside the cell are:
1. Damaged DNA
2. Increase of cytosolic calcium concentration
Explanation:
Apoptosis can be activated from an intrinsic or an extrinsic pathway. The intrinsic pathway is activated when a cell senses stress (for example, damaged DNA or high cytosolic calcium concentration) and triggers death proteins to activate apoptosis mechanism inside of it; the extrinsic pathway refers to the apoptosis triggered by signals that come from other cells. In this scenario, ligands bind to cell-surface death receptors and activates a death-inducing signal.
Answer:
look,Examples of X-linked recessive conditions include red-green color blindness and hemophilia A: Red-green color blindness. Red-green color blindness means that a person cannot distinguish shades of red and green (usually blue-green), but their ability to see is normal.
Answer:
When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down.

Answer:
d. consumer
Explanation:
Zebra and Deer are consumer (to be specific they are primary consumers) because they feed on plants only. Producers are organisms that create the food such as plants.
The subcutaneous layer is mainly made of <u>fat tissue.</u>
One of the three layers of skin is the subcutaneous layer, which lies below the dermis. The deepest layer of the skin is primarily made up of fat. It also contains collagen, blood vessels and nerves. The body's fat creates a layer that protects the organs from damage and acts as insulation against the cold. Additionally, it gives the skin structural support.
The depth of the subcutaneous layer in the body's abdominal region, which frequently has higher percentages of fat, can reach three centimeters. The thickness is determined by the person's overall body fat percentage. Other places, like the eyelids, have a subcutaneous layer that is as thin as 1 millimeter and devoid of fat.
The subcutaneous layer has many functions, including insulation, thermoregulation, shock absorption, structural support, and energy storage.
