This solar energy conversion process is known as photosynthesis. ... At this time, the oxygen level was approximately 10% of its present atmospheric concentration. ... The presence of ozone enabled organisms to develop and live on the land.
Answer:
- Vitamin A (fat absorption/liver disorder): Dry skin (i.e. eczema)
- Vitamine B1 (thiamine deficiency): Beriberi (wet or dry)..wet affect heart/circulatory system, dry can cause heart failure
- Vitamin C (ascorbic acid): anemia, gum disease, skin problems, and scurvy
- Vitamin D (calcium): bone loss/density; i.e. Rickets where bones become soft and bendable
Mineral dificiency (when your body does not absord or obtain the required amount of intake)
- Iron (important for hemoglobin); low iron can cause anemia (causes you to feel weak or tired)
- calcium (important for strong bones/teeth, supports proper function for blood vessels, muscles, nerves, and hormones); Calcium deficiency disease is osteopenia (left untreated it leads to osteoporosis--usually in older adults)
Explanation:
Answer:
W) filamentous actin
Explanation:
T cells are a type of white blood cells (leukocytes) that play a fundamental role in the immune system by determining the specificity of the immune response to specific antigens. In T cells, the remodeling of the actin cytoskeleton is critical for the movement of these cells through different tissue environments and for adjusting their behavior during the scanning of antigen-presenting cells. The actin cytoskeleton acts as a physical platform for intracellular signaling events that occur at the immunological synapse formed between a T cell and an antigen-presenting cell, thereby contributing to T cell activation.
The answer is RNA polymerases.
RNA polymerases are involved in the process of transcription, which reads the DNA and thanks to RNA polymerases, RNA is synthesized. Bacteria have a special type of RNA polymerases that made them <span>distinctively different from Archaea. Bacterial RNA polymerase is a large molecule that also catalyzes mRNA and ncRNA synthesis.</span>
