Chlorella is a genus of about thirteen species of single-celled green algae belonging to the division Chlorophyta. The cells are spherical in shape, about 2 to 10 μm in diameter, and are without flagella. Their chloroplasts contain the green photosynthetic pigments chlorophyll-a and -b. In ideal conditions cells of Chlorella multiply rapidly, requiring only carbon dioxide, water, sunlight, and a small amount of minerals to reproduce.

Head lice can survive on a human host for approximately 30 days. Head lice generally cannot survive longer than 24 hours off the host. A female louse lays up to 3-5 eggs per day. It takes 7-10 days for the eggs to hatch and another 7-10 days for the louse to mature and lay their own eggs.

Many ocean species (especially large ones like whales, sharks, and sea turtles) follow ocean currents to and from their feeding and breeding grounds.
Answer: B. The release of calcium ions causes myosin and actin to attach to each other. This statement best describes a cause and it's effects that occur during the process of muscle contraction.
Muscle contraction can be explained by sliding filament theory.
1. Activation of muscles: the motor nerve generates an impulse to transfer signals from neurons to neuromuscular junction. This stimulates sarcoplasmic reticulum to release calcium into the muscle cells.
2.Contraction of muscles: calcium in the muscle cells binds with troponin causes actin and myosin to bind. Actin and myosin in the muscle binds and contract by utilizing ATP as a source of energy.
Answer:
hey love! so i actually have celiac so i know a lot about this haha! hope this helps!!
Following a gluten-free diet in the absence of celiac disease may be detrimental to health. Nutritional deficiences: Avoiding foods that contain gluten can lead to deficiencies in essential nutrients, including iron, calcium, fiber, folate, thiamin, riboflavin, and niacin.
Explanation:
In recent years, the gluten-free diet has become more of a fad than a medical necessity. ... The study concluded that more gluten consumption is associated with a lower risk of heart disease, suggesting that those who do not suffer from celiac disease or non-celiac gluten/wheat sensitivity should not avoid gluten. Though many health professionals suggest otherwise, it's safe to follow a gluten-free diet — even for people who don't necessarily need to do so. Cutting out wheat and other gluten-containing grains or products will not cause adverse health effects — as long as these products are replaced with nutritious foods.
