1.) D- phloem is Bi-directional and can flow upward or downward
2.) C- it transports the water from the roots to the stems and leaves
3.) A- capillary action <span>is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity, so it can flow upward through the tissue
4.) B- It conducts the sugar and other metabolic materials downward from the leaves
5.) A- </span><span>The roots </span>have a type of cell called a root hair cell - these project out from the root into the soil. The water<span> absorbed by the root hair cells passes through the plant in xylem tubes, and eventually reaches the </span>leaves<span>.
6.) A- It transports </span> water<span> from roots to shoot and leaves, but it also transports some </span>nutrients. It is Uni-directional though and can only flow upward.
Hope this helps! Good luck
Answer: The correct option is c. red, green and blue.
Red, green and blue are primary colors. The theory of trichromatic theory is derived from the color mixing and the color matching explanations. According to the experiment in this theory, the individual person having normal vision of color requires three wavelengths of the primary colors to match with any other color in the visible spectrum. This led to finding of color vision which is based on the activities of three different receptors each having a different sensitivity of the peak. The three receptors are each sensitive towards colors red, blue and green respectively.
The answer is phagocytosis which is also known as cell eating. It is a process by which the living cells which are called phagocytes would ingest other cells. It might be an amoeba or a white blood cell. Hope this would help.
1. a wide variety of factors. heat, climate, weather, natural disasters that lower the population of prey animals, etc
2. well and example is this: it is getting hotter in Antarctica, causing the ice caps to melt. this change would make it harder for prey animals like penguins to find somewhere to live, thus making them easier food for predators. such as killer whales and polar bears.
3. the more trees we cut down to make room for buildings, for instance, causes many animals habitats to dissapear, the animals shortly after
1. They play dead when faced by a predator.
2. They travel in schools of about 12.
3. Males establish their dominance by having sword fights with their spines and showing off their bright colors.
