A teacher asked each student in the class to make a model demonstrating the importance of solar energy for life on Earth. Which
model should a student make? A. A model of the electromagnetic spectrum
B. A model of a local food web
C. A model of the water cycle
D. A model of a mitochondrial matrix
The student should make a model of a local food web describing the importance of solar energy for the life on earth. This is because of the fact that solar energy is the basic source of energy for a food web. A food chain is a linear sequence of transfer of food and energy when one organism is consumed by another organism. A food web is a interconnection of two or more food chains. The food chain at the initial level includes producers which includes all photosynthesizing organisms like plants which captures the light energy from sun to produce their food. The plants are consumed by many organisms on earth. Therefore, food web model will demonstrate the role and importance of sun for existence of life on earth.
True. A protein becomes functional only when it reaches its tertiary shape (3D). It is not necessary for the protein to reach the quaternary stage, but that is just a more complex functioning protein. It really is just two tertiary merged together. Example is red blood cells.
In aquatic plants, water passes among the tissues and provides the medium for gas exchange. In terrestrial plants, air enters the tissues, and the gases diffuse into the moisture bathing the internal cells.
Flowers are living plants that grow if they have water and sun 2. without a lot of sun the flower will not be able to grow as tall and properly 3. flowers have a certain part that the bees collect to there hive in order to keep there colony growing 1.cones have a certain shape that make them easier to identify them from other parts of nature 2. Pine cones only come from pine trees, although all conifers produce cones. 3. Gymnosperms are a group of plants who have naked seeds, not enclosed in an ovary. 1. spores may consist of one or several cells (but do not contain an embryo) and are produced in large numbers 2. Some germinate rapidly, others 'rest', surviving unfavorable environmental conditions. 3.Spores are formed by ferns, horsetails, mosses, fungi and bacteria.
