Answer:
The correct answer is C) arachnoid mater.
Explanation:
Arachnoid mater, along with pia mater and dura mater, form the <u>meninges</u>, a very thick membrane that protects the brain and the spinal cord. The arachnoid mater is in the middle of the other two layers and it is very important since it holds the <u>cerebrospinal fluid (CSF)</u> in its interior. Arachnoid mater has finger-like projections that enter the dural venous sinuses and are called <u>arachnoid villi</u>. These villi are responsible for the diffusion of CSF into the blood.
The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. ... Or, igneous rock can form above ground, where the magma cools quickly.
The Tectonic Cycle is the process in which tectonic plates are created at rift zones where molten material pushes plates apart and destroyed at subduction zones as oceanic plates descend into the mantle. But only oceanic plates are subducted.
The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Ice and snow can sublimate directly into water vapor. ... Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff.
The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food. Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration
The nitrogen cycle involves three major steps: nitrogen fixation, nitrification, and denitrification. It is a cycle within the biosphere which involves the atmosphere, hydrosphere, and lithosphere. ... Instead, they depend on a process known as nitrogen fixation.
Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.
Answer:
D. Sami had low birth weight as a lamb but quickly grew into a large sheep.
Explanation:
The Sami lamb is an example of culled because it has the characteristics of quick growth. Culling is the process of separating organisms from a group of same type of organisms due to presence of desired or undesired characteristics. Sami sheep has a unique characteristic of having less weight at time of birth but having quick growth features that make to gain more weight and become large sheep so this sheep is removed from the population for its good traits.
Answer:
During the G1 phase, cells synthesize and grow mRNA and proteins for DNA synthesis.
Explanation:
The ATP molecule is composed of three components. At the centre is a sugar molecule, ribose (the same sugar that forms the basis of RNA). Attached to one side of this is a base (a group consisting of linked rings of carbon and nitrogen atoms); in this case the base is adenine. The other side of the sugar is attached to a string of phosphate groups. These phosphates are the key to the activity of ATP.
