Answer:
B) nuclei of gland cells.
Explanation:
DNA carries the blueprint for the production of all the proteins including enzymes in human beings. Humans are eukaryotes and their DNA is present in the nucleus of their cells. All the cells that make the complex human body are derived from division in the zygote and therefore, are genetically identical and have the same DNA.
However, gene expression is regulated by the expression of specific genes in specific cells and at a different time of developmental stages. Amylase is the enzyme that digests starch in humans. Amylase is secreted by salivary glands. So, the nuclei of these glands would have genetic information for the synthesis of amylase.
Answer:
The definition of an organism is a creature such as a plant, animal or a single-celled life form, or something that has interdependent parts and that is being compared to a living creature. An example of an organism is a dog, person or bacteria.
Explanation:
I didn't really get what you were asking so there's the definition. :)
Rainfall can cause erosion both when the rain hits the surface of the Earth, called splash erosion, and when raindrops accumulate and flow like small streams. Rivers can create a significant amount of erosion over time. They break up particles along the river bottom and carry them downstream. One example of river erosion is the Grand Canyon which was formed by the Colorado River. Ocean waves can cause the coastline to erode. The shear energy and force of the waves causes pieces of rock and coastline to break off changing the coastline over time. Large floods can cause erosion to happen very quickly acting like powerful rivers.
Blood distribution is adjusted by a short-term neural control mechanism to meet specific demands. During working out, the hypothalamus signals for reduced vasomotor stimulation of the skin vessels. Blood moves into the capillary veins, and heat radiates from the skin to reduce body temperature.
<h3>Veins</h3>
All over your body, veins are blood vessels that collect blood with low oxygen content and send it back to your heart. Your circulatory system includes your veins. They cooperate with your heart, other blood vessels, and other organs to maintain blood flow. Most of your body's blood is stored in veins. Your veins actually contain around 75% of your blood. Veins have two basic functions. One function is to gather blood that is low in oxygen throughout your body and transport it back to your heart. The other function is to transport blood that is rich in oxygen from your lungs to your heart. Only during this process do veins transport oxygen-rich blood.
Why does venous return from the distal arm travels in the superficial veins and those veins tend to bulge superficially in a person who is working out?
