Neurons typically communicate using ___________ signals to communicate within a neuron.
Insects have a distinct set of characteristics which all must have if they are insects. They must have three pairs of legs (even though sometimes they may appear different as larvae, such as caterpillars), a set of mouth parts, and a head, thorax, and abdomen.
Question: Which pituitary hormone causes liver cells to release somatomedins that increase the rate of uptake of amino acids by cells such as skeletal muscle fibers?
follicle-stimulating hormone
prolactin
thyroid-stimulating hormone
growth hormone
Answer:
growth hormone
Explanation:
Somatomedins are growth factors. The growth hormone makes the cells such as liver cells, skeletal muscles, bones, etc. to secrete the somatomedins. The somatomedins from the liver enter the bloodstream to reach the target cells. The somatomedins make the skeletal muscles, bones, etc. to absorb amino acids into the cells so as to facilitate protein synthesis. This growth factor also downregulates the breakdown of proteins. This is how growth hormone triggers the growth of muscles and soft tissues.
Answer:
Besides storing genetic information, nucleic acids helps in
Understanding diseases
Creation of proteins
Transmission of information
Explanation:
Understanding diseases
Knowledge about the nucleic acids and their mechanism of action helps in understanding the causes of a disease and the possible cure for the disease. A genetic disease is caused when there is a faulty gene, which is made up of nucleic acids, is present in the genome. These genes will make faulty RNA's which will result in the establishment of faulty proteins. Hence, by having understanding about nucleic acids, diseases can be studies and cured.
Creation of proteins
The information from the DNA is coded by the mRNA which is used to make proteins.
Transmission of information
Apart from storing information, the nucleic acids such as the DNA are also involved in the transmission of information.
Answer:
<em>The correct option is A. X, because organism X has the same role as the grasshopper</em>
Explanation:
In a food chain or a food web, a primary producer can be described as an organism which feeds on producers. The producers, in this case, are the corn stalks. Grasshoppers are primary consumers in this food web because they feed on the corn stalks. X is also a primary producer, just like grasshopper, because it feeds on the corn stalks which are the producers. Hence, option A is correct.
