<u>Answer</u> :- Step 1 Receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment or from inside your body.
Step 2 The central nervous system processes information received from the peripheral nervous system.
Step 3 The central nervous system sends out the processed information to the peripheral nervous system.
Step 4 The peripheral nervous system sends a message to the body part that needs to respond so you can react appropriately to the stimulus.
<u>Explanation</u>:-
- There are two different parts of the nervous sytem-the peripheral nervous system (PNS) and the central nervous sytem (CNS).
- The <em>CNS</em> consists of the brain and the spinal cord .
- The <em>PNS</em> consists of all the nerves that lie outside the CNS.
- The main function of the PNS is to gather information from the <em>sensory receptors</em> located in our body and convey this information to the central nervous system.
- The CNS collects this information from the PNS and then interprets it. The interpreted information is then relayed back to the body parts via the PNS to perform the appropriate action.
The answer is; prokaryotes are the earliest life forms
Glycolysis was the earliest energy harvesting pathway in early living organisms. Glycolysis does not require oxygen attribute to the early condition of the earth where its atmosphere was majorly comprised of carbon dioxide. It is only after the great oxygenation event that life evolved the oxidative phosphorylation process.
Answer:
12 : 3 : 1
Explanation:
According to Mendel's principles, a dihybrid cross between two heterozygous summer squash parents (WwGg X WwGg) should yield offsprings, 12 with white, 3 with yellow and 1 with green color phenotype. The classic Mendelian phenotypic ratio for dihybrid cross is 9:3:3:1. In this case, genotypes W- G- and W- gg produce white color phenotype. This is because we have 12: 3: 1 phenotypic ratio in which the alleles of two different genes assort independently into gametes.
<em>Dihybrid cross for heterozygous summer squash:</em>
WG Wg wG wg
WG WWGG WWGg WwGG WwGg
Wg WWGg WWgg WwGg Wwgg
wG WwGG WwGg wwGG wwGg
wg WwGg Wwgg wwGg wwgg
Genotypes:
W-G- and W- gg = white = 12
ww G- = yellow = 3
ww gg = green = 1
