Answer:
O B. Introduce ladybugs to eat the aphids
Explanation:
In crop production, there are certain pests known to categorically affect a particular crop plant. Hence, there are ways devised to tackle this issue of pest attack on crops. One of those ways is the "BIOLOGICAL CONTROL METHOD".
The biological control method involves the use of natural enemies to combat pest organisms. The natural enemies are living organisms that prey on the so called pest organism. This is the case in this question, where a specific aphid is known to infest spinach, peppers, and tomatoes.
The farmer will employ biological control method in stopping these aphids by introducing ladybugs to eat the aphids.
Dissolved minerals in the ground water precipitate (crystallize) from water in the pore spaces forming mineral crusts on the sedimentary grains, gradually cementing the sediments, thus forming a rock.
Answer:
- The proteins in the chicken are broken down into amino acids, and the DNA in Amanda's cells uses those amino acids to build human proteins.
Explanation:
The body uses the protein taken by Amanda in the form of a chicken sandwich by breaking it down into the form of compounds called 'amino acids.' Amino acids are described as the substances that are responsible for the formation of proteins in the body. Thus, the DNA present in Amanda's body cells will use these amino acids to form human proteins. The longer chains of these amino acids help the body to ensure its proper structuring and functioning.
The regulation of the bodies internal environment is called homeostasis. And there are so many ways that affect homeostasis in the human body and to name three: first is the heat where we seat when we get too hot. Second, is the cold where we shiver when we get too cold and the third is the fluid intake where dehydration can kill.
All what the word tetravalent means is that carbon can form 4 chemical bonds, due to the fact that carbon has 4 unpaired valence electrons in its furthest shell, which can be used to bond to other atoms, to form linear and cyclic structures in organic compounds.
Tetravalent also tells us indirectly what the molecular geometry of the atom would be if bonded to those number of bonds, if 4, then it would be tetrahedral and have bond angles of 109.5.
