Number of covalent bonds by an atom is equal to number of unpaired electrons.

<h3><u>Explanation:</u></h3>

Valency of an atom is defined as the combining capacity of an atom. Valence electrons are defined as the number of electrons in the outermost shell of an atom.

Now for an atom, when more than one electrons are present, then  they often forms a pair. Like for example, if there are 7 valence electrons, 6 get as pairs and only one electron is unpaired. So this is why the halogens like fluorine, chlorine etc has the Valency of 1. For oxygen, 4 valence electrons become paired. And rest 2 electrons form 2 covalent bonds.

Brums [2.3K]

Answer: Lipids.

Explanation:

The large carbon -hydrogen bonds(C-H) in chains of lipids makes them ideal storage of energy.

T<u>he more C-H bonds breakage, the higher protons availability from Citric acid cycle NADH and FADH2  and hydrogen atom splitting (to protons and electrons) for  the electron transport chains (ETC</u>), and therefore the higher proton pumps for  more ATP's synthesis in the mitochondria matrix.  

In addition large number of electrons  surrounding carbon atom in fatty acids than other food molecule is added factor.  The transfer of these electrons to oxygen during oxidation of fatty acids releases large amount of energy (9 kilo calorie) into the cells,  more than other food substances

The image shows a bean-shaped bacterium with long tail-like projections streaming from it.
Leto [7]
I'd also say that the morphology presented in this picture is filamentous.
The reason for my believing this is that filamentous morphology concerns long visible chains, threads, or filaments, which you can see in the image.

bazaltina [42]

B) The grass height was the dependent variable.

E) Intermediate numbers of insects had the greatest positive impact on grass growth.

<h3>How insects affect the plant growth?</h3>

The grass height was the dependent variable because it depends on the nitrogenous waste of insects and presence of water. The numbers of insects had the greatest positive impact on grass growth because they provides nutrients to plant in the form of nitrogenous water so we can conclude that option B and E are the correct options.
