The claim that most crabgrass preventers are administered in the early spring is accurate.
<h3>What eliminates crabgrass most quickly?</h3>
Pre-emergence herbicide is your finest tool for killing weeds like crabgrass (also called crabgrass preventer). Apply it before the crabgrass seeds begin to sprout in the spring. The granular herbicide functions by forming a chemical barrier on the soil's surface.
<h3>Is crabgrass removal worth the effort?</h3>
The unsightly, clumpy weed crabgrass will quickly take over your yard. Not only is it unattractive, but it also harms the health of your lawn, which is another incentive to get rid of it. Your turf will be overrun by crabgrass, which will keep your lawn from getting the nutrients it requires to produce healthy grass.

Answer:
c) 3
Explanation:
Cellular respiration includes following 3 processes:
1) Glycolysis
2) Citric acid cycle or TCA or Kreb's cycle
3) Electron Transport Chain (ETC)
In glycolysis, a 3 carbon compound known as pyruvate is produced from glucose. Each glucose molecule produces 2 pyruvate molecules. Each pyruvate molecule then enters a complex known as Pyruvate dehydrogenase complex wherein the pyruvate molecule further undergoes oxidative decarboxylation to produce a 2 carbon compound known as Acetyl-CoA.
.
The Acetyl-CoA then enters citric acid cycle or TCA or Kreb's cycle wherein this Acetyl-CoA and oxaloacetate are oxidized to produce CO₂ molecules in eight steps. Each glucose molecule is capable of producing six CO₂ after the completion of citric acid cycle. Since one glucose molecule produces 2 pyruvate molecules then it means <u>a pyruvate molecule will be able to produce three CO₂.</u>
This would be an example of overproduction. The frog lays thousands of eggs, which is more than it needs, or would need in perfect conditions.
The answer is Arachnids.
Crustaceans, Insects, and Arachnids belong to the phylum Arthropoda.
Of mentioned characteristics, most of the Insects have both wings and antennae. Remember all butterfly, bees, beetles, etc. Crustaceans (crabs, lobsters, shrimp, etc) have antennae, but they have no wings.
Thus, the only group of the mentioned that shows <span>neither wings nor antennae is Arachnids. Arachnids include scorpions, spiders, ticks, etc. and as it is known, these groups have neither </span><span>wings nor antennae.</span>
Answer
The three metabolic pathways that make up aerobic respiration are really all parts of one larger pathway because the products of early pathways (like NADH) become <u>utilize</u> in the last one.
Explanation
Aerobic respiration is that type of respiration in which glucose molecule is broken down into CO2 and H2O in the presence of oxygen and 36 or 38 ATP molecules are produced.
Aerobic respiration complete in four main steps:
1. Glycolysis
In this step glucose is broken down into 2 molecules of pyruvate acid along with the production of 2 ATP molecules and 2NADH.
2. Oxidation of pyruvate
In this step pyruvate are oxidized in the presence of co-enzyme A to become Acetyl Co-enzyme A. Again 2NADH are formed in this step.
3. Kreb Cycle
It occus in mitochondria. Here acetyle coenzyme A enter Carbon fixation, reduction and regeneration phase. In this cycle 6 NADH, 2FADH2 and 2ATP are formed.
4. Electron transport chain
All NADH that are produced in above steps get oxidize and help in the production of ATP along with the release of electron and proton that help in the formation of water.
