Answer:

So, the sampling method is when you count the number of life forms in an area and then use that number to figure out the total number of those types of organisms that are in a larger area.

Explanation:

Hope this helped! have an awesome day!! :D

"In genetic modifications, DNA inserted can come from _____ ." any organism containing the DNA of interest only the same plasmid
liq [111]

Answer:

<h2> any organism containing the DNA of interest</h2>

Explanation:

  • Such type of process in which the modification of the genes of the organisms takes place is known as genetic modification and also called genetic manipulation or genetic engineering.
  • In such type of the process, the branch of biological science that is known as biotechnology is used.
  • In this mechanism, genes of interest are separated from the certain organism and then this gene of interest is inserted into the host organism and such type of DNA that is formed after the addition of foreign genes or DNA is called recombinant DNA.
  • Such type of DNA is used in the production of genetically modified organisms and some other fields for the benefit of human beings.

Explain the chemical process of transforming energy from glucose to atp through the process of cellular respiration
svetlana [45]

Explanation:

During respiration, the breakdown of glucose undergoes several steps in order to produce ATP, namely in glycolysis, the Kreb's cycle and oxidative phosphorylation.

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

  • Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
  • The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
  • The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Based on the definition of a watershed, how many different watersheds were there in your model? Explain how you determined this
cupoosta [38]

Answer:

Water shed is created when an area or land separates the water flowing to different rivers, basin and seas.

Explanation:

Water shed are of different types-

  1. Large water sheds-Contain well developed channel networks.
  2. Small water sheds-Contain dominant land phase.
  3. Urban watershed-It is dominated by building,roads,pavements.
  4. Agriculture water shed-
  5. Forest water shed-Evapotranspiration is the dominant component of the hydrologic cycle.
  6. Mountain water shed-mountain is the dominant component that separates the water flow.
  7. Desert water shed-Sand dunes sand mounds that are formed by blowing air causes separation of water flow.
  8. Coastal watershed-Coastal area may partly be urban and is dynamic contact with sea.The hydrology is influenced by tidal action.
