Since the hemlock and spruce trees are old, they are K-strategists. K-selected species, or K-strategists, are species that produce only a few offspring that live for a long time. r-selected species, or r-strategists, on the other hand are able to produce more offspring which survive for a shorter period of time.
Answer:
there are more electrons than protons
Explanation:
Answer:
The correct answer is vertebral column and cranium
Explanation:
Vertebrates are the animals that are characterized by having backbone or vertebral column and apart from the vertebral column they also have a bony skull. Skull and vertebral column protect the brain and spinal cord in vertebrates.
Vertebrata is a subphylum under phylum Chordata and clade Craniata so vertebrates have both cranium and vertebral column. In vertebrates, notochord is present in the embryonic stage and is replaced by vertebral column in adults.
Animals that comes under the Vertebrata are fishes, mammals, reptiles, amphibians, and birds. So the correct answer is B and C.
Answer:
DNA extraction is a routine procedure used to isolate DNA from the nucleus of cells. When an ice-cold alcohol is added to a solution of DNA, the DNA precipitates out of solution. If there is enough DNA in the solution, you will see a stringy white mass.
Explanation:
Answer:
a.glycolysis d.acetyl CoA b.citric acid cycle e.electron transport chain
Explanation:
Cellular respiration is set of metabolic processes that occur within the cell in order to produce usable energy (ATP) from the nutrients (food). It can be divided into four main stages:
- Glycolysis-anareobic process in which glucose is broken down and it occurs in the cytoplasm. Products of glycolysis are 2 molecules of pyruvate and 2 molecules of ATP.
- Transition- Pyruvate form the glycolysis is transported into the mitochondria, where it is converted to a molecule Acetyl CoA used for further breakdown
- Citric acid cycle or Krebs cycle- aerobic process that occurs in the mitochondria matrix in which 4 molecules of ATP, and NADH are produced
- Electron transport chain-set of reactions that occur within the cristae of mitochondria. NADH and electrons are passed through electron transport chain to result in the production of ATP (32 ATPs for every glucose).
