Answer: Trophic levels 1 and 2

Explanation:

Trophic levels pertains to organisms with similar feeding relationships in a biotic community.

There are usually five(5) trophic levels in a food chain.

Trophic level 1 - has primary producers (usually green plants)

Trophic level 2 - has herbivore (animals that feed on plants)

Trophic level 3 - has secondary consumers ( animals that feed on plants AND flesh e.g carnivores and omnivores)

Trophic level 4 - has tertiary consumers (animals that feed on secondary consumers e.g carnivores)

Trophic level 5 - has apex predators (animals that feed ONLY on flesh of other animals, and cannot be fed on)

Note, STRICT CARNIVORES can never occupy Trophic levels 1 and 2

NAD+ is a limiting factor in glycolysis. In the absence of ____________________ the conversion of (1) ____________________ to NA
scoray [572]

The correct options to fill in the gaps are:

  • ADP; NADH, and electron transport chain
  • alcohol fermentation; lactic acid fermentation; acetaldehyde; NADH; and NAD+

<h3>What is the role of NAD+ in glycolysis?</h3>

NAD+ serves as an electron acceptor in glycolysis. It accepts two electrons to become reduced to NADH + H+.

NAD+ is a limiting factor in glycolysis. In the absence of ADP, the conversion of NADH to NAD+ via the electron transport chain is prevented from happening.

In eukaryotes, the hydrogen atoms of the molecules mentioned in are transferred to certain organic molecules in one of two methods: alcohol fermentation as can occur in yeast and lactic acid fermentation as can occur in human cells. In the process mentioned in, the hydrogen atoms are passed to acetaldehyde, which is then converted to a molecule of ethanol. During this a molecule of NADH is oxidized to a molecule of NAD+, which allows glycolysis to continue on.

In conclusion, NAD+ concentration is limiting to glycolysis.

Which is the most highly sensitive time within the developing embryo for the risk of malformation related to environmental terat
Mashutka [201]

The most highly sensitive time within the developing embryo for the risk of malformation related to environmental teratogens is cleft palate at 8 weeks gestation. It is an opening in the roof of the mouth.

A teratogen is any substance and/or physical agent that may cause an irreversible abnormality in the structure of the developing embryo or fetus (e.g., classical pesticides such as DDT).

Cleft palate is a malformation mainly caused by mutagenic agents (teratogens) during pregnancy, which affects approximately one (1) of 650 births.

A cleft palate is a malformation that occurs when the two plates of the skull that form the roof of the mouth cannot be completely joined.

Alex777 [14]

Answer:

Movement of RNA molecules from the nucleus to cytoplasm.

Explanation:

Cytoskeleton are as important for cell as skeleton for us. It perform various functions for the cell such as;

  • Maitain the cell shape.
  • Provide movement to cell.
  • Provide movement for organelles
  • Help in cell divsion.

The Cytoskeleton is made up of protein and three type of fibers.

  • Microfilament
  • Intermediate filament
  • Microtubules
