based on the flow of energy and biomass in ecosystem, determine the rough proportion of producers and consumers needed in the ec
Mila [183]
The number of producers is more than consumers and top carnivores in ecosystem. for example:- in the food chain of grass--goat--man,atleast 90% of energy is pasted to other level and 10% will be stored at that level it self. 
        grass                 goat                   man
       50/100               40/80                30/60.
as we human beings depend on plants and animals for our food for our whole life we need atleast 100 numbers of small plants for one week.

Classify each statement as a description of glycolysis, glycogenesis, glycogenolysis, or gluconeogenesis.
loris [4]

Glycolysis is the breakdown of glucose where the final product is pyruvate, glycogenesis is the process of formation of glycogen and the product in first step is glucose-1-phosphate. Glycogenolysis is the process in which the initial reactant is glycogen, and gluconeogenesis is the formation of glucose from pyruvate.

<h3>What is glycogen?</h3>

Glycogen is a type of carbohydrate that is stored in the liver and gets converted into glucose in emergency situations.

It is formed by the process of glycogenesis and the first-step product is glucose-1-phosphate.

Glycolysis is the breakdown of glucose where the final product is pyruvate.

Glycogenolysis is the process in which have initial reactant glycogen and occurs when brain and muscle require immediate energy.

Gluconeogenesis is the formation of glucose from pyruvate.

Thus, these were the explanation for glycolysis, glycogenesis, glycogenolysis and gluconeogenesis.

A newly discovered animal reproduces slowly. It has only one offspring each time it reproduces. Which reproductive strategy does
Marizza181 [45]

Answer:

C: K Strategy

Explanation:

The best choice will be C- K strategy because this type of strategy involves greater investment from parents into their offspring. These organisms are mostly higher organisms which reproduce slowly and ensure the maximum survival of their offspring. They compete strongly with other organisms and invest more in their survival by producing fewer quality offspring that have more survival opportunities.

Example of K-selected species include  larger mammals (such as primates and horses), birds and larger plants. Unlike their opposite R-selected specie which produce large number of offspring, K selected specie are called in Equilibrium wile R-selected species are called as opportunistic.

Thank you!

Part II: For each of the genotypes below, determine what phenotypes would
Troyanec [42]

Answer:

4. Brown

5. Brown

6. Blue

7. Long

8. Long

9. Short

Explanation:

Dominant alleles are always expressed when they are present. Recessive alleles are masked by dominant alleles.

Therefore, two copies of a recessive allele are required to show the recessive trait. Either one or two copies of a dominant allele produces the dominant trait.

Therefore, for dominant brown eyes, BB or Bb gives brown eyes, bb gives blue eyes.

For recessive long tails, tt gives short tails, TT and Tt gibe long tails
