When the atoms involved in a covalent bond have the same electronegativity, what type of bond results?

Living organisms interact with one another in their natural environment in order to ensure that energy needed for their metabolic activities is obtained. To do this, each organism plays different or specific roles. The roles that every organism must fall into are as follows:

- Producers are groups of organisms that have the ability to synthesize their own food using light (photosynthesis) or chemicals (chemosynthesis). Examples are green plants, algae, some bacteria etc.

- Consumers- These are organisms that lack the ability to synthesize their own food and hence depend on other organisms for their energy source. Consumers can either be herbivores (eat plants) or carnivores (eat flesh) etc. Examples are all animals etc.

- Decomposers- These are organism that have the ability to breakdown dead organisms into organic matter, thereby, adding nutrients back to the soil. Examples are fungi, bacteria, earthworm etc.

Based on this explanation above, no organism will not fall into any of these three categories. Some can even occupy two roles.

The gene for flower position in pea plants exists as axial or terminal alleles. Given that axial is dominant to terminal, list a

____ [38]

Answer:

F1

A A

a Aa Aa

All the offspring have flower located at axial position

F2

A a

A AA Aa

a Aa aa

Three offspring with genotype i,e Aa, Aa and Aa will have flower located at axial position

Only offspring with genotype "aa" will have flower located at terminal position

Explanation:

Let the allele "A" represent the characteristics of axial position of flower

Let the allele "a" represent the characteristics of terminal position of flower

Given -

"A" is dominant over "a"

F1 generation -

Two parents with homozygous genotype for both A and a are crossed . The punnet square for the cross between "AA" and "aa" is as follows -

A A

a Aa Aa

Thus the genotype of offspring is "Aa"

Since, "A" is dominant over "a", all the offspring have flower located at axial position

F2 generation-

The cross between two parents having heterozygous genotype "Aa" will take place .

The punnet square for the cross between "Aa" and "Aa" is as follows -

A a

A AA Aa

a Aa aa

Three offspring with genotype i,e Aa, Aa and Aa will have flower located at axial position

Only offspring with genotype "aa" will have flower located at terminal position
