Populations of organisms that have sigmoid growth curves limited by the carrying capacity are called

nasty-shy [4]

Populations of organisms that have sigmoid growth curves limited by the carrying capacity are called K-selected.

Species are divided into two selected species, R-selected species and K-selected species. K-selected species are also called K-strategist. These are the species whose populations vary at or near the carrying capacity (K) of the environment in which they live.

These species are commonly found in the roots of land plants or trees. In addition, arbuscular mycorrhizae is also a kind of fungus that are also found in the roots of the plants and this fungus is believed to improve the phosphorus uptake and water absorption of land plants.

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:

A A

a Aa Aa

All the offspring have flower located at axial position

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

What is the current predicted doubling time for the world population?

ollegr [7]

Answer: The current predicted doubling time is 61years which makes 50years in your option the nearest possible answer.

Explanation:The world's current (overall as well as natural) growth rate is about 1.14%, representing a doubling time of 61 years.

We can expect the world's population of 6.5 billion to become 13 billion by 2067 if current growth continues.
