How do naturally occurring hormones affect plants? they ripen fruits, prevent plants from being eaten by insects, and plants collect water from soil. they start lateral leaf growth, plants collect water from soil, and speed up the growth of plant cells. they keep buds inactive in winter, speed up the growth of plant cells, and ripen fruits. they speed up the growth of plant cells, ripen fruits, and prevent plants from being eaten by insects.

I would go with D if I were you. I believe the hormones include gibberellin and ethylene.

Answer from: jake2920

They keep buds inactive in winter, speed up the growth of plant cells, and ripen fruits.

Explanation:

Plant hormones or phytohormones are substances produced by plants that act in the regulation of their development and growth. The function of hormones is to act as "chemical messengers" between cells, tissues and organs of higher plants.

The hormones act in specific places, in order to trigger an action. This action is varied, since each hormone has a specific and particular function, but if we can summarize the functions of the hormones, we can mention that they keep the buds inactive in winter, accelerate the growth of plant cells and ripen the fruits.

Answer from: Quest

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

Answer from: Quest

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
