Answer:
This question is incomplete and lacks options, the whole question is:
Plant hormones serve as chemical messengers between cells and tissues. Auxin is a plant hormone that causes the cells on the shady side of a plant shoot to elongate. The response enabled by auxin is known as -
Options are:
A. geotropism
B. transpiration
C. phototropism
D. photosynthesis
The correct answer is c.
Explanation:
Phototropism is known as a natural and organic movement of a plant towards the light. This is due to the natural ability of a plant to change direction based on changes in lighting in the environment. But external stimulus is not enough. It must generate some changes inside the plant that make it react in this way: hormones. A hormone is a chemical substance produced in one tissue and transported to another, in which it exerts one or more highly specific effects.Auxins are members of a group of plant hormones that are more beneficial to stimulate plant growth, it is the responsible mechanism of the response to phototropism in plants, which tends to be concentrated in the region of the stem and leaves, when a plant lacks this, it can be noted since the bending towards the light source is little or no, that is, auxins make the cells of the stem growth region (rhizomes and stems) lengthen.
Answer:
a. sexual dimorphism was developing over time in these species.
Explanation:
Sexual dimorphism refers to the presence of observable distinct phenotypic differences between the males and females of the same species. In humans, adult males have a larger larynx which is responsible for their deep voice than females. Females have a relatively smaller larynx. Therefore, a trend toward decreasing larynx size in adult females and increasing larynx size in adult males in fossils represents the development of sexual dimorphism in these species.
Answer:
Reaction Range
Explanation:
Reaction Range defines the basic IQ of an individual based on both the Phenotype expressed by the Genotype of that organism as well as the external environmental factors.
Answer:
The three statements or tenets of the cell theory are: All living beings are made up of cells. Cell is the most basic unit of life. All cells must come from pre-existing cells.
