Growth of the plumule does not occur until the cotyledons have grown above ground. This is epigeal germination. ... These seeds develop by the plumule growing up through the soil with the cotyledons remaining below the surface. This is known as hypogeal germination.
Answer:
In terms of genetic variation, allelic richness (A) estimated through rarefaction resulted in 1.6–3.0 mean alleles per colony, and no private alleles were found. Mean genetic diversity (HE) was 0.525 (SD = 0.11), with values ranging from 0.276 (SD = 0.25) to 0.618 (SD = 0.09).
Explanation:
Utah prairie dog (Cynomys parvidens), and Mexican prairie dog (Cynomys mexicanus)—all of which may be considered rare (Hoogland 2006a). After 200 years of shootings, poisonings, conversion of habitat, and more recently plague, prairie dog numbers are a fraction of what they once were. Two of the species (Utah and Mexican) are listed as threatened or endangered under the Endangered Species Act (ESA).
Answer:
During photosynthesis solar energy is transformed into chemical energy.
Explanation:
Photosynthesis is a process in which green plants prepare their own food with the help of sunlight, carbon di oxide and water. In this process, the sunlight,i.e the solar energy get trapped and converted into chemical energy. In photosynthesis, organic compounds and oxygen is being produced. Further, the organic compounds play the role of food to the green plats. During this process, ATP is also produced.
Answer:
mitosis
Explanation:
The zygote undergoes a process known as mitosis, in which it replicates its chromosomes (which carry each parent's DNA) and then divides, resulting in two identical cells. These cells are called totipotent and have the ability to develop into a new organism
Humans impact the physical environment in many ways overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
