if a horticulturist breeding gardenias succeeds in having a single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants?

Answers

Answer 1
Answer: The answer is to clone a plant asexually.

Cloning occurs naturally in some plants. Plants can clone themselves by asexual reproduction and, thus, produce identical copies of themselves. In asexual reproduction, there only one parent is necessary. There is no gamete fusion, no mixing of genetic information, so the offspring is genetically identical. So, after a horticulturist succeeds in breeding gardenias and wants to keep its line, it should clone it asexually. That way a particularly desirable set of traits will pass to all offspring.

Kevin is constructing an explanation of the importance of freshwater ecosystems. Which of these statements would be MOST USEFUL to include in the explanation?

Answers

You seem to have forgotten to include the statements we are supposed to select from. However I still wish you good luck !

Final answer:

Freshwater ecosystems, constituting a mere 1.8 percent of Earth's surface, are characterized by their biodiversity and the crucial ecosystem services they offer, including provision of drinking water, sanitation, and industrial uses. They house different zones due to varying abiotic factors like temperature and light penetration, with each zone inhabited by species adapted to these conditions. They are intrinsic to the well-being of terrestrial biomes, linked through various abiotic and biotic factors.

Explanation:

Freshwater ecosystems are of immense importance due to their rarity, diversity, and functionality. They encompass only 1.8 percent of the Earth's surface, including lakes, rivers, streams, and springs. These ecosystems are incredibly biodiverse, supporting a wide variety of species such as fish, amphibians, reptiles, insects, phytoplankton, fungi, and bacteria.

Humans are heavily reliant on these freshwater biomes as they provide indispensable ecosystem services. They supply fresh drinking water, assist in crop irrigation, provide sanitation facilities, recreation spaces, and serve various industrial purposes. Conservation of these freshwater ecosystems is crucial for the preservation of terrestrial biomes, as they are interlinked through abiotic and biotic factors.

Temperature, light penetration, and water movements are key abiotic factors influencing these ecosystems. The structural compositions of aquatic systems are largely shaped by density and temperature. Such factors delineate different zones within these systems, each housing organisms adapted to specific conditions.

The lion's scientific name is Panthera leo. The leopard's scientific name is Panthera pardus . The tiger's is Panthera tigris. Which statement is true?A)
All 3 animals share a genus.
B)
All 3 animals share a species.
Eliminate
C)
The 3 animals are genetically identical.
D)
The 3 animals share no genetic information.

Answers

Answer: The correct answer is A) All 3 animals share a genus.

According to the binomial nomenclature, two terms are used for giving a scientific name to an organism belonging to a particular species. In this nomenclature, first term depicts the Genus and the second term depicts the species to which that organism belongs to.

As per the scientific names, Lion, Tiger, and Leopard belong to the same genus that is Panthera.

Thus, A) is the right answer.
A) All 3 animals share a genus. Panthera is the lion, leopard and tiger's genus; the second word in their scientific names are the species name. These animals are under the Family Felidae.
