Answer: They may be wind blown, rain splashed, carried by animals, or moved in soil or water. Almost all short-distance spread is through these natural dispersal mechanisms. In their home territory, short distance spread is rarely a problem because the resident plants and animals have evolved to coexist more or less peaceably.
Explanation:
Humans can help in the spread of invasive species.
What is an invasive species?It is a species that is not naturally present in an area ("not native") and when introduced in that area disturbs the ecosystem.For example, Eichhornia crassipes, cane toad, etc.How can human spread the invasive species?Humans can help in the spread of invasive species:
A species is introduced due to its beauty - because of its beautiful flowers and leaf shapes, the water hyacinth was brought to India.It is a contaminant of a species that is introduced - Parthenium is thought to have arrived in India as a contamination in PL 480 wheat from the United States.They may be brought accidentally- Zebra mussels arrived in North America's Great Lakes by accident, clinging to big ships.To control the population of other species - Small Indian mongooses were introduced with the goal of controlling rats that were ruining the sugarcane crop.To learn more about species, invasive species, population and ecosystem here,

How is cell division different in prokaryotes and eukaryotes
Answer:
Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other cell structures. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles.
Explanation:
Answer:
Prokaryotes have fewer cells structures, have no nucleus, and have a singular chromosome. Eukaryotes, however, have multiple chromosomes that contain a nucleus, cell structures, and many organelles.

Which statements describe hormones in plants? Check all that apply.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Hormones help buds form and grow in the winter.
Auxin is the only hormone involved in plant development.
(i know that the first 4 are not right and neither are A, B, and D (1, 2, 4)
Answer:
The correct statements are: 1, 2, and 3.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Explanation:
Plant hormones such as Auxins perform various roles and helps in the growth and development of the plants. Cutting the main stem of the plant stimulates the auxin hormone and which stimulates the lateral elongation growth of the leaf growth.
Some tropisms are controlled by the hormones such as phototropism by auxin as a high concentration area of the auxin causes cell growth in a particular area and the concentration of auxin is stimulated by light.

Based on one of the four scenarios below, create an explanation for how Natural selection works, incorporating all of the 5 concepts that contribute to it.
1. Galapgos Darwin's Finches
2. Caribbean Anoles
3. Giraffe lab
4. In a field that is mostly green because of regular rain, the coat color of the mice species that lives there is mostly dark colors. Over a period of 10 years, there is a drought, and the grass has a lot more dead material, making the field have a much lighter over all color. What happens to the population of mice (coat colors) and why?
5. Make up your own scenario (tell me it) and then describe how natural selection would take place with changes.
Answer:
Population of mice having dark coat colors decreases by changing of features of natural selection.
Explanation:
The population of mice having dark coat colors decreases if the field has light colour due to drought conditions because they are vulnerable to their predators and natural selection. In green field, dark colour mice can't be seen by the predators that will leads to increase their population while on the other hand, if there is drought condition it will leads to increase the population of light colour mice because they can't be seen by predators and decreases the population of dark colour mice due to vulnerability to their predators. Food type availability to the organisms due to environmental conditions lead to natural selection of that organisms which can feed on that food type.

For a circular or square patch of habitat, the ratio of edge habitat to interior habitat __________ as the size of the patch decreases. View Available Hint(s) For a circular or square patch of habitat, the ratio of edge habitat to interior habitat __________ as the size of the patch decreases. decreases increases in square patches and decreases in circular patches increases remains unchanged increases in circular patches and decreases in square patches
Answer:
increases
Explanation:
Habitat is defined as a particular environment where a group of organisms normally lives. Some examples of habitat include, among others, forests, deserts, lakes, grasslands, etc. Moreover, an edge habitat refers to a habitat area that is in contact with another. This part of the habitat has ecological importance because it is used by many species in order to find food, refuge and rest. In the question above, it is expected that a greater number of smaller habitats increase edge habitat surface area when compared to the interior habitat area. The ratio between the edge habitat surface area and total habitat area may have a huge impact on entire ecosystems.

Which of the following is required in order for homeostasis to be maintained?
Select one:
There should be a constant input of stimuli to receptors so that internal conditions remain constant.
Passage of materials across cell membranes need to occur at a continuously rapid rate.
An organism should be able to move to a new environment when conditions change.
An organism should have an internal environment that differs from its external environment.
I would say B because all cell membranes need to maintain function

Cell division is not only for generating copy of DNA . Why ?
Answer:
sorry don't know sorry
Explanation:
ok
Answer: During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two "daughter" cells that inherit the same genetic information. ... Healthy cells can perform DNA replication with almost absolute accuracy most of the time.

The hypothalamus is the link between the nervous system and the endocrine system. The pituitary gland is called the master gland because it influences the release of hormones by other glands in the endocrine system, malfunctioning of which releases growth hormone, which can lead to gigantism.
What is Pituitary gland?The pituitary gland is defined as a small, pea-sized endocrine gland located at the base of your brain below the hypothalamus that releases several important hormones and controls the function of many other endocrine system glands.
There are four hormones which is secreted by the anterior pituitary gland that control the functions of other endocrine glands where these hormones include thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormones (LH). The pituitary gland is called the master gland.
Thus, the hypothalamus is the link between the nervous system and the endocrine system while the pituitary gland is called the master gland
