Is the tamarisk beetle an invasive species? Read the following passage, and use the evidence provided to determine whether or not they would be classified as invasive.
“Tamarisk trees were introduced to the U.S. as an ornamental shrub due to their pretty pink color and ability to provide erosion control. However, they were soon recognized as invasives due to their hoarding of light, water, and nutrients, drying out riparian areas. They also were outcompeting the plants that the Southwestern willow flycatcher nested in. As a result, the tamarisk beetle was introduced because they eat the tamarisk plant. They were extremely effective, except there was one caveat- the flycatcher birds had begun to use the tamarisk to nest in. So, protocols had to be adjusted to allow some tamarisk to remain; no beetles were released within 200 miles of any flycatcher nest, so the bird populations could continue to grow while the beetles continued to remove invasive tamarisk trees in other areas.”
(1 point)
Yes, the tamarisk beetle is invasive, because it is destroying Southwestern willow flycatcher habitat.
Yes, the tamarisk beetle is invasive, as it is not native to the United States.
No, the tamarisk beetle is not invasive, because it is only destroying the intended invasive plants.
No, the tamarisk beetle is not invasive, as they were purposefully introduced

Some cells ignore cell Cycle checkpoint and continue to grow and divide uncontrollably despite cellular or genetic damage. What disease may directly result from such behavior?
Answer:
Cancer is a collective name for many different diseases caused by uncontrolled cell division.
Explanation:
Cancer is the kind of disease that will result from uncontrollable cell division despite cellular or genetic damage.
What is the relation between cell cycle and cancer ?
The relationship between the cell cycle and cancer is intuitive on the surface: the cell cycle regulates cell proliferation, and cancer is a condition caused by uncontrolled cell proliferation. Fundamentally, all tumors allow for an excessive number of cells to exist.
Cells have a variety of methods that they can use to control cell division, fix DNA damage, and stop the growth of cancer. As a result, it is believed that the development of cancer occurs through a number of steps and requires the failure of several different mechanisms before a critical mass of malignant cells is reached.
The majority of malignancies develop specifically when cells have a variety of mutations (changes in DNA) that cause them to cycle more rapidly, evade internal and external restrictions on division, and prevent planned cell death.
Thus, uncontrollable cell growth indices to cancer.

- mass, - energy flow, - populations in ecology, - predator and prey relationships
The biomass pyramid shows the decline or steady decline in biomass from base to peak of each trophic level. Pyramids employed in ecological systems don't use fresh weight.
What is the role of biomass in ecological pyramids?The biomass that is produced by organisms at every trophic level can be measured using a biomass pyramid.
The bottom level of this pyramid is occupied by the producer, which are typically plants. Primary consumers come after the producers.
The total living biomass or organic matter present at various trophic levels in an ecosystem is represented by a biomass pyramid.
The mass of living things present at each trophic level in a given sample size is used to determine biomass. Calories per unit area or dry weight in grams are two ways to see it.

Answer:
Plant Guidance by Ecoregions
Ecoregion 9 – High Plains
Extending from the Panhandle south to the Pecos River, the High Plains have been described as a sea of waving grasslands. The 20 million acres of this region fills most of the “handle portion” of the state. It is a relatively high and level plateau of sandy to heavy, dark calcareous clay soils over an impervious layer of caliche. The winters here are the coldest in Texas, with the average annual temperature being only 59 degrees. Rainfall ranges from 21 inches in the east to about 12 inches in the west. Sun and wind rob the soil of even the meager water it receives from these rainfalls. Today, most of the High Plains is irrigated by the vast Ogallala formation.
Classified as mixed plain and short-grass prairie, vegetation in the High Plains varies – highly dependent on location. Hardlands or mixed lands, sandy lands or caliche lakes, all give rise to a very different plant community. Honey mesquite and yucca have invaded some areas that were characteristically free of trees and brush. Sand sage and shinnery oak have spread through most of the sandy lands.
Playa lakes play an essential role in this region, and they are the prime waterfowl wintering grounds for the North American Central Flyway.
The regions other name, “Llano Estacado” or “Staked Plains” is believed to refer to the first European settlers who drove stakes into the ground to help guide them across this featureless region. These early pioneers found a vast carpet of short grasses that were home to enormous herds of buffalo and pronghorn antelope. This was also the home of the Comanches.
The original character of the High Plains has been forever changed by the plow, however unique areas still remain including some scattered sand dunes cloaked with Harvard shin-oak, sandsage, and little bluestem. Tallgrass meadows can still be found waving in the breezes along the Canadian and Red Rivers. While few rivers actually cross the High Plains, these meager water sources along the Canadian and Red Rivers one sustained luxuriant growths of tall willows and cottonwoods. Russian olive and tamarisk, two introduced species from the Old World, now replace these native trees along the rivers, altering the natural habitat of kingbirds and phoebes. Grasses still provide cover and nesting habitats for myriads of other birds, and belts of trees planted in the 1930s provide shelter to an amazing diversity of wildlife. While the Gray Wolf and elk no longer occur on the High Plains, mountain lions, coyote, Red-tailed Hawk and swift fox now crown the food chain. While greatly reduced, scattered populations of Lesser Prairie-chicken still boom to announce the coming of spring across the region while flocks of Lark Buntings and Horned Larks ply the skies over this restless sea of grass.

The best explanation for the net movement of molecules is that Water is moving at equal rates both and out of the cell. So, the correct option is (C).
What are Different types of Solutions?
There are 3 types of solution. These are:
1. Hypertonic Solution
Hypertonic solutions are those in which the solute concentration is higher than in any other solution. For example, the internal solution of a cell in it.
If these cells are placed in a hypertonic solution, the movement of water outside the cell is greater than inside the cell.
2. Hypotonic Solution
Hypotonic solutions are those in which the concentration of the solute is less than that of the other solution.
If a cell is placed in a hypotonic solution, the movement of water inside the cell is greater than the movement outside the cell.
3. Isotonic Solution
Isotonic solutions are a type of solution whose strength is equal to that of another solution.
If a cell is placed in an isotonic solution, there is an equal rate of movement of water into and out of the cell.
For the above information, isotonic solution is used in the experiment because the movement of water in and out of the cell is the same.
Thus, the best explanation for the net movement of molecules is that Water is moving at equal rates both and out of the cell. So, the correct option is (C).

Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction has been the supreme quality of living things. The role capsid play in viral reproduction is that the capsid copies the host cell’s DNA.
There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved has been said to be sexual mode of reproduction and the process of reproduction in which only single parent has involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.

A comet has an orbit size of 3.5 AU & its orbit time is 6.54 years. T² = 42.875 years. What does R³ equal?
Answer:
42.875 AU is the answer.
Explanation:
Kepler's third law allows us to find the answer for the orbital radius of the comet's orbit and the relationship of the magnitudes are:
Orbital radio is a = 3.49 AU The ratio of the orbit to the cube to the period squared gives the Kepler constant.
Kepler studied the motion of bodies in the solar system creating mathematical relationships that describe their motion, Kepler's third law which is a direct application of Newton's second law to the orbit of the planets around the sun is
T² = K a³
Where T is the period of the orbit, a is the semi-major axis of the ellipse and K is a constant called Kepler's constant given by
K = [tex]\frac{4 \pi ^2 }{GM_s}[/tex] = 3 10⁻¹⁹ s²/m³
Where G is the constant of gravitation universes, M_s the mass of the Sun
In this case they indicate the size of the orbit tabulated a = 3.5 AU and the period T = 6.54 years, let's reduce the two magnitudes to the international system of measurements (SI)
T = 6.54 years [tex]( \frac{365 d}{1yr} ) ( \frac{24h}{1 d} ) ( \frac{3600s}{1 h} )[/tex] = 2.062 10⁸ s
Let's calculate the radius of the orbit
a = [tex]\sqrt[3]{\frac{ T^2 }{K} }[/tex]
a = [tex]\sqrt[3]{\frac{(2.062 \ 10^8 )^2 }{3 \ 10^{-19}} }[/tex]
a = [tex]\sqrt[3]{0.1417 \ 10^{36}}[/tex]
a = 0.5214 10¹² m
Let's reduce to astronomical units, which corresponds to the distance from the Sun to the earth
a = 0.5214 10¹² m ( [tex]\frac{1AU}{1.496 \ 10^{11}}[/tex] )
a = 3.49 AU
Let's observe that it is practically equal to the tabulated value.
The ratio of the orbit to the cube to the period squared gives the Kepler constant, which is practically invariant for all bodies in the solar system.
In conclusion using Kepler's third law we can find the radius of the comet's orbit and the relationship of the magnitudes are:
Orbital radio is a = 3.49 AU The ratio of the orbit to the cube to the period squared gives the Kepler constant
