Kudzu, a plant native to eastern Asia was introduced into America in 1876. In 1935, kudzu was planted along southern roadways to control soil erosion. Adding a foot of vine a day in the spring and summer, kudzu quickly grew out of control. Why can introducing a new species to an existing ecosystem often be a disaster?
A. The new species can rapidly evolve into a dangerous subspecies that cannot be destroyed.
B. The new species can harm native organisms and damage the ecosystem.
C. The new species can create excess nutrients in the soil that can damage native species.
D. The new species can eventually become extinct.
Answer:
The best answer is B.
Explanation:
Since Kudzu is a foreign plant introducing it to the United States could damage the ecosystem since the ecosystem here is not "designed" to handle the Kudzu. This could cause a chain reaction along the food web and can potentialy wipe out local organisms.

What would happen if someone injected tapwater directly into their blood stream?
Answer:
cause your blood cells to become hypotonic possibly leading to death.
Answer:
The plasma will get diluted and it would cause blood cells to become hypotonic which could lead to death. But, the bigger issue is that you're using tap water which is not considered sterile and could lead to infections and other problems
Explanation:
in what cell organelle does photosynthesis occur?cellular respiration?
Photosynthesis occurs in chloroplasts and cellular respiration occurs in mitochondria.
What do you mean by cellular respiration?Cellular respiration is the process by which biological fuels are oxidised in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.
Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body.
Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion.

the golgi body interacts the most with which of these
A.nucleus
B.free ribosomes
C.Nucleolus
D.endoplasmic reticulum
When it comes to the processing and classification of proteins within the cell, the endoplasmic reticulum (ER) and the Golgi apparatus (also known as the Golgi body or Golgi complex) most often interact. Therefore, the correct option is D.
Before being delivered to their final cellular locations, proteins made by ribosomes on the rough endoplasmic reticulum (RER) are folded, packaged, and sorted in the Golgi apparatus. Modification, separation, and packaging of proteins and lipids for transport inside the cell or secretion outside the cell occurs in the Golgi apparatus, which is composed of flattened membrane sacs called cisternae. It takes up proteins and lipids from the ER, modifies them, and then puts them into vesicles for distribution to various cellular compartments or to be secreted from the cell.
Therefore, the correct option is D.

Which of the characteristics describe energy-carrier molecules?
can be coupled to energy-requiring reactions within a cell to help drive the reactions forward
accumulate in large quantities within a cell for long-term storage of energy
are quickly broken down once the molecules release their energy
include molecules, such as ATP, that contain high-energy chemical bonds
are generated when macromolecules, such as proteins, are broken down
Answer:
are quickly broken down once molecules release their energy
Explanation:
The characteristics of energy-carrier molecules are that they are quickly broken down once the molecules release their energy, which isoption. Energy-carrier molecules, like ATP, are quickly broken down into ADP (adenosine diphosphate) and inorganic phosphate (Pi) once they release their energy.
Energy-carrier molecules, such as ATP, store energy in high-energy chemical bonds. When these bonds are broken, energy is released and can be used for cellular processes.Energy-carrier molecules are not typically generated when macromolecules, such as proteins, are broken down. Energy carriers like ATP are produced through cellular respiration, primarily in processes such as glycolysis, the Krebs cycle, and oxidative phosphorylation.

Answer:
Rocky Surface D).
Explanation:
The inner planets consist of Mercury, Venus, Earth, and Mars. The inner planets all have a common surface composition, which is mainly solid rock. Although some of the inner planets have moons, only one has more than one, while the other two planets lack moons altogether.
None of the inner planets have rings.
The inner planets also tend to have thinner atmospheres. The general pattern for the inner planets is a thin atmosphere, few or no moons, and a surface composed of rock.
How would a scientist describe the illustrations showing the bones of a whale flipper and a bat
wing?
Vestigial structures because they will lose their function over time
Homologous structures because the structures are similar but have different functions
Analogous structures because they are similar but have different functions.
Embryonic structures because they show up before the species matures.
The bones of a whale flipper and a batwing are homo-logous structures because the structures are similar but have different functions. They have a common origin.
What are homo-logous structures?Homo-logous structures can be considered as similar structures that have the same evolutionary origin but may or not have the same function.
Homo-logous structures are always present in a common ancestor of the species that have these structures.
Conversely, analogous structures have the same function but they do not exhibit a common origin.

Describe the currents that form along the equator.
The currents that form along the equator are known as equatorial currents. These currents are driven by the trade winds and the Earth's rotation, creating a unique circulation pattern in the ocean.
There are two main equatorial currents:
Equatorial Counter Current: This current flows eastward along the equator, opposing the direction of the trade winds. North Equatorial Current and South Equatorial Current: These currents flow westward on either side of the equator.The equatorial currents play a significant role in redistributing heat across the ocean and influencing climate patterns.
Thus, the equatorial currents along the equator are dynamic and essential components of the global ocean circulation system, playing a crucial role in the Earth's climate system.
