Purple loosestrife is an invasive plant that was brought to the United States in the 1800s. Which of the following describes the most likely long-term consequence of the introduction of purple loosestrife?

A. Herbivores will overpopulate due to an abundant food source.
B. Native plant populations will decrease as they are choked out by the purple loosestrife.
C. Purple loosestrife will begin to crossbreed with native plant species.
D. Air quality will improve as a result of the increased rate of photosynthesis.

Answers

Answer 1
The best answer is B) Native plant populations will decrease as they are choked out by the purple loosestrife.

Two results are likely when an invasive species, plant or animal, is introduced to a new population: that species will compete very well in the new environment or will not be successful. 

One possible result of the introduction of the purple looseleaf is that the species will do very will in its new environment, out-competing native plant species and thus choking them out of their natural environment. 
Answer 2

Out of all the answers the best one is B

Answers

The stripes are still considered a genetic mutation due to the fact that a cheetah's distinctive marking is their spots which is a genetic trait, and having stripes is abnormal for the species. Hope this helps!

The stripes are as yet considered a genetic mutation because of the way that a cheetah's unmistakable checking is their spots which is a hereditary quality, and having stripes is anomalous for the species.  

Further Explanation:  

Depiction of a cheetah:  

The cheetah is one of the most effortless individuals from the feline family, and one of only a handful couple of feline species which depends on speed rather than stealth when chasing. Cheetahs are in reality the quickest land warm blooded animals on Earth, arriving at velocities of 110-120 km/h.  

Genetic mutation:

A genetic mutation is a perpetual adjustment in the DNA arrangement that makes up a quality, with the end goal that the succession varies based on what is found in a great many people. Transformations run in size; they can influence anyplace from a solitary DNA building square (base pair) to a huge section of a chromosome that incorporates various qualities.  

Case of genetic mutation:

Some notable acquired genetic issue incorporate cystic fibrosis, sickle cell pallor, Tay Sachs infection, phenylketonuria and visual weakness, among numerous others.

Answers

chlorophyll is in chloroplasts and is why leaves are green. it helps absorb as much light energy as possible for photosynthesis.
Final answer:

Plants appear green due to chlorophyll, the main pigment in plants, reflecting green light while absorbing most other colors for photosynthesis.

Explanation:

Most plants appear green because chlorophyll, the primary pigment in plants, absorbs light most efficiently in the blue and red parts of the electromagnetic spectrum and less efficiently in the green part. Essentially, green light is reflected, not absorbed, by the plant, giving it a green appearance. This ability of chlorophyll to absorb light energy is vital for the process of photosynthesis wherein plants convert light energy, water, and carbon dioxide into oxygen and glucose.

What effect will an animals eating less during hibernation most likely have it maintenance of cellular homeostasis ?

Answers

Final answer:

Eating less food during hibernation helps animals conserve energy, rely on fat reserves, and minimize exposure to dangers.

Explanation:

During hibernation, animals experience a decrease in activity and metabolism, leading them to eat less food. This reduction in food intake has several effects on the maintenance of cellular homeostasis. First, it helps the animal conserve energy by reducing metabolic processes, such as protein synthesis and cell division. Second, it allows the animal to rely on stored fat reserves, which can be broken down and used as an energy source during hibernation. Finally, by reducing the need for food, hibernating animals can minimize the risk of exposure to predators or other dangers that may be present during winter months.

Name the 3 chemical products of the light reactions. which two get passed on to the calvin cycle? which one leaves the leaf?

Answers

ATP, NADP, and OXYGEN are the three chemical products of the light reaction in which the ATP and NADP get passed on to the Calvin Cycle and the OXYGEN is the one that leaves the leaf. Adenosine triphosphate or ATP is defined by the biology as the energy currency of life, Nicotinamide denine dinuleotide phosphate or NADP it is define as a coenzyme that occurs in many living cells, and Oxygen with the chemical symbol O is defined as odorless, colorless and a gaseous element constituting about one-fifth of the volume of the atmosphere and present in a combined state in nature.

The light-dependent reactions in photosynthesis produce ATP, NADPH, and oxygen. ATP and NADPH are passed to the Calvin cycle, and oxygen is released from the leaf.

Photosynthesis occurs in two main stages: the light-dependent reactions and the Calvin cycle.

The light-dependent reactions produce three primary chemical products: ATP, NADPH and Oxygen (O₂)

Among these, ATP and NADPH are passed on to the Calvin cycle, while oxygen is released as a waste product and leaves the leaf.

The chemical energy stored in ATP and NADPH, produced during the light reactions, is utilized in the Calvin cycle to drive the synthesis of glucose from carbon dioxide.The reactants are carbon dioxide (CO₂), ATP, and NADPH.The main product is glucose (C₆H₁₂O₆).

The gyri and sulci on the brain greatly increase the brain's surface area. how do you think this increase in surface area relates to improved brain function? 2. can you think of another organ in the human body that is shaped specifically to increase surface area? how does this organ's structure relate to its function in the body? (hint: think about those few bites of pancakes you ate in the opening paragraph.) 3. why do you think you created the frontal lobe of the cerebrum in the same color clay you used to create the three muscles of the face? 4. from the names alone, what do you think are the specific functions of the motor cortex and the sensory cortex of the brain? 5. what do you think the up and down arrows you carved into the spinal cord are meant to represent? 6. how do the central nervous system and the peripheral nervous system work together to control the body?

Answers

1) The way how this increase in surface area relates to improved brain function: The more surface area increased, the more chances of connection between neutrongs there are. Therefore, there is more possible learning (which  is improved function).

2) According to the hints, I would say that this question is about the small and large intestine. Keep in mind that the the intestines are needed to allow nutrients and water to diffuse into the body (during the process of expelling waste). Also,take into account that the greater the surface area, the faster the absorption will be processed.

3) You created the frontal lobe of the cerebrum in the same color clay you used to create the three muscles of the face because the main function of prefrontal cortex in the frontal lobe is to be responsible for expression of a personality. This will require the muscles that you put in the face of a model. 

4) The specific functions of the motor cortex are: To deal with motor skills (responsible for any type of movement).
The specific functions of the sensory cortex: To deals with sensory things (responsible for sensory perseption of things surrounding people).

5) The up and down arrows you carved into the spinal cord are meant to represent the movement of different nerve signals. These signals, which are slso called action potential, are coordinated movements of sodium and potassium ions that are psocessed across the nerve cell membranes.

6) The wayhow the central nervous system and the peripheral nervous system work together to control the body is shown here: the peripheral nervous system alerts communication to the central nervous system of things with the limbs and organs of a body.

Which part of an amino acid gives the molecule its characteristic chemical properties?

Answers

The side chain or R-group of an amino acid gives the molecule its characteristic chemical properties.

Amino acids are composed of a central carbon atom (the alpha carbon) bonded to an amino group (NH2), a carboxyl group (COOH), a hydrogen atom, and a variable side chain known as the R-group. It's the R-group that varies among different amino acids and determines their unique chemical properties. For example, amino acids with hydrophobic R-groups tend to be nonpolar and interact with other nonpolar molecules, while those with polar R-groups can form hydrogen bonds and interact with water and other polar substances. The specific characteristics of the R-group influence the amino acid's role in protein structure, function, and interactions.

Final answer:

The persistence of a pesticide is an important characteristic that refers to how long it will stay deadly in the environment. Persistent organic pollutants accumulate in the environment and can be toxic. The time required to kill all microbes within a sample at a given temperature is known as the D-value.

Explanation:

The subject of the question is Biology. One of the most important characteristics of a pesticide is its persistence, which refers to how long it will stay deadly in the environment. This is an important consideration because pesticides that are more persistent can stay in the environment for longer periods of time, potentially causing harm to organisms and ecosystems.

Persistent organic pollutants, or POPs, are a group of chemicals that are long-lasting and can accumulate in the environment. They tend to accumulate in higher trophic levels, such as in the fatty tissues of animals, and they are often toxic. Pesticides that are persistent organic pollutants can have long-term effects on ecosystems.

When it comes to microbes, the term used to describe the time required to kill all of the microbes within a sample at a given temperature is the D-value. This is the time it takes to reduce the population of microbes by one log (i.e., by 90%). It is an important factor to consider in processes such as sterilization and pasteurization.

Overall, understanding the persistence of pesticides, the accumulation of persistent organic pollutants, and the time required to kill microbes can help us assess the impact of chemicals on the environment and make informed decisions about their use.
