They release pollution into many environments.
They easily contract and spread diseases to other organisms.
Answer:
A
Explanation:
They often use up resources that other organisms need.
The reason of nonnative species a threat to biodiversity is because of using resources that other organisms need.
Reason why nonnative species a threat to biodiversity:It leads to various kinds of diseases. It acted like predators or parasites. It acted like a competitor or rivalry. It should be hybridizing with local species.Hence, The reason of nonnative species a threat to biodiversity is because of using resources that other organisms need.

Explain how our body systems work together to get oxygen into and around our body
PLS DONT COPY AND PASTE THE ANSWER FROM THE INTERNET
The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.
How Oxygen from the air is absorbed?Oxygen from the air is absorbed into the bloodstream through the lungs. When it reaches the lungs, the function of the cardiovascular system begins, since that is where the non-oxygenated blood is oxygenated and returns to the heart.
When in the cardiovascular system, the blood reaches the capillaries in the tissues, oxygen is released, which the cells use to produce energy. These cells release waste products, such as carbon dioxide and water, which are absorbed and transported by the blood.
O2 and CO2 are constantly circulating and passing from one medium to another, so much so that O2 passes, along with other gases, from the atmosphere to the airways, entering through the nostrils and driving through the larynx, trachea, source bronchi, terminal bronchioles, respiratory bronchioles, alveolar sacs and alveoli.
Therefore, The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.

How do the nutrients found in plants function in plant DNA? Is the function of plant DNA similar to human DNA?
Answer:
How do the nutrients found in plants function in plant DNA?
Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
Is the function of plant DNA similar to human DNA?
How much DNA do plants share with humans? Over 99%? ALL animals and plants share the same DNA which is basically a code of only 4 'letters' which code for the same amino acids from which all proteins are made.

l. A farming area developed a major locust problem. Swarms of locusts were destroying crops and the environment. A team of
scientists developed an infectious disease that would reduce the population of locusts What would be most important to find
out before producing and releasing the disease?
how a decreased number of locusts would affect other organisms
which species might eat the crops in the absence of locusts
how the disease can be used for other applications
O how quickly farmers would get to see the results
Answer: how a decreased number of locusts would affect other organisms.
Explanation:
When engaging in any action aimed at destroying large numbers of an organism as is the case here, there is always a need to check what impact it might have on the ecosystem at large.
This is why it is very important that the effect of a decreased number of locusts on other organisms is evaluated before such drastic action is taken. If it would lead to a situation where the ecosystem is destabilized, the consequences would be far reaching and very damaging.
How a decreased number of locusts would affect other organisms is the
most important to find out before producing the disease.
What is Population?This is referred to the number of organisms present in an area over a
specific period of time.
We were told that swarms of locusts destroyed the environment and
needed to be reduced through the creation of a disease. The effect the
decrease in locust has on other organisms has to be considered to ensure
the ecosystem is balanced and doesn't adversely affect others.

Which of the following are internal cellular conditions?

Answer: a
Explanation:
The following are internal cellular conditions :
A) temperature, pH, water concentration, salt concentration.
Temperature facilitates deciding what can input or depart the cellular and the way properly molecules observed inside the membrane can function. Temperatures that might be too excessive or too low can severely harm and, in the intense temperature ranges, kill the cellular via their impact at the cellular membrane.
Physiologically ordinary intracellular pH is maximum generally among 7.0 and 7.4, even though there may be variability among tissues (e.g., mammalian skeletal muscle has a tendency to have a pHi of 6.8–7.1). There is likewise a pH version throughout special organelles, that can span from round 4.5to 8.0.
Water concentration:
Water molecules flow into and out of the cell at an identical fee, so the length stays constant. then a cell. This method of water attention is better within the cell than outside. Thus, water flows out of them, inflicting them to shrivel or maybe die.
Salt concentration:
Increase of the way of life medium NaCl attention from a hundred and 20 mm to 220 mm ended in a reduced boom fee and a boom in the content material of ribonucleic acid (RNA), protein, and lipide phosphate consistent. Cell quantity becomes likewise increased.
