what is inertia ? write down the relation between mass and inertia?
Answer:
The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

how air pollution affects environment and living thing
Answer:
Air pollution is harmful to human beings and other living things. Breathing polluted air increases the risk of developing lung diseases such as asthma and lung cancer. Breathing bad air also increases the chances of dying from other diseases. Children are most likely to be affected by air pollution
Explanation:
They can increase the risk of heart and respiratory diseases, as well as lung cancer. Ozone is a major factor in causing asthma (or making it worse), and nitrogen dioxide and sulfur dioxide can also cause asthma, bronchial symptoms, lung inflammation and reduced lung function.

an organism that invades a region can have negative consequences and not region what kinds of shifts can take place?
Invasive species provoke significant damages in the structure of native ecosystems. They also cause economical and socio-cultural problems.
------------------------------------
When talking about dispersion we refer to the change in a species´ range or distribution area.
When a species move and establish in a new area out of their original distribution range, they might be considered exotic or invasive, according to their
reproductive rate, population growth, and interaction with native species.The introduction of invasive species has ecological, economic, socio-cultural consequences. Once an invasive species has been established, it overgrows. In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their establishment. They interact with native species by competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-. They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species. They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.
As they expand, they can also affect human in an economical manner and has socio-cultural effects. Many invasive species might cause crops loss by eating cultures. They attack farm animals. They affect buildings and other structures or ships by eating wood. They might even attack humans and cause health problems.

Describe the natural environment of the species in terms of abiotic and biotic factors,
Answer:
Abiotic and biotic factors make up an ecosystem. Abiotic factors are the non-living parts of an environment. These include things such as sunlight, temperature, wind, water, soil and naturally occurring events such as storms, fires and volcanic eruptions. Biotic factors are the living parts of an environment, such as plants, animals and micro-organisms.
Together, they are the biological factors that determine a species' success. Each of these factors impacts others, and a mix of both is necessary for an ecosystem to survive.

How does an
enzyme speed up a chemical
reaction?
Answer:
By lowering the activation energy
Explanation:
Enzymes are biological catalysts. Catalysts reduce the activation energy for reactions. The lower the activation energy for a reaction, the quicker the rate. Common enzymes convert shape when substrates unite. Enzymes lower the activation energy required to turn a reactant into a product. Consequently, an enzyme-catalyzed reaction pathway has a smaller energy activation to succeed ere the reaction can progress. Therefore, enzymes speed up reactions by lowering the activation energy.
What is genetics and how does it relate to DNA?

B)A pressure cooker valve opening to reduce the high pressure inside
C) A computer screen dimming or when the battery gets low
D) A thermostat switching on an air conditioner when the temperature gets too hot
Answer:
D) A thermostat switching on an air conditioner when the temperature gets too hot
Explanation:
All other answers choices are negative feedback.
hope this helped!
A thermostat switching on an air conditioner when the temperature gets too hot is an example of positive feedback. Option D is correct.
Positive feedback is a process in which a change in a system causes further changes in the same direction, leading to an ever-increasing effect. In the case of a thermostat, the increase in temperature causes the thermostat to switch on the air conditioner, which cools down the room. This cooling down causes the thermostat to switch off the air conditioner, which then allows the temperature to rise again. This cycle continues until the temperature reaches a desired level.
In negative feedback, a change in a system causes other changes in the opposite direction, leading to a return to the original state. For example, when a herd of buffalo runs away after one of them spots a lion, the other buffalo will also run away, which will reduce the number of buffalo in the herd that are in danger. This will eventually lead to the herd returning to its original state. Option D is correct.
