Describe the natural environment of the species in terms of abiotic and biotic factors,
Answers
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.
7. Explain why there is a difference in the amount of oxygen taken in at rest and during the vigorous activity, (2
Answers
Answer:
Physical exercise leads to an increase in the arteriovenous oxygen difference in all individuals. As exercise intensities increase, the muscles increase the amount of oxygen they extract from the blood, and this therefore results in further increases in a-vO2 diff.
Explanation:
There is a difference in the amount of oxygen intake during rest and vigorous activity due to the higher amount of energy required during vigorous activity.
What is aerobic respiration?The breakdown of glucose in the presence of oxygen to generate carbon dioxide water and energy in the form of ATP and heat energy is called aerobic respiration.
Aerobic respiration is a characteristic of higher animals because of a higher level of energy required by them. The process of aerobic respiration produces higher levels of energy compared to the process of anaerobic respiration which is a characteristic of lower organisms.
When a person is performing a vigorous activity, the energy requirement increases. This increases the process of cellular respiration which requires oxygen.
Therefore, when a person is performing vigorous activity their oxygen intake is higher compared to when they are at rest.

The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells. Inside, carbonic anhydrase converts carbon dioxide into carbonic acid (H2CO3), which is subsequently hydrolyzed into bicarbonate (HCO3−) and H+. The H+ ion binds to hemoglobin in red blood cells, and bicarbonate is transported out of the red blood cells in exchange for a chloride ion. This is called the chloride shift.
Bicarbonate leaves the red blood cells and enters the blood plasma. In the lungs, bicarbonate is transported back into the red blood cells in exchange for chloride. The H+ dissociates from hemoglobin and combines with bicarbonate to form carbonic acid with the help of carbonic anhydrase, which further catalyzes the reaction to convert carbonic acid back into carbon dioxide and water. The carbon dioxide is then expelled from the lungs.

what is inertia ? write down the relation between mass and inertia?
Answers
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.

Answer:
Explanation:
Here is a website that has a list of organic compounds that are not soluable in water, but the common examples are
https://www.chemistryscl.com/advancedlevel/organic/water-soluble-organic-compounds/main.html
"Alkane, alkene and alkyne belong to the hydrocarbon type. In hydrocarbons, there are only carbon - hydrogen bonds in the organic compound. So polarization is weak to make strong intermolecular forces between water molecules. Therefore, alkane , alkene and alkyne are not soluble in water."
"Benzene is not soluble in water because benzene cannot make strong intermolecular forces such as hydrogen bonds or dipole dipole interactions. "
The reason I am linking you to this website instead of telling you straight out of the gate, is to spark some investigative need into your brain so that maybe next time for the next thing in chemistry or biology you may not need to come back because of the previous knowledge you have. Anyways, I hope this helps you and reminder to stay curious.

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.
