An animal with no natural enemy is a ____________.

Answers

Answer:

predator or a.pex predator

An animal with no natural enemy is an apex predator. Apex predators are also known as top predators or alpha predators.

They are species that reside at the highest level of the food chain within their ecosystems. They have no natural predators and primarily feed on other animals. Apex predators play a critical role in maintaining the balance and functioning of their respective ecosystems.

These predators are often characterized by their exceptional hunting skills, agility, strength, and ability to control the populations of their prey. They exert top-down control on the food chain by keeping the populations of lower-level consumers and herbivores in check, which in turn has cascading effects on the entire ecosystem. Thus, apex predators have no natural enemies.

A student is collecting the gas given off from a plant in bright sunlight at a temperature of 27 degrees celeius. What gas is being made?

Answers

Answer:

Oxygen

Explanation:

Plants in the presence of sunlight (a major requirement) are capable of manufacturing their own food via the process of PHOTOSYNTHESIS. Photosynthesis combines carbon dioxide (from atmosphere) and water (from soil) to produce glucose (carbohydrate) and oxygen gas (as a waste product). The equation as follows:

6CO2 + 6H2O ➡ C6H12O6 + 602

According to this question, a student is collecting the gas given off from a plant in bright sunlight at a temperature of 27°C. The process carried out by the plant exposed to the bright light is PHOTOSYNTHESIS, hence, the gas given off is OXYGEN.

Which of the following is NOT true of a reaction that breaks a bond?
A. It creates low-energy products
B. It is what happens in cellular respiration
C. It is an endergonic reaction

Answers

Answer:

C

Explanation:

Endergonic reactions use energy to build bonds

Exergonic reactions release energy through breaking bonds

C.  It is an endergonic reaction.

Endergonic v/s Exergonic:

In the exergonic reaction, the reactants are at a higher free energy level than the products (reaction goes energetically downhill) while In the endergonic reaction reaction, the reactants are at a lower free energy level than the products (reaction goes energetically uphill). Endergonic reactions use energy to build bonds  while Exergonic reactions release energy through breaking bonds.When a bond breaks, it creates low-energy products.In cellular respiration, breaking of bond happens.

Therefore, the statement which is NOT true for a reaction that breaks  a bond is option C.
