Answer:
The correct answer will be- non-living.
Explanation:
The rust is a chemical compound formed through a process called rusting by the oxidation of iron in the presence of air and water.
The formation of rust is a chemical process or a metabolic process which leads to the corrosion of iron and iron erodes away or rust eats the iron. It is not considered a living reaction as it lacks other features of living beings like not takes place in a cell as well not a heredity feature.
Thus, non-living is the correct answer
Rust eating a hole in a metal bucket is a nonliving process, as the answer to the question indicates. Iron, an element present in nature, is oxidised to make rust.
When iron is exposed to oxygen and moisture, it is created. Rust is not a living thing and cannot move, develop, or reproduce on its own. It is only a type of iron that is lifeless. A chemical interaction between the metal and oxygen causes rust to chew a hole in a metal bucket.
Rust is the result of the metal's reaction with oxygen to produce iron oxide. There is no need for a living thing for this response to take place because it is not alive. It is only a nonliving chemical process.

B. Internal respiration occurs.
C. Ribs and diaphragm muscles contract.
D. Inspiration occurs.
Answer:
The correct answer is option A.
Explanation:
Breathing is the exchange of air through the involved passages in between the atmosphere and the lungs. Inspiration is a process where we take air into the lungs from the atmosphere also known as inhalation.
Expiration is releasing air out of the lungs to the atmosphere. In expiration, the diaphragm relaxation and elastic recoil of tissue decrease the thoracic volume of lungs. That results in an increase the intraalveolar pressure in the lungs.
Thus, the correct answer is option A.
B. the alternate version of a trait
C. the visible trait in the F1 generation
D. a section of DNA that codes for a specific trait
...I think its D but i'm not sure..
A gene is defined as : ( D ) A section of DNA that codes for a specific trait
A gene is a unit of heredity that is found in the DNA of an organism. gene occupies a specific part of the DNA and carries specific trait which is transferred from parents to their offspring across generations.
Genes are made up of nucleotides that are responsible for an organism's possession of certain characteristics or abilities through the coding of certain proteins.
Hence we can conclude that a gene is defined as A section of DNA that codes for a specific trait.

Answer: b. photosynthesis.
Explanation:
Photosynthesis is a chemical reaction that occurs in the cells of the plant leaves. The process requires carbon dioxide from the atmosphere and water as reactants. These reactants get converted into carbohydrates (glucose) and oxygen as byproducts in the presence of sunlight. For the first time on earth the oxygen was produced by the photosynthesizing cyanobacteria. As these organisms used to fix carbon dioxide in water.
Therefore, oxygen was introduced into the atmosphere as a byproduct by the process of photosynthesis.
B.Smog
C.Acid rain
D.Carbon dioxide
d. Carbon Dioxide

B)speciation
C)convergent selection
D)stabilizing selection
Answer:
B)speciation
Explanation:
Speciation is the term used to refer to the division of a lineage that produces two or more different species. In a nutshell, we can say that this is the process of the emergence of a new species, and the crucial event for this to happen is reproductive isolation. This reproductive isolation impedes the gene flow, therefore, obeying the biological concept of species, we say that a new species has emerged.
An example of speciation is shown in the question above, where a volcano separated two species and left them in reproductive isolation. The result of this was that two populations became so different from one another that they became unable to breed, creating new species.
