Acacias communicate with each other in response to insect attack by producing a gas called ethylene.

When antelopes begin to eat the leaves of an acacia tree, the tree emits a signal of ethylene gas into the air through the pores of its leaves. This signal can travel up to 45 meters warning other nearby trees of the presence of herbivores. Once the signal is received, acacias begin to produce tannin in their leaves in amounts that are lethal to antelopes.

With this information, we can conclude that Acacia trees, when eaten by grazing giraffes, release ethylene gas, which prompts other acacias to flood their leaves with bitter tannins.

Hemophilia is a genetic disorder caused by the recessive allele of a diallelic X-linked gene. Hemophilic men carry the recessive allele in their X chromosome. The man XhY is hemophilic.

Hemophilia is a hemorrhagic affection that occurs because the blood does not coagulate as it should in normal conditions.

Hemophilia is a genetic X-linked disorder caused by the recessive form of a diallelic gene.  

In the case of women, this gene expresses complete dominance, meaning that an heterozygous woman is normal but carrier.

Any man who gets the X chromosome carrying the recessive allele expresses the affection.

Let us represent the dominant allele H with the symbol + and the recessive allele h with the symbol -.

Genotypes     Phenotypes                        

X⁺X⁺                 Normal woman

X⁺X⁻                 Normal and carrier woman    

X⁻X⁻                 Hemophilic woman

X⁺Y                  Normal man

X⁻Y                  Hemophilic man                    

In the exposed exposed example, the individual XhY is a man that expresses hemophilia, since he has the X chromosome carrying the recessive allele.

The phenotype displayed in the individual whose genotype is XhY is hemophilia.

If the surface of a bacteria cell was not very antigenic then it can enter host cells and eventually cause harm.

An antigen is any molecular structure present in a pathogenic organism (e.g., bacteria) that can be detected by the immune system.

Antigens usually bind to antibodies that are able to bind specific antigenic features and thus trigger a concomitant immune response.

In conclusion, if a bacteria cell was not very antigenic then it can cause harm.

The correct option for the image showing carbon dioxide moving is the biosphere to the atmosphere. Therefore, the correct option is C.

Respiration and combustion are the main processes by which carbon dioxide [tex]\rm (CO_2)[/tex] is transferred from the biosphere to the atmosphere. In the biosphere, which is made up of all living things and organic matter on Earth, plants and animals release carbon dioxide as a result of consuming oxygen [tex]\rm (O_2)[/tex].

Additionally, human activities such as the combustion of fossil fuels for energy also contribute significantly to atmospheric emissions of carbon dioxide. This human-caused process is a major contributor to the increase in atmospheric carbon dioxide levels, which is a major contributor to climate change.

The correct answer is (A). Deforestation.

Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests.

Moreover, deforestation is the purposeful clearing of forested land. Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction. Deforestation has greatly altered landscapes around the world.

Hence, the loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for Indigenous people.
