A gene on a chromosome lies close to another gene controlling a different trait. This indicates that the genes are _. The first
umka2103 [35]

My guess:

I do not know the options to the blanks, but I'd say that the answer to the first one is "strongly linked". Think of a chromosome as a phylogenic chart → 2 species that are beside each other are strongly linked, if compared to 2 species 3 spots apart form each other. So, 2 genes that are close to each other are strongly linked.

I do not know the options to the blanks, but I'd say the answer to the second one is epistasis → which is the interaction between two different genes (different means they're not linked alleles).

Hope it helped,

During cellular respiration what is the direct source of the energu used in the cells of consumers?
nexus9112 [7]

Answer:

Consumers use chemical energy from the chemical bonds within organic molecules such as carbohydrates, lipids,  and amino acids.

Explanation:

<u>Heterotrophs are consumers</u>; they ingest or absorb organic matter (lipids, carbohydrates, proteins, etc.)  made by autotrophs or producers for their energy consumption. Autotrophs include plants, bacteria, and other photosynthesizing organisms, while heterotrophs include animals, fungi, protists, and bacteria.

Heterotrophs obtain energy from food through the process of cellular respiration. For instance, during aerobic respiration in mitochondria, they break down sugars in the form of glucose into carbon dioxide and water to obtain energy in the form of ATP or adenosine triphosphate.

aerobic respiration:      C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

                                      glucose+ oxygen →  carbon dioxide+ water+ energy

Which statement is an example of parasitism? A. Psuedoscorpions hide under beetles’ wings for protection and transport. B. Wasps
sladkih [1.3K]

Wasps laying eggs inside hornworms and after the eggs hatch, the wasp larvae feed on the hornworm is the example of parasitism.

Explanation:

There are five types of relationships in an ecosystem. One of the relationships is parasitism. When we define ecosystem, we talk about the kind of interaction that there is between two or more different species.

Parasitism is the type of interaction between two species, in which one species, most likely a parasite, latches itself onto the other species. That other species then becomes a host to the parasite. After latching itself, it becomes dependent on it's host for resources like food and shelter. But, in this type of relationship, the host species is harmed for resources while the parasite species gains strength over time.
