Answer:
It is how organisms link or depend on the environment. It is their interactions with the environment.
Explanation:
Answer:
The correct answer is A. The statement is true.
Explanation:
Muscle obtains ATP from glycolysis. When exercise conditions are anaerobic, glucose is degraded to lactate. Lactate is exported into the circulation and is taken up by the liver. The liver synthesizes glucose again from lactate via the gluconeogenic pathway. These two metabolic pathways that allow the coupling of the function of two tissues is what is known as the Cori cycle. The energy cost is 4 P bonds / each glucose that travels both glycolytic-gluconeogenic pathways.
Answer:
Darwin gave the concept in evolution of species.
Explanation:
- As we know the tree of life is quite massive and comparing it needs to be understood well in terms of fossils that were once hidden inside the layers of earth rock masses. The tree is phylogenetic representing the unique ancestral history of every creature.
- Analyzing their morphological, behavioral and habitats are mostly evaluated in the tree of life
- One major challenge is to find the roots of life for the evolutionists.
- Finding out the nature of the last common ancestor.
- Some theories suggest that the same ancestor has the same common history of origin may lead to confusion of evolutionist as acing them becomes difficult.
Answer:
1. Fossil record
2. Comparative anatomy
3. Embryology
4. Biogeography
Explanation:
Evolution is descent with modification. The organic evolution theory states that present complex life forms have evolved from the earlier (simpler) forms of life over time. Some of the most important pieces of evidence in support of the theory of organic evolution are:
1. Fossil record: fossils are dead remains of past living organisms preserved in the rocks of the remote past. These fossils demonstrate the existence of past living organisms that are related to present-day organisms.
2. Comparative anatomy refers to the study of similarities in the anatomy of different species, which provides direct evidence for identifying common ancestry between related species.
3. Embryology: the more recent the ancestor is that two species share, the greatest similarities in embryo structures and the more closely related the species are. In this regard, it is important to highlight that often homologous organs/structures (i.e., organs/structures descended from a common ancestor) can be observed only in embryos.
4. Biogeography refers to the spatial distribution of organisms and species. Species distribution reflects the evolutionary process when it is combined with geological change. For example, taxa that had already appeared before the separation of the continents are often distributed worldwide.
Answer:
This question is incomplete as it does not contain the graphical representation of fishes population over time. The image containing this information has been attached in the attachment section.
The correct answer is D. The nitrogen from the fertilizer made the plants grow too quickly, which hurt the fish.
Explanation:
According to the attached image, artificial fertilizer is being used on a an apple orchard for six years. The orchard is located near a stream which runs out into a small bay.
Based on the results of the sampled population of fishes for five years as represented graphically by researchers (see attached image), it is obvious that the population of the fishes in the bay is reducing over the years. They also observed the growth of plantlike organisms in the bay.
The possible cause of this decline in the population of fishes is the increased growth of these plantlike organisms. The plantlike organisms are algae, which uses the nitrogen content of the artificial fertilizer that washes into the bay from the orchard, as a source of nutrient. This excessive nutrient causes the plantlike organisms to bloom or grow too rapidly- a process called EUTROPHICATION.
Eutrophication causes the oxygen content of the bay to reduce gradually as the blooming of the plantlike organisms depletes oxygen in the water body, thereby, harming aerobic aquatic organisms like fishes in the bay.
Hence, in a nutshell, the reduction in the population of fishes in the bay is as a result of the nitrogen from the fertilizer which made the plantlike organisms grow too quickly, leading to oxygen-depletion and subsequently death of the bay fishes.
