Which of the Following is an Example of Parasitism?
A.Tree frogs using a tree to hide from predators
B. Fleas living on a dog, making the dog ill
C. Algae living on a sloth, giving it camouflage
D.Two fish protecting each other from preditors
Fleas on a dog represent parasitism because the fleas benefit by obtaining nutrients at the dog's expense, potentially causing illness to the dog. The example of parasitism among the options provided is B.
Parasitism is a type of symbiotic relationship where one organism, the parasite, benefits at the expense of another organism, the host. The flea acts as a parasite by living on the dog and deriving nutrients from it, while the dog suffers harm, often in the form of illness or discomfort. This detrimental effect on the host is a hallmark of parasitism.

Which ecosystems do NOT have
symbiotic relationships?
A. deserts
B. All ecosystems contain symbiotic relationships.
C tropical rainforests
Answer:
The correct option is B. All ecosystems contain symbiotic relationships.
Explanation:
Symbiotic relationship can be described as a relationship between the organisms of two species. It might be harmful for both the species, beneficial for both the species or just beneficial to one of the species. All ecosystems will have some kind of symbiotic relationships. Hence, option B is correct.
Other options like Option A is false because the desert ecosystem does has symbiotic relationships. For example, the Gobi woodpecker lives on a cactus in a desert. In return it eats the insects and other parasites which harm the cactus.
The correct answer is A. deserts.
Symbiotic relationships are interactions between two or more organisms from different species that live in close physical association with each other. These relationships can be beneficial to one or both organisms (mutualism), beneficial to one while having no effect on the other (commensalism), or beneficial to one while being harmful to the other (parasitism).
In ecosystems, symbiotic relationships are widespread and can be found in virtually all environments where life exists. This includes deserts, tropical rainforests, coral reefs, tundras, and even human bodies, where millions of bacteria form symbiotic relationships with their host.
Option B states that all ecosystems contain symbiotic relationships, which is generally true. However, the question asks for an option that does NOT have symbiotic relationships, which means we are looking for an exception to this general rule.
Deserts (option A) are often characterized by harsh conditions, including extreme temperatures, low precipitation, and limited resources. While it is true that deserts can have fewer visible examples of symbiotic relationships due to the sparse distribution of organisms, symbiotic relationships do still exist in desert ecosystems. For example, cacti may have mutualistic relationships with certain species of birds or insects that nest in them or help with pollination.
Tropical rainforests (option C) are known for their high biodiversity and complex web of interactions, including a multitude of symbiotic relationships.
Therefore, the most accurate answer to the question is that all ecosystems, including deserts, contain symbiotic relationships to some extent. However, if we were to identify an ecosystem with fewer symbiotic relationships compared to others, deserts might be considered due to their extreme conditions and lower organism density. It's important to note that the question's premise is somewhat flawed because symbiotic relationships, even if less visible or less diverse, are present in all ecosystems.
Which of the following is NOT TRUE concerning enzymes?

Why did the development of vascular systems help plants move to land
Answer:
During evolution, plants have acquired a vascular system, which has greatly contributed to the success of land plants. The vascular system allows plants to rapidly transport water and nutrients over long distances between roots, growing deeply in soil, and shoots, growing upward toward the sun.
Answer:
It made it possible to move water within the plant structure.
Explanation:
The evolution of plants occurred, mainly, after atmospheric changes due to the release of oxygen by autotrophic organisms. Thus, the first species to colonize the terrestrial environment were bryophytes and mosses, and the main characteristic that facilitated colonization after the formation of multicellular organisms was the formation of epidermal tissue and structures that guaranteed protection against water loss, the movement of water within the plant.
In the Paleozoic period, the first plants with vascular systems emerged, which developed from the first plant groups that colonized the terrestrial environment. The vascular system is composed of xylem and phloem which are the vessels that conduct nutrients and water within the plant.
About 400 million years ago, ancestral plants went through several events of adaptive irradiation, and diversified into the different species that we know today. These adaptive events were fundamental for the colonization of the terrestrial environment, so that diverse environments with adverse conditions were colonized by the plants.
After the appearance of sap-carrying vessels, plants evolved and tall species emerged that constituted the first forests, even at the end of the Devonian period.
Most of the plants survived the extinction events of the Triassic period, however, the environmental and atmospheric changes may have caused more evolutionary events, mainly in relation to the formation of flowers and fruits, which exponentially increased the biodiversity of terrestrial flora from the period Cretaceous.
In addition to the morphological and physiological changes over evolutionary events, another important process in the evolution of plants is reproduction and, indirectly, dependence on water for this process.
In dogs, gum coloration is co-dominant, with black coloration,
black & pink spotted and pink.
You have a lovely spotted gummed Labrador retriever who has
just had 8 pups. Four of the pups have spotted like your dog.
and 4 have pink gums.
What is the likely phenotype of the sneaky neighbor dog? Show
your work.
Answer:
The phenotype of the sneaky neighbor dog will be pink. Let's consider the phenotype of our spotted gummed Labrador to be CPCB and neighbors dog to be CPCP
CP CB
CP CPCP CPCB
CP CPCP CPCB
The results of this cross show that there will be a probability of having pink dogs as well as spotted dogs. Hence, this proves that the neighbors dog had pink gums.
Final answer:
The genotype of the sneaky neighbor dog is likely pp, resulting in a pink gum phenotype, because when this dog mated with a Bp (black and pink spotted gums) Labrador, half of the puppies had pink gums.
Explanation:
The observation that half of the Labrador retriever puppies have spotted gums while the other half have pink gums suggests that gum coloration in dogs displays a pattern of co-dominance. In this case, the phenotype of the puppies informs us about the possible genotype of the parents.
Since the Labrador mother has spotted gums, her genotype for gum color must be one allele for black and one for pink, expressed as Bp. The appearance of some puppies with pink gums indicates they must be pp, receiving a pink allele from both parents. Thus, the father (the sneaky neighbor dog) must have a pp genotype to produce pups with pink gums when mated with a Bp Labrador.
To conclude, the phenotype of the sneaky neighbor dog is likely to be pink gums.
Amniocentesis is a process in which amniotic fluid is taken from the mother's womb to identify any genetic abnormalities in the fetus. How would the discovery of the human genome contribute to this process?
Answer:
The correct option is "the exact location of a particular disease-causing gene can be determined."
Explanation:
The discovery of the human genome will let us know the sequence of normal genes in a human. By comparing to this sequence, one can easily know if there is any abnormality in the fetus. The exact location where a fault has occurred can be recognized if the sequence of the normal human genome is known. Hence, the discovery of the human genome is very beneficial to the process of amniocentesis.

This is the part of a biogeochemical cycle where nutrients are rapidly moving throughout the systole. The elements tend to only be here for a short period of time.
Answer:
Gaseous cycle
Explanation:
Gaseous cycle inclines to travel more frequently than the sedimentary ones. To adjust more steadily to the changes in the biosphere because of the large atmosphere reservoir. The buildup of carbon dioxide are soon dissipated by wind or taken up by the plants. The extraordinary disturbances i.e. global warming are more often than local disturbances which is wild fires and storm driven events. During the rock phase other salt deposits out as rock and sediment in shallow seas eventually to be weathered and can be recycled.
The question pertains to a stage in biogeochemical cycles where nutrients move rapidly; these cycles help maintain ecosystem health by keeping essential elements available.
The part of a biogeochemical cycle being described relates to a phase where nutrients are in a state of rapid movement and transition, typically referred to as the 'active' or 'main' cycle. In this stage, elements move swiftly through the ecosystem, being taken up by organisms, traveling through food webs, and also cycling through the physical environment, such as soil and water.
This rapid cycling ensures that essential elements remain available to support life. An example is the circulation of nitrogen, which can be rapidly integrated into biological systems through the process of nitrogen fixation and become part of the proteins and nucleic acids in living organisms.
These processes are a crucial part of maintaining ecosystem health because they regulate the availability of mineral nutrients. Through biogeochemical cycles, elements like carbon, nitrogen, and phosphorus are recycled and converted into forms that can be used by plants and other organisms. The efficient functioning of these cycles is essential for the productivity and sustainability of both terrestrial and aquatic ecosystems.What must be done to ensure DNA made is a laboratory is radioactive
