the ecosystem is not yet known.
Which term would best define the fish added to the pond?
O invasive species
O introduced species
O native species
O symbiotic species
The term that would best define the fish added to the pond is INTRODUCED species. These species may be harmful to native species.
Introduced species are exotic species which has arrived there by human activity, which may be harmful to native species.
Introduced species may even be harmful to the entire ecosystem because they can break the delicate equilibrium of the ecosystem.
Introduced species may compete with native species for limited resources (e.g., water resources, foods, habitat, etc).

Describe the reproductive process of an angiosperm, from pollen production through the formation of a seed.
Answer:
The angiosperm life cycle consists of a sporophyte phase and a gametophyte phase. The cells of a sporophyte body have a full complement of chromosomes (i.e., the cells are diploid, or 2n); the sporophyte is the typical plant body that one sees when one looks at an angiosperm.
Explanation:
Sheena's B lymphocytes (B cells) produced antibodies to protect her about 3-5 days after she was exposed to a virus. What type of immunity do antibodies provide
There are two types of immunity: These are acquired immunity and innate immunity.
The type of immunity that these antibodies provide is the acquired immunity.
When an individual's immune system responds to a foreign substance or pathogen, or when a person acquires antibodies from another source, this sort of immunity called the acquired immunity develops. It is a type of immunity developed over time in response to invasion of pathogens.Learn more about acquired immunity: https://brainly.com/question/21480961

For a claim about the natural world to be considered scientific, what attributes must it have?
It must be consistent with only a small portion of relevant observations or data.
It must be open to modification if new evidence doesn't completely support it.
It must be based on scientific observations that can be repeated in a controlled setting.
It must be applicable to future events and occurrences.
Answer: The correct answer is that it must be based on scientific observations that can be repeated in a controlled setting. Explanation: This controlled setting, which replicates the real world encounters is known as scientific experiments. Experiments permit for a smaller scale world where the results can be determined with the manipulation of specific elements in the controlled setting. Experiments assist in the understanding of the natural world.

Medium ground finches with small beaks survived multiple droughts.
Answer:
Explanation:
All of the finches evolved from one ancestral species and adapted to their specific niche. of them evolved from one ancestral species, which colonized the islands only a few million years ago.
Darwin's finches, which was residing in the Galapagos archipelago and Cocos island, constitute an iconic model for studies of speciation and adaptive evolution. All of the finches evolved from one ancestral species and adapted to their specific niche.
What are the characteristics of Darwin's finches?The evolutionary history of Darwin's finches is identified by a gene that explains variation in beak shape within and among species.
The major factor influencing the survival of the medium ground finches is weather and the availability of food.
As all of the finches evolved from a single ancestral species and adapted to their specific niche, it is a specific example of competitive advantage exhibited by Darwin’s finches.
Thus, the correct option is C.

A classmate states that both energy and matter can be created during photosynthesis and cellular respiration. Is this true? Explain
Energy and matter are also produced during photosynthesis.Chemical energy in the form of glucose and matter in the form of oxygen gas are produced during photosynthesis.Since these are the results of the reaction, they are regarded as process outputs.
Can both energy and matter be created during photosynthesis?
Some cells employ a process called photosynthesis to convert light energy into food.Because it enables plants to produce the food required for the rest of the ecosystem, photosynthesis is crucial.Producing organisms, or those that grow their own sustenance, are plants.The foundation of the ecosystem is formed by producers, who transform solar energy into chemical energy in the form of food for themselves and other ecosystem inhabitants.Although many ecosystems are dominated by plants, other organisms are also capable of photosynthesis.Some bacteria and algae are capable of photosynthesizing, and these organisms are the producers in their ecosystem. A biological process called photosynthesis consumes both matter and energy.The world's physical components are made of matter.The capacity to perform work is energy.By use of various mechanisms, matter and energy can be switched for one another.On the other hand, neither matter nor energy can be generated nor destroyed.The first law of thermodynamics is that they constantly evolve into new forms.All processes in the universe operate in this manner.Energy can be transformed into a variety of forms.Several instances include:Chemical drivekinetic energythe potential energy of gravityelastic force The substance and energy persist even after an organism dies.Instead, they are changed into other forms.For instance, both matter and energy are components of plants.Fungi and bacteria in the soil aid in the breakdown of a plant's internal substance into its constituent parts when it dies.These can be used by newly sprouting plants by being recycled into the soil.As a result, neither the energy nor the substance is wasted; rather, they are transformed into new forms.To learn more about photosynthesis refer

what do dna evidence and the fossil record indicate are the ancestors of the living cetaceans, the mammalian group that includes whales, dolphins, and porpoises?
DNA evidence and the fossil record indicate are the ancestors of the living cetaceans were land-dwelling mammals. DNA evidence allows to trace the evolutionary origin of taxonomic groups.
DNA evidence refers to the linear order of nucleotides, which can be used to trace the evolutionary origin of a particular taxonomic group.
When the linear order of DNA nucleotides is conserved, it is known as sequence homology.
Fossils are preserved remains of organisms that once lived on the Earth, which can also be used as evidence to trace the evolutionary origin of a given group.

On average, men have a basal metabolic rate (BMR) of 1.0 kilocalorie per kilogram per hour. Lawrence weighs 198 pounds. Calculate how much energy Lawrence expends for basal metabolism per day.
The energy Lawrence expends for basal metabolism per day is 2,160 kilocalories per day.
Basal metabolic rate is defined as the amount of energy that is used when an individual is at rest.
This energy is used for life sustaining functions such as:
breathing,circulation,nutrient processing andcell production.To calculate the Basal Metabolic Rate for Mr Lawrence,
Lawrence weight = 198 pounds
60
(convert pounds to kilogramme)
1 pound = 0.453592kg
198 pounds = x
xkg = 0.453592 × 198
= 89.8 kg
But BMR for average men = 1 kilocalorie per kilogram per hour.
That is, 1 kilocalories = 1 kg per hour
x kilocalories = 89.8 per day
Therefore for a day = 89.8 × 24 ( 24 hours = 1 day)
= 2155.469184
approximately. = 2,160kilocalories per day

What is a lymph node?No lymph nodes exist in the central nervous system. The lymph nodes are more likely to gather in three locations on each side of the body.
The inguinal nodes in the groin, axillary nodes in the armpit, and cervical nodes in the neck are where these sites are found.
The typical lymph node is enclosed by a connective tissue capsule, which divides it into lymph nodules. The lymph nodules, which are dense aggregations of lymphocytes and macrophages, are divided by lymph sinuses.
Therefore, there are several locations throughout the node's perimeter where afferent lymphatics, which carry lymph there from the periphery and enter the node on its convex side, may be found.
