Introduction of non-native species

Explanation:

That would most likely lead to reduced bird populations is O C. Introduction of non-native species.Non-native predators may also prey on native birds and their eggs, leading to population declines.

Non-native species, also known as alien, exotic, or introduced species, are organisms that have been introduced into a geographic area where they did not occur naturally, either intentionally or unintentionally, by humans.

C. Introduction of non-native species is most likely to lead to reduced bird populations.

Non-native species may compete with native species for resources such as food, nesting sites, and breeding territories, and may also introduce new diseases and parasites that the native species may not be able to cope with.

Non-native predators may also prey on native birds and their eggs, leading to population declines.

Explanation:

Cellular respiration is the process by which organic sugars are broken down to produce energy.

Answer:

It was it harmful for the Chthamalus barnacle to add the Balanus barnacle.

Explanation:

The principle of competitive exclusion says that two different species that share the same niche can not live in the same place. If these species have the same requirements, they can not coexist. Two species can not coexist indefinitely on the bases of the same limited resource.  

When two competing species coexist, this is because of niche partitioning or niche differentiation. If there is not any differentiation between them, the dominant species displaces the weak species.  

In the exposed example, Chthalamus can live in the upper intertidal zone, where Balanus can not live because they can not tolerate desiccation. Balanus live in the lower intertidal zone, where Chthalamus can not live because of its vulnerability to predation. But these two species compete for the middle intertidal zone, where they can both live. Balanus excludes Chthalamus because the first species is much bigger and grows faster than the second one. So the middle intertidal zone is only inhabited by Balanus.  

The area occupied by Chthalamus is smaller in the presence of Balanus. In the absence of Balanus, Chthalamus can live in a bigger area, occupying the middle intertidal zone.

Explanation:

i got a 100 on the Quiz "Earthquakes"

The strategy that geologists use to locate the center of an earthquake is they collect data from seismographs. Thus, the correct option is B.

An earthquake may be defined as an activity that involves the unanticipated and brutal shaking of the ground, generally causing huge destruction, as an outcome of movements within the earth's crust or volcanic action.

Geologists utilize an instrument that is known as a seismograph that measures the strength of an earthquake. With the help of this instrument, they find the center of an earthquake on the basis of the highest strength.

Therefore, the strategy that geologists use to locate the center of an earthquake is they collect data from seismographs. Thus, the correct option is B.

Answer: 200 seeds will be yellow.

Explanation: In this crossing, one parent will produce half of its gametes carrying allele Y and the other half carrying allele y. The other parent will have gametes with allele Y. After fecundation, the offspring could phenotype YY or phenotype Yy.

In genetics, Y is related to the dominant allele and y to the recessive one. In this case, having the Y dominant allele determine the color yellow. Therefore, as all of the offspring has the dominant allele Y for yellow, all of the seeds will be yellow, i.e., 200 seeds will be yellow.

Explanation:

Food chain describes the feeding pattern of a group of organisms in an ecosystem. The food chain shows how one organism in one TROPHIC LEVEL feeds on another organism in another. As organisms are being fed on, energy is being transferred.

A food chain always starts with a PRODUCER, which occupies the first and lowest trophic level. It creates the energy transfer as it obtains energy via photosynthetic process. The flow of energy as shown by an energy pyramid is Producer----First level consumer----Second level consumer------Third level consumer.

However, only about 10% of the available energy is transferred and accessible by the next organism. This is because about 90% of the energy has been lost as heat when the organism undergoes metabolic processes. Hence, if 1000 units of energy was present at the producer level, 10/100 × 1000= 100 units will be available to first level consumers.

Also, 10/100 × 100= 10 units of energy will be available to second level consumers and finally 10/100 × 10= 1 unit of energy will be available to talk third level consumer.

Answer:

Biodiversity is the amount of variety of life on Earth.

Explanation:

Biodiversity boosts ecosystem productivity where each species, no matter how small, it has an important role to play.

For example,

a larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all forms of life.

Because it provides a wide variety of ecological services essential to both ecosystem function and human well-being, biodiversity is important to the health of an ecosystem.

The term "biodiversity" describes the range of living things in an ecosystem, such as plants, animals, fungi, and microorganisms, as well as the genetic diversity found within each species.

Here are some justifications for why ecosystem health depends on biodiversity:

1. Nutrient Cycle: The ability of an ecosystem to cycle nutrients depends on biodiversity.

2. Temperature control: By absorbing carbon dioxide and generating oxygen through photosynthesis, biodiversity helps regulate temperature.

3. Soil health: Biodiversity is essential for the preservation of healthy soil.

4. Controlling pests and diseases in ecosystems: Biodiversity can help in managing pests and diseases.

5. Benefits to the Economy: Humans benefit economically from biodiversity in a number of ways, including access to food, medicine, and other natural resources.

Therefore, biodiversity is important for the health of ecosystems, and its loss can have serious detrimental effects on both ecosystem functioning and human well-being.

Explanation:

Answer:

Water is the basis of all living processes. More than half of the human body is made up of water, while human cells are more than 70 percent water. Thus, most land animals need a supply of fresh water to survive. However, when examining the stores of water on earth, 97.5 percent of it is non-potable salt water. Of the remaining water, 99 percent is locked underground as water or as ice. Thus, less than 1 percent of fresh water is easily accessible from lakes and rivers. Many living things, such as plants, animals, and fungi, are dependent on the small amount of fresh surface water supply, a lack of which can have massive effects on ecosystem dynamics. Humans, of course, have developed technologies to increase water availability, such as digging wells to harvest groundwater, storing rainwater, and using desalination to obtain drinkable water from the ocean. Although this pursuit of drinkable water has been ongoing throughout human history, the supply of fresh water is still a major issue in modern times.

Carbon, the second most abundant element in living organisms, is present in all organic molecules. Its role in the structure of macromolecules is of primary importance to living organisms. Carbon compounds contain especially- high forms of energy, which humans use as fuel. Since the 1800s (the beginning of the Industrial Revolution), the number of countries using massive amounts of fossil fuels increased, which raised the levels of carbon dioxide in the atmosphere. This increase in carbon dioxide has been associated with climate change and other disturbances of the earth’s ecosystems. It is a major environmental concern worldwide.

The carbon cycle is most easily studied as two interconnected sub-cycles: one dealing with rapid carbon exchange among living organisms and the other dealing with the long-term cycling of carbon through geologic processes.

Getting nitrogen into the living world is difficult. Plants and phytoplankton are not equipped to incorporate nitrogen from the atmosphere (which exists as tightly-bonded, triple-covalent N2), even though this molecule comprises approximately 78 percent of the atmosphere. Nitrogen enters the living world via free-living and symbiotic bacteria, which incorporate nitrogen into their macromolecules through nitrogen fixation (conversion of N2). Cyanobacteria live in most aquatic ecosystems where sunlight is present; they play a key role in nitrogen fixation. Cyanobacteria are able to use inorganic sources of nitrogen to “fix” nitrogen. Rhizobium bacteria live symbiotically in the root nodules of legumes (such as peas, beans, and peanuts), providing them with the organic nitrogen they need. Free-living bacteria, such as Azotobacter, are also important nitrogen fixers.

Phosphorus is an essential nutrient for living processes. It is a major component of nucleic acid, both DNA and RNA; of phospholipids, the major component of cell membranes; and, as calcium phosphate, makes up the supportive components of our bones. Phosphorus is often the limiting nutrient (necessary for growth) in aquatic ecosystems.

Phosphorus occurs in nature as the phosphate ion (PO43−). In addition to phosphate runoff as a result of human activity, natural surface runoff occurs when it is leached from phosphate-containing rock by weathering, thus sending phosphates into rivers, lakes, and the ocean. This rock has its origins in the ocean. Phosphate-containing ocean sediments form primarily from the bodies of ocean organisms and from their excretions. However, in remote regions, volcanic ash, aerosols, and mineral dust may also be significant phosphate sources. This sediment then is moved to land over geologic time by the uplifting of areas of the earth’s surface.

Answer:

The Control Group

Explanation:

Answer:

Albumin is a protein that attracts water in the compartment where it is found, that is why when circulating within the blood vessels the blood volume is maintained by this protein, so that the liquid or fluid that makes up the blood volume is retained within the capillaries due to hydrostatic forces and because the albumin protein is hydrophilic.

The albumin is decreasing, that is, in deficit or hypoalbulinemia, less water reaches the blood compartment, therefore the blood pressure or pressure will drop, the blood volume will decrease but not due to loss of it as in hemorrhages, but due to diffusion to other compartments. VASCULAR through the processes of OSMOSIS, in simple words, when this protein descends, water filters from the blood vessels to extravascular compartments, this phenomenon clinically manifests itself as EDEMA.

Explanation:

Hypoalbulinemia also occurs in severe nutritional disorders where ovalbumine is not consumed through the egg, since the person's diet is severely lacking, generating massive edema in the abdominal area or abdominal distension.

The effect that the plasma liquid has in spreading to extravascular spaces is called OSMOSIS, which draws water from the external environment by the oncotic pressure generated by other proteins.

The oncotic pressure is the pressure that is generated when the water diffuses from one compartment to another by attraction of a protein, it happens both with albumin and with other proteins of the organism that are characterized by being hydrophilic or attracting water.

Hypoalbulinemia destroys severe cardiac symptoms due to the high demand that an increase in edema and difficulty of venous return entail along with the fall in blood pressure.
