Explanation:

The dog has fleas, but the medicine to counter this does not work. This means that the fleas have built up a resistance against the drug to ensure continued survival and reproductive success of these organisms. These resistant fleas may have existed in population as the population is always large but in small amounts. Thus, treatment with the drug will lead to the dieing out of the sensitive fleas and then leaving the resistant fleas with the favourable alleles to be selected for.

These favourable traits that have evolved against the drugs are then selected for and the organisms reproduce giving rise to more fleas with these favourable characteristics (being resistant to the drugs) such that their continued survival and reproductive is ensured compared to the sensitive fleas that die out.

Answer:

Answer:  It will increase because coyotes are the competition.

Explanation:

An ecological niche can be defined as the functional role which an organism performs in the ecosystem in order to sustain it's life. The functional roles include how an organism obtains it's food, type of food eaten by the organism, type of habitat chosen by the organism and type of breeding season used by the organism.

In the given situation, both coyotes and rattlesnakes are dependent upon the same ecological niche that is they are dependent upon mouse as a primary part of their diets. As, both coyotes and rattlesnakes are dependent upon the same diet there may exist the competition between the two species. But it is mentioned that the coyote population is decreasing therefore the population of rattlesnake will most likely increase as the competition for the same diet decreased.  

Answer:

D

Explanation:

Answer:

Organisms’ characteristics can be used to determine the evolutionary relationships among them. The more closely related two organisms, the more characteristics they have in common. These shared characteristics, along with the fossil record, indicate that organisms have evolved over time from a common ancestor.

Answer:

There are 4 types of breezes: land breeze, sea breeze, mountain breeze and valley breeze.

The breeze will originate from an area of high pressure and travel towards/blow in the direction of the area at a lower pressure.

In each case, the name of the breeze indicates where the breeze is blowing from. For instance, the land breeze will blow from the land (at high pressure) to the sea (at lower pressure). A mountain breeze will blow from mountain (at high pressure) towards the valley (at low pressure).

Answer:

Asexual spores comes with both the male and female reproductive parts, in which one part of the spore produces the sperm (male), which mates with the egg (female), which is produced in a different part of the spore. It is asexual, for the beast or plant only needs itself (not another of the same family) to reproduce.

Characteristics of Fungi. Following are the important characteristics of fungi: Fungi are eukaryotic, non-vascular, non-motile and heterotrophic organisms. They may be unicellular or filamentous. They reproduce by means of spores. Fungi exhibit the phenomenon of alternation of generation.

Answer:

Crabon is consumed by plants to produce food and taken by other organism as food from plants. They release then CO2 either through respiration or when they die. During this entire chain, carbon moves through all the spheres of earth

Explanation:

Carbon constitutes the base of life on earth. Carbon and its compound regulate between the different spheres of earth to sustain the ecosystems and flow of nutrients and energy.  

Carbon is exchanged between all the hemisphere i.e   biosphere, geosphere, hydrosphere and atmosphere. For instance – The ocean consists of largest reserve of carbon on earth (part of hydrosphere), Terrestrial biosphere comprising of non-living organic materials and fresh water sources as sink of carbon in biosphere. The sediments and soils consists of carbon (geosphere) and atmosphere consists of a large amount of gaseous carbon dioxide.  

Plants take in gaseous carbon dioxide and produces food that stores in it or is consumed by other living organisms. When these organic animals or plants die eventually, they release the solid carbon contained within them either in the geosphere, biosphere or hydrosphere.  

Answer:

1. Building into the ecosystem.

2. Hunting animals for sport.

3. Increasing carbon emissions.

Explanation:

All of these are bad for Earth's biodiversity. Building into the ecosystem destroys habitats for animals, which causes the population of that species to decline. Hunting animals for sport decreases populations as well, and doesn't keep the environment in check. Increasing carbon emissions heat up the Earth, leading to colder climates warming up. This, in turn, destroys the ecosystem as well.

Anthropogenic activities and continued neglect of the ecosystem has lead to various deleterious effect on biodiversity.

It means the presence of several species of animals, microorganisms, and plants in a habitat.

According to this theory, the ecosystem is kept together by thousands of species, just as thousands of rivets hold together an airplane.

It may not affect flight safety at first if rivets are removed but over time, the airframe becomes dangerously weak. Similarly, species extinction in the ecosystem impairs the ecosystem's ability to function properly.

Habitat loss and fragmentation:  It destroys the natural habitat and niche of organisms and leads to their decline

overexploitation: It leads to depletion of the natural resources and increases the risk of extinction of endangered species.

Pollution: It destroys the quality of the habitat of organisms and creates a toxic environment which leads to the decline of species.

Answer:

the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved. ... Another form of evidence of evolution is the convergence of form in organisms that share similar environments.

Answer:

Aquaculture means to foster organisms (for the most part fish) that live in water.

Explanation:

After reading Holt Enviromental Science's Food and Agricultural Section:  Animals and Agriculture passage, you can define aquaculture. In the passage it reads "fish farms generally consist of many individual ponds that each contain fish at a specific stage of development." The fish grow until they are matured and then "they are harvested."

Answer: Hemostasis includes three steps that occur in a rapid sequence:

Explanation: 1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels; (2) formation of a platelet plug; and (3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot.

or:

The Blood Clotting Process

Injury. A small tear in a blood vessel wall (for example, from a cut on the skin or an internal injury) causes bleeding.

Vessel constriction. To control blood loss the blood vessel narrows (called constriction), thus limiting blood flow through the vessel.

Platelet plug. ...

Fibrin clot.

Answer:

Your body can't absorb proteins in their natural state. Certain proteases in your stomach and pancreas break the bonds that hold the amino acids in protein together so your body can absorb the composite amino acids individually.

Food molecules cannot be absorbed unless digested because ; They are too big to pass through the plasma membrane, in their natural state.

The food molecules such as protein needs to be broken down into its composites amino acids for easy absorption. food molecules, cannot be absorbed in their natural state because they are too big to pass through the plasma membrane.

Protein is broken down ( digested ) by proteases and pancreas into composite amino acids that is absorbable into the human cells.

Hence we can conclude that protein cannot be absorbed unless digested because they are too big to pass through the plasma membrane, in their natural state.
