The carrying capacity of a species in an ecosystem is the continuous rotation of resources.  Option B.

As abiotic or biotic factors change so does the carrying capacity. Natural disasters can destroy ecosystem resources. When resources are destroyed, ecosystems can no longer support large populations. This reduces the payload. Increased food production through improved agricultural practices control of many diseases with modern medicine, and the use of energy to render historically uninhabitable areas.

Earth's habitable is an example of something that can expand its carrying capacity. Altering ecosystems can increase the carrying capacity of some species, as other species are overwhelmed and populated while others are dramatically reduced due to hunting. Carrying capacity is the maximum number of individuals in a population that the environment can support.

Answer:

b) continuous rotation of resources

Explanation:

Continuous rotation of resources will cause a change to the carrying capacity of a species in an ecosystem. Therefore, the option (b) is the correct answer.

Answer:

1) Weathering, Erosion, Disposition

2) Physical weathering is the breakdown of large rocks into fragments by physical forces; the chemical composition of the rock is not changed. Chemical weathering is the breakdown of rock by chemical reactions; the chemical composition is changed.

3) The four forces of erosion are water, wind, gravity, and glaciers.

4) Because the velocity of the river slows down a great deal when it reaches the large body of water, the sediment that the river was carrying is deposited along the mouth of the large body of water.

--------------------------------------------------------------------------------------------------------

Abrasion: Abrasion is the breaking down and wearing away of rock material by the mechanical action of another rock. Three agents of physical weathering that cause abrasion are moving water, wind, and gravity. Also, rocks suspended in thence of a glacier can cause abrasion of other rocks on Earth's surface. This would be a prime example of physical weathering, or mechanical weathering.

----------------------------------------------------------------------------------------------------------

Acid Precipitation: Acid rain causes less erosion than normal rainwater does. Rainwater can break down rocks by dissolving minerals in the rocks. Acid rain is rainwater that is more acidic than normal rainwater. Acid rain can also dissolve the minerals in rocks faster than normal rainwater can. This is chemical weathering.

--------------------------------------------------------------------------------------------------------

Animal actions: Animal and plant mobility is a factor in biological weathering. For instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand. A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock. This is an example of physical weathering.

---------------------------------------------------------------------------------------------------------

Ice wedging: Ice wedging ,sometimes known as frost wedging ,can also cause rocks to break apart. Ice wedging causes cracks in rocks to expand as water seeps in and the water freezes and expands opening the crack further. Rocks formed under pressure deep within earth can become exposed at the surface. This is physical weathering

----------------------------------------------------------------------------------------------------------

Oxidation: Oxidation is another kind of chemical weathering. It occurs when oxygen from air dissolves in water and combines with chemicals in the rocks to form oxides. if the rock contains a lot of iron, then oxidation produces a brown material called iron oxide. This looks like rust on the rock.

Weathering is the chemical and mechanical breakdown of exposed rock. The chemical changes alter the minerals and make them softer, and mechanical weathering physically breaks rock into smaller and smaller pieces.

Erosion is the REMOVAL of those chemically and mechanically softer and broken pieces of rock from their original locations, by gravity, water, ice or wind. Erosion is transport (and as a result, fresh unaltered rock is exposed to wind, water and weather, and THAT becomes weathered in turn). The material being transported is ‘sediment’: sand, silt, mud and gravel.

Deposition is when the weathered and eroded (transported) material is dropped and settles down elsewhere, forming a ‘deposit’ of transported rock material.

If this deposit remains undisturbed long enough, and is buried by enough arriving material, it will eventually go through compaction and chemical reactions forming cement between the grains - thus resulting in a brand new, sedimentary rock.

Weathering, erosion, transport, deposition, compaction and cementation are part of the ‘rock cycle’.

Let’s start with basalt that form at mid ocean spreading centers. At mid ocean spreading centers rock material from the earth’s mantle continuously melts due to continuous decreasing in pressure from the oceanic crust spreading at this point. The molten rock quickly cools at the earth’s surface and forms rock known as basalt that makes up the oceanic crust all over the world. The newly produced oceanic crust rock slowly moves towards a boundary with a continental crust where the oceanic crust subducts beneath the continental crust due to the oceanic crust having a higher density than the continental crust. This is where things get a bit more interesting.

The long, bushy tail of the raccoon may be a selective advantage for this species because the bushy tail helps keep the face warm during a snowstorm (Option d). In addition, it may serve as camouflage and also may act to communicate with other members of the population.

An evolutionary selective advantage is a feature in a species that confer an advantage to survive and reproduce in a particular environmental condition, which may be associated such as in this case to the tail in raccoons.

Therefore, with this data, we can see that an evolutionary selective advantage is any phenotypic feature that enhances the survival and or reproductive rate of individuals in a population or species.

Passive transport is the net movement of substances down a concentration gradient that does not require metabolic energy. Active transport is the movement of substances up a concentration gradient that requires energy.

Explanation:

Passive transport is the net movement of substances down a concentration gradient that does not require metabolic energy. Active transport is the movement of substances up a concentration gradient that requires energy.

Both active transport and passive transport occurs in cells. Active transport involves the movement of materials against concentration gradient. This process requires energy.

Passive transport involves the movement of materials in line with concentration gradient. This process does not requires energy. The exchange of sodium and potassium ions across the cell wall involves active transport.

The niche available after extinction can lead to speciation because there would be an imbalance, making resources formerly occupied by extinct fishes vacant, providing the emergence of new species to take the place of the extinct species.

Speciation can be understood as processes that lead to the formation of new species. They occur due to differences in the genome of different populations of the same species that caused reproductive isolation and, consequently, the appearance of two different species.

With this information, we can conclude that Speciation is the process of formation of new species from lineage separation events from preexisting species.

To complete the question: a diploid organism has four pairs of chromosomes what proportion of gametes would be expected to contain some chromosomes from both parental and maternal origin? assume that there is no crossing over

Answer: 7/8

Explanation:

A diploid organism with four pairs of chromosomes...

Assume that the organism receives chromosomes A, B, C and D from the female parent and A', B', C' and D' from the male parent.

Proportion of gametes from patterns origin is the same as that of matters origin, this we have:

(1/2)^4 = 1/16 where 4 reps the number of possibilities, 1/2 rep the chance

Thus, the proportion of gametes expected to contain some chromosomes from both parental and maternal origin would be

(1 - (1/16 + 1/16)) = 14/16 = 7/8

Explanation:

A testable hypothesis is one that can be tested through empirical research, meaning that it is possible to gather evidence to support or refute it.

A hypothesis is a possible explanation that is proposed for a phenomenon that occurs in nature. In the scientific method, hypotheses are tested by collecting and analyzing data to either support or reject them.

A testable hypothesis could be formed from a question by using the following steps:

Identify the phenomenon that you want to study: Start by identifying the phenomenon that you want to study. This could be a relationship between two variables or a question about how something works. Develop a research question: Based on the phenomenon you want to study, develop a research question that can be answered through empirical research. This question should be specific and should be able to be tested using scientific methods. Formulate a hypothesis: Using your research question, formulate a hypothesis that can be tested through empirical research. This hypothesis should be a statement that proposes a possible explanation for the phenomenon you are studying. It should be clear, concise, and testable.

Test the hypothesis: Once you have developed a testable hypothesis, you can design and conduct experiments to gather data that will either support or refute the hypothesis. If the hypothesis is supported by the data, you can consider it to be a valid explanation for the phenomenon you are studying. If the data refute the hypothesis, you may need to revise it or develop a new hypothesis.

The brain and spinal cord are part of the central nervous system.

The electrical charges that act as nervous signals are called action potentials or nerve impulses.

Jellyfish do not have a brain. Instead, their nervous system is called a nerve net.

After nervous systems began to develop in bilaterally symmetric animals, some developed ventral nerve cords, while chordates developed dorsal nerve cords.

Skeletons that allow for movement by using muscles and squeezing liquid to change the body shape are called hydrostatic skeletons.

Exoskeletons do not grow with arthropods, and so occasionally must be shed and regrown from chitin.

Muscles move endo- and exoskeletons by contracting and relaxing.

Fertilization is the joining of two gametes called sperm and egg.

A fish that lays her eggs in a cluster is initiating cluster or mass fertilization.

Amniotic eggs are an adaptation by reptiles to allow for reproduction and embryo development on land.

Describe three different strategies used by three different animals to thermoregulate.

If you see a snake coiled up in a sunny patch of grass, what can you probably conclude about the type of thermoregulator it is. Why?

If you see a snake coiled up in a sunny patch of grass, you can probably conclude that the snake is an ectotherm. Ectotherms rely on external heat sources, such as the sun, to regulate their body temperature. By basking in the sun, the snake absorbs heat, which helps raise its body temperature to a suitable level for proper physiological functioning.

Answer:

1. central

2. action potential

3. nerve net

4. dorsal

5. hydrostatic

6. Exoskeletons

7. contraction/contracting

8. Fertilization

9. external fertilization

10. Eggs

11. Animals with fur thermoregulate by panting. Winged birds will flap against their mouths/heads to dissipate heat. Humans will produce sweat to evaporatively cool. Polar bears have developed blubber. Bears drop body temperatures during hibernation.

12. Seeing a snake using the warmth of the sun leads us to conclude that it is likely a thermo conformer that cannot produce its own body heat.
