Answer:
While the adult carp prefer slow moving water, they look for high, fast moving water when laying eggs (spawning). They lay hundreds of thousands of eggs at a time, which means populations grow and spread quickly. Because of this, they can quickly out-compete native species, and put ecosystems in danger.Carp are also thought to lower water quality, which can kill off sensitive organisms like native freshwater mussels.Asian carp cause serious damage to the native fish populations in the lakes and rivers that they infest because they out-compete other fish (video, 1 min) for food and space. Carp are also thought to lower water quality, which can kill off sensitive organisms like native freshwater mussels.The Asian carp populations increase rapidly because they are invading native fishes area. They invade native fish like salmon or catfish causing a slight decrease in there population.

Answers
Your final answer: D is the final answer. If you need help, let me know and I will gladly assist you.
In a mutualism both organisms are helped. Therefore, option (D) is correct.
Mutualism benefits both creatures. The trade benefits both organisms. Food, shelter, protection, and other services are examples. The partnership helps both creatures survive, reproduce, and thrive. Nature relies on mutualistic ties for ecological balance and ecosystem function.
Mutualism may be seen in pollination, where plants give nectar to pollinators in exchange for pollen, and in animal digestive systems, where mutualistic microorganisms break down food and offer nutrients. Therefore, option (D) is correct.

In codominance, two alleles can be simultaneously expressed. The correct option is D. 1/2 homozygous brown (BB), 1/2 heterozygous agouti (BW).
What is codominance?Codominance is an inheritable pattern in which two alleles can be simultaneously expressed.
In these situations, heterozygous individuals can express two phenotypes, each of them coded by one allele.
Heterozygous individuals' phenotype is an additive expression of their parents' genes.
In the exposed example, coat color are white, brown and agouti (mixed).

Why do Earth’s crust remain the same size despite sea floor spreading?
A. Older rocks eventually disintegrate on the ocean floor.
B. As new rocks are formed along mid-ocean ridges, older rocks are pushed down deep into the Earth into ocean trenches.
C. Hot magma dissolves all the old rock near the eruption site.
D. None of these choices are correct.
Answers
Answer:
B. As new rocks are formed along mid-ocean ridges, older rocks are pushed down deep into the Earth into ocean trenches.
Why is the Earth not getting larger if the sea floor is slowly spreading?Mainly due to the Atlantic experiencing seabed expansion. The sea bottom is subducting, or moving underground, in the Pacific. This is how the Earth's tectonic plates and geological activities function. The top side of the mantle travels to the bottom at one end and to the top at the other, similar to a conveyor belt. This explains why there are volcanoes, why continents drift, and why our planet's surface is continually changing over the span of millions of years.
Therefore, the planet is not getting bigger because its surface is constantly recycling itself.
New rocks were formed along mid ocean ridges older rocks were pushed down deep into the Earth into ocean trenches.

3.skeletal system
A. only 1
B. only 1 and 2
C. only 1 and 3
D. all -1, 2 and 3
Answers
Answer:
D, all 3.
Explanation:
The nervous system sends a message to the nerves in the dog's bones (which are a part of the skeletal system) to pick up the food. The digestive system breaks down the food.
The organ systems of the dog that is activated when it eats the bread are the digestive, nervous, and skeletal system. Thus, the correct option is D, i.e. all of the above.
What is an Organ System?An organ system may be defined as a cluster of organs that work together to perform specific bodily functions significantly.
When a dog eats bread, the digestive system converts this piece of bread into simpler substances that are absorbed by the small intestine. This is the direct function of the organ system.
Apart from the digestive system, the nervous system sends the message through the impulse to the bones which are part of the skeletal system to grab the nutrients as well as energy for them.
Therefore, the correct for this question is D.

In what way could you increase the rate of the reaction as it taking place in image C?
add more enzyme
add more substrate
remove substrate
remove enzymes
remove product
Answers
Answer:
Add more enzymes
Explanation:
the purpose of enzymes in nature is to increase the rate of chemical reactions inside an organism
Enzymes increases the rate of a reaction. In the given image, the enzyme molecules are not sufficient to combine with that much substrates thus more enzymes have to be added. Hence option A is correct.
What are enzymes?Enzymes are bio-catalysts which catalyses almost all biological reactions in living organisms. Catalysts are substances which increases the rate of a chemical or biochemical reaction without direct involvement and change by itself.
Catalysts helps to attain equilibrium in a reaction faster by decreasing the activation energy of the reactants. Activation energy is the minimum amount of energy required to overcome the potential barrier in a reaction.
An enzyme have a pocket like cavity into which a substrate places properly. The substrate binds with the cavity and forms an enzyme-substrate complex. This complex then forms a transition compound or an intermediate product which then forms a enzyme-product complex.
Enzyme then release the product. Thus enzymes provide a smooth surface for the reactions to take place. Hence by increasing enzyme amount appropriate to the substrate amount the reaction rate increases.
