As invasive species, how does the introduction of the feral pig and the water hyacinth impact an ecosystem? (Site 1)
Answer: invasive species can bring harm to wildlife. a new species means it won't have predator to control the population within the ecosystem. ferral pigs will eat anything including native birds competing with wildlife for food. spreading disease to live stock and humans. spreading e-coli
water hycinth forms dense mats in wild reducing sunlight for submerged plants. crowding out native aquatic plants.
Explanation:

Invasive species can undermine an ecosystem's natural resources and put human usage of those resources in danger.
What are natural resources ?Natural resources are things that come from the Earth and are used to sustain life and satisfy human needs. A natural resource is any natural substance that people use.
Aquaculture species can be released intentionally or accidentally, as well as through aquarium specimens or bait, oceangoing ships' ballast water, aquarium specimens, and other methods.
So, Invasive species can undermine an ecosystem's natural resources and put human usage of those resources in danger.
Invasive species have the ability to wipe out native species, reduce biodiversity, compete with native species for scarce resources, and disrupt habitat.

How will you do define science?Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old.
Moreover, science is a way of knowing about the world. At once a process, a product, and an institution, science enables people to both engage in the construction of new knowledge as well as use information to achieve desired ends.
Hence, science is a broad career field with many specialties and areas of study. The three main branches of science are physical science, earth science and life science, and they each have different career applications.

The reaction releases energy that is available to do work.
The Gibbs free energy is positive.
The reaction cannot spontaneously occur.
The reaction is at equilibirum.
Answer:
The reaction releases energy that is available to do work.
Explanation:
Endergonic reaction releases energy.
The following describes an exergonic reaction - The reaction releases energy that is available to do work.
Exergonic reaction:In chemical thermodynamics, a chemical reaction where the change in the free energy is negative
Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy.Reactions with a positive ∆G (∆G > 0) require an input of energy and are called endergonic reactions.The equilibrium constant for an exergonic reaction is greater than 1, meaning it is not at equilibrium.Thus, The following describes an exergonic reaction - The reaction releases energy that is available to do work.

Answer: The question is incomplete and options are not given, here are the options.
A. Atricial
B. Precocial
C. Hyperbole
D. Hyperactive.
The correct option is precocial.
Explanation:
It is precocial because it is the ability of new hatched birds with full feathers and eye open to be able to move around and find food after been hatched from the egg. It is common in birds and it is gotten from Latin word called precoccous. Some newly hatched birds can be able to mobilise around minutes after hatching and search for food while some cannot move around minutes after hatching to search for food, this type of birds are called Altricial.

-Cellular Respiration -Excretion
Answer:
The correct answer is - cellular respiration.
Explanation:
Cellular respiration is the cellular biochemical process that includes different sets of chemical reaction takes place in mitochondria of the cell from glucose or sugar to the release of a huge amount of chemical energy in the form of ATP with carbon dioxide and water as a byproduct.
ATP or adenosine triphosphate is the basic and primary form of energy used by the cell. Following equation can summarize the complete production of energy from stored nutrients.

You are inserting your gene of interest into the Lac Z gene in a plasmid also containing a tetracycline resistant gene. You plate your transformed bacteria on media containing tetracyline and X-gal (the LacZ substrate that can form a blue dye). What results would indicate a clone with recombinant plasmids?
Answer:
A white colony in tetracyline plates
Explanation:
Beta-galactosidase (also known as beta-gal or β-gal), will not be produced if a gene was cloned into the Lac Z gene. It is because β-galactosidase is produced by the activation of the lacZ gene, and thereby β-gal can not be produced in the absence of this lac operon. In consequence, X-gal will not be hydrolyzed by the β-gal enzyme in a reaction that releases a blue pigment, and thus the colony will be white. In gene cloning, X-gal enables to determine whether a cell is expressing a functional β-gal enzyme, which is known as the "blue/white screening method".
