The number of native animal species will not be affected at all.
A non-native animal is introduced into a diverse,
mature ecosystem. Assuming that the non-native
animal has no natural enemies, what immediate
affect will the non-native species have on the
ecosystem?
The new non-native animals will develop new natural enemies.
The native species will become more like the new animal. The

Classify the given terms or examples with the appropriate category.
1. Baroreceptors
2. Chemoreceptors
3. Thermoreceptors
4. Proprioceptors
5. Exteroreceptors
6. Interoceptors
a. general stimulus orgin
b. special modality of stimulus
Answer:
a. general stimulus origin: Proprioceptors, Exteroreceptors, Interoceptors
b. special modality of stimulus: Baroreceptors, Chemoreceptors Thermoreceptors
Explanation:
The sensory modality of stimulus refers to the aspect of a stimulus, and the sensation that is felt after a stimulus has had effect. Different sensory modalities include, temperature(thermoreceptors), light, chemicals(chemoreceptors), pressure(baroreceptors), and sound.
Stimulus origin is a classification system of receptors that indicates where a stimulus stems from. Exteroreceptors detect stimuli from the external environment and an example is the receptors found in the nasal cavity. Interoceptors are found in the internal organs and typically affect the smooth muscles of these organs. Proprioceptors are found in muscles, joints and tendons.

What uses bacteria to copy DNA?
O A. Nuclear transfer
O B. Gel electrophoresis
O C. Recombinant DNA technology
O D. Polymerase chain reaction
Answer:
C.
Explanation:
The method that uses bacteria to copy DNA is recombinant DNA Technology. To copy the DNA, the recombinant DNA method uses bacteria such as E. Coli whose plasmids are combined with various gene to produce the substance that is wanted.
Polymerase chain reaction uses bacteria to copy DNA.Therefore, the correct option is D.
What is polymerase chain reaction?Polymerase Chain Reaction is a laboratory technique used to amplify a specific DNA sequence, making many copies of it. The process involves repeated cycles of heating and cooling a reaction mixture containing the DNA template, primers, and a heat-stable DNA polymerase enzyme.
The DNA polymerase enzyme used in PCR is derived from a bacterium called Thermus aquaticus, which can withstand the high temperatures used in the reaction. By copying the DNA sequence multiple times, PCR enables researchers to study and analyze small amounts of DNA, such as those obtained from crime scenes or ancient fossils.Therefore, the correct option is D.

Answer:
Angiosperms, flowering plants, are divided into two groups: monocots and dicots.
Features of monocot and dicot plants. Images from Purves et al., Life: The Science of Biology, 4th Edition, by Sinauer Associates (www.sinauer.com) and WH Freeman (www.whfreeman.com), used with permission.
Monocot seeds have one "seed leaf" termed a cotyledon (in fact monocot is a shortening of monocotyledon). Dicots have two cotyledons. Both groups, however, have the same basic architecture of nodes, internodes, etc.

what part of DNA contains the genetic code
Answer:
Genetic Code. ... stored on one of the two strands of a DNA molecules as a linear, non-overlapping sequence of the nitrogenous bases Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). These are the "alphabet" of letters that are used to write the "code words".
DNA is the genetic material that has codes for genes that makes up the genotype and phenotype of an organism.
The genetic code is stored on the double helix of the DNA molecule.
They are arranged in a linear manner that does not overlap each other.
The code is represented by the alphabets of nitrogenous bases.
The purines adenine (A) and Guanine (G) and pyrimidines cytosine (C) and thymine (T) are found on the strands.

a researcher has 15 pure bred wild mice which were bron and all were females. they were all mated with a male called Bob.All the offspring were brown/ these were then crossed among themselves with the the following results 293 brown and 115 white. determine the color of bob
Answer:
1. Brown.
2. Brown colour is dominant.
3. 2.5 : 1
Explanation:
The colour of Bob is brown because the offspring produced from mating are also brown. The dominant colour in these mice are brown due to presence of this brown colour in all mice. We know that dominant traits always appear in the form and structure of an organisms and we see all mice have brown colour so we can say that the dominant colour is brown. The ratio of brown to white in the 'grandchildren' are 2.5 : 1 means more mice has brown colour as compared to white.
