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.

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.

Answer:A
Explanation:
Why did the temperature change or not change during the reaction?
Answer:
When substances react and the temperature of the mixture decreases, the reaction is endothermic. ... If a reaction is exothermic, more energy is released when the bonds of the products are formed than it takes to break the bonds of the reactants. This is the reason for temperature change during a reaction.

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.

Squirrels eat acorns. Good acorn production happens when there are good growing conditions for the oak trees that make acorns. Often, there are many acorns produced one year but very few acorns the next year. What is the most likely impact on the squirrel population in years when fewer acorns are produced?
Nest size will increase.
Competition will increase.
Predation risks will increase.
Reproduction rates will increase.
Answer:
B competition will increase
Explanation:
this is because if there are less acorns then squirrels then they will all fight for the acorns and some will die to starvation. nest size won't increase because there isn't enough food for the squirrels already there. predation will decrease because there is less squirrels so that means less pray for the animals that eat the squirrels. then there is reproduction rates will increase. It is not that one because there are squirrels dying from starvation there aren't squirrels reproducing. that is why your answer is B.

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.

Which of these costs of using coal is a direct cost?
O A Cost of related pollution
B. Mining costs
O C. Cost of damage to common resources
O D. Human-health costs
Answer:
B. Mining costs
Explanation:
just did ap3x ;)
The costs of using coal is a direct cost that is Mining costs that is in option B as, the cost of related pollution is an indirect cost because it is not a direct expense associated with mining, but rather an expense that arises from the pollution that results from burning coal.
What is direct costs ?Direct costs are expenses that are directly tied to a specific activity or decision. In the case of coal, the direct costs would include the costs associated with mining, transporting, and processing coal. These costs are incurred as a result of the direct activity of extracting and utilizing coal.
Mining costs are a direct cost of using coal because they are expenses incurred directly as a result of the coal mining process. The mining costs would include expenses such as labor costs for miners, equipment costs for excavation and transportation, and other direct costs associated with the mining process.
Hence, The costs of using coal is a direct cost that is Mining costs that is in option B.
