For a certain plant, purple flowers (allele: P) are dominant and white flowers (allele: p) are recessive. A heterozygous purple plant is crossed with a true-breeding (purebred) white plant. What are the possible genotypes (allele pairs) of the offspring?
Answers
The possible genotype of all the offspring will be PP, and Pp as per the given situation.
What is genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype.
The term "genotype" broadly refers to an organism's genetic make-up; in other words, it characterizes an organism's whole gene pool.
The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning.
In the Punnett square attached, the genotype of the organism is PP and Pp, which means the generation will be having purple flower.
Thus, the possible genotype will be 50% PP and 50% Pp.

Photosynthetic organisms produce oxygen based on whether light is available for photosynthesis. These organisms also consume oxygen for cellular respiration in both light and dark environments. In three to five sentences, explain how these conditions relate to gross and net
productivity. (4 points)
Answers
Answer:
Gross productivity refers to the amount of carbon fixed.
Explanation:
Gross productivity refers to the amount of carbon fixed during the process of photosynthesis by all producers such as plants and algae etc in the ecosystem. A large part of the energy that is produced in the process of photosynthesis is used by the plants in the metabolic processes of the producers such as respiration. The net productivity indicates that carbon dioxide plants that is used during the photosynthesis process substracted from carbon dioxide the plants releases during the process of respiration.

When summarizing the process of transcription in a cell as a gene is used to build a polypeptide, which of these statements accurately reflects the process of transcription? You may choose all that apply.
Answers
Answer:
This question lacks options, the options are:
A) An mRNA molecule is produced in the nucleus of the cell.
B) The ribosome attaches to the DNA to build a polypeptide
C) The resulting RNA molecule is a complement of the gene on the DNA.
D) The RNA molecules contains three nucleotides in a row whose bases form
a codon.
E) A polypeptide is synthesized based on the sequence of nucleotides on the tRNA molecule.
The answers are A, C and D
Explanation:
Transcription is the first process of gene expression whereby a mRNA is synthesized from a DNA template. Transcription, which occurs in the NUCLEUS, takes place in three stages namely: initiation, elongation and termination.
- Initiation involves the attachment of RNA polymerase to the DNA molecule, inducing the unzipping of the double stranded DNA.
- Elongation involves the synthesis of RNA strand by adding complementary nucleotides based on the ones read on the DNA strand.
- Termination signals the end of the transcription process.
Based on this question and the above explanation of the transcription process, the following pertains to transcription in the nucleus:
- mRNA molecule is produced in the nucleus of the cell.
- The resulting RNA molecule is a complement of the gene on the DNA.
- RNA molecules contains three nucleotides in a row whose bases form a codon.

8.) magnification
9.) 40x
10.) inverted
Explanation:
Objectives of the microscope have magnification (5x, 10x, 12.5x, 15x) which attaches to the body tube. The nosepiece is found between the stage and the eyepiece or ocular lens. Glass slide is the slide where a specimen is placed for the study and covered with a coverslip, bubble should be avoided while placing the coverslip.
Mirrors need to adjust to seeing the field of view by adjusting the light. After computing the magnification there would be a final image of the specimen that would be inverted due to the two lens used here.

Need help answering this Neurons are constantly firing on a regular basis in order to keep your body functioning. In your words, describe how a neuron utilizes a stimulus to create an action potential. (Be detailed)
Answers
Answer:
Action potentials are generated when information are sent down an axon through the neuron.
Explanation:
Neurons are nerve fibres which uses electrically charged chemicals to bring about an electrical change.
Action potentials can be defined as rapid changes in the membrane potential that spread rapidly along the nerve fiber membrane. Each action potential begins with a sudden change from the normal resting negative membrane potential to a positive potential and then ends with an almost equally rapid change back to the negative potential. The are three stages of action potential, these include:
--> Resting stage: This is the resting membrane potential before the action potential begins. The membrane is said to be 'polarized' during this stage.
--> Depolarisation stage: in this stage, the membrane suddenly becomes very permeable to sodium ions, allowing tremendous numbers of positively charged sodium ions to diffuse to the interior of the axon. That is, the normal polarised state, for example -90 millivolts, is immediately neutralised by the inflowing positively charged sodium ions, with the potential rising rapidly in the positive direction. This is called DEPOLARISATION.
--> Repolarisation stage: This occurs within a few seconds after the membrane becomes highly permeable to sodium ions, the sodium channels begin to close and the potassium channels open more than normal. Then, rapid diffusion of potassium ions to the exterior re- establishes the normal negative resting membrane potential. This is called REPOLARISATION of the membrane.

If B is dominant over b and Bb mates with Bb, about 75% of the offspring will show the dominant trait.
Looking at the cross:

BB and Bb will show the dominant trait while only bb will show the recessive trait.
