Answer: my best guess: A. Seeds have one or two small leaves.
Explanation: I hope this helps!
As per the given scenario, Seeds always come in the same size is incorrect. The correct option is C.
What is seed germination?The process of a seed germination is described as the culmination of a series of actions that start with hydration and end with the emergence of the embryonic axis (typically the radicle) from the seed coat.
A seed's seed coat allows water and oxygen to enter when it is exposed to the right conditions. The cells of the embryo begin to expand.
The seed coat then splits open, allowing the shoot or plumule that contains the leaves and stem to emerge first, followed by the root or radicle.
Brad erred when creating the table to illustrate the distinction between a seed and a sprout. There is only one size for seeds is untrue.
Thus, the correct option is C.

In a specific species of frog, the allele for green coloration is dominant over the allele for brown skin coloration. The original population contains 28 HH frogs, 52 Hh frogs, and 20 hh frogs.
At the start of the experiment, the researchers remove all hh frogs from the population.
Calculate the frequency of the recessive allele in the remaining population.
Based on the data provided and the Hardy-Weinberg equilibrium equation, the frequency of the recessive allele in the population is 0.53.
How can the allele frequency be determined?The allele frequency can be calculated from the Hardy-Weinberg equilibrium equation.
The Hardy-Weinberg equilibrium equation is given as:
p^2 + 2pq + q^2 = 1 andp + q = 1where:
p = frequency of the dominant allele in the populationq = frequency of the recessive allele in the populationp2 = percentage of hom0zygous dominant individualsq2 = percentage of hom0zygous recessive individuals2pq = percentage of heterozygous individualsTotal population of frogs = 100
percentage of hom0zygous recessive individuals, q^2 = 28/100 = 28%
Frequency of the recessive allele in the population is calculated as:
[tex]q = \sqrt{ {q}^{2} } [/tex]
[tex]q = \sqrt{0.28} [/tex]
q = 0.53
Therefore, frequency of the recessive allele in the population is 0.53.

Describe two integumentary system mechanisms that help regulate body temperature.
Answer:
dilation of vessels and sweating
Explanation:
The vast blood supply of the skin aids in temperature regulation: dilated vessels enable heat to escape, while constricted vessels retain heat. The blood supply of the skin regulates body temperature. The skin aids in the maintenance of homeostasis. Humidity has an effect on thermoregulation because it reduces perspiration evaporation and, as a result, heat loss.

Explanation:
Would the coupling of the processes shown below be found in a eukaryotic cell? explain why or why not. A diagram of transcription and translation in a eukaryotic cell. Four rna polymerases located one after another in short distances transcribe a strand of dna in the direction from left to right. A polyribosome, comprised of several ribosomes, is attached to every rna polymerase. Each ribosome is located on the mrna strand like beads and translates mrna into polypeptides. The 5 prime end of mrna does not contain any ribosomes and is the first to appear during transcription. Drag the terms on the left to the appropriate blanks on the right to complete the sentence.
Polyribosomes are groups of ribosomes linearly arranged, associated with mRNA, and producing several copies of proteins. The coupling of processes shown in the image can not be found in eukaryotic cells.
What is a polyribosome?
A polyribosome is a group of single ribosomes associated with an mRNA molecule and producing simultaneous translation events of the same protein.
Polyribosomes can be found in both prokaryotic and eukaryotic cells. However, translation occurs at different moments and places in these cells.
⇒ In a prokaryotic cell
Polyribosomes can act before transcriptional termination occurs.
While transcription is still happening, ribosomes can produce many polypeptide copies.
This is because
both transcription and translation occur in the cytoplasm simultaneously. transcription and translation directions are 5' to 3'. mRNA does not need to be modified after transcription.⇒ In eukaryotic cells
Polyribosomes are found in the cytoplasm but only when
the transcription process is over,the mRNA molecule is already modified and left the nucleus.Since transcription occurs in the nucleus and translation in the cytoplasm, they can not be simultaneous.
According to this information, the coupling of processes shown in the image can not be found in eukaryotic cells.

What is always produced in the combustion of organic material.
Answer:
“Combustion always produces carbon dioxide and water”
Explanation:
Water and Carbon dioxide are always produced in the combustion of organic material.
What is combustion of organic material?Combustion involves the oxidation of the carbon in an organic molecule. The fuels that are burned on a large scale to provide energy for heat or electricity include the fossil fuels.
The combustion of organic fuels is a chemical reaction that results in the generation of products and heat. The nature of the process is controlled by heat and mass transfer and can result in very different forms of combustion.
Complete combustion needs a plentiful supply of air so that the elements in the fuel react fully with oxygen. Fuels such as natural gas and petrol contain hydrocarbons. These are compounds of hydrogen and carbon only.
