Another trait in pea plants that follows a simple inheritance pattern is flower colour. Purple flowers are a dominant trait while white flowers are a recessive trait.
Explain what this difference means in terms of the alleles for flower colour.
Purple flowers are a dominant trait, so a pea plant only needs one allele for purple flowers in order to have the trait. White flowers are a recessive trait, so a pea plant needs two alleles for white flowers in order to have the trait. If a plant has both a dominant allele and a recessive allele then the dominant trait of purple flowers will be expressed.
When a trait has two separate gene-level versions, there are dominant and recessive traits. The trait that emerges initially or is most obviously displayed in the organism is its dominant trait. Recessive traits are those that are present in the organism but are not visible at the gene level.
The allele that results in a purple flower must be dominant (PP) if a purple and a white flower are crossed and the majority of the offspring are purple. As a result, only the offspring who contain both alleles for white will truly be white (pp). An example of this would be a purple flower, which may have an allele for white but would be purple due to presence of a purple allele (Pp). this type of individual will be heterozygous dominant.The characteristics of an offspring can be easily determined using dominant and recessive alleles.learn more about dominant and recessive traits: https://brainly.com/question/3128896

Which of these is the biggest?
A: climer
B: polymer
C: monomer
D: dimer
Will give brainliest to correct answer
Polymer is the biggest of the given options.
Explanation:
The monomer is a simple repeating unit in a polymer.The monomer can combine with other monomers to give the large molecules like dimer, trimer, polymer.The dimer is a molecule in which two combined monomer units are present.A polymer is a long chain composed of several monomer units which are chemically combined together.The order of increasing size from monomer to polymer:monomer < dimer< polymer
So, from this, we can conclude that polymer is the biggest of the given options.

Receptors that monitor tension in muscles, called ______, consist of peripheral endings of nerve fibers that wrap around collagen bundles in the tissue that connects muscle to bone.
The receptors that monitor tension or stretch in muscles are called muscle spindles.
What are muscle spindles?Muscle spindles are receptors that monitor tension or stretch within the body of a skeletal muscle.
They act by mainly detecting changes in the length of the muscle and convey this information to the brain through afferent neurons for processing.

Explanation:
SER - Smooth Endoplasmic reticulum has no ribosomal particles on the surface .It looks smooth.SER helps in manufacturing of lipids and fat molecules . Important for cell function and plays a crucial role in detoxifying many poisons and drugs in liver vertebrates.in internal respiration oxygen carried in ___ moves into cells, and waste carbon dioxide moves out into___
In internal respiration ,oxygen is carried by arteries into the cells and waste carbon dioxide moves out into the veins.
What is Internal respiration?Internal respiration is the process by which oxygen move from the blood to the interstitial fluid and into the cells where by Waste and carbon dioxide are removed from the other direction, from the cells to the blood.
Therefore, In internal respiration ,oxygen is carried by arteries into the cells and waste carbon dioxide moves out into the veins because arteries carries oxygenated blood while veins carries deoxygenated blood.

How do salt ions/water move through a semi-permeable membrane? What is required for their transport?
Answer:
Water passes through the membrane in a diffusion process called osmosis. During active transport, energy is expended to assist material movement across the membrane in a direction against their concentration gradient. Active transport may take place with the help of protein pumps or through the use of vesicles.

When a neuron is at rest, the charge difference between the inside and the outside of the axon is -70 millivolts (mV). This value is the ________ of the neuronal membrane.
The resting membrane potential is the difference in voltage through the neuronal membrane when the cell is at rest. -70 millivolts (mV) value is the _resting potential_ of the neuronal membrane.
What is the resting membrane potential?The resting membrane potential is the difference in voltage through the membrane between the neuron interior and exterior when the cell is at rest. This is when the neuron is not sending electric signals.
When the neuron is at rest, most ion channels are closed except for K+ channels, which let the ions get out of the cell according to its concentration gradient. Na+ channels remain closed.
Hence, when the neuron is at rest, the membrane is much more permeable to potassium ions (K+) than to other ions, such as sodium (Na+) and chlorine (Cl-).
This value is the _resting potential_ of the neuronal membrane.

(Of course, there was no real thought involved, but imagine that you are a cell that encounters an interesting prokaryotic cell and tries to convince it to be ingested and help you out in some way.
Answer:

Explanation:
Wow, that's such a cool prokaryotic cell. It looks so delicious, I wonder if I can eat it.
"Hey, cell, can I eat you?"
"No, you cannot."
"Please? I would love to have your energy-making properties!"
"How would I benefit from this? It seems like you're being parasitic."
"I would help you, by giving you protection and a safe home. You would give me energy. It seems more like an endosymbiotic relationship to me!"
"Fine, you can ingest me."
I'm so glad they let me eat them, they were so yummy. I can even create energy now, and I have a powerhouse inside me! This is so cool, maybe I should eat that other cell with photosynthetic properties.
SORRY IF THIS IS TERRIBLE I REALLY TRIED
Previously, there was a cell. Moving about the primordial soup, it was making its way through the tough environment. It abruptly came across a little prokaryotic cell.
What is a cell?The cell was glad to have someone to share the environment with since, to be completely honest, it was starting to feel a little lonely. The two cells began to interact often and peacefully cohabit.
The first cell began to consider how much simpler it would be to survive if the other, smaller cell moved in with me. After a brief moment of hesitation, the cell fearlessly said, The rest, as they say, is (endosymbiotic) history.
Studies on the mitochondria and chloroplasts are thought to have come from bacteria living in large cells.
Therefore, this supports the theory that eukaryotic cells developed through endosymbiotic relationships between prokaryotes.

Why is the Sky Blue? and Why does Helium Make your Voice go Funny
Answer:
Explanation:
Usually, the sound waves your vocal cords produce travel through air in your voice box. But when they go through the helium that you've inhaled, they travel about three times faster. That's because helium is so much lighter than air. When sound waves speed up but their frequency stays the same, each wave stretches out.
Answer:
the sky is blue because of the atmosphere and helium does that because it changes the air in our vocal tract and consequently, the speed of sound waves of our voice increases resulting in a squeaky and funny tone.
