Answer:
10%
Explanation: Guanine is 40 which means cytosine is 40
that means that the other 20 is admine and thymine
So thymine is 10 other 10 is admine
40+40+10+10=100

What proportion of the resulting offspring is expected to be male with barred feathers and a pea comb
Assuming diallelic genes that express complete d0minance, 4/16 = 25% of the progeny is expected to be male with barred feathers and a pea comb.
Available data
Male chickens carry two Z chromosomes.Female chickens carry one Z and one W chromosomes.The gene for barring is in the Z chromosome.The barred trait is d0minant over unbarred trait.Gene for comb is aut0s0mic.The rose comb is d0minant over the pea comb.
Assuming diallelic genes that express complete d0minance, let us say that
Barred → Z⁺Z⁺, and Z⁺Z⁻Unbarried → Z⁻Z⁻Rose comb → RR and RrPea comb → rrCross: unbarred male heter0zyg0us for the rose-comb with a barred female with a single comb.

Which lipoprotein carries cholesterol to the cells in your body, but can get stuck in arteries while traveling in the blood, depositing cholesterol that eventually leads to plaque formation?.
LDL (low-density lipoprotein) carry cholesterol from the liver to the tissues and can contribute to the formation of plaque that builds up in the arteries.
What are lipids?Lipids are soluble in fat and to circulate in the blood, which is an aqueous medium, they form lipoprotein complexes called lipoproteins, these constitute a transport medium and circulating reservoir for lipids.
Characteristics of LDL (low-density lipoprotein)Low-density lipoproteins, composed of 50% triglycerides, are the ones that transport the lipids synthesized in the liver to other parts of the body.LDL, composed mainly of cholesterol, when in excess, also deposits it on the walls of the arteries, contributing to the formation of plaque.Therefore, we can conclude that excess LDL (low-density lipoprotein) poses a health risk because it facilitates the accumulation of fat in the arteries.

which organism created all usable food energy on Earth
Answer:
The Sun
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
Answer:
The producer is the answer

grasshoper______________

2. which organism receives the most and least amount of energy?

nonsense=report
In a typical energy pyramid, the grasshopper would be a primary consumer, the spider would be a secondary consumer, the chicken would be a tertiary consumer, the grass would be a producer, while the mushroom would be a decomposer.
The organism that receives the most energy would be the grass while the one that receives the least amount of energy would be the mushroom.
Energy transfer in the ecosystemA depiction of energy transfer in any ecosystem is known as the energy pyramid.
In any energy pyramid, the producer forms the base and receives the most amount of energy directly from the sun.
Primary consumers (grasshopper) feed directly on the producer while secondary consumers (spider) feed directly on the primary consumer.
Tertiary consumers (chicken) feed directly on the secondary consumer while the decomposer (mushroom) decomposes the tertiary consumer when it dies.
As energy travels from one level to another, only about 10% is passed while the rest is lost as heat to the environment.

What could happen if negative feedback inhibition did not signal the pancreas to stop producing insulin when blood sugar levels drop to normal levels?
Answer:
the pancreas releases the hormone glucagon. This moves/goes to the liver in the blood and causes the break-down of glycogen into glucose. The glucose goes into the blood stream and glucose levels increase back to normal.
Explanation:
the pancreas releases the (chemical produced by the body) glucagon. This moves/goes to the liver in the blood and causes the break-down of glycogen into glucose. The glucose goes into the blood stream and blood sugar levels increase back to normal(usual/ commonly and regular/ healthy).
list one example of a falsifiable scientific hypothesis about oreo cookies.
Answer:
Oreo cookies are healthy for us
Explanation:
Look at the nutrition label
Example of Falsifiable Scientific Hypothesis about Oreo Cookies:
"The presence of a specific ingredient in Oreo cookies contributes to increased shelf life."
The example hypothesis presented is falsifiable because it proposes a specific claim that can be tested and potentially proven false through experimentation and observation. In this case, the hypothesis suggests that the presence of a particular ingredient is linked to an increased shelf life of Oreo cookies.
To test this hypothesis, a series of experiments can be designed. One approach might involve preparing batches of Oreo cookies with and without the specific ingredient, then storing them under controlled conditions that simulate real-world storage conditions. The cookies' freshness, texture, and other relevant factors could be monitored over time. If the cookies with the ingredient do not consistently show a prolonged shelf life compared to those without the ingredient, the hypothesis could be rejected.
Falsifiability is a key criterion of a scientific hypothesis because it ensures that the hypothesis can be empirically tested and either confirmed or disproven. In this case, the hypothesis about the ingredient's impact on shelf life can be subjected to experimental investigation, allowing for objective assessment and potential modification of our understanding based on the outcomes. Science relies on falsifiable hypotheses to advance knowledge through evidence-based testing and analysis.

A brown-eyed man with a blue-eyed mother marries a brown-eyed woman with a blue-eyed father. What is the probability that their first child will be brown-eyed
This is based on my assumption that brown is dominant over blue.
Since both parent have parents who are homo_zygous recessive, this tells us that both parents will be hetero_zygous.
When you cross two hetero_zygous parents, it can produce these genotypic and phenotypic ratios:
Genotypic
BB : Bb : bb
1 : 2 : 1
Phenotypic
brown : blue
3 : 1
Therefore there is a 75% chance that they will produce a brown-eyed offspring.

What is the importance of the perichondrium that surrounds cartilage?.
Answer:
The perichondrium located around the cartilage has many important and vital functions. The cartilage is a dynamic structure which remains in constant rigorous motion and highly prone to wear and tear. The perichondrium contains an outer layer of fibrous elastin which resists excessive outwards expansion of the cartilage. Also, a large number of nascent and dividing cartilagenous cells are located in the inner part of the perichondrium which help in growth, repair and wear and tear along with repair and maintenance of the cartilages.
