If you could genetically engineer any species of organism, what would it be? Would it be a unicorn? A dog-cat hybrid? Your own personal pet giant? Choose any species-real or not—that your imagination desires! Write a paragraph describing your species, what it looks like, and where it lives. Think of any inherited traits the species has that might help it survive in its environment. Thinking of these traits now can help you come up with allele combinations in the next step. Now describe your species in the answer space.

a woman has 3 children aged 4,6 and 9 years why are they not genetically identical
Answer:
: Children usually look a little like their father, and a little like their mother, but they will not be identical to either of their parents. This is because they get half of their DNA and inherited features from each parent.

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).

Please help with just part one and punnet square
The earlobe trait is denoted by E and e alleles, whereas the eye trait is denoted by B and b alleles. The Punnet square allows identifying the expected proportions in the progeny.
The Punnett square and inheritanceThe Punnett square is a diagram used to represent the gamete combinations in order to estimate genotypes and phenotypes in the progeny.
The earlobe trait is denoted by E and e alleles, thereby there are two types of gametes in heterozygous individuals.
In this case:
E e
E EE Ee
e Ee ee
Moreover, the eye trait is denoted by B and b alleles, thereby there are two types of gametes in heterozygous individuals.
In this case:
B b

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.
Parentals) Z⁻Z⁻ Rr x Z⁺W rr
Gametes) Z⁻ R, Z⁻ R, Z⁻ r, Z⁻ r

F1) 4/16 individuals are expected to be males with barred feathers and rose combs, Z⁺Z⁻Rr.
4/16 individuals are expected to be males with barred feathers and pea combs, Z⁺Z⁻rr.
4/16 individuals are expected to be females with unbarred feathers and rose combs, WZ⁻Rr.
4/16 individuals are expected to be females with unbarred feathers and pea combs, WZ⁻rr.

The animals they drop off on the side of the road, and leave there, I try to feed some but I can´t even approach some of them. I live in Oklahoma and we are in the middle of a snow storm and I have seen a few stray dogs, it breaks my heart to see how heartless some people are.
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.
1. what is the role of each organism involved in the energy pyramid?
grasshoper______________
spider__________________
chicken_________________
grass___________________
mushroom_______________
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.

If a cell that has 8 chromosomes goes through mitosis, how many chromosomes will each new cell have?.
Answer:
8 chromosomes
Explanation:
The daughter cells will have the exact same amount of chromosomes as the parent cells. Cells that go through mitosis make two exact copies of each other, so they would have the same amount of cells. (I hope this helps and I'm so sorry if it's wrong)

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.
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

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.
