What are two significant ways your skeletal system and your circulatory system support one another
Answer:The bone marrow within your bones form new red and white blood cells and removes dirty blood cells. After making these new blood cells, it sends them to the circulatory system
Explanation:
Some functions of the skeletal system are more readily observable than others. When you move you can feel how your bones support you, facilitate your movement, and protect the soft organs of your body. Just as the steel beams of a building provide a scaffold to support its weight, the bones and cartilages of your skeletal system compose the scaffold that supports the rest of your body. Without the skeletal system, you would be a limp mass of organs, muscle, and skin. Bones facilitate movement by serving as points of attachment for your muscles. Bones also protect internal organs from injury by covering or surrounding them.

An orchid breeder crosses two types of orchids, one that is tall with a petite bloom and one that is short with a large bloom, with the goal of obtaining a tall orchid with a large bloom. The first cross yields all short flowers with petite blooms. What is the expected yield of tall orchids with large blooms if bred from the first generation
6.25% is the expected yield of tall orchids with large blooms if bred from the first generation.
The genetic explanation of the cross:If orchid plants with two pairs of contrasting characteristics like tall/petite and short/large seeds are crossed the F1 progeny would have all tall plants with petite bloom according to the large bloom of dominance. This implies that tallness is dominant over shortness and the petite bloom is dominant over large bloom. In F2 progeny, there would be some tall plants with petite blooms and short plants with large blooms. However, there would be some plants with recombination of characters such as tall plants with large blooms and short plants with petite blooms. This depicts that tall-short and petite/large traits are inherited independently of each other following law of independent assortment. which states that when two traits are taken in a cross the segregation of one trait is independent of the segregation of other characters.
Phenotypic ratio:9/16 Tallshort : 3/16 Tall petite : 3/16 Tall Large : 1/16 Short Petite ( 9:3:3:1).

The main immediate source of ATP (lasting about 10 seconds) as muscle contractions begin comes from: The main immediate source of ATP (lasting about 10 seconds) as muscle contractions begin comes from: fat. creatine phosphate. glucose. glycogen.
The main immediate source of ATP is creatine phosphate.
The answer is option b.
Creatine phosphate gives about the first 15 seconds of ATP at the beginning of muscle contraction.
Anaerobic glycolysis produces small amounts of ATP within the absence of oxygen for a quick duration. Aerobic metabolism makes use of oxygen to provide much greater ATP, permitting a muscle to work for longer intervals.
Few ATP is stored in a resting muscle. As contraction begins, it's far used up in seconds. More ATP is generated from creatine phosphate for about 15 seconds.

If an organism that is homozygous dominant is crossed with a heterozygote for that trait, the offspring will be __________.
Answer: all of the dominant phenotype
The offspring of an AA x Aa cross are either AA or Aa. All will express the dominant phenotype.
If an organism that is purebred dominant is crossed with one that is heterozygous for a trait, half of the offspring will be purebred dominant and the other half will be heterozygous.
What is dominance?If the allele of a gene is completely showing its character in a heterozygous condition, then it is called "completely dominant." Another allele of the gene that can't be expressed is called recessive.
An example is the cross made between purebred tall (TT) and heterozygous tall (Tt). The purebred will form gametes T, and the heterozygous will form gametes T and t.
From the cross, two genotypes, such as TT and Tt, are developed, each having 50%. All the F1 offspring here are tall in phenotype. All tall and short characters are expressed when the two heterozygous Tt and Tt are crossed.
Hence, if an organism that is purebred dominant is crossed with one that is heterozygous for a trait, half of the offspring will be purebred dominant and the other half will be heterozygous.

Cancer takes time to grow because it is the culmination of a series of genetic and genomic changes called Mutations that enable certain cells to divide more frequently than normal.
What Are Mutations?Changes to an organism's DNA sequence are referred to as mutations. Mutations can be the result of viral infection, exposure to mutagens, or mistakes in DNA replication during cell division. Somatic mutations—those that take place in body cells—cannot be passed on to progeny, whereas germline mutations—those that happen in eggs and sperm—can.Mutagens are environmental elements that trigger mutations. Radiation, substances, and infectious diseases are a few examples of mutagens. The nature of mutations may be spontaneous.TP53, a gene that generates a protein that inhibits the development of tumors, is the gene that is most frequently altered in all malignancies. In addition, this gene's germline mutations can result in Li-Fraumeni syndrome, a rare, inherited condition that increases the risk of getting some malignancies.

The value of n, the Hill coefficient, for hemoglobin is about 2 to 3 times as great as the value for myoglobin.
Hill Equation
The two closely related equations that help to explain the binding of macromolecules to ligands are called the Hill equation. It helps to quantify the interaction between various ligand binding sites.
Hill coefficient
It is used to describe the cooperativity of ligand binding. It can be positive and negative depending on the value of the Hill coefficient. If the value of the Hill coefficient is more than one then it exhibits positively cooperative binding and if it is less than one then it exhibits negatively cooperative binding. Then there is the noncooperative binding where the Hill coefficient value is one. As for the hemoglobin and myoglobin, the values are,
Hill coefficient of hemoglobin is 2.7 - 3.Hill coefficient of myoglobin is 1.0.Thus hemoglobin is positively cooperative and myoglobin exhibits noncooperative binding.
