Answer:

The Punnett square is a square diagram that is used to foretell the genotypes of a particular cross or breeding experiment. The diagram is used by biologists to determine the possibility of an offspring having a precise genotype.

Answer:

A Punnett square is a diagram used to determine the statistical likelihood of each possible genotype of the offspring of two parents for a given trait or traits. Reginald Punnett was applying the laws of probability to work pioneered by Gregor Mendel in the mid-1800s.

Match the terms to their definition. 1. chromosome a cell whose nucleus is not bound by a membrane 2. eukaryote a genetic charac
yanalaym [24]

Answer:

1. chromosome: tight coils of DNA

2. Eukaryote: a cell that has a membrane-bound nucleus

3. Gene: a specific sequence of DNA nucleotides that carry hereditary traits

4. Prokaryote: a cell whose nucleus is not bound by a membrane

5. Trait: genetic characteristic of an individual

Explanation:

Chromosomes are the thread-like structures that appear during cell division. Each chromosome is made up of DNA tightly coiled with its packing proteins.  

A cell is defined as eukaryote or prokaryote on the basis of the presence of a membrane-bound nucleus. The cells that lack the membrane-bound nucleus and other membrane-bound organelles are called prokaryotic cells. Example: bacteria.

The cells that have a membrane bound nucleus in which DNA is present are called eukaryotic cells. Example: Plant cells.

A stretch of DNA that code for a particular protein and thereby regulate specific genetic trait is called a gene. Genes are present on chromosomes and are carried from one generation to next to maintain the genetic traits.

The features of living beings regulated by the gene are called trait. Example: skin color, eye color, etc.

arrange the process of hemostasis in sequence. (separate letters by a comma and space [ex. a, b, c,…])
Nina [5.8K]

The sequence for the process of hemostasis is A, F, B, C, D, E.

<h3>What is Hemostasis?</h3>

Your body's natural response to an injury, hemostasis, stops the bleeding and repairs the damage. This skill typically works to your advantage by preserving blood and avoiding infections. The process can occasionally malfunction, leading to issues with excessive or insufficient clotting. There are four distinct steps to the hemostasis mechanism.

1) Blood vessel constriction.

2) The development of a transient "platelet plug."

3) The coagulation cascade is activated.

4) The last clot, or "fibrin plug," forms.

A series of enzymatic activations that result in the development of a clot containing platelets and fibrin polymer are made easier by hemostasis. While the process of tissue regeneration is taking place, this clot plugs the wounded area, manages the bleeding, and stops further bleeding.
