[tex]n[/tex] represents the haploid number of an organism. We know that gametes are haploid, therefore there will 32 chromosomes in each gamete. A somatic cell on the other hand is what we know as a body cell, which is a product of mitosis. Mitosis produces diploid cells which is represented by [tex]2n[/tex]. In order to find this value, simply multiply the [tex]n[/tex] value by 2 and you should get 64 chromosomes in each somatic cell.

Although they are both classified as synovial joints, the hip joint is ______ while sacroiliac joints are ______.
The hip joint is a ball and socket synovial joint that regulate flexion, extension, abduction, adduction, circumduction, and rotation movements and sacroiliac joints are diarthrodial joints.
What is synovial joint?It is a union that is established between bones that have different joint surfaces, which inside is a viscous substance, called synovial fluid.
Characteristics of synovial jointsThe hip joint allows movement around multiple axes, therefore it is classified as a ball and socket synovial joint.The sacroiliac joint is the link between the spine and the hip, being a joint considered diarthrodial because it has synovial fluid in its composition and because it is the only one that has cartilage and a joint capsule.Therefore, we can conclude that the synovial joint contains the synovial fluid, which allows adequate sliding and prevents friction between the joint components.

• a population of salmon with different skin colors that attract mates
Answer:
A population of salmon with different skin colors that attract mates.
Explanation:
This is because the salmon have various skin colors to attract mates, so in natural selection, breeding picks out the most successful colors. For example, a gene that possesses a bright blue color on a salmon attracts females more than a gene that possesses a darker blue color. In breeding, natural selection will occur and there will begin to be more male fish with a bright blue color since they are more successful in breeding, than a darker blue color.

What level of protein synthesis is represented by the coiling of the protein chain backbone into an alpha helix?.
Answer:
hello there
Explanation:
Tertiary structure is the three-dimensional structure of a protein. The tertiary structure is obtained when a protein's secondary structure is folded into a globular form. Two main types of secondary structures that proteins can have is an alpha helix and a beta-sheet.
When the secondary structure of a protein folds into a globular shape, the tertiary structure is formed. An alpha-helix and a beta-sheet are the two primary forms of secondary structures that proteins can have.
What is protein synthesis?Protein synthesis is the process of making proteins.
It is carried out within the cell in biological systems. It occurs in the cytoplasm of prokaryotes.
In eukaryotes, it begins in the nucleus with the formation of a transcript (mRNA) of the coding section of the DNA. The transcript exits the nucleus and travels to the ribosomes for translation into a protein molecule with a particular amino acid sequence.
What Are the Four Protein Structure Types?The primary structure: The main structure of a polypeptide chain is defined as the sequence of amino acids. Proteins are classified into 20 different amino acids. The fundamental sequence of amino acids in a protein is the order in which they appear.Secondary structure: The secondary structure of a protein refers to the backbone's regular, recurring folding patterns. The alpha-helix and the beta-sheet are the two most prevalent folding patterns.Tertiary structure: It refers to the whole polypeptide chain folded into a precise 3D form. Enzymes are typically compact spherical tertiary structures.Structure of Quaternary: Many proteins are made up of several polypeptide chains. A protein's quaternary structure outlines how its many subunits are packed together to form an overall structure.Thus, we can conclude that the tertiary structure of protein synthesis is represented by the coiling of the protein chain backbone into an alpha helix.

What pet ownership trend began in the 17th century? Why was this trend so popular and has it continued today?
Answer:
Pet keeping wasn't generally accepted in Europe until the end of the 17th century, and it wasn't common among the middle classes until the late 18th century. Pet keeping in its present form is probably a 19th century Victorian invention. At this time, it was perceived as a link with the natural world, which itself was no longer seen as threatening. It also allowed a visible demonstration of man's domination over nature.
In present-day societies, dogs have a number of functional roles, from ornamental to status symbol, as helpers, and as companions. Dogs can also act as a channel for personal expression because people express their personality in the breed they own. For example, rare breeds are often used as indicators of status. Guide dogs for blind people and hearing dogs for deaf people are examples of pets who are kept as helpers.
But the most common reason for owning pets in Western societies is companionship. In recent years, there's been a growing awareness of the very positive effects this relationship can have on human health and psychological well-being, and a recognition of the therapeutic value of companion animals.

Discuss the stage of development of the tropical cyclone eloise
The Tropical cyclone was the strongest tropical cyclone to impact since Kenneth in 2019.
EloiseLate on 19 January, hit northern Madagascar as a moderate tropical storm, bringing with it heavy rain and moderate flooding. The storm crossed the island of Madagascar and entered the Channel in the early hours of 21 January.
After moving southwest across the Channel for another 2 days, strengthened into a Category 1 equivalent, due to low wind shear and high sea surface temperatures.
Early on January 23, peaked as a Tropical cyclone Category 2 on the Saffir-Simpson scale as the center of the storm began to move off the coast.
With this information, we can conclude that the cyclone caused major damage in Africa.

B and C C. C and D C D. E and F
Homeostasis keeps the organism in a dynamic equilibrium within the homeostatic range. A disruption in dynamic equilibrium is indicated by the temperature change between point C and D. Option C is correct.
What is homeostasis?
Homeostasis is the organism's capacity to keep the body in constant internal equilibrium, even when the external environment is oscillating.
Homeostasis is critical to keep the correct internal functioning of the body.
Different functions -blood pressure, body temperature, respiratory rate, and blood glucose levels, among others- are kept in a restricted range around a reference point, even though external conditions may be changing.
When a sudden change occurs in the internal functioning that disturbs this equilibrium, the organism counters it back by negative or positive feedback.
Graph interpretationIn the exposed graph we can see,
The restricted range of homeostasis at a constant temperature around 37ºC. Six reference points (A-F) withing 12 hours.Dynamic equilibrium is kept in the range of homeostasis around 37ºC, excepting for point D that reaches 38ºC.
The references point A, B, and C suggest that during the first 10 hours, approximately, the body was in equilibrium.
A change in the internal functioning broke the equilibrium, rising temperature to 38ºC, out of the homeostatic range.
The organism took the internal values to their original state, and at points E and F, the organism was in equilibrium again.
A disruption in dynamic equilibrium is indicated by the temperature change between point C and D.
