The main reason why the upper 1/3 of the esophagus is formed by skeletal muscle is that then there can be voluntary control of swallowing.

In the upper 1/3 of the esophagus, we have conscious control over swallowing because it is under the control of somatic nerves. The somatic nervous system is responsible for the voluntary control of skeletal muscles.

The upper esophageal sphincter is a ring of muscle located at the top of the esophagus that opens and closes as food passes from the mouth into the esophagus. The upper 1/3 of the esophagus is under conscious or voluntary control, while the lower 2/3 is under unconscious or involuntary control because it is formed by smooth muscle.

Protoplasm is the viscous material that supports all internal cellular structures of the organism.

 The viscous material that holds all internal cellular structures in place is known as protoplasm. Protoplasm is used by the cell to perform all vital tasks. The protoplasm performs a number of functions, including as transforming food into living tissue, getting rid of waste, delivering nutrients and oxygen, replacing their worn-out parts, and helping to produce new cells. Protoplasm is sometimes referred to as the structural core of the cell since it serves as the main building block for protoplasm development. It contains a variety of components, including as lipids, proteins, carbohydrates, and nucleic acids.

Most of the time, protoplasm is made up of three elements: the cytoplasm, plasma membrane, and atomic nucleus

Among other things, protoplasm helps with carrying food supplies, removing waste, fostering growth and development, and reproduction.

Dominant traits are characters which are always expressed in an offspring wherever they occur.

Recessive traits on the other hand are expressed only if the dominant trait is absent in the offspring.

In the trait for fur length in guinea pig, there are two alleles for it.

Thus, the possible combination of the two alles will be:

A Population Viability Analysis (PVA) is a modeling technique used by conservation biologists to assess the future viability of a population of a species. It involves using mathematical models to simulate the future population growth of a species, taking into account various factors that may affect its survival.

There are several factors used to make a PVA, including demographic factors such as birth and death rates, sex ratios, and age structure of the population, as well as environmental factors such as habitat quality, availability of resources, and exposure to environmental stressors like pollution or climate change. The model also considers the potential impact of human activities, such as hunting, fishing, and habitat destruction.

PVAs are important conservation tools because they help to identify factors that may be threatening the survival of a species, as well as potential management actions that could be taken to improve the population's viability. For example, a PVA may show that a population is at risk of extinction due to habitat loss or overhunting, and may suggest strategies such as habitat restoration or hunting regulations to mitigate those threats.

To find out whether the volume of water a plant receives affects its growth, Raman should change the independent variable, which is the factor that he thinks may cause changes in the plant's growth. In this case, the independent variable would be the volume of water the plant receives.

To measure the effect of changing the volume of water on the plant's growth, Raman could measure the dependent variable, which is the factor that is affected by changes in the independent variable. In this case, the dependent variable could be the height of the plant or the number of leaves it has.

To ensure that the results of his experiment are valid, Raman should keep two variables constant, or control them. These are known as controlled variables. Two variables he should keep the same are the type of plant he is using and the amount of sunlight the plants receive.

Conclusively, if these variables were not controlled, the results of the experiment would not accurately reflect the effect of changing the volume of water on the plant's growth.

Explanation:

If each codon were composed of only one nucleotide, then there would be no codon for any of the 20 amino acids.

Here, correct option is C.

This is because the genetic code is based on a triplet codon system, meaning that each codon is made up of three nucleotides. Each of the four nucleotides (A, C, G, and T), when used in a triplet codon, can create a total of 64 different codons, but only 20 of those codons code for one of the 20 amino acids.

Since only three nucleotides can be used in a codon, and each codon is made up of only one nucleotide, there would be no codon for any of the 20 amino acids. Therefore, if each codon were composed of only one nucleotide, there would be no code for any of the 20 amino acids.

Creeks generally flow from higher to lower elevation, so the cardinal direction they flow depends on the elevation change along their path.

To determine the cardinal direction a creek flows, you first need to identify the elevation changes along the creek. Start by obtaining a topographic map of the area or analyzing elevation data. Observe the contour lines on the map to understand the changes in elevation, with closer lines representing steeper slopes.

Identify the creek's source (where it begins) at a higher elevation and its endpoint (where it meets another body of water) at a lower elevation. The direction from the source to the endpoint is the cardinal direction the creek flows. For example, if a creek flows from northwest to southeast, its cardinal direction would be southeast.

The structure that is highlighted in the given diagram is infraspinous fossa.

The infraspinous fossa is a large concave region located on the posterior (back) surface of the scapula (shoulder blade). It is one of the two major fossae (depressions) found on the scapula, the other being the supraspinous fossa. The infraspinous fossa is positioned below the scapular spine and is bounded by the medial (inner) border and the posterior (back) border of the scapula.

The infraspinous fossa serves as an attachment site for the infraspinatus muscle, one of the muscles that make up the rotator cuff of the shoulder joint. This muscle plays a key role in shoulder movement and stabilization. The size and depth of the infraspinous fossa allow for the proper functioning and range of motion of the infraspinatus muscle.

In summary, the infraspinous fossa is a concave region on the posterior surface of the scapula that provides an attachment site for the infraspinatus muscle and contributes to shoulder movement and stability.

One cycle of DNA replication is followed by two division of cell division during meiosis, which produces haploid germ cells. Maternal and paternal genes are genetically exchanged as a result of DNA crossing over. Meiosis takes place over two rounds. The cell enters interphase meiosis before the first division , during which time DNA replicates. Thereafter, four phases known as PMAT take place (PMAT stands for prophase, metaphase, anaphase and telophase). After the first PMAT round, a second division one starts. Gametes with a single complete haploid pair of chromosomes are created during meiosis.

Gel electrophoresis can be used to separate molecules by:
a) Length
b) Size
c) Charge

In this process, molecules are separated based on their size and charge, as they move through a gel under the influence of an electric field. Larger molecules move slower than smaller ones, and the charge of the molecules influences their movement through the gel in the process of gel electrophoresis.

Gel electrophoresis is a widely used technique in molecular biology and biochemistry for separating macromolecules, such as DNA, RNA, and proteins, based on their size, charge, and shape.
