Skeletal muscles act on the bones and joints to power movement.
What is Smooth muscle?The smooth muscle is the type of muscle that allows you to move your leg to kick a soccer ball. The smooth muscle is represented in diagram A. Smooth muscles may be defined as those muscles that indicate no cross stripes under microscopic magnification.Such types of muscles usually consist of narrow spindle-shaped cells with a single, centrally positioned nucleus.The smooth muscles play an essential role in motility, therefore before kicking a soccer ball you need a small runup which is provided by these muscles.The antagonist actions if muscles like the tibialis anterior and gastrocnemius below the knee move the knee joint. The skeletal muscles of the thighs quadriceps, the hamstrings, and the adductors move the leg from the hip joint.To learn more about smooth muscles, refer to the link:

Explanation:
Differences among individual members of a species are called_
A. fitness
B. natural selection
C. adaptations
D. variations
?
Answer:
D. variations
Explanation:
Differences among individual members of a species are called variations. Variations can refer to differences in physical characteristics, behaviors, or other traits that are present within a species. These variations can be inherited from parents or can arise through mutations or other changes in the genetic material of an individual.
Variations can be important for the process of natural selection, which is the process by which certain traits become more or less common in a population over time based on their impact on an individual's ability to survive and reproduce (fitness). Adaptations are traits that have evolved over time through natural selection and help an individual to better survive and reproduce in a particular environment.
Answer:
D. Variations.
Explanation:
Variation is defined as having any modification caused by environmental factors.
This is exemplified particularly in the Charles Darwin and the finches that he found at Galapagos Island, which essentially had 4 groups of finches with varying size beaks, from the smallest to largest:
1) Green Warbler Finch
2) Small Tree Finch
3) Medium Ground Finch
4) Large Ground Finch.
~
What is found is that, depending on the types of available food, a species may adapt towards eating that particular food source in an effort to keep oneself alive. Any useful traits, therefore, would be passed down through generations, while those who failed to adapt would die out.
However, it is important to note that while variation can be seen, and holds some truth to it, Darwinism theory as a whole is not scientific, as the layering of fossil records does not coincide with the theory itself. Evolution, if it was to have occurred, should evolve in such a way that organisms with similar characteristics should be found in order, rather than modifications found in multiple layers. It is also noteworthy that the Darwinist theory calls for only those who are able to adapt to be able to survive, and that unnecessary traits would, sooner or later, be dropped. However, this is not the case, particularly with humans, as humans take part in many leisurely activities that have no benefit towards one's own survival. Darwin's suggestion is that heritable traits that help organisms survive would be the only ones passed down, but humanity as an example shows that such ideas are in fact not true.

Imagine a transmembrane molecule that lies in the plasma membrane and acts as a receptor for an extracellular signaling molecule. When the ligand-binding domain is inserted into the er during synthesis of this transmembrane molecule, will it lie on the lumen side of the er or the cytoplasm side?.
The ER lumen will contain the ligand-binding domain, which will also travel through the Golgi in the same direction.
The fusion protein-containing vesicle will leave the trans Golgi network in the last stage of transport and fuse with the plasma membrane, exposing the vesicle lumen to the outside of the cell.
Additionally, given that glycosylation occurs in the ER and Golgi lumen, any oligosaccharide subunits that may have been added to the protein will be found on its extracellular domain.
The other chemicals will be linked to peripheral proteins in an extracellular environment. Peripheral proteins can bind to other molecules even when they lack a transmembrane domain.

A. polyploidy
B. crossing-over
C. nondisjunction

Answer:
C. nondisjunction
Explanation:
Turner syndrome likely results from the process called nondisjunction. Nondisjunction refers to the failure of chromosomes to separate correctly during meiosis, the process of cell division that occurs during the production of eggs and sperm. If nondisjunction occurs during the production of eggs, it can result in eggs with an abnormal number of chromosomes. If one of these eggs is fertilized by a sperm with a normal complement of chromosomes, the resulting embryo will have an abnormal number of chromosomes.

Which question, if investigated, would best lead to a better understanding of mendel’s law of independent assortment?a. Why did red hair phenotype skip a generation?b. Would other blonde haired individuals also have brown eyes?c. Why did the son inherit red hair form two brown haired parents?d. Which hair color is the dominant phenotype
The correct answer is:
b. Would other blonde haired individuals also have brown eyes?
Mendel's law of independent sorting states that inheritance of one trait is independent of inheritance of other traits. To better understand this law, we ask the following survey questions:
"How do different traits such as hair and eye color segregate and classify independently during gamete (sperm or egg) formation?"
We address the underlying mechanisms of independent sorting, which explain why we skip , or why individuals can inherit certain traits from their parents.
This means that the transmission of one genetic information for one trait, such as hair color, does not interfere with the transmission of genetic information for another trait, such as eye color.
To understand how this works, it helps to know genetics and how traits are passed on from parents to offspring. Our traits are determined by the genes we inherit from our parents. Each gene has different versions called alleles. For example, a gene that determines hair color may have different alleles for brown hair, blond hair, red hair, etc.
During sexual reproduction, gametes (sperm or eggs) produced by an individual contain only one copy of each gene. This is because gametes are formed through a process called meiosis, in which genetic material is separated from the parent cell into separate gametes. When gametes from two individuals come together to form a new individual, the resulting offspring have a combination of genes from both parents.
The way these genes are passed down from generation to generation is governed by the principles of Mendelian inheritance. One of these principles is the Law of Independent Assortment. This means that the transmission of genetic information for one trait, such as hair color, does not interfere with the transmission of genetic information for another trait, such as eye color.
For example, if someone with brown hair and brown eyes mates with someone with blonde hair and blue eyes, their offspring can have any combination of these traits. For example, brown hair and blue eyes, blonde and brown eyes, or blonde and blue eyes. The particular combination of traits an individual inherits is determined by which gametes of each parent come together during fertilization, and this process is random.
