Explanation:
When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.

which of the following is not part of the cytoskeleton?
Centrioles are not part of the cytoskeleton. Therefore, option D is correct.
What is the cytoskeleton?The cytoskeleton acts as a scaffold to define the form of the cell and the overall arrangement of the cytoplasm, giving the cell a structural framework. The cytoskeleton not only performs this structural function, but it also controls how cells move.
Actin filaments (also known as microfilaments), microtubules, and intermediate filaments are three primary structural elements of a cytoskeleton. A cytoskeleton is present in every eukaryotic cell, including those found in plants, mammals, fungi, and protists. Even prokaryotes have cytoskeletal proteins, but they differ from eukaryotic cells in terms of their constituent parts.
Centrioles are not part of the cytoskeleton. Therefore, option D is correct.

Complete question:
Knowledge of the amino acid sequences is important for several reasons. What is NOT one of those reasons
Amino acid sequences determine the three-dimensional structures of proteins. Knowledge of the sequence of a protein can help to prevent mutations. The sequence of a protein reveals much about its evolutionary history. The sequence of a protein is necessary to determine its function.Answer:
Knowledge of the sequence of a protein can help to prevent mutations.
Explanation:
Amino acids connect to each other by peptidic bonds to form a linear polymer. The number of amino acids composing the chain and the order in which they are arranged determines the primary structure of the protein.
The secondary structure is the folding that the polypeptide chain adopts thanks to the formation of hydrogen bonds between the atoms that form the peptide bond.
Protein functions depend on their aminoacids sequences. The primary structure of the proteins determines the three-dimensional one. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.
By knowing the sequence of amino acids, we can predict the function of the protein and we can classify them into different families. Integrants of these groups have at least 25% of their sequences identical to each other.
Also, the knowledge of the sequence allows establishing evolutionary and genetic relationships between different species.
When a mutation occurs in the sequence -an alteration in the primary structure- the protein function is modified. BUT knowing the sequence of a protein CAN NOT help to prevent mutations.

How is it possible a lead of an extinct fern is found in Antarctica?
Answer:
due to the continental drift
Explanation:
The theory of continental drift states that Earth's continents moved over time (i.e., they have drifted across the Earth's surface over time). The theory of continental drift was proposed by Wegener in the early 20th century. This theory has been incorporated into the idea of plate tectonics, a theory that describes the movement of seven large plates on Earth's lithosphere three billion years ago. The discovery of an extinct Permian order of seed ferns (i.e., Glossopteridales) in the Antarctic continent is nowadays considered as a proof that continents were once joined and moved over time.

Explanation: there
Water pollution caused by rubbish is one of the current issues affecting the majority of the world's water resources.
What is pollution?Pollution is defined as the spread of toxins into the environment that have a negative impact. Pollution can be any kind of material or energy. The majority of these pollutants are released by human activities including burning fossil fuels, driving, and industrial and agricultural emissions. High amounts of air pollution can have a number of negative health effects.
Agriculture is the primary global contributor to water pollution. Agriculture-related pollution is the primary cause of contamination in rivers and streams, the second-leading cause in wetlands, and the third-leading cause in lakes in the United States. Water pollution causes eutrophication, or the uncontrolled growth of phytoplankton in lakes, and depletes aquatic habitats. tainting of the food supply.
Thus, water pollution caused by rubbish is one of the current issues affecting the majority of the world's water resources.

Answer:
Genetic Diversity: 3. Within a species, there is variation within the gene pool Species Diversity: 2. In a forest, there are a number of different species of trees that make up that ecosystem Ecological Diversity: 1. Organisms within an ecosystem are interconnected through food webs.Explanation:
Biodiversity is the variety in all the forms of life that develop in an environment. This variety includes all plants, animals, fungus, and microorganisms living in a certain place, their genetic variability, and the ecosystems these species conform.
According to this, there are three levels of diversity:
Genetic diversity: Among species. Refers to genes variability among species that differentiate them and allows them to adapt to different environments. The genetic charge of one species differs from other species´ genetic charge. Species diversity: Refers to the diversity between species. Expresses the species richness or the different species number in an area, region, country, or ecosystem. Ecological diversity: Refers to the different ecosystems where the different species might inhabit and the way they interact with each other.What is the difference in the function of the glycoprotein structures of an HIV
virion and the cilia of an animal cell? *
Answer:
The glycoprotein structures are used for attachment, and the cilia are used to move fluids surrounding the cell.
The primary difference in the function of the glycoprotein structures of HIV and the cilia of an animal cell is that the glycoproteins are involved in the attachment of viral particles to the cellular membrane while cilia involve in the locomotion and sensory functions.
What are Cilia?Cilia may be defined as small, slender, hair-like projections present on the surface of animal cells. Such types of structures are involved in mechanoreception.
Glycoproteins mediate the function of attachment of viral particles to the host's cell membrane. Through this function, glycoproteins play an essential role in the replication cycle of the virus.
Cilia play an important in the locomotion of cells by migrating the body fluids that surround the cells. This process by cilia can significantly result in the cells migrating through the water.

Age structure data include all of the following except
A. The number of members of a population who are between 5 and 11 years old
B. The ratio of males to females in a population
C. The ratio of older people to younger people in a population
D. The amount of population change due to immigration of emigration
Answer:
b.
Explanation:
sana po ay ako ay nakatulong kahit sa paanong paraan
The correct answer is D. The amount of population change due to immigration or emigration.
Age structure data is a demographic concept that refers to the distribution of different age groups within a population. It provides information about the relative sizes of different age groups and is commonly represented in the form of an age pyramid or age distribution graph.
Now, let's go through the options one by one:
A. The number of members of a population who are between 5 and 11 years old: This is a relevant aspect of age structure data. It provides information about the size of the population within a specific age range.
B. The ratio of males to females in a population: This is also an important aspect of age structure data. It helps us understand the gender distribution within a population and can provide insights into issues such as gender imbalances or gender-based policies.
C. The ratio of older people to younger people in a population: This is another significant aspect of age structure data. It helps us assess the proportion of older individuals (typically above a certain age threshold, such as 65 or 80) compared to younger individuals. This information is particularly valuable for understanding issues related to aging populations and the potential impacts on social and economic systems.
D. The amount of population change due to immigration or emigration: This option is incorrect. Age structure data focuses on the distribution of age groups within a population and does not directly measure population change due to immigration or emigration. While immigration and emigration can affect the composition of age groups, they are not included in age structure data.
In conclusion, age structure data includes options A, B, and C, but it does not include option D.
