Gene therapy has been used to treat and cure cystic fibrosis. Cystic fibrosis is caused by a mutation in a single gene.
What are mutations?A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
Moreover, hereditary mutations include cystic fibrosis, hemophilia, and sickle cell disease. Other mutations can happen on their own during a person's life. These are called sporadic, spontaneous, or new mutations. They affect only some cells.
Therefore, mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection. Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.

The first amphibians evolved about 400,000 years ago.
True or False?
Answer:
False
Explanation:
Amphibians evolved about 365 million years ago from a lobe-finned fish ancestor. As the earliest land vertebrates, amphibians were highly successful for more than 100 million years until reptiles took over as the dominant land vertebrates. The earliest well-known amphibian, Ichthyostega, was found in Late Devonian deposits in Greenland, dating back about 363 million years. The earliest amphibian discovered to date is Elginerpeton, found in Late Devonian rocks of Scotland dating to approximately 368 million years ago.

Compare and contrast what happens in mitosis and meiosis.
Mitosis and Meiosis-their differences and similarities
Similarities: both mitosis and meiosis are multistage processes. The stages are interphase, prophase, metaphase, anaphase and telophase. The same general processes occur in each of these stages for mitosis and meiosis. Interphase is cell growth and DNA replication in preparation for cell division
Differences:(please find it attached below)
The similarities between mitosis and meiosis are as follows:
Both types of cell division take place in the nuclei of the cell.Both involve some common stages like prophase, metaphase, anaphase, and telophase. Both forms of cell division initiate from a diploid parental cell. The occurrence of DNA synthesis happens in both sorts of cell divisions.What is Meiosis?Meiosis may be defined as the type of cell division that occurs in the germs cells of an individual. In this type of cell division, one parental cell produces four haploid daughter cells. It is also known as reductional division.
The differences between mitosis and meiosis are as follows:
Mitosis produces two daughter cells of diploid nature from a parental cell. These daughter cells are genetically identical to their parental cells. Meiosis produces four daughter cells of haploid nature from a parental cell. These daughter cells are genetically different from their parental cell.Therefore, it is well described above.

Distinguish between the fossils of ice age mammals found in the La Brea Tar Pits and the organisms that make up the
fossil fuels of the tar.
Answer:
Explanation:
The tar located in the La Brea tar pits is today a fossil fuel that began its formation many hundreds of millions of years ago from the bodies of marine organisms. During the last ice age that ended a few tens of thousands of years ago, some animals got trapped in the tar and left their bones behind. They are not something that created it but only got trapped in preexisting tar.
Answer:
The tar in the La Brea Tar Pits is a fossil fuel that began forming hundreds of million years ago from the bodies of marine organisms. During the last ice age, a few tens of thousands of years ago, mammals like mammoths and sabertooth cats, became trapped in the tar, leaving their bones behind. The mammals became trapped in the tar that already existed, and were not in fact part of what created it.

What part of the cell is selectively permeable and critical for maintaining homeostasis?
Answer:
The cell membrane
Explanation:
One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.

which of the following best describes C-K Theory
Answer:
C-K theory describes and explains the reasoning of a designer as he thinks of and designs a new object – a new product, service, or process. In addition to its explanatory power, this theoretical framework provides powerful generative mechanisms to overcome cognitive obstacles, thus improving our ability to innovate.
Explanation:
C-K design theory or concept-knowledge theory is both a design theory and a theory of reasoning in design. It defines design reasoning as a logic of expansion processes, i.e. a logic that organizes the generation of unknown objects.

The correct and most appropriate answer option for each of the question are:
1. B. Shed.
2. A. Location/Site.
3. C. Storage place for tools and equipment.
4. A. Boxes, pots, and plots for germinating seeds.
5. A. Soil type.
A nursery bed can be defined as a specially prepared temporary plot of land or garden which serves as a home for raising seedlings (young plants) prior to planting them in the main location (area).
Thus, when older trees in the environment or surrounding dies or are cut-off, these younger plants (trees) propagated in the nursery bed are transferred to replace them.
Some of the criteria or requirements for setting up a nursery bed are;
1. Shed: this is one structure essential in propagating young trees.
2. Location/Site: a place close (near) to a source of water should be chosen because water is essential for plant growth and coolness from extreme heat caused by the sun.
3. Storage place for tools and equipment: it is important to have a complete set of tools or their substitute to be able to carry out all nursery activities properly.
4. Boxes, pots, and plots for germinating seeds: there are three places to germinate seeds, young plants, and young trees.
Pots are used for germinating young trees while boxes and plots are used for raising seedlings.5. Soil type: different plants need different types of soil.

In an ECG pattern, the P wave is caused by?
Answer:
Depolarization of atrial muscle fibers
The P wave in an electrocardiogram (ECG) pattern is caused by the depolarization (contraction) of the atria.
What does this represent?It represents the electrical activity that initiates the contraction of the atrial muscles, which is responsible for pumping blood into the ventricles.
The depolarization wave starts at the sinoatrial (SA) node, also known as the natural pacemaker of the heart, and spreads throughout the atria, leading to their contraction.
The P wave is the first deflection seen on an ECG and signifies the initiation of the cardiac electrical cycle. It provides valuable information about the atrial function and can help diagnose certain cardiac conditions.

Answer:
Cumulonimbus Cloud
Explanation:
Cumulonimbus (from Latin cumulus, "heaped" and nimbus, "rainstorm") is a dense, towering vertical cloud,[1] forming from water vapor carried by powerful upward air currents. If observed during a storm, these clouds may be referred to as thunderheads. Cumulonimbus can form alone, in clusters, or along cold front squall lines. These clouds are capable of producing lightning and other dangerous severe weather, such as tornadoes and hailstones. Cumulonimbus progress from overdeveloped cumulus congestus clouds and may further develop as part of a supercell. Cumulonimbus is abbreviated Cb.

What happens when rainwater hits sand?
Answer:
When we mix sand and water, no reaction takes place. The sand simply settles down at the bottom of the water container. This is because sand is heavier than water and hence cannot float in water. The sand can be separated from the water by simple filtration and can be obtained in its original condition after drying.
