The right response is B) Only cardiac and smooth.

The muscles that are found inside the body are the smooth and cardiac muscles; for instance, the smooth muscles are found in the stomach, uterus, and intestines, among other places. As a result of not being consciously controlled by the person, these muscles move in an involuntary manner. For instance, cardiac muscles contract to pump blood without the person's conscious control. In contrast, the somatic nervous system, not the autonomic nervous system, regulates the voluntary movements of skeletal muscles that are linked to bones rather than organs.

Answer:

C. Mitosis, Gene expression, differentiation

Explanation:

Stem cells are referred to as undifferentiated cells which has the ability to develop into new specialized cells via cellular differentiation. The stem cell initially undergoes MITOTIC division to form new stem cells.

This stem cells then undergo GENE EXPRESSION by turning off some genes and turning on some in order to specialize the cell type. After this, the cell becomes DIFFERENTIATED i.e becomes another type of cell

Place the phases of a stem cell into the correct order.

The correct order would be mitosis, gene expression and then differentiation.

Stem cells can be defined as undifferentiated cells that possesses the ability to develop into many other different cells of the body. Before a stem cell becomes differentiated, the stem cell undergoes growth, mitosis and then information from the gene (DNA) in the cell will be needed to determine the type of cell it will become and be expressed before differentiating and becoming specialized to give rise to a particular type of cell.

Explanation:

The process of evolution that involves a change in the DNA sequence that leads to evolutionary change is called a mutation.

A mutation is a sudden and lasting alteration in the DNA sequence that can influence genetic variation. Changes in the DNA sequence can influence phenotype, which may or may not have an effect on an organism's fitness. Mutations occur spontaneously, either from errors in DNA replication or from exposure to mutagenic agents. Mutations may happen in either coding or non-coding regions of the DNA, and they can be either silent or expressed.

Evolution is a natural process that results in the gradual change of inherited characteristics in populations over generations. It is the process of alteration in the inherited characteristics of species over successive generations. In other words, it is the process of gradual changes that happen to species over time as they adapt to their environments. It can be defined as a change in the gene frequency in a population over time.

Up to 50% of the groundwater we use outside is lost to the elements including wind, evaporation, and runoff brought on by ineffective irrigation techniques, businesses, and infrastructure.

A liquid transforms into a gas during evaporation. It is simple to picture when puddles of rain "vanish" on a hot day and when wet clothing dries in the sun. In these instances, the sea phase is draining into a gas known as water vapor rather than really dissipating. Global evaporation takes place.

Wind panels, or heat from the sun, is what causes the evaporation process to occur. It takes on moisture from garden soil as well as the biggest lakes and oceans. As the water is uncovered to the sun's heat, its level will drop.

Answer:

The answer would be Prokaryotic Cells

Explanation:

  A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles. These Prokaryotic cells are not divided up on the inside by membrane walls, but consist instead of a single open space.

  The majority of prokaryotic DNA is found in a central region of the cell called the nucleoid, and it typically consists of a single large loop called a circular chromosome. So technically these cells lack nucleuses, while still containing genetic material(s).

Terminal buttons are small bulges found at the end of axons. These buttons are responsible for the release of neurotransmitters, which are chemical messengers that allow for communication between neurons.

When an action potential reaches the terminal button, it triggers the release of neurotransmitters into the synaptic gap, where they bind to receptors on the next neuron, allowing for the transmission of the signal. Terminal buttons play a crucial role in the functioning of the nervous system and are involved in various processes, including learning, memory, and emotion. Dysfunction or damage to terminal buttons can result in neurological disorders such as Parkinson's disease, Alzheimer's disease, and depression. Understanding the function and structure of terminal buttons is essential in advancing our knowledge of the brain and developing treatments for neurological disorders.

Answer:

position effect

Explanation:

Position effect refers to the consequences on the expression of a gene/transgene when it is inserted into a new genomic location, thereby explaining how transgene's behavior is affected by its genomic location. The differences in expression of the inserted gene/transgene are generally due to its proximity to regulatory sequences (e.g., enhancers). Species with larger genomes have many genes as well as long intergenic regions where heterochromatin may spread stochastically (randomly) in order to switch on/off the gene expression, thereby resulting in unstable phenotypes.

When a person receives fluids intravenously (through an IV bag, for example), a saline solution is sometime used. Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death.

Explanation:

The answer is B: It swells.

A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

The answer is (e) plasmodesmata.

Junctions that permit the transfer of water, ions, and molecules between adjacent plant cells are plasmodesmata. Plasmodesmata are connections between adjacent plant cells that enable the transfer of water, ions, and other molecules. Plasmodesmata are channels that traverse the cell wall, allowing small molecules and ions to move freely between cells. These channels are lined with plasma membrane and are often found in pairs. Plasmodesmata can be divided into two categories based on their structural features: primary and secondary plasmodesmata.

Primary plasmodesmata are formed during cell division and are found in most cells. They are formed from small invaginations in the newly formed cell plate that connect the cytoplasm of the two new daughter cells.

Secondary plasmodesmata are formed later in life and are only found in specific cell types, such as root hairs and leaf mesophyll cells. These channels are more complex than primary plasmodesmata and are associated with specific structural proteins, such as the callose-rich sleeve and the surrounding desmotubule.

Overall, plasmodesmata are crucial for intercellular communication and the exchange of nutrients and metabolites between adjacent cells. A single plasmodesma may contain multiple membrane-lined channels, making it possible to exchange large numbers of ions and molecules between cells.
