Which statements correctly describe mutations in gametes and mutations in somatic cells?
Mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Mutations to gametes are more likely to be beneficial than mutations to somatic cells.
Mutations to somatic cells will be inherited by an organism's offspring.
Mutations to gametes can be passed on to an organism's offspring
O Mutations to gametes do not involve changes in the DNA.
Mutations to somatic cells are transferred to daughter cells.

Answers

Answer:mutations to gametes can be passed on to an organism's offspring and mutations to somatic cells are only present in the type of cell in which the mutation occurred.

Explanation:The mutation in the somatic cells is known as somatic mutations. As they do not take place in the cells, which give rise to gametes, thus, the mutation is not inherited to the next generation by the sexual means.  

On the other hand, the genetic mutations take place in the germline cells, that is, egg and sperm, because of this the mutations possesses the tendency to get passed on from one generation to another.  

Thus, mutations are only passed on to offspring when they take place in germ cell DNA. The other kind of cells, the somatic cells refers to the rest of the cells in the body and mutations, which takes place in these cells do not get inherited further to the offspring.  

Hence, the correct statements are

The abundance of sodium leak channels in skeletal muscle is ______ the abundance of sodium leak channels in a typical neuron.

Answers

The abundance of sodium channels in muscles is as important as the abundance of sodium leak channels in a typical neuron.

Sodium plays an essential role in the body, this includes important functions such as:

Intervening in the process of muscular contraction.Intervening in the process of interneural communication.

This is possible through sodium channels in cells that allow sodium to enter or leave the cell at very specific times and this causes specific reactions in cells.

In neurons: Sodium channels are abundant and essential because due to the action of sodium signals are passed from one neuron to others.In muscles: Sodium channels are abundant and essential, especially in skeletal muscles. The role is sodium is to contract or relax muscles, which makes movement possible.

Based on this, the presence of these channels in both neurons and skeletal muscles is equally important.

what is the cell wall function and factory part or worker?

Answers

Answer:

Major cell parts function just like the structures and people who work together in a factory. Cells have strong cell walls and a cytoskeleton to keep their shape; the walls are made of fiber for protection just like a factory building has sturdy walls for support.

The cell wall serves as a protective and structural layer surrounding plant, fungal, and bacterial cells. It provides rigidity, support, and defense against external pressures and pathogens.

In various species, the cell wall serves as a robust outer layer. Its primary component in plants is cellulose, which helps to preserve cell structure, limit excessive water absorption, and promote growth. Chitin is found in the cell wall of fungi, providing both structural integrity and protection.

Bacteria have a variety of cell wall compositions; peptidoglycan, for example, is an essential part of many bacterial cell walls. Along with other cellular components, this "factory-like" part of the cell performs its functions. It is comparable to a factory's base, supporting the cell's framework, and worker, guarding against threats and preserving the cell's overall operation.

2. What are the two major subdivisions of the nervous system, and what does each division do?

Answers

Answer:

2 Major Subdivisions:

Central Nervous System

Peripheral Nervous System

Explanation:

The central nervous system (CNS) regulates the majority of bodily and mental activities. It is divided into two parts: the brain and the spinal cord. The brain is the core of our ideas, the translator of our surroundings, and the source of control over physical action.

The PNS is the nerve that links the CNS to the rest of the body. The peripheral nervous system's principal job is to link the brain and spinal cord to the rest of the body and the outside world. The peripheral nervous system sends and receives information to and from the central nervous system. This is done by neurons that convey information from sensory receptors in the eyes, ears, skin, nose, and tongue, as well as stretch receptors and nociceptors in muscles, glands, and other internal organs.

help me with this please 50 POINTS!!!!!! Read the poem. The Village Blacksmithby Henry Wadsworth LongfellowUnder a spreading chestnut-tree The village smithy stands;The smith, a mighty man is he, With large and sinewy hands;And the muscles of his brawny arms Are strong as iron bands.His hair is crisp, and black, and long, His face is like the tan;His brow is wet with honest sweat, He earns whateer he can,And looks the whole world in the face, For he owes not any man.Week in, week out, from morn till night, You can hear his bellows blow;You can hear him swing his heavy sledge, With measured beat and slow,Like a sexton ringing the village bell, When the evening sun is low.And children coming home from school Look in at the open door;They love to see the flaming forge, And hear the bellows roar,And catch the burning sparks that fly Like chaff from a threshing-floor.He goes on Sunday to the church, And sits among his boys;He hears the parson pray and preach, He hears his daughters voice,Singing in the village choir, And it makes his heart rejoice.It sounds to him like her mothers voice, Singing in Paradise!He needs must think of her once more, How in the grave she lies;And with his hard, rough hand he wipes A tear out of his eyes.Toiling,rejoicing,sorrowing, Onward through life he goes;Each morning sees some task begin, Each evening sees it close;Something attempted, something done, Has earned a nights repose.Thanks, thanks to thee, my worthy friend, For the lesson thou hast taught!Thus at the flaming forge of life Our fortunes must be wrought;Thus on its sounding anvil shaped Each burning deed and thought.A theme of The Village Blacksmith is people can take charge of their fate.Which lines from the poem best develop this theme?Thanks, thanks to thee, my worthy friend, / For the lesson thou hast taught!Thus at the flaming forge of life / Our fortunes must be wroughtToiling,rejoicing,sorrowing, / Onward through life he goesThus on its sounding anvil shaped / Each burning deed and thought.
