She also give high priority to class for young musici ans |
|
Answer» Evelyn does not hear music, she feels it. She senses the NOTES through different parts of her body. Initially, she was encouraged by percussionist Ron Forbes, who tuned two drums to different notes and asked her to sense the SOUND without using her ears. She realized that she could feel the higher drum from the waist up and the lower drum from the waist down. This exercise helped Evelyn to open up her mind and body to SOUNDS and vibrations.Evelyn explains that when she plays the xylophone, she senses the sound flowing up the stick and into her fingertips. She LEANS against the drums, stands BAREFOOT on a wooden platform so that she can feel the vibrations. She says how her whole body including her hair is sensitive to her music and its resonances. |

Answer» Reduces the risk of dying from coronary heart disease and of developing high blood pressure, colon cancer, and diabetes.Reduces symptoms of anxiety and depression and fosters improvements in mood and feelings of well-being.Helps develop lean muscle, which aids in controlling weight and reducing body fat.Muscular strength declines as we age, but studies report when people exercise, they are stronger and leaner than others in their age group.Physical activity for people with chronic back pain can be therapeutic.Hypertrophy – Increases in muscle size and strength, protecting bones, joints, osteoporosis, and arthritis.Angiogenesis – formation of blood vessels within muscles – promotes blood flow and removes lactic acid.Endurance – improves cardiovascular function and increases metabolism.Improved coordination – ENHANCES neuromuscular pathways, ALLOWING muscles to contract more quickly and efficiently. calories at an accelerated pace as the muscles work to replenish glycogen stores and the body returns to its RESTING state.Having more lean muscle tissue boosts resting metabolic rate which accounts for between 60 and 75 percent of calories burned daily.Afterburn Effect - Even hours after exercising the body burns HOPE THIS ANSWER WILL HELP YOUExplanation:PLZZZ MARK ME AS A BRAINLIST |

Which of the following plant belongs to gymnosperm 1.marchantia2.chara3.cycus4.Iycopodium |
|
Answer» Heya!!!The answer is : 3. Cycas.Explanation:Gymnosperms are the naked seed-bearing plants. A naked seed means that the OVULES are not COMPLETELY enclosed by sporophytic tissue at the time of fertilization. Most of the seed plants have pollen, which contains and transports the sperm to fertilize the egg. As pollen is resistant to desiccation, the sperm can be transported between plants across LARGE distances without drying up. The gymnosperms (naked seed plants) consists of FOUR phyla. These are conifers, cycads, gingkoes, and gnetophytes. Cycads produce pollen, but the sperm still swims down the pollen tube using flagella. As it also has a naked seed, it is classified as a gymnosperm. Hence, option 3 is correct. #Hope it helps :D#Stay SAFE :)#Follow me.... |

Explain how replicatin is an ex at her mic reation |
|
Answer» DNA replication is the biological PROCESS in which two identical copies of DNA are produced from one ORIGINAL DNA molecule.The steps involved in the process of DNA replication are as follows:The first step in DNA replication is to ‘unzip’ the double-helix structure of the DNA molecule.This is carried out by an enzyme called helicase which breaks the HYDROGEN bonds holding the complementary bases of DNA together (A with T, C with G).The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.One of the strands is oriented in the 3’ to 5’ direction (towards the replication fork), this is the leading strand. The other strand is oriented in the 5’ to 3’ direction (away from the replication fork), this is the lagging strand. As a result of their different orientations, the two strands are replicated differently.A short piece of RNA called a primer (produced by an enzyme called primase) comes along and binds to the end of the leading strand. The primer acts as the starting point for DNA synthesis. DNA polymerase binds to the leading strand and then ‘walks’ along it, adding new complementary nucleotide bases (A, C, G and T) to the strand of DNA in the 5’ to 3’ direction. This replication is continuous. Numerous RNA PRIMERS are made by the primase enzyme and bind at various points along the lagging strand.Chunks of DNA, called Okazaki fragments, are then added to the lagging strand also in the 5’ to 3’ direction. This TYPE of replication is called discontinuous as the Okazaki fragments are joined up later.Once all of the bases are matched up (A with T, C with G), an enzyme called exonuclease strips away the primer(s). The new strand is proofread to make sure there are no mistakes in the new DNA sequence. |
