The change from a high to a low pitch is a phenomenon known as the Doppler Effect or the Doppler shift. Sounds come in waves and are known as sound waves.
The Doppler Shift or effect is relevant to the location of the person who is hearing the sound. When a person is moving closer to the source of the sound, the wavelengths become shorter and they become low pitch; but when the person moves away from the source of the sound, the wavelengths become longer and become high-pitched.
They have to adapt this would be like a bird with a long thin beak who used to eat just small seeds would have to change,say ..because the seeds were sparse that year...and had to start eating bigger seeds each year they have to do this the offspring would slowly adapt and change so they don't go extinct.
Knowing that she is already 75 years old, even though we don't know her health conditions, we can conclude that the vitamins might help her to avoid any deficiency related to minerals and vitamins, and it might also help her if she has an alimentary restriction meaning that she can't it a food that contains a needed vitamin or mineral.
Hope it helps,
Happy homework/ exam/ study!

That’s the answer I think
Answer:
Explanation:
iPSC (induced Pluripotent Stem Cell) induces differentiated cardiomyocytes (cardiomyocytes, CM), which are human, good uniformity, high purity, and have unique properties of cardiomyocytes such as contractile function, action potential and ion channels.
<em>Genetic mutation is an important factor that contributes to the pathogenesis and development of Alzheimer’s disease (AD). The genetic factors studied include the dominant mutations of genes encoding amyloid-β precursor protein (APP), presenilin 1 (PSEN1), and presenilin 2 (PSEN2). Additionally, more and more genes have been found to be potentially associated with AD, such as apolipoprotein E (APOE), glycogen synthase kinase 3 beta (GSK3B), dual specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A), and Tau. Although many studies on the treatment of AD have not been successful, gene therapy is still considered as a potential way against AD, and some gene-therapy-based therapeutics have entered the clinical trial stage. Existing strategies for gene therapy against AD include gene inactivation, genetic modification, and immunoregulation, etc. </em>
