Answer:
Doppler effect is a change in frequency and wavelength of a wave. It is caused by the change in distance between the thing creating the wave (causer) and whatever is measuring seeing or hearing the wave (watcher or observer). Another word for "causer" is "sender".
HOPE THIS HELPED!!!!!!!!!!!!!! XDDDD
Answer:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.
Explanation:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave. - this is true. Prior to cell division, DNA molecules are organized into large structures called chromosomes. Specific regions of a DNA molecule are called genes. These dictate specific proteins which control our traits.
Genes contain thousands of chromosomes that carry specific information about building proteins for a particular trait. - this is false - genes are segments of DNA that control specific traits by dictating the structure and functions of proteins. Chromosomes contain thousands of genes
Chromosomes are small sections of DNA that contain specific information about a trait to build proteins that people inherit. The thousands of different chromosomes passed from the parents allow for humans to look uniquely different.
- this is false - chromosomes are large structures, genes are the relatively small sections of DNA. Humans have 23 pairs of chromosomes, not thousands.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring. - this is true. In diploid organisms, like humans, have two copies of each chromosome. These chromosomes contain slightly different versions of genes, which make us unique.
When an individual muscle fiber receives a threshold stimulus, it contracts as much as possible. ... a threshold stimulus is the minimum amount of energy needed to make a muscle fiber contract.
One strand of DNA contains many proteins.
