Answer:
Oviparous
Explanation:
The most common reproductive strategy in marine ecosystems is oviparity. 43% of cartilaginous fish are oviparous.
The most basic answer is that the electromagnetic spectrum is the range of all the wavelengths (frequencies) of electromagnetic radiations. It basically describes the range of light in our universe.
Visible light is the only part of the EM spectrum we can see, but there are many kinds of invisible light waves. There are seven kinds of wavelengths in the EM spectrum: radio, microwave, infrared, visible, ultraviolet, x-ray, and gamma. Radio waves have the lowest frequency, and therefore have the largest wavelengths, which means that gamma rays have the highest frequencies and smallest wavelengths in the electromagnetic spectrum.
Inherited genetic factors : hope it helps
Answer:
Karyotype
Explanation:
A karyotype is a picture of all the chromosomes in an individual. These images are analyzed by geneticists to identify structural changes in the chromosomes or to identify differences in number as is the case for Down syndrome.
Karyotyping is used to identify certain genetic diseases associated with chromosomal aberrations. This is associated with the field of cytogenetics.
