DNA evidence and the fossil record indicate are the ancestors of the living cetaceans were land-dwelling mammals. DNA evidence allows to trace the evolutionary origin of taxonomic groups.
DNA evidence refers to the linear order of nucleotides, which can be used to trace the evolutionary origin of a particular taxonomic group.
When the linear order of DNA nucleotides is conserved, it is known as sequence homology.
Fossils are preserved remains of organisms that once lived on the Earth, which can also be used as evidence to trace the evolutionary origin of a given group.

can someone explains (summarize) what photoperiodism is? And if it’s the same as photoperiodism
Answer: photoperiodism means the response of an organism to seasonal changes in day length. Photoperiodism isn't the same as Photoperiod because Photoperiodism merely refers to the potential of the plant to incite flowering relative to the changes in the photoperiod. Thus, photoperiod is a light duration or the length of day and night, while photoperiodism is the effect of light duration on the plant’s growth.

D. A SUBSTITUTION IN DNA CODING CAUSES A MUTATION IN A SPERM CELL.
I THINK ITS D. BUT CAN SOMEONE HELP ME !!!!!
Answer:
yeah
Explanation:
it's obviously D . it's a heritable change because the mutation in the sperm cell is gonna cause a mutation in the zygote
A mutation in the sperm cell will most likely result in heritable change ton the attributes of organisms.
Mutations that happen in vegetative cells such as skin, lung, and brain cells cannot be passed on to future generations.
Heritable mutations are those changes to the DNA sequence of sex cells. Changes elicited by such mutations are passed to future generations because they are germline based.
Sperm cells are sex cells. Thus, changes that occur as a result of mutation to sperm cells are most likely heritable.

The eye has cones sensitive to colors associated with Red, green, and blue
according to the trichromatic theory of color vision.
The trichromatic theory of color vision states that the eyes can view only
three colors which are red, green and blue. This is made through the cones
which are light sensitive pigments in the eyes. The combination of their
wavelengths can be used to create other colors in the visible light spectrum.
The stated facts is the reason why Red, green, and blue is the most
appropriate choice in the list of options.

where is earth's magnetic north pole?
Answer:
The north magnetic pole is a point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down)
Explanation:
There is only one location where this occurs, near (but distinct from) the geographic north pole. The geomagnetic north pole, a related point, is the pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field.
The Earth's magnetic pole is situated at west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W.
What is the Earth's magnetic pole?The generation of the Earth's magnetic field occurs deep within the Earth's interior, in a layer which is known as the outer core to be more precise. Here, the convective energy from the slow-moving molten iron is converted to the electrical and magnetic energies.
The north magnetic pole of the Earth moves over time according to the magnetic changes and flux lobe elongation in the Earth's outer core. In the year 2001, it was determined by the Geological Survey of Canada to lie west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W. It was situated at 83°06′N 117°48′W in 2005.
