Answer:
By crossing plants with purple flowers, dominant, with plants with white flowers the offspring will be 100% purple because all the offspring will receive at least one dominant allele.
Explanation:
The crossing of two plants of pure line, one dominant and one recessive, for a trait —the color of the flowers— will produce a hybrid offspring which will express the dominant trait in its phenotype.
Parental generation:
Plant with purple flowers PP Plant with white flowers ppCross: PP X pp
Punnett Square :
Alleles P P
p Pp Pp
p Pp Pp
Offspring: 100% Plants whose phenotype is purple flowers and Pp genotype.
According to this, the descendants will be 100% plants with purple flowers, hybrids, since all the offspring received at least one dominant allele.

Marcus is hanging a porch swing on his front porch. The first thing he has to do is attach two springs to the ceiling. Then, he fastens the
swing to the springs so that they can stretch and support the weight of the swing. Which two types of potential energy do the springs have?
A. elastic
B. gravitational
C. kinetic
D. stretched
The two types of potential energy that the springs have when Marcus hangs the porch swing on his front porch are (A)elastic potential energy and (B)gravitational potential energy.
The elastic potential energy is stored in the springs due to their deformation from their natural state. The gravitational potential energy is stored in the swing due to its height above the ground, which is determined by the position of the springs.
When Marcus attaches the springs to the ceiling, the springs are stretched and deformed from their natural state. As a result, they store elastic potential energy. This energy is proportional to the amount of deformation, which in turn is proportional to the weight of the swing and the distance the springs are stretched.
When Marcus fastens the swing to the springs, the gravitational potential energy of the swing is determined by its height above the ground. The higher the swing is from the ground, the greater its gravitational potential energy. The swing's height is determined by the length of the springs and their position relative to the ceiling
Therefore, the correct answers are A. elastic potential energy and B. gravitational potential energy.

The geologic species scale has units based on changes in rocks and fossils.
True
False
The geological time scale/species scale is divided into different units of time depending on changes in the rocks and fossils. So the statement is true.
What is the geological time scale?
The lengthy period of time that the Earth's geologic history has taken up is known as geologic time. Starting at the beginning of the Archean Eon (4.0 to 2.5 billion years ago), formal geologic time runs to the present.
The Hadean Eon, an informal time period that runs from around 4.6 billion years ago (corresponding to Earth's first creation) to 4.0 billion years ago, is also frequently included in modern geologic time scales. The period of Earth's history that is reflected by and preserved in the planet's rock layers is known as geologic time.
Events throughout Earth's history are "calendared" according to the geologic time scale. It divides all of the time into named units of abstract time known as eons, eras, periods, epochs, and ages, in declining order of duration. Those geologic time units are counted according to stratigraphy, the correlation, and the categorization of rock layers.
Therefore, the geological time scale is used for dividing different units of time according to changes in rocks and fossils. Hence the statement is true.

what is the highlighted number ?
Answer:
I think it is the atomic mass, or the atomic weight.
Explanation:
The number above the symbol is the atomic mass (or atomic weight). This is the total number of protons and neutrons in an atom. The number below the symbol is the atomic number and this reflects the number of protons in the nucleus of each element's atom.
