A.
sedimentation
B.
melting
C.

D.
mineral integration
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

If a crystal of potassium permanganate is placed on agar and after 15 minutes the diameter of the area over which the dye has spread is 15 mm, the average diffusion rate is
Answer:
Diffusion rate is 1.96 × \(10^{-3}\) \(cm^{2}\)/s
Explanation:
Diffusion is the process in which the molecules of a substance propagates from a region of higher concentration to region of lower concentration through a semi-permeable membrane.
diffusion rate = \(\frac{area}{time}\)
Given that; diameter = 15 mm, time = 15 minutes.
The dye spread in a circular form, so that;
area = \(\pi\)\(r^{2}\)
r = \(\frac{diameter}{2}\) = \(\frac{15}{2}\) = 7.5 mm = 0.75 cm
area = \(\frac{22}{7}\) × \((0.75)^{2}\) = 1.7679 \(cm^{2}\)
time = 15 minutes = 15 × 60 = 900 seconds
So that;
diffusion rate = \(\frac{1.7679}{900}\)
= 0.0019643 \(cm^{2}\)/s
Diffusion rate is 1.96 × \(10^{-3}\) \(cm^{2}\)/s

HELPMEH 20 PTS reeeeeeeeeeA purple (Pp) flower crosses with a white (pp) flower. Use a Punnett square. What is the probability of producing a white flower offspring? Explain.
Answer: 50%
Explanation:
I got 50% because the purple and white is a 50/50 chance. Meaning that the white is 50% and the purple would be a 50%.
The large P is Horizontal and all the small p are on the top. The large P is dominant, while small p is not. If there were 2 big P then all flower crosses would be purple.

Chromosomes are composed of two types of biomolecules. One of the biomolecules in chromosomes is called DNA, which functions as the genetic code. The other biomolecules in chromosomes are called histones, which bind the DNA tightly for cell division. Genes in DNA have the code for making histones. Based on the information above, which types of biomolecules are in chromosomes?
F Carbohydrates and lipids
G Proteins and nucleic acids
H Proteins and carbohydrates
J Nucleic acids and carbohydrates cationTM Inc
Answer:
proteins and nucleic acids
histones are proteins and DNA is made up of nucleic acids (these are the macromolecules made up of nucleotides)
Explanation:
Chromosomes are thread like structure found in nucleus of cells. It contains several biomolecules in it. DNA is nucleic acid whereas histones are protein. Hence, option “ G” is correct.
What are biomolecules?Molecules that are produced by living organisms are called biomolecules.
Example of biomolecules are Carbohydrates, Proteins, Nucleic acids and Lipids.
Carbohydrates are sugar molecules such as Glucose, Galactose Maltose, Fructose, Sucrose, Lactose, and Starch.Protein structures are of four types primary, secondary, tertiary, and quaternary structure. Histone is a kind of a protein. Nucleic acids include DNA and RNA.Biomolecules present in chromosomes are nucleic acid (DNA and RNA) and Histone protein. Hence option “G” is correct.

Mount Everest is the world's highest mountain. It is 29,028 feet (9km) above sea level. It is located in the Himalayas between Nepal and China. But now that we have sonar, we know about Mauna Kea. Mauna Kea is on Hawaii Island. It is 13,448 feet (4km) above sea level. From its base on the ocean floor, it is 33,796 feet (10km)! Should we still consider Mount Everest to be the highest mountain? Why or why not?
Answer:
I think Mount Everest should still be called the highest mountain
Explanation: Based on tradition, mountains are not measured from their bases but from sea level so considering this Mount Everest should still be called the highest mountain in the world. However despite this, some may say it should not be.
Explain Mendel’s laws in genetic terms, that is, in terms of chromosomes, genes, and alleles.
Mendel's First Lawstates that for the pair of alleles an individual has of some gene (or at some genetic locus), one is a copy of a randomly chosen one in the father of the individual, and the other if a copy of a randomly chosen one in the mother, and that a randomly
A parent may have two distinct alleles for a certain gene, each on one copy of a given chromosome. Mendel's second law, the law of segregation, states that these two alleles will be separated from each other during meiosis.

Which of these is NOT a reason for mitosis in humans?
to grow
to make sperm and egg cells for reproduction
to heal
to replace dead cells
Answer:
to heal..
Explanation:
Answer: To make sperm and egg cells for reproduction
Explanation:
Cell division happens in humans and most other animals by mitosis and meiosis. When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides through meiosis, it produces four cells, called gametes. Gametes are also called sperm in males and eggs in females.
Unlike in mitosis, the gametes produced by meiosis are not clones of the original cell, because each gamete has exactly half as many chromosomes as the original cell.
In healing and growth, mitosis occurs beacuse the body clones cells to produce more of the exact same kind of that body part.
