Answer:
C. Both A and B describe errors in the statement.
Explanation:
In fossilization i.e formation of fossils, two terms are used as follows: permineralization and petrification.
- Permineralization is a process whereby the pore spaces of an organism's remains are filled with mineral matter that precipitates from lake and ocean solutions.
- On the contrary, petrifaction or petrification is the process whereby a once-living tissue (matter) are REPLACED by minerals, hence, preserving the organism's structure by turning it into a stone (petros).
According to this question, the student mixed up their definitions by giving the definition of permineralization instead, however, options A and B have described the errors associated with the statement.
2. Oxygen is carried in the blood by the:
Answer:haemoglobin
Explanation:
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.

simple cycle because of three reasons.
A.
B.
C.
Answer:
A. Small size.
B. A single cell or unicellular.
C.it has one chromosome which is not true and it is called plastid.
Explanation:
This is because prokaryote are unicellular organisms that lack nucleus and membrane bound organelles. The are smaller in size compare to eukaryotic, which have large surface to volume ratio. They lack mitochondria, Golgi apparatus, endoplasmic recticulum, e t.c. They have only one chromosomes which is not even a true one and it is called plastid. Examples of prokaryote include bacteria.

In pea plants, the allele that produces purple flowers (P) is dominant to the allele that produces white flowers (p), and the allele that produces tall plants (T) is dominant to the allele that produces short plants (t). Two pea plants are crossed and produce 521 offspring, and the results of this cross are shown below:
Phenotype Number of offspring
Tall with purple flowers 291
Short with purple flowers 97
Tall with white flowers 101
Short with white flowers 32
Which cross would MOST LIKELY lead to this outcome?
Pptt × ppTt
pptt × PPTT
PpTt × PpTt
ppTT × PpTt
Answer: PpTt x PpTt
Explanation:
The cross PpTt × PpTt leads to the phenotype Number of offspring Tall with purple flowers 291 Short with purple flowers 97 Tall with white flowers 101 Short with white flowers 32, hence option C is correct.
What is a dihybrid cross?Two creatures that are identically hybrid for two characteristics are said to have mated to create a dihybrid cross. When an organism is heterozygous, it signifies that there are two distinct alleles present at a certain genetic location.
An attempt in producing two creatures that are identical hybrids for two qualities is a dihybrid cross.
The people with this sort of character are homozygous for that particular trait.
Therefore, to put it another way, a dihybrid cross is a union of two organisms that are heterozygous for two separate features, hence option C is correct.

which cells divide more often than other cells?
Help
That means we lose around 50 million cells every day. This is a lot of skin cells to replace, making cell division in skin cells is so important. Other cells, like nerve and brain cells, divide much less often.
Why would some fish prefer colder/clearer waters and some warmer/turbid waters?
Answer:
Cold water has the ability to hold more oxygen than warm water. Hot summer temperatures can heat water so it won't hold enough oxygen to maintain fish life.

How does DNA copy itself
Explanation:
DNA unwraps itself before cell division. It helps that each side of the double helix is in opposite direction of the other. Then the DNA polymerase travels around each strand and binds the complementary nucleotides (DNA's building blocks). The process is called DNA replication.
What is one way during the G0 phase that a mistake during the cell cycle could result in problens for the G0 phase?
The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state.This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle.
Which muscle cells are often considered as G0 phase cells?Poly-nucleated muscle cells that do not undergo cytokinesis are often considered G0 phase cells.The G0 phase is seen as a distinct and quiet stage that occurs outside the cell cycle.
Mitosis is the procedure with the aid of which a mobile replicates its chromosomes after which segregates them, producing two identical nuclei in training for mobile division. Mitosis is generally followed by way of same department of the mobile's content material into daughter cells that have identical genomes.
The two phases of cell cycle are interphase in which DNA replication occurs, 3 stages of interphase are: G1 phase, S phase and G2 phase and mitotic in which division occurs phase. Mitosis occurs after the completion of DNA replication and doubling of chromosome number and cell contents and after mitosis, two daughter cells are produced of equal number of chromosomes.
Therefore, The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state.This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle.

The common North Carolina geological feature is pictured in the graphic below is river basin. Thus option A is correct.
What is river basin?River basin is defined as the amount of land over which surface run-off falls into the sea via streams, rivers, and lakes.
A drainage basin is defined as a section of land where all flowing surface water flows to a single place, such as a river mouth, or into another body of water.
River basin is also defined as an ecological phrase referring to the area of land surrounding a river from which all water drains.
It is the land area drained by a river and its tributaries
