Answer:
A: X Chromosome
B: Centromere
C: P Arm - Short Arm Structure
D: Q Arm - Long Arm Structure
E: DNA Molecule
F: Chromatids
Explanation:
The X chromosome does more than determine sex. We inherit one copy of each chromosome from each parent, and the different versions of genes present on each copy, called alleles, help determine our individual characteristics.

Multicellular organisms contain organ systems. Which of the following BEST describes the organs in an organ system?
о A. The organs in an organ system are made up of similar cells.
O
B. The organs in an organ system are made up of similar tissues.
C. The organs in an organ system work together to perform a specific function.
O
D. The organs in an organ system work together to perform all the functions a multicellular organism needs to maintain homeostasis.
Answer:
C. The organs in an organ system work together to perform a specific function.
Explanation:
The definition of an organ system is a "group of organs that work together as a biological system to perform one or more functions". Each organ in a system does a different job in order to achieve the same goal. For example, the stomach breaks down food, and the intestines gather nutrients but the goal of both is to digest food.
A botanist crosses two pink-flowered plants. The cross involves alleles that were not clearly dominant or recessive and could make red, pink, and white-flowered plants. If four plants are produced from the cross, what is the expected number of white-flowered plants?
Answer:
1
Explanation:
According to the information in this question, a gene coding for flower color in a plant is involved. The allele for red color (R) is incompletely dominant over the allele for white color (r) to form an intermediate phenotype/color i.e. Pink that is heterozygous (Rr) for the gene.
If two pink plants are crossed i.e. Rr × Rr, each parent will produce R and r gametes. Using these gametes in a punnet square (see attached image), the following offsprings will result: RR, Rr, Rr, and rr.
Out of these four offsprings;
1 RR is red : 2 Rr is pink: 1 rr is white
Hence, If four plants are produced from this cross, according to this question, the expected number of white-flowered plants will be 1 out of 4.
Infer If the rock layers shown above hare
not been disturbed, what type of dating
method would help you determine which
layer is oldest? Explain.
Answer:
radiometric dating methods
Explanation:
The oldest rock layer will be at the very bottom, and as time goes on, more layers will form making the top layer the youngest layer and the bottom layer the oldest. This method can determine the amount of radioactive decay of certain elements which can help them make a geologic time scale.

In contrast, the human skull's forehead rises immediately from the brows. A prominent nasal bone in the human skull between the eyes contrasts sharply with the flat curvature that leads to the chimp nasal hole.
In comparison to human cranial anatomy, apes have a more projecting face, a larger brow ridge, a longer face, and larger teeth in the front than in the back.

Explain the difference between an invasive species and a nonnative species.
Answer:
Non-native species spread by natural process or human activities. Most non-native or indigenous species are harmless. They are called exotic species. ... The main difference between exotic and invasive species is that exotic species is harmless to the ecosystem whereas invasive species is harmful to the ecosystem.
Explanation:
Answer and Explanation:
Invasive is a species of plant or animal that outcompetes other species causing damage to an ecosystem..
Non-native: a species that originated somewhere other than its current location and has been introduced to the area where it now lives..
Non-native species are also called exotic species..

describe the meaning of the phrase "cells are the basic unit of structure in all organisms" in your own words.
Answer:
Each organism has a basic unit of structure which are cells.
Explanation:
;)
Cells are regarded as the fundamental units of life in part because they come in discrete and easily identifiable packages.
What are cells?Cells are the fundamental building blocks of all life. Trillions of cells make up the organisms' body.
They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.
Nucleic acids, proteins, carbohydrates, and lipids are the four major classes of organic molecules found in all cells.
Cells are regarded as the fundamental units of life in part because they come in discrete and easily identifiable packages.
Like the walls of a house, all cells are surrounded by a structure called the cell membrane, which serves as a clear boundary between the cell's internal and external environments.
Thus, cells are the basic unit of structure of all organisms.

What conditions make for a violent volcanic eruption?
OA. Magma with low gas content
OB. Magma with low viscosity
OC. Magma with high silica content
OD. Magma that can flow easily
Answer: B
Explanation:
Magma with low viscosity
Magma that has high content of silica will lead to a violent volcanic eruption. Thus, the correct answer is option C.
What kind of magma results in violent volcanic eruption?Magma that has a high content of silica will have high viscosity. This is due to the bond formation between silicon and oxygen, forming a Si-O tetrahedron.
These tetrahedra combine with each other and result in polymerization which increases the resistance of the liquid to flow. This type of thick magma does not flow easily and will result in an explosive eruption.
High amount of silica causes a lot of gas to be trapped in the volcano. High-viscosity magma does not allow for the exsolution of gas bubbles.
Thus, the gas bubbles will be trapped inside and increase pressure on the magma column to explode. The trapped gas thus provides the driving force for the explosion.
Thus, the correct answer is option C.
