What is the graphical representation of age structure known as?
OA.
age group
OB. age graph
Oc. age scale
OD
age pyramid
Answers
Answer:
The graphical representation of the age structure is known as age pyramid (option D).
Explanation:
The age pyramid or more properly called population pyramid groups all the individuals of a population, distributing them by age and sex. The name is due to the fact that, in general, the bar graph resembles a pyramid.
The age groups are distributed in the pyramid by age from lowest (bottom) to highest (top), with the sexes forming the sides of the pyramid.
In emerging countries the population is relatively young, which makes the base of the pyramid wide, narrowing as it moves up to the upper age groups.
Age group, age graph or age scale do not correspond to the population graph where the age and sex structure of a population are expressed.

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
Answers
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.

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?
Answers
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.
Multicellular organisms contain organ systems. Which of the following BEST describes the organs in an organ system?

O
D. The organs in an organ system work together to perform all the functions a multicellular organism needs to maintain homeostasis.
Answers
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.
Which best describes the relationship between digestion and cellular respiration? O A. Digestion breaks foods down to simple sugar molecules, and respiration uses the sugar molecules to produce energy. O B. Digestion creates nutrients from food particles, and respiration uses the nutrients to produce energy. O C. Digestion releases oxygen molecules from food, and respiration uses oxygen molecules to produce energy. D. Digestion produces waste materials, and respiration uses the waste materials to produce energy.
Answers
Answer:
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products

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.
