Answer: When the diaphragm contracts, it moves inferiorly toward the abdominal cavity, creating a larger thoracic cavity and more space for the lungs. Contraction of the external intercostal muscles moves the ribs upward and outward, causing the rib cage to expand, which increases the volume of the thoracic cavity.
The movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.
The ventilation in human lungs or pulmonary ventilation is defined as the process of intake of air during inhalation, and expiration as the release out of air. It is also termed as breathing.
What is the mechanism of pulmonary ventilation?The lungs are present in the thoracic cavity, with the diaphragm below the lungs separating the thoracic cavity from the abdominal cavity. The rib cage is present outside lungs and prevent them.
Inhalation process in pulmonary ventilationThe inhalation is the process of taking in air. The increase in the volume of lungs results in the increased movement of diaphragm to the abdominal cavity.
The intercostal muscles move upwards and the rib cage move outwards. Thus, the air is inhaled in the system.
Exhalation process in pulmonary ventilationThe exhalation of air is performed antagonist to the inhalation. The relaxation of diaphragm and the movement of rib cage results in the decreased volume of the lungs, and the air is expelled.
Thus, the movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.

A small primate is observed in South America. It has a prehensile tail, spends most of its time in the trees, and is fairly small. What type of primate is it? HighLighter PopupUnderline Selected TextGreen Color HighlightOrange Color HighlightYellow Color HighlightBlue Color HighlightPink Color HighlightRemove Color Highlight A. Lemur B. Tarsier C. New World monkey D. Old World monkey
Answer:
C
Explanation:yeah
The correct answer is New World monkey as is observed in South America. It has a prehensile tail, spends most of its time in the trees, and is fairly small.
On one hand, a few species of New World monkeys own prehensile tails, which means they are able to use their tails to understand or maintain directly to objects (2). Their tails can resource those monkeys in locating and consuming meals withinside the cover in addition to transferring among the trees, as their tails offer greater help and balance.
The formal time period for the taxonomic organization containing all of the New World Monkeys (NWMs) is Platyrrhini. The NWMs diverged from the Old World monkeys and apes (Catarrhini) round forty million years ago (Perelman et al. 2011). Ancestral species are idea to have migrated to the Americas on rafts of plants or through island hopping (Fleagle 2013). The extant species of NWMs are presently labeled into 5 families, twenty genera, 156 species, and 204 taxa. However, the taxonomy of numerous taxa is debated withinside the literature and, therefore, this type is concern to change.
What is the New World monkey living area?
Many of the monkeys scampering across the forests of Central and South America have some thing unique on their butts-- a further hand. Well, now no longer exactly. It's a prehensile tail-- a greedy appendage that enables the animals navigate the tall and treacherous cover on the lookout for end result and leaves .
Hence concluded that the New World monkey have a prehensile tail, spends most of its time in the trees, and is fairly small.

What are the answers for questions 4 and 5?
Answer:
4. D (enzymes 1 and 3 works equally well in an acidic and alkaline environment respectively)
5. C. 2; 7; 9.5
Explanation:
The image attached to this question shows a graphical representation of the pH ranges for three enzymes. According to the image;
- Enzyme 1 reached its peak reaction rate at pH 2 (acidic)
- Enzyme 2 reached its peak reaction rate at pH 7 (neutral)
- Enzyme 3 reached its peak reaction rate at pH 9.5 (basic)
This result means that enzymes 1, 2 and 3 will work well and effectively at an acidic, neutral and alkaline environment respectively. Likewise, the optimal pH level for enzymes 1, 2 and 3 are 2; 7; and 9.5 respectively.

How are genetic mutations passed from parent to offspring?
Answer:
Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations.
I hope it's helpful!
Answer:
★ Mutated gametes (sex cells) fuse to create offspring.
Genetic mutations or germline mutations can be defined as a permanent change in the DNA sequence of germ cells (cells, which form ovum and sperm). These mutations can pass from one generation to other when a mutated sperm or mutated oocyte (gametes) get fertilized with another oocyte or sperm.
A germline mutation, present in a single-celled zygote will present in all cells of a muticellular organism, a single-celled zygote divides and produces all of the cells in that organism.

about how traits are passed on to offspring. One conclusion became known as the Law of
Segregation. The illustration below shows how this law operates.

Parent 2
Offspring 1 Offspring 2 Offspring 3 Offspring 4
Which conclusion can you make based on Mendel's work as shown in the diagram?
Parent 1 has the dominant trait
Parent 2 has the dominant trait.
The offspring inherit traits only from Parent 1.
The offspring will not pass on the trait, inherited from Parent 2, to their offspring.
