What part of the respiratory tract is considered the respiratory zone?
A. Bronchioles
B. Larynx
C. Trachea
D. Alveoli
Answer:
D. Alveoli
Explanation:
Functionally, the respiratory system is separated into a conducting zone and respiratory zone:
Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.
Answer:
Yep, the correct answer is D.) Alveoli

As water passes into the guard cells, the pore opens. explain why.
Answer:One of the most important functions of guard cells is to control the closing and opening of the stoma/pores. While the opening of these pores allows water to be released into the environment, it also allows carbon dioxide to enter the cell for photosynthesis (as well as the release of oxygen into the environment).
Explanation:
Answer: guard cells are a pair of cells that surround each of the stoma openings. to open the cells, they have to be triggered by one of many possible environmental or chemical signals. these can include more sunlight or higher than normal levels of carbon dioxide within the cell.
Explanation:
they open to regulate the gas and moisture exchange, hope that this is what you were looking for :)

What is currently happening with Mount Etna?
Answer:
As Italy’s National Institute of Geophysics and Volcanology (INGV) explains on a recent blog post, the nascent eruption began on the night of May 29. Starting off by producing a thick column of ash rising from the New Southeast Crater, it gave way on May 30 to a far more lava-heavy display in the area, featuring two fissures blenching out lava.
Answer:
There is currently no eruptive activity at the volcano involving fresh lava and monitoring signals do not suggest an immediate change likely; only a weak thermal anomaly continues to be present from the southeast crater complex.
Explanation:

Explain why the forest ecosystem is a system.
Answer:
Like all ecosystems, forests consist of many interacting parts. They include living organisms such as plants, animals, and fungi. Forests also include non-living components that these organisms depend on, such as the soil and climate. As stated in the article, one change, such as pollution, can cause a ripple effect through the ecosystem. Dying lichens are one of the earliest signs of pollution. In turn, the loss of the lichens can cause a decline in species that rely on the lichens for survival.

Identify the disorders described. immune system overreacts to an antigen part of the immune system does not function properly the body's immune system attacks its healthy cells, mistaking them for pathogens masses of cells form and steal nutrients from healthy cells
Answer: 1: allergic disorders
2. Immunodeficiency disorders
3. Autoimmune disorders
4. Cancers
Immune system overreacts to an antigen part of the immune system does not function properly the body's immune system attacks its healthy cells, mistaking them for pathogens masses of cells form and steal nutrients from healthy.
What do you mean by Allergy?Allergy may be defined as a reaction by our immune system to something that does not trouble most other people. It affects a person more specifically.
When a person gets affected by any allergy, the immune system of that person may overreact by producing more antibodies. These antibodies attack the allergen particles and cause adverse symptoms.
A person who has allergies has them because his or her body over reacts to a material that would otherwise be ignored. It is an overreaction of the immune system triggering a immune attack response that is unneeded.
Therefore, a person who has allergies has a compromised immune system because the body's immune system overreacts to an antigen.

Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait
are called ______. A) phenotypes B) alleles
C) DNA
D) mutations E) genotypes
Answer:
The answer is B) alleles
Explanation:
Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.
What do you mean by traits?Traits may be defined as the appearance or manifestation of the desired characters. Traits are also known as phenotypes.
Every factor or gene has two alternative copies, one comes from the father and one comes from the mother. These two copies are present in the same location on the homologous chromosome. They are known as alleles of each other.
Therefore, Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.

Which of the following is always true of two organisms in
the same taxonomic class?
A.They can breed with one another
B.They have certain physical features in common
C.they evolved at the same time
D.they live in the same ecosystem
Answer:
they can breed with one another, they have certain physical features in common, they evolved at the same rate, they live in the same ecosystem. Lions and house cats share common features, but cannot breed with one another.
Explanation:
They share a common ecology, they may breed with one another, share some physical characteristics, evolve at the same rate, and inhabit the same ecosystem, hence option D is correct.
What are the taxonomic classes?If two species are members of the same class, they are also members of the same higher-level taxon. They share the same phylum and kingdom in this instance.
Kingdom, phylum or division, class, order, family, genus, and species are the seven main taxonomic ranks.
The taxon with the greatest number of species is the kingdom. In taxonomy, it is the broadest category into which the creatures can be divided.
The classification of five kingdoms was made by R.H. Whittaker. The kingdoms of Monera, Protista, Fungi, Plantae, and Animalia are included in this classification.
Therefore, option D is correct.
