a hypothesis tends to go like “if [action] then it should [desired result]” if that makes any sense.

So if that statement were reworded to a hypothesis it would be like “If sunflowers are planted in soil and given plenty of sunlight and water (action) it will grow and thrive (desired result).”

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​

Answers

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.

What part of the respiratory tract is considered the respiratory zone?
A. Bronchioles
B. Larynx
C. Trachea
D. Alveoli

Answers

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

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.

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.

In what ways did Charles Lyell impact Charles Darwin’s theory of evolution? What type of relationship did Darwin have with Charles Lyell? How did Darwin learn about Charles Lyell's ideas?

Answers

Answer:

They both believed that continuous and gradual change is law of nature

Explanation:

Charles Lyell's “Principles of Geology “ encouraged Charles Darwin to think of evolution of living organisms as a slow process just like the slow geological processes taking place since millions of years. As per Charles, the slow and little contribution of continuous geological events shaped the present geological attributes of the earth. Likewise Charles Darwin’s theory of evolution also earmarked accumulated effects of small gradual changes over immense spans of time. They both believed that continuous and gradual change is law of nature.
