Bat and Dove​

Answers

Answer and Explanation:

Bats are mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium.

Their wings skeleton have the shape of finger/hands like a human.

Doves are the only family in the order Columbiformes. These are stout-bodied birds with short necks, and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants.

#teamtrees #WAP (Water And Plant)

Answer:

Doves have beaks and no teeth, whereas bats have jaw bones with sharp teeth. Although they both fly, Dove and bats feature different structures that allow them to take flight. Doves have rigid, feathered wings that they flap completely in order to fly.

have been heated by the sun?
A) cool and moist
B) hot and very dry
C) warm and moist
D) cold and dry
I need this today please help

Answers

Answer:

I'm pretty sure its c

Explanation:

Warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C is correct.

What are topical waters?

Topical waters are defined as water between the Tropic of Cancer (23.5° North latitude) and the Tropic of Capricorn (23.5° South latitude). In the Köppen climatic classification, a tropical climate is one in which the average monthly temperature is over 18°C. There is no winter season and there is more annual rainfall than annual evaporation.

A good illustration of this kind of fish is the goldfish. On the other hand, "tropical" or "warm water" fish require a water temperature that is optimal for their comfort and health. Although different species of fish have varying needs, tropical fish generally demand water that is between 76 and 80 degrees Fahrenheit (25 and 27 degrees Celsius).


Thus, warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C is correct.

Once blood tonicity is negatively impacted, can the consequences be reversed?

Answers

The process of forming ATP is? A) Digestion. B) Cellular Respiration. C) Metabolism. D) nutrition.

Answers

Answer:

[tex]\boxed {\boxed {\sf B. \ Cellular \ respiration}}[/tex]

Explanation:

First, let's analyze each process.

A. Digestion

This is the process of breaking down food.

B. Cellular respiration

This is the process of converting glucose and oxygen to carbon dioxide, water, and ATP.

C. Metabolism

This isn't really a process. It's the collection of all the chemical reactions in the body to keep the body functioning.

D. Nutrition

This term also isn't a process. Nutrition involves food, nutrients, and health.

We are looking for the process that forms ATP. Therefore, the best answer choice is B. Cellular respiration

The process of forming ATP is Cellular Respiration. Therefore option B is correct.

The process of forming ATP (Adenosine Triphosphate) is primarily through Cellular Respiration.

ATP is the main energy currency in cells, providing the energy needed for various cellular activities.

Cellular respiration is a series of metabolic reactions that occur in the mitochondria of cells, where organic molecules (such as glucose) are broken down and oxidized to release energy.

This energy is used to synthesize ATP from ADP (Adenosine Diphosphate) and inorganic phosphate (Pi).

Through cellular respiration, cells efficiently convert the energy stored in food molecules into a readily usable form of energy (ATP).

Which powers essential cellular processes, including muscle contraction, active transport, and synthesis of macromolecules.

Therefore option B Cellular Respiration is correct.

Read the excerpt from "Bone Detective," by Lorraine Jean Hopping. While the dentist worked on the tiger’s teeth, Diane made an alginate impression of one of its huge paws. Then, the dentist used two cupped hands to pull the tongue out of the big cat’s mouth. The heavily muscled organ was almost as long as her foot. With the dentist still holding the tiger tongue in both hands, Diane quickly went to work. The pink surface was rough, like sandpaper, but floppy and wet. She coated the top with alginate and waited for it to set. Her 15 minutes were almost up. The tiger, so calm and soft, would soon wake up and be dangerous again. Slowly and carefully, Diane peeled off the soft impression to avoid tearing it. Based on this excerpt, what is the author’s attitude toward Diane France? The author feels Diane is rough and impatient in her work with the tiger. The author feels Diane is skillful and careful in her work with the tiger. The author feels Diane is anxious and distracted in her work with the tiger. The author feels Diane is light-hearted and humorous in her work with the tiger.
