Explanation:

The clown fish is able to make its home in the poisonous sea anemone, but any other fish that comes along would be paralyzed and killed. The clown fish also seems to keep butterfly fish away from the anemone, as they eat its tentacles.Which term describes the relationship between the sea anemone and the clown fish?
a. parasitism
b. mutualism
c. commensalism
d. competition

Answers

The term that best describes the relationship between the sea anemone and the clownfish is known as mutualism. Thus, the correct option for this question is B.

What is Species interaction?

Species interaction may be defined as a type of process through which the population of one species interacts with the population of other species that live in the same locality at a given time for various purposes.

According to the context of this question, the clownfish is able to make its home in the poisonous sea anemone and in return clownfish keep butterfly fish away from the anemone, as they eat its tentacles.

So, both species are mutually favoring and support each other. This type of species interaction is known as mutualism as it is a type of +,+ interaction where both species are benefitted.

Therefore, the term that best describes the relationship between the sea anemone and the clownfish is known as mutualism. Thus, the correct option for this question is B.

i think the answer is b. mutualism

this is becuase the sea anemone provides a safe home for the clown fish while the clownfish keep the butterfly  fish away from the anemone, as they eat its tentacles. so both organisms are benifitting from this relationship therefore it is mutualism.

please mark as brainliest if i am correct :) thanks sm

. Evergreens are plants that maintain their leaves in all seasons and include trees such as

Answers

Evergreens are plants that maintain their leaves in all seasons and include trees such as Conifers, Broadleaf evergreens and Evergreen shrubs

What are these trees?

Conifers: Conifers are the most common type of evergreen tree. They have needle-like leaves that are arranged in clusters. Some common conifers include pines, firs, and spruces.

Broadleaf evergreens: Broadleaf evergreens have broad, flat leaves that are arranged in opposite or alternate patterns. Some common broadleaf evergreens include holly, rhododendron, and laurel.

Evergreen shrubs: Evergreen shrubs are smaller than trees, but they still retain their leaves in all seasons. Some common evergreen shrubs include juniper, boxwood, and holly.

Evergreens are plants that maintain their leaves in all seasons and include trees such as Kauri, Sequoia, Coconut, Real Yellowwood, Australian Tree Fern, Live Oak, Shamel Ash, Eucalyptus, Southern Magnolia and Pine etc.

Further Explanation

Evergreen plants

In organic science, an evergreen is a plant that has leaves during the time that are constantly green. This is genuine regardless of whether the plant holds its foliage just in warm atmospheres, and appears differently in relation to deciduous plants, which totally lose their foliage throughout the winter or dry season.

Types of Evergreen trees

They are of different types some of them are given below.

Cypress Trees

They can be perceived by their pyramidal molded little, adjusted, woody cones, shoots and scale-like leaves. Their foliage can extend from yellowish-green to green or a grayish shading. They can arrive at developing statures of up to 60 feet.

Spruce Trees

They are pyramidal trees than can be known for their cone-like structure and whorled branches. The needles on these trees are appended to the branches in a winding like development. Tidy trees can extend from 5 feet tall for diminutive person trees, and to statures of 60+ feet for bigger trees.

Cryptomeria Trees

These trees are known for their attractive cone-like shape and rich, ruddy darker bark which regularly strips off in strips. These enormous trees can arrive at statures of 35 to 45 feet. They additionally have needle-like leaves that structure spirally scales on their branches.

Bamboo Grass

Bamboo is a lovely tropical evergreen that is a piece of the perpetual grass family. They're one of the quickest developing evergreens around the world. They can be perceived by their empty stems that develop in groups.

(a) It is possible to measure a patient’s heart rate by either palpating their peripheral pulse, by observing their ECG, or by listening for the lub-dup through a stethoscope. However, patients with atherosclerosis of the femoral artery may not have a pulse in the popliteal artery or dorsalis pedis of the foot. Does this mean that they will also lack a heart beat (lub-dup) or QRS complex? Explain the relationship between a heart beat, pulse, and QRS complex. (B) Why is there a delay between systole of the ECG and the resulting pulse felt in the finger (R-Pulse)?

Answers

b)When you listen to the heart sounds, you are hearing the flow of blood which stops abruptly when a heart valve closes. This produces the "lub-dub" sounds. 1st heart sound (when the Mitral Valve closes) as the ventricle contracts (systole) and then 2nd heart sound (when the Aortic Valve closes) and the ventricle starts to fill again (diastole)
The pulse is the wave of pressure you can feel through the artery walls. This denotes systole.
The ECG's QRS complex is the electrical signal that tells the Ventricles to contract. You can see that the QRS occurs right at the beginning of systole and triggers Isovolumetric contraction.
So the QRS on the ECG, the pulse wave you can feel (ie. the rise in aortic pressure) and the 1st heart sound all signify SYSTOLE.
there a delay between systole of the ECG and the resulting pulse felt in the finger (R-Pulse) because it takes a little bit of time for the pressure to transmit through the body, as the finger is not on the heart (if it was there would be no delay)

Which class of organic molecules provides long-term energy storage. a. carbohydrates b. proteins c. starches d. lipids

Answers

Answer: D - Lipids
Lipids provide a long term energy storage because they contain longer C-H bonds compared to the other organic molecules, making it easier for them to store larger amount of energy. Moreover, upon burning they produce twice the amount of calories compared to that of the carbohydrates.
