The cell membrane allows the transportation of materials in and out of plant cells, although the cell wall is also key for these processes.

The cell wall is a rigid structure located outside the plant cell that protect it against friction and osmotic stress.

The cell wall is also required to transport substances in and out of the plant cell by pores present in this structure.

Moreover, the cell membrane is a physical barrier that allows the interchange of nutrients and waste materials between the cell and its surrounding environment.

In conclusion, the cell membrane allows the transportation of materials in and out of plant cells, although the cell wall is also key for these processes.

The cuticle is the most exterior layer of arthropods' tegument. It is secreted by the epidermis and develops right over it.

It is composed of two main layers,

The cuticle is mainly made of chitin, and its function is to protect the organism's body and avoid dehydration.

Because it avoids dehydration it is believed that arthropods had such an evolutive and adaptative successful in their transition from water to the land.

The community along with the biotic and abiotic factors makes the ecosystem. In the ecosystem, 10% of the energy primary consumers absorb is lost as heat. Thus, option D is correct.

An ecological pyramid is the graphical presentation of the organism and the flow of energy at each trophic level. The trophic level constitutes the producers and the consumer.

The flow of energy follows the 10% energy rule where each trophic level loses and gains only a certain amount of heat. The heat is lost as excretory products in the environment.

The maximum amount of energy is gained by producers which passes to the primary consumers (10%), secondary consumers (1%), and the upper trophic level.

Therefore, option D. primary consumers absorb only 10% of energy.

What elements are always present in protein?

A. radium, boron, fluorine, and chlorine

B. mercury, iron, lead, and aluminum

C. carbon, hydrogen, oxygen, and nitrogen ( ✔ )

D. neon, argon, krypton, and copper

Proteins are one of the primary constituents of living matter. They consist of long chains of amino acids, which are bonded together by peptide linkages and thus called polypeptides. There are about 20 amino acids, and the atoms most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulphur.

The elements that are always present in protein is carbon, hydrogen, oxygen, and nitrogen. The correct option is C.

Proteins are large molecules made of amino acids that are crucial for a number of biological processes in living things. Proteins usually contain the following elements: carbon (C), hydrogen (H), oxygen (O), and nitrogen (N).

These components serve as the fundamental building blocks of amino acids, which are joined by peptide bonds to form protein chains.

The fundamental components that are consistently present in all proteins are carbon, hydrogen, oxygen, and nitrogen, while other elements, such as sulphur (S) and phosphorus (P), can also be found in some proteins.

Thus, the correct option is C.

Explanation:

To answer this question, we need to define the given answers and look at what the owl eats via the diagram. Then we will decide what the owl is considered to be.

Here are simple definitions for the given answers:

       Carnivore: eats only animals

       Scavenger: eats dead organisms

       Omnivore: eats both plants and animals

       Herbivore: eats only plants

Next, we will look at what the owl eats via the diagram. See attached. The owl eats frogs, snakes, squirrels, rabbits, and mice (these might not be the exact animals, I am assuming based on the picture). All of these are animals that appear to be alive, meaning the owl is a carnivore.

C, a mutation in the skin cells of an adult mouse, is the occurrence that would be most likely to lead to an evolutionary shift in the mouse population on the island.

Genetic variety, which is the foundation of evolution, is mostly produced via mutations. Mutations can result from external sources like radiation or chemicals or spontaneously arise as DNA is replicated during cell division.

A change in a mouse's genes resulting from a mutation in its mature skin cells might be passed on to the mouse's progeny. The other things on the list wouldn't affect the population of mice in an evolutionary way. Event A, a predator on an island killing and devouring 50 mice, would cause the population to decline.but would not result in an evolutionary shift due to size.

Even though Event B, a storm that drowned roughly 50 mice over the whole island, reduced the population number, it had no evolutionary impact. Even though Event D, a drought that reduced and altered the mice's food supply, did not affect evolution, it may have changed the mice's behaviour, such as making them more competitive for food.

The population would grow as a result of Event E, a mating couple of mice having an abnormally high number of offspring, but no evolutionary change would result.

In conclusion, C, a mutation in an adult mouse's skin cells, is the scenario that would most likely result in an evolution of the mouse population on the island.mouse. The main cause of the genetic variety that underlies evolution, mutations can alter the genes that are handed down to the next generation. The other things on the list wouldn't affect evolution.
