Describe the structure and function of a root hair cell

Biology
1 answer:
Nadya [2.5K]3 years ago

Root hair cells absorb minerals and water from the soil.


The water absorbed by the root hair cells passes through the plant in xylem tubes, to then reach the leaves. The energy from the sun is then used to convert water(H2O) into hydrogen (H) and oxygen(O2).

Check all of the statements that are true regarding keratinized stratified squamous epithelium.
strojnjashka [21]

Answer;

-Keratinized stratified squamous epithelium forms the epidermis of the skin.

-In keratinized stratified squamous epithelial tissue, the cells on the apical (outer) surface are dead.

Explanation;

-Stratified squamous epithelium is a type of tissue found covering and lining parts of the body. Stratified squamous epithelium may be keratinized or nonkeratinized. Non-keratinized surfaces must be kept moist by bodily secretions to prevent them from drying out.

-The cells on the surface of stratified squamous keratinized epithelium are very flat. Not only are they flat, but they are no longer alive. They have no nucleus or organelles. They are filled with a protein called keratin, which is what makes our skin waterproof.

Which of the following situations accurately describes a difference between a food chain and a food web?
hoa [83]

“A carnivore eats both a rabbit and a mouse in a food web” accurately describes a difference between a food chain and a food web.

 

<span>A food chain is a series of events in which one organism eats another and obtains energy. An example could be a forest food-chain. The bear is the top of the food chain. The bear eats a coyote. The coyote ate the rabbit. The rabbit ate the grass. Since the grass can't technically eat anything, it's the bottom of the food chain and the food chain ends. </span>

 

<span>A food web is a diagram showing the various different plants and animals in an ecosystem in relation to each other. It encompasses many consumers of each different level, acknowledging that one predator may eat several different kinds of prey, and that one kind of prey may be eaten by several kinds of predators. There are many food chains within a food web, and one creature is not necessarily at the top of the hierarchy. </span>

 

The correct answer between all the choices given is the second choice or letter B. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
