Answer:
e. cutin
Explanation:
Plant exhibit many variations to withstand the temperature variations, desiccation and increased UV exposure which are some of the factors associated with land habitat. Cutin is a waxy substance that is found in the outer walls of the epidermal cells of plants. Cuticle in plants serves to make the outer most covering of aerial parts of the leaves and non-woody stem of herbaceous plants. The cuticle is made of cutin.
Cutin serves to protect the plant’s aerial surfaces from excess water loss. It also filters the excess UV light and thereby protects the underlying plant parts. The thickness of the cuticle varies in different plants depending upon the environmental conditions. The leaves of plants adapted to hot, dry climates have thick cuticles. The thickness of the cutin layer also varies in different parts of a plant. For example, the upper epidermis of leaf generally has a thicker cuticle than the shaded and relatively cooler lower epidermis.
Answer:
The relationships that organisms have with one another are an important part of the balance among species within ecosystems. Which type of symbiotic relationship occurs when ecological niches overlap and multiple organisms seek the same resources?
Competition
Explanation:
Competition entails when ecological niche overlaps and many organisms seek for the same resorces hence leads to competition and overcrowding.
Muscles and human skeleton are very much connected with each other.
<h3><u>Explanation:</u></h3>
Muscles form one of the 5 systems of our body. They consists of both the skeletal muscles as well as the smooth muscles of our body. While the smooth muscles are the part of the organs, the skeletal muscles are attached with bones either directly attached, or they are attached with the bones by means of tendons. These muscles are formed of cells called sarcomeres and they are the structures which make the bones move. Bones ars like the rods and muscles are like hydraulics. So they are collectively called as musculoskeletal system.
Skeletal system is referred to as the collection of each and every bones of our body which is roughly 206 bones, and their organization in body helping us to stand and move.
Answer:
The answer to your question is single replacement.
Explanation:
Single replacement In this reactions, one element replaces an element of another molecule.
Double replacement In this reactions the metal of one molecule replaces the metal of another molecule and vice versa.
Synthesis here, two molecules combine to form a new one.
Decomposition One molecule form 2 or more molecules
Combustion one molecule that has carbon reacts with oxygen and produces carbon dioxide and water.
Golgi apparatus, endoplasmic reticulum, and ribosomes
