Answer:
1. Epidermis (outermost)
2. Skin
3. Cuticle
4. Stomata
5. Inhibit water loss and protect the leaf
Explanation:
1. The dermal layer of the plant is called Epidermis which is the outermost layer of the plant leave made up of several
2. Ther dermal layer in plants is like skin of human which also made of three different layer knwon as epidermis (outermost), dermis (middle) and subcuatneous (deepest).
3. A waxy barrier present at leaf surface is called cuticle which provide protection against mechanical injury to the plant.
4. Stomata are the tiny holes present in the leaf surface that regulate the exchange of gases and water loss through its opening an dclosing mechanism.
5. The main function of epidermis is to provide protection to the plants from any mechanical injury and prevent water loss.
Hence, the correct answers are Epidermis (outermost), Skin, Cuticle, Stomata, Inhibit water loss and protect the leaf

- Flood irrigation uses more water than necessary, drip irrigation is better.
- Clear cutting is not necessary, nor is it practical. Logging should instead be done using methods that create sustainable yield--which ensures that no more is harvested than can be naturally replenished (Dadd)
-A sustainable fishery is one that is harvested at a sustainable rate to ensure that the fish population does not decline over time as a result of fishing methods or practices. ... Overfishing, as well as issues such as individual fishing quotas and the curtailment of destructive and illegal fishing practices are addressed.
Explanation:
Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
Answer:
The correct answer is ''All three are caused by disparate genes, but each gene was found to contain repeats of a unique trinucleotide sequence.''
Explanation:
Four groups of trinucleotide repeats related to DNA expansion have been characterized in the human genome. CGGI GCC, CAGIGTC, CTGIGAC and recently GW CTT sequences. The CGGl GCC sequences are usually located in the noncoding regions of different genes and when expanded they associate with fragile sites on the chromosomes. The CAGIGTC repeats are part of the coding region and are related to different neurodegenerative disorders. You can try to make a classification depending on the unit that is repeated, having on one side a group that are caused by repeats of the CAG trinucleotide (cytosine, adenine, guanine). Huntington's disease (HD) is a progressive disorder of motor, cognitive and psychic function. The disease is inherited in an autosomal dominant manner, and is caused by the expansion of CAG trinucleotide repeats in exon 1 of the gene called huntingtin (HTT or IT-15). Unstable mutations have also been found in which the repeat unit does not is composed of three nucleotides, if not four, such as type 2 myotonic dystrophy, where the tetranucleotide CCTG repeats. Fragile X Syndrome consists of an abnormal expansion of the cytosine-guanine-guanine trinucleotide (CGG) in the FMR1 gene, which prevents intellectual disability and also influences the formation of connective tissue
