Adaptation, inherited traits that increase an organism's chance of survival, also determine an organism's niche.
Adaptations are features or behaviors exhibited by organisms and are usually common in a population. Adaptations evolve by natural selection and they fit organisms to their environment. Adaptations have functional roles and may be physiological, structural or behavioral. The long necks of giraffes for feeding in the tops of trees, and the long canine teeth of carnivores are examples of adaptation.
Answer: Solution 2 because the single substrate easily get transformed into products at the active site of any of the 100 enzymes.
Explanation:
Since Solution 1 has 1 enzyme to 100 substrate while Solution 2 has 100 enzyme to 1 substrate, catalysis of the single substrate to product will be greater in Solution 2 as the enzyme will compete to quickly transform the single substrate in its active site unlike solution 1 will 100 substrates taking more time.
Answer:
Epiblema, cortex, endodermis, pericycle
Explanation:
The outer most layer of monocot root is rhizodermis or epiblema which has compactly arranged tubular cells and unicellular root hair as their extension. Just beneath the epiblema are multiple layers of parenchymatous cells with ample intercellular space, it is cortex. The inner most layer of cortex forms endodermis which has compactly arranged barrel shaped cells with casparian strips at their anticlinal wall. The uniseriate layer of thin walled parenchymatous cells, present below endodermis, which are sclerified in old roots makes pericycle. The vascular bundles are present as alternating strands of xylem and phloem, the discrete xylem strands alternated with phloem strands. The central parenchymatous cells form pith.
Answer:
GnRH
Explanation:
GnRH stimulates pituitary secretion of luteinizing hormone (LH) and follicle stimulating hormone (FSH). LH and FSH then stimulate the ovaries, resulting in the growth of secondary preantral follicles and ovulation.
Although some release hormones are also secreted in pulses, GnRH is unique because pulsed gonadotroph stimulation is necessary for normal LH and FSH synthesis and secretion, while continuous infusion of GnRH - or the use of such an agonist hormone that stimulates continuous infusion - results in negative modulation of gonadotropic responsiveness to GnRH. This property is clinically used to treat hormone-responsive conditions such as endometriosis and precocious puberty.
Answer:
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilization and sustain our economies.
