Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. ... In the energy-transduction reactions, solar energy is converted into chemical energy in the form of two energy-transporting molecules, ATP and NADPH.
Answer: Feed-back inhibition
Explanation:
When the final product of a biochemical pathway signal the inactivation of the starting materials of the pathway, feed-back inhibition is said to have occurred.
In this case, the amino acid, isoleucine signal the inactivation of its starting material. Thus, it is an example of feed-back inhibition
Answer:
1) Growth Pattern
2) Conical Shape
3) Needle-shaped leaves
4) Pine needles
5) Waxy coating
6) Chemicals
7) Dark-colored needles
8) Thick bark
9) Ever growing roots
10) Small surface area of pine needles
Explanation:
Pinus plants are coniferous plants that are evergreen and long lived. They are usually found in the Northern Hemisphere and few parts of the Southern Hemisphere. Their adaptations include;
1) Growth Pattern: Pinus plants grow very closely to each other, creating a dense setting that helps to preserve warmth.
2) Conical Shape: Their conical shape helps them shed off snow and helps them produce enough food through photosynthesis by staying green all year.
3) Needle-shaped leaves: This helps reduce moisture loss.
4) Pine needles: This reduces moisture loss through transpiration.
5) Waxy coating: The waxy coating of their pine needles protect them from harsh weather like drying winds. It also protects them from sap that cause may freeze.
6) Chemicals: The chemicals present prevent wildlife from eating them.
7) Dark-colored needles: This helps them absorb heat from the sun
8) Thick bark: Protects against cold
9) Ever growing roots: Their roots do not stop growing even in winter so there is always moist and nutrients.
10) Small surface area of pine needles: Their small surface area helps in moisture retention.
Answer:
The earliest civilizations developed between 4000 and 3000 B.C.E., when the rise of agriculture and trade allowed people to have surplus food and economic stability. Many people no longer had to practice farming, allowing a diverse array of professions and interests to flourish in a relatively confined area.
Explanation:
While modern civilizations extend to every continent except Antarctica, most scholars place the earliest cradles of civilizations—in other words, where civilizations first emerged—in modern-day Iraq, Egypt, India, China, Peru and Mexico, beginning between approximately 4000 and 3000 B.C.
Answer:
D. flat-topped trees scattered throughout.
Explanation:
Grasslands are vast area of land covered in grass. In such environment, grasses are favor to grow but trees shrubs and other tall plants are not favored to grow.
Savannas are also vast lands that supports the growth of grasses and trees scattered across the land.
So, in savanna there are trees scattered throughout the land and grasses, but grasslands only have grasses growing in the vast area.
