Horses sleep while standing, unless it is necessary for them to get REM sleep. The amount of REM sleep needed is not much, so they will spend most of their time when sleeping, standing.

The energy acquired in photosynthesis is used to make glucose. Where is the glucose made in plants?
klio [65]

Explanation:

<u>in the stroma</u>

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

  • water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain.
  • This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
  • Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules in the stroma. These store energy in their bonds, which can be released in respiration in the mitochondria.

PLEASE HELPP!! match the word with the definition
alexira [117]

Answer:

A. Miosis

B. DNA molecule

C. Body cells

D. phenotype

E. Recessive traits

F. genotype

G. Punnet square

H. nondisjunction

I. mitosis

J. sex cells

Explanation:

In meiosis cell division, a parent cell divides into four daughter cells whereas in mitosis, one cell divides into two daughter cells. If change occur in DNA molecules, mutation occurs. Phenotype refers to physical characteristics of an organism whereas genotype indicates genetic characteristics. Recessive traits only appears when the organisms have same traits or allele. Somatic cells is known as body cells whereas gametes is known as sex cells.

If the outside temperature decreases by 20 degrees Celsius, what will happen to a reptile’s body temperature?
oksian1 [2.3K]

The reptile's body temperature rises when the external temperature rises. When the temperature drops, so does his body temperature. If a reptile feels cold because the external temperatures have made his blood cold, he'll lie in the sun to warm up. However, if the external temperature is too high, he scurries under a rock, dives in a pool or finds some kind of shade where he can cool down. Reptiles and other animals with ectothermic systems are vulnerable to extreme changes in temperature because they can't control their temperatures internally. They can control their body temperatures only by moving to an environment with a suitable ambient temperature.
