Answer: Oxygen
Explanation: Photosynthesis is a process by which plants use carbon dioxide, water and sunlight to produce glucose and oxygen.
Photosynthetic reactions are divided into two phases: 1). light dependent reactions and 2). light independent reactions.
1) In light dependent reactions, chlorophyll and other light absorbing pigments absorb light energy and conserve it as ATP and NADPH with the simultaneous liberation of oxygen. This reaction occurs only when plants are illuminated. In light reactions, light energy is used to split water molecules into hydrogen ions and oxygen, the hydrogen ions produced are transferred to NADP+ to form NADPH, ATP is also produced in light dependent reactions.
2) In light independent reactions, ATP and NADPH produced in the light dependent reactions are used to drive the light independent reactions in which ATP and NADPH are used to reduce CO2 to form trioses, starch, sucrose and other products derived from them.
The answer to this question would be: Brain Natriuretic Peptide(BNP) and or Atrial Natriuretic Peptide(ANP)
Both BNP and ANP can be found in heart tissue. But BNP is more frequently used because its level is higher, thus the laboratory result could be better. Both BNP and ANP has diuretic, natriuretic and antihypertensive effect that can counter the fluid overload in congestive heart failure. That is why they are secreted when the cells are stretched.
Answer:
Predator prey
Explanation:
Animals that feed on other animals are called predators and the animals they eat are called prey. All predators have specific interactions with their prey as they are locked in an evolutionary "arms race". The prey will try to develop novel traits to survive as the predators will try to adapt to these. This is not a conscious process, but rather an evolutionary one, where prey individuals that have a survival advantage will survive and thus reproduce more.
The second image illustrates a predator-prey cycle where an increase in the prey numbers will lead to an increase in the predator numbers. This in turn will lead to a decrease in the prey number which in turn will also lead to a decrease in the predator's numbers.
The third image is a trophic or ecological pyramid in which X are the primary producers (ex. plants), Y are the animals that feed on these (prey) and Z are the predators that feed on Y. In general, top predators are not hunted and eaten by other species which is why they are at the top of the pyramid.
Answer:
Celestial ecliptic
Explanation:
In space seience , the ecliptic is really the conformance that represents the Sun's visible movement from around stars and planets over the span of a year; from some other perspective, it is the reflection on the celestial equator of Earth's orbit around the Sun. The constellation stars and planets are distributed around the ecliptic.
