Matter is neither created or destroyed during photosynthesis. With regards to the law of conservation of matter, the mass of the items framed is equivalent to the mass of the reactant.

Neither. photosynthesis demonstrates the law of conservation of matter which states that atoms cannot be created not destroyed; the matter atoms can only be rearranged into new molecules and ions. photosynthesis is aided by enzymes, special proteins, which can either break chemical bonds, or form bonds in molecules.

Answer:

provides food for embryo

Explanation:

The structure marked with an X in the figure below is called a stored nutrient reserve.

The seeds are basically formed by an integument (outer part, a stored reserve and the embryo (it is in the center of the seed), the embryo is the main creator of a new plant, for that, it needs a high load of nutrients that is provided by the nutrient reserve. In addition, the stored nutrient reserve protects the embryo from external factors such as solar radiation and freezing.

Rank the following in order from most general to most specific: 1. gametic isolation 2. reproductive isolating mechanism 3. sper

mihalych1998 [28]

<h2>Reproductive Method </h2>

Explanation:

The rank in order from the most specific which is following .

(1) Reproductive isolating mechanism

(2) Sperm-egg incompatibility in sea urchins

(3) Gametic isolation 

(4)Prezygotic isolating mechanism

(1) Reproductive isolating mechanism- The components of regenerative confinement are an assortment of transformative instruments, practices and physiological procedures basic for speciation. They keep individuals from various species from delivering posterity, or guarantee that any posterity are sterile.

(2) Sperm-egg contradiction in ocean urchins- Bindin is a gamete acknowledgment protein known to control species-explicit sperm-egg grip and layer combination in ocean urchins.

(3)Gametic isolation - Prezygotic hindrances keep preparation from occurring. Gametic disengagement is a sort of prezygotic hindrance where the gametes (egg and sperm) come into contact, yet no preparation happens. Gametes might be not able to remember each other in various species

(4) Prezygotic isolating mechanism- while postzygotic segregation forestalls the arrangement of rich posterity. Prezygotic systems incorporate environment segregation, mating seasons, "mechanical" disconnection, gamete detachment and conduct seclusion.

Describe the idea of excited electrons:

natta225 [31]

Excited electrons are those which temporarily occupy a state higher than their ground state

The electron is excited if it is given extra energy, such as when a photon, or packet of light, absorbs it or if it collides with an atom.

Why the bass and crayfish benefit from an increased level of phosphate, initially, but then die off

omeli [17]

Answer:

Increased levels of phosphate are beneficial to phytoplankton and aquatic plants. In the short-run, this means increased micronutrients for herbivorous and omnivorous fish.

The phosphate, however, reacts with the water to reduce the oxygen levels obtainable in the water. Without oxygen, the fishes die off.

It is not unusual to find that with increased phosphate in water, healthy fishes begin to die off without any other plausible explanation.

The solution is to clean the water or treat it with solutions that impact positively whilst reducing the phosphate levels.

Cheers!
