it's spring tide.
Explanation:
The smallest tidal ranges are less than 1 m (3 feet). The highest tides, called spring tides, are formed when the earth, sun and moon are lined up in a row. This happens every two weeks during a new moon or full moon. Smaller tides, called neap tides, are formed when the earth, sun and moon form a right angle.

Answer:
i think protons and neutrons
Explanation:
im not sure tho
Answer:
Atomic mass is calculated by adding the masses of protons and neutrons in a given atom of an element.
Explanation:
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
Atomic mass is (just slightly less than) the sum of the masses of protons and neutrons in a given atom of an element.
hope this helps and is correct! :)

During which phase change will two grams of water
release 668 joules of heat energy?
A. melting
B.
freezing
C.
vaporization
D. condensation
During the phase change of 2 grams water to solid-state, there has been the release of energy, and the process will be freezing. Thus option B is correct.
The release of the amount of heat by the sample has been able to change the state of the matter from the loosely bounded to the combat state.
The melting has been the process of conversion of solid-state to a liquid state. In the process, there has been the absorption of the energy for the rupture of the bond.The freezing has been the conversion of liquid state to solid-state. The process requires a little amount of energy for the conversion.The vaporization requires the absorption of energy and converts the liquid state to the vapor state.The condensation has been the process of conversion of the vapor to the gaseous state. The process releases energy in large amounts.Thus, during the phase change of 2 grams water to solid-state, there has been the release of energy, and the process will be freezing. Thus option B is correct.

What part do the stamen and the ovule play in plant reproduction?
Question 7 options:
The stamen is the female reproductive part of the plant and it produces pollen.
The stamen holds the ovule and stigma together and produces pollen for fertilization.
When the stamen receives pollen from the plant, it is able to produce seeds and fruit.
When the stamen produces pollen, the ovule receives pollen to produce seeds and fruit.
Answer:
D. When the stamen produces pollen, the ovule receives pollen to produce seeds and fruit.
Explanation:
The stamen is the male reproductive organ of a plant and the ovule is a female reproductive part of a plant. (So we can rule out the first answer choice because stamen is in male plants not female plants).
The stamen produces pollen which sticks to pollinators such as bees when they land on the male plant. (So we can rule out the third one because pollen is produced by stamen and not received).
When the pollinators travel to female plants, the pollen gets deposited into the ovule which then produces seeds and fruit. (So we can rule out the second one because pollen is transported from one plant to the other by pollinators, not by the plants themselves).
Hope this is correct and helps!

The flowering plants reproduce sexually through a process known as the pollination. When the stamen produces pollen, the ovule receives pollen to produce seeds and fruit. The correct option is D.
What is pollination?The process of transfer of pollen grains from the male anther of a flower to the female stigma is defined as the pollination. It can occur either within a flower or between the flowers of the same plant or flowers of different plants.
The male sex organ of a flower is stamen and the female part is pistil. The anther of the stamen contains pollen which consist of the male gametes. The movement of pollen to the stigma causes reproduction.
The innermost part of a flower is called the carpel. It contains ovary where eggs or ovules are located. The pollen from anther enter the ovary and fertilize an ovule in order to develop a seed.
Thus the correct option is D.
