Summarize the order of events from egg and sperm to embryo?
(ill give brainliest)
Sperm fertilizes the egg, the egg turns into a zygote, the zygote then goes through the process of cell division and turns into an embryo.
• Post ejaculation, the sperm cells meet the egg, and fusion between both the cells takes place.
• The fusion results in the formation of a single cell, which comprises the genetic material from both the egg cell and the sperm cell, this is called a zygote.
• The zygote further divides into sixteen cells stage called the morula.
• Post three days after the formation of morula, formation of the embryo takes place. The embryo attaches to the wall of the mother's uterus.
Thus, egg and sperm fuse and give rise to the zygote, this zygote further undergoes several divisions and eventually results in the formation of an embryo.

How do Newton’s laws of motion explain why it is important to keep the ice smooth on a hockey rink so that players can pass a puck as quickly as possible?
Smooth ice reduces the inertia of the hockey puck.
Smooth ice increases the force used to accelerate the hockey puck.
Smooth ice reduces the unbalanced forces that would slow the hockey puck.
Smooth ice decreases the reaction force that the ice exerts on the hockey puck.
It is important to keep the ice smooth on a hockey rink because this reduces the unbalanced forces that would slow the hockey puck.
Frictional forcesFrictional forces are opposing forces to the motion of an object on a platform.
In order to be able to pass a puck as quickly as possible on a hockey rink, there should be a minimal frictional force on the ice surface on which the puck moves.
With minimal opposing forces, the puck will move as unhindered as possible and passing as fast as possible would be easy.

(Picture included) The student investigated the movement of water through plants. The plants were covered with clear plastic to capture any water released into the air. The plants received the same amount of water and sunlight.
Which conclusion is supported by these data?
- Leaves contain cells that store water for respiration.
- Leaves contain cells that control the release of water into the air.
-Leaves contain cells that absorb sunlight and water during photosynthesis.
- Leaves contain cells that stimulate growth by moving water through the plant.
Answer: C -Leaves contain cells that absorb sunlight and water during photosynthesis.
Explanation:
Leaves contain cells that absorb sunlight and water during photosynthesis. That's why after three hours the amount of water decreases as the number of leaves increases. Option (C) is correct.
What are stomata in leaves ?Water is taken up by roots from the soil and moved as a liquid by xylem to the leaves. Small holes in the leaves allow CO2 to enter the leaf for photosynthesis and water to escape as a vapor.
The rate of gas exchange is regulated by stomata, which are pores present in the epidermis of leaves, stems, and other organs. A pair of specialized parenchyma cells called guard cells surrounds the pore, controlling the size of the stomatal opening.
They are essential to photosynthesis because they allow carbon dioxide to enter the leaf and oxygen to leave. Additionally, the stomata aid in transpiration, the process of releasing water vapor through a plant's leaves.
Thus, option (C) is correct about leaves.

New seed does not germinate in spite of suitable environment Why?
Answer:
All seeds do not germinate to form new plant because some are not fulfilled with the appropriate amount of nutrients.
Explanation:
A new seed does not germinate in spite of a suitable environment due to a lack of enough nutrients in the soil, a seed may undergo the dormant stage, and too much or little water in the soil.
What is Germination?Germination may be defined as a process through which a seed grows into a seedling.
A lack of nutrients does not deliver enough energy to seed for germination. If the soil has too little water or no water, a seed remains dormant throughout, while if it has too high water, then the seed becomes susceptible to infections.
Under all the above conditions, a seed will germinate into a seedling in spite of a suitable environment.
Therefore, it is well described above.
