In shorthorn cattle, when a red bull (RR) is crossed with a white cow (WW), all the offspring are roan—a spotted, red and white color. What offspring are expected from mating a roan bull and a roan cow?
Answer:
25% red
50% roan
25% white
Explanation:
When RR (red) is crossed with WW (white), it results in roan color.
RR (red) x WW (white)
RW (roan)
Two roan individuals are then mated.
RW x RW
RR RW RW WW
Offspring
1/4 RR - Red
1/2 RW - Roan
1/4 WW - White
Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.

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.

(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.
