Explanation:
during the embryonic stage the baby grows its organs
Nervous system. This is one of the first things that develop. It includes the formation of the baby’s brain, spinal cord, and nerves.
Heart. An S-shaped tube forms on the front of the embryo. This will become the baby’s heart. At first the heart does not beat, but soon it starts beating and pumping an early form of blood.
Face. The baby’s facial features begin to take shape. The eyes and ears form. The eyes move forward on the face, and eyelids form. Pieces of tissue grow and join together to create the forehead, nose, cheeks, lips, and jaw. The nasal passages, mouth, and tooth buds form the baby’s first teeth. A tongue with taste buds also forms.
Arms and legs. At first, the baby’s arms and legs begin as little buds that sprout from the embryo’s sides. As they grow, the arms look like paddles and the legs look like flippers. A ridge appears on the end of each one. They eventually become the baby’s fingers and toes.
Sexual organs. Cells form to become the baby’s eggs or sperm. The baby’s private parts (girl/boy) is visible at the end of the embryonic period.
Muscles and movement. Muscles develop and the embryo begins to move. At first it’s only twitching and reacting to touch. Once the nerves and muscles start working together, the baby can start moving on purpose.
Answer:
b) there are 56 deer in 1000 acres of area.
Explanation:
If a person has 1000 aces of land and a local wildlife biologist tell him that on every 18 acres only one deer is present so in 1000 acres there are 56 deer are present.
calculation;
1 deer ------ 18 acres
x --------- 1000 acres
by cross multiplication, we get
18 x = 1000
both side divided by 18, we get
x = 55.5
by rounding off we get
x = 56
