Respiratory System
What type of cell is found in the capillaries?
Red blood cell
This side of the heart has deoxygenated blood
Right
How many chromosomes are in the daughter cells of a cell that has 10 chromosomes in Mitosis?
10 chromosomes each
What is the stage of a developing baby called when the umbilical cord is attached?
Fetus
What is the importance of flowers to a plant?
Reproduction and Multiplication
Where does gas exchange occur?
Alveoli
This organ acts as a pump
Heart
How many chromosomes are in the daughter cells of a cell that has 10 chromosomes in Meiosis?
5 chromosomes each
What is the function of amniotic fluid?
Amniotic fluid surrounds the growing fetus in the womb and protects the fetus from injury and temperature changes.
What is germination?
The process of a seed developing into a young plant
Give THREE features of the alveoli that helps them function efficiently.
Large surface area, thin walls (one cell thick), they have tiny blood vessels called capillaries
What are TWO common disorders of the circulatory system that are related to a diet high in fats.
What term is used to describe the daughter cells produced by a cell in Mitosis and Meiosis?
Diploid and Haploid
How does the placenta supply the fetus with oxygen?
The fetus is connected by the umbilical cord to the placenta. Through the blood vessels in the umbilical cord, the fetus receives all the necessary nutrition, oxygen, and life support from the mother through the placenta.
List three environmental factors needed for seeds to germinate.
Oxygen, water and warm temperature.
What happens during breathing to expel air from the alveoli?
In exhalation, the diaphragm moves upward and the chest wall muscles relax, causing the chest cavity to get smaller and push air out of respiratory system through the nose or mouth
Why is the wall of the left ventricle thicker than the right?
The wall of the left ventricle is thicker than that of the right ventricle because the left ventricle pumps blood for all the parts and tissues of the body and hence, need thicker walls for more work that needs to be done
Name a tissue in the body where mitosis takes place.
Name a tissue in the body where meiosis takes place.
Skin cells (Mitosis)
Testes and Ovaries (Meiosis)
What are some substances that pass through the umbilical cord from the fetus to the mother?
What are two advantages a germinating seed has if the radicle grows out first before its plumule?
The radicle absorbs water and essential nutrients from the soil which helps and boosts the growth of plumule and allows the photosynthesis to occur by providing raw materials.
List one disease a person's lifestyle of smoking cigarettes affects their alveoli.
Emphysema- inflammation of the lungs
The heart is said to be a double pump, what does that mean?
The first pump carries oxygen-poor blood to your lungs, where it unloads carbon dioxide and picks up oxygen. It then delivers oxygen-rich blood back to your heart. The second pump delivers oxygen-rich blood to every part of your body.
What are two processes in living things which occur by mitosis and meiosis?
Mitosis is the main cell division process which is used to produce new body cells in all living organisms. Ex. Tissue repair and asexual reproduction.
Meiosis living processes are oogenesis and spermatogenesis.
What blood vessel in the umbilical cord transports blood towards the body of the developing baby?
Umbilical vein that carries food and oxygen from the placenta to your baby
DOUBLE POINTS.
List the function of each part of the flowering plant
Receptacle: The part of a flower stalk where the parts of the flower are attached.
Sepal: The outer parts of the flower (often green and leaf-like) that enclose a developing bud.
Petal: The parts of a flower that are often conspicuously colored.
Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther.
Anther: The part of the stamen where pollen is produced.
Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed.
Stigma: The part of the pistil where pollen germinates.
Ovary: The enlarged basal portion of the pistil where ovules are produced.
