Answer:
1.abiotic- air and biotic-birds
2.producing delicious and good fruits for animals protect and help them to spread. delicious food attract animals like birds and other animals who are feed on them. when they eat the fruits and the seeds pass by unharmed. these way the seed dispersal occur of a plants.
Answer:
See the answer below
Explanation:
Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways
- <em>Negative feedbacks</em>
- <em>Positive feedbacks</em>
Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat
Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.
Answer:
16. mitochondria
17. lysosomes
18. smooth Endoplasmic Reticulum
19. golgi body
20. golgi complex
Explanation:
16. Mitochondria are double membrane-bound cell organelles responsible for the supply and storage of energy for the cell
17. While cells mainly use lysosomes to dispose of trash. Sometimes they simply hang onto their trash, performing the cellular equivalent of sweeping it under the rug
18. Are the storage organelle, associated with the production of lipids, steroids, and also responsible for detoxifying the cell.
19. The Golgi body is the sorting organelle of the cell. Proteins are transported from the rough endoplasmic reticulum (RER) to the Golgi.
20. is responsible for sorting and correctly shipping the proteins produce the ER. Just like our postal packages, which should have a correct shipping address, the proteins produced in the ER should be correctly sent to their respective address. It is a very important step in protein synthesis.

If I am wrong, please tell me, I enjoy learning from my mistakes:)
Answer:
The strong hydrogen bonds in water made water stable and difficult to breakdown into constituent oxygen and hydrogen atoms. at a temprature less than 100 degree..
Oxygen is a strong electronegative atom than the two hydrogen atoms it is attached to in water. It pulls more electrons to itself than the hydrogen atoms.. This strengthened hydrogen bonds in water .
Consequently, it will be difficult for the needed oxygen atoms to simply diffuse into the alveoli to reach the blood,Compare to its molecular form where its atoms awere held by relatively week covalent bonds.
Besides the porosity of the thin alveolar endothelial walls of 0.2 micrometer is too small for the larger water molecules to pass through.
