Answer:
Option C, Paramecium
Explanation:
Complete question
Which of these organisms contains no specialized cells?
a. Sea anemone
b. Jellyfish
c. Paramecium
d. Sponge
Solution -
Paramecium consists of only cell and hence the chance of it having specialized cells is nill. Its size is somewhere around between 50 to 300 micrometer. It belongs to kingdom Protista and is a single celled eukaryote. While on the other hand sea anemone, sponge and jelly fishes are multicellular with various special structures such as tentacles, cilia , flagella. Hence, these three must be having specialized cell.
Any infectious diseases can be prevented by vaccinations
<u>Explanation:</u>
- Vaccines defend against infectious diseases that cause severe illness and seldom death.
- It prevents disease in somebody who receives them and protects those who get into contact with unvaccinated individuals.
- Vaccines include the corresponding antigens or parts of it that cause illnesses, but the antigens in vaccines are either destroyed or incapacitated.
- When they are introduced into fatty tissue or muscle, vaccine antigens are not powerful enough to generate the symptoms and signs of the disease but are tough enough for the immune system to build antibodies against them.
Answer/Explanation:
Two unaffected parents can have affected children, that means cystic fibrosis must be a recessive trait.
The two parents must each have one copy of the cystic fibrosis allele, but are themselves unaffected. By chance, the son (shaded) inherited both of these copies and is affected. The daughter either inherited one or zero copies of the cystic fibrosis allele, as she is unaffected.
Explanation:
O2- this is produced by oxidizing water in the light reaction.
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). An increase in temperature will increase the rate of photosynthesis.
It happens in several complicated stages, photosynthesis is a rate-limited process, based on several conditions including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reducing agent.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen

Answer:
Bald eagle populations declined dramatically in the last century, attributed mostly to the accumulation of the pesticide DDT in fish, The pesticides gradually poisoned females, causing them to produce thinly-shelled eggs that broke easily, preventing the embryos from growing.
