What can lead to the formation of multicellular embryo in venter?
Options:
- (A) Something that makes plants green
- (B) Something made from fermented ricce
- (C) A compound that donates proton
- (D) By wind and rain
- (E) reproduction
- (F) Fertilization of gametes
- (G) metabolic reaction
- (H) heat produced
--
Let's think first: Gametes then unite in fertilization and form a diploid zygote. Diploid zygote forms multicellular embryo in venter. Fertilization of gametes can lead to the formation of multicellular embryo in venter.... So the answer is [(F)]

- (A) outside the nucleus
- (B) Most plants
- (C) solid, liquid, gas
- (D) allow growth
- (E) Veins and arteries.
- (F) Earth orbiting the Sun
- (G) Chlorophyll
- (H) the body's largest organ
--
Let's think first: Ribosomes are structures in the cytoplasm where proteins are made. Outside the nucleus is cytoplasm. Ribosomes are structures outside the nucleus where proteins are made.... So the answer is [(A)]

Options:
- (A) alive
- (B) infected
- (C) green
- (D) animals
- (E) growing
- (F) viruses

- (B) ice
- (C) porous
- (D) CO 2
- (E) complex
- (F) colonies
- (G) wetland
- (H) water
--
Let's think first: Corals form large colonies in shallow tropical water. Corals Corals are in the polyp stage. Something in the polyp stage can form large colonies in shallow tropical water.... So the answer is [(H)]

- (A) Energy
- (B) Chemicals
- (C) trees
- (D) potatoes
- (E) Acids
- (F) allow growth
- (G) store
- (H) Proteins
--
Let's think first: All animals are heterotrophs. Proteins are an essential nutrient for heterotrophs . Proteins are an essential nutrient for animals.... So the answer is [(H)]
