Vertebrata
Vertebrata is a group that contains various organisms which possess vertebrae (backbones). Animals that belong to the group are called vertebrates, and they include mammals, birds, fish, amphibians, and reptiles. The backbones in the animals extends from the head to the tail, and it encloses and protects the main nerve cord. The body of vertebrates is divided into trunk, and tail regions. They also possess a unique tube shaped brain, a distinct head, and three pairs of sense organs.
Answer:
Explanation:
pollen grain sticks to the stigma, where the pollen build up a pollen tube to the ovule, after fertilization the ovary then builds up to develop into a fruit, depending of the the type of flower the fruit can be determined

There is no answer to that.
Explanation:
- Chlorophyll is located in the chloroplast, and it is a crucial component in green plants for photosynthesis.
- Cells walls are present in plant cells only.
- Large central vacuoles are part of plant cells, too.
None of the options are correct.
Answer:
In the light-independent reactions, the plant starts with carbon dioxide and ends up with glyceraldehyde-3-phosphate (G3P). It uses ATP and NADPH from the light-dependent reactions as energy sources
Explanation:
<em>Step 1</em>: CO₂ adds to ribulose biphosphate (RBP) to form a six-carbon sugar that immediately decomposes into two molecules of 3-phosphopglycerate (3-PGA).
CO₂ + RBP ⟶ 2 3-PGA
<em>Step 2</em>. A phosphate group adds to the 3-PGA to form 1,3-biphosphoglycerate (1,3-BPG).
3-PGA + ATP ⟶ 1,3-BPG + ADP
<em>Step 3</em>. NADPH reduces the 1,3-BPG to G3P
1,3-BPG + NADPH ⟶ G3P + NADP⁺
Most of the G3P is regenerated into RBP, but some leaves the cycle to become glucose.
