The vascular bundle in the shape of a single central cylinder in a root is called the Stele.
- Vascular bundles provide the following purposes: 1. Xylem: It is essential for delivering water-related elements to various areas of the plant. 2. Phloem: This tissue is in charge of delivering nutrients and food to the plant. 3. Cambium: By producing new xylem and phloem, it contributes to secondary growth in plants.
- A group of fundamental tissues found in the stem of a plant that includes cambium, xylem, and phloem. The procambium of the developing stem is where the vascular bundles grow. In the monocotyledons, vascular bundles are scattered throughout the stem in intricate configurations.
- The major vascular system of the plant axis and its accompanying ground tissues make up the plant stele.

Answer: I would say The hypothesis that the juice of the lemon is the only pat of lemon that is capable of removing stains from the t-shirt is because the lemon juice is acidic in nature.
1.) To test the validity of this hypothesis he should test the acidity of different parts of the lemon including the juice, pulp and skin of lemon.
2.) He should also compare the lemon juice with other juices to know weather other juices are also helpful in removing stains from the t-shirt.

Answer:
The correct answer is - Histones are positively charged.
Explanation:
Histone is an octamer that is made up of four proteins and each protein has 2 copies. These proteins are H2A, H2B, H3, and H4. Histone proteins are mainly made up of positively charged amino acids like arginine and lysine which gives histone proteins an overall positive charge.
This positive charge of histone plays important role in the binding of DNA around it because phosphate group present in the DNA makes DNA negatively charged molecules that are attracted by positively charged histone protein by electrostatic interaction.
This interaction results in the wrapping of DNA around the histone proteins and then compaction of DNA into chromatin. Therefore the right answer is- histones are positively charged.
Oxygen, neccessary for cellular respiration, is the answer. As oxygen becomes scarce, your cells begin to aerobically produce very little ATP, in effect fermenting and producing lactic acid.
