Answer:Polaris is directly overhead (i.e. at zenith) at the North Pole and at the horizon for an observer at the equator. The rule of thumb for the altitude of Polaris is that the altitude of Polaris equals your latitude on Earth.

Explain the Three position of Meristematic tissues​
son4ous [18]
<h2>Answer:</h2>

There are three types of meristems on the basis of position, i.e

  1. Apical meristem.
  2. Lateral meristem.
  3. Intercalary meristem.
<h2>Explanation:</h2>

A meristem is the tissue present in  most plants containing undifferentiated cells, found in zones of the plant where growth can take place. Generally differentiated cells(the cells other than meristems) do not divide and produce of a different type of cells.

Meristems are classified on the basis of their location in the plant:

  1. Apical meristem - these are the meristems located at root and shoot tips of the plant.
  2. Lateral meristem - these are the meristems located in the vascular and cork cambia in plants.
  3. Intercalary meristems - these are the meristems located at internodes, or stem regions between the places at which leaves attach, and leaf bases.

Result: There are 3 types of meristems.

Can someone write the first paragraph
Katena32 [7]

Hii!!

The purpose of mitosis is to create two new perfectly identical cells when either there is a need to replace old or damaged cells and to reproduce asexually by making new cells. Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring.

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres

2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)

3) Anaphase: sister chromatids are pulled to opposite poles of the cell

4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin

● The order of the stages of mitosis can be remembered using the mnemonic PMAT.

Hope this helps!! if it has pls mark me as the brainliest Xd :D
