Answer:

<h2> Parenchyma simple tissues: </h2>

Cells of parenchyma tissues live. They are oval, elongated and loosely packed with large inter-cellular space, forming basic packing of tissue and found throughout the plant body. Functions of parenchyma: They provide mechanical support to the plant body. They store food and nutrients in vacuoles.

<h2>Collenchyma simple Tissues: </h2>

Cells of collenchyma are live. They are oval and elongated and tighily packed with no inter-cellular spaces. They epidermis in leaves and stem. Functions of collenchymas tissues: They provides mechanical support to plant. They also provide flexibility to plants so that they can bend without breaking.

scoundrel [369]

Answer:

Stamen/Pistil

Explanation:

Flowering plants also called Angiosperms are a group of plants characterized by the possession of flowers used for sexual reproduction. The flowers contains the male part and female part. The male part of a flower is collectively called STAMEN while the female part is collectively called PISTIL or STYLE.

The STAMEN is responsible for the production of the male reproductive structure called POLLEN while the PISTIL is responsible for the production of female reproductive structure called OVARY. During reproduction, pollen (containing male gametes, sperm) from the STAMEN are transferred to the stigma (receptive part) of the STYLE in a process called POLLINATION.

Black coffee has a pH around 5; hand soap has a pH of 10. How many times more acidic is coffee relative

Anon25 [30]

Answer:

$\boxed {\boxed {\sf 10^5 \ or \ 100,000 \ times \ more \ acidic}}$

Explanation:

The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.

This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.

So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:

$10^ {difference \ in \ pH}$

The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.

$10^5=100,000$

Coffee is 10⁵ or 100,000 times more acidic than hand soap.
