Answer:

Tissue level of organization

Explanation:

The various levels of the organization of life are as follows:

Cells: a cell is the basic unit of ife

Tissues; A tissue is a group of cells with a common origin. performing similar functions.

Organ: an organ is a group of tissues with varied or similar function that work together to perform a specific function.

System: a system is a group of different organs that work together in the body to perform a specific function.

Since, the leaf is an organ in the plant that performs the function of photosynthesis, the group of dermal cells found on the leaf are in the tissue level of organization, they perform the function of protection for the leaf.

The process which has taken place is called CRYSTALLIZATION.
Generally, crystallization is the process by which solid crystals are precipitated from solution. Crystallization can also occur when a crystal melt or when a crystal get deposited directly from a gas, although these cases are rarer compare to crystals forming from solutions.

This shielding is a maximum for UV light having a wavelength of 295nanometers. What is the frequency in hertz of this particular

LUCKY_DIMON [66]

Answer:

$\large \boxed{\text{1.016 $\times 10^{15}$ Hz}}$

Explanation:

The formula relating the frequency (f) and wavelength (λ) is

fλ = c

1. Convert nanometres to metres

295 nm = 295 × 10⁻⁹ m

2. Calculate the frequency

$\begin{array}{rcl}f \times 295 \times 10^{-9} \text{ m}& =& 2.998 \times 10^{8} \text{ m$\cdot$s$^{-1}$}\\\\f & = & \dfrac{2.998 \times 10^{8} \text{ m$\cdot$s$^{-1}$}}{295 \times 10^{-9}\text{ m}}\\\\& = &1.016 \times 10^{15}\text{ s}^{-1}\\& = &\large \boxed{\textbf{1.016 $\mathbf{\times 10^{15}}$ Hz}}\end{array}$

Metal cations are atoms that have a positive charge. What type of bond is a metal cation likely to form? A. covalent bond B. dou

Lunna [17]

Answer:

D. ionic bond

Explanation:

Due to electron deficiency in a metal cation, they cannot form a covalent bond beacuse it means to share electrons. By contrast metal cation seek for electrons. In an ionic bond, one atom give electrons, while another atom recevie electron. Because of that, this is the better option to metal cations.

Spell out the full name of the compound.

Natalka [10]

Explanation:

Step one look for the longest chain of carbon atoms

Longest chain is 7 C atoms

Step 2 look for double bonds or others functional groups

it is present in 3rd carbon

Therefore IUPAC name is 3-heptene

From point of stereochemistry it can also be written as trans-3-heptene as the hydrogens are placed in opposite side of the C=C bond.

Hope this helps...

Which two functional groups react to form an easter linkage?

7nadin3 [17]

Answer: You know that monomers that are joined by condensation polymerization have two functional groups. You also know (from Part 6) that a carboxylic acid and an amine can form an amide linkage, jand a carboxylic acid and an alcohol can form an ester linkage.
