Answer:

Hi Tadashi Here! 

Explanation:

Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.

When a pigment molecule in a light-harvesting complex absorbs a photon of light, what happens to its excited-state electron?.

MA_775_DIABLO [31]

When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.

It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll.
An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules.
An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.
Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.

According to the phylogenetic tree, which domains are more genetically related?

quester [9]

Answer: The correct answer is- Archaea and Eukarya.

As per the information about the (phylogenetic tree) given in the question,

the last branch of the phylogenetic tree begins with the line of Eukarya and then holds the species of the Archaea division, which includes those prokaryotic organisms that live in extremely harsh environmental conditions ( such as Methanobacterium, and extreme halophiles).

As this last branch holds species of two domains ( from 3 domain system of classification that includes Bacteria, Archaea, and Eukarya) , which are Archaea and Eukarya as it begins with Eukarya and later on holds the species of Archaea.

Thus, it shows that Archaea and Eukarya are more genetically related.

Plants and animals that lack color are commonly called albinos. In corn plants, green (G) is dominant to albino (g). A student

Fittoniya [83]

(B) 25% GG, 50% Gg, and 25% gg

Explanation:

Given:

Green is dominant and is coded by G

Albino is recessive and is coded by g

Two corn plants that are heterozygous for color are crossed.

The heterozygous condition of the plant would be Gg.

The cross is shown in the table attached.

According to the punnett square drawn,

The genotypic ratio is 1 : 2 : 1 (GG : Gg : gg)

= 25% GG , 50% Gg , 25% gg

Phenotypic ratio = 3 : 1 ( green : albino)

= 75% green, 25% albino
