Allushta [10]

Answer:

Transcription factor binding would be reduced or eliminated, and transcription of the gene would decrease dramatically.

Explanation:

Mutation means the changing of the structure of the gene that results in the variant form which may be transmitted to the subsequent generations.  They are caused by the altering the the single base units in the DNA of the species.

In both eukaryotic as well as prokaryotic, the mutation can affect the diversity in the future generation of the cells.

The eukaryotic mutation of the gene affects the transcription of the gene as the transcription factor binding will be lowered or will be eliminated and the transcription of this gene will decrease.

How does the photosynthetic reaction center differ from the chorophyll molecules in the antenna complex?
o-na [289]

Answer:

Photosynthetic reaction center differ from the chlorophyll molecules in the antenna complex by the presence  and absence of core pigment and accessory pigment.

Explanation:

Photosynthetic reaction center contain core pigment known as chlorophyll  A which can aborb wavelength of sunlight not more than 700 nm in case of Photosystem 1 and the core chlorophyll pigment of Photosystem 2 absorb light having wavelength of 680nm or less than that.

                           Antenna complex or light harvesting complex  such as chlorophyll b ,Carotenoid,Xanthophyll absorb light energy from sunlight and transfer that light energy to photosynthetic reaction center by resonance energy transfer so that the photosynthetic reaction center uses the same(light energy) in form of chemical energy to out the further reactions of photosynthesis.

pentagon [3]

The correct answer is option (a). Parent material

The soil horizon refers to distinct layers of the soils, which are parallel to one another, but have a different composition from the layer present above and below to it.

The soil horizon can be divided into four different layers. First one is organic layer, which is the topmost layer, below this layer second layer of topsoil is present. Below top soil, subsoil is present. Below subsoil, the bottom most horizon parent material is present.
