Hydrogen ions are important in the light-dependent reactions of photosynthesis because they produce a

Mnenie [13.5K]

Answer:

a. the production of ATP

Explanation:

Photosynthesis is type of biosynthesis that produces glucose from the reactants sunlight, carbon dioxide and water. It happens in two phases of the chloroplast, the light-dependent and light-independent reactions. In a light reaction that stimulates photosystems, pigments such as chlorophyll absorb light energy at specific wavelengths. Here,

Light energy stimulates photosystem complexes formed from chlorophyll. Photosystem II then absorbs and transfers light to a reaction core.
Water undergoes hydrolysis or splitting to yield an electron, a proton (H+) and oxygen.
energy is passed along the electron transport chain, where it forms builds up H+ and an electrochemical gradient in the thylakoid space
These protons pass through the ATPase enzyme embedded within the membrane, into the stroma, generating ATP from ADP.
NADPH is generated from NADP+

Why is it important for ectoparasites to stay undetected by their host?

melomori [17]

Ectoparasites cause diseases in humans and animals, so to know the format of detecting it we need to know that ......

<h3>Ectoparasite</h3><h3 />

Parasitism is defined as an interaction where a parasitic organism obtains resources through one or several host individuals, causing damage and reducing its fitness. The endoparasite is a type of parasite that lives inside the host's body (from the Greek endos, inside), while the ectoparasite is one that lives on the external surface of its host (from the Greek ectos, outside). Thus, the ectoparasite does not need to lodge inside the host organism to feed, presenting a partial metabolic dependence. Some examples of ectoparasites are:

Lice
Ticks
and Fleas.

<h3>Strategies of ectoparasites</h3>

Each parasite has particular strategies and adaptations used to extract nutrients from their hosts. In ectoparasites these adaptations can often be seen as changes in the oral apparatus, allowing them to penetrate the skin surface and feed on the host's nutrients. Scabies is a skin disease caused by the ectoparasite Sarcoptes scabiei. In order to obtain nutrients for its survival, the parasitic organism burrows into the skin of the host, unlike ectoparasites such as the louse, which pierce the surface and only insert its mouthparts to extract food.

With this information we can say that the ectoparasites adapt to the host so that it is not noticed and for a better absorption of nutrients from the host, they remain undetectable not to be removed, so that they are not disconnected from their food source as they are in the vast majority visible to the eye.

If an organism has a genotype of DdGg, which could be one of the gametes produced?

fgiga [73]

I believe that the best answer would be Dg. Based on the law of independent assortment, during meiosis, any allele from one trait can end up in the same gamete with any allele from another trait, Such that in this case the individual with genotype DdGg can produce DG, Dg, dG, or dg gametes, only applies to genes that are not linked on the same chromosome.
