Nuthatches and brown creepers are birds which eat insects that hide in the furrows of bark in hardwood trees. The creeper search
jeka94

Answer:

This are our options to complete the question

-bottom-up and top-down hypotheses

-competitive exclusion

-keystone species

-resource partitioning

-character displacement

The CORRECT ANSWER IS resource partitioning.

Explanation:

Resource partitioning is the division of certain limited resources by species to eliminate competition in an ecological niche in order to allow easy coexisting with one another

The creeper searches for insects by hunting from the bottom of the tree trunk to the top, whereas the nuthatch searches from the top of the trunk down to eliminate competition and allow for peaceful coexisting between them

Alternation of generations in plants permits(1 point) neither mitosis nor meiosis. only meiosis. both mitosis and meiosis. only
nekit [7.7K]

Answer:

Alternation of generations in plants permits both mitosis and meiosis but at different stages.

The zygote will undergo many rounds of <u>mitosis</u> and give rise to a diploid multicellular plant called a sporophyte. Specialized cells of the sporophyte will undergo <u>meiosis</u> and produce haploid spores.

Hope it helps,

I'm not so sure.

What is the role of ATP synthase in photosynthesis?
german

The role of ATP synthase in photosynthesis is to transports a proton down the gradient and uses the energy to complete the phosphorylation of ADP to ATP.

Further Explanation:

Photosynthesis starts with the absorption of light or solar energy by the plant pigments called chlorophyll. The activated chlorophyll molecule helps in the electron transfer from one acceptor to another forming a chain.

The first phase of photosynthesis the light-dependent reaction in which the absorbed light is utilized to produce molecules carrying energy that is used in the second phase to form carbohydrates by reducing carbon dioxide. The first phase occurs in the grana region of the chloroplast and involves the transport of electrons through photosystem II (PS II) followed by photosystem I (PS I). The energy gained by the chlorophyll molecule is transferred to PS II in the form of electrons. These electrons are passed on further through a series of electron transporter or carrier from PS II to PS I. In photosystem I, finally, the electron is gained by NADP+ to form NADPH.

The ATP synthesis is produced by the use of proton motive force this reaction is catalyzed by ATP synthase. This a multiprotein synthase is also well-known as F0 F1 complex .The ATP molecule is synthesized when proton flow back from the inner membrane down the electrochemical proton gradient . ATP synthase has two components F1 ATPase and F0 which is embedded in the inner membrane and contain alpha, beta and C unit.

As the electrons travel along the electron transport chain, energy is released which helps in the pumping of protons (ions) into the lumen from the stroma through the thylakoid membrane. A proton gradient is developed which allows the movement of protons back to the stroma which in turn results in the formation of ATP through membrane-bound ATP synthase

The second phase of the photosynthesis is the dark reaction or the light-independent reaction happens in the stroma and utilizes the products formed during the light-dependent phase.
