One of the roles of ecological succession is to allow species with different adaptations to interact. Ecological succession occu

KIM [24]

Answer:

D overlap for a variety of species.

Explanation:

During ecological succession, a sequence of changes occurs in a community at a temporal and spatial level. Local colonizations and extinctions occur while ecosystems evolve at a more complex level.

Ecological succession occurs in <u>stages</u>. The first stages are represented by communities of simple trophic levels and few species. With time, as the communities go through different stages, they transform into more complex ecosystems, that are much richer in diversity, and showing more interaction among the different species that compose it. The final stage is known as the climax and represents a mature and stable system.

While the community is going through these changes, many species get extinct while many others get to emerge and survive. It occurs overlapping of different taxonomic groups that interact with each other competing or beneficiating other groups.

You are studying a cloned line of neuronal cells that grow in culture and form synapses with a cloned line of muscle cells. Thes

murzikaleks [220]

Answer:

Explanation:

TransA can be found in the plasma membrane, while TransB is found in the cytoplasm, according to the immunofluorescence localization test analysis. There are two main varieties of serotonin transporters in the neural system when it comes to serotonin signaling.

An intracellular transporter that carries and delivers serotonin throughout synaptic vesicles.
A transmembrane transporter that prevents hyperactivity overstimulation by re-uptaking serotonin from the synapse.

Therefore, suppose we compare this signaling pathway model to the analyzed experimental test. We can vividly acknowledge that TransA acts as a serotonin reuptake transporter since it is present in the plasma membrane of nerve cells and TransB is a serotonin vesicle transporter that is present and located in the cytoplasm. As a result, the majority of TransB is speculated to be present in synaptic vesicle membranes.

Unlike life at the top of a body of water, life at the bottom of the body of water

Nikitich [7]

At the top of the body of a water, there is a lot of light from the sun, which also means a lot of solar energy. This allows for a fruitful photosynthesis.

In contrast, at the bottom of the water, there isn't as much, or sometimes any, sun light. Because of this the organisms at the bottom of the body of water
<span>D. must rely on other means than photosynthesis </span>

In watermelons, bitter fruit (B) is dominant over sweet fruit (b), and yellow spots (S) are dominant over no spots (s). The gene

NikAS [45]

Answer:

A) 9:3:3:1

B) All bitter fruit, yellow spotted offsprings

C) Phenotypes are bitter yellow spotted (4), bitter no spot (4), sweet yellow spot (4), and sweet no spot (4). 1:1:1:1

Explanation:

This is a typical dihybrid cross involving two genes, one coding for fruit taste and the other for spot color. The allele for bitter taste (B) and yellow spot (S) is dominant over the allele for sweet taste (b) and no spot (s) respectively.

Hence, a heterozygous F1 resulting from a cross between an homozygous dominant (bitter fruit, yellow spot) and homozygous recessive (sweet fruit, no spot) will have a BbSs genotype. The heterozygous F1 offsprings are self-crossed and produce gametes BS, Bs, bS, bs. (See punnet square). The F2 offsprings will have the following phenotypes: Bitter fruit, yellow spot (9)

Bitter fruit, no spot (3)

Sweet fruit, yellow spot (3)

Sweet fruit, no spot (1)

Back cross between a F1 offspring (BbSs) and homozygous dominant parent (BBSS) will produce all bitter fruit, yellow spot offsprings (see attached image). BBSS (4), BBSs (4), BbSS (4), and BbSs (4) are the offsprings' genotypes.

For the back cross between a F1 offspring (BbSs) and a homozygous recessive (bbss) parent, the Phenotypes with their proportions are as follows:

Bitter fruit, yellow spot (BbSs, 4)

Bitter fruit, no spot (Bbss, 4)

Sweet fruit, yellow spot (bbSs, 4)

Sweet fruit, no spot (bbss, 4).
