Describe the potential effects when a keystone species is removed from a community.

Vlad [161]

Answer:

Explanation:

A keystone species is the one which plays an important role in maintaining the structure of the ecosystem. On the keystone species many other species of the ecosystem are dependent upon.

The potential effects associated with the keystone species includes the following:

1. No other species will be capable of filling the same ecological niche. Hence, the dependent organisms will suffer and the ecosystem will change drastically.

2. The ecosystem will be populated by the invasive species which will affects the population of native species.

If there is complete linkage with genes Ss (for smooth or wrinkled seeds) and Gg (for green or yellow seeds), what phenotypes wo

KonstantinChe [14]

Answer:

Smooth and green seeds

Smooth and yellow seeds

Wrinkled and green seeds

Wrinkled and yellow seeds

Explanation:

This is a typical dihybrid cross involving two linked genes; one gene coding for seed texture and the other for seed colour. The allele for Smooth seed (S) is dominant over the allele for Wrinkled seed (s) in the first gene while the allele for green seed (G) is dominant over the allele for yellow seed (g) in the second gene.

The cross is between a heterozygous smooth, green plant and a homozygous recessive wrinkled, yellow plant

According to the law of independent assortment, each parent will undergo meiosis to produce the following gamtes with genotypes:

SsGg: SG, Sg, sG, sg

ssgg: sg, sg, sg, sg

Using a punnet square to perform a cross between these gametes ( check attached image), a total of 16 offsprings with four different phenotypes will be expected. The phenotypes are as follows:

SsGg: Smooth and green offsprings (4)

Ssgg: Smooth and yellow offsprings (4)

ssGg: Wrinkled and green offsprings (4)

ssgg: wrinkled and yellow offsprings (4)

How are signals sent from one neuron to another by jumping across a tiny space or?

Irina-Kira [14]

<span>Transmitted via neurotransmitters. There is a gap between two neurons. This place where the axon meets with dendrite is callde synapse. Neurotransmitters which are chemicals help transmit the signals from axon to dentrite. Calcium ions play major role in this process.</span>
