What affects the likelihood that an allele will reach fixation in a population that has undergone a bottleneck?

1 answer:

<span>the large population becomes smaller. also, bottleneck is when a large population quickly shrinks. the effects of genetic drift becomes much stronger. e.g: seals alleles can be lost during bottleneck and the number of alleles left can shift dramatically in just a few generations.</span>

What is true about elements and compounds elements contain two or more compounds conpounds contain two or more elements compound

statuscvo [17]

Answer:

Taking into account the concepts presented in chemistry with respect to elements and compounds, it is possible to affirm that the compounds are formed by two or more elements.

Explanation:

Two or more chemical elements have the ability to bind -by forming bonds- to obtain a compound. This occurs randomly in nature.

The bonds between the elements that form a compound must be stable enough to ensure the stability of the molecule. A chemical compound can only be separated into the elements that form it by chemical processes.

The bonds types that form compounds can be:

<em>Ionic bond.</em>
<em>Covalent bond.</em>
<em>Coordinated covalent bond.</em>
<em>Metallic bond.</em>

It is necessary to mention that chemical elements are called atoms, and the bonds between them are molecules. The physical and chemical properties of a compound will be different from the properties of the elements that form it.

What are the distinguishing characteristics of invertebrates that differ from vertebrates?

vesna_86 [32]

<h3>{Differences in Physical Characteristics}</h3>

Vertebrates have a skeletal structure with a spinal column or backbone.Invertebrates have no backbone, while vertebrates have a well-developed internal skeleton of cartilage and bone and a highly developed brain that is enclosed by a skull.

Explanation:

<h3>{Invertebrates}</h3>

•Invertebrates do not possess a backbone not an internal skeleton.

•Invertebrates have an exoskeleton.

•Body size varies but most are generally smaller than vertebrates. However, some invertebrates grow to gigantic proportions – such as the colossal squid (46 feet in length).

<h3>{Vertebrates}</h3>

•Vertebrates possess a backbone and an internal skeleton.

•Vertebrates do not possess an exoskeleton.

•Generally, vertebrates are comparatively larger than invertebrates
