Answer:

passive immunity

Explanation:

antibodies from the mother are passed to her unborn baby through the placenta. this type of immunity is called passive immunity because the baby has been given antibodies rather than making them itself.

<span>Actually baby Aiden will surely develop a strong secretory Iga antibodies which is passive immunity to most of the types of bacteria and viruses, ie, as a protection against infections, which inturn is a response to the baby to its immune system in the form active immunity.</span>

What happens during the initiation step of DNA transcription? A ribosome attaches to the initiation codon of a completed mRNA st
Amanda [17]

Answer:

<u>A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.</u>

Explanation:

Transcription is the process in which DNA template is used to synthesize  mRNA.

There are three steps of transcription:

  • <u>Initiation</u>

It is the process in  which a portion of DNA unwinds and RNA polymerase binds to the promotor region on the DNA.

  • <u>Elongation</u>

It is the process in which RNA polymerase moves along the DNA template and synthesizes mRNA. During this process, unwinding of double stranded DNA takes place.

  • <u>Termination</u>

As the RNA polymerase moves along the DNA template, it finally reaches a termination signal and then stops synthesizing. It is followed by the detachment of the newly formed mRNA and RNA polymerase from the DNA.

<u>QUESTION:</u>

  • <u> A ribosome attaches to the initiation codon of a completed mRNA strand.</u>

This is the incorrect answer choice as this process does not happen in the process of transcription. This event happens<u> in the process of translation in which mRNA is used to synthesize proteins or amino acids. mRNA attaches to ribosome during this process.</u>

  • <u>RNA polymerase moves along the template strand of the DNA creating an mRNA strand.</u>

This is the incorrect answer choice as this event takes place in the process of elongation.

  • <u>A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.</u>

This is the<u> correct answer choice as this event takes place in the process of initiation of transcription</u>

  • <u>The mRNA detaches from the RNA polymerase as the RNA polymerase leaves the DNA strand.</u>

This is the incorrect answer choice. This event takes place in the event of termination of transcription.

An AAaa tetraploid plant undergoes self-fertilization. At least two dominant A alleles are needed to obtain the dominant phenoty
MatroZZZ [7]

Answer:

The frequency will be  35/36

Explanation:

An AAaa tetraploid plant will only produce a gamete which will be Aa, but during a self crossing a progeny with genotype AAaa will be produced and this will happen at a frequency of 35/36 and this simply means that the progenies produced during the self crossing  will all have a dominant phenotype

What are two techniques used to restore biodiversity
Zarrin [17]

Two techniques that are used in order to restore the biodiversity are the sawing of native seeds or planting individual plants, and the reintroduction of animal species native to the ecosystem.

The restoration of the biodiversity is practically trying to get an ecosystem in its initial, pre-destruction condition, and help it function without any human assistance after certain amount of time.

All restorations of the biodiversity are hard and take time, and there's no guarantee that the outcome will be as planned and wanted. Initially, there the sawing of native seeds and planting individual plants, which is crucial as the plants are the basis of the ecosystems. After that animal species are introduced, small and large, herbivores, omnivores, and carnivores. The people initially have to assist the functioning of the ecosystem, but the idea is to make it function properly over time on its own.
