Can someone please help me with this ap biology problem! I would really appreciate it:)
strojnjashka [21]

Answer:

D - the production of a specific mRNA will increase as a result of the binding of the hormone receptor complex to the DNA

Explanation:

We are told that the hormone binds a receptor and then enters the cell, binding to the DNA and promoting transcription of a specific gene.

Transcription is the process whereby mRNA molecules are synthesised from a DNA sequence, which are then translated into specific process. D is correct, as the gene the hormone binds to will increase in transcription, producing a specific mRNA.

A, B and C are much more general processes, not linked to the actions of a hormone on a specific gene.

The dichotomous key is an important tool to identify the species of living beings, with this tool it was possible to identify the proposed species, however, to understand this question, we need to know that.......

<h3>Dichotomous Key for Insects</h3><h3 />

This dichotomous key is a simplification and is used to find the order of most insects. But as in biology there is always someone or something to deny us, there are insects that defy this order 1.

Start by choosing between one of the two alternatives of option number 1 and go to the indicated number:

 

  1. - Obvious, membranous wings, sometimes covered with scales or fur:  - Wings absent or forewings thick and hiding membranous hindwings: 15
  2. Wings covered with small scales and proboscis-shaped mouthparts: LEPIDOPTERA
    - Wings not covered with scales, usually translucent. Mouthpiece is not a proboscis: 3
  3. - With a pair of wings: DIPTERA
    - With two pairs of wings: 4
  4. - Long, narrow wings, fringed with fur. Size 5 mm or less: THYSANOPTERA
    - Wings not narrow and fringed: 5
  5. - Abdomen with 2 or 3 long filaments. Small hindwings: EPHEMEROPTERA
    - Abdomen with short filaments or none. Full-sized hindwings: 6
  6. - Forewings clearly longer and with a larger area than the hind wings: - Four forewings as long as, or nearly as long as the hind wings and with a similar or smaller area: 10
  7. - Wings hairy, opaque, with long palps antennae as long as the body or longer: TRICHOPTERA
    - Transparent or translucent wings, hairless, palps short or absent, antennae shorter than the body: 8
  8. - Tarsus with 5 segments, usually with a wasp or bee face: HYMENOPTERA
    - Tarsus with 2 or 3 segments, without a bee or wasp face: 9
  9. - Sucking mouthpiece, nozzle starting at the back of the head. Small to large: HOMOPTERA
    - Chewing mouthpiece, without beak, length 7 mm or less: PSOCOPTERA
  10. - Head extended ventrally forming beak-shaped structure: MECOPTERA
    - Head not extended ventrally: 11
  11. - Very short antennae with thick fur and large eyes: ODONATA
    - Antennas not so short. Moderate to small eyes: 12
  12. - Hindwings wider than forewings. Cerci present: PLECOPTERA
    - Hindwings as wide or almost as wide as forewings.  

With this identification key we can taxonomically classify the 10 insects contained in the question, and with that we can discover the species we are studying.

Taxonomy is an important tool to better understand the species of living beings, their species diversity and their role in ecology.
