Match the following terms and definitions. 1. an electrical nerve impulse sent by nerve fibers to the central nervous system for
vladimir1956 [14]

Answer:

1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. <u>Action potential. </u>

2. neurons that detect chemicals such as those found in food. <u>Chemoreceptors. </u>

3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. <u>Compound eyes. </u>

4. the structure that gives the response to an environmental change.<u> Effector</u>

5. neurons that detect electrical fields. <u>Electroreceptors. </u>

6. secretion of hormones into the blood stream to affect distant processes. <u>Endocrine.</u>

Explanation:  

An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.

There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.

Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.

The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.

There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.

Which of the following characteristics will most likely be helpful in identifying a butterfly using a dichotomous key?Migrates n
jeka94

Answer: Hind wings have tail extensions.

Explanation:

The dichotomous key is a tool which is used by the scientists to identify the unknown living organisms by comparing the observable characteristics of unknown with known living organisms. It stresses to identify the organisms or species by their scientific names and every species has a particular scientific name. Hind wings of butterfly is the observable characteristic which can be compared with that of other known butterfly species that also have a tail extension. This physical characteristic will help in identification of butterfly.

Michelle was curious about her mother's blood type. Michelle knew that her own blood type was o,
babymother [125]

Blood type is determined by the I gene. IAIA and IAi determines A blood type. IBIB and IBi determines B blood type. ii determines 0 blood type. <em>Michelle's mother must at least carry one recessive allele i</em>.

--------------------------------

The blood type is determined by a gene, which is triallelic.

  • IA dominant over i. The person presents A type of antigens.

  • IB dominant over i. The person presents B type of antigens.

  • IA and IB are codominant. The person presents both types of antigens, A and B.

  • i is the recessive allele. The person does not present any antigen.

⇒  H0m0zyg0us dominant individuals IAIA, or heter0zyg0us Individuals IAi, will express the A blood type.

⇒  H0m0zyg0us dominant individuals IBIB, or heter0zyg0us Individuals IBi, will express the B blood type.

⇒ Individuals with h0m0zyg0us recessive genotype, ii will express the 0 blood type.

⇒ Individuals carrying IA and IB alleles will express the AB blood type.

To solve the problem, we will use this information.

We know that

  • Michelle is blood type 0

  • Father is blood type A

  • Brother and sister are blood type A

  • Mother??

⇒ If Michelle is blood type 0, then her genotype is ii. She must have received one recessive allele from her father and one from her mother.

⇒ This suggests that Michelle's father, who is blood type A, is heter0zyg0us IAi. He must have at least one dominant allele IA that determines his phenotype, and one i allele.

⇒ Michelle's brother and sisters are also type A. They might be either h0m0zyg0us dominant IAIA or heter0zyg0us IAi.

⇒ Michelle's mother should have<u> at least </u>one recessive allele i. She could be either IAi or IBi, or ii. There are three possible option for her genotype.

Let us make the Punnet squares to understand it better. We know the genotype of the father, but there are three options for the mother.

<u>Option 1</u>

Cross)   father x mother

Parentals)  IAi     x     IAi

Gametes)  IA    i      IA     i

Punnett square)      IA       i

                       IA    IAIA    IAi

                        i     IAi       ii

F1) 25% of the progeny is expected to be h0m0zyg0us dominant IAIA

     50% of the progeny is expected to be heter0zygus IAi

     25% of the progeny is expected to be h0m0zyg0us recessive ii

75% of the progeny is expected to be blood type A ⇒ IAIA and IAi ⇒ Sisters and brother

25% of the progeny is expected to be blood tye 0 ⇒ ii ⇒ Michelle

<u>Option 2</u>

Cross)   father x mother

Parentals)  IAi     x     IBi

Gametes)  IA    i      IB     i

Punnett square)      IA       i

                       IB    IBIA    IBi

                        i     IAi       ii

F1)  25% of the progeny is expected to be IAIB

     25% of the progeny is expected to be heter0zygus IAi

     25% of the progeny is expected to be heter0zygus IBi

     25% of the progeny is expected to be h0m0zyg0us recessive ii

25% of the progeny is expected to be blood type AB ⇒ IAIB

25% of the progeny is expected to be blood type A ⇒ IAi ⇒ Sisters and brother

25% of the progeny is expected to be blood type B ⇒ IBi

25% of the progeny is expected to be blood tye 0 ⇒ ii ⇒ Michelle

<u>Option 3</u>

Cross)   father x mother

Parentals)  IAi     x     ii

Gametes)  IA    i      i     i

Punnett square)      IA       i

                        i     IAi        ii

                        i     IAi        ii

F1)  50% of the progeny is expected to be heter0zygus IAi

     25% of the progeny is expected to be h0m0zyg0us recessive ii

50% of the progeny is expected to be blood type A ⇒  IAi ⇒ Sisters and brother

50% of the progeny is expected to be blood tye 0 ⇒ ii ⇒ Michelle

Despite the fact <u>we can not determine for sure the </u><u>mother's genotype</u><u>, </u>we know that <u>she carries at least one </u><u>recessive allele</u>, which is why Michelle's blood type is 0.
