AlekseyPX

Answer:

the smell or taste of chicken salad

Explanation:

  • A conditioned stimulus is the one which was previously a neutral stimulus but hen it gets paired with the unconditioned stimulus it leads to a conditioned response.
  • The learned response which is produced in response to a neutral stimulus is the conditioned response.
  • In the given condition the smell or taste of a chicken salad causes Allison to feel nauseated and hence, the taste or smell of a chicken salad is the conditioned stimulus which generates a conditioned response which in this case is nausea.

Explain how chromosome behavior during meiosis ensures transfer of parental traits to offspring
gizmo_the_mogwai [7]

Explanation:

During meiosis, sister chromosomes of a homologous pair separate into different cells during gamete formation . This mainly occurs in Metaphase I of meiosis where the homologous chromosomes line up the metaphase plate in their sets. Each chromosomes of a pair are then pulled to different poles of the cells separating them. Each of these chromosomes carries a set of alleles of a gene. Each cell/gamete, therefore, carried half the set of alleles of all genes compared to autosomal cells. There many combinations of these sets that can occur depending on the number of chromosomes the organism has.

These cells when combined with that of another parent during fertilization, form a zygote that grows and develops into a mature organism. The offspring will bear the characteristics of both parents because it inherits half a set of chromosomes from both parents.

How does homeostasis work in both prokaryotic and eukaryotic cells?
Roman55 [17]

The process of passing genetic material from one generation to the next depends completely on how cells grow and divide. To reproduce, a simple organism such as bacteria or yeast simply copies its DNA (through a process called replication) and splits in two. But organisms that reproduce sexually go through a complicated dance that includes mixing and matching strands of DNA (a process called recombination) and then reducing the amount of DNA in special sex cells to arrive at completely new genetic combinations for their offspring.

There are two basic kinds of organisms — ones with a nucleus and those without a nucleus (a compartment filled with DNA surrounded by a membrane called a nuclear envelope):

<span>Prokaryotes: Organisms whose cells lack a nucleus and therefore have DNA floating loosely in the liquid center of the cell. Prokaryotes divide, and thus reproduce, by simple mitosis.</span><span>Eukaryotes: Organisms that have a well-defined nucleus to house and protect the DNA. Eukaryotes divide by meiosis for sexual reproduction.</span>

explain how having a haploid number of chromosomes contributes to the function of gametes in a life cycle
kotegsom [21]
Having the haploid number of chromosomes allows the zygote to have the correct number. If gametes weren't haploid, every generation of organisms would have twice as many chromosomes as their parents. I hope my answer has come to your help. God bless and have a nice day ahead!

What are the 5 functions of nematodes in the soil
11Alexandr11 [23.1K]

Nematodes are wormlike organisms which can be seen with naked eye, live in water-filled pore spaces in the soil. Nematodes are in large number in the upper soil layers where organic matter, plant roots, and other resources are most abundant.

The functions of nematodes:

  • Free-living nematodes decompose organic material into nutrients and cycled them in the soil by feeding on some bacteria and fungi.
  • Nematodes help in distributing bacteria and fungi through the soil and along roots by carrying live and dormant microbes.
  • They used as food for higher predators, soil microorthropodes.
  • They eat disease-causing organisms, thus suppress their growth.
  • They acts as potential bio- control agents.
