Identify Causes: What are some factors that might cause changes in the population of grasshoppers?

Biology
1 answer:
zubka84 [21]2 years ago

Answer:

Empty calories may be grasshoppers' downfall.

Explanation:

Many insect populations are declining, and a provocative new hypothesis suggests one problem is that rising levels of atmospheric carbon dioxide (CO2) are making plants less nutritious. That could spell trouble not just for insects, but for plant eaters of all sizes.

Answer:

Our immune system produces antibodies against that antigen of pathogen.

Explanation:

Injecting an antigen from a pathogen would help our immune system memorize the infection and protect our body from causing of the disease because our immune system produces antibodies against that antigen so when the pathogen enters our body these antibodies attack on that and prevent them of causing infection in the body so that's why injecting an  antigen has to be done from the childhood to prevent diseases.

The pedigree below tracks the presence of dimples through a family's generation. Having dimples is an autosomal dominant trait.
yulyashka [42]

A pedigree is a representation of a family history tracking a trait. The graph shows the inheritance pattern of the trait and its expression through several generations.

<h3>What is an autosomal dominant trait?</h3>

The autosomal dominant trait is the characteristic that is coded by a gene located in an autosomal chromosome (this is, not a sexual chromosome).

This trait is dominant because it is coded by the dominant allele, meaning that the recessive allele codes for the absence of dimples. The presence of only one dominant allele in the genotype is enough for the idividual to express dimples.

<u>               Genotype                                  Phenotype     </u>

DD, Homozygous dominant                        Dimples

Dd, Heterozygous                                        Dimples

dd, Homozygous recessive                       No Dimples

<h3>What is a pedigree?</h3>

The pedigree is the representation of a family history conserning a certain trait. In this case, dimples.

The pedigree shows the expression -and inheritance pattern- of the trait through several generations.

To correctly interpret a pedigree, we need to know that

  • Family members

→ Individuals are represented with geometrical figures.

→ Males are squares

→ Females are circles

  • Trait/Phenotype

→ Healthy/normal/not affected  individuals are represented with empty figures

→ Affected/mutated individuals are represented with solid black figures

  • Generations

→ Each file is represented with a roman number, indicating the Generation.

Here we will assume that

  • Individuals represented with solid figures express dimples -shaded individuals-. They can be either DD or Dd. This is because dimples is not usuall.
  • Individuals with no dimples are represented with empty figures and are dd.

According to the provided pedigree,

I-1 ⇒ man DD or Dd

I-2 ⇒ woman dd

II-1 ⇒ man Dd or DD

II-2 ⇒ woman dd

II - 5 ⇒ woman dd

III - 1 ⇒ man Dd

III- 2 ⇒ woman dd

III - 6 ⇒ woman dd

Since this pedigree does not specify the relationship between individuals, I can not answer the question based on it. So, I will attach another tree to specify genotypes.

I advise you study this new example, and then follow the same reasoning to choose the correct individual according to you pedigree.
