Answer:
Reciprocal cross
Explanation:
a reciprocal cross is a breeding experiment designed to test the role of parental sex on a given inheritance pattern. In this type of test cross, male of one genotype and female of different genotype are crossed and the opposite is true as well. ( i.e the female of one genotype and male of different genotype are crossed.)
As we can see in the male Flagus fly with the Barkus phenotype is being crossed with a female with the wild-type phenotype.
In the second test, we can see that the opposite is true of our first statement where the female Flagus fly has the Barkus phenotype and the male has the wild-type phenotype after being crossed again thereby reversing the genotype.
List three characteristics of living organisms
The following statement is false: MOST US STATES PROHIBIT THE IMPORTATION OF ANIMAL SPECIES LIKELY TO BECOME INVASIVE IF THEY ESCAPE INTO THE WILD.
Presently, most US states do not have any law, which prohibit people from bringing into the US animal species that are likely to become invasive.
Invasive plant and animals are a great source of problems in America. These species usually destroy habitats and native species, this usually throw the ecological communities out of balance. The government spend as much as $120 billions every year to control these invasive species.
Answer: Yes, because marine wildlife interacts with other marine wildlife and plant systems underwater. We could learn to manage these environments just like we do on land.
Explanation:
The question is incomplete it has options that are:
(Options for all tiles are reabsorption and secretion) Tiles- 1. Stella's urine sample shows the presence of proteins 2. Johns blood test report indicates a high toxin level 3. Miguel's blood test shows an increase in metabolic waste 4. Janice's urine report shows the presence of vital minerals
Answer:
The match of each situation is described below.
Explanation:
1. The presence of protein in Stella's urine is a indication of impaired filtration or insufficient absorption. The less reabsorption at proximal tubule causes the protein to remain in filtrate and excreting it in urine.
2. The high level of toxin in the blood test of Johns indicates that toxin are not secreted properly out of the body from kidney. Thus, less elimination of toxin increases its amount in blood.
3. The metabolic waste is excreted from the body through kidneys (excretory organ). The metabolic waste will be due to inadequate reabsorption. The kidney might fails to filter waste properly or waste gets reabsorbed can lead to its increase in Miguel's blood.
4. The maximum valuable substances for the body gets reabsorbed after filtration. This allows in retaining minerals in the body. The inadequate reabsorption can lead to release of vital minerals in Janice's urine.
