Answer:

1. What is the relationship between body shape and the habitat where they are most commonly found?

2. What is the difference between toads having a thicker skin than frogs?  

Explanation:

<u>Toads and frogs are amphibians that belong to the same family, live in lakes, rivers and wetlands and have some similar characteristics</u>. Among their main differences are:

  • The skin of toads is rougher, drier and rougher. While frog skin is moist and smooth.
  • Frogs live in humid areas, although they can go out to dry land for food. Whereas toads can survive longer on the ground away from moisture, as they have greater water control in the body.
  • Frogs are characterized by long limbs that favor long hopping and swimming. On the other hand, toads have shorter legs.
  • Toads tend to be more rounded, muscular and stocky. Frogs tend to be more slender.
  • Most toads are poisonous. In contrast in frogs, not all species are poisonous.

Given these observations, two questions that may arise could be:

1. What is the relationship between body shape and the habitat where they are most commonly found? This is that frogs have longer legs which helps them to swim and that is why they are more commonly found in water. While toads have shorter legs that even allow them to burrow into the ground, they can survive longer on land.

2. What is the difference between toads having a thicker skin than frogs?  Toads have thicker and more impermeable skin than frogs, which allows them to live in drier places. Also, the blood of the toad is of higher osmotic concentration than water.

A great deal of the Blue Ridge was eroded. The eroded rock eventually finally settled in Virginia’s coastal plain. What process
Lisa [10]
The process is called Erosion. During the Erosion, materials from one place such as soil and rocks will be transport to another location.

A cross was made between a white male dog and two different black females. the first female gave birth to eight black pups, and
Svetradugi [14.3K]

In this case, the black body colour is the dominant one. The white dog is  homozygous recessive.

As the cross between the black female 2 and the white male results in all black pups. This means that the all the offsprings are heterozygotes and the Female 1 is homozygous recessive having a BB phenotype (where B codes for dominant allele).

As the cross between the black female and the white male results in four white and three black pups. This means that the all the black offsprings are heterozygotes, and the white ones are homozygous recessive and the Female 2 have a dominant and 1 recessive gene, and is a hetrozygotezygous recessive having a Bb phenotype (where B codes for dominant allele and b codes for recessive allele).

Which organs are responsible for destroying old red blood cells?
Elan Coil [88]
<span>Spleen is also known as the graveyard of RBC, if it helps u 

1.Stem cells in bone marrow make all blood cells. RBC lives about 120 days. 
RBC are destroyed in Spleen. This process takes place as: 
- RBCs are ruptured. 
- Heme and globin portions separated. 
- Globin > amino acids. 
- Iron transferred in transferrin into the blood > into bone marrow for reuse. 
- Heme > Biliverdin > Bilirubin > liver >small intestine. 



2.Reticuloendothelial cells participate in the destruction of senescent RBC's. The spleen is a well suited site of RBC destruction given that cells must course through 2-3 micron apertures in the walls of splenic sinusoids, which is an ultimate test of cell pliability. Rigid cells are entrapped and phagocytosed. Intra-erythrocyte inclusions are removed during splenic circulation. 
Destruction of RBCs happens within reticuloendothelial cells – NOT in the circulation. Globin and heme get recycled, porphyrin is degraded to bilirubin which is conjugated by the liver and excreted in the gut. Rate limiting step is conjugation. Indirect (unconjugated) bilirubin is result if this doesn’t happen. 
Normally ~10% RBCs lyse while in circulation Þ Hgb gets released into circulation and rapidly disassociates into alpha and beta dimers which are bound by haptoglobin. The Hgb/haptoglobin complex is transported to the liver. If haptoglobin is depleted, free Hgb circulates and is filtered by the kidney. Free Hgb is either reabsorbed by renal tubular cells or excreted as free Hgb in the urine. 


3. Another site reported that 
RBC destroyed in liver and spleen, by macrophages. 2 million destroyed per second. 
Hb is released and iron is recovered and returned to bone marrow.</span>

It is never optimal to exercise an American call option on a non-dividend paying stock early. True or false?
Serga [27]

Answer:

False
