The answer is Porifera.
Porifera is phylum that includes sponges. <span>Their body is full of holes and it is easily for water to enter and exit these holes. </span>Sponges are commonly used for washing the dishes, but it is most likely that these are artificial sponges. Still, they are made modeled by real sponges. Rarely, the real sponges are used as bath or dish washing.
Answer:
A. the heterozygote advantage
Explanation:
Heterozygote advantage is the condition where the heterozygous individual has higher relative fitness than both homozygous dominant and homozygous recessive individual. This means that the heterozygote individual has higher chances of surviving than both the homozygous counterparts. Sickle cell anemia is a recessive inherited disorder in which oxygen carrying hemoglobin has an abnormal structure. Hence, the resultant RBCs are not spherical but have crescent sickle shape. The oxygen carrying capacity of such RBCs is drastically reduced but they are unaffected by malarial parasite due to their abnormal structure.
- A person with both the recessive genes for sickle cell would not be able to survive due to insufficient oxygen transport in body.
- A person with both the dominant genes would be free of sickle cell anemia but in case of malaria would not be able to survive as the normal RBCs would be hijacked by the parasite.
- A hetrerozygote would survive both in malaria and sickle cell condition since he has enough normal RBCs for oxygen transport but also has sickle cell RBCs which are unaffected by malarial parasite.
Answer:
Option "B & C"
B: One structural difference between the two species is the reduced size of the island fox, a feature known as dwarfism.
C: The various island subspecies also differ from each other in size, number of tail vertebrae, and other characteristics.
Explanation:
One notable difference between gray foxes and island foxes is the small size of island foxes. This character (dwarfism) was exhibited by the common ancestor of all six island fox subspecies. Note that the northern Channel Island fox subspecies are more closely related to each other than to any of the southern subspecies, and that the southern subspecies are more closely related to each other than to the northern subspecies.
For a human offspring to express a paternal mitochondrial gene, the individual must have inherited a mitochondrion from the sperm this is called paternal leakage.
<h3>What is mitochondrial diseases ?</h3>
A disease that develops when cellular energy production systems are broken.
The mitochondria's inability to fully burn nutrients and oxygen to produce energy, which is necessary for healthy cell function, is a common factor across mitochondrial disorders. It's frequently inherited.
Muscle weakness, developmental delays, and poor growth are possible symptoms. Although there is no cure, symptoms can be managed with medicine and physical therapy.
<h3>Causes of mitochondrial myopathies</h3>
Genetic mutations lead to mitochondrial disorders. Proteins are made according to instructions provided by genes, and the genes causing mitochondrial illness typically produce proteins that function inside mitochondria.
