Answer:
Two members of the excavate clade that can cause disease are <u><em>diplomonads and parabasalids</em></u>
Explanation:
The excavate clade comprises of unicellular organisms which are eukaryotic. This group contains free-living organisms as well as organisms which form symbiotic relationships.
The diplomonads can be described as a group of flagellates which are considered to be parasitic. Some of them are even parasites to the humans.
The parabasalids are a group of flagellated protists within the supergroup Excavata. These organisms also form parasitic relationships.
Answer:
Spore can survive under unfavorable conditions as they are covered by a hard protective coat. Spores can grow to produce new plants and does not require sexual interaction with another organism. Due to their small size and light weight, they can be dispersed easily.
Spores can remain dormant till favourable conditions become available. b. Spores help an organism to tide over the bad phase. Spores can be spread through water, air or animals and thus is good for the spread of an organism to more places.
Explanation: hope this helps bro! (:
Answer:
Is a vicariance event
Explanation:
Even both terms are very similar, there is a difference. A dispersal event occurs when an initial specie travels from one place to another and due to the environmental factors and the adaptation that need to develop to survive will change into different species. In the other hand, the vicariance, is a process in which there is a specie and it lives in a wide are, but it fragments into groups mainly by the continental drift, so with the passing of time it turns into different characteristics, as the human race.
Answer:
Human males much more likely than human females to inherit the recessive condition hemophilia because it follows X-linked recessive pattern.
Explanation:
Actually hemophilia is an X-linked recessive disorder i-e the defective genes are located on the X chromosome (sex chromosome) and are transmitted through it. As males have only one X chromosome (inherited from mother), one altered copy of the gene in every cell cause this disease.On the other hand females have 2 X chromosomes thus this disease is rare in females.
