Answer:
all 20
Explanation:
It is impossible to know how many individuals will have the disease at the end without knowing other factors such as the condition where the subjects are being held, trial specifications and safety measures, etc. Based on the information provided, the best prediction that can be made is that all 20 subjects will have the disease. This is because since none of them are immune the disease will spread between the patients/subjects through contact or testing equipment.
Answer:
The correct answer is: c) 3, 2, 5, 1, 4.
Explanation:
Endochondral ossification is the process in which <u>bone tissue is formed from a cartilage model</u>, unlike intramembranous ossification in which bone cells originate from mesenchymal stem cells. Endochondral ossification is key to: 1) the rudimentary formation of long bones, 2) the growth in lenght of long bones, and 3) the reparation if bone tissue when the bone is fractured.
Answer:
When many different species live in an environment, the environment has high<em> biodiversity</em>. If the number of predators increase in an area, the immediate effect will be a<em> unstable ecosystem (</em><em>decrease in the population of prey</em>.)
Explanation:
In ecology, biodiversity can be described as the different plants and animals which live in a habitat. If a habitat has many kind of different species, then the habitat or ecosystem will have a wide biodiversity. The wider the biodiversity, the more stable an ecosystem will be.
If the number of predators will increase then the ecosystem will become unstable. There will be more competition for resources.
Answer:
Homozygous recessive
Explanation:
The parents of the individual displaying the sickle cell anemia (SS) are phenotypically normal parents meaning, both parents are carriers of the (AS) gene which is a recessive trait for sickle cell anemia.
The individual took up the SS allele from both parents which makes him/her homozygous recessive. An individual is said to be homozygous recessive if that individual carries two copies of the same recessive allele.
Homozygous dominant is when an individual carries two copies of the same dominant allele (e.g AA).
