Answer:
The correct option is <em>lower.</em>
Explanation:
Schizophrenia can be described as an inherited disease and it is a type of mental illness. As Armend has an identical twin brother with diagnosis of schizophrenia hence, he will have more chances than Robert whose fraternal twin sister has schizophrenia.
As fraternal twins develop from two different eggs hence, the chances in them having the same disease will be lower. Identical twins develop from the same egg, hence they will have more chances of having the same inherited disease.
Answer:
Option B, Observation 2
Explanation:
The four main observation of Darwin’s areas follows –
Observation 1 – Variation occurs in the species with time leading to evolution. Offspring of two parents vary distinctly in traits such as height, color, weight etc. These variations are also affected by the surrounding environment
Observation 2-
Based on observation 1, Darwin concluded that offspring inherit traits from their parents. These traits improve the odds of survival and only genetic traits will be passed. Traits developed in an individual due to environment will not be passed on.
Observation 3 –
Offspring compete among themselves to survive.
Observation 4
The fittest among the competing species for survival will survive and pass on its traits to the next generation.
Since here the Pigeon breeders want to exemplify the looks (a genetic trait) of parents to their offspring, observation 2 applies here
Hence, observation b is correct
Answer:
Due to the presence of limited number of species.
Explanation:
Bear island provide a great opportunity to decipher entire food chains because this island has many animals species which interact with each other or depend on one another due to the presence of less animals for feeding purpose. This island is isolated from the rest of the world so it provide a great opportunity to study the entire food chains that are present at that island. There is less number of species so knowing about their feeding choices is easier for the ecologists.
Answer:
Her minimum height must be 5'5" and her minimum weight must be 150 lb
Explanation:
The double red program is a program where red blood cells are donated by people . This red blood cells are used for treatment of patients that require red blood cells such as transplant of organs, transplant of tissues, treatment of cancer e.t.c.
Apheresis is a process whereby blood is collected or removed from the body and it undergoes the process of filtration into various components of the blood.
The machine that is used during apheresis collects the human blood and separates it into white blood cells, red blood cells and platelets.
Answer:
B. A proton gradient drives the formation of ATP from ADP and inorganic phosphate via ATP synthase.
Explanation:
Light reaction of photosynthesis includes the splitting of water in the presence of sunlight and electron transfer from PSII to PSI via an electron transport system. During the transfer of electron through cytochrome of the electron transport system, the proton concentration gradient is generated across thylakoids. The proton concentration gradient is harvested to drive ADP phosphorylation by the catalytic site of ATP synthase accompanied by downhill movement protons through its proton channels.
