Answer:
1 in 2
Explanation:
Twin studies show that if a monozygotic twin has schizophrenia then there is a __1 in 2___ chance the other twin will develop the disorder.
If a monozygotic twin has schizophrenia, the chance the other twin will develop the disorder is 40-60%. This result from twin studies is indicative of the genetic influence on the disorder, but environmental factors also play a significant role.
The subject of this question is on the heritability of schizophrenia in monozygotic twins, otherwise known as identical twins. Twin studies have shown that if one twin has schizophrenia, the probability of the other twin also developing the disorder is approximately 40-60%.
This is known as the concordance rate for schizophrenia among monozygotic twins.
It's important to understand that even though monozygotic twins share the same genetic material, the manifestation of schizophrenia in both twins is not guaranteed due to environmental influences and possible gene-environment interactions.

2 : production of energy
3 : replication of genetic material
4 : recognition of certain chemicals
Cell membrane helps in the recognition of certain chemicals.
Further Explanation:
Plasma membrane is an outer boundary of the cell. It is composed of phospholipids and proteins. It is also called selectively permeable membrane because it allows only selective substances to cross. The transportation of these molecules from extracellular fluid to intracellular fluid is called cellular transport. It can be active and passive transport. Active transport required energy for the movement of substances, whereas in passive transport the molecules move across the membrane without using energy.
There are three common cellular substances that can pass through cell membrane are water, carbon di-oxide and oxygen. These substances are transported through passive transport. The carbon di-oxide and oxygen move through the area of higher concentration to lower concentration. The oxygen diffuses into the cell through lipid bilayer because it is more concentrated outside the cell, whereas carbon dioxide diffuses out of the cell because it is more concentrated inside the cell.
Water moves through the membrane by the process called osmosis. It moves freely either through protein channels or by slipping between the lipid tails of the membrane. The water comes from higher concentration to lower concentration.

The cell membrane functions to recognize certain chemicals. Option 4 is correct.
Carbohydrates, proteins, and lipids are found on the cell membrane. Carbohydrates are covalently attached to proteins on the cell membrane to form glycoproteins. Lipids are attached to glycoproteins to form glycolic acid. These are called membrane carbohydrates. Most membrane carbohydrates are found on the surface of the cell and extend to the extracellular compartment. These membrane carbohydrates play an important role in the recognition of cells.

(B) The opposite is true, too - when genes from a goat are inserted into a spider's genome, the spider produces goats' milk instead of silk.
(C) The proteins in goats' milk and spiders' silk have the same amino acid sequence
(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.
(E)The processes of transcription and translation in the cells of spiders and goats produce exactly the same proteins anyway.
Answer:
(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.
Explanation:
The genetic information present in the spider DNA can be inserted, transcribed and translated using similar machineries to that present in spiders. This produces the same protein, but the protein is likely processed and exported differently, meaning it plays different roles in each organism.
This is true for lots of scenarios, scientists frequently insert human genes into mice, and even cells in culture!
Across nearly seven million years, the human brain has tripled in size. The most likely the reason for the evolution of a larger brain in humans is that a larger brain allows humans to solve complex problems. Large, complex brains enable humans to process and store a lot of information and to interact with each other and with their surroundings better. The brain we now humans have is the largest and most complex of any living primate.
