The answer is Condenser. It is a small non non-magnifying lens system that condenses light before it passes through the specimen. Concentrates light on the specimen. Located beneath the stage. First, the iris diaphragm creates an aperture that regulates the amount of light passing through the condenser and ultimately the ocular lenses.

The question is the following :
<span>What is the best evidence to prove that Irene was heterozygous for hemophilia?
A) Alice carried the recessive allele.
B) Alexandra carried the recessive allele.
C) Frederick carried the recessive allele.
D) Waldemar carried the recessive allele.


The correct answer is A

In the pedigree, marked with blue are the carriers of the X recessive allele ( they have one X that has the mutation and the other that doesn't).
Alice was Irene's' mother, and since both Alice and iIrene have the allele, it is safe to conclude that Irene inherited the recessive allele from Alice.</span>

Temka [501]

Answer:

2Major Structures and Functions of the Brain

Publication Details

Outside the specialized world of neuroanatomy and for most of the uses of daily life, the brain is more or less an abstract entity. We do not experience our brain as an assembly of physical structures (nor would we wish to, perhaps); if we envision it at all, we are likely to see it as a large, rounded walnut, grayish in color.

This schematic image refers mainly to the cerebral cortex, the outermost layer that overlies most of the other brain structures like a fantastically wrinkled tissue wrapped around an orange. The preponderance of the cerebral cortex (which, with its supporting structures, makes up approximately 80 percent of the brain's total volume) is actually a recent development in the course of evolution. The cortex contains the physical structures responsible for most of what we call ''brainwork": cognition, mental imagery, the highly sophisticated processing of visual information, and the ability to produce and understand language. But underneath this layer reside many other specialized structures that are essential for movement, consciousness, sexuality, the action of our five senses, and more—all equally valuable to human existence. Indeed, in strictly biological terms, these structures can claim priority over the cerebral cortex. In the growth of the individual embryo, as well as in evolutionary history, the brain develops roughly from the base of the skull up and out ward. The human brain actually has its beginnings, in the four-week-old embryo, as a simple series of bulges at one end of the neural tube.
