Leo Kanner differentiated autism from schizophrenia in all areas except one: the age of onset. Kanner observed and described a distinct set of characteristics and behaviors in children that he termed "early infantile autism." He published his landmark paper on autism in 1943.
While Kanner identified several key differences between autism and schizophrenia, the age of onset was not one of them. Initially, Kanner believed that autism manifested in early childhood, specifically in the first few months of life.
However, further research and understanding of autism have since shown that it typically becomes apparent during early childhood, around the age of 2 to 3 years.
The differentiation between autism and schizophrenia lies in various other areas, including the nature of social and communication difficulties, repetitive behaviors, and the lack of hallucinations or delusions typically seen in schizophrenia.
Kanner's observations helped establish autism as a distinct condition separate from schizophrenia and laid the foundation for further research and understanding of autism spectrum disorders.

An ecosystem such as a forest in the Pacific Northwest of the United States is made up of a complex community of living organisms and their interactions with each other and their physical environment. Some of the key components of this ecosystem include:
Producers: These are the organisms that produce organic matter from sunlight and carbon dioxide through photosynthesis. In a forest ecosystem, the dominant producers are typically trees such as Douglas fir, western red cedar, and Sitka spruce.
Consumers: These are the organisms that consume other organisms for energy and nutrients.
In a forest ecosystem, consumers can include herbivores such as deer and elk, carnivores such as cougars and bears, and omnivores such as raccoons and coyotes.
Decomposers: These are the organisms that break down dead organic matter and recycle nutrients back into the ecosystem. In a forest ecosystem, decomposers can include fungi, bacteria, and detritivores such as earthworms and millipedes.
Abiotic factors: These are the non-living components of the ecosystem, including climate, soil, water, and air. In a forest ecosystem, abiotic factors can include temperature, precipitation, soil type, and topography.
All of these components interact with each other in complex ways to create a dynamic and interconnected ecosystem.
For example, trees provide habitat for birds and other animals, which in turn can disperse seeds and pollen and help to pollinate the forest.
Decomposers break down dead plant matter and recycle nutrients back into the soil, which can help to support the growth of new plants.
The physical characteristics of the forest, such as soil type and topography, can also affect the types of organisms that are able to thrive in the ecosystem.

Girls who begin puberty late tend to go through the changes at _____ rate.
A) a faster
B) a slower
C) the same
D) a strange
Girls who begin puberty late tend to go through the changes at a slower rate. The correct option is B.
Puberty is a complex process that involves various physical and hormonal changes that prepare the body for reproduction. The onset of puberty is influenced by various factors such as genetics, nutrition, and environmental factors.
Girls who start puberty later than their peers may feel self-conscious or worried about their development. However, it's important to note that the late onset of puberty is not necessarily a cause for concern, and it's a relatively common occurrence. In fact, studies have shown that girls who start puberty later tend to have a slower rate of progression through the different stages of puberty.
This slower rate of progression can have both positive and negative effects. On the one hand, it may give girls more time to adjust to the physical and emotional changes of puberty. On the other hand, it may prolong the discomfort or awkwardness of puberty, as well as delay the attainment of reproductive maturity.

mirnas can control gene expression by what action? see concept 18.3 (page 377)
miRNAs can control gene expression by binding to the mRNA molecule and either degrading it or preventing it from being translated into a protein. This process is known as post-transcriptional gene silencing and allows miRNAs to regulate the levels of proteins produced by specific genes.
Hi! miRNAs (microRNAs) can control gene expression through a process called RNA interference (RNAi). Here's a step-by-step explanation:
1. miRNAs are small non-coding RNA molecules that are transcribed from genes in the cell.
2. These miRNA molecules are processed into mature, single-stranded RNA molecules by cellular machinery.
3. The mature miRNA binds to a protein complex called RISC (RNA-induced silencing complex).
4. The miRNA-RISC complex then interacts with specific target mRNA molecules, which are the products of gene expression.
5. This interaction results in either the degradation of the target mRNA or the inhibition of translation (protein synthesis), effectively silencing the expression of the target gene.
So, miRNAs can control gene expression by either degrading the mRNA or inhibiting translation, ultimately preventing the production of proteins from the targeted genes.

Which of the following represents an indirect measure of the amount of energy released from food?
A) The increase in heat given off when the food is burned
B) Quantity of oxygen consumed when the food is burned
C) Quantity of carbon dioxide consumed when the food is burned
D) The increase in heat retained by the food when it is slowly brought to 100° C
The correct answer is B) Quantity of oxygen consumed when the food is burned.
An indirect measure of the amount of energy released from food is the quantity of oxygen consumed when the food is burned. This is because when food is burned (oxidized), it releases energy in the form of heat. The amount of oxygen consumed during this process is proportional to the energy released. Thus, by measuring the quantity of oxygen consumed, we can indirectly determine the amount of energy released from the food.
The quantity of oxygen required to metabolise food and the amount of energy generated from that meal are directly correlated, according to scientists. In other words, more energy is released when a particular amount of food is broken down with more oxygen. So, if we measure how much oxygen is used during the burning of food, we may indirectly determine how much energy is liberated from that meal.
Because of this, the amount of oxygen used during the burning of food serves as a proxy for the amount of energy it releases. Scientists can determine how many calories are in a certain food by measuring the quantity of oxygen consumed during metabolism.

during meiosis, a nondisjunction event results in a gamete with one too few chromosomes. after fertilization of that abnormal gamete with a normal gamete, the resulting human zygote will have how many chromosomes?
After fertilization with a normal gamete, a human zygote resulting from a nondisjunction event during meiosis will have 46 chromosomes.
When a nondisjunction event occurs during meiosis, it means that chromosomes fail to separate properly, resulting in a gamete with an abnormal number of chromosomes. In this case, a gamete with one too few chromosomes will be produced. This gamete will have 23 chromosomes instead of the normal 24.
After fertilization with a normal gamete, the resulting human zygote will have 46 chromosomes, which is the normal number of chromosomes in a human cell. This is because the normal gamete will contribute its 23 chromosomes to the zygote, which will combine with the 23 chromosomes from the abnormal gamete.
It's worth noting that nondisjunction events can also result in gametes with one too many chromosomes, which can also lead to genetic disorders in the resulting zygote. These disorders can include Down syndrome, Turner syndrome, and Klinefelter syndrome, among others.

The gene for color blindness is located on the X chromosome, and since males only have one X chromosome, they are more likely to be affected by X-linked recessive disorders. Females have two X chromosomes, so they can be carriers of the color-blindness gene without actually being color-blind themselves, although in rare cases they can be affected if they inherit the gene from both parents.
Color blindness is an X-linked recessive genetic disorder that affects the perception of color. The gene for color vision is located on the X chromosome, and since males have only one X chromosome, they are more likely to be affected by X-linked recessive disorders like color blindness. Females, on the other hand, have two X chromosomes, so they can be carriers of the color-blindness gene without being affected themselves.
If a normal couple has a color-blind child, this indicates that the mother is a carrier of the color-blindness gene on one of her X chromosomes. Each of her sons has a 50% chance of inheriting the color-blindness gene and being color-blind. Her daughters have a 50% chance of inheriting the gene and being carriers, but they would not be color-blind themselves unless they inherit the gene from both parents.
It's important to note that there are different types and degrees of color blindness, depending on which cone cells are affected. Red-green color blindness is the most common form, affecting about 8% of males and 0.5% of females of Northern European descent. Blue-yellow color blindness and complete color blindness (achromatopsia) are much rarer.
