a. True
b. false
Answers
The statement "Brain changes and other biological factors may help explain why many people with schizophrenia have several key symptoms" is true.
Brain changes and other biological factors may help explain why many people with schizophrenia have several key symptoms. Schizophrenia is a chronic mental disorder that affects a person's perception of the world. It is characterized by a variety of symptoms, including delusions, hallucinations, disorganized speech and thinking, and social withdrawal, among others. Research has shown that certain biological factors, such as changes in brain structure and function, may play a role in the development of schizophrenia.
Brain imaging studies have shown that people with schizophrenia may have differences in the structure and function of various brain regions compared to people without the disorder. For example, studies have found that people with schizophrenia may have smaller brain volumes, changes in the way that different brain regions communicate with one another, and abnormalities in certain neurotransmitters (chemical messengers in the brain that help regulate mood and other functions). Overall, these changes may help explain why people with schizophrenia experience the symptoms they do.

MONOCULTURE AND THE FOOD SUPPLY
In 2011, scientists announced that the Cavendish banana, the banana that most frequently makes it to American consumers, could be wiped out by a fungus if the fungus reached fields in Latin America where the banana is grown. It had happened before with the Gros Michel banana, which was wiped out between 1906 and 1960 and is no longer grown by farmers. The reason for scientists' concern: monoculture.
Monoculture is a practice common among farmers. In most fields, you will find a single crop and these plants are not very genetically diverse. This means they are less able to adapt to environmental changes and less able to fight off diseases. Many scientists are concerned that the practice of monoculture farming means that many crops, including bananas, may be subject to total loss or even extinction.
Heirloom Plants
One way that scientists think that food supplies can be protected is by using heirloom plants. An heirloom plant is a plant that was once grown by farmers but is not used in modern monoculture farms. Many heirloom plants are more genetically diverse than modern varieties, which mean they are better able to adapt to environmental change. They are also more likely to survive an attack by a pest or infection by a disease or fungus. However, heirloom plants usually do not produce as much food as modern varieties do.
Organic Farming
Organic farming combines older agricultural practices with modern practices and does not involve the use of synthetic materials such as manmade fertilizers and pesticides. It relies on scientific knowledge about the interactions among organisms and about natural materials that can be used to fertilize plants and control pests. Organic farming does not generally involve monoculture, and an organic farm will have many different kinds of crops. Organic farming practices usually reduce the chance of total crop loss, but like heirloom plants, organic farms are often less productive than conventional farms in terms of volume of food.
Genetically Modified Organisms
Genetically modified organisms, or GMOs, are organisms that have been genetically engineered by people. Many scientists think that concerns over the risks of monoculture can be alleviated by directly changing the genes of crops. They argue that the crops can be given resistance to pests and disease, can be modified to withstand drought, and can be engineered to produce more food. However, many people are concerned about the safety of GMOs, so they are highly controversial. The technology is new and involves the use of bacteria to insert genetic material, so people are concerned that the organisms may negatively affect human health.
Because of what scientists have learned about monoculture, they are:
not pushing for a change in farming.
asking for legislation mandating GMOs.
suggesting ways to protect food supplies.
telling farmers they need to grow fewer kinds of crops.

Most fields that are irrigated year after year will eventually build up salt in the soil as water regularly evaporates and leaves some salt behind. One way farmers minimize this salt build up is to flood their fields every few years before planting. This flood water leaches out the salt in the soil. What advantages and disadvantages do you see in this approach?
Answers
Answer:
An advantage is that the salt will be washed out and a disadvantage is that it still leaves some salt behind
Explanation:
Irrigation is an agriculture practice which includes watering the cropland, this practice is advantageous as it washes the salt out of the soil however, some amount of salt still remains which affect the concentration of salts in soil.
What is irrigation?
Irrigation is the agricultural process which includes applying the controlled amounts of water to the land to assist the production of crops, as well as to grow the landscape plants and lawns in the agriculture lands. It may be known as watering in lawns. Agriculture which does not need irrigation but relies only up on the direct rainfall is referred to as rain-fed agriculture.
An advantage of the approach used in this case is that the salt will be washed out of the soil and a disadvantage of this approach is that it still leaves some salt behind in the soil which decreases the diffusion of water through roots due to increase in concentration of soil.

TRUE/FALSE. if a trait is found in both lemurs and gorillas, that trait was probably also found in the common ancestor to all primates.
Answers
TRUE. If a trait is found in both lemurs and gorillas, it is likely that the trait was also present in the common ancestor of all primates.
Explanation (100 words): Lemurs and gorillas are both primates, belonging to different primate suborders (lemurs in Strepsirrhini and gorillas in Haplorhini). They share a common evolutionary history, and any shared traits between them are likely inherited from their common primate ancestor. Traits that are present in multiple primate species indicate a deeper ancestral origin within the primate lineage. However, it is important to note that traits can also evolve independently in different primate lineages through convergent evolution or can be lost in certain species over time. Therefore, while shared traits suggest a common ancestral origin, additional genetic and evolutionary evidence is necessary to establish the exact origin and history of a specific trait among primates.

Answers
To ensure expression of the pmoCAB operon, a substance called β-galactosidase must be added to the growth media.
The term "pmoCAB operon" refers to a set of genes that are typically found in bacteria that are capable of oxidizing methane. The "pmo" in pmoCAB stands for "particulate methane monooxygenase," which is the enzyme complex that carries out the methane-to-methanol conversion. The "CAB" refers to the three protein subunits that make up the complex.
β-galactosidase is an enzyme necessary for the expression of the pmoCAB operon because it is responsible for breaking down lactose into glucose and galactose, which are then used as a source of energy for the cell.

Answers
The correct sequence for the growing tips of the root upward is: c. II, IV, I, V, III
The growing tip of a root consists of several regions, including the root cap (I), the zone of elongation (II), the zone of cell division (III), the zone of cell maturation (IV), and the apical meristem (V). These regions are arranged in a specific sequence as the root grows and elongates. The sequence starts with the zone of cell division (III), where new cells are formed by mitosis. These cells then move upward into the zone of elongation (II), where they elongate and increase in length. The region of cell maturation (IV) follows the zone of elongation and is where cells differentiate into their specific cell types. The root cap (I) covers the tip of the root and helps to protect it as it grows through the soil. Finally, the apical meristem (V) is located at the very tip of the root and is responsible for producing new cells and driving the growth of the root.
Therefore, the correct sequence for the growing tips of the root upward is II, IV, I, V, III.

The stage of the stress response in which the pituitary gland releases a flood of adrenocorticotropic hormones is
Answers
Answer:
This is Alarm.
Explanation:
Adrenocorticotropic hormones and stress.
This the hormones secreted at the corticotrophs cells of the anterior pituitary glands.Its major function is to ensure the efficient functioning of the Adrenal gland and body response to stress.It is also mediate the secretion of cortisol from the cortex of the adrenal gland into the blood stream.When it is released into the blood streams it binds to the receptors in the adrenal gland to stimulate the release of cortisol hormone.
ACTH controls diurnal (circadian) rhythm in human.This is because it peaks in the morning and progressively reduced towards the end of the day,with lowest concentration during period of sleeping.
Generally stress either by dehydration or internal complications,leads to increase in solute potential of the blood.Stress increases the activation of ACTH from the adrenal gland while boosting the concentration of cortisol. When the stress is sensed by the brain,this causes the release of corticotrophin-releasing hormone into the bllood.
The latter cause the discharge into the blood stream of ACTH via hypothalamic–pituitary–adrenal (HPA) axis.As this enters the blood it binds to the receptors for the cortisol secretions in the cortex of the adrenal gland to produce cortisol as explained earlier.Cortisol is the primary sex hormone which create the alarm.

The myelin sheath, which surrounds the axons that make up the white matter of the nervous system, is a crucial component.
The Schwann cells in the peripheral nervous system create this myelin sheath.
The innermost sheet-like glial process in touch with the axon spirals around it and spins out several overlapping membrane layers to generate myelin in the PNS (peripheral nervous system) and CNS. All save the innermost and outermost layers of the myelin sheath experience cytoplasm expulsion.
Around nerves, particularly those in the brain and spinal cord, a shield or sheath known as myelin forms. Protein and fatty acids make up its structure. The myelin sheath allows electrical impulses to travel along nerve cells efficiently and quickly. When myelin is compromised, these impulses become slower.

When streaking a throat culture on blood agar, stabbing the agar plate provides detection for Streptolysin O Bile solubility Streptolysin S DNase activity 100
Answers
When streaking a throat culture on blood agar, stabbing the agar plate provides detection for Streptolysin O. The stabbing method is also called the puncture method, and it helps in determining Streptococcus pyogenes' hemolytic activity.
Streptococcus pyogenes produces two hemolytic toxins, streptolysin O (SLO) and streptolysin S (SLS). These toxins are necessary for establishing an infection.
The throat culture on blood agar plate is used to diagnose a throat infection. The process of inoculation involves streaking and stabbing.
Streaking is performed by moving the swab back and forth over the surface of the agar. It helps in identifying the colonies that have formed on the agar's surface.
On the other hand, stabbing is done by inserting the swab into the agar medium and then withdrawing it. It is useful for detecting the presence of hemolytic toxins.
In case of streptococcal infection, the throat culture is used to detect SLO activity. SLO causes beta-hemolysis, which is visible as a clear zone around the colonies.
By stabbing the agar plate, the SLO remains within the colony, resulting in no hemolysis around the colony. However, if the colonies are streaked on the surface, SLO diffuses out of the colony, causing beta-hemolysis.
Therefore, by stabbing the agar plate, it helps in detecting SLO activity.
