Answers

The protein needs of an infant are about twice as much per pound of body weight as adults, option (c) is correct.

During infancy, protein plays a critical role in supporting rapid growth and development. Infants require higher amounts of protein to support the growth of tissues, muscles, and organs compared to adults. The recommended protein intake is approximately 2 grams per kilogram of body weight in an infant, whereas adults typically require around 0.8 grams per kilogram.

This higher protein requirement for infants reflects their accelerated growth rate during the early stages of life. Adequate protein intake is essential for meeting the nutritional needs of infants and supporting their overall growth and development, option (c) is correct.

which of the following are reasons for weight increase, apart from diet and exercise?

Answers

There are several reasons for weight increase apart from diet and exercise, such as hormonal imbalances, medication side effects, genetics, stress, lack of sleep, and underlying medical conditions.

Apart from diet and exercise, some other reasons for weight increase can include:

1. Hormonal imbalances: Conditions like hypothyroidism, polycystic ovary syndrome (PCOS), and insulin resistance can cause weight gain.

2. Medications: Certain medications, such as antidepressants, steroids, and some blood pressure medications, can contribute to weight gain.

3. Sleep deprivation: Inadequate sleep can lead to hormonal imbalances, which can cause weight gain. It's important to get enough sleep for your overall health.

4. Stress: Chronic stress can lead to weight gain as the body releases cortisol, a hormone that can cause increased appetite and fat storage.

5. Aging: As you age, your metabolism naturally slows down, which can lead to weight gain if you don't adjust your diet and exercise accordingly.

6. Medical conditions: Some medical conditions like Cushing's syndrome, Prader-Willi syndrome, and other genetic disorders can cause weight gain.

Remember that maintaining a healthy weight involves a combination of a balanced diet, regular exercise, and addressing any underlying issues that may be contributing to weight gain.

Most authorities agree that the biggest obstacle faced by persons with deaf-blindness is a) self-help skills. b) accessing information.

Answers

When it comes to individuals with deaf-blindness, the biggest obstacle they face is generally agreed to be accessing information.

Since these individuals cannot rely on either sight or sound, they need alternative methods to access information such as braille, sign language, or auditory devices. This can pose challenges when it comes to communication and accessing information independently. Self-help skills, on the other hand, while also important, can often be developed with the right support and training. With access to information and communication methods, individuals with deaf-blindness can gain more independence and improve their overall quality of life. It is essential to provide appropriate resources and support to help overcome these challenges.

Most authorities agree that the biggest obstacle faced by persons with deaf-blindness is b) accessing information. Deaf-blind individuals encounter challenges in receiving and processing data from their surroundings. This impacts their communication, mobility, and ability to participate in daily activities. Although self-help skills are essential, accessing information remains a critical barrier that influences their overall quality of life and independence.

which alteration in the body is prominent when there is a rise in body temperature?

Answers

Answer:

When there is a rise in body temperature, the most prominent alteration in the body is an increase in metabolic rate.

Explanation:

This implies that the body's cells are working harder to produce energy and maintain cellular function, generating more heat. The body responds to this increase in temperature by activating the sweat glands, which release sweat onto the skin. As the sweat evaporates, it carries away heat from the body, lowering the body temperature. Additionally, the blood vessels in the skin dilate, allowing more blood to flow near the surface of the skin, dissipating heat. These processes are regulated by the hypothalamus in the brain, which acts as the body's thermostat to maintain a constant internal temperature. If the rise in body temperature persists unregulated, it can cause heat exhaustion or heat stroke, which can be serious and even life-threatening.

insoluble fiber in the diet is better at better at providing bulk and stimulating peristaltic action than soluble fiber. a. true b. false

Answers

Insoluble fiber in the diet is better at better at providing bulk and stimulating peristaltic action than soluble fiber is a false statement.

Plant components that are not broken down by human digestive enzymes are considered to be dietary fiber. Only lignin and a few polysaccharides were known to meet this definition in the late 20th century; however, resistant starch and oligosaccharides were included as dietary fiber components in the early 21st century. All polysaccharides and lignin that are not digested by the human digestive tract's endogenous secretion are included in the most common definition of dietary fiber.

In Commonwealth English, the portion of plant-derived food that cannot be completely broken down by human digestive enzymes is called dietary fiber, or roughage. Dietary filaments are assorted in synthetic piece, and can be gathered commonly by their dissolvability, consistency, and fermentability, which influence how strands are handled in the body. There are two main components to dietary fiber: soluble and insoluble fiber, which are found in legumes, whole grains, cereals, vegetables, fruits, and nuts or seeds, among other plant-based foods.

The consumption of a diet rich in fiber on a regular basis is generally linked to improved health and a lower risk of several diseases. Dietary fiber comprises of non-starch polysaccharides and other plant parts like cellulose, safe starch, safe dextrins, inulin, lignins, chitins (in parasites), gelatins, beta-glucans, and oligosaccharides.

what type of fatigue is caused by prolonged illness or poor nutrition which weakens the immune system

Answers

The type of fatigue caused by prolonged illness or poor nutrition which weakens the immune system is known as chronic fatigue.

Chronic fatigue is a debilitating condition that is characterized by extreme tiredness, weakness, and exhaustion that persists for an extended period, typically six months or longer. This condition can be caused by a range of underlying factors such as viral infections, autoimmune disorders, hormonal imbalances, and poor nutritional intake.
When the immune system is weakened due to prolonged illness or poor nutrition, the body's ability to fight off infections and diseases is compromised. This can result in a vicious cycle where the body becomes increasingly fatigued, making it harder for the immune system to function correctly, further exacerbating the condition. Chronic fatigue can lead to a range of physical and mental health problems such as depression, anxiety, muscle pain, and brain fog, among others.
To address chronic fatigue caused by prolonged illness or poor nutrition, it's essential to identify and address the underlying factors contributing to the condition. This may involve a combination of lifestyle changes, such as improving nutrition and increasing physical activity, as well as medical treatments such as antibiotics, antivirals, or other medications prescribed by a doctor.

eating certain foods can elevate the basal metabolic rate, and thus promote weight loss.
T/F

Answers

True.

Eating certain foods can indeed elevate the basal metabolic rate (BMR), which is the amount of energy the body needs to maintain basic bodily functions at rest. Foods that are high in protein and fiber, such as lean meats, whole grains, fruits, and vegetables, require more energy to digest and metabolize. This thermic effect of food can temporarily increase the BMR and contribute to a higher calorie burn.

However, it is important to note that the impact of food on BMR is relatively small compared to other factors such as physical activity and overall calorie intake. Sustainable weight loss is typically achieved through a combination of healthy eating, regular physical activity, and maintaining a calorie deficit. Simply eating specific foods alone is not a guaranteed solution for weight loss.

The so-called fast pathway leads from the _____ directly to the amygdala, whereas the so-called slow pathway leads from the thalamus to the _____ and then to the amygdala.

Answers

The so-called fast pathway leads from the sensory organs directly to the amygdala, whereas the so-called slow pathway leads from the thalamus to the cortex and then to the amygdala.

The amygdala is a key structure in the brain involved in processing emotions and fear, while the thalamus is responsible for relaying sensory information to the cortex for further processing. Therefore, the fast pathway allows for rapid and instinctive emotional responses, while the slow pathway allows for more nuanced and complex emotional processing.

When we experience a sensory stimulus, such as seeing a snake, there are two possible pathways that the information can travel through in the brain: the fast pathway and the slow pathway.

The fast pathway is also known as the subcortical pathway because it bypasses the cortex, which is the outer layer of the brain that is responsible for processing information. Instead, the fast pathway sends sensory information directly from the sensory organs (such as the eyes) to the amygdala, which is a small almond-shaped structure in the brain that is involved in processing emotions and the fight-or-flight response. This pathway is called the fast pathway because it allows for a quick and automatic response to potential threats, without requiring conscious thought or processing by the cortex.

The slow pathway, on the other hand, is known as the cortical pathway because it involves processing by the cortex. When sensory information enters the brain through the thalamus (which is a relay station for sensory information), it can either go directly to the amygdala through the fast pathway or it can be sent to the cortex for further processing. In the slow pathway, the sensory information is sent to the cortex, where it is analyzed and interpreted in more detail before being sent to the amygdala. This pathway takes more time, but allows for more complex and nuanced processing of sensory information.

Therefore the so-called fast pathway leads from the sensory organs directly to the amygdala, whereas the so-called slow pathway leads from the thalamus to the cortex and then to the amygdala.

To mitigate these emissions, regulatory measures such as vehicle emission standards and fuel efficiency requirements have been implemented in many countries. Additionally, the shift towards electric vehicles and alternative modes of transportation like biking and public transit can further reduce the environmental impact of transportation.

In contrast, vehicles mainly emit air pollutants such as carbon monoxide, nitrogen oxides, particulate matter, and volatile organic compounds. These emissions result from the combustion of fossil fuels like gasoline and diesel, and they can have negative impacts on air quality, human health, and the environment. While steps have been taken to reduce emissions from vehicles, such as the introduction of catalytic converters and stricter emission standards, automobiles and trucks still contribute significantly to air pollution.

homo erectus cranial bones are __________ than homo ergaster cranial bones.

Answers

Homo erectus cranial bones are larger and more robust than homo ergaster cranial bones.

Homo erectus and Homo ergaster are two closely related species of early humans that lived around 1.9 million to 600,000 years ago. These species are known for their significant adaptations and technological advancements, including the development of stone tools and the ability to control fire.

In terms of cranial bones, both Homo erectus and Homo ergaster had larger brains than their predecessors, with an average cranial capacity of around 900-1100 cubic centimeters (cc). However, there are some differences in the shape and size of their cranial bones.

Homo erectus had a long, low skull with a prominent brow ridge and a receding forehead. The skull was also thick-walled and robust, suggesting that it was adapted for heavy chewing and powerful biting. The skull also had a large occipital torus, which is a bony protrusion at the back of the skull where the neck muscles attach.

On the other hand, Homo ergaster had a more rounded skull with a less pronounced brow ridge and a more vertical forehead. The skull was also thinner and more gracile than that of Homo erectus, indicating that it was adapted for more efficient chewing and biting. The occipital torus was also less prominent than in Homo erectus.

Overall, the differences in cranial bone structure between Homo erectus and Homo ergaster reflect their evolutionary adaptations to their respective environments and lifestyles. Homo erectus lived in a variety of habitats, including open grasslands and forested areas, and likely had a diet that consisted of tough, fibrous foods such as roots and tubers. In contrast, Homo ergaster is thought to have lived primarily in open savannah environments and may have had a more varied diet that included meat from hunting and scavenging.
