avian influenza ha binds more tightly to 2,3-linked sialic acid. why are humans less susceptible to infection by avian influenza than they are to human adapted flu viruses?

The statement "overall; glycolysis, transition reaction, and citric acid/Krebs cycle are anabolic & endergonic; oxidative phosphorylation is catabolic exergonic" is false because glycolysis, transition reaction, and citric acid/Krebs cycle are catabolic and exergonic processes while oxidative phosphorylation is anabolic and endergonic  

Both glycolysis and oxidative phosphorylation involve the process of phosphorylation, which is the addition of a phosphate group to a molecule, but they occur in opposite directions and have different energy requirements.
Glycolysis, transition reaction, and citric acid/Krebs cycle are catabolic processes that break down molecules, and they are generally exergonic, meaning they release energy.

Oxidative phosphorylation, on the other hand, is an endergonic process that uses the energy released from these catabolic processes to synthesize ATP through the phosphorylation of ADP. Therefore, the statement "overall; glycolysis, transition reaction, and citric acid/Krebs cycle are anabolic & endergonic; oxidative phosphorylation is catabolic exergonic" is false.

These are the 9 main life processes of an animal and how hydra accomplish each of them:

Respiration: Hydras respire through their skin. The skin is thin and allows oxygen to diffuse into the body. Carbon dioxide diffuses out of the body in the same way.

Nutrition: Hydras are carnivores and feed on small animals, such as plankton and insects. They capture their prey with their tentacles and inject it with a paralyzing venom. The venom paralyzes the prey and makes it easier for the hydra to digest.

Excretion: Hydras excrete waste products through their skin. The waste products diffuse out of the body in the same way that oxygen diffuses in.

Sensitivity: Hydras are sensitive to touch, light, and chemicals. They use these senses to find food, avoid predators, and reproduce.

Movement: Hydras can move by contracting their body. They can also move by extending their tentacles.

Growth: Hydras grow by cell division. The cells at the tip of the body divide and create new cells. These new cells are added to the body of the hydra, making it grow longer.

Reproduction: Hydras can reproduce sexually or asexually. Sexual reproduction involves the fusion of two gametes, each from a different hydra. Asexual reproduction involves the budding of a new hydra from the body of an existing hydra.

Development: Hydras develop from a fertilized egg. The egg divides into two cells, then four cells, and so on. The cells eventually form a blastula, which is a ball of cells. The blastula then forms a gastrula, which is a cup-shaped organism with two layers of cells. The gastrula eventually develops into a hydra.

Death: Hydras can die from a variety of causes, including starvation, predation, and disease.

The most significant predictor of childhood obesity is maternal obesity.

Numerous studies have shown that maternal obesity is strongly associated with an increased risk of childhood obesity. Maternal obesity during pregnancy can have long-lasting effects on the developing fetus, including alterations in metabolism, hormonal imbalances, and changes in the developing brain.

These factors can contribute to an increased susceptibility to obesity in childhood and later in life.

Maternal obesity can influence the intrauterine environment, leading to an overexposure of the fetus to excessive nutrients and adipokines, such as leptin, insulin, and inflammatory cytokines. This can disrupt the normal development of metabolic pathways and regulatory mechanisms involved in energy balance and body weight regulation.

Additionally, maternal obesity can also impact early feeding practices, such as breastfeeding initiation and duration, as well as the introduction of solid foods. These factors can further contribute to the development of unhealthy eating habits and an increased risk of childhood obesity.

It is important to address maternal obesity as part of comprehensive strategies to prevent and manage childhood obesity. This may include interventions targeting preconception and prenatal care, promoting healthy lifestyles and weight management, and providing support for breastfeeding and healthy infant feeding practices.

The answer to the given question is as follows: When both the sternocleidomastoid muscles contract, the head turns towards the opposite side.

The answer to the given question is as follows: When both the sternocleidomastoid muscles contract, the head turns towards the opposite side. These muscles are the pair of large muscles that run from the back of the ears to the clavicle (collarbone) and sternum (breastbone). They act as flexors of the neck and help with the rotation of the head. When the sternocleidomastoid muscles contract together, they can cause the head to flex forward or bow down, depending on the degree of contraction. In addition to rotation and flexion, the sternocleidomastoid muscles are also involved in side bending of the neck. The muscles are innervated by the accessory nerve and are essential for maintaining good posture. Dysfunction of the sternocleidomastoid muscles can lead to a variety of problems, including headaches, neck pain, and restricted range of motion in the neck. Hence, the contraction of the sternocleidomastoid muscles plays an important role in controlling the movement of the head and neck.

In Exercise 11.10, the expected value of the number of butterflies found by Alice, Bob, and Charlotte is obtained by finding the expected value of the sum of three indicator random variables.

In Exercise 11.16, the expected value of the number of flips needed to get the second head in a coin flipping experiment is determined. These exercises involve different scenarios of sampling with and without replacement.

In Exercise 11.10, the expected value of X, the total number of butterflies found, is found by calculating the expected value of each indicator random variable (X1, X2, X3) representing whether Alice, Bob, and Charlotte found a butterfly, respectively.

The expected value of each indicator variable can be obtained by multiplying the probability of success (finding a butterfly) by 1 and the probability of failure (not finding a butterfly) by 0. Then, the expected value of X is calculated as the sum of the expected values of the indicator variables.

In Exercise 11.16, the expected value of X, the number of flips needed to get the second head, is determined. To find this value, we first need to find the expected value of getting the first head. This scenario is similar to Example 11.11, which involves sampling with replacement.

Each coin flip is an independent event, and the probability of getting a head is constant at 0.5.

Therefore, the expected value of getting the first head is 1/p, where p is the probability of success (0.5 in this case).

In Exercise 11.17 (a), the scenario of waiting for a favorite song in Michael's iTunes playlist involves sampling without replacement. Each song played is not replayed, and there is only one favorite song among the total number of songs.

Therefore, this scenario is similar to Example 11.10, sampling without replacement.

To find the expected number of songs Michael needs to listen to until his favorite song comes up, the formula for sampling without replacement is used, which is the reciprocal of the probability of selecting the favorite song at each step.

The given statement "symphyses are synarthrotic joints that are designed for strength with flexibility" is true. They provide stability and support to the body, while also allowing for some degree of movement and flexibility.

Symphyses are specialized cartilaginous joints that connect two bones together. They are found primarily in the midline of the body, such as in the pubic symphysis, the joint that connects the two pubic bones in the pelvic girdle, and in the intervertebral discs of the spinal column.

The strength of symphyses comes from the fibrocartilaginous material that forms the joint. This material is strong and flexible, allowing the bones to move slightly while still maintaining their connection.

This flexibility is important for absorbing shocks and forces that are transmitted through the body, such as during walking, jumping, and other physical activities.

Symphyses also provide a degree of stability to the body, as they help to distribute the weight of the body evenly across the bones. This is important for maintaining balance and preventing injuries
