Answer:
Chick with in the egg depend for all its energy and food requirement on the egg yolk , therefore egg yolk is rich in fat, protein, and cholesterol.
Explanation:
Before the egg breaks and the chick comes out, few days nourishment for chicks is required. Hence, the egg yolk needs to be nutritious as new developing chick (with in the egg) rely for essential nutrients (required for growth) on the egg yolk. Chick require energy from yolk, hence it is rich in fat (energy). It also needs to grow and develop, therefore egg yolk has lot of protein (building blocks). Lipid and cell with in the yolk help in formation of cell and strengthening of bones and feathers
Answer: The correct answer is option c.
Explanation:
Cardiac conduction system is formed by specialized cardiac muscle cells which enable the heart to contract in coordinated fashion.
The main component of this system are:
- Sinoatrial node
- Atrioventricular node
- Bundle of His
- Branched bundle
- Punkinje fibers
SA node consists of cells known as pacemaker cells. These cells spontaneously generate action potentials which lead to the contraction of atria.
These potentials are then passed to AV node which relay them to bundle of His. These bundles are branched into right and left bundle which ultimately transfer these potentials to Purkinje fibers.
The potentials from these fibers lead to the contraction of ventricles.
Answer:
1. Picky eating; food jag
2. epiphyseal plates
3. bone mineral density (BMD)
4. obesity
5. food insecurity
6. life expectancy
7. arthritis
8. congregate meal
Explanation:
Picky eating is a behavior in early childhood when they refuse to eat certain foods and only want the same foods, while food jag is when a child only eats a small group of foods, meal after meal. The epiphyseal plate is a specialized layer of hyaline cartilage where chondrocytes (i.e., the only cells found in healthy cartilage) proliferate and differentiate during longitudinal bone growth. Arthritis is an inflammation of the joints caused by different reasons (e.g., injury, genetic causes, infections, immune system dysfunction, etc), whose risk increases with age. Bone mineral density (also known as bone density), is the amount of mineral in bone tissues, being the best manner to measure bone health. Obesity can be defined as an excessive amount of body fat that presents a risk to health. Over the past 30 years, the prevalence of obesity has doubled in children and tripled in adolescents, representing a serious health problem (especially in developed countries). Moreover, food insecurity is a social condition of limited access to food for individuals in a household to live an active, healthy life, which can be used as a metric of how many people cannot afford food. Life expectancy is an estimation of the number of years a person can expect to live in a given country/region. Life expectancy around the world has increased for nearly 200 years especially due to medical progress and access to food. Finally, a congregate meal refers to a healthy meal provided to anyone age 60 or over that encourages older adults' social connections with other persons at the meal sites.
Answer:
There are three main types of freshwater biomes: ponds and lakes, streams and rivers, and wetlands. We'll go into the details of each below. Ponds and lakes are often called lentic ecosystems. This means that they have still or standing waters, not moving like rivers or streams.
Explanation:
In this vague question, the answer is a psychological process.
In person 3, the individual undergoes a traumatic fragment of events that leads to a blind conclusive happenings in the matter of the person. Here, you'll observe that the behavior the individual is eliciting is an arising wariness of different warning signs to seek therapy.
