How can interactions between alleles genes and the environment affect an organism's traits?
Nataly_w [17]
Genes code for proteins. That way they determine biological structures and functions. Besides genes, the environment has the great impact on the structure of an organism. Alleles and genes will give a trait, but the environment can affect it. For example, alleles that are responsible for height will give a person some average height. But if the person begins to train basketball at the early age (during growth), the person will overcome the average height. This is the effect of the environment and not genes. The other example is that if a person lives in a sunny region, the person will be tan.

An extracorporeal liver assist device was surgically implanted into sam. this device is very similar to
musickatia [10]

An extracorporeal liver device is similar to a kidney dialysis because this is the device used for liver dialysis.

Liver dialysis or technically known as Single-Pass Albumin Dialysis is designed to remove protein-bound toxins. It is the simplest form of albumin dialysis which utilizes the rudimentary principles of hemodialysis or hemodiafiltration. The dynamics of this procedure begins with the patient's blood flowing through a standard high-flux dialyzer that is impermeable to albumin. This is then dialyzed against a dialysate with an albumin concentration of 2%-5%, which is discarded after a single pass. It allows the removal of albumin-bound molecules that are minute enough to pass through the porous membrane and as well as water-soluble toxins.

The heating curve of an ice-water mixture that is slowly heated to 125°C contains three sloped and two level portions. What do t
scZoUnD [109]
The 2 level portion in the graph represents the changing of state.

Every substance has internal energy, which includes kinetic energy and potential energy. Kinetic energy means the temperature, and the potential energy means the bondings or attractions.

When a substance is heated up, they first increase their temperature as the same state. For example, the ice starts at - 5 °C, they won't start melting immediately as they're not at their melting point yet. Instead, they first absorb heat and increase their temperature to 0°C. This is same for when water increase their temperature until their boiling point. Their kinetic energy is increasing, but potential energy is unchanged as they stay at the same state. That's why the slope is increasing.

However, but once the ice or water has reached their melting or boiling point, they have to go through a state change. During that time, they do not increase their temperature (K.E. unchanged) . Instead, the heat they absorbed is used to increase the potential energy to break the bonds and turn into another state. The heat absorbed is called latent heat.

This explains why in the graph, there's 2 level portions, as the substance is going through a state change and increasing their potential energy instead of their kinetic energy (temperature)

What component of the circulatory system is at the tissue level? a. blood b. white blood cell c. heart d. hemoglobin
nata0808 [166]

Answer;

A. Blood

Explanation;

The main organs of the Circulatory system are the heart, the brain, the lungs. There are other key things like arteries, veins, and capillaries but they are not organs.

The major tissues in the circulatory system are the epithelial, muscle, nervous, and connective tissues.

Blood is the main connective tissue in the circulatory system, but it's a liquid connective tissue. Blood tissue is in the same family as bone and cartilage, but instead it has a liquid medium that holds it together.
