Disaccharides. Disaccharides (di- = “two”) form when two monosaccharides join together via a dehydration reaction, also known as a condensation reaction or dehydration synthesis.

Answer:

The general term for carbohydrates composed of two monosaccharides is "disaccharide".

Explanation:

Disaccharides are formed by the condensation (removal of a water molecule) of two monosaccharides, and are also sometimes called "double sugars". Examples of disaccharides include sucrose (table sugar), which is made up of glucose and fructose, and lactose, which is made up of glucose and galactose.

Answer:

a) k_m = 4.08 uM

  V_{max} = 20.07 uM/min

b) k_m = 8.16 uM

Explanation:

Given that:

For Enzyme A:

the substrate concentration [S] = 40 uM

the initial velocity rate v = 10 uM/min

when it was 4mM, v = 20 uM/min

i.e.

at 4mM = 4000 uM;

Using Michealis -menten equation;

when v = 10

\(V = \dfrac{V_{max}[S]}{k_m+[S]}\)

∴

\(10 = \dfrac{V_{max}\times 40}{k_m + 40}\)

\(10 (k_m + 40) = V_{max}40\)

\(40V_{max} -10k_m = 400 --- (1)\)

when v= 20

\(20= \dfrac{V_{max}\times 4000}{k_m + 4000}\)

\(20 (k_m + 4000) = V_{max}4000\)

\(4000V_{max} -20k_m = 8000 --- (2)\)

equating equation (1) and (2):

\(40V_{max} -10k_m = 400 --- (1)\)

\(4000V_{max} -20k_m = 8000 --- (2)\)

let multiply equation (1) by 100 and equation (2) by 1

4000V_{max} - 1000K_m = 4000

4000V_{max} - 20 k_m = 8000    

  0        -980k_m = 4000

k_m = 4000/-980

k_m = 4.08 uM

replacing the value of k_m into equation (1)

40{V_max } - 10(4.08) = 400

40{V_max } - 40.8 = 400

40{V_max } = 400 +  40.8

40{V_max } = 440.8

V_{max} = 440.8/40

V_{max} = 11.02 uM/min

b)

Since V_{max} of A ie equivalent to that of B; then:

V_{max} of B = 11.02 uM/min

Here;

[S] = 80  uM

V = 10 uM/min

∴

\(10 = \dfrac{11.02 \times 80}{k_m + 80 }\)

10(k_m +80) = 881.6

10k_m = 881.6  - 800

10k_m = 81.6

k_m = 81.6/10

k_m = 8.16 uM

Cystic fibrosis is an autosomal recessive disorder.

Cystic fibrosis (CF) is an inherited genetic disorder that affects the lungs, pancreas, and other organs. It is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which is located on chromosome 7. The CFTR gene provides instructions for making a protein that regulates the movement of salt and water in and out of cells in the body. CF is inherited in an autosomal recessive pattern, which means that a person must inherit two copies of the mutated CFTR gene, one from each parent, to develop the condition. If a person inherits only one mutated CFTR gene, they are a carrier of the condition but do not have symptoms. If two carriers have a child, there is a 25% chance that the child will inherit two mutated CFTR genes and develop CF. Autosomal recessive disorders are inherited when both parents carry one copy of a mutated gene, but do not have symptoms of the disorder. In this case, there is a 25% chance that their offspring will inherit two copies of the mutated gene and develop the disorder. Since CF is inherited in an autosomal recessive pattern, it means that a child can only develop the condition if both parents are carriers or have the condition themselves.

Competition occurs among members of the same species and  between members of different species.

More broadly, competition can be described as the direct or indirect contact of organisms that results in a change in fitness when the organisms share a resource. Competition is most commonly thought of as the interaction of individuals that compete for a common resource that is in limited supply. The weaker competitors frequently suffer as a result of the outcome. The three main types of competition are as follows. Real competition is defined as two of them: interference competition and exploitation competition. Evident competition, a third form, is not. While exploitation competition and seeming competition take place between people in an indirect manner, interference competition happens between people directly.

Interactions are seen as interference competition when one person directly changes another person's resource-attaining behavior. For instance, a dominant male directly affects the mating behavior of other males when he prevents other males from approaching a partner by physical aggressiveness or aggressive displays.

According to the question intracellular digestion would indicate that an animal is more complex.

Intracellular digestion is the process by which cells break down and absorb nutrients and other molecules. This process is also known as endocytosis. Intracellular digestion occurs through a number of mechanisms, including phagocytosis, pinocytosis, and receptor-mediated endocytosis. In phagocytosis, a cell engulfs a particle or molecule, such as a virus, and then digests it within its membrane-bound vacuole. Pinocytosis involves the uptake of small particles or molecules into the cell through tiny vesicles. Receptor-mediated endocytosis is a process in which specific molecules are taken up into the cell by binding to receptors on its membrane. The molecules are then engulfed and transported into a compartment within the cell, where they are broken down by enzymes.

Explanation:

No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.

Behaviors associated with cancer(s) are Oprtion D, Both a& b. Option A, identified by Lydia Temoshok, and Option B, very, very nice people, stoic, non-emotional.

Lydia Temoshok, a researcher in psychoneuroimmunology, has identified various behavioral patterns that can be associated with cancer. However, it is important to note that these patterns are not exclusive to all individuals with cancer. Cancer affects people from all walks of life, and their behaviors can vary significantly.

Some individuals diagnosed with cancer may exhibit certain behavioral tendencies that could be categorized as "very, very nice people, stoic, and non-emotional." These individuals may approach their diagnosis and treatment with a sense of calmness, resilience, and a desire to maintain a positive outlook. They may choose to internalize their emotions and focus on staying strong for themselves and their loved ones.

On the other hand, it is crucial to recognize that cancer can also elicit a range of emotional responses in individuals, leading to behaviors that may differ from the aforementioned stereotype. Some people may experience heightened emotional states, such as fear, anxiety, sadness, or anger. They may express their emotions more openly and seek support from others. It is essential to understand that these responses are valid and normal in the face of a challenging and life-altering diagnosis.

Ultimately, cancer-related behaviors are highly individualized and cannot be generalized across all people with cancer. Each person's experience is unique, and their behaviors may be influenced by various factors such as personality, coping mechanisms, support systems, and personal circumstances. It is important to approach individuals with cancer with empathy, understanding, and an open mind, acknowledging and respecting the diversity of responses and emotions they may exhibit.

Some molecules are too large to pass through the cell membrane without the assistance of a protein channel. The process of molecules traveling along their concentration gradient through protein channels is called facilitated diffusion.

The process of spontaneous passive movement of molecules or ions across a biological membrane by particular transmembrane integral proteins is known as facilitated diffusion.

A form of passive transport is facilitated transport. In contrast to simple diffusion, where substances flow across a membrane without the aid of membrane proteins, substances diffuse across the plasma membrane with the aid of membrane proteins in assisted transport, also known as facilitated diffusion.

Facilitated diffusion is significant because it controls what enters and exits the cell. The cellular component that controls the selective transport of chemicals is the plasma membrane. Facilitated diffusion is illustrated by the movement of amino acids and glucose into cells from the circulation.
