Explanation:

El dolor en la articulación metatarsofalángica se debe a cambios tisulares debidos a una biomecánica aberrante del pie. Los signos y síntomas incluyen dolor al caminar y dolor a la presión. El diagnóstico es clínico; sin embargo, deben realizarse estudios para excluir infecciones o enfermedades reumáticas sistémicas (como la artritis reumatoidea). El tratamiento incluye ortesis, a veces inyección local, y en ocasiones cirugía.

The femur is a typical example of a long bone. Describe the structure of the femur diaphysis and the epiphyseal ends. Explain wh

dimaraw [331]

<u>Answer</u>:

Femur diaphysis and epiphyseal ends is made up with cortical bone and contains bone narrow. It is in the middle tabular part and composed with compact bone and central marrow cavity is situated around it. It is round in shape and a long bone. It is the origin of the attachment of many muscles as well as ligament.

The femur is the longest bone which is present in our thigh and also call as thigh bone. The division of femur can be divided into shaft, proximal and distal. In some aspect it is the strongest bone of our body and it helps in any activities.

Glycolysis is the first step of cellular respiration, in which glucose is used to generate ATP to power the cell. The major chem

lutik1710 [3]

Answer:

The correct answer is b. C6H12O6 -> 2 C3H4O3+2 H+

Explanation:

Glycolysis occurs in both the condition aerobic and anaerobic so it does not require oxygen. In glycolysis, one glucose molecule is converted into two pyruvate( 2 C3H4O3) and two 2 ATP, 2NADH, and 2 H₂O are produced.

Initially, 2NAD⁺ is produced during glycolysis which is reduced to produce 2NADH and 2 H⁺. Therefore the correct equation is C6H12O6 -> 2 C3H4O3+2 H+.

Then this pyruvate is used in the Kreb cycle which is required for the complete breakdown of glucose into carbon dioxide and water and this process occurs in aerobic conditions. Complete oxidation is important to produce more energy from partially oxidized glucose.

How many grams of the compound in the figure above are required to make 1 liter of a 0.5 M solution? (Note: The atomic masses, i

Dafna1 [17]

Answer:

This question is incomplete as there is no figure in the question but the compound in the figure is Ethanoic acid (CH3COOH). Hence, we can calculate the mass.

The answer is: 30grams

Explanation:

According to the question, the volume of the compound (CH3COOH) is 1litre while the molar concentration is 0.5M

Molarity or Molar concentration is calculated using the formula:

M= n/V

Where; M= Molarity (M) = 0.5M

n= number of moles (mol)

V= Volume (V) = 1L

Hence, number of moles (n) = M × V

n = 0.5 × 1

n = 0.5 moles.

To calculate the mass in grams of CH3COOH, we say;

Number of moles (n) × molar mass (MM)

Since atomic mass for (C= 12, H= 1 and O=16)

Molar mass of CH3COOH:

= 12 + 1(3) + 12 + 16 + 16 + 1

Molar mass of CH3COOH = 60g/mol

Mass (in grams) of CH3COOH = 0.5 moles × 60g/mol

Mass = 30grams.

Therefore, 30grams of CH3COOH compound are required to make 1 liter of a 0.5 M solution.
