Which of the following is NOT an accessory gland of the male reproductive system?

Answer:

Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules, a total of four ATP molecules, and two molecules of NADH.

Explanation:

Answer:

1 glucose molecule

2 pyruvic acid molecules

Explanation:

Glycolysis starts with 1 glucose molecule, which undergoes 4 stages until it splits into 2 pyruvic acid molecules. The products of this biochemical pathway include 2 NADH and 2 ATP molecules

Answer:

1)Protein is composed of amino acid.

We can identify protein by sequencing amino acids in peptide.

Carbohydrates is primarily avilabke energy source.

2) Proteins and nucleic acids are made up of C H O But carbohydrates and lipids consist of C H O N.

3)Nucleic acid DNA and RNA store and transmit genetic information from one generation to next generation.

Nucleic acid as present in body therefore not considered as essential nutrients.So dietary sources are plant and animal foods like meat fish vegetables etc.

Answer: Kidneys

Explanation:

a)

Actual diameter = 0.007 mm

Diameter of scaled diagram = 2.3 cm = 23 mm

Formula to use:

Magnification = scaled dimension/actual dimension

Magnification = 23/0.007

Magnification = 3285.714... → x3286

b)

Red blood cells (RBCs), otherwise known as erythrocytes, don't have nuclei and organelles such as mitochondria, are smaller than WBCs and have a biconcave disc shape ideal for purpose

c)

i.

RBCs transport oxygen inhaled into the lungs around the body to all tissues and organs

ii.

RBCs are void of organelles so they are maximally packed with haemoglobin to bind and transport oxygen;

The biconcave disc shape is ideal for flowing through the blood vessels, particularly the capillaries, optimising them for transporting oxygen;

The small size also helps in being able to circulate the vasculature effectively and successfully

iodine test

We can test for starch with the help of an iodine test. Soak any food items, namely potato, in drops of iodine for some time. If it turns blue-black afterwards, it contains starch. The liquid used for testing starch is an iodine solution.

The outcome differs in the way that the protein folds itself at each level. The changes in the way that it folds lead to:

modifications in the function, shape or in the combination with other proteins.

Protein has different levels of structure. Each of them is related to how the amino acids and other molecules interact with each other. Hair is made of proteins, so if one of the structures is affected, the hair is too.

Let's analyse what happens in each level of structure:

In conclusion, the modification of the secondary structure changes the interaction between the elements of the protein giving hair with different shapes.

Explanation:

The optimal ranges for the formation of oxygen bubbles vary between each plant, however, only water, c02, and temperature are limiting factors for photosynthesis.

This question is based on observations made during the course of an experiment designed to measure the optimal ranges at which oxygen bubbles form, given that these are an indication of photosynthesis.

Due to this, the information given will be generalized. Firstly, there is no exact optimal range of light for the formation of oxygen bubbles (photosynthesis) given that this is not a limiting factor.

Excess of light will have no effect on photosynthesis, only the lack of light can cause negative effects, therefore any light past the minimum threshold is fine.

On the other hand, water, light, and C02 are in fact limiting factors and have optimal ranges. For water, this optimal range varies greatly and therefore I cannot offer a general value, but an excess of water will "drown" plants by not allowing the formation of air pockets in the soil.

C02 sits at an optimal range of 1,000-1,300ppm for the best results. Lower concentrations cause a lower rate of photosynthesis given that it is the primary substrate for the process to begin. At too high levels, plants will have to adapt which can slow the process.

Finally, temperature is also a limiting factor for photosynthesis. Its exact value cannot be given since it varies greatly between plant species.

However, in general, terms, since it is an enzyme-dependent reaction, we can apply the general temperature at which enzymes function best which is around 37 degrees.

Answer:

A movement of a body part away from the midline, either of the body as a whole or that of the hand or foot, is termed abduction (L., to carry away). A movement of the body part back toward the midline (i.e., to the anatomical position) is known as adduction.

Explanation:

Mark me brainly please.

Abduction is a movement away from the body's midline. Abduction is the term for a bodily part's lateral movement away from the body's midline.

Thus, body parts are divided or spread apart in this process. Abduction of the arms, for instance, occurs when you raise your arms from a resting posture and spread them out to the sides. Similar to this, you are practicing leg abduction when you stretch your legs apart.

Adduction, or the movement in the direction of the midline, is the reverse of this action. Important terminology like abduction and adduction are used to describe movement in respect to the body's midline in anatomical and physiological descriptions.
