I believe there are three correct answers from the choices listed above. The statements that describe an element are as follows:

<span>An element is a pure substance that cannot be broken down into a simpler form.
</span><span>All elements are listed on the periodic table of elements.
An element symbol begins with a capital letter; if there is a second or even third letter, it is a lowercase letter.</span>

natali 33 [55]

Answer:

relies on the evaluation of dreams and the unconscious desires.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

This ultimately implies that, the manner in which living organism such as humans look and behave is largely dependent on both the traits inherited from their parents and the environment in which they grew up or stayed.

Hence, the behavioral genetics approach relies on the evaluation of dreams, unconscious desires, twin, family, and adoption studies which are used to investigate the gene possessed by living organisms or their environment interactions.

In the complete oxidation of glucose, six CO2 molecules are formed per glucose molecule. The number of CO2 molecules released by
Serga [27]

Answer:

0, 2, 4

Explanation:

The process of cellular respiration takes place in for phases which oxidizes the glucose molecule to the provide energy molecule called ATP.

Along with ATP, the process releases the metabolic water and carbon dioxide gas. In the oxidation of one glucose molecules, about 6 molecules of CO₂ are released. These CO₂ molecules are produced in the following manner:

1. Glycolysis: CO₂ gas is not produced during this reaction but only ATP and NADH are produced.

2. Pyruvate decarboxylation: the process converts the pyruvate produced by glycolysis to Acetyl-CoA. Formation of 1 Acetyl-CoA produces 1 CO₂ and since 2 Acetyl-CoA is produced therefore produces 2 CO₂ molecules.

3. Citric acid cycle: The cycle converts 2 Acetyl-CoA and produces 4 CO₂ in two cycles converting each Acetyl-CoA.

Thus, 0, 2, 4 is correct.

Tratando-se sobre atividades aeróbias, segundo Cooper (1972), qual das alternativas abaixo não está correta? a) Aumento da efici
olya-2409 [2.1K]

Answer:

Diminuição do colesterol bom (HDL), aumento do colesterol mal (LDL)

Explanation.

Esto debe revertirse, debe ser una disminución del colesterol malo y un aumento del colesterol bueno.

Básicamente, el ejercicio aumenta el HDL y reduce los triglicéridos. En condiciones normales, los ejercicios aeróbicos no reducen el LDL. Sin embargo, cuando se combina con cambios en la dieta y una pérdida de peso bien controlada, el efecto combinado podría reducir el LDL.

En las condiciones estándar, el ejercicio recomendado por semana es de 150 minutos de ejercicios suaves o 75 minutos de ejercicio vigoroso por semana.

Por lo tanto, cuando se calcula por semana, esto sería un promedio de 20 minutos de ejercicio por día.

Andar en bicicleta, caminar, hacer jardinería y aeróbicos acuáticos son ejemplos prácticos de ejercicios leves o moderados que podrían aumentar el HDL. Sin embargo, el baile aeróbico, el trote y el salto de cuerda son ejemplos de ejercicios vigorosos que, cuando se combinan con la dieta y la pérdida de peso, conducen a una disminución del LDL.

This should be reversed, it should be a decrease in bad cholesterol and an increase in good cholesterol.

Basically, exercise boosts the  HDL and lower triglycerides. Under normal conditions, Aerobic exercises do not reduce LDL. However, when combined with dietary changes and well-monitored weight loss the combined effect could lower LDL.

Under the standard conditions, the recommended exercise per week is 150 minutes of mild exercises or 75 minutes of vigorous exercise per week.

Therefore, when calculated per week this would be an average of  20 minutes of exercise per day.

Biking, walking, Gardening, and water aerobic are practical examples of mild or moderate exercises that could boost HDL. However, Aerobic dancing, jogging, and rope jumping are examples of vigorous exercises which when combined with dieting and weight losses leads to a lowering of LDL.
