Yes, they do. Many plants will have seed pods (like dandelions) that fly away or drop off. This helps distribute the seeds and promotes more plants being grown elsewhere. Another adaptation would be having their seeds inside fruits. This causes other animals to eat it and distribute the seeds that way in their waste.

Rotenone is a poison commonly added to insecticides. Rotenone binds tightly with one of the electron carrier molecules in the el
Scorpion4ik [409]

Answer:

True.

Explanation:

Rotenone is a broad spectrum pesticide and insecticide and is also considered as a non-selective piscicide.

The action mechanism of the rotenone has been described below -

It interferes with the electron transport chain which occurs in mitochondria of the cells. Here the transfer of electrons from complex I to the ubiquinone is inhibited by the rotenone. As a result, ATP formation with the help of NADH is also inhibited. When electron transport fails, oxygen in the cell is reduced to oxygen radical which further damages DNA and other components present in the mitochondria.

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

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.

Which of the following terms describes how a neuronal membrane's potential is altered in the presence of inhibitory signals? Vie
pogonyaev

Answer:

Hyperpolarization

Explanation:

When the membrane potential becomes more negative than the resting potential, the membrane is hyperpolarized. Hyperpolarization is inhibitory in nature and decreases the ability of the neuron to generate a neural impulse. During signal transmission at a chemical synapse, binding of neurotransmitters to the receptors stimulates the opening of ligand-gated ion channels. The flow of ions changes the voltage across the membrane and may cause depolarization or hyperpolarization. For instance, the opening of Cl– or K+ channels causes hyperpolarization.
