Answer:

3) they lose energy at a varying rate - is the correct answer.

Radioactive decay is defined as the process by which an unstable atomic nucleus loses its energy by emitting radiations. The decay is random and cannot be predicted earlier.

Answer:

1)  They release energy.

Explanation:

The radioactive decay of chemical elements is a phenomenon in which the unstable nucleus of an atom disintegrates becoming a more stable nucleus, but due to the decay, particles such as alpha and beta particles among others are released.

A Radioactive decays releases energy (it is important to remember that energy is not created or destroyed, only transformed), in order to move from a non-stable nucleus to a more stable one.

The radioactive decay has an exponential decay, which means that it is reduced steadily over time, and this depends on the element.

The statemente that best describes what happens to elements during radioactive decay is: 1)  They release energy.

Which areas of the brain undergo major growth spurts during middle childhood?
djverab [1.8K]

sensory and motor areas undergo major growth spurts during middle childhood.

  • The two types of motor (movement) skills that children acquire are called "fine motor skills" and "gross motor skills."
  • Using hands and fingers to control smaller things is a function of fine motor abilities. coordination is a component of gross motor skills.
  • Synaptic remodeling, or pruning, is a natural process of maturation. Additionally, because each child has a different experience, the brain grows in large part as a result.
  • More often utilized synapses tend to be kept, whereas less frequently used synapses are lost.
  • The brain is driven by the motor system, which also drives sensory stimulation and feedback.
  • These abilities must advance and grow in order to support behavior and academic learning.
  • Children that struggle academically or behaviorally frequently have underdeveloped sensory and motor systems.

Yeasts are unicellular microorganisms of the fungi kingdom that can digest sugars using both aerobic and anaerobic cellular resp
tiny-mole [99]

Answer:

This question is incomplete as it does not contain the representation of the experiment, however, based on general understanding, the answer is:

Carbon dioxide (CO2)

Explanation:

Yeasts, as stated in this question, are living unicellular organisms that belong to the KINGDOM FUNGI. They employ both the aerobic (with oxygen) and anaerobic respiration (without oxygen) in breaking down sugars. However, both methods of cellular respiration gives off CARBON DIOXIDE (CO2) as a byproduct.

Therefore, when a yeast is placed in a balloon in accordance to this experiment and is allowed to perform respiration either aerobically or anaerobically, it gives off CO2 gas, which causes the balloon to expand.

Determine the probability of producing light colored moths if a heterozygous dark male is crossed with a light female moth
Virty [35]

Answer:

1/2 or 50%

Explanation:

Let us assume that the existence of heterozygous dark male means that the dark trait is dominant over the light trait. Hence, the light color trait is recessive.

Let us also assume that the dark color trait is represented by the allele A and the light color trait by allele a.

Heterozygous dark male = Aa

Light female = aa

Crossing the two:

            Aa    x    aa

         Aa   Aa   aa   aa

Aa = dark color = 1/2 or 50%

aa = light color = 1/2 or 50%

<em>Hence, the probability of producing light-colored moths would be </em><em>1/2 </em><em>or </em><em>50%.</em>
