Answer:

C. Removing this step decreases the amount of carbon in the air: This is correct, removing factories would decrease the emission of greenhouse gases, thus decreasing CO2 in the atmosphere.

Explanation:

When we look at the picture we can see that the line that goes from G to C, goes from a factory to the atmosphere. As we know factories release a great number of elements into the atmosphere being one of them, carbon dioxide. Therefore taking into consideration we can proceed to analyze the following statements.

A. Removing this step prevents photosynthesis in the next step: This is not true industry increases carbon dioxide in the atmosphere, even if they don't exist there is enough CO2 for plants to perform photosynthesis.

B.Removing this step increases the amount of carbon in the soil: This is not true as factories release carbon dioxide to the atmosphere, not the soil.

C. Removing this step decreases the amount of carbon in the air: This is correct, removing factories would decrease the emission of greenhouse gases, thus decreasing CO2 in the atmosphere.

D. Removing this step increases carbon storage in plants: This is incorrect the carbon storage in plants is cording to their necessities independently of the abundance in CO2, in the atmosphere.

One of the traits that we looked at in class was a widow's peak (has peak is dominant, no peak is recessive). For each individua
Marina CMI [18]

Answer:

Explanation: 1) Individual who is bald but neither parents has a widow's peak: As having a peak is dominant and the individual is bald with parents that doesn't have the trait, the genotype is recessive, in the case ww;

2) Individual has a widow's peak: The individual's genotype can be WW, homozygous for the trait or Ww, heterozygous for the trait, depending on the genotype of the parents;

3) Individual can't roll their tongue: Being able to roll the tongue is a dominant characteristics, so if the individual can't roll their tongue means the genotype is recessive. But, there is little evidence that this trait is dominant or inheritable;

4) Individual has a widow's peak  but their mother does not: In this case, the genotype of the individual is heterozygous (Ww), because the mother is recessive (ww) and the offspring has the trait, so the father must have had it;

5) If an individual does not have a widow's peak (ww), which genotype would be impossible? If this individual crosses over with another individual with the same trait, their children will be all recessive for widow's peak (ww), so there is no possibility of an offspring with the trait;

If the initial individual crosses over with an individual with widow's peak, two possiblities can occur:

  • If the crossover is with an individual homozygous for the trait (WW): all their children will have widow's peak with genotype Ww. So, the possibility of not having the peak is 0;
  • If the crossover is with an individual heterozygous for the trait (Ww), there will be a probability of 25% for the children to have genotype WW, a probability of 50% for the offspring to be heterozygous (Ww) and has the trait and probability of 25% to be recessive (ww) and therefore doesn't have the trait;

Fructose is? also known as dextrose. the sweetest of the sugars. abundant in whole grains. a starch. known as milk sugar.
Elina [12.6K]

Dextrose and fructose are both types of sugar. the sugar with the best flavor. plenty of whole grains. the starch. called milk sugar.

It is also found naturally in other plant foods such as honey, sugar beets, sugar cane, and vegetables.  Fructose is the  sweetest naturally occurring carbohydrate, 1.2 to 1.8 times more  sweeter than sucrose (table sugar). is the sweetness of Fructose metabolism does not require insulin and has little effect on blood sugar levels.  There are many different types of sugar, some  more common than others. Fructose, like glucose, is a type of sugar known as a simple sugar or "simple sugar". Monosaccharides can be combined to form disaccharides, the most common of which is sucrose, or "sugar." Sucrose is made up of 50% fructose and 50% glucose. Fructose and glucose have the same chemical formula (C6H12O6), but due to their different molecular structures,  fructose is 1.2 to 1.8 times sweeter than sucrose. In fact, fructose is the sweetest natural carbohydrate.

In nature, fructose is most commonly found as a component of sucrose. Fructose is also found in plants as a simple sugar, but that doesn't mean other sugars don't exist.

Phasic receptors adapt quickly to a stimulus. For that reason, they are good at detecting changes instead of constantly signalin
Ainat [17]

Answer:

TRUE

Explanation:

Phasic receptors are sensory receptors that are fast acting in detecting changes in the strength of a particular stimulus or signal to the brain. They are  fast adapting receptor cells that detect changes in the strength of a stimulus. Because of this fast adapting ability, they cannot be used by the CNS in constant signalling of stimulus. A different receptor called Tonic receptors are used by the brain for constant signalling because they are slow reacting cells are they continue to transmit signals to the CNS along as the stimulus remains and not to changes in the pressure or strength of the stimulus. Phasic receptors are so important in predicting the changes in the body fora given time and this helps to quantify how body can react to increase or release of a stimulus. because when  stimulus is added it signals the brain for some time and it signals stops but when the stimulus is released, it also signals the brain detecting bodily deformations to various stimulus.
