The tissue that is affected during the process in which Platyhelminthes exhibit cephalization is the nervous system. <span>Cephalization is actually a process in which the nervous tissues get clustered towards the end of an organism. I hope that this answer has actually come to your help.</span>
Answer:
Organic fertilizers continue to improve the soil long after the plants have taken the nutrients they need. Therefore, the longer your soil is fed with organic fertilizers, the better its composition and texture. So, while inorganic fertilizer is cheaper in the short term, it adds less to the soil in the long term.
Answer:
The hamsters were all brown because one side gave all dominant genes.
Explanation:
In the question, it tells you that one group of hamsters all had the genotypes BB. The other group had the genotype bb. In biology, capital letters represent dominant traits and lowercase represent recessive traits. Using this knowledge, we now know that one hamster has all dominant genes, while the other had all recessive genes. In this example, we will only need to use one law of inheritance: the law of dominance. In the law of dominance, if an individual inherits two different alleles (B & b) and only one phenotype is visible (the brown of B), then that allele is dominant. That explains why the hamsters are all brown! Each hamster has one dominant allele that came from the hamster that had BB. Now, you might wonder where the Punnett Square ties into this. A Punnett square is used to track the alleles of organisms. If you draw a Punnett square, you'll be able to see that each box has Bb inside of it. This means that each hamster offspring carries one dominant and one recessive gene inside of it. While they all have a b, the dominant B gene is also there, so the hamsters are all brown. I'm sorry this is so wordy, but I hope this helps!
<h2>Calories percentage in fat</h2>
Explanation:
- The number of calories gained when eating different types of food differs. Some food types are more fattening relative to other types.
- The number of calories consumed when eating carbohydrates - 4 calories/ gram * 250 g = 1000 calories
- Calories gained eating proteins -4 calories/gram * 75 g = 300 calories
- Calories gained eating fats- 9 calories/ gram * 60 g = 540 calories
- Total amount of calories consumed = 1000 + 300 + 540 = 1840 calories
- Percentage of calories coming from fats = 540/1840 *100% = 29.3 %
- Hence, the right answer is " 29.3% of calories of her day's intake came from fat"
