A dam is built across a river to generate electricity. What is likely effect of the construction of a dam on the river?
a)increase in the size of fish in the river
b)increase in the water flow in the river
c)decrease in the population of aquatic organisms in the river
d)decrease in the amount of pollutants dumped into the river
Answer:
c i think
Explanation:
Most likely the effect of the construction of a dam on the river is that it decreases the population of aquatic organisms in the river. Thus, the correct option is C.
What is Population?A Population may be defined as the group of individuals significantly belonging to the same species living in the same area in a definite time period.
When a dam is built across a river in order to generate electricity, it results in the reduction of the population of aquatic organisms in the river.
This is because the whole construction affects the natural habitat of aquatic organisms as well as their adaptations. So, such populations are frightened due to external construction and do not play their essential roles.
Therefore, most likely the effect of the construction of a dam on the river is that it decreases the population of aquatic organisms in the river. Thus, the correct option is C.

6. What happens to our body when we skip a meal?
Group of answer choices
Heart rate increases
We always eat a large meal when we can
Metabolism slows down
We lose weight
7.
Answer:
Bioelectrical impedance
Answer:
1. Body mass index. Reasoning: Body Mass Index is a measure of body fat based on your height and weight. Physicians widely consider BMI measurements as a simple way to determine if a person is healthy or unhealthy, underweight or overweight.
2. Tissues that contain large amounts of fluid and electrolytes, such as blood, have high conductivity, but fat and bone slow the signal down.
3. When energy expenditure exceeds energy intake, energy balance is negative and leads to weight loss. When intake equals expenditure, equilibrium results and body fat is maintained, regardless of whether the body weight is at, above, or below normal.
4. Energy balance can be maintained by regulating energy intake (through the diet), energy expenditure (adjusting physical activity level to match intake) or a combination of both.
5. Jogging or running, Weight training, Swimming, Yoga.
6. Skipping meals: Causes the body to lower its metabolism (how much energy it needs to function) Causes us to burn less energy (fewer calories) Can lead us to gain weight when we eat our usual amount of food Leaves us with little energy because the body has run out of the fuel we get from food Leaves us sluggish.

The transcript of the gene that creates the protein is known as messenger RNA (mRNA). The transcription of the DNA sequence results in the production of mRNA.
What is the funda of the DNA sequence and the mRNA sequence ?The DNA sequence and the mRNA sequence are complementary, which means that the mRNA sequence is the DNA sequence's reverse complement. The nucleotides are organised in the 5'-3' orientation in the provided DNA sequence. The nucleotides must be read in the 3'–5' orientation in order to get the mRNA sequence.
As a result, the mRNA sequence is AGACTGCCATGAAGTT. Because the mRNA sequence is composed of the DNA sequence's complementary nucleotides, it is the reverse complement of the DNA sequence.
For instance, the DNA sequence's first nucleotide, T, and its complementary nucleotide, A, which is the This is the mRNA sequence's first nucleotide. The second nucleotide of the DNA sequence is A, while the second nucleotide of the mRNA sequence is U, which is complementary to A. The sequence is consistent with this pattern.

John wants to investigate the effect of temperature on dissolving sugar in water. What will be his dependent variable? A) temperature of the water B) volume of the solvent C) time taken for sugar to dissolve
Answer: The correct option is A.
Temperature of the water
Explanation:
This is because dependent variable is variable that cannot stand alone but depends on another. It is the effect in an experiment. It is what that is been measured or tested in an experiment. Temperature if the water is dependent variable because it's what is been tested or measured in that experiment. It depend on other variables.
A rabbit is born with brown(g) fur. It has 9 other siblings from the same
litter, and they all have white(G) fur.
Select the True Statements.
• Brown fur is caused by a mutation
•The dominant allele is G
•The dominant allele is g
•gG is a genotype for white fur
•Brown fur is the recessive trait
•Gg is a genotype for brown fur
•The recessive allele is g
•White fur is dominant over brown fur
Answer and Explanation:
What we know:
1 rabbit born with brown fur (g).
9 other siblings with white fur (G).
The correct answers:
- The dominant allele is G
This is because G is capitalized, and there are more white bunnies than brown.- Brown fur is the recessive trait
We see that (g) isn't capitalized for the brown bunny, and that there was only 1 brown bunny out of the 10 bunnies in total. So, brown fur is a recessive trait.- The recessive allele is g
This is correct because g isn't capitalized, and acts recessive, or doesn't appear unless the genotype is gg, in which the recessive trait will then appear/unhide.- White fur is dominant over brown fur
There is more white fur bunnies than brown fur bunnies, so the white fur trait is dominating the brown fur trait.I hope this helps!

What was the genetic variation of dark moths and how did it occur?
Answer:
Natural Selection
Explanation:
A random genetic mutation gave rise to the dark colored moths. All types of living things have small differences between the individuals in the species. If one of those differences allows the individual to live longer, they will likely have more offspring. As that trait is passed on, the population starts to look more like a successful individual. Over time, the species changes.
