The correct answer is B. They control and direct the quantity of food passing through the digestive organs and prevent backward movement of partially digested food.
Explanation:
In biology, sphincters are a type of muscle that can regulate the passage of substances. In the digestive system, sphincters can be found mainly in the upper and lower zone of the stomach, between the small and large intestine and at the anus. In all cases, the sphincters regulate the amount of digested food or other substances that pass through the organs and also prevents the substances that have already passed to a new organ or zone of the digestive system can go backward.
Due to this sphincters are essential for regulating the movement of food and other substances to be correctly digested and to pass through different organs. According to this, the key function of these muscles is "control and direct the quantity of food passing through the digestive organs and prevent backward movement of partially digested food".
Part B: Create an equation that shows the amount of wages earned, S, for working y hours of overtime. Hint: Remember to include in the equation the amount earned from working 40 hours.
Part C: Lana earned $368 in 1 week. How many hours (regular plus overtime) did she work?

Answer: Both combinations result in heterozygous dominant offspring, meaning the offspring will have a combination of red and white color. Therefore, the correct answer is c) Red and white cows (heterozygous dominant).
Explanation:
When a red cow (homozygous dominant) is crossed with a white cow (homozygous dominant), the offspring will inherit one allele from each parent. In this case, the red cow has two copies of the dominant allele for red color (RR), and the white cow also has two copies of the dominant allele for white color (WW).
The dominant allele for red color (R) is represented by a capital letter, and the dominant allele for white color (W) is also represented by a capital letter. Since both parents are homozygous dominant, their alleles do not carry the recessive allele for black color (r). The recessive allele for black color is represented by a lowercase letter.
When the red cow (RR) is crossed with the white cow (WW), the offspring will inherit one allele from each parent. Therefore, the possible combinations of alleles in the offspring are:
- Red cow (R) from the red parent and white cow (W) from the white parent: RW
- White cow (W) from the red parent and red cow (R) from the white parent: WR
It's important to note that this explanation assumes a simple Mendelian inheritance pattern and does not take into account other factors that could influence color inheritance in cows.
b. population
c. biome
d. organ
Answer:
The correct answer would be A) ecosystem.
Ecosystem refers to the community made up of all the living organisms (biotic component), their physical environment and all their interactions in a given space.
The biotic and abiotic components of the ecosystem are linked with the help of energy flows and nutrient cycles.
