Answer:
The dietary differences between China and the US can be explained by the cultural, social and economic background that each of these countries had.
Explanation:
The main difference in food between countries is due to the culture of each country. This culture determines which elements are apt to be consumed and which are not. An example of this is dog food in China, which is very cultural, while the US and most Western countries do not welcome dog food because of its cultural context. Another example can be seen in the feeding of guinea-pig meat in Peru, however, other Latin American countries do not appreciate this type of meat.
The economic and social history of countries can also cause dietary differences. This is because these two factors change society and promote access to more modern and archaic foods.

Which is the best definition of directional selection?
a process by which two species can no longer reproduce
a process by which one of the extreme variations of a trait is favored
a process by which individuals with either extreme of a trait are favored
a process by which average individuals in a population are favored
Answer:
B. a process by which one of the extreme variations of a trait is favored
Explanation:
The graph for this type of selection looks sort of like a camel's hump. With that being said, the phenotype of a population experiencing directional selection goes from one extreme to the other. Reference the evolution of the peppered moth during the Industrial Age as an example.
Sincerely hope this helps! God bless!A process by which one of the extreme variations of a trait is favored best describes the directional selection. Therefore, option (B) is correct.
What do you mean by directional selection?Directional selection is a negative natural selection mode in which an extreme phenotype is preferred over other phenotypes, causing the allele frequency to shift over time in that phenotype's favor.
Fossil evidence suggests that while the size of European black bears decreased during interglacial periods of the ice ages, it increased during each glacial period. This is an example of directional selection. A further illustration is the size of a population of finches' beaks.
The behavioral trait in question experiences a concentration of increasing alleles in the line selected in the upward direction and a concentration of decreasing alleles in the line selected in the downward direction.

What is a technique that aims to reduce viable spoilage microorganisms so they are unlikely to cause disease?
Answer:
Pasteurization
Explanation:
Food products such as milk, wine and beverages may be subjected or placed on a heat treatment process with the aim of reducing active microorganisms present in them. This will improve the quality of food materials and also prolong its life span. This heat treatment process help destroy pathogenic microorganisms and those which are responsible for food spoilage. Once this food spoilage microorganisms are destroyed, the good products will have enhanced or prolonged life span of the food product and also reduces their risk of causing disease.

Which of the following energy transformation occur when humans use energy from food to exercise?
Answer:
Chemical energy from food molecules (potential energy) may also be transformed to mechanical energy (kinetic energy) when the body moves. In every energy transformation, some energy is given off as heat. This is why the body warms up during different activities like exercising, lifting weights, and even digestion!

Animals in Cestoda have: Group of answer choices septa and parapodia proglottids and no digestive system a pharynx and gastrovascular cavity a water vascular system
Answer:
no digestive system
Explanation:
Animals in Cestoda have no digestive system so they takes nutrients through its cell wall. Cestodes have no digestive tract so they absorb nutrients from the host across the body wall. Most of the flatworms have conspicuous digestive systems while on the other hand, the digestive system of turbellarians consists of mouth, pharynx, and intestine so we can conclude that Cestoda have no digestive system to absorb nutrients like other organisms.

How does the experiment relate to what you've learned about submersible technology suck as submarines and ROV's?
Answer:
A submersible technology designed to operate the submarines underwater.
Explanation:
We have learned about submersible technology suck as submarines and ROV's is that pumping system is used to remove water from the submarines and ROV's in order to make it lighter. A submersible is designed to push water to the surface. When a pressure switch is turned on, the impeller started to spin drawing water into the pump. The water is then pushed through the pump and brought it to the surface. Due to removal of water, the submarines and ROV's become lighter and they will come to the surface of water.
Organisms use glucose to store and transport energy.
True
False
Answer:
Glucose and ATP are used for energy by nearly all living things. Glucose is used to store and transport energy, and ATP is used to power life processes inside cells. Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose.
Explanation:
Most organisms use glucose and ATP for energy. ATP powers cells, and glucose stores and transports energy. Photosynthesis converts sunlight into glucose for many autotrophs.
What do organisms use to store and transport energy?All living things use ATP and glucose as energy sources. Energy is stored and transported by glucose, and cellular life functions are powered by ATP. Through the process of photosynthesis, which converts solar light energy into chemical energy that is stored in glucose, many autotrophs produce food.
Glycogen is the name given to this form of glucose that is stored and is composed of several linked glucose molecules. Glycogen is broken down to release glucose into the bloodstream, which is then used as fuel for the cells, when the body needs a sudden surge of energy or when the body isn't obtaining glucose from food.

Insects: Please choose the correct answer from the following choices, and then select the submit answer button. typically have a younger flying life stage and an older aquatic life stage after metamorphosis. generally give birth to live young. typically mate and produce young during their larval stage. have a respiratory system with spiracles connecting to tracheae.
Answer:
The correct option is ( have a respiratory system with spiracles connecting to tracheae).
Explanation:
The class INSECTA are under the phylum arthropoda which is the largest phylum in the animal kingdom. The insects are mainly land animals, they are widespread and adapted to all types of environment. They are also the only invertebrates that can fly. Examples of insects include: ants, butterflies, beetles, aphids and grasshoppers.
An insect has a well-defined head, thorax and an abdomen. The head had six segments and bears a pair of jointed antennae, compound eyes, simple eyes and mouthparts. The thorax had three segments, each bearing a pair of jointed walking legs. The abdomen has eleven segments and may have sensory and reproductive structures.
An insect carries out gaseous exchange by means of a network of open air tubes or TRACHEAE inside it's body. These tubes have openings called SPIRACLES to the exterior. Therefore the insects have an respiratory system with spiracles connecting to tracheae.
