Jhich best describe the role of small intestine in digestion?
A. It temporarily stores the food
B. Secrets bile to help in digestion.
C. Helps in the absorption of nutrients from food.
D. It carries food from the mouth to the stomach.
The best option that describes the role of the small intestine in digestion is (C) it helps in the absorption of nutrients from food.
What is small intestine?The small intestine is a vital part of the digestive system, and its main role is to facilitate the absorption of nutrients from the food we eat. After food is partially digested in the stomach, it enters the small intestine, where it is broken down further by enzymes secreted by the pancreas and bile from the liver.
The walls of the small intestine are lined with small finger-like projections called villi, which greatly increase the surface area available for nutrient absorption.
As food passes through the small intestine, nutrients such as carbohydrates, proteins, and fats are absorbed through the villi and into the bloodstream, where they can be transported to the cells throughout the body to be used as energy or for other purposes.
In addition to nutrient absorption, the small intestine also plays a role in the digestion of carbohydrates and proteins, and it helps to regulate the release of digestive enzymes and hormones.
Overall, the small intestine is a crucial component of the digestive system, and its proper functioning is essential for maintaining good health and well-being.

Answer:
Explanation:
A bureaucracy has to justify itself. It always argues that acts in the best interest of those it serves. If it was me answering the question in an essay form I would choose the first choice bureaucracy as part of my topic sentence.
If you don't believe me, the income tax act in both Canada and the United States (especially in America) is one of the most complex laws ever written. So my answer for you would be Red Tape.
It's formal. It's an organization. It's not always reasonable especially if you have to deal with it. It's stable but not in a good way.

How much dna is in each nucleus of each cell
Answer: Look below =3
Explanation: That makes a total of 6 billion base pairs of DNA per cell. Because each base pair is around 0.34 nanometers long (a nanometer is one-billionth of a meter), each diploid cell therefore contains about 2 meters of DNA [(0.34 × 10-9) × (6 × 109)].
Each cell has 1 DNA. When it is mitosis, a piece of DNA breaks down into thing called chromosome.

What does this pyramid tell us about the population?
The answer is A. The population is growing.
The pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.
What is population?Population is defined as the quantity or population of people living somewhere who are a particular social, cultural, economical, ethnic, or racial category. Making decisions can be aided by knowledge of how population parameters, such as size, regional distribution, age structure, or birth and death rates, vary over time.
The pyramid is used to show the growth in population of a country or population of the city. In the pyramid the growth of population is equal in both male and female population. The pyramid shows that the population of older generation is less than the population of younger generation peoples.
Thus, the pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.

A. a phylogenetic tree. it says that i need 20 more characters to enter so this is me wasting them. but the answer is A
The given diagram basically represents a cladogram. The correct option is D.
What is cladogram?A cladogram is a type of diagram that depicts the evolutionary relationships between organisms.
It is a branching diagram in which the nodes represent the descendants' most recent common ancestor. The cladogram is based on the organisms' shared characteristics or traits.
These characteristics, which can be physical or genetic in nature, are used to classify organisms into clades.
Clades are groups of organisms that share a common ancestor, and they are represented on the cladogram as branches.
The organisms are more closely related the closer the branches are to each other. Cladograms are commonly used in biology to study organisms' evolutionary histories.
Thus, the correct option is D.

Newton's third law of motion states that whenever a first object exerts a force on a second object, the first object experiences a force equal in magnitude but opposite in direction to the force that it exerts
Question 5 options:
True
False
I need help from someone who's actually helpful and smart please
Answer:
true
Explanation:
i took the test
The statement "Newton's third law of motion states that whenever a first object exerts a force on a second object. The first object experiences a force equal in magnitude but opposite in direction to the force that it exerts" is true.
What is Newton's third law?
His third law argues that there is an equal and opposite reaction to every action (force) in nature. When object A pulls on item B, object B pulls back on object A with an equal and opposing force. In other words, interactions lead to forces.
According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.
Therefore, the statement is true.

All photosynthetic organisms have chloroplasts.
options:
1. False, only photosynthetic eukaryotes have chloroplasts
2. True
3. False, only plants have chloroplasts
All photosynthetic organisms have chloroplasts. This is definitely false because only photosynthetic eukaryotes have chloroplasts. Thus, the correct option is 1.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food with the help of carbon dioxide and water in the presence of sunlight.
Cyanobacteria are the largest and most diverse group of photosynthetic bacteria that perform photosynthesis without having the chloroplast. This type of bacterial organism is generally classified into prokaryotes.
Hence, the chloroplast is only present in the members of photosynthetic organisms that belong to the eukaryotic category.
Therefore, the statement "All photosynthetic organisms have chloroplasts" is definitely false.
