Which statement best describes the breakdown of food in the digestive system? Carbohydrate digestion starts in the stomach and protein digestion starts in the stomach. Carbohydrate digestion starts in the mouth and protein digestion starts in the stomach. Carbohydrate digestion starts in the esophagus and protein digestion starts in the small intestine. Carbohydrate digestion starts in the small intestine and protein digestion starts in the esophagus.
Answer:
Carbohydrate digestion starts in the mouth and protein digestion starts in the stomach.
Explanation:
Digestion of carbohydrates start at the moth with the help of salivary amylase which is an enzyme that helps breakdown the polysacharrides found in food with carbohydrates.
Protein digestion on the other hand, begins in the stomach and the duodenum. The stomach releases the enzyme called pepsin, which help breakdown the proteins, with the aid of two other enzymes, chymotrypsin and trypsin which are enzymes released by the pancreas.
Answer:
B, Carbohydrate digestion starts in the mouth and protein digestion starts in the stomach.
Explanation:
A hill is made of rock particles of different sizes. Which of these agents of
erosion probably caused the hill to form?
A. Glacialice
B. Waves
C. Wind
D. Flowing water
Answer: The answer is A. Glacial Ice
Explanation:
Final answer:
Flowing water is the most probable agent of erosion responsible for the formation of a hill made of rock particles of different sizes, due to its capacity for erosion and deposition based on particle size and gravity's role in pulling it downhill.
Explanation:
A hill made of rock particles of different sizes is likely influenced by several agents of erosion. Among the listed options, flowing water is the most probable cause for the formation of such a hill. Flowing water can transport rock particles of various sizes through erosion and deposition processes. As water moves over land, it picks up smaller particles first, leaving behind larger particles which can accumulate to form a hill. Besides, water moving over steeper slopes increases erosion potential, contributing to the shaping of the landscape.
Although other agents like glacial ice, wind, and waves can also cause erosion, they are less likely to be responsible for the formation of a hill comprised of rock particles of mixed sizes. Glacial ice, for instance, typically forms more uniform deposits and has a distinct erosion pattern, including features like U-shaped valleys rather than hills mixed with varying particle sizes.
It is important to note that gravity also plays a role in the process of erosion by pulling water and ice downhill, which in turn shapes the earth's surface. Flowing water also contributes to the formation of distinctive geological features through the differential erosion of rocks with varying levels of erosion resistance.

6. Which statement about seagulls and sea stars is true?
A Seagulls are the prey of sea stars.
B Sea stars are the prey of seagulls.
O
C
Sea stars are the predators of seagulls.
D Sea stars are the hosts of seagulls.
Answer:
B. Sea stars are the prey of seagulls
Explanation:
Seagulls eat sea stars, meaning that sea stars are their prey (the organism that is eaten).
Predator: an organism that eats (preys on) another organism
Prey: an organism that is eaten by another organism (creatures can be both predator and prey. For example, a rabbit is a predator to grass, while they are prey to foxes)
Host: An organism that is fed on by a parasite. Think of a dog with a tick. The dog is the host, the tick is the parasite.
Incorrect answers (and why):
A. Sea stars do not eat seagulls
C. If a sea star was a predator to a seagull, that would mean that they eat seagulls. They do not.
D. A host is an organism that a parasite preys on. Not only are sea stars not parasites, but they definitely do not prey on seagulls.

Refer to the family pedigree shown here. In generation I, one parent is affected by the gene mutation and one parent isn't. In generation II, all three children are affected by the gene mutation. What can you conclude about this gene mutation?
A. All children born in future generations will be affected by this disorder.
B. This gene mutation is a dominant disorder.
C. This gene mutation is a recessive disorder.
D. The generation I mother is a carrier of this gene mutation.
Answer:
B. This gene mutation is a dominant disorder.
Explanation:
Since all the children in generation III do not have the disorder, there is no indication that all the children born in the future generations will be affected by this disorder.
The gene mutation appear dominant from the pattern of inheritance. The children in generation II are all affected because there are two dominant alleles for the disorder in the father. Some of the children in generation III do not have the disorder because only one allele is dominant in the mother, hence, the unaffected children inherited the non-dominant allele from the mother.
The gene mutation is not recessive, otherwise, not all the offspring in generation II are supposed to be affected for the disorder.
The mother in generation I cannot be a carrier because the disorder is a dominant one. There can only be heterozygous for a dominant disorder but they are usually phenotypically affected for the disorder.
The correct option is B.
Answer:
B. This gene mutation is a dominant disorder.

What are the functions of Uterus?The uterus is an organ of the female reproductive system. It’s shaped like an upside-down pear and has thick walls. The main function of the uterus is to house and nourish a fetus until it’s ready for birth.If conception occurs, the fertilized egg (the embryo) burrows into the endometrium from which the maternal portion of the placenta, the decidua basalis, will develop.As pregnancy progresses, the uterus grows and the muscular walls become thinner, like a balloon being blown up, to accommodate the developing fetus and the protective amniotic fluid produced first by the mother and by the urine and lung secretions of the baby.During pregnancy, the muscular layer of the uterus begins contracting on and off in preparation for childbirth.Hence, option A is the answer.

How does competition increase stability in an ecosystem?
A a decreases biodiversity
B it keeps population balanced
C it causes cyclical disturbances
D it removes keystone species
Answer:
b
Explanation:
so that the habitat doesnt get overcrowded
The competition increase stability in an ecosystem by keeping population Balanced.
Explanation:
There is increase in competition this will in turn deals with stability in ecosystem. Because this creates continuous food chain where a larger animal will eat the smaller one and this cyclical chain keeps in check. The food chains creates complexities in the biodiversity this again is compensated with increase in population. With a lot more increase in species again the food chain demands the cyclical procedure. This is how in our biodiversity the stability in the organism is maintained.

Can nonrenewable resources be used sustainably?
A. Yes, nonrenewable resources are always beneficial for the environment
B. No, there are only negative effects of using nonrenewable resources
C. No, there's a finite amount of nonrenewable resources
D. Yes, as long as use doesn't exceed availability
is the correct answer
D. Yes, as long as use doesn't exceed availability
Answer:
C
Explanation:
we know non renewable resources once used up can't be replenished, the question of can it be used sustainably certainly does not present a good picture of its use. It is certainly more difficult to replace such resources.
D. Yes, as long as use doesn't exceed availability.
Nonrenewable resources, such as fossil fuels (coal, oil, natural gas) and minerals (like metals), are finite in nature and cannot be replenished over short timescales. However, they can be used sustainably if their extraction and consumption rate do not exceed their natural rate of formation or replenishment over geological timeframes.
Option D is the correct statement because it highlights the possibility of using nonrenewable resources sustainably by ensuring that their usage does not deplete them faster than they can naturally be replaced. Sustainable use involves managing the extraction and consumption of nonrenewable resources in a way that considers their finite nature, seeks efficiency in utilization, and promotes the development and adoption of alternative, renewable, or more sustainable energy and material sources.
On the other hand, options A and B are incorrect. Nonrenewable resources can have both positive and negative effects depending on their usage and management. While they have been essential in driving modern industrial development and economic growth, their use is associated with environmental impacts like greenhouse gas emissions, air and water pollution, habitat destruction, and climate change.
Option C is partly true as nonrenewable resources are indeed finite, and their quantities are limited. However, just because they are finite doesn't mean they cannot be used sustainably. Sustainable use involves making informed decisions about their utilization, maximizing efficiency, and exploring alternatives to ensure a balance between meeting current needs and conserving resources for future generations.

What is a difference between systemic and pulmonary circulation? A. Systemic circulation carries oxygenated blood to the lungs and pulmonary circulation carries deoxygenated blood to the body. B. Systemic circulation carries deoxygenated blood to the lungs and pulmonary circulation carries oxygenated blood to the body. C. Systemic circulation carries deoxygenated blood to the body and pulmonary circulation carries oxygenated blood to the lungs. D. Systemic circulation carries oxygenated blood to the body and pulmonary circulation carries deoxygenated blood to the lungs.
Your answer would be D, Systemic circulation carries oxygenated blood to the body and pulmonary circulation carries deoxygenated blood to the lungs.
These two circulations are part of the circulatory system, with the pulmonary circulation taking deoxygenated blood to the lungs and returning it oxygenated with the oxygen we breathe in, then that oxygenated blood going around the body delivering that oxygen and coming back deoxygenated.
Hope this helped!
In pulmonary circulation, deoxygenated blood is pumped from the heart's right ventricle, while in systemic circulation, oxygenated blood is pumped from the heart's left ventricle. thus option D is correct.
What are pulmonary and systematic circulation?Pulmonary circulation begins with the right ventricle sending deoxygenated blood to the lungs, where it is oxygenated before returning to the heart in the left atrium. while in the systemic circulation, oxygenated blood is pumped from the heart's left ventricle.
The pulmonary circulation's major purpose is to exchange gases (CO2 and O2) between the blood and the air.
The vascular system that distributes blood from the left ventricle to all of the body's tissues is known as systemic circulation.
The systemic circulation is in charge of maintaining a consistent blood flow via the capillaries in order to facilitate nutrient diffusion.
Finally, deoxygenated blood is pumped from the right ventricle of the heart in pulmonary circulation, whereas oxygenated blood is pushed from the left ventricle in the systemic circulation.

2.) Would a plant grow better in a room painted blue or in a room painted green? Explain your answer.
Answer:
A blue room
Explanation:
Green light is the least effective for plants because they are themselves green due to the pigment Chlorophyll.. Blue light helps encourage vegetative leaf growth, and red light encourages flowers. this happens because the amount of blue, red and far red spectrum of light that reaches the planet changes with the seasons. As days start to get longer, more blue spectrum light reaches the surface of the earth. This initiates a vegetative growing stage for most plants leading into the spring and early summer. As the days start to grow shorter, and more of the red and far red spectrum reaches the surface, it leads into the late summer and fall reproductive season.
give an example in which the electrical energy changes to sound energy
Answer:
Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal.
Explanation:
Please mark brainliest and have a great day!
Vibrations.
➤ Reason[[Im mainly going of the knowledge I already know, I don't know if I'll be wrong about any of this.]]
Electric energy is energy in general, which can totally cause somewhat disturbing vibrations to the surrounding area. Examples of this are thunder, but, the reason this doesn't count as it is actually converting electric energy, into heat energy, into sound energy. The heat warms up the air so fast it creates a wave of pressure, a shock wave, which is powerful enough to rumble into the distance for miles. What would count is electrical energy by itself. Everyone has heard the sound electricity makes when it zaps and buzzes. It can be rather loud to. This is the energy from the electricity causes vibrations, which is sound energy that can be heard by our ears. Electricity can also power things such as speakers which turn electrical pulses into sound that we can hear with our ears, which is kinda amazing. Science is epik.

Hope this helps!
The energy stored in the sucrose molecule is stored in the bonds between the atoms.
Option C
Explanation:
During photosynthesis the sugar molecules are synthesized with help of captured light energy. The bonds between the carbon atoms of sucrose molecule are the covalent bonds and during their breakdown they produces reduced co-factors like NAD and FAD into NADH and FADH2. These reduced cofactors transfer their electrons into electron transport chain which later help ATP synthase to catalyse the production of ATP. Hence the bonds which were made by utilising the photon energy of sun are responsible for the production of energy molecule ATP so the energy is stored in the the bonds between the atoms of sucrose molecule.
