Answer:
Almost all of the cells in your body share the same DNA so false deku here! :3
Explanation:
Answer:
False.

All cells do NOT have the same genes due to genetic variation. The reason we have different genes for different cells is to allow the cells to do different things, otherwise all cells would perform the same function.
Which three organs are part of the digestive tract?
A) salivary glands, gall bladder, appendix
B)teeth, tongue, mouth
C)esophagus, stomach, small intestine
D)esophagus, liver, pancreas
Answer:
C
Explanation:
Due to the stomach and small intestine being part of the digestive tract and the esophagus allowing food, liquids and air to enter the torso
Esophagus, stomach, small intestine are part of the digestive tract. Therefore option C is correct.
The digestive tract, also known as the gastrointestinal tract, is responsible for the process of digestion in the human body. It consists of a series of organs that work together to break down food and absorb nutrients.
The three organs that are part of the digestive tract are the esophagus, stomach, and small intestine.
The esophagus is a muscular tube that connects the mouth to the stomach and helps in the transportation of food. The stomach is a sac-like organ that mixes and churns food with digestive enzymes and acids.
The small intestine is a long tube where the majority of digestion and absorption of nutrients occurs.
Therefore option C esophagus, stomach, small intestine is correct.

Explain how the lungs are adapted for diffusion of gases
Answer:
well u know how we breath air in its the same as gas so your lungs are used to narcotics like smoking and vaping and stuff
Explanation:
Answer: Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
Explanation: The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.

Answer:
1/4 will have ss trait
Explanation:
other 2/4 will be carrier(Ss) and other 1/4 will have both dominant trait (SS)
Answer:
B. 1/2
Explanation:
The genotypes of the parents are Ss and Ss. We know this because Heterozygous basically means different alleles. The punnet square of this problem will show that the possible genes given to the offspring are SS (capital letters mean dominant. keep in mind that sickle-cell anemia is a recessive trait, meaning it is written in lowercase), Ss, Ss, or ss. So this means the offspring will have a 1/2 chance of becoming heterozygous (Ss).
What best explains why there's fewer secondary consumers than producers?
Answer:
because of inefficiency
Explanation:
The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. ... Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.

This external structure is often a feature of bacterial pathogens; it aids in allowing the bacterium to counteract the body's immune system cells, such as avoiding phagocytosis.
Answer:
Bacteria capsule.
Explanation:
The bacteria capsule is a layer of polysaccharides that is around the bacteria membrane. Its principal function is to protect the bacteria from dehydration, destructive toxins, and cells that can destruct the bacteria, such as phagosomes. As a result, the bacteria have a higher probability of surviving and colonizing.

compare and contrast the rock cycle and the carbon cycle
Answer:
The rock cycle and water cycle overlap with erosion, transporting, and deposition.carbon atoms are used repeatedly on Earth and cycled between the atmosphere, hydrosphere, biosphere, and lithosphere through processes
Explanation:
The rock cycle and the carbon cycle are two different types of natural cycles that occur on earth. The difference include components, processes, time scale, human impact, and environmental implications.
What is the difference between rock cycle and carbon cycle?The rock cycle is a continuous process that occurs over millions of years, during which rocks are transformed from one type to another. There are three major types of rocks: igneous, sedimentary, and metamorphic. Each type of rock is formed through a different process.
The carbon cycle is the process by which carbon is cycled between the atmosphere, oceans, and living organisms. Carbon is essential for life, and is found in all living organisms. The carbon cycle is driven by photosynthesis, respiration, and decomposition.
During photosynthesis, plants absorb carbon dioxide from the atmosphere and use it to build organic molecules. These organic molecules are then consumed by other organisms, and carbon is transferred up the food chain.
When organisms die, their bodies are decomposed by bacteria and fungi, which release carbon dioxide back into the atmosphere.
In addition, carbon is stored in fossil fuels such as coal, oil, and natural gas, which are formed from the remains of ancient plants and animals. When these fuels are burned, carbon is released into the atmosphere, contributing to global warming.

1. At the freezing point, the particles in an object have no kinetic
energy.
2. On the Celsius temperature scale, there are no negative
numbers.
3. The more particles an object has at a given temperature, the
more thermal energy it has.
4. Object A is much larger than Object B, but both are made of
the same material. If both objects are at the same temperature, the thermal energy
of Object A is the same as the thermal energy of Object B.
5. When heat is absorbed by an object, the speed of the particles
in the object is unchanged.
Answer:
true
Explanation:
False. At the freezing point, the particles in an object have some kinetic energy.
False. On the Celsius temperature scale, there are negative numbers.
True. The more particles an object has at a given temperature, the more thermal energy it has.
False. Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
False. When heat is absorbed by an object, the speed of the particles in the object is changed.
Explanation:
The temperature is defined as the measure of hotness and coldness.It is measured in terms of degrees Celsius, Kelvins, degrees Fahrenheit.There are negative numbers on the Celsius temperature scale and Fahrenheits temperature scale but not on the Kelvin temperature scale.It is a measure of the average kinetic energy of the particles of the object.The hotter the object, the higher will be the kinetic energy of the particles of the object, higher will be the value of temperature. The colder the object, the lower will be the kinetic energy of the particles of the object, lower will be the value of temperature.The object with more mass will have more particles and more will be the kinetic energy associated with the particles.When heat is added to an object to raise its temperature the kinetic energy of the particles increases. As kinetic energy is directly linked with speed or velocity.So from this, we can conclude that :
At the freezing point, the particles in an object have some kinetic energy.
On the Celsius temperature scale, there are negative numbers.
The more particles an object has at a given temperature, the more thermal energy it has.
Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
When heat is absorbed by an object, the speed of the particles in the object is changed.

a sailboat moves faster as the wind blows on its sail. this is an example of acceleration, force, speed, velocity
Answer:
force
Explanation:
Gravity and buoyancy are the two key forces that operate on a stationary sailboat. The power of the wind pulls on the sail in order for the boat to move which allows the boat to move. The powers are now unbalanced, which is apparent from the acceleration of the ships.
The boat accelerates until the forward portion of the force from the sails is matched by the drag from the water.
