Which statement is correct concerning the chances of survival for these
species if there is a change in the environment? *
Species A
Species B
Species C
Species D
ATID
Neither species B nor species D will survive because they compete for the same
resources
Species A has the best chance of survival because it has the most genetic diversity
Species C has the best chance of survival because it has no gene mutations
None of the species will survive because bacteria reproduce asexually
Answer:
A bcoz it change the environment
Species A has the best chance of survival because it has the most genetic diversity.
What is genetic diversity?Genetic diversity is defined as the set of different inherited traits that occurs within a species. Those organisms having higher genetic diversity have more chances of survival.
So we can conclude that Species A has the best chance of survival because it has the most genetic diversity.

“How might an energy requirement affect an individual who has a cancerous tumour?”
Answer:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function. Energy is stored in the bonds of glucose (like a stretched rubber band), and when glucose is broken down, much of that energy is released. Some of it is captured in a form that can be used to do work in cells - a molecule called adenosine triphosphate or ATP. The energy that is not captured in ATP is usually given off as heat (one of the things that helps us maintain our normal body temperature).
True or false: All herbivores are autotrophs.
Answer:
false
Explanation:
Autotrophs, organisms that produce their own food, are the first trophic level. These include plants and algae. Herbivores, which eat autotrophs, are the second trophic level. Carnivores, organisms that consume animals, and omnivores, organisms that consume both plants and animals, are the third trophic level.
Which of the following is evidence of Continental Drift?
Shape of the continents
Distribution of fossils
Distribution of geological features
All of these
None of these
Answer:
All of these
Explanation:
If you put all of the continents together, they fit like a puzzle. If you look at mountains and match these when they are put together, mountains will be in similar places. The fossils found in Antarctica were fossils from warm climates. That could only be if all continents used to be one!

what is a DNA 1 paragraph pls :))))))))))
Answer:
DNA is a self replicated material that is inside almost every living animal, and human being. DNA contains genetic codes. Dna holds genes, for example those who created you, there genes are passed on to you causing it to also be in ur DNA. It contains instructions that an organism needs to live, develope and reproduce. DNA serves as the primary unit of heredity in different types of organisms. (It might not be long enough but maybe this could atleast be used as half a paragraph)
Where are chromosomes found in the human body what are chromosomes made of
Answer:
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

1. What is a stimulus?
2. Why does the body respond to stimuli?
3. What are some different types of stimuli?
4. What are sensory organs and what type of stimuli do these receptors respond to?
5. What is an explanation of how the information from stimuli is communicated to the brain?
6. What is a description of the two things that can happen when the brain processes the information from stimuli?
Hello, 3Coli Here!
Here are your answers:
1. What is a stimulus?
Stimulus is a natural body reaction caused by changes in the environment around or inside the organism. This is a response from the brain.
2. Why does the body respond to stimuli?
The body responds to stimuli, because it needs to protect itself.
3. What are some different types of stimuli?
The two main types of stimuli are external stimuli and internal stimuli. External stimuli are reactions triggered by changes that occur outside of the body, while internal stimuli are reactions triggered by changes inside of the body.
4. What are sensory organs and what type of stimuli do these receptors respond to?
The most commonly used sensory organs include Eyes, Ears, Tongue, Nose, and Skin. Eyes respond to light and motion, because they are used to see. Ears respond to sound, because they hear. The tongue is used to taste, so it senses flavors. The nose is used to smell, so it responds to scents. Finally, the skin is used to feel, so it responds to whatever it feels.
5. What is an explanation of how the information from stimuli is communicated to the brain?
Neuron receptors convert internal and external environments into electrical signals, and then is sent to the brain through nerves.
6. What is a description of the two things that can happen when the brain processes the information from stimuli?
After the brain receives the signal, it will provide a response. One type of response is that the body will physically react to the change. The second type of response is to avoid the change.

_____ is a force caused by air that slows objects down
Answer:
Drag
Explanation:
Drag is a force caused by air that slows objects down
Friction is a major force that slows the object down, air resistance is a type of frictional force.
What is air resistance?Air resistance is a kind of frictional force that slows down an object from moving in a particular direction.
During the movement an object has a particular speed for movement, speed depends on how friction works, more friction slows the speed of an object a low friction allows the object to at a particular speed.
Air is a mixture of gases and particles in the atmosphere, these particles create a force during the movement of an object in the air, and these forces decide the actual speed of object movement.
Therefore air resistance is a force that slows the object.

Which best describes the way a sound wave is sent through the radio?
sound wave → radio wave
radio wave → sound wave
radio wave → sound wave → electrical signal → sound wave
sound wave → electrical signal → radio wave → sound wave
Sound waves propagate from the sound source. The sound through radio comes through the electrical signal, radio wave, and sound wave. Thus, option D is correct.
What is a sound wave?A sound wave is an acoustic wave that travels through a medium through the disturbance of the particles in a longitudinal direction. A few examples are radio, whisper, rustling, etc.
The sound waves in radio first get converted into the electrical signal that passes through the circuit of the radio that further gets transferred as radio waves.
These radio waves are the part of the electromagnetic spectrum that travels at a little less speed than light. The radio waves again get converted into sound waves as it leaves the system and reaches the ear of the organism.
Therefore, option D. sound wave → electrical signal → radio wave → sound wave is the correct order.
