Explain how the respiratory and circulatory systems interact.
Answer:
The respiratory system interacts with the circulatory system, because the circulatory system is able to transport oxygen and carbon dioxide throughout the body from the respiratory system. Another system interaction is the sharing of the Pharnyx by the digestive and respiratory system, because it is used to swallow food and to breathe.

A.
The lizard genes spontaneously mutated to address the flooding threat.
B.
Genetic variation among lizard limbs allowed for natural selection to occur.
C.
The limbs were artificially selected because humans probably caused the flooding.
D.
The lizards with longer limbs cloned themselves, ensuring survival of the species.

HELP!!
Answer:
Explanation:
B. :) For example, camels have adapted to the scorching heat they survive in. Adaptations help a species live. :D If I helped please mark brainliest!
Adaptations affect a species by making the species more likely to survive. Thus, the correct option is B.
What is Species?Species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.
Adaptations may be defined as the process through which an organism makes itself better to be suited to the natural environment.
It increases the chances of a particular species surviving and reproducing in a natural environment.
Therefore, adaptations affect a species by making the species more likely to survive. Thus, the correct option is B.

Answer:
Decomposer
Explanation: I just did it
An organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.
What is the decomposer's importance?Decomposers are of great importance as they can maintain the ecosystem by breaking down dead organic matter and recycling nutrients back into it, later, these nutrients are passed from the environment to plants, then to animals, and then back to the environment. Decomposers include bacteria and fungi that consume dead plant and animal material, breaking down complex molecules into simpler compounds that can be used by plants to grow.
Hence, an organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.

Which causes waves in the ocean to occur?
Earth’s rotation
Earth’s gravitational pull
energy being transferred from wind
energy from the Sun heating water
Answer: Energy being transferred from wind
Explanation: I just answered this question
Waves in the ocean are occurs due to the transfer of energy from the wind. Therefore, option C is correct.
What causes waves in the ocean?Numerous events, including earthquakes, volcanic eruptions, and landslides, can result in waves, although surface waves brought on by winds are the most frequent ones (CoastalCare). A wave forms when the wind blows across the water's surface, generating friction between the air and the water.
There are numerous types of waves, including tidal waves, wind waves, ocean swells, and tsunamis. Three factors: the wind's speed, the length of time it takes to cross the ocean, and the distance it travels, all affect how large the waves become.
The most common cause of the formation of waves in the ocean is the transfer of energy from the wind. Therefore, option C is correct.

The minimum amount of muscles needed to move a joint is ______.
A. 4
B. 3
C. 2
D. 1
Answer:
C. 2 one muscle contracts while the other muscle relaxes and becomes longer
Explanation:
hope this helps :))
The minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.
What are Muscles?Muscles may be defined as the bundles of fibrous tissue in animals including humans which consist of long cells that contract when stimulated and induce movements.
Muscles play numerous roles such as maintaining the overall posture of the body, moving the skeleton, storing nutrients, providing stability, assisting respiration and digestion, etc.
A joint is migrated with the cooperation of two muscles in such a way that one provokes the contraction while the other induces relaxation at the same time. This simultaneous activity of both two muscles is responsible for the proper migration of joints.
Therefore, the minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.
