As the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.
What is Kepler's second law?Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the Sun.
This law exaplains the speed of planets around the sun, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.
From the findings, the astronomical unit of the Mercury is 0.387 and the orbital period is 0.24 year.
[tex]T \propto a^{3/2}[/tex]

If after thousands of generations, genetic mutations lead to a new separate species, we refer to this change as
O variation
Ospeciation
O adaptation
O natural selection
Answer:
speciation is the answer beacuse Genetic mutation is the basis of species diversity among beetles, or any other organism. Mutations are changes in the genetic sequence, and they are a main cause of diversity among organisms. These changes occur at many different levels, and they can have widely differing consequences.
Which of the following is a benefit of nonrenewable energy?
A.It costs less than some renewable options.
B.It uses man-made and natural resources.
C.It is unlimited or quickly replenished.
D.It is from clean energy sources.
Answer:
B. It uses man-made and natural resources.
Explanation:
Sorry if incorrect
Non-renewable energy uses man-made and natural resources. So, the correct option is B.
What are Non-renewable energy?Natural resources that cannot be easily replenished through natural means at a rate quick enough to stay current with use are considered non-renewable resources. Fossil fuels made of carbon are one instance. With the use of pressure and heat, the original biological matter transforms into a fuel like petrol or oil.
Non-renewable energy is produced using finite resources that cannot be replenished at a rate that matches the rate of use. To put things in perspective, there won't be any more non-renewable energy sources in our lives—or, more precisely, in many human lifetimes.
The majority of non-renewable sources of energy are fossil fuels, such as coal, natural gas, and petroleum and crude oil; however, nuclear fuel, which is primarily used to generate electricity, is also typically categorized as non-renewable.
Therefore, the correct option is B.

Why do you think scientists would be interested in studying cognitive behavior in animals?
Animals are used as models to learn about the human heart and lungs, and they are also utilized to learn about the human brain and nervous system. The brain, on the other hand, is far more sophisticated and nuanced than any other organ. Furthermore, animal cognition research tries to avoid issues such as which animals are smarter than others, instead concentrating on more particular concerns such as the ones listed above. Scientists frequently state that they are more interested in how well an animal has evolved to flourish in its environment than in its intelligence.

What happens if a spike protein changes shape
Answer:
When a spike protein changes its shape, it folds on itself and merges its membrane within our cell's membrane to allow itself a way in, causing an infection and the penetration of host cells.
When a spike protein changes shape, it can affect the way a virus interacts with its host cell.
What is a spike protein?The spike protein is a key component on the surface of some viruses, such as coronaviruses, and is responsible for binding to host cell receptors, allowing the virus to enter the cell and cause infection.
If the spike protein changes shape, the following can happen:
Altered binding affinity: The ability of the spike protein to bind to host cell receptors may be enhanced or diminished. This can potentially affect the transmissibility or infectiousness of the virus.
Immune system evasion: A change in the spike protein shape might make it harder for the host's immune system to recognize the virus, potentially allowing the virus to evade detection and neutralization by antibodies.
Impact on vaccines: Changes in the spike protein shape could also impact the effectiveness of vaccines designed to target the original spike protein, as the altered shape may not be recognized as effectively by the immune system.
Overall, when a spike protein changes shape, it can have various consequences for viral transmission, immune system response, and vaccine effectiveness.

a.
Bones, joints, and connective tissue
b.
Organs, muscles, and bones
c.
Bones and fascia
d.
The pulmonary and systemic circuits
Answer:
A
the answer is A!!! good luck <3
Answer:
A. Bones, joints, and connective tissue
Explanation:
The skeletal system supports and protects the body while giving it shape and form. It is composed of bone, joints, ligaments, connective tissue, and cartilage.
Organs are not included, for they are not skeletal. Fascla is a sheet of connective tissue beneath the skin that attaches to, stabilizes, encloses, and separates muscles and other internal organs. It is not part of the skeletal system.
A systemic circuit is the path of circulation between the heart and the rest of the body. It too, is not skeletal.
Hence, the answer is A.
