Evolution :).
Descent with modification helps to explain anatomical similarities among certain species. The bones of the forelimbs of humans, cats, and bats (you can add in penguins, alligators, and more) are used in different ways but have similar structures.
The best explanation is that these animals have a common ancestor. With new generations, new species emerged by natural selection from different populations, and with this, the bones become better for different tasks.
The forelimbs and other such structures with anatomical similarities due to a common ancestor are called homologous structures.
Answer:
primary, secondary
Explanation:
primary immunodeficiency diseases are present at birth and usually stem from genetic errors, whereas secondary immunodeficiency diseases are acquired after birth and are due to agents such as infections, irradiation, or steroids

True
Explanation:
If the net force on an object at rest is zero, the object will remain at rest. This is one of the postulates of newton's law of motion.
Newton's first law of motion states that "an object will continue in its state of rest or uniform motion unless if it is acted upon by an external force. "
- If no net force acts on a body, it will forever remain at rest.
- The force on a body causes its motion and acceleration.
- A body will continue in uniform motion if no external force acts on it.
