Glucagon and insulin have antagonistic effects, with glucagon promoting glucose production and release into the bloodstream, and insulin promoting the transport of glucose into cells from the bloodstream and inhibiting glucose production. In which way this two component work together to make sure your still at homeostasis.
Answer : (1) The correct option is, (A) increases
(2) The correct option is, (C) Decreases
Explanation :
Gravitational force : It is defined as the gravitational force is directly proportional to the product of the masses of the two object and an inversely proportional to the square of the distance between the two object.

where,
F = gravitational force or gravity
M and m = mass of two object
r = distance between the two object
G = gravitational constant
When the mass of an object increases then the gravitational force or gravity is increases because gravitational force is directly proportional to the mass of an object.
When the distance between the two object increases then the gravitational force or gravity is decreases because gravitational force is inversely proportional to the distance between the two object.
Hence, (1) As mass increases, gravity increases. (2) As distance increases, gravity decreases.
I'm sorry but I need a little bit more context
It’s either A or D, in my opinion I would go for D. Plants were needed to produce carbon dioxide.
EXPLANATION : Plants are really important for the planet and for all living things. Plants absorb carbon dioxide and release oxygen from their leaves, which humans and other animals need to breathe. Living things need plants to live
Answer: alleles
explaintion: The majority of human genes are thought to have more than two alleles. Traits controlled by a single gene with more than two alleles are called multiple allele traits
