B. to secrete waste products that are harmful to the human body.
C. to produce sex cells that join to form a developing baby.
D. to store iron that will be used to make red blood cells.
Answer:
to pump blood through the veins and arteries of the human body
Testes in man and ovary in female is a part of the reproductive organ which produce gametes, after fertilization to develop a baby, hence c is the correct option.
What are reproductive organs?
Female reproductive organs consist of the ovary which generates the ovum a female gamete that is responsible for fertilization.
Males consist of consisting of tests that generate the sperm male gamete which is responsible for fertilization.
Both organs are necessary to produce a gamete for fertilization which develops a zygote and makes the baby is developing of the cells.
Therefore, for producing sex cells ovaries and testes are important organs, hence option c is correct.

Answer:
R=55ohms I=2amps
Explanation:
To find total resistance add up all the resistances and then to find amperage divide the voltage by the total resistance.
I'm not sure if it says 110 or 118 volts so divide whichever it is by 55 to get the correct answer for current.
R=10+15+30
55 is the answer to the question
3. Which type of fossilization occurs when a sticky substance from plants captures and preserves an organism?
Permineralization
Mold
Fossil Resin
Tar
Answer:
Fossil Resin
Explanation:
The type of fossilization that occurs when a sticky substance from plants captures and preserves an organism is Fossil Resin.
Fossil resins are usually trapped in the resin that some trees and plants including amber, copal, and retinite exude.
Amber is also a fossil resin. Under the right conditions, resins polymerize and turn into copal. Copal matures into amber after several million years.

Answer:
enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily. reaction coordinate diagram showing the course of a reaction with and without a catalyst. with the catalyst, the activation energy is lower than without. and enzymes work on laundry stains because stains are made of different types of molecules, a range of enzymes are needed to break them down. proteases break down proteins, so are good for blood, egg, gravy, and other protein stains. amylases break down starches, and lipases break down fats and grease.

Explanation:
There are three R's of solid waste management: Reduce, Reuse, and Recycle.
Reduce allows the reduction of waste; Reuse allows the using the old or wastes again; and recycle allows the transformation of waste material into the new product rather than throwing it.
In the given example, Carol creates compost from the garden waste in her house so she is following "Recycle" management and turning garden waste into a new useful product that is compost.

A ride at an amusement park moves the riders in a circle at a rate of 6.0 m/s. If the radius of the ride is 9.0 meters, what is the acceleration of the ride?
Answer:
Acceleration of the ride = 4 m/s²
Explanation:
Given:
Velocity = 6 m/s
Radius = 9 m
Find:
Acceleration of the ride
Computation:
Centripetal acceleration = v²/r
Acceleration of the ride = 6² / 9
Acceleration of the ride = 4 m/s²
Answer: The acceleration of the ride is 4.0 meters
