Rosa drew a flow chart of the carbon cycle. Flow chart of the carbon cycle with 4 boxes connected by arrows. Box 1: carbon dioxide in the atmosphere. Box 2: X. Box 3: consumers eat producers. Box 4: Y. The arrow that follows box 4 connects to box 1. Which labels best complete the flow chart?
Answer:
(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.
Explanation:
(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.
(b) X: Decomposers return carbon to the soil and release waste. Y: Producers undergo photosynthesis.
(c) X: Decomposers take in carbon dioxide. Y: Producers absorb carbon through their roots.
(d)X: Producers absorb carbon through their roots. Y: Decomposers take in carbon dioxide.
Box 2 (X) would be the process through which producers fix carbon dioxide to produce their own food, the carbohydrate. The process is otherwise known as photosynthesis and can be represented by the following equation:
[tex]6CO_2 + 6H_20 --> C_6H_1_2O_6 + 6O_2[/tex]
Box 4 (Y) would be the process of decomposition. Both producers and consumers eventually die and decompose in the soil. During this process, some of the carbon returns to the soil as organic matters while the process of microbial decomposition releases carbon dioxide into the atmosphere.
The correct option would be (a).

A school bus transporting students to school is an example of
a
potential energy because it has the ability to take the students to school
Ob
kinetic energy because it has the ability to take the students to school
Ос
potential energy because it is taking the students to school
O d
kinetic energy because it is taking the students to school
Answer:
2.kinetic energy because it has the ability to take the students to school.
Explanation:
Energy of a given system due to the virtue of the motion of the given system is known as kinetic energy of the system
now we know that
so kinetic energy depends upon mass of the system and the velocity of the system.
So here since bus is in motion and moving towards the school so the bus along with all the children must have kinetic energy in it
So here correct answer would be
2.kinetic energy because it has the ability to take the students to school.

The distinct characteristics of different cell types in a multicellular organism are produced mainly by the differential regulation of the genes.
What is gene regulation?Genes are responsible for the synthesis of protein molecules in the cell.
All the cells of a living organisms contain the same sequence of genes, however, they differ in the way they are expressed.
This makes cells exhibit different characteristics in the same living organism.
Therefore, the distinct characteristics of different cell types in a multicellular organism are produced mainly by the differential regulation of the genes.

why you SHOULD NOT drink salt water if stranded at sea.
Answer:
Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body normally gets rid of excess salt by having the kidneys produce urine, but it needs freshwater to dilute the salt in your body for the kidneys to work properly.

Fernando is an engineer at an amusement park who is experimenting with changes to the setup for a magnetic roller coaster ride. In one ride, there are two identical roller coaster cars (red and yellow) that start on opposite sides of a large magnet located in the center of a station. He moves both cars, so each car ends up one space farther away from the large magnet.
How did the potential energy of the two cars change? Did the potential energy of one car change more than the other? Why do you think
I think that the potential energy of the cars will go down because the cars are moving farther away from the big magnet. Since the pols of the cars and big magnet are opposite and not the same they would want to attract if they got close to the big magnet, but since Fernando is pulling the carts away they loose that potential energy. I also think that the red cart changed more than the yellow cart because it is closer to the magnet which can have a lot of potential energy and he is now bringing the cart away from it. In conclusion, I think the red cart had a greater change in potential energy and the two cars changed in potential energy too.

d- ant, grass, snail
Answer:
option : d
Explanation:
A biotic factor is a living organism
A biotic factor (also called a biotic component) is a living thing that affects other things ant, grass and snail.
What are producers?Producers are any kind of green plant. It makes it food by taking sunlight and using the energy to make sugar.
The plant uses this sugar, also called glucose to make many things, such as wood, leaves, roots, and bark.

Student Cell Organization Nucleus Present
Glenda single-celled
Sam single-celled
yes
Tremica multicellular
no
Thurman multicellular
yes
no
Answer:
The student who correctly identified the two characteristics of Eubacteria was Glenda (option A).
Explanation:
Eubacteria are unicellular prokaryotic microorganisms, provided with membrane and cell wall.
One of the distinctive characteristics of Eubacteria is their inability to associate and form tissues, as eukaryotic bacteria do, so they are unicellular organisms. In addition, they lack a nucleus, their genetic information is dispersed in the cytosol and they do not possess most of the organelles.
Eubacteria can be found on any surface and some of them can be considered harmful to living beings.
