what human activities can redistribute carbon loads in the cycle so that global warming might slow down or decrease choose two different real world examples and explain the flux in carbon loads that would result from an increase in that human activity. make sure to explain what biological physical or geological process would shift the carbon load from one point in the cycle to another.
Answer:
Reducing the use of fossil fuels in vehicles.
Explanation:
Reducing the use of fossil fuels in vehicles and use of electric vehicles which reduces air pollution as a result decrease or slow down of global warming occur. Use of fossil fuels is the main reason for increasing carbon concentration in the environment. If more plants were planted around the world the high concentration of carbon decreases in the environment due t photosynthesis of plants. Avoid use of activities that increases the carbon concentration in the environment.

What are the 2 main components of the Central Nervous System?
Answer || The central nervous system and the peripheral nervous system.
The nervous system is a complex system that is made up of nerves and nerve centers in different organisms that carries messages to and from the brain and the spinal cord to send them into various parts of the body.
It is primarily divided into :
1 ) CNS that is central nervous system ( made up of brain and spinal cord). The CNS is responsible for the voluntary functions of the body.
2 ) PNS that is peripheral nervous system ( possess cranial and spinal nerves arising from brain and spinal cord respectively). It controls the involuntary functions of the body.

Trisha measured the
volume of a cube using a
ruler. The length, width and
height all measured 8 cm.
The mass of the cube was
128 9. what is the density of
the cube? help
Answer:
0.25
Explanation:
density = mass / volume
data given :
mass=128 g
volume of a cube = L *L *L (L is length)
=8*8*8
=512 cm³
density = 128/512
=0.25 g/cm³
Trisha measured the volume of a cube using a ruler. The density of the cube is 0.25 g/cm³.
What is density?
The mass per unit volume is known as density. A scalar quantity, density. It is represented by the letter D, and the Greek letter rho is used as the sign for density. Mass divided by volume is how density is computed.
Mass is a physical body's total amount of matter. Mass is defined as the sum of the moles of the material and the compound's molar mass. Volume is the space taken by an object
Given the mass = 128 g
The volume of a cube = L x L x L (L is length)
Putting the value in the formula
8 x 8 x 8 =512 cm³
Density is mass/volume
Putting the value in the formula
density = 128 / 512 = 0.25 g/cm³
Thus, the density of the cube is 0.25 g/cm³.

What ratio of guinea pigs in the offspring would you predict from a Ss x ss cross?
Answer:
75:25
75% S
25% s
Explanation:
The ratio of guinea pigs in the offspring that we would predict from a Ss x ss cross is 1:1.
What is a genetic cross?
The deliberate breeding of two different individuals that results in offspring that carry part of the genetic material of each parent.
In a cross between a heterozygous dominant (Ss) guinea pig and a homozygous recessive (ss) guinea pig, the expected genotypes would be :
Ss (heterozygous dominant) :1ss (homozygous recessive) : 1S, for every guinea pig that is homozygous dominant (Ss) there will be 2 guinea pigs that are homozygous recessive (ss), resulting in the ratio of 1:1. Therefore, both the ratios will be equal. Therefore, the resulting progeny will have both the genotypic and the phenotypic ratios sames.

Answer:
Explanation:
Punnet square is a square diagram used to predict the genotypes of the offspring of a particular cross or breeding experiment.
It represent 4 offsprings of the cross between two parents. Each punnet contain the alleles in the right combination and proportion.
Punnet square is use to determine the percentages of different genotypes present in the offspring of two parents and to determine missing alleles in a cross.
it can also be used to predict the percentages of phenotypes in the offspring usually from a parents with known genotypes.

A. The mass of the egg white increases as the volume of the enzyme increases
B.The egg white is unaffected by the differing amounts of enzyme
C. Digestion decreases in each stomach as more of the egg whites surface area becomes exposed
D. Digestion increases as the volume of the enzyme increases
Answer:
D
Explanation:
The correct answer would be that digestion increases as the volume of the enzyme increases.
Protein digestion is catalyzed by the pepsin enzyme and aided by HCl. The combined actions of both substances form the basis for the digestion of protein in the stomach. Hence, one would expect the digestion of the boiled egg white to increase with the increase in the volume of the enzyme - all other factors remaining constant.
The correct option is, therefore, D.

B. They release acids that help break down the rock to form soil.
C. They replace smaller trees and shrubs that can't get enough sunlight.
D. They add nutrients to the rock and have roots that hold the rock together.
Answer:
B
Explanation:
Did it on AP5X
Lichens prepare bare rock to support the growth of plants by releasing acids that help break down the rock to form soil. Thus, the correct option for this question is B.
What are Lichens?Lichens may be defined as a complex life form that is a symbiotic partnership of two separate organisms, a fungus, and an alga. In this symbiosis relationship between two organisms, the dominant partner is the fungus, which gives the lichen the majority of its characteristics, from its thallus shape to its fruiting bodies.
Lichens are important as early-stage primary succession organisms. They are keystone species in many ecosystems. They serve as a food source and habitat for many animals such as deer, birds, and rodents. They provide nesting materials for birds. They protect trees and rocks from extreme elements such as rain, wind, and snow.
Lichens contribute to soil formation by decomposition as well. There are two primary types of decomposition that contribute to the formation of soil: in-situ decomposition and litterfall.
Therefore, the correct option for this question is B.

More than one statement might match a diagram, and some diagrams may not match any statement.According to model 1, do helper T-cell interact with a free pathogen in the blood?Answer
The pathogen in the model is represented with a star.The first diagram in the model represents the phagocytosis process. And the phagocyte cell is represented by the bigger irregular cell. In model 1, T cells are the perfectly circular-shaped cells with the Th inside. And the surface proteins in the T-cell are those sticks attached to their membranes. If you look at the model carefully, you will see that these proteins are different in each T-cell. The union site with the antigen changes from cell to cell, making each T-cell specific. One cell has squared binding sites, the other one has semicircular binding sites, while the last one has triangular binding sites. Order of statements: Pathogen is broken appart by chemicals in the phagocyte (Diagram 1 - 3th cell) A piece of pahtogen is presented on the surface of the phagocyte (Diagram 1 - 4th cell) The helper T-cell binds to the piece of pathogen presented on the phagocyte (Diagram 3)The helper T-cell disperses a chemical signal to activate other immune response systems (Diagram 4)T-Cells do NOT interact with free pathogens.
