growth hormone and insulin are protein hormones that regulate carbohydrate metabolism by hepatocytes through the activation of intracellular signaling pathways. researchers investigative whether the two hormones trigger the same or different intracellular signaling pathways in hepatocytes. the researchers added either growth hormone or insulin to parallel cultures of hepatocytes. at several times points after the hormone addition they purified total intracellular protein from the cells and quantified the level of the phosphorylated forms of two proteins involved in two different signaling pathways (figure 1, A and b) .identify a dependent variable in the experimental design identify negative control for the effects of hormone addition identify a likely reason why the researchers continue their experiments for 240 minutes
What factors contribute to Earth's tides? Choose more than one answer.
A.Change of seasons
B.The gravitational pull of the Moon
C.Radiation from the Sun
D.Earth’s rotation
E.Moon’s orbit around Earth
F.Earth’s orbit around the Sun
Answer:
B, E, F, D
Explanation:
The tide is largely controlled by the moon's gravitational pull.
The sun and moon both effect the tide.
Although the Earth's rotation has a smaller role, I included it as well.
The factors that contributes to Earth's tides are gravitational pull of the Moon, Earth’s rotation, Moon’s orbit around Earth, and Earth’s orbit around the Sun. The correct options are B, D, E, and F.
What are tides?Tides are the rise and fall of sea levels caused by the combined effects of the Moon's gravitational forces, as well as the Earth and Moon orbiting each other.
Tide tables can be used to predict tide times and amplitudes for any given location.
High as well as low tides are resulted by the moon's gravitational pull on the Earth and the Earth's rotational force.
The side of the Earth closest to the Moon experiences the strongest Moon's pull, causing the seas to rise and creating high tides.
One major force that causes tides is gravity. Ocean tides are caused by the sun's and moon's gravitational attraction to the earth's oceans.
Thus, B, D, E, and F are correct options.

how does the law of conservation of energy apple to virbatioin
Answer:
As objects move around over time, the energy associated with them—e.g., kinetic, gravitational potential, heat—might change forms, but if energy is conserved, then the total will remain the same. Conservation of energy applies only to isolated systems.

How does convection work and how does it move tectonic plates? *
Answer:
Convection is the process of warm fluids rising and cooler fluids sinking. Inside the Earth, convection is powered by heat mostly from the core. The slow circulation of rock in the mantle moves the tectonic plates at the surface.

What do you call the overall force acting on a object
Answer:
It's called a resultant force.
Explanation:
You see, there may be more than one direction of a force acting on an object so if both forces are of equal strength, the object doesn't move, but if one force is stronger than the other, the resultant force would tilt towards that force and the object would move that direction. It is the resultant force that decides where the object would go based on the forces acting on it.

What is the correct type of circulatory system for members of class Reptilia?
Open - Oxygen is delivered to organs by blood washing over organs in the body cavity.
Closed - Oxygen is delivered to organs by blood traveling through arteries and veins.
O Closed - Oxygen is delivered to organs by blood washing over organs in the body cavity.
O Reptiles don't have a circulatory system.
Answer:
Closed the first one
Explanation:
In amphibians, reptiles, birds, and mammals, blood flow is directed in two circuits: one through the lungs and back to the heart, which is called pulmonary circulation, and the other throughout the rest of the body and its organs including the brain (systemic circulation).
most mammals, have closed cardiovascular systems. The two main circulation pathways in invertebrates are the single and double circulation pathways.

A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.
What is nucleotide?It is the sub units and buIlding blocks of DNA. It is made up of a five-sided sugar, phosphate group and then a nitrogen base.
These groups make the backbone of the DNA helix. If you look at a DNA helix, they make the side of the ladder or the side portion. They connect to a nitrogen base which make the steps of the ladder. The type of sugar that is used in a DNA helix is called deoxyribose.
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine. Purines on the other hand make 5-sided and 6-sided rings.
Therefore, A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.

Why are plants, but not animals, thought to be an important factor in classifying a land biome?
Answer:
becuase plants make up surrounding areas, if you see no plants and soil with no fertilization from plants it is most likely a desert, and a place with tall and thick plants is most likely a forest
Answer:
Explanation: Because the biome must support the plant since the grow a plant you must have good temperature the constant rainfall and the soil, that is why plants are the most important factor since its chooses what plant can survive in that biome.

Explanation:
The device used to determine the probable outcome of genetic crosses, is called a punnet square.
We know that genes are units of inheritance located in the chromosomes and control different traits in living things. Genes mostly occur in pairs. The pairs of genes are called alleles. The observed traits of an organism is called its phenotype and it depends on the combination of genes.
A punnet square as shown is used to determine the most probable outcome of the crossing of genes in individual organisms.

chemical reactions that absorbs more energy than they release are considered to be
Chemical reactions that absorbs more energy than they release are considered to be endothermic.
What is endothermic reactions?Endothermic reactions involve the absorption of heat from the surroundings, resulting in a decrease in temperature of the surroundings. In these reactions, the reactants have lower energy than the products, and the difference in energy is absorbed as heat from the surroundings. Examples of endothermic reactions include the melting of ice, the evaporation of water, and the reaction of baking soda and vinegar.
In contrast, exothermic reactions release more energy than they absorb, resulting in an increase in temperature of the surroundings. Examples of exothermic reactions include combustion reactions and the reaction between acid and base to produce salt and water.
