Which sphere in the Earth system is also part of the hydrosphere? O A. Atmosphere O B. Biosphere O C. Geosphere D. Cryosphere
A. atmosphere
explanation: there is water vapor in the atmosphere that is considered to be part of the hydrosphere.
In an ecosystem, atmosphere is a sphere in the Earth system which is also part of the hydrosphere.
What is an ecosystem?
Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Explanation:
All eukaryotic cells contain at least one Golgi complex, typically located in the cytoplasm and near the endoplasmic reticulum.
Which of the following best describes a process that occurs within the Golgi complex?
Answer: Enzymatic modification of newly synthesized integral membrane proteins
Explanation: got it right for AP Bio.
The correct answer that describes the process that occurs within the Golgi complex is the enzymatic modification of newly synthesized integral membrane proteins.
Once protein is synthesized, they undergo folding and repackaging within the endoplasmic reticulum before they are transported to the Golgi apparatus/complex.
Within the Golgi complex, the protein is modified enzymatically and encased in vesicles. It is then transported to the cell membrane where they are utilized as integral protein.
So, basically, the statement that best describes the process that occurs within the Golgi complex is the enzymatic modification of newly synthesized integral membrane proteins.

Where do tidal bulges form during the New and Full moons?
Answer:
hope it helps..
Explanation:
High and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides.
A change in body temperature will have which of the following effects on enzymes in the body?
A. A temporary change in the ability of some enzymes to bind with their coenzymes
B. A temporary change in the ability of some enzymes to bind with their substrate
C. A temporary reduction in the concentration of some enzymes in the body
D. A temporary increase in the concentration of some enzymes in the body
Pls help. I think it’s either C or D idk and the question is worth a lot of points :(
Answer:
The answer is B :)
Explanation:
A temporary change in the ability of some enzymes to bind with their substrate. The correct option is B.
Thus, Animals can be categorized into two groups: those that keep a steady body temperature despite varying environmental temperatures and those that have a body temperature that fluctuates with the environment.
Ectotherms are animals that do not regulate their body temperature but instead depend on outside energy to accomplish it.
The name "cold-blooded" has been applied to this category, but it might not be appropriate for an animal living in the desert with a fairly warm body temperature. Animals known as endotherms can experience temperature extremes but rely on internal sources to maintain their body temperature.
Thus, A temporary change in the ability of some enzymes to bind with their substrate. The correct option is B.

You are at the zoo and watching a lion chew on some meat. You begin to taunt the lion since he is behind the glass and cannot get to you. He
charges the glass and breaks through. Your adrenaline kicks in and you take off running. What system is repressed during your escape?
Answer:
The parasympathetic nervous system is repressed during your escape.
Explanation:
In the exposed example, during your escape from the lion, the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) system are responsible for your body response. They send signals and release adrenaline and noradrenaline to increase your heart biting frequency, and blood pressure, stimulating your respiration and dilating your respiratory tracts.
Once you manage to escape from the lion, and the threat factor is over, the body gets back to normality. At this point, the parasympathetic nervous system is activated. Your body activities become normal again. Your arterial pressure, respiratory frequency, and cardiac frequency get reduced to their normal conditions. You are relaxed and at rest.
When the parasympathetic system is activated, the sympathetic nervous system is not, as they perform in opposite ways.

Why is oceanic crust younger than continental crust?
Answer:What is the best explanation for why oceanic crust is subducted by continental crust?
The continental crust is also less dense than oceanic crust, although it is considerably thicker. As a consequence of the density difference, when active margins of continental crust meet oceanic crust in subduction zones, the oceanic crust is typically subducted back into the mantle.
Explanation:Why oceanic crust is younger than Continental?
Through mantle convection, the rich minerals of the mantle may be ultimately “recycled” as they surface as crust-making lava at mid-ocean ridges and volcanoes. Largely due to subduction, oceanic crust is much, much younger than continental crustWhy is the theory of plate tectonics so important to geologists?

weight
a.Rickets
b.Bone remodeling
c.Ossification
d.Bone maturation
Answer:
b.Bone remodeling
Explanation:
Bone remodeling is also known as bone metabolism is a process in which bones undergo bone resorption where old or mature bines tissue is removed from the skeleton and ossification (formation of new bone tissue).
Bone remodeling is a lifelong process that is influenced by the growth hormone/IGF-1 system that is stimulated when the body increases in size and weight.
Hence, the correct answer is "b.Bone remodeling".

Answer:
Consumer, predator, and prey.
Explanation:
The snake is a consumer and a predator because it eats or consumes another organism (the mouse), but it is also prey because it is consumed or preyed upon by another predator (the hawk).
The three terms that best describe the snake are consumer, predator, and prey. Thus, the correct option for this question is A.
What is Predator?A predator may be characterized as a type of animal that significantly obtains food by killing and consuming other organisms in the form of food and taking energy for the metabolic processes. These animals hunt and kill other organisms for food. The organisms that are consumed by the predators are known as the prey.
According to the context of this question, when a snake eats a mouse, it is called a consumer and predator because it actually drives energy from the mouse in order to facilitate its metabolic processes. When a hawk when catches a snake and eats it, it is often known as prey, and the hawk is known as a predator in this case.
Therefore, the three terms that best describe the snake are consumer, predator, and prey. Thus, the correct option for this question is A.

Why did life first occur in the oceans and not on Earth’s surface?
Answer:
I think because many more bacteria and cells and etc were first like created in the water, they they developed and made bigger and bigger living organisms
Answer:
Because God decided that he was gonna make animals first and he started with the ocean and then land and sky. He then made Adam to take care of all of the animals. But saw that he was lonely and made Eve with one of his ribs. He then put them in the garden of Eden with a tree that was forbidden to eat from. The tree of knowledge of the good and evil. One day eve was walking by the tree when a serpant asked her why they didn't eat from it. She replied by saying that God asked them to not eat from that tree. The serpant told Eve that God just doesn't want them to be knowledgeable like him. She took a bite of the apple and then gave some to Adam. They then realized that they were naked and made clothing from animal skin. This was what created sin. They tried to hide from God but he already knew and he banished them from the garden with angels and a fire sword at the enterance. He went to the serpant and cursed him for telling Eve to eat from the tree. Adam and Eve went on their way and had 2 boys. Cane and Abel.
Explanation:
Which is denser, 50 mL of water or 500 mL of water?
Answer:
50mL
Explanation:
Density is inversely proportional to volume.
This implies that, for the same mass of water, the higher the volume, the less dense it is.
By comparison 500ml is greater than 50ml
Going by the above analysis, 50ml will be less dense than 500ml because it is smaller.
