if you start near the north pole and head south to the equator what biomes would expect to come across
You need to probably cross tundra and taiga.
What are biomes?The definition of a biome is "the world's principal communities, categorized according to the prevalent flora and distinguished by organism adaptations to that particular environment" (Campbell 1996).
It is impossible to overstate the significance of biomes. Over the course of life on Earth, biomes have evolved and shifted quite a bit. Human activities have significantly changed these communities more recently.
Particularly in Latin America, clearcutting for industrial use or cattle ranching, slash-and-burn farming, and other human activities have resulted in the destruction of tropical forests.
These events are a result of our rising demand for meat products. This damage has been happening quickly for years. Tropical forests that once covered much of the planet are already extinct.
Therefore, You need to probably cross tundra and taiga.

how does studying earths rocks and meteorites support the age of earth?
Answer:
Thousands of meteorites, which are fragments of asteroids that fall to Earth, have been recovered. These primitive objects provide the best ages for the time of formation of the Solar System. There are more than 70 meteorites, of different types, whose ages have been measured using radiometric dating techniques.
Meteorites that fall to Earth represent some of the original, diverse materials that formed planets billions of years ago. By studying meteorites we can learn about early conditions and processes in the solar system's history.
Umm.. maybe my answer is not what you needed
I'm sorry ❤️
Answer:
Scientists think that meteorites can get chemicals such as isopropyl cyanide from a space cloud. So, it’s possible that a meteor that had acquired isopropyl cyanide struck Earth and brought life to the planet.

22) Give an example of the three different types of population dispersion that are not
from the text.
Answer: The dispersion can be defined as the development of spatial relationship between the members of the population in a habitat.
Explanation:
Uniform dispersion: This can be observed in case of plants which secrete toxins which kill the nearby plants hence, reduces the competition for resources. For example, the Salvia leucophylla is responsible for secreting the toxins to kill the neighboring plants.
Random dispersion can be defined as the dispersion in which the plants that disperse their seed by wind but the seeds only germinate in the favorable environment.
Clumped dispersion can be defined as the dispersion in which the seeds are dropped into ground directly. Like in oak trees.

ADP is a molecule related to the energy-storing ATP and it is repeatedly regenerated back into ATP by having a phosphate group added to it.
- True
- False
Answer:
True
Explanation:
ADP is when ATP loses a phosphate group
It is true that ADP is a molecule related to the energy-storing ATP and it is repeatedly regenerated back into ATP by having a phosphate group added to it.
ADENOSINE TRIPHOSPHATE (ATP):
Adenosine triphosphate also known as ATP is a biological molecule that stores and releases energy for use in living cells. ATP stores energy in its phosphoanhydride bonds that holds its constituent phosphate groups together. This energy is released for use during phosphorylation when one phosphate bond is broken to form ADP molecule (adenosine diphosphate). Therefore, it is true that ADP is a molecule related to the energy-storing ATP and it is repeatedly regenerated back into ATP by having a phosphate group added to it.Learn more at: https://brainly.com/question/3194235?referrer=searchResults

Endocrine cells make hormones to send messages from one cell to another. Some of the messages they send are certain types of proteins. These proteins need to be able to travel out of the cell to get to other cells. What part of the cell will make sure the protein signals will be ready to leave the endocrine cells? *
Answer:
The Golgi apparatus is especially developed in cells that have functions related to the secretion of substances, such as cells of the nervous or endocrine system.
Explanation:
The Golgi apparatus is the organelle responsible for most of the modifications that lipids and proteins undergo once their synthesis in the endoplasmic reticulum (ER) has been completed, that is, the Golgi apparatus is a cellular organ whose function is to manage the proteins synthesized by the endoplasmic reticulum in order to transform and export them to the rest of the body. It is made up of flattened cisterns (middle zone) with an entrance zone or face and an exit zone. The proteins enter the Golgi apparatus and are later transported to these cisterns where they are modified by enzymes.

How Is the Earth Changing? How would you answer this question now?
Answer: Climate change
Answer:
Humans—more specifically, the greenhouse gas (GHG) emissions we generate—are the leading cause of the earth's rapidly changing climate. Greenhouse gases play an important role in keeping the planet warm enough to inhabit. But the amount of these gases in our atmosphere has skyrocketed in recent decades. Global sea level rise is complex as well. To begin with, it has multiple causes, including the thermal expansion of the ocean as it warms, runoff of melt water from land-based ice sheets and mountain glaciers, and changes in water that’s stored on land. These factors combine to raise the height of our global ocean about 3.3 millimeters (0.13 inches) every year. That rate is accelerating by another 1 millimeter per year (0.04 inches per year) every decade or so.
Explanation:
identify three environmental conditions that increase the rate of transpiration in plants and explain how they operate
Explanation:
Light
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf.
2. Temperature
Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises. At 30°C, a leaf may transpire three times as fast as it does at 20°C.
3. Humidity
The rate of diffusion of any substance increases as the difference in concentration of the substances in the two regions increases.When the surrounding air is dry, diffusion of water out of the leaf goes on more rapidly.
4. Wind
When there is no breeze, the air surrounding a leaf becomes increasingly humid thus reducing the rate of transpiration. When a breeze is present, the humid air is carried away and replaced by drier air.
5. Soil water
A plant cannot continue to transpire rapidly if its water loss is not made up by replacement from the soil. When absorption of water by the roots fails to keep up with the rate of transpiration, loss of turgor occurs, and the stomata close. This immediately reduces the rate of transpiration (as well as of photosynthesis). If the loss of turgor extends to the rest of the leaf and stem, the plant wilts.
The volume of water lost in transpiration can be very high. It has been estimated that over the growing season, one acre of corn (maize) plants may transpire 400,000 gallons (1.5 million liters) of water. As liquid water, this would cover the field with a lake 15 inches (38 cm) deep. An acre of forest probably does even better.
Why Photosynthesis is so important for a plant to survive?
Answer:
Photosynthesis is important because plants ant just survive on water,just like you and I cannot survive on just plain water. They need food, and as most plants don’t have mouths to get nutrients, they use chloroplasts in their cells to absorb sunlight and get the nutrients the need from degenrating the sunlight into different atoms and compounds. That is also why plants are always a certain color or two. Because sunlight is actually all of the colors, but when a plant absorbs these rays of sunlight, it will only take what it needs. So when you see a green grass blade, it’s because the plant only needed the other colors out of the sunlght and it is reflecting the green color.

Aquaporins are membrane proteins that span the entire membrane. An aquaporin protein must be able to interact with polar regions that are both extracellular and intracellular as well as polar water molecules moving through it’s core. Additionally, it must be able to interact with the nonpolar phospholipid tails. How is it possible that this protein (a collection of amino acids) can meet all of these requirements?
Answer:
- Proteins have the ability to change their conformation in order to establish multiple types of interactions
- Proteins are macromolecules that are large enough to cross the membrane of biological cells regardless of different regional polarities and they may act as pores through which molecules diffuse.
- Proteins have well-defined domains with amino acid residues whose R-groups contain both polar and nonpolar portions and thereby they interact with surrounding molecules according to their requirements.
Explanation:
Porins are a type of protein that cross the cell membrane and thus act as pores through which molecules can diffuse. Aquaporins are porins that form pores across the cell membrane and allow the transport of water molecules between cells. These proteins consist of six transmembrane α-helices embedded in the cell membrane. Aquaporins have five loop regions that enter and exit the cell membrane, and two of these regions are hydrophobic.
Aquaporins are regarded as membrane proteins which span the entire
membrane and are able to perform the listed functions as a result of the
following:
Proteins are structures composed of amino acids which are able to change
in structure and shape thereby aiding different types of interactions
Proteins are able to cross the membrane of biological cells because they
also act as pores through which materials pass through regardless of the
polarity of the molecules.
They also have polar and nonpolar amino acid properties which help to favor polarity of any type.

How are 3D printers useful in studying evolution
Answer:
They can use these printers to make replica or identical copies of things like fossils. Theses are mostly useful because real fossils are rare so they can still study them without possibly ruining an artifact.
Explanation:
An essential component of evolutionary biology, the relationship between form and function is made possible by biomechanics.
What role of 3D printers useful in studying evolution?These printers can be used to create exact replicas of objects like fossils. These are mostly helpful since actual fossils are uncommon, allowing scientists to research them without risking the destruction of an item.
Here, 3D printing presents a chance to create accurate replicas of complete or individual creatures that can be used to test hypotheses regarding the form and purpose of structures.
Therefore, A type of additive manufacturing known as “3D Bioprinting” or “bioprinting” produces 3D structures that are functional 3D tissues by using cells and biomaterials rather than conventional metals and plastics.
