Identify the process in which the cell strives to maintain dynamic equilibrium:
homeostasis
turgor pressure
cytolysis
plasmolysis
Answer:
homeostasis
Explanation:
Homeostasis refers to the ability of the cell to keep a constant and stable environment. This includes chemical, physical, and biological components.
Cells need to regulate their environment despite the conditions outside of the cell. They need to be able to quickly adapt to changes to avoid harm to the cell.
is this physical or chemical change Using a mortar and pestle, you grind up a substance into a fine powder.
Answer:
Physical Change
Explanation:
It's a physical change because nothing is happening to the substance, you're just change the shape/form.

Many coniferous forests containing pine trees grow in the taiga, the largest habitat in the world. Using credible sources, such as NASA, research the typical climate conditions in coniferous forests. Explain why the structure of pinecones helps ensure successful reproduction in coniferous forests.
Answer:
Precipitation in coniferous forests varies from 300 to 900 mm annually, with some temperate coniferous forests receiving up to 2,000 mm/ year (79 in/year). The amount of precipitation depends on the forest location. In the northern boreal forests, the winters are long, cold and dry, while the short summers are moderately warm and moist. In the lower latitudes, precipitation is more evenly distributed throughout the year.
The climate conditions of coniferous trees normally have summer temperatures that range from -40°F to 68°F with seasons ranging with an average of cold, long, snowy winters, and warm, humid summers. With defined 4 seasons, and at least 4-6 frost-free months. The precipitation has about 12 to 35 inches of rain each year. The in these areas of course the vegetation they have is coniferous trees, but the main dominant trees are pines, spruces, firs, and larches. With mosses, liverworts, and lichens covering the main ground.

Your task is to decide which dig site is most likely to produce Dimetrodon fossils. What kinds of information do you think would be most useful for making your decision?
To uncover Dimetrodon fossils, researchers must first research the dimetrodon's habitats, then go to modern-day replicas of those past ecosystems.
Dimetrodon fossils:Because its remains have been discovered in Texas and Oklahoma in the United States, Nova Scotia, Canada, and all throughout Europe, the Dimetrodon is likely to have been well suited to a broad range of environments.
The first fossil was discovered in the nineteenth century, and Edward Drinker Cope named it in 1878.

What is the evidence scientists have to support endosymbiosis and the evolution of prokaryotes to eukaryotes?
Answer: The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.

Explanation:
People's choices can have a positive or negative effect on their health. Describe one positive choice and one negative health choice a person could make. Be sure to explain how each could impact an individual's health and, if applicable, the health of others.
Answer: One positive is they can eat whatever they want, whenever they want. (If they have money) a negative also since people have the freedom to choose what they eat it can impact on their health.
Explanation: Positive Explanation: if someone wanted to have a good cake every once in awhile they can, because no one is telling them not to(unless they don't have money, or is dietbet/on a diet.)
Negative: Since people are eating whatever they want they can CAUSE SERIOUS HEALTH PROBLEMS, causing you to be diabetic, have cancer, poor exercise also can lead to not be able to walk everyday, being unable to walk, can lead to early death. It could affect others because they'll be worried about you, maybe even have to pay for your house bill because you can't work. problems can lead up to more problems.
One positive choice someone can make would be drinking more water. One negative choice someone can make would be smoking too many cigarettes. Drinking more water can boost your health by decreasing chances of digestive problems and increasing blood pressure. Also, smoking too many cigarettes can lead to heart diseases, lung diseases, and diabetes.

Diabetes is often suspected when glucose shows up in urine tests. Use the model to explain how glucose could be present in urine. Why do you think this symptom is especially concerning for young people?
Answer:
S.A for Edmentum and Plato
Like and Rate
In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.

What kind of rays are produced when a metal, such as tungsten, is bombarded with
electrons moving with very high velocities?
a. x-rays
b. gamma rays
c. cathode rays
d. infrared rays
Answer: x-rays
Explanation: When the electrons from the filament strike the tungsten target, x-rays are created photons are created if they either hit a target nucleus directly (rare) or their path takes them close to the nucleus. If a high- speed electron hits the nucleus of a target atom, all its kinetic energy is transformed into a single x-ray photon.
Answer:
X-rays

Diffusion is an important process in animals and plants.
The movement of many substances into and out of cells occurs by diffusion.
Describe why diffusion is important to animals and plants.
In your answer you should refer to:
• animals
• plants
• examples of the diffusion of named substances.
Answer:
Diffusion helps animals in respiration. The cells in an animal's body need glucose and oxygen for respiration. Both these are carried in the blood. When blood reaches the cells the molecules of glucose and oxygen diffuse out of the blood and into the cells. As cells use up the glucose and oxygen they produce waste chemicals and carbon dioxide.
Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. This helps the plants to photosynthesize and produce more food.
Example for animals: Animals using glucose and oxygen in diffusion.
Examples for plants: Plants using carbon dioxide to photosynthesize.

Which of the following is NOT found in the cell membrane:
Nucleic acids
Cholesterol
Proteins
Galactose
Phospholipids
Answer:
nucleic acid are not found in the the cell membrane.
Explanation:
They are only found in ribosomes and the nucleus as either DNA or RNA
Answer:
[tex]\boxed {\tt Nucleic \ Acids}[/tex]
Explanation:
Nucleic acids are the monomers of genetic material, such as DNA and RNA. These structures are found in the nucleus and ribosomes because DNA is stored in the nucleus, RNA is made in the nucleus, and RNA is used to make proteins in the ribosome.
Cholesterol, proteins, galactose, and phospholipids are all cell membrane components. Nucleic acids are not. We know they are in the nucleus and ribosomes. Therefore, the correct answer is nucleic acids.

Why does DNA need to be extracted from a cell before it can be analyzed?
Answer:
to study the genetic causes of disease and for the development of diagnostics and drugs.
Explanation:
It is important to extract DNA from a cell in order to study the genetic causes of disease and for the development of diagnostic and drugs. Scientists will use a cell culture system, which is cells from an organism that have either been made to continuously proliferate (grow) or are cancerous in nature (from cancer).
These cells allow us to continue working on experiments where we can change the conditions to determine various cell functions.
prokaroytic and eukarayotic cells
Answer:
A prokaryote is a cellular organism that lacks an envelope-enclosed nucleus. The word prokaryote comes from the Greek πρό and κάρυον. In the two-empire system arising from the work of Édouard Chatton, prokaryotes were classified within the empire Prokaryota.Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals. These organisms are grouped into the biological domain Eukaryota.
