Answer:
For instance, prey species have defense adaptations that help them escape predation. These defenses may be mechanical, chemical, physical, or behavioral.
Explanation:
Other types of defense animals can develop are mechanical and chemical defences.
Types of defense mechanism.Defence mechanism are used by various animals to better adapt to their environment and escape from their predators.
The types of defense mechanism include:
Mechanical defences: such as the presence of thorns on plants or the hard shell on turtles, physically prevents the predator from being able to eat the prey.Chemical defenses: Some animals such as the millipede makes a noxious substance that irritates eyes and skin.Physical defences: A typical example is camouflage, which is the ability of organisms to disguise their appearance in order to blend in with their surroundings.Therefore, other types of defenses are mechanical and chemical defences.

if there is 8 g of a substance before a physical change, how much will there be afferwards
Answer:
The correct answer is 8 g.
Explanation:
During a physical change, the identity of the substance does not change, because no chemical reaction occurs. So, after the change, the amount of substance is still the same. Examples of physical changes are changes in the state of matter (solid-liquid-gas). If 8 grams of ice (water in the solid-state) are melted, after the melting process we will have 8 grams of water in the liquid-state, but still 8 grams of water.

Provide an example of how your body could maintain homeostasis in response to detecting that the body temperature was falling below 98.5 degrees.
Answer:
Our body produces heat energy.
Explanation:
When our body temperature decreases than normal range, our body produces heat to maintain internal heat in the normal range. Our internal body temperature is regulated by hypothalamus which is a part of our brain. The hypothalamus regulate the temperature and take actions to maintain it in the normal range of temperature which is about 37°C. If our body temperature is too low, the hypothalamus order to the body to generates heat energy and maintains heat in the normal range. The sweat glands remain inactive in order to prevent heat losses.
Suppose an entire colony of lemmings is chased by a predator and most of them jump off a cliff and perish. Fortunately, a few of them don't jump and re-establish their colony (Re-established Colony) and a few of the jumpers land in the water, survive the fall and establish a second colony on a nearby island (Island Colony). Which of the following characterizes the type of change causing a reduction in the genetic variation that occurs in these 2 colonies?
Answer:
re-established colony is bottleneck effect and island colony is a founder effect
Explanation:
since the re-established colony was created after the death of a large number of lemmings, it was a random event so it is a bottleneck effect. the surviving lemmings that jumped into water made their own, new population, which would be a founder effect
The re-established colony is the result of the bottle-neck effect, while the island colony is the result of the founder effect. In both situations, there will be a reduction in genetic diversity.
What do you mean by Genetic variations?Genetic variations may be defined as the presence of differences in the sequence of genes between individuals organisms of a species.
In an island colony, a founder effect may arise which states that a few individuals of lemmings from a population start a new population with a different allele frequency than the original population.
In the re-established colony, a genetic bottleneck changes the genetic variation, which develops when a population undergoes a drastic reduction in population size.
Therefore, the re-established colony is the result of the bottle-neck effect, while the island colony is the result of the founder effect.

What are prokaryotic cells?A cell type without a genuine nucleus or membrane-bound organelles is referred to as prokaryotic. All the other types of life are eukaryotic, whereas organisms in the categories of Bacteria and Archaea are centered on the prokaryotic cell.
Prokaryotic species, on the other hand, are exceedingly prevalent and account for a large portion of the biomass on Earth.
Unicellular organisms are those that have prokaryotic cells. We refer to them as "prokaryotes." A prokaryotic cell may operate as a live creature thanks to a number of factors. Prokaryotes have a cell membrane covering them at first.
With the help of this membrane, they may engineer a particular environment for metabolic processes within the cytosol. Second, these cells contain both ribosomes and free DNA.
Even though ribosomes are organelles, a plasma membrane does not enclose them.
Therefore the correct option is A.

WHAT IS The 2nd phase of mitosis
Answer:
When prophase is complete, the cell enters prometaphase — the second stage of mitosis. During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles. As a result, the spindle microtubules now have direct access to the genetic material of the cell.

At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.

Different mechanisms of reproduction exist within the same species.
Different metabolic pathways exist within the same species.
Different species have the same genetic code.
Different species have the same number of chromosomes.
Answer:
1. Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.
2. Anabolism & Catabolism
3. Nearly everybody has the same genetic code. Although the sequences of bases in their DNA (and thus in the messenger RNA that is made from their DNA) vary between species and even between individuals within a species, almost all of them use the same code.
4.Yes, two or more species can have the same number of chromosomes. ... There's much more to differentiating between species than number of chromosomes. For one example, there are proteins present on eggs which 'match up' with proteins on sperm, and these are very specific.

It's always a good idea to drink plenty of fluids, especially when you have been exercising. Drinking plenty of water helps to flush away materials that might form kidney stones. Staying hydrated is the best way to prevent kidney stones.
Problems of the Excretory System
3
The urinary system controls the amount of water in the body and removes wastes. Any problem with the urinary system can also affect many other body systems.
Kidney Stones
4
In some cases, certain mineral wastes can form kidney stones (Figure below). Stones form in the kidneys and may be found anywhere in the urinary system. Often, stones form when the urine becomes concentrated, allowing minerals to crystallize and stick together. They can vary in size, from small stones that can flow through your urinary system, to larger stones that cannot. Some stones cause great pain, while others cause very little pain. Some stones may need to be removed by surgery or ultrasound treatments.

What are the symptoms of kidney stones? You may have a kidney stone if you have pain while urinating, see blood in your urine, and/or feel a sharp pain in your back or lower abdomen (the area between your chest and hips). The pain may last for a long or short time. You may also have nausea and vomiting with the pain. If you have a small stone that passes on its own easily, you may not experience any symptoms. If you have some of these symptoms, you should see your doctor.

Kidney failure
7
Kidney failure happens when the kidneys cannot remove wastes from the blood. If the kidneys are unable to filter wastes from the blood, the wastes build up in the body. Kidney failure can be caused by an accident that injures the kidneys, the loss of a lot of blood, or by some drugs and poisons. Kidney failure may lead to permanent loss of kidney function. But if the kidneys are not seriously damaged, they may recover.
8
Chronic kidney disease is the slow decrease in kidney function that may lead to permanent kidney failure. A person who has lost kidney function may need to get kidney dialysis. Kidney dialysis is the process of filtering the blood of wastes using a machine. A dialysis machine (Figure below) filters waste from the blood by pumping the blood through a fake kidney. The filtered blood is then returned to the patient’s body.During dialysis, a patient’s blood is sent through a filter that removes waste products. The clean blood is returned to the body.

Urinary tract infections (UTIs)
9
Urinary tract infections (UTIs) are bacterial infections of any part of the urinary tract. When bacteria get into the bladder or kidney and produce more bacteria in the urine, they cause a UTI. The most common type of UTI is a bladder infection. Women get UTIs more often than men. UTIs are often treated with antibiotics.
10
Most UTIs are not serious, but some infections can lead to serious problems. Long lasting kidney infections can cause permanent damage, including kidney scars, poor kidney function, high blood pressure, and other problems. Some sudden kidney infections can be life threatening, especially if the bacteria enter the bloodstream, a condition called septicemia.
11
What are the signs and symptoms of a UTI?
- a burning feeling when you urinate,
- frequent or intense urges to urinate, even when you have little urine to pass,
- pain in your back or side below the ribs,
- cloudy, dark, bloody, or foul-smelling urine,
- fever or chills.

What happens when plates meet? (4 complete sentences minimum)
Answer:
If two tectonic plates collide, they form a convergent plate boundary. Usually, one amongst the converging plates will move beneath the opposite, a process called subduction. ... The new magma (molten rock) rises and will erupt violently to make volcanoes, often building arcs of islands along the convergent boundary. When two plates are moving far from one another, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the world and erupts to make new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the method of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges aren't as violent as they're at convergent plate boundaries.
