Bears stop coming to a river ecosystem where they have been eating many fish each day. The fish the bears eat
normally eat smaller fish, which eat plants along the river bottom
What happens to the ecosystem?
The larger fish population will drop first and the smaller fish population will grow quickly. The plants will
die off because too many of the smaller fish are eating them
The smaller fish population begins to eat more plants and to grow. The larger fish have more food to
eat so their population is able to grow, too.
The larger fish population explodes at first, and the smaller fish population begins to drop. Eventually
the river runs out of smaller fish so larger fish die out, and the plant population grows.
Both the larger and the smaller fish populations grow quickly but then die out because the plant life is

Hi,
I don't undestand how epidemiology, through targeted studies, has made it possible to make public health choices to fight cancer. In particular why there is systematic screening for breast, prostate or colon cancer but not systematic for the pancreas, testicle, bladder, etc.
Thanks in advance !
Answers
Epidemiology is the study of patterns, causes, and effects of health and disease conditions in populations. Through targeted studies, epidemiologists have identified risk factors for various types of cancer, which has led to the development of screening programs and other public health interventions.
Breast, prostate, and colon cancer are among the most common types of cancer and have well-established screening programs in place. This is because these types of cancer have a relatively high incidence rate, and screening tests are effective in detecting early stages of the disease when treatment is most effective. In addition, there are well-established risk factors for these types of cancer, such as age, family history, and lifestyle factors like diet and physical activity.
In contrast, screening for other types of cancer, such as pancreatic, testicular, and bladder cancer, is not as systematic. This is because these types of cancer have a lower incidence rate, and screening tests are less effective in detecting early stages of the disease. For example, pancreatic cancer is often diagnosed at an advanced stage because symptoms do not appear until the disease has progressed. Testicular cancer is relatively rare, and self-examination is often effective in detecting early signs of the disease. Bladder cancer is often diagnosed after symptoms appear, but there is ongoing research into the effectiveness of screening tests for this type of cancer.
In addition to incidence rates and screening effectiveness, other factors that influence public health choices for cancer prevention and control include cost-effectiveness, access to healthcare, and potential harms associated with screening tests. For example, some types of cancer screening tests, such as mammography for breast cancer, can lead to false-positive results and unnecessary follow-up procedures, which can cause anxiety and additional costs.
In summary, epidemiology has played a crucial role in identifying risk factors for various types of cancer, which has led to the development of screening programs and other public health interventions. The choice to implement systematic screening for breast, prostate, and colon cancer is based on a combination of factors, including incidence rates, screening effectiveness, cost-effectiveness, access to healthcare, and potential harms associated with screening tests.

Phagocytes are a type of immune cells that specialize in engulfing and digesting foreign particles, such as bacteria, viruses, and cellular debris. The two phagocytes are Neutrophils and Macrophages.
Neutrophils are a type of white blood cell and are the most abundant phagocytes in the bloodstream. They are quick to respond to infections and are often the first immune cells to arrive at the site of an infection. Neutrophils engulf and destroy pathogens by a process called phagocytosis.
Macrophages are a type of white blood cell that is present in various tissues and organs of the body. They are highly specialized phagocytes and play a crucial role in engulfing and eliminating foreign substances. Macrophages not only participate in immune responses but also contribute to tissue repair and maintenance.

The fictional creature shown above has three pairs of chromosomes. On these chromosomes are the genes for wings (or
winglessness), legs (or leglessness) and arms (or armlessness). Please number and answer the following five questions based on
the information in the picture.
1. Which trait is dominant wings or winglessness? How do you know?
2. Which statement is more likely? Make a claim, and back it up with the science of how genes work.
a. The protein product of the wings allele causes the dragon to have wings.
b. The protein product of the wingless allele causes the dragon to be wingless.
Answers
Wings exhibit dominance over winglessness. This conclusion is drawn from the fact that the winged dragon possesses two copies of the wing allele, while the wingless dragon harbors two copies of the wingless allele. Consequently, the manifestation of the dominant allele (wings) prevails, overshadowing the presence of the recessive allele (winglessness).
What are genes?Genes represent the fundamental elements of inheritance. They consist of DNA, a molecular structure that encompasses the blueprints required for protein construction. Proteins undertake the crucial role of executing cellular and tissue functions.
The statement that holds greater plausibility is option A: The protein product of the wings allele causes the dragon to have wings.
This proposition stems from the understanding that genes serve as the blueprint for synthesizing proteins, which in turn carry out vital cellular and tissue functions. In this particular scenario, the protein generated by the wings allele takes charge of wing development in the dragon.

Answers
The brain and spinal cord are part of the central nervous system.
The electrical charges that act as nervous signals are called action potentials or nerve impulses.
Jellyfish do not have a brain. Instead, their nervous system is called a nerve net.
After nervous systems began to develop in bilaterally symmetric animals, some developed ventral nerve cords, while chordates developed dorsal nerve cords.
Skeletons that allow for movement by using muscles and squeezing liquid to change the body shape are called hydrostatic skeletons.
Exoskeletons do not grow with arthropods, and so occasionally must be shed and regrown from chitin.
Muscles move endo- and exoskeletons by contracting and relaxing.
Fertilization is the joining of two gametes called sperm and egg.
A fish that lays her eggs in a cluster is initiating cluster or mass fertilization.
Amniotic eggs are an adaptation by reptiles to allow for reproduction and embryo development on land.
Describe three different strategies used by three different animals to thermoregulate.
Elephants: Elephants thermoregulate by using their large ears as cooling devices. They flap their ears to increase surface area and enhance heat loss through evaporative cooling.Desert Lizards: Desert lizards employ behavioral thermoregulation by basking in the sun to absorb heat and warming their bodies. They also retreat to shade or burrows to avoid excessive heat when needed.Penguins: Penguins have a unique thermoregulation strategy. They huddle together in large groups to conserve body heat and shield themselves from the cold Antarctic winds, effectively reducing heat loss and maintaining body temperature.If you see a snake coiled up in a sunny patch of grass, what can you probably conclude about the type of thermoregulator it is. Why?
If you see a snake coiled up in a sunny patch of grass, you can probably conclude that the snake is an ectotherm. Ectotherms rely on external heat sources, such as the sun, to regulate their body temperature. By basking in the sun, the snake absorbs heat, which helps raise its body temperature to a suitable level for proper physiological functioning.
Answer:
1. central
2. action potential
3. nerve net
4. dorsal
5. hydrostatic
6. Exoskeletons
7. contraction/contracting
8. Fertilization
9. external fertilization
10. Eggs
11. Animals with fur thermoregulate by panting. Winged birds will flap against their mouths/heads to dissipate heat. Humans will produce sweat to evaporatively cool. Polar bears have developed blubber. Bears drop body temperatures during hibernation.
12. Seeing a snake using the warmth of the sun leads us to conclude that it is likely a thermo conformer that cannot produce its own body heat.

What physical property allows a substance to trap heat and keep it from transferring as quickly
A conductor like wood
A insulator like wood
A conductor like metal
A insulator like metal
Answers
A conductor like metal is the physical property which allows a substance to trap heat and keep it from transferring as quickly and is denoted as option C.
What is a Conductor?This is referred to as substance which allows the flows of electrons and heat to pass through it easily. Conductors are mainly metals and examples include Iron, Copper etc ad they are used in the transmission of electricity due to these property.
Insulators on the other hand are materials which don't allow the flow of electrons and heat easily and examples include non metals such as wood, plastic etc.
A conductor like metal will therefore ensure that heat is kept and not transferred quickly which is therefore the reason why option C was chosen as the most appropriate choice.
