Answer: The independent variable of the lab is the type of food that is available to the birds. The food type changes in a given environment, then the amount of each type of bird beak will changes as birds with beaks more suited to the available food will consume more successfully over time.
Explanation:
With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.
What are different types of bird beaks?There are many types of beaks in birds, some of these can be:
Crushing beak.Curved beak.Piercing and tearing beak.Birds of prey.Stickybeak.With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.
Thus, this is the hypothesis which support the given scenario.

the DNA is tightly wrapped around histone proteins in a chromosome why is this packaging necessary?
1. Because the dna molecules will down without it .
2. Because the dna molecules will dissolve in cell water .
3.) because the long dna will fit inside the cell.
4.) because the dna needs to attach itself to support .
Answer:
3.) because the long dna will not fit inside the cell.
Explanation:
This question is oddly written. At first glance, I can tell it's not 1 or 2 because DNA doesn't "dissolve" in cell "water", nor will it "down" (I'm assuming this means "drown"?).
The main reasons for DNA packaging are so that the DNA can fit into the cell, and so it's protected from damage. The DNA is vital to the cell, so it protects it by coiling it up. Coiling and packaging are also important when it comes to gene expression.

Describe the concept of natural selection. Be sure to include contributing scientists and their contributions.
Answer:
Natural selection is the process in which survival of the fittest, a concept by Charles Darwin suggests that animals adapt to better suit their needs. Those who survive are the "fittest" and breed children with the trait until the unfit die out. He saw this with the Galapagos finches. there used to be 1 kind of finch, now there are 14.

Vaccines have been subjected to quite a bit of controversy in recent years. Currently, the Centers for Disease Control and Prevention (CDC) recommend that healthy people receive a flu vaccine every year. What are your current perceptions of the flu vaccine? Do you think these recommendations are appropriate? Explain your reasoning.
Answer:
There are many reasons to get an influenza (flu) vaccine each year.
Flu vaccination can keep you from getting sick with flu.
Flu vaccination can reduce the risk of flu-associated hospitalization for children, working age adults, and older adults.
Flu vaccination is an important preventive tool for people with chronic health conditions.
Flu vaccination helps protect women during and after pregnancy.
Flu vaccine can be life-saving in children.
Flu vaccination has been shown in several studies to reduce severity of illness in people who get vaccinated but still get sick.
Getting vaccinated yourself may also protect people around you, including those who are more vulnerable to serious flu illness, like babies and young children, older people, and people with certain chronic health conditions.
Explanation:
Influenza is a potentially serious disease that can lead to hospitalization and sometimes even death. Every flu season is different, and influenza infection can affect people differently, but millions of people get flu every year, hundreds of thousands of people are hospitalized and thousands to tens of thousands of people die from flu-related causes every year. An annual seasonal flu vaccine is the best way to help protect against flu. Vaccination has been shown to have many benefits including reducing the risk of flu illnesses, hospitalizations and even the risk of flu-related death in children.
Flu vaccines helps to reduce the risk of flu-associated illness. And the recommendations made by CDC that healthy people receive a flu vaccine every year is appropriate.
What is flu?"Also called influenza is a viral infection which can be deadly in high risk groups."Flu symptoms include- fever, cough, cold, fatigue, headaches and muscle pain.It causes asthma, pneumonia and chronic diseases.What is flu vaccines?"These are the vaccines that protect against infection by influenza viruses."What is CDC?"It is the National public health agency of the United States."Hence, in order to reduce the disease caused by flu, it is recommended to receive a vaccine.

8. Ligaments are strips of tough tissue that
support soft tissues inside bones
prevent friction between bones
connect bones to bones
attach muscles to bones
Answer: C
Explanation:
Ligaments are strips of tough tissues that serves as connective tissue for two or more bones and cartilages. These also holds the joints together.
Ligaments are strips of tough tissue that connect bones to bones; that is the third option because the bones that are present in the body are connected to each other with the help of the ligaments.
What is the significance of the ligament?Ligaments are significant for many different factors, such as that they have an important role in physical activities such as sports and maintain optimal performance and injury prevention as they have a rich blood supply. They have an important role in preventing injuries to joints and bones as they protect bones and cartilage from excessive stress and connect bones to bones.
Hence, ligaments are strips of tough tissue that connect bones to bones; that is the third option because the bones that are present in the body are connected to each other with the help of the ligaments.

if a disease killed all the seagulls what effect would this have on the food web?
Answer:
if the disease kills all the seaguells then it will affect the food chain negativleyy because the population of the species that would eat them (predator) will decrease dramatically and the fish ( what the seaguells eat ) there peopulation will increase dramatically because they are not being eaten .
Explanation:
hope this helps , sorry middle school was a long time ago for me : )
Answer and explanation: it would mean that there would be an increase of fish which is what seaguls eat but a decrease of, for example, leopard seals because if there aren't enough seagulls the leopard seals would die of starvation which would then again decrease another animal species because there aren't enough leopard seals. This would then repeat itself again and again.

How would the quantity of stomata compare between plants in tropical environments and plants in hot, arid climates? -Plants in tropical climates would have fewer stomata because they would need to prevent the absorption of too much water from the atmosphere. -Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves. -Plants in hot, arid climates would have more stomata because they would need to release heat from the leaves to prevent dehydration. -Plants in tropical climates would have more stomata because they would need to absorb more water from the air than plants in arid climates.
Answer:
-Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves.
Explanation:
I took the test and got this right.
The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata. So, the correct option is B.
What is Stomata?The little apertures known as stomata are found just on epidermis of leaves. Stomata are visible under a light microscope. Stomata can be found on the stems and other portions of various plants. In exchange of gases and photosynthesis, stomata are crucial.
Because they need to take in more airborne water than plants in arid areas, tropical plants would have more stomata. Since they must prevent unwelcome moisture loss from plant leaves, plants in warm, arid climates would develop fewer stomata. The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata.
Therefore, the correct option is B.
