Answer: As in other higher vertebrates, the frog body may be divided into a head, a short neck, and a trunk (see Vertebrates). The flat head contains the brain, mouth, eyes, ears, and nose. A short, almost rigid neck permits only limited head movement. The stubby trunk forms walls for a single body cavity, the coelom.

Natural Selection?
Answers
Answer:
1. While you do inherit certain genes from your mother and father, you will get separate versions of those genes meaning there will be advantages and disadvantages.
2. Charles Darwin, Natural selection explains how the genetic traits of a species may change over time. This may lead to speciation and the formation of a distinct new species.
Explanation:
1. Something that is an advantage towards the person achieving the genes is whether or not that trait is beneficial. For example, your body size can be determined by your mother or father which can lead to negative health or positive health. That can be a disadvantage (shape, being born with asthma, inheriting a mental illness). All can be achieved because of a parent.
2. Charles Darwin and his theory illustrate genes because as a parent hands over a gene during pregnancy it can be altered because it is a different version of that gene and that can lead to different species whether it is visible or not.

As the Colorado River carved the Grand Canyon, the land was split and the sides of the canyon grew farther apart. The population of Abert's squirrels in the area was separated by the widening canyon. Over time, scientists noted differences in the two separate populations, including the color of their fur, their size, and their foraging and feeding behaviors. What will happen to the groups of squirrels if they remain separated? How does this relate to genetic variation?
Answers
The canyon became a geographic barrier separating the forests and squirrels on each rim. One population of squirrels had become two separate populations that could no longer reproduce. According to National Geographic, this type of speciation is allopatric speciation.

Your circulatory system is made up of several parts, including your:
Heart. This muscular organ works to pump blood throughout your body via an intricate network of blood vessels.
Arteries. These thick-walled blood vessels carry oxygenated blood away from your heart.
Veins. These blood vessels carry deoxygenated blood back toward your heart.
Capillaries. These tiny blood vessels facilitate the exchange of oxygen, nutrients, and waste between your circulatory system and your organs and tissues.
Interesting facts about the circulatory system
Your heart pumps about 5 liters of blood per minuteTrusted Source, but it’s only about the size of your fistTrusted Source.
It’s estimated that in a 70-year period, your heart will beat over 2.5 billion timesTrusted Source.
In most adult humans, a normal resting heart rate is between 60 to 100 beats per minuteTrusted Source.
The total length of all of the blood vessels in your body is about 60,000 miles.
Capillaries are your most numerous blood vessels and also the smallest. Red blood cells often have to move through the capillaries in single-file.
Your blood pressure changes throughout the day. It’s lowest when you’re asleep, and it peaks in the middle of the afternoon.
How does it work?
Your circulatory system is vital to your survival. Its function is to distribute blood and other nutrients to all your body’s organs and tissues.
The small blood vessels called capillaries facilitate the exchange of oxygen and nutrients between your blood and the cells in your body. Carbon dioxide and other waste products, which are expelled from your body, are also exchanged via your capillaries. These tiny capillaries are spread throughout your body so that they can reach every cell.
Let’s follow the blood on a simple loop through the circulatory system to see how it works:
Oxygen-depleted blood returns to your heart (the right side) via the veins.
Your heart pumps this blood to the lungs. In the lungs, the blood gets rid of carbon dioxide and picks up fresh oxygen.
Newly oxygenated blood returns to the other side of the heart (the left side), where it’s then pumped into the arteries.
Eventually, the blood enters the capillaries. Here, it releases oxygen and nutrients to your body’s organs and tissues. It then picks up carbon dioxide and other waste products.
The oxygen-depleted blood returns to the heart through the veins, and the cycle begins all over again.
The circulatory system can also respond to various stimuli to regulate the flow of blood. Examples of these stimuli include changes in:
blood volume
hormones
electrolytes
Circulatory system conditions
Below, we’ll explore some of the most common conditions that can affect the health of your circulatory system.
Atherosclerosis
Atherosclerosis is when plaque builds up along the walls of your arteries. Risk factors that can contribute to plaque buildup include:
high blood pressure
high cholesterol
tobacco use
diabetes
an unhealthy diet
low levels of physical activity
being overweight or obese
Atherosclerosis can gradually make the arteries narrower, affecting the amount of blood that can flow through them. Because of this, organs and tissues may not get enough oxygen.
When atherosclerosis affects the arteries of your heart, it’s called coronary artery disease. Other arteries in your body can also be affected as well. This is called peripheral artery disease, which affects how well blood can flow to your legs, feet, arms, and hands.
In some cases, an artery may become completely blocked by plaque or a blood clot. When this happens, a heart attack or stroke can occur.
High blood pressure
Your blood pressure is the force that your blood exerts on the walls of your arteries as your heart pumps. High blood pressure can eventually damage your heart and blood vessels, as well as other organs like your brain, kidneys, and eyes.
Angina
Angina is chest pain that occurs when your heart isn’t getting enough oxygen. It’s often caused by coronary artery disease, which makes the arteries supplying the heart narrower due to plaque buildup.
Arrhythmia
An arrhythmia is an abnormal heart rhythm. When you have an arrhythmia, your heart may be beating too fast (tachycardia), too slowly (bradycardia), or irregularly. It happens due to changes in the heart or its electrical signals.
Varicose veins
Your veins contain valves that help keep oxygen-depleted blood flowing toward your heart. When these valves fail, blood collects in the veins, which can cause them to bulge and become swollen or painful.
Varicose veins most often appear on the lower legs.

Answers
Answer:
Explanation:
fractured bone as the arm is swollen
Bruising can happen with almost any kind of tissue damage, including blood leaking from a broken bone. 1 The bigger the area of bruising, the more likely the damage is deep—possibly bone deep. Broken bones often swell. Swelling can be a sign that it's broken.
it will affect your skeletal system as you are unable to moth that part of your body and it also affect your muscular system as you can move your arm.
Broken bones are one of the most common orthopedic injuries. Fractures require treatment which may be as simple as rest, or as invasive as surgery. There are many factors that must be considered to determine the most appropriate treatment of a broken bone including: Some of the most frequently used fracture treatments are described here
that is most likely nerve damage as there is no bruising and it is numb so here nerve damage will be most logical.
muscular and nervous system as you are unable to feel or move your muscle.
muscle strain as it is when she overexercise her muscle which I sometimes experience at night.
it will most likely affect your muscular system
For immediate self-care of a sprain, try the R.I.C.E. approach — rest, ice, compression, elevation: Rest. Avoid activities that cause pain, swelling or discomfort. But don't avoid all physical activity.
skeletal and muscular, the muscle is swollen and affected by the break in the skeletal system.
A treatment would be icing the forearm, and applying a cast.
Patient 2 has nerve damage
The nervous system is affected by the damage.
A treatment would be managing blood sugar levels because the patient has type 2 diabetes. Nerve pain medication would block pain by the damaged nerves.
Patient C has a muscle sprain because when she ran, she might have stepped incorrectly, straining the muscle.
The muscular system is affected by this.
Cold compressions, keeping the calf elevated and rest.

Plant pollen travels from the stamen to the stigma. Which step comes next in the pollination process?
Answers
Answer:
the next step would be germination.
Explanation:
Step 1: Pollination
In general, male gametes are contained in pollen, which is carried by wind, water, or wildlife (both insects and animals) to reach female gametes. The pollen is deposited on a plant's stigma, which is part of the pistil (the elongated part of a flower extending from the ovary). This process is called pollination.
Step 2: Germination
Within a few minutes, pollen tubes begin growing, or germinating, toward the egg cell. These tubes will provide a path for the sperm carried in the pollen to reach the egg.
Step 3: Penetration of the Ovule
The pollen tubes penetrate the ovule, which contains the female gametes.
Step 4: Fertilization
Sperm travel down the pollen tubes and fertilize an egg. Most angiosperms undergo double fertilization, where both an egg and the polar nuclei in the embryonic sac are fertilized.
Answer:
When a pollen grain moves from the anther (male part) of a flower to the stigma (female part), pollination happens. This is the first step in a process that produces seeds, fruits, and the next generation of plants. The stalk holds the anther and attaches it to the flower. The enlarged basal portion of the pistil where ovules are produced.
Explanation:
When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination. Cross-pollination produces stronger plants.

Answers
Answer: When, the diaphragm pushes upward, it decreases the volume of the lungs, pushing air out.
Explanation:
In exhalation, the diaphragm move upward and the chest wall muscles relax, causing the chest cavity to get smaller and push air out of the respiratory system through the nose or mouth.
When you breathe in, the diaphragm moves downward toward the abdomen, and the rib muscles pull the ribs upward and outward. This makes the chest cavity bigger and pulls air through the nose or mouth into the lungs.
