Plant pollen travels from the stamen to the stigma. Which step comes next in the pollination process?
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.

In a paragraph (at least 6 sentences)- Introduce Water Striders and tell how they are able to walk on water by explaining the relationship between hydrogen bonding, cohesion, surface tension, and buoyancy.
Answer:
Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water.
Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight. The legs of a water strider are long and slender, allowing the weight of the water strider body to be distributed over a large surface area. The legs are strong, but have flexibility that allows the water striders to keep their weight evenly distributed and flow with the water movement. Hydrofuge hairs line the body surface of the water strider.

Read about the life cycle of an apple tree, and think about the role apples play in reproduction. Describe how apples help apple trees to reproduce. In other words, for an apple tree, what is the advantage of producing fruit as opposed to simply dropping its seeds on the ground? ⊄ pls help asap⊅
Answer:
Since the apple is food, animals eat the apple( seed and all) and take a poop in a different area.
Explanation:
Since apple seeds don’t digest easy, it has fresh, fertile ground to grow in.

Your friend shows you the image below and claims that it shows the process of mitosis. why is he or she wrong? (3 reasons)
Answer:
1. The cell splits itself twice
2. 4 resulting sperm cells are made
3. Only half of the DNA is kept per cell
Explanation:
Mitosis only has one diving phase that occurs only on body cells, which makes it have 2 daughter cells. This, on the other hand, has 4 daughter cells. If you notice, after the third set of bubbles, the genome(DNA) is split among 4 cells.

Begin with blood flow in the left ventricle, recognizing how the vena cava, aorta, pulmonary artery and veins, right and left atriums, right and left ventricles, arteries, and veins all contribute to blood flow. Oxygenated and deoxygenated blood should also be described in your blood flow description.
Left ventricle, Aortic semilunar valve, Aorta, Arteries, Capillaries, Veins, Inferior vena cava, Right artrium, Tricupsid valve, Right ventricle, Pulmonary semilunar valve, Pulmonary artery, Lungs, Pulmonary veins ( Right & Left ).
Deoxygenated blood is received from the systemic circulation into the right atrium, it is pumped into the right ventricle whereas, The blood that is returned to the right atrium is deoxygenated while the left atrium receives newly oxygenated blood from the lungs through the pulmonary vein.

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?
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.
Butterflies are often observed in grassy areas with many flowering plants. They have a long thin, structure called a proboscis, which is used to collect nectar from flowers.

B Butterflies would survive well in the new area because trees provide shade for the butterflies.
C Butterflies would not survive well in the new area because they eat food produced by the flowering plants.
D Butterflies would not survive well in the new area because the trees would block the sunlight they need to produce energy.

5. Read the following passage.
A small amount of oil can be used to produce a large amount of energy. Because of this, oil has changed the way we live. Our cities are built for cars, which run on oil in the form of gasoline. People have grown used to the idea of being able to hop in their car and drive anywhere they want, for a relatively low price. And our country has a large network of gas stations already in place to make this possible.
However, there is only so much oil underground. Once we have taken all the oil from underground, it will not be replaced. As oil starts to run out, the price will keep increasing. Also, oil releases greenhouse gases when burned, but that is not the only effect it has on the environment. Drilling for oil is a difficult process and can cause environmental damage. In the drilling area, organisms can lose their homes or be killed. Oil is also drilled offshore, which means it is drilled from the ocean floor. This can cause problems for marine life. One of the worst outcomes is when oil is spilled into the ocean, because this is very difficult or even impossible to clean.
a) Based on this passage, what are the pros and cons of using oil? (2 points)
Think about the good and bad things that the passage mentions.
b) How might society affect science when it comes to developing oil-based technology? (1 point)
Think about concerns or needs people may have.

How does the diaphragm remove air from the lungs?
When the diaphragm pushes upward, it decreases the volume of the lungs, pushing air out.
When the diaphragm pushes upward, it increases the volume of the lungs, pushing air out.
When the diaphragm pulls downward, it increases the volume of the lungs, pushing air out.
When the diaphragm pulls downward, it decreases the volume of the lungs, pushing air out.
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.
