25 PTS MIGHT GIVE BRAINLIEST Imagine that you are a grain of pollen on a flower that cross-pollinates
the flower of another plant of the same species. Write a journal
entry in complete sentences describing your journey. Correctly
include each of these terms in your entry: pollinator,
pollen, pistil, stamen, anther, stigma, ovary, and eggs
Answer:Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
Explanation: i hope this can give you a little push!
Answer:
As a grain of pollen on a flower, I am responsible for cross-pollinating the flower of another plant of the same species. I began my journey on the stamen of one flower, where I picked up the pollen from another. I was carried to the pistil of the next flower and deposited the pollen on the stigma. I then traveled down the style to the ovary, where I fertilized the eggs, commencing the production of the next generation of this flower.

Explanation:
A scientist studies a dragonfly species. She started with two parent dragonflies and has raised many generations. All have had four wings. In the most recent generation of dragonfly offspring, one dragonfly had eight wings. What do you think caused this change? Identify if the change is helpful, harmful, or mutual and provide an explanation for your choice.
Answer:
Robux
Explanation:
What could of caused this is that the dragonflies with 4 wings, weren't strong enough with flying and needed 4 more, or this could of also been caused with a mutation in the DNA and overtime the mutation has kind of just been a new addition to the dragonfly.
MYTH
Tigers and Goldfish are not related.
FACT
Evidence #1
Evidence #2
Answer:
Yea
Explanation:
The relation between the tiger and the goldfish is that they are both animals that fall into the category of vertebrates. This means that both creatures have spines, and internal bone structure. This is a trait that distinguishes them from the invertebrates that have no spine and bone structure, like the octopus for example, or from the creatures that have an exoskeleton, which means they have a bone structure that is covering the body, but not inside the body itself, like the scorpions for example.
The idea of GMO sounds really good. Why might someone be opposed to making healthier food that lasts longer or doesn't need pesticides?
Answer:
Explanation:
Genetically engineered foods are inherently unstable. Each genetic insertion creates the added possibility that formerly nontoxic elements in the food could become toxic.
Genetic engineering can also alter the nutritional value of food.
Another hidden risk of GE foods is that they could make disease-causing bacteria resistant to current antibiotics, resulting in a significant increase in the spread of infections and diseases in the human population.
Answer:
Many people believe that GMOs are bad for their health – even poisonous – and that they damage the environment.
Explanation:
Moreover, most GM crops are either bred to withstand chemical pesticides or developed to generate insecticides themselves. When herbicides are applied on resistant crops, the weeds acquire resistance over time, necessitating the use of even more chemicals. Crops genetically modified to generate pesticides, on the other hand, create poisons that are toxic not just to pests but also to other insects such as butterflies, moths, and insect pollinators.
Why is part of the Moon dark?
Answer:
because the moon rotates along with the earth so one part remains out of our sight.
Explanation:
List the 3 names of the 3 inputs of photosynthesis using the chemical formulas
6CO2 + 6H2O → C6H12O6 + 6O2
Explanation:
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

Which effect does an ocean have on the climate?
Responses
There is no influence on climate from an ocean.
Rushing water from tides cools the land.
Cool ocean air causes a cool climate.
Warm ocean air causes a dry climate.
The ocean warms and cools more slowly than the atmosphere, thus coastal weather tends to be more moderate than continental weather, with fewer hot and cold extremes. Evaporation from the ocean, especially in the tropics, creates most rain clouds, influencing the location of wet and dry zones on land.
Answer:
Cool ocean air causes a cool climate and warm ocean air causes a dry climate
Explanation:
The ocean warms and cools more slowly than the atmosphere, thus coastal weather tends to be more moderate than continental weather, with fewer hot and cold extremes. Evaporation from the ocean, especially in the tropics, creates most rain clouds, influencing the location of wet and dry zones on land.
Which of these factors is involved in earthquake formation?
Answer:
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other.

What is not a part of the immune system?
A Mucous membranes
B Liver
C Skin
D Saliva
Answer : B
Explanation:
The liver is not a part of the immune system. The liver is an organ that plays a crucial role in detoxifying the body, producing bile to help digest fats and storing nutrients. While the liver indirectly supports the immune system by removing toxins from the bloodstream, it is not a part of the immune system itself.
Answer:
B. liver
Explanation:
The immune system is a complex network of organs, tissues, cells, and molecules that work together to defend the body against harmful pathogens, such as bacteria, viruses, fungi, and parasites.
A Mucous membranes: Mucous membranes are part of the immune system as they serve as a physical barrier that helps to trap and prevent pathogens from entering the body. They are found in various areas of the body, including the respiratory tract, gastrointestinal tract, and urogenital tract, and are lined with special cells that produce mucus and immune cells that help fight against pathogens.
B Liver: The liver is not directly part of the immune system. It is primarily responsible for detoxification, metabolism of nutrients, and production of important proteins, such as clotting factors. However, the liver does play a role in the immune response by filtering blood and removing pathogens, toxins, and other harmful substances from circulation.
C Skin: The skin is the body's largest organ and serves as a physical barrier against pathogens, preventing them from entering the body. Additionally, the skin contains specialized immune cells that help defend against pathogens that may breach the skin's barrier, making it an important part of the immune system.
D Saliva: Saliva, which is produced by salivary glands in the mouth, contains enzymes that can help break down food and also has antimicrobial properties that can help inhibit the growth of bacteria and other pathogens in the mouth. While saliva has some immune properties, it is not considered a primary component of the immune system.
Think about a lake. Would you describe it as a homogeneous mixture, a heterogeneous mixture, or both? Explain.
Answer:People often visualize a lake as a uniform mass of water, almost like a full bathtub that is evenly mixed from top to bottom, side to side and front to back.

A pedigree chart is used to _______.
predict percentage of offspring with a trait
predict genotypic probabilities
track inherited traits through generations
identify the genotype of parents
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.

Explanation:
The Florissant Fossil Beds in Colorado are home to several massive redwood stumps that were subjected to a special kind of fossilization millions of years ago. What service could these fossilized stumps most likely provide? (Worth 15 points)
Please answer ASAP
1. tourism
2. shelter
3. lumber
4. soil creation
The most likely service that these fossilized stumps could provide is tourism. Since they are rare and significant specimens of ancient plant life, they attract visitors from all over the world who are interested in paleontology and natural history. While they may have been useful for lumber or shelter in the past, they are now protected as part of a national monument and cannot be harvested or used for those purposes. As for soil creation, while the presence of the stumps and associated plant and animal fossils can provide insights into past ecosystems and environmental conditions, they do not actively contribute to the creation of new soil.
