Answer:
The pollen grows a tube to the ovary.
Explanation:
After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary. Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules. Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule.
Answer:
The pollen grows a tube to the ovary.

Explain why scientists have hypothesized that modern vertebrates and cephalochaordates eveolved by paedeomophisis.
Answer:
The following section explains the description and as per the given situation.
Explanation:
Throughout the 1920s, Walter Garang proposed whether vertebrates formed from some kind of pedomorphosis simplified such as lava. Garstang mentioned whether attaining sexually mature would just have frozen several tunicates throughout their larval stages at a much more early development stage, in which they'll replicate.This describes the dynamic changes between sedimentary metamorphic and igneous substances
Answer:
This is a solid substance that is composed of minerals. This describes the dynamic changes between sedimentary, metamorphic, and igneous substances. This occurs are mid-ocean ridges where a new oceanic crust is formed and then slowly moves away from the ridge.
Explanation:
The "dynamic changes" between sedimentary, metamorphic, and igneous substances refer to the processes by which these rock types are transformed from one another over time and explain the geological process.
What is the significance of the different rocks?There are different types of rocks, such as metamorphic rocks, which form from the alteration of pre-existing rocks, such as metamorphic rocks, through heat, pressure, etc., and igneous rocks, which form from the solidification of magma or lava. Sedimentary rocks form from the accumulation of sediments, such as sand and gravel, and all these rock types explain the complex geological processes.
Hence, the "dynamic changes" between sedimentary, metamorphic, and igneous substances refer to the processes by which these rock types are transformed from one another over time and explain the geological process.

A small family farm has 230 acres of farmland to grow corn . If each acre yields 63 bushels of corn and each bushel can be sold at $9.00, how much does the farm make corn per year?
Answer:
$130,410
Explanation:
According to this question, a small family farm has 230 acres of farmland to grow corn. Each acre yields 63 bushels of corn i.e 1 acre = 63 bushels of corn
Also, each bushel can be sold at $9.00 i.e. 1 bushel = $9.00
If 1 bushel = $9.00
63 bushels = 63 × 9 = $567
Since 63 bushels of corn = 1 acre, it means that $567 is made on one acre.
Hence, on 230 acres, 230 × 567 = $130,410 will be made on corn per year

3. In the sim molecules moved faster when it was warm and slower when it was cold. This can explain why the food coloring spread faster in warm water because the molecules were moving faster causing the food coloring to quickly spread through out the water.
Sorry if its wrong
The food color mixes more easily with the warm water than with the cold water, as the warm water has less density than the cold water, which allows the diffusion of the color in the water.
What role does food coloring play in the lives of organisms?It has numerous negative effects on the organism, including allergic reactions to certain food coloring, increased hyperactivity in children, disruption of the endocrine system, negative effects on reproduction and development in animals, and so on. Aside from that, the animals may exhibit symptoms of liver and kidney failure due to its toxicity.

What is a protist as in the Protist Kingdom?
Answer:
A protist- is any eukaryotic organism (that is, an organism whose cells contains a cell nucleus) that is not an animal, plant, or fungus.
Explanation:
The protist kingdom comprises unicellular eukaryotes.
What organisms are in the protist kingdom?All living organisms have been divided into two broad groups known as eukaryotes and prokaryotes. This classification is based on the complexity of their cell structures. The prokaryotes lack organelles and a true nucleus while these structures are present in the eukaryotic cell.
Based on this simple parameter, in the Five Kingdom system of classification, unicellular prokaryotes were known as Monera and unicellular eukaryotes were known as Protists.
Therefore, any single-celled organism with a true nucleus and membrane-bound organelles is a part of this kingdom of classification.
Fungi, Plantae and Animalia are other classified kingdoms. They are all multicellular with some exceptions. Fungi are saprophytic, plants are photosynthetic and animals are heterotrophic.
Some examples are amoeba and paramecium.

Consider the contents of your stomach 1 hour after eating this meal. What, if anything, ha been digested? What, if anything, has been absorbed? Constituents What happens to_____ in the stomach? Digested or of food Absorbed? CarbohydratesFatsProteinsVitamins SucroseWater
Answer:
Proteins
Explanation:
Of all the food types, Protein has the shortest digestion process. The digestion and absorption of protein starts in the stomach where protein is converted to amino acids and other polypeptides by the enzyme pepsin and more amino acids are produced in the pancreas by the trypsin. Note that much of these amino acids are not absorbed by the body, they are excreted through the urine as uric acid.

A roller coaster containing four cars is accelerating at -15 m/s2 before it comes to an abrupt stop at the end of the ride. The mass of one car is 200 kg. How much force was exerted on the roller coaster to bring it to a stop
Answer:
F = -3000 N
Explanation:
Given that,
Mass of the car, m = 200 kg
A roller coaster containing four cars is accelerating at -15 m/s²
We need to find the force exerted on the roller coaster to bring it to a stop. Let F is the force.
F = ma
Putting all the values,
F = 200 kg × (-15 m/s²)
= -3000 N
So, the force us 3000 N and it act in opposite direction.
In which of Studies 1 and 2 did some of the fruit flies live for more than 75
days, and what diet were those fruit flies fed?
Study 1; 05% SY medium
O Study 1; 15% SY medium
Study 2:05% SY medium
O Study 2; 15% SY medium
Answer: Study 2: 05% SY medium
Explanation:
The x axis on each graph shows the number of days that has elapsed while the y axis shows the percentage of fruit flies that are still alive. In the Study 1, we notice that all the fruit flies had died off by the 55th day.
In Study 2, we then see that some fruit flies lived past 75 days. Those were fruit flies which had been put in the tube that had only 5% SY medium which contains 5% sugar and 5% killed yeast.

If Adam is walking to his car in the snow and feels himself starting to slip and fall, he is using what sensory pathway to convey this information to the level of his conscious awareness?a. posterior column pathway b. corticospinal pathway c. anterior spinothalamic tract d. lateral spinothalamic tract
Answer: A (POSTERIOR COLUMN PATHWAY)
Explanation: Corticospinal pathways are involved in motor pathway whereas others are involved in sensory. however, lateral spinothalamic pathway carry sensations like pain and temperature.
But,the posterior column and the anterior spinothalamic carries the sensation of touch.
The anterior spinothalamic pathway carries light touch while the posterior column carry deep touch and sensation.
Now from the question,fall and slip vibration and movement brings about the activation of posterior column, However,it carries information to the conscious center of the cerebrum whereas the spinothalamic pathway carries information to the thalamus in the brain.

Which type of dating method can be used on rock layers by applying the law of superposition
Answer:
Relative dating
Explanation:
The Law of Superposition of rocks states that the layer of rock which is below is older than the one above it.
Therefore, the type of dating method that can be used on rock layers by applying the law of superposition is relative dating because it is used when the rocks have been kept in their original sequence and not tampered with.
