where is the fertilization in plant take place
Answer:
Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. It occurs in ovary of female flower
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.

PLS ANSWER What happens to glucose and oxygen that is produced by plants during photosynthesis?
Answer:
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
Explanation:
(a) Describe the process by which cells produce the FGF5 pre-mRNA , and include the location
where the process occurs.
Answer:
Explanation:
mRNA (messanger ribonucleic acid) is produced through the process called transcription in the nucleus. Transcription make ribonucleic acid from deoxyribonucleic acid. The enzyme RNA polymerase creates an RNA molecule that is complementary to the template DNA coping all the information on the DNA into the mRNA formed and 3' to 5' cap are added to stabilize the RNA after which this mRNA then moves from the nucleus where it was produced to the ribosome in the cytoplasm for translation of the information that is coded in the bases.
FGF5 is a gene that is encoded in the DNA.
mRNA is a messenger molecule, which transcribes the information from DNA and delivers it to the RNA.
Role of mRNA Transcription is the process of decoding the message delivered by DNA into a messenger molecule of RNA. The enzyme RNA polymerase is involved in creating the RNA molecule.
FGF-5 gene is produced in the outer root of the hair follicle and perifollicular macrophages. The mRNA produced is complementary to the template DNA and copied all the information of the DNA.
The mRNA is then capped and sent to ribosomes for further translation. The gene is encoded in the DNA.
Thus, transcription is the process in which the mRNA is complementary to the template DNA strand copying all the information.

What are adaptations and give an example.
Answer:An adaptation can also be behavioral, affecting the way an organism responds to its environment.
Explanation:
An example of a structural adaptation is the way some plants have adapted to life in dry, hot deserts. Plants called succulents have adapted to this climate by storing water in their short, thick stems and leaves.

3. Which feature is commonly formed
at a plate boundary where oceanic
crust converges with continental crust?
(1) a mid ocean ridge (2) an ocean trench (3) a transform fault (4) new oceanic crust
Answer:
2) an ocean trench
Explanation:
Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.
What is Ocean Trench?Long, narrow depressions on the seafloor are known as ocean trenches. These chasms are among the deepest natural places on Earth and the deepest portions of the ocean.
Every ocean basin on the planet has ocean trenches, but the deepest ones encircle the Pacific Ocean as part of the so-called "Ring of Fire," which is also home to active volcanoes and earthquake-prone regions. Tectonic activity, which refers to the movement of the Earth's lithosphere, is what causes ocean trenches.
Ocean trenches in particular are a characteristic of convergent plate borders, which occur where two or more tectonic plates collide. In a process known as subduction, dense lithosphere melts or slides beneath less dense lithosphere along numerous convergent plate borders, forming a trench.
Therefore, Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.

Calculate the number of liters of liquid that are in Lake Erie, which has a volume of 484 cubic km (km3). Express your answer in scientific notation.
Answer: The answer in scientific notation is [tex]4.84\times 10^{14}[/tex]
Explanation:
The conversion factor is : [tex]1km^3=10^{12}L[/tex]
Given : Volume of liquid in Lake Erie = [tex]484km^3[/tex]
To find : Volume of liquid in Lake Erie in units of liters
As [tex]1km^3=10^{12}L[/tex]
Thus [tex]484km^3=\frac{10^{12}}{1}\times 484=484\times 10^{12}L[/tex]
The answer in scientific notation is [tex]4.84\times 10^{14}[/tex]
A student wants to know the effect a mutation might have on a species' survival. The change causes a rabbit to have mottled brown fur. The student runs a computer simulation for ten generations. What possible conclusions can you draw? Choose ALL that apply
Answer:
A) Evolution occurred because the allele frequency changed over time.
C) The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.
E) The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.
Explanation:
Based on the data, you can conclude:
Evolution occurred because the allele frequency changed over time.
The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.
The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.
The possible conclusions that can be drawn are
evolution that occurred due to the allele frequency.Rabbits with mottled brown fur have a selective advantage.The mutation had a positive effect.What is mutation?The mutation is a change in the DNA sequence that results from the copying mistakes that tke place during the cell division and the exposure to the radiating agent, exposure to virus and chemicals also leads to the cases of gene mutation.

What happens during the 4 stages of mitosis
Answer:
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope ...

Enzymes catalyze chemical reactions in the human body. Which statement best describes how enzymes work?
A They speed up chemical reactions by increasing the activation energy.
B They slow down chemical reactions by increasing the activation energy.
C They speed up chemical reactions by lowering the activation energy.
D They slow down chemical reactions by lowering the activation energy.
Answer:
A
Explanation:
Hope this is helpful!!:)
Enzymes work by speeding up chemical reactions through the lowering of the activation energy of the reactants.
In every reaction, reactants need to summon a minimum energy amount before they can get to products. this energy is referred to as activation energy.
When an enzyme is introduced into a reaction, it lowers the activation energy. By doing so, reactants can get to products quicker because the mountain they need to climb has been lowered by the enzyme.
In other words, enzymes create a shorter route for reactants to take towards their destination - products.
