=> It is a component derived from the living part of an ecosystem(A wooden tree), so it is a biotic component.
Which of the following structures would normally be found in a plant cell but not in an animal cell? A. cell wall B. cell membrane C. nucleus D. vacuoles
Answer: A) Cell wall
Explanation:
Please note that because it says normally not in an animal cell, the answer may be vacuole, which are rarely in animal cells. However, because cell walls are never found in animal cells, I went with that.
Hope it helps <3
Answer:
Cell Wall
Explanation:
Animals have only cell membrane due to which they move but Plants have cell wall due to which they don't move
For four o'clock flowers, flower color is a case of incomplete dominance. The gene for flower color has two alleles: red (R) and white (r). What is the percent probability that one offspring from a parent with red flowers and a second parent with white flowers will have the genotype rr? Use a Punnett Square to figure out the likelihood.
Answer:
0%
Explanation:
The question is about a gene coding for flower colour in four o'clock plants. The alleles exhibit incomplete dominance i.e the allele for red color (R) is incompletely dominant over the allele for white color (r), hence, an heterozygous intermediate phenotype, which has a pink color, is produced when both alleles combine i.e. Rr.
A parent with red flowers will possess a genotype: RR while a parent with white flowers will possess a genotype: rr. When both parents are crossed using a punnet square (see attached image), all possible offsprings will possess a pink heterozygous phenotype with genotype Rr.
Therefore, the percentage probability of producing an offspring with genotype: rr is 0% since it is not possible considering the parent's genotypes.

Read the passage from Darwin's journal. These two species of Amblyrhynchus agree, as I have already stated, in their general structure, and in many of their habits. Neither have that rapid movement so characteristic of the genera Lacerta and Iguana. They are both herbivorous; although, the kind of vegetation on which they feed is so very different. Mr. Bell has given the name to the genus from the shortness of the snout; indeed, the form of the mouth may almost be compared to that of the tortoise: one is led to suppose that this is an adaptation to their herbivorous appetites. It is very interesting thus to find a well-characterized genus, having its marine and terrestrial species, belonging to so confined a portion of the world. The aquatic species is by far the most remarkable because it is the only existing lizard which lives on marine vegetable productions. As I at first observed, these islands are not so remarkable for the number of the species of reptiles; as for that of the individuals, when we remember the well-beaten paths made by the thousands of huge tortoises—the many turtles—the great warrens of the terrestrial Amblyrhynchus—and the groups of the marine species basking on the coast-rocks of every island—we must admit that there is no other quarter of the world where this order replaces the herbivorous mammalia in so extraordinary a manner. What differences did Darwin find about the two species? One is fast, while the other is slow. One eats plants, while the other eats meat. One lives inland, while the other lives in the water. One has a long snout, while the other has a short snout.
Answer:
One lives inland, while the other lives in the water.
Explanation:
Amblyrhynchus cristatus is a marine reptile that lives in the Galápagos Islands. This species attracted the attention of Darwin because it is a marine iguana that lives exclusively in the Galapagos and, interestingly, their close relatives inhabit in land, also in the Galápagos Islands. The marine and land iguanas from Galápagos form a phylogenetic clade that is characterized by high diversification levels, which are evidenced by conspicuous phenotypic differences. These species can hybridize with each other, but the offspring are infertile. Recently, it has been shown by using phylogeographic analysis that both species diverged 8-10 million years ago.
Answer:
They both eat plants.
Explanation:
They are both herbivorous; although, the kind of vegetation on which they feed is so very different.

Light-dependent reactions
Light-independent reactions
Sun's energy absorbed
Sugars produced
Answer:
The question is unclear but I suppose we're to match the stage of photosynthesis with it's description below.
Light-dependent reactions- Sun's energy absorbed
Light-independent reactions- Sugars produced
Explanation:
Photosynthetic process involves two main stages viz: light dependent stage and light-independent stage. In the light dependent stage, light energy from the sun is trapped or absorbed by the Chlorophyll pigment of green leaves. The absorbed energy is used to split water in a process called PHOTOLYSIS OF WATER.
This process (photolysis) releases protons that build up in the thylakoid membrane to produce a proton pump that generates ATP. At the end of the light dependent reactions, ATP and NADPH molecules are produced.
In the light independent stage which occurs in the stroma of the CHLOROPLAST, the ATP and NADPH molecules produced in the light stage are used to power and reduce carbondioxide (CO2) to synthesize sugar (glucose).

Which cell organelle is most directly involved with the bonding of amino acids?
A) mitochondrion
B) endoplasmic reticulum C) cell wall
D) ribosome
Ribosome is the cell organelle that is most directly involved with the bonding of amino acids
RIBOSOME:
Ribosome is an organelle found in both eukaryotic and prokaryotic cells. It is the organelle involved with the synthesis of proteins in living cells. This is because the process of translation i.e. synthesis of proteins from mRNA occurs in the ribosome. Proteins are macromolecules formed from the joining together of series of amino acids via a peptide bond. This means that amino acids are bonded to form proteins. Since, ribosomes are the organelles for protein synthesis, hence, it is the cell organelle that is most directly involved with the bonding of amino acids.Learn more: https://brainly.com/question/241631?referrer=searchResults

If the number of photosynthetic organisms on Earth decreased drastically, which would happen as a result? Less water would be available on Earth’s surface. Less solar energy would reach Earth’s atmosphere. More oxygen gas would be found in Earth’s atmosphere. More carbon dioxide gas would be found in Earth’s atmosphere.
If photosynthetic organisms are decreasing on Earth there is no consumption of carbon dioxide, hence option 4 is correct.
How much carbon dioxide Earth’s atmosphere?The amount of oxygen in the atmosphere will likewise decrease as the number of photosynthetic species rises.
More carbon dioxide gas would be found in the atmosphere because forests, especially rainforests, create more oxygen. The development of oxygenic photosynthesis was the most significant metabolic advancement in Earth's history.
It liberated life from the finite supply of reductants drawn from geochemistry and allowed it to create energy and reduce power directly from sunshine and water.
Therefore a decrease in photosynthetic organisms increases the carbon dioxide gas in Earth’s atmosphere.

In an electron microscope, the sample is bombarded with a stream of electrons that are expelled from an electron gun. The electrons interact with the sample component, the result of which is transformed into an image. Why do you think electron microscopes allow for greater magnification than compound microscopes?
Answer:
It is because the electron microscope uses a shorter wavelength electron
Explanation:
In an electron microscope the sample is always bombarded with a stream of electrons. These electrons usually have shorter wavelengths.
The electrons interact with the sample component well, the result of which is transformed into an image which is always clearer and allows for greater magnification than the compound microscope as a result of the short wavelength electrons being used.
Answer:
Due to the shortened wavelength electron it causes a greater magnification than compund microscopes.

The source of ATP and NADPH, which are required to synthesize glucose, is a
A) light independent reaction: glucose breakdown and carbon dioxide
B) light dependent reaction: electron transport and the splitting of water
C) light independent reaction: electron transport in the splitting of water
D) light dependent reaction: RuBP and the splitting of water
Answer:
B) light dependent reaction: electron transport and the splitting of water
Explanation:
The source of ATP and NADPH, which are required to synthesize glucose is a light-dependent reaction.
During the process of photosynthesis, light energy is required to tranport electrons that produces ATP and NADPH and splitting of water, generating O2.
Photosystem I (PSI) absorbs the light energy and electrons supplied from PSII (Photosystem II) are transferred to the protein ferredoxin, which further donates electrons to electron transport chain that produces ATP and to the electron carrier NADP+ to form NADPH.
Hence, the correct option is B.

Categorize Different Foods Categorize the food items below by selecting which macromolecule they are known to contain. apple steak celery olive oil potato avocado egg
Answer:
The correct categorization of the listed food items would be:
Carbohydrate: apple, celery, potato
Protein: Steak, egg,
Fat: Olive oil, avocado.
The four major macromolecules are carbohydrates, proteins, lipids, and nucleic acids.
Foods like apple, celery, and potato are rich in carbohydrates.
Foods like chicken, meat, eggs, et cetera are rich in proteins.
Similarly, foods like olive oil, mustard oil, butter, et cetera are rich in fats or lipids.
Explanation:
Answer: apple- carb; steak- protein; celery- carb; olive oil- lipid; potato- carb; avocado- lipid; egg- protein
Explanation:
Fruit and veggies are mainly made of carbohydrates because that is the storage and structural components they use (think glucose, cellulose, starch, etc.); Steak is a meat, and meat is technically muscle- muscle is built from protein; Olive oil and avocado are lipids because they are considered fats; Egg is protein because it is an animal by-product, and contains many amino acids, which build up proteins.

Time PeriodA- Sleeping
Time PeriodB-Walking
Time Period C- Running
Time Period D-Walking
Time Period E- Frightened by a loud Noise
Explanation:
The question is asking you to label the time periods shown with the activity that represents the heart rate of the person.
Your heart rate is lowest when you're sleeping because your body is not exercising or under any stress
When you're walking your heart rate will steadily go up but not as high as running because running requires more work and physical strain than walking
Your brain is under extreme stress when you are startled by a loud noise which causes a spike in heart rate.
Answer:
The answer is a
Explanation:
It is not b because when someone is frighented by a sudden loud noise the heart rate will be very pointy.
Not c either because sleeping makes your heart rate very low.
Not d because waking make your heart rate increase (about 90 beats per minute) but then stay in the same rate.
So probably a because running increases your heart rate at a very big level for a long time but then it drop when you stop.

If Earth was not spinning, there could still be a seasonal cycle. The correct option is B.
What is seasonal cycle?A hemisphere experiences winter and longer nights as it is tilted away from the Sun. A hemisphere experiences summer and longer days when it is inclined toward the Sun.
The duration and structure of daylight are largely constant at the equator.
The seasons are caused by Earth's tilted axis. Different regions of the Earth are exposed to the Sun's strongest rays at various times of the year.
Therefore, the Northern Hemisphere experiences summer when the North Pole tilts toward the Sun.
Seasonality describes regular cycles and changes in specific commercial sectors that depend on a specific season.
A season can refer to either a commercial season, like the Christmas season, or to a calendar season, such the summer or winter.
