11. A flower produces a seed. Explain why this is an example of sexual reproduction
Answer:
itrequires genetic material (DNA) from two parents. The parent plants have male and female sex cells, called gametes. ... Seeds produced through fertilization contain genetic material from both parents.
The production of a seed by a flower is an example of sexual reproduction because it involves the fusion of male and female gametes (pollen and ovules) to form a genetically diverse offspring.
Sexual reproduction is a type of reproductive process that involves the combination of genetic material from two parent organisms, resulting in the formation of genetically diverse offspring. In the case of a flower producing a seed, sexual reproduction occurs through a series of specialized reproductive structures and processes.
Male Gamete Production (Pollen): Flowers produce male gametes, or pollen, in structures called anthers. Pollen contains the male reproductive cells necessary for fertilization. When pollen is mature, it is released from the anthers.
Female Gamete Production (Ovules): Flowers also produce female gametes, or ovules, within the ovary. Each ovule contains an egg cell, which is the female reproductive cell. The ovary is located at the base of the flower.
Pollination: Pollination is the process by which pollen from the male reproductive structures (anthers) is transferred to the female reproductive structures (stigma) of the same or a different flower. This can occur through wind, water, insects, birds, or other means.
Fertilization: Once pollen lands on the stigma of a compatible flower, it forms a pollen tube that grows down into the ovary. This tube delivers the male gametes to the ovules, where fertilization occurs. Fertilization is the fusion of a male gamete with a female gamete to form a zygote, which develops into an embryo within the seed.
Seed Formation: After fertilization, the ovule develops into a seed, which contains the embryo, endosperm, and protective seed coat. The embryo carries genetic information from both parent plants, resulting in genetic diversity.
The combination of genetic material from male and female parent plants results in offspring with unique genetic characteristics. This genetic diversity is advantageous for the survival and adaptation of species to changing environments. Therefore, the production of a seed by a flower is a prime example of sexual reproduction, involving the fusion of gametes to create genetically diverse offspring with traits inherited from both parents.

what differentiates amino acids from one another
Answer:
Every amino acid comprises a hydrogen atom, a carboxyl group, an alpha-amino group and also the R-group (which makes the side chain). The side chain present in every amino acid is different. Therefore, the only primary factor that makes each amino acid different is the presence of R-group.

Animals release energy needed for growth and repair through a
Answer:
The best answer of how animals release energy needed for growth and repair is ( C ) : A series of chemical reaction during cellular respiration
Animals need energy to function effectively daily and also to repair. one way by which Animals get such energy is through cellular respiration.
during cellular respiration the series of chemical reaction that leads to the release of energy follows this pattern.
Consumed food ( sugar/glucose molecules ) are broken down
The energy released from the breakdown is then transformed into ATP energy
The transformed ATP energy is then used for Cellular activities ( growth and repair of animal cells )
Photosynthesis and Cellular respiration are have similar process but the former ( photosynthesis ) occurs in plants not Animals.
Hence we can conclude that animals release energy needed for growth and repair through a series of chemical reaction during cellular respiration.

Which would conserve more energy if all humans ate only vegetables or ate only meat
Answer:
There would be more conservation of energy if human beings it only meat.
Explanation:
this is because meat consists of a significant portion of the fat. The amount of of energy that is liberated per molecule of fat is almost twice the amount of energy that is liberated by carbohydrate or protein. As a result of this the total energy consumption will be more if human being consumes only fat. however it takes more time to digest fat as compared to that of carbohydrate and protein.

Which of the following sequences best illustrates primary succession in a forest?
A. forest fire – pioneer species – willow - hardwood
B. bulldozed trees – shrubby weeds – cottonwoods – pine trees
C. exposed rock – lichens – weeds – shrubs – hardwoods – stable forest
D. flood – mosses – ground cover - shrubs
Answer:
C.
Explanation:
Primary succession is where it is a new area, not one where the area was simply made uninhabitable which gets rid of A, and B. C goes into more detail as to what actually happens as lichens consume the rocks while weeds come in afterwards due to the soil being formed since the lichen has broken down the rocks. Shrubs follow because enough soil has formed. followed by hardwoods and trees cause the roots of previous plants have formed enough soil for larger organisms and eventually a forest

a) warmer
b) cooler
c) more dense
d) less dense
**Answer and I will give you brainiliest**
Answer:
I'm pretty sure the answer is D.) Less Dense
Explanation:
Answer:
d) less dense
Explanation:
When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.

Explanation:
A de-shelled egg is placed in tap water. The egg grows in size.
What is the best explanation for this change in size?
Ions in the water moved into the cell through diffusion because there were more ions outside the cell than inside the cell.
Water moved into the cell by osmosis because the solute concentration was higher inside the cell than outside the cell.
Water moved out of the cell by osmosis because the solute concentration was higher outside the cell than inside the cell.
Water moved into the cell by diffusion because there is more water inside the cell than outside the cell.
The best explanation for the change in the egg's size is that Water moved into the cell by osmosis because the solute concentration was higher inside the cell than outside the cell. Option B.
--------------------------------------------
When talking about solutions, we can classify them as follows,
Hypertonic ⇒ A hypertonic solution has a higher concentration of solute than the cell. This means that in the cell interior, the solute concentration is lower than in the solution itself. Isotonic ⇒ The solute concentration is the same inside the cell and outside. Hypotonic ⇒ A hypotonic solution has a lower concentration of solute than the cell. This means that in the cell interior, the solute concentration is higher than in the solution itself.
Water is considered to be a hypotonic solution.
When a cell is in a hypotonic solution, through osmosis, water moves toward the cell.
Note: In this example, the egg is the cell.
Osmosis is the phenomenon that occurs when two dilutions of different concentrations -in this example, the interior of the cell and the solution- are separated by a semipermeable membrane.
The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.
Water tends to go from the hypotonic solution to the cell interior and keeps doing so until concentrations are equal in the cell interior and exterior.
As water enters the cell, the cell begins to enlarge and becomes bigger-sized. And because cells can not limit the amount of water moving in, it keeps swelling until the membrane can not stretch anymore, and lysis occurs. It bursts.
What we need to consider is
When a cell with a semipermeable membrane is placed in a hypotonic solution, water enters the cell. When a cell with a semipermeable membrane is placed in an isotonic solution, there is no water movement. When a cell with a semipermeable membrane is placed in a hypertonic solution, water gets out of the cell.So, the best explanation for the change in the egg's size is Water moved into the cell by osmosis because the solute concentration was higher inside the cell than outside the cell. Option B.

Answer:
Catabolic pathways release the energy stored in complex molecules through the breakdown of these molecules into simpler compounds. Anabolic pathways, sometimes called biosynthetic pathways, require energy to combine simpler molecules into more complicated ones.
Exergonic reaction proceeds with a net release of free energy and is spontaneous. Endergonic reactions are nonspontaneous; they must absorb free energy from the surroundings.
Enzymes are biological catalysts agents that speed the rate of a reaction but are unchanged by the reaction
Investment of activation energy is known as a free energy of activation where the energy that must be absorbed by reactants to reach the unstable transition state, in which bonds are likely to break, and form which the reaction can proceed.
