Fruit. Several plant species rely heavily on their fruits for seed distribution. Dehiscent fruits, like poppy capsules, usually include seeds that are spread directly from the fruits, which may still be attached to the plant.

The fruit only serves to spread its seeds. Fruit seeds need to be spread far from the parent plant so they can grow in a favourable environment with fewer competitions.

While some fruits can disseminate on their own thanks to internal systems, others need the assistance of wind, water, and animals. The structure, chemistry, and size of the seed are altered to aid in dissemination. Fruit that is distributed by wind is light and may have wings. like the dandelion, which has hairy, light structures that are good for dissemination.

The dark-colored rock pocket mice first appear in a population of light-colored rock pocket mice because they have a genetic mutation that affects their fur color.

Rock pocket mice are often light in color and inhabit light-colored rocks. Dark (melanic) mice, on the other hand, are located on dark lava, and their camouflaging colour protects them from bird and mammalian predators. We used markers in putative pigmentation genes to conduct association analyses and uncovered four mutations in the melanocortin-1-receptor gene, Mc1r, that appear to be responsible for adaptive melanism in one group of lava-dwelling pocket mice.

Surprisingly, another population of same mice on a separate lava flow shows no relationship with Mc1r mutations, indicating that adapted dark color developed indmelanic ependently in this species via modifications at other loci.

Darwin proposed the idea of natural selection, which held that organisms that survive better in a particular environment are selected over weaker ones and have a higher chance of passing down their genes to future children. In other words, nature favors them over lesser species.

Because of their deeper color and lack of camouflage, mice with black fur are more conspicuous and vulnerable to predator attacks, whereas mice with brown fur survive better. This would result in an increase in the number of brown-colored mice as they survive, whereas black mice would disappear.

the correct answer is a , they have a genetic mutation that affects their fur color.

Answer:

1. Three characteristics that all species belonging to the plant kingdom have in common are:

They are multicellular organisms
They are autotrophic, meaning they can produce their own food through photosynthesis

They have cell walls made of cellulose.

2. The numbers of stomata will differ in tropical plants and desert plants. Tropical plants tend to have more stomata on the underside of their leaves, while desert plants tend to have more stomata on the top of their leaves or in sunken pits. This helps protect the health of a plant because stomata are responsible for gas exchange, and having more stomata on the underside of the leaves helps reduce water loss through transpiration in humid environments. In contrast, having more stomata on the top of the leaves or in sunken pits can help reduce water loss in arid environments.If a plant's xylem and phloem become damaged, the plant will not be able to transport water, nutrients, and sugars throughout the plant. This can result in wilted leaves, stunted growth, and eventually death.

3. The xylem is responsible for transporting water and minerals from the roots to the rest of the plant, while the phloem is responsible for transporting sugars from the leaves to the rest of the plant.

4. We compare the dermal tissue of plants to human skin because they both serve as the protective outer layer of the organism. Dermal tissue in plants is the outermost layer of cells that covers the plant's surface and helps protect it from damage and water loss.

5. A plant may be able to survive if the ground tissue was damaged, depending on the extent of the damage. Ground tissue is responsible for photosynthesis, storage, and support in the plant. If only a small portion of the ground tissue is damaged, the plant may still be able to function, but if a significant amount of ground tissue is damaged, the plant may not be able to produce enough energy to survive.

Flowering Reproduction:

6. Flowering plants reproduce sexually. The male reproductive organs (stamens) produce pollen, which is transferred to the female reproductive organs (pistil) through the process of pollination. The pollen then fertilizes the ovules in the ovary, which eventually develop into seeds.

7. Flowers help other organisms in our environment by providing food and habitat for pollinators such as bees, butterflies, and birds. This helps promote biodiversity and maintain ecosystems.

8. The parts of a plant responsible for reproduction are the stamen (male reproductive organ), pistil (female reproductive organ), and the ovules (located in the ovary of the pistil). The stamen produces pollen, which contains the male gametes. The pistil contains the stigma (where the pollen lands), the style (a tube that leads to the ovary), and the ovary (where the ovules are located).

9. During the process of seed development, the fertilized ovule develops into a seed, which contains an embryo and a food supply (endosperm). The ovary develops into a fruit, which helps protect and disperse the seeds.

10. Most flowers are bright in color to attract pollinators such as bees, butterflies, and birds. The bright colors and sweet fragrances of flowers help to advertise the presence of nectar and pollen, which are the rewards for the pollinators' services.

False. Enzymes do not make the ΔG of a reaction more favorable. Instead, they lower the activation energy required for the reaction to occur.

which increases the rate of the reaction without changing the overall thermodynamics of the reaction or the ΔG. In other words, enzymes do not change the free energy change of a reaction, but they do increase the rate at which it occurs.Enzymes are biological catalysts that speed up chemical reactions in living organisms. They work by reducing the activation energy required for a reaction to occur, which is the minimum energy required to initiate a chemical reaction. By lowering the activation energy, enzymes make it easier for reactant molecules to achieve the necessary energy to undergo a reaction.However, enzymes do not change the overall thermodynamics of a reaction, including the change in free energy (ΔG) that occurs during the reaction. ΔG represents the difference in free energy between the reactants and products of a reaction, and it determines whether a reaction is energetically favorable (exergonic, ΔG < 0) or unfavorable (endergonic, ΔG > 0).Enzymes do not affect the overall free energy change (ΔG) of a reaction. Instead, they lower the activation energy, which enables the reaction to proceed more quickly and efficiently. This is accomplished by binding to the reactant molecules in a way that stabilizes the transition state of the reaction, thereby reducing the energy required to reach that state.In summary, enzymes do not make the ΔG of a reaction more favorable. Instead, they lower the activation energy required for the reaction to occur, which increases the rate of the reaction without changing the overall thermodynamics of the reaction or the ΔG.
