Explain two advantages that vascular plants have over nonvascular plants such as mosses and liverworts.

Fossil records provide evidence of natural selection because one can see what species and what type of species (specifically what type of special trait the species had) reproduced and lived for longer.

For example, we have 5 different fossils of the same animal;

1. Lived about 45 years; had long legs that made it run faster - 5 offspring

2. Lived about 8 years; had short and stubby legs, was very slow - 0 offspring

3. Lived about 67 years; had long legs that made it run faster and a good nose - 8 offspring

4. Lived about 40 years; had a good nose and normal legs - 6 offspring

From all of that information you can see that the prefered trait was having longer legs and a good nose survived and reproduced multiple time, you can also see that the organism that had short legs did not survive for long and did not reproduce.

ANSWER;YES

Sí, el sonido viaja más rápido en un medio donde las partículas están estacionadas juntas que donde están dispersas. Por lo tanto, las moléculas de agua son 800 veces más que las moléculas de aire. Por lo tanto, el sonido viaja más rápido en el agua que en el aire. De hecho, las intensidades de sonido pueden viajar kilómetros por delante en el agua porque las moléculas / partículas transportan las ondas de sonido.

Sin embargo, debido a que las partículas en el aire no se juntan, durante el recorrido, a medida que las ondas de sonido viajan, el sonido se reduce en rango, porque el padre que va más las ondas de sonido pierde energía, porque no hay partículas para transportar el sonido. más como en el agua.

En general, los viajes de las ondas sonoras del aire al agua se llaman fenómenos de refracción. Es la curvatura de las ondas sonoras a medida que ingresa al agua desde el aire.se debe a diferencias en la velocidad del sonido entre los dos medios

Yes,Sound travels faster in a medium where the particles are parked together than where they are scattered. Thus water molecules are 800 times more than air molecules.Hence, sound travels faster in water than in air. In fact the sound intensities  can travels kilometers ahead in water because the molecules/particles  carry the sound waves.

However, because the particles in the air are not packed together, during the tour, as the sound waves travels, the sound get reduced in range, because the father  you go the more the sound waves loses energy, because no particles to carry the sound further like in the water.

Generally  the travels of sound waves from air to water is called refraction phenomenon.It is the bending of sound waves as it enters the water from the air.,

The figure is showing the various sources of energy consumption from 1990 to 2018. It is divided into three main categories: electricity, transport, and other energy sources.

Energy source is a material or device that is used to supply energy to an end-use. Examples of energy sources include fossil fuels such as coal, oil, and natural gas; nuclear fuel such as uranium; renewable sources such as solar, wind, and geothermal; and stored energy sources such as batteries, fuel cells, and flywheels.

The electricity category is further divided into renewable sources such as wind and solar, nuclear, and other sources such as coal and natural gas. The transport category is split into petroleum, biofuels and other sources. Lastly, the other energy sources category is divided into solid biomass, liquid biofuels, and other sources such as geothermal energy. The data for each energy source is displayed for each year along with the total energy consumption for that year. The figure also includes labels for each energy source and a legend at the bottom left that displays the fuel type for each energy source. Finally, the source and notes can be found at the very bottom of the figure.

The process of ecological succession occurs when a region's species and habitat mix shifts through time until a A key idea in ecology is ecological succession.

Environmental change that is organic, slow, and orderly is called ecological succession. One plant community is gradually replaced by another through ecological processes over time.

The successive emergence and extinction of species within a community throughout time is referred to as succession. In primary succession, living creatures inhabit newly exposed or produced land; in secondary succession, an environment is disturbed and the remains of the preceding community are left behind.

Some species boast armature such as thorns, or spines that ward off slavering herbivores. Some are loaded with poisons to sicken or kill them. And while tomatoes may not be able to scream, as L.

If only nuclear division occurs without cytokinesis during the process of cell division, the result would be the formation of multinucleated cells or cells with multiple nuclei.

Cell division consists of two main processes: nuclear division (mitosis) and cytoplasmic division (cytokinesis). During nuclear division, the nucleus of the cell divides, ensuring that each daughter cell receives a complete set of chromosomes.

On the other hand, cytokinesis involves the division of the cytoplasm, resulting in the separation of the two daughter cells.

If only nuclear division occurs without cytokinesis, the cell would undergo mitosis but not divide into two distinct cells. As a result, the daughter cells would share a common cytoplasm, leading to the formation of multinucleated cells or cells with multiple nuclei. These multinucleated cells are known as syncytia.

Syncytia can be found in various biological processes and tissues. For example, muscle fibers are multinucleated cells formed by the fusion of multiple precursor cells during development. Similarly, certain fungal hyphae and giant algae cells can have multiple nuclei due to incomplete cytokinesis.

In summary, if only nuclear division occurs without cytokinesis, the cell would produce multinucleated cells or cells with multiple nuclei, where the daughter cells remain connected by a shared cytoplasm.

Answer:

Answer 4: (x + 7)

Explanation:

We can say that \(x^2 + 9x + 14\) is \(x^2 + 7x + 2x + 14\), and if you factor x out of \(x^2 + 7x\) and you factor 2 out of \(2x + 14\), you get that \(x(x + 7) + 2(x + 7)\), and then since you're multiplying x + 7 by x and 2, you can say that this is equal to \((x+2)(x+7)\), and one of the factors is x+7, which is answer 4.

If the pattern of inheritance for a trait is complete dominance, then an organism heterozygous for the trait would normally express A the dominant trait only.

In terms of genetics, the term "dominant" describes the interaction between two inherited copies of a gene that contributes to a certain trait and an observed trait.

Each gene has two alleles that an individual inherits from each parent. For a dominant trait, just one copy of the dominant allele is necessary for the characteristic to manifest. The dominant allele obscures the effects of the other allele (the recessive allele).

A person who contains two copies of a dominant allele typically displays the same trait as someone who carries just one copy. In contrast, a recessive trait must be expressed by both alleles in order to exist.

Therefore, If the pattern of inheritance for a trait is complete dominance, then an organism heterozygous for the trait would normally express A the dominant trait only.

abiotic

Explanation:

abiotic - nonliving components of an ecosystem that can affect the living organisms.

Temperature is a nonliving component and it affects the organisms that live within a certain environment.

Therefore the answer is Abiotic

Reasons its not the other answers:

Biotic factors must be living things

Temperature is not a living thing therefore Biotic cannot be the answer

Same with living, temperature is not living therefore the answer cannot be living.

Temperature plays a huge role in an ecosystem therefore it is considered an important component and the answer cannot be unimportant.

2.1.2. The numbers and names of the places (regions) where Chlorophyll-containing cells occur are:

2.1.3. The mesophyll is the primary site of photosynthesis in plants. The mesophyll is a layer of cells that lies between the epidermis and the phloem. The mesophyll cells contain chlorophyll, which is the green pigment that captures sunlight and uses it to convert carbon dioxide and water into oxygen and glucose.

2.1.4. The mesophyll cells are structurally adapted for photosynthesis in several ways. First, the mesophyll cells are packed with chloroplasts, which contain chlorophyll. Second, the mesophyll cells have a large surface area, which allows them to absorb more sunlight. Third, the mesophyll cells have a thin layer of cytoplasm, which allows for the rapid diffusion of gases and nutrients.

2.1.5. Phloem

The phloem is a vascular tissue that transports food and nutrients throughout the plant. The phloem is made up of two types of cells: sieve tubes and companion cells. Sieve tubes are long, thin cells that are connected by small pores. Companion cells are smaller cells that are attached to sieve tubes. Companion cells help to provide energy and support for sieve tubes.
