Explanation:

If a homozygous hairy plant (HH) is crossed with a heterozygous hairy plant (Hh), all of the offspring will be heterozygous hairy (Hh). This means that 100% of the tomato plant offspring will have hairy stems.

In genetics, the term "homozygous" refers to an individual that has two copies of the same allele for a particular trait. For example, if an individual has two copies of the allele for brown eyes (BB), they are homozygous for the trait of eye color.

On the other hand, the term "heterozygous" refers to an individual that has two different alleles for a particular trait. For example, if an individual has one allele for brown eyes (B) and one allele for blue eyes (b), they are heterozygous for the trait of eye color.

An individual's genotype, or the specific alleles they possess, can determine their phenotype, or the physical characteristics that they exhibit. For example, an individual with a genotype of BB (homozygous for brown eyes) would exhibit the phenotype of brown eyes, while an individual with a genotype of Bb (heterozygous for eye color) might exhibit either brown eyes or blue eyes, depending on the dominance of the alleles they possess.

Final answer:

When a homozygous hairy tomato plant is crossed with a heterozygous hairy plant, 100% of the offspring will have hairy stems, due to the dominance of the hairy allele.

Explanation:

The question asks: What percent of tomato plant offspring will have hairy stems if a homozygous hairy plant is crossed with a heterozygous hairy plant? Given that hairy stems (H) are dominant over hairless stems (h), the crossing can be denoted as HH (homozygous hairy) x Hh (heterozygous hairy).

This results in the following possible genotypes for their offspring: HH or Hh. Since both HH (homozygous dominant) and Hh (heterozygous) plants will have hairy stems due to the dominance of the H allele, 100% of the offspring will exhibit hairy stems.

Answer:

DNA has a double-helix structure because hydrogen bonds hold together the base pairs in the middle. Without hydrogen bonds, DNA would have to exist as a different structure. he major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.

Explanation:

The importance of the hydrogen bonds to the function of a DNA molecule as it holds the complementary strands and is responsible for its structure.

DNA has a double-helix structure. It has two antiparallel strands. Both strands have a sequence of nitrogenous bases that are linked together by hydrogen bonds.

The hydrogen bond holds together the base pairs in the middle. Adenine is always bound with thymine and guanine to cytosine in DNA by hydrogen bonds. In absence of hydrogen bonds, DNA would have to exist as a different structure, not a double helix.

In the food chain, consumers are organisms that feed on other organisms. Primary consumers, like rabbits, eat producers such as plants whereas tertiary consumers, such as eagles, eat secondary consumers. The letters assigned to these consumers would depend on their placement in an example food chain.

In a food chain, consumers are organisms that eat other organisms. The primary consumer is at the second level of the food chain, and they predominantly eat producers, such as plants and algae. For example, rabbits eating grass. Corresponding to the letters, if grass is represented by a letter A and rabbits by B, then letter B would represent the primary consumer. The tertiary consumer is usually at the fourth level of the food chain, they are typically carnivores that eat secondary consumers. For instance, if we have snakes that eat rabbits and eagles that eat snakes, the eagle would be the tertiary consumer. Hence, if eagles are represented by the letter D, then that letter D would represent the tertiary consumer.

Answer:

In primary succession newly exposed or newly formed rock is colonized by living things for the first time. and in secondary succession an area that was previously occupied by living things.

Explanation:

Due to incursions of r strategists, there is a rapid increase in diversity in early succession. If a few k strategists dominate the landscape in late succession, biodiversity may begin to decline. Mid succession has the greatest diversity. When secondary succession begins, species diversity decreases.

In biology, succession refers to the order in which plants and animals inhabit a biological community. As one group of plants and animals dies, another group of plants and animals emerges.

Early succession is becoming more diverse as a result of r strategist incursions. In late succession, if a few k strategists dominate the landscape, biodiversity may begin to decline.

Mid succession has the most variety. Species diversity decreases when secondary succession begins.

Early successional habitat was defined as areas with vegetation heights less than 3 meters, mid successional habitat as areas with vegetation heights between 3 and 16 meters, and late successional habitat as areas with vegetation heights greater than 16 meters.

Thus, this can be the primary difference between early succession, mid-succession, and late succession.

The windmill uses renewable energy, which comes from wind power, an indirect form of solar energy that can replenish itself and hence is sustainable.

The wind blows the windmill, and the windmill pumps water. The type of energy the windmill uses is renewable.

Wind energy is derived from the motion of air or water, which turns a turbine. This process is an indirect means of harnessing solar energy, as winds are produced by the uneven heating of air masses. Since the supply of wind is continuously renewed by the Earth's atmospheric processes, powered by the sun, wind power is considered a renewable resource.

In contrast, non-renewable energy sources such as nuclear energy, oil, coal, and natural gas cannot replenish themselves within a human timescale and will eventually be depleted.

Given the information available and understanding that renewable resources can be used indefinitely, the answer to the question would be D. renewable.

Renewable Energy: Sunlight, water, wind

Non-renewable Energy: Coal, oil, natural gas

Explanation: Nonrenewable sources of energy are rapidly being depleted and take a long time to replenish. Coal, oil, and natural gas are nonrenewable sources of energy. Renewable sources of energy replenish relatively quickly and are available in abundance. The wind, sunlight, and water are renewable sources of energy.

Natural resources can be renewable or nonrenewable based on their availability. Sunlight, water, and wind are renewable, while coal, oil, and natural gas are nonrenewable resources.

Renewable resources are the flow sources that are not limited in number and are replenishable when consumed or used. They get replaced through natural products and are in finite amounts.

Nonrenewable resources on the opposite are limited and do not get replenished easily, and take years to form. For example, coal, oil, and natural gas are limited and are not easily replaced.

On the other hand, sunlight, water, and wind are renewable resources that are available in abundant amounts in nature and get replaced through the natural cycles.

Therefore, sunlight, water, and wind are renewable resources.

Final answer:

Crossing two heterozygous individuals for brown and blue eyes yields a genotypic ratio of 1 BB:2 Bb:1 bb and a phenotypic ratio of 3 brown-eyed to 1 blue-eyed offspring.

Explanation:

When crossing two heterozygous individuals for eye color where B represents the dominant allele for brown eyes and b represents the recessive allele for blue eyes, the genotypic ratio is derived from the possible combinations of these alleles. A Punnett square for a heterozygous cross (Bb x Bb) will produce the following genotypes: BB, Bb, Bb, and bb. This results in a genotypic ratio of 1:2:1 (1 BB:2 Bb:1 bb). The phenotypic ratio, which looks at observable traits, will be 3:1 since the dominant brown eye allele will mask the blue eye allele in heterozygous individuals. Therefore, we will get 3 brown-eyed (BB or Bb) to 1 blue-eyed (bb) individuals.

A drastic reduction in the population of the photosynthetic protist zooxanthellae would likely lead to severe disruptions to the ecosystem, including coral bleaching, decreased biodiversity, and a reduction in the quantity of photosynthesis, which would directly affect food chains.

If a hypothetical catastrophic event drastically reduced the population of zooxanthellae, a photosynthetic protist, the most likely result would be a major disruption to its specific ecosystem. Zooxanthellae are symbiotic with coral polyps, providing them with essential nutrients derived from photosynthesis. In return, the coral provides the protist with a protected environment and the compounds necessary for photosynthesis. This symbiosis is particularly critical in nutrient-poor oceanic environments, with zooxanthellae enabling corals to secrete the calcium carbonate skeletons that form reefs.

Consequently, a major population reduction of zooxanthellae could lead to a phenomenon known as coral bleaching, where corals lose their algal pigments and eventually die. This loss would have significant implications for the entire reef ecosystem. Coral reefs, for example, provide shelter and food to a wide variety of marine organisms; therefore, their destruction would negatively impact biodiversity and the stability of oceanic ecosystems.

Moreover, since photosynthetic protists like zooxanthellae are important primary producers, their drastic reduction could significantly diminish the amount of photosynthesis in oceanic ecosystems. This effect on photosynthesis would mean less carbon fixation, which could impact food chains and the availability of organic molecules necessary for life, especially for those species that directly consume protists.
