A DNA polynucleotide is composed of a chain ot DNA nucleotides. Which component of a nucleotide can be removed without breaking the chain

Answer:

Plant groups, also known as plant taxa, are classified based on shared characteristics. Some characteristics used to classify plants include the structure and arrangement of leaves, stems, and roots; the presence or absence of vascular tissue; the type of flowers or reproductive structures; and the number of cotyledons (seed leaves) present in the seed. Here are some examples of plant groups and some of their characteristics:

Ferns: Ferns are non-flowering plants that reproduce using spores. They have leafy fronds and root systems, but they do not have true stems, leaves, or flowers. Ferns are characterized by their vascular tissue, which helps transport water and nutrients throughout the plant.

Conifers: Conifers are a group of gymnosperms (non-flowering seed plants) that includes trees such as pines, spruces, and firs. Conifers are characterized by their needle-like leaves and their ability to produce seeds in cones. They also have vascular tissue to transport water and nutrients throughout the plant.

Angiosperms: Angiosperms are a group of flowering plants that produce seeds enclosed in fruit. They are the most diverse group of plants and include a wide variety of trees, shrubs, herbs, and other types of plants. Angiosperms are characterized by their flowers and the presence of cotyledons in their seeds.

Monocots: Monocots are a group of flowering plants that have one cotyledon in their seeds. They are characterized by their parallel-veined leaves, fibrous root systems, and the presence of vascular tissue. Monocots include plants such as lilies, grasses, and orchids.

Dicots: Dicots are a group of flowering plants that have two cotyledons in their seeds. They are characterized by their branching vascular tissue, net-veined leaves, and the presence of a taproot system. Dicots include plants such as roses, tomatoes, and oak trees.

The statement that best explains the state of the water cycle in this ecosystem is: Water stays predominantly in lakes or groundwater sources.

The correct option is C.

The entire group of organisms and the natural setting in which they live together make up an ecosystem. Through nutrient cycles and energy exchanges, these biotic and abiotic elements are interconnected. Photosynthesis is the mechanism by which energy enters the system and is absorbed into plant tissue.

Explanation:

There are several ways in which the expansion of housing developments in southern California might limit coyote population in the area:

Habitat loss: As housing developments are built, natural habitats are often destroyed, which can limit the available space for coyotes and other wildlife.

Human-wildlife conflict: As housing developments bring more people into close proximity with coyotes, there is an increased likelihood of conflict between humans and coyotes. This can lead to coyotes being killed or removed from the area.

Fragmentation of habitat: The expansion of housing developments can also lead to the fragmentation of coyote habitat, making it more difficult for coyotes to move and interact with other members of their species.

Changes in prey availability: Housing developments can also alter the availability of prey for coyotes, which can impact their population size.

Overall, the expansion of housing developments in southern California can have a negative impact on coyote populations by limiting their habitat, increasing the likelihood of conflict with humans, and disrupting their natural behaviors and ecological relationships.

These kittens come from the same litter because kittens from same litter can look different.

facts about Kittens -

Due to the possibility that kittens from the same litter may have different fathers, certain litters may contain half-brothers and half-sisters. This can occur when female cats have many matings with different males over a short period of time, resulting in multiple pregnancies and one litter.

Brothers are likely to have similar colors because male kittens always inherit their mom's fur color. The coats of female kittens, especially those with different dads, can differ from those of their sisters because they inherit a combination of their mother's and father's coloring.

Kittens will pick up a lot from their siblings throughout the first few months of life. You might notice kittens engaging in competitive play as they practice hunting and other activities with their littermates. Although it can occasionally appear a touch violent, as long as they are each pursuing and pouncing on the other in turn, it is a fantastic way for them to develop new abilities.

The main aim of Mendel's experiment was to understand the principles of inheritance of genetic traits in pea plants.

He performed a series of controlled crossbreeding experiments, where he carefully selected and crossbred pea plants that exhibited specific traits, such as seed color (yellow or green) and seed shape (round or wrinkled). He then recorded the characteristics of the resulting offspring and compared them to the characteristics of the parent plants. Through these experiments, Mendel discovered that certain traits were inherited in a predictable pattern, and that these patterns could be explained by the presence of  genes that controlled the inheritance of each trait. He also discovered that these factors could be dominant or recessive, and that the combination of these factors determined the phenotype (observable characteristics) of the organism. These discoveries formed the basis of Mendel's laws of inheritance, which are considered to be the foundation of the field of genetics.

To supply oxygen and remove carbon dioxide, the circulatory and respiratory system works together.

The respiratory system is what aids in breathing in oxygen and breathing out carbon dioxide. The circulatory system is the system that assists in supplying tissues with oxygen from the lungs and in removing carbon dioxide from the tissues by way of the lungs. In this way, both of these processes assist in the supply of oxygen and the removal of carbon dioxide as waste.

The blood that carries waste (CO₂) from the tissue via the heart will first carry the oxygen inhaled to the lungs, where it will be exchanged with the blood. The oxygen will then be sent to the heart, where it will be used to pump oxygen-rich blood to the tissues. Additionally, blood that has lost oxygen will transport waste from the tissue.

b. 50% chance of yellow skin

Explanation:

The likelihood that their kid will have yellow skin depends on the genetic makeup of both Patterson and Petunia. Patterson has the genotype Pp, which means he has one dominant allele for pink body color and one recessive allele for yellow body color. Petunia, on the other hand, has the genotype pp, which means she is homozygous recessive for yellow body color.

When they have children, each parent will contribute one of their alleles to their offspring. The offspring will have a 50% chance of inheriting the recessive allele for yellow body color from Patterson and a 50% chance of inheriting the recessive allele for yellow body color from Petunia. Therefore, the likelihood that their kid will have yellow skin is 50%.

When an isolated bacterial colony is discovered on an agar plate, there are a few assumptions that are typically made.

Firstly, it is assumed that the bacteria are a single species, which means that all of the bacteria in the colony are genetically related. This allows scientists to identify the bacteria by its unique characteristics, such as its color and size. Secondly, it is assumed that the bacteria are capable of reproducing, since it is only possible for the colony to form if the bacteria are able to divide and multiply. Lastly, it is assumed that the bacteria are not contaminated with any other microorganisms, since the bacteria need to be isolated in order to form a colony.

These assumptions allow scientists to accurately identify the bacteria and gain a better understanding of its characteristics.
