Why are braided streams common in sedimentary rocks before the arrival of plants on land ?
Answer:
Braided rivers have a multithreaded plan form comprising many confluences and diffluences (Miall, 1977). Braid bars and channels can be classified as a hierarchy depending upon their relative size, and three orders of braiding can be seen in proglacial rivers with constant discharge. First-order braid bars are those largest bars which are separated by major channels. First-order bars are made up of a series of smaller, second-order braid bars, which are separated by smaller channels. Third-order braid bars are contained within second-order bars. Complexity of braid pattern is, however, strongly stage dependent, with rivers losing their braided character during peak flood conditions. Braid bars, mid-channel bars, unit bars, and islands have been described in braided river systems on a range of scales ranging from meters to kilometers. All bars are subject to dissection , remobilization, and migration by the appropriate discharge magnitude and frequency (Miall, 1977, 1983).

In eukaryotic cells, before RNA polymerase II-created records could be converted into protein items, these records (pre-mRNAs) should be appropriately handled to shape courier RNA (mRNA).
Three significant occasions comprise pre-mRNA handling: (a) 5′-end covering, (b) grafting, and (c) 3′-end polyadenylation.
In eukaryotic cells, pre-mRNAs go through three fundamental handling steps: Covering at the 5' end. Expansion of a poly(A) tail at the 3' end. Grafting to eliminate introns.
The three most significant stages of pre-mRNA handling are the expansion of balancing out and flagging variables at the 5′ and 3′ finishes of the particle, and the evacuation of interceding arrangements that don't determine the suitable amino acids. In uncommon cases, the mRNA record can be "altered" after it is deciphered

Explanation:
Compare the number and variety of organism placed in a kingdom taxing to the number and variety of organisms found in a species taxon
Answer:
Hence, there is a considerable increase in both number and characteristics from a species to a kingdom.
Explanation:
A species is defined as a group of individual organisms with fundamental similarities. They usually include closely related and morphologically similar organisms.
A group of related species makes a Genus, which in turn is included in a Family of similar genera.
The higher categories of taxonomy are based on a more wider scope of similarities. Families with some similarities make an Order. Related orders make a class.
A Phylum has different organisms with only one or two common features. For example, classes Mammalia, Pices and Amphibia all come under phylum Chordata due to presence of a notochord.
The final step is the Kingdom which is the classification of different Phyla.
Read the passage to answer the question.
Kangaroos are mammals, like humans. Like other mammals, they reproduce sexually with sperm fertilizing an egg that develops into an embryo. Unlike humans, however, once the embryo consumes its yolk sac to develop, it must be born. The infant is
about the size of a lima bean, mostly undeveloped except for its two front arms. It uses these to climb up its mother's abdomen and into her pouch. Once there, it feeds
on its mothers milk and continues to develop until it's big enough to finally leave. The muscle cells of a kangaroo organize together to form the structures that let a
kangaroo walk, run, and hop, allowing it to avoid predators.
Which term names a group of similar cells working together?
tissue
organ
organism
cell system
Tissue is a term that best describes a group of similar cells working together.
What is a tissue?
First, cells on their own can function individually, they are the basic unit/ building block of every living organism, and they have the ability to grow, multiply and die. The cells in a Kangaroo provide structure for the body.
But, when two or more cells come together to perform a similar function, then they become a tissue. Tissue comprises of similar cells that work together to perform a specific task.
From the passage, connective tissue is formed from muscle cells of a kangaroo that organize together to form the structures that let a kangaroo walk, run, and hop, allowing it to avoid predators.

Plants can reproduce both sexually and asexually. What are some examples of sexual reproduction in plants? Select ALL that apply. Responses
Sexual reproduction in plants involves the fusion of male and female gametes to produce offspring with genetic diversity.
Mechanisms that facilitate sexual reproduction in plants are examples:
1)Pollination and Fertilization: Many plants rely on pollinators, such as bees, butterflies, or birds, to transfer pollen from the male reproductive structures (anthers) to the female reproductive structures (stigma) of flowers.
This process enables the fusion of sperm cells within the pollen with egg cells in the ovules, leading to fertilization.
Examples include flowering plants like roses, sunflowers, and apple trees.
2)Seed Production: After fertilization, the ovule develops into a seed. Seeds contain an embryo, formed by the fertilized egg, enclosed within a protective seed coat.
The mature seeds can disperse and germinate to give rise to new plants.
Various plant groups, including angiosperms (flowering plants) and gymnosperms (conifers and cycads), reproduce sexually through seed production.
3)Alternation of Generations: In plants with a complex life cycle, such as ferns, mosses, and liverworts, sexual reproduction involves an alternation between two distinct generations: the gametophyte and the sporophyte.
The gametophyte generation produces gametes (sperm and eggs) through specialized structures, while the fusion of gametes gives rise to the sporophyte generation, which produces spores.
4)Self-fertilization: Some plants have the ability to self-fertilize, where the pollen from the anther of a flower is transferred to the stigma of the same flower or another flower on the same plant.
This allows for sexual reproduction without the need for external pollinators. Self-fertilization can be seen in plants like tomatoes, peas, and certain grass species.

Organic semiconductors are a new technology that scientists are considering for the next generation of solar
panels. Manufacturers want to produce efficient semiconductors at a low cost. Which type of organic
semiconductors would be most desired as a solar panel technology?
The specific properties of the most desired organic semiconductors for solar panel technology may evolve as advancements are made in the field.
In the context of solar panel technology, the most desired type of organic semiconductors would typically possess the following characteristics:
High Efficiency: The organic semiconductors should have a high power conversion efficiency, meaning they can efficiently convert sunlight into electricity. This is crucial for maximizing the electricity output of solar panels.
Tunable Bandgap: Organic semiconductors with a tunable bandgap would be advantageous. The bandgap determines the range of light wavelengths that can be absorbed by the material. A tunable bandgap allows for optimization to match the solar spectrum, enabling better absorption of sunlight and improved overall efficiency.
Long Operational Lifetime: The organic semiconductors should be stable and exhibit a long operational lifetime. Solar panels are expected to endure outdoor conditions for many years, so the materials used should be resistant to degradation, such as from exposure to UV radiation or moisture.
Scalability and Low Cost: Manufacturers aim to produce organic semiconductors on a large scale at a low cost. Therefore, desirable organic semiconductors should be readily synthesized using cost-effective methods and be compatible with high-volume manufacturing processes.
Environmental Friendliness: Organic semiconductors that are environmentally friendly and have low toxicity are desirable. This is aligned with the goal of sustainable and clean energy technologies.
It is important to note that the field of organic semiconductor research is still evolving, and scientists are continually working to improve the performance and characteristics of these materials.

Temperature regulation is the human condition chosen for this project. The human body must maintain a core body temperature of around 37°C, despite environmental temperature changes. The following information answers the questions:
What circumstances surround temperature regulation?Factors that can shift the body temperature include exposure to hot or cold environments, fever, and physical activity.
The organ systems involved in the homeostasis process of temperature regulation are the nervous and endocrine systems, as well as the integumentary (skin), cardiovascular, and respiratory systems.
Negative feedback is used to maintain temperature homeostasis. For example, when the body temperature rises, the hypothalamus signals the sweat glands to secrete sweat, which cools the skin and lowers the body temperature.
The stimulus is the change in body temperature, the receptor is the thermoreceptor in the skin or hypothalamus, the integrating center is the hypothalamus, the effector is the sweat glands or muscles, and the response is sweating or shivering.
Strategies to help maintain temperature balance include wearing appropriate clothing, using heating or cooling devices, and maintaining physical fitness through exercise.
