The sugar in RNA is, the sugar in DNA is
deoxyribose; ribose
glucose; deoxyribose
ribose; glucose
ribose; deoxyribose
Answer:
Last choice: ribose; deoxyribose
Explanation:
Ribose (otherwise known as D-ribose) is a sugar found in RNA (ribonucleic acid). It alternates with phosphate groups to create the “backbone” of the RNA polymer.
Deoxyribose (sugar in DNA) is one of the three components of nucleotides for DNA. Each nucleotide consists of a phosphate group and a nitrogenous base: adenine, thymine, cytosine, guanine, and deoxyribose.
Glucose is a type of sugar which is a common and crucial energy source in living organisms and is often a component in various carbohydrates. Plants can create glucose by going through a process called photosynthesis, and once it's done with the process, they use the glucose (sugar) as their food for energy.
Name the process by which the present diversity of plants and animals arose from the earliest and primitive organisms
The process is called evolution, specifically biological or organic evolution.
What is evolution?The process of change in the inherited features of populations of organisms over many generations is called evolution. Genetic diversity, natural selection, mutation, gene flow, and genetic drift are some of the forces that propel it. Biology's foundational idea of evolution is what gives life on Earth its diversity. It examines the relationships between species and the ways in which they have evolved to the various habitats in which they dwell. Charles Darwin and Alfred Russel Wallace initially put forth the theory of evolution in the 19th century, and it has since been backed by an abundance of empirical data from disciplines like genetics, palaeontology, and biogeography.

dna polymerase iii ""reads"" a template strand and synthesizes a complementary strand of dna in the ________ to __________ direction
DNA polymerase III reads a template strand and synthesizes a complementary strand of DNA in the 5' to 3' direction.
DNA polymerase III is an enzyme involved in DNA replication, responsible for synthesizing a new DNA strand during the replication process. It reads a template strand, which serves as a guide, and generates a complementary strand by adding nucleotides in a specific direction. The directionality of DNA synthesis is crucial for accurate replication.
The direction in which DNA polymerase III synthesizes the new strand is referred to as the 5' to 3' direction. This means that the enzyme adds nucleotides to the growing DNA chain starting from the 5' end (where the phosphate group is attached to the 5' carbon of the sugar) and moving towards the 3' end (where the hydroxyl group is attached to the 3' carbon of the sugar). The template strand acts as a template for complementary base pairing, guiding the synthesis of the new strand.
This 5' to 3' directionality is a fundamental aspect of DNA replication. It ensures that the new DNA strand is synthesized in the correct sequence, complementary to the template strand. Additionally, DNA polymerase III can only add nucleotides to the 3' end of an existing DNA or RNA strand, requiring a primer to initiate replication. This primer provides the necessary 3' hydroxyl group for nucleotide addition.

which fsso mode requires more fortigate system resources (cpu and ram)?
The FSSO mode that requires more FortiGate system resources (CPU and RAM) is the Polling Mode.
FSSO (Fortinet Single Sign-On) is a mechanism for authenticating users and computers from a Windows Active Directory network. It permits users to sign in once and automatically obtain access to authorized network resources while keeping them secure. Users do not need to re-enter their credentials each time they switch between services. This process involves an agent program running on a Windows server that communicates with the FortiGate system. The communication between the agent and the FortiGate system can be done in either of the two methods, which are as follows: Polling mode: In this mode, the FortiGate unit polls the FSSO collector agent for group membership information. This process involves querying the domain controller every five seconds for any updates. Sticky mode: In this mode, the FSSO collector agent does not send updates to the FortiGate unit. The FortiGate unit maintains a local table that it uses to map IP addresses to users or machines in this case. The Polling mode requires more FortiGate system resources (CPU and RAM) because it queries the domain controller every five seconds for any updates. Therefore, the FortiGate unit is required to process a higher volume of data than the Sticky mode.

true/false: below the lithosphere, terrestrial planet mantles are primarily melted rock (magma).
True, below the lithosphere, terrestrial planet mantle is the layer of interior that lies beneath the crust and outer core.
Above the lithosphere, terrestrial planet mantles are primarily melted rock (magma) is because there aren't many SiO2 molecules that could be converted into glass by heat and pressure at great depths in the mantle—only CaO molecules can do so under these conditions (and they don't do it very well)..
The mantle has a thick upper mantle and a thin lower mantle. The upper mantle is where most of the crust forms, because it contains relatively large amounts of silica from which the crust can grow. The lower mantle has a much higher proportion of iron and magnesium than the upper mantle does, and it also contains small quantities of silicon-30 (SiO2) and calcium-40 (CaO).

In general, a stable equilibrium results when the rate of population growth for each species is equal to zero, which means that the populations are not increasing or decreasing over time. the correct answer is c.
According to the model, a stable equilibrium results when intraspecific competition is stronger than interspecific competition. This means that individuals within a species are more likely to compete with each other for resources than with individuals from the other species. When this is the case, the species are able to coexist without one species completely outcompeting the other.

______ have distinct seasonal changes, allowing for defined growing seasons. a. borreal forests
b. temperate forests
c. tropical rainforests
Boreal forests have distinct seasonal changes, allowing for defined growing seasons.
These forests are found in the northern hemisphere, typically in Canada, Scandinavia, and Russia. During the summer months, the temperatures are mild and the days are long, providing ample sunlight for photosynthesis and plant growth. However, during the winter months, temperatures drop significantly, and the days are short, resulting in a lack of sunlight and a period of dormancy for many plants.
In contrast, tropical rainforests do not have distinct seasonal changes. They are found near the equator and experience a consistent climate throughout the year, with high temperatures and high levels of precipitation. This climate allows for year-round plant growth, with new plants sprouting up as old ones die off. The lack of distinct seasons in tropical rainforests can make it difficult for farmers to determine the best time to plant crops, and can lead to a constant battle against pests and diseases.
Overall, the distinct seasonal changes in boreal forests allow for a more defined growing season, which can be beneficial for farming and forestry. However, the year-round growth in tropical rainforests can also provide benefits, such as a constant supply of resources for indigenous peoples and a diverse range of plant and animal life.
