Some reasons that the SI system uses metric units are the metric system's use of base 10, the lack of fractions, and the wide-spread use of the metric system around the world.

Answer:

Why do hotter substances have a tendency to rise?

Explanation:

 The molecules heats up and moves fast, since the air is less dense than the surrounding then the hot air floats upward.

In ecology, energy flow refers to the energy going from one organism to another in an ecosystem.

Trophic levels refer to the position that an organism has in a food web or food web.

The first level is the producers, which are autotrophic organisms that can produce energy from inorganic sources through processes such as photosynthesis. Here we can find plants, algae, and bacteria.

The next level is primary consumers, which are organisms that feed on the producers. This includes herbivores.

Next, there are secondary and tertiary consumers, which are carnivores that eat herbivores, and carnivores that eat carnivores.

There is also an extra trophic level of decomposers, which feed on the remains of other living beings and left behind nutrients that can be used by producers.

Just a fraction of the energy in each level passes to the next, which means there are fewer organisms going from one level to the next.

Answer:

c

Explanation:

The classification system for bacteria has undergone several revisions, and different sources may give slightly different answers. However, based on the most widely accepted classification system, there are 2 kingdoms in the domain Bacteria:Kingdom Eubacteria (true bacteria)Kingdom Archaebacteria (ancient bacteria or archaea)Therefore, the answer is option C, 2.

In the domain Bacteria, there are two recognized kingdoms: Eubacteria and Archaebacteria. Eubacteria includes the vast majority of known bacterial species, while Archaebacteria includes a smaller group of bacteria that are often found in extreme environments such as hot springs, salt flats, and deep-sea hydrothermal vents.So, the correct answer is C, 2.

Answer:

Crossing over, Independent assortment, and fertilization

Explanation:

Genetic recombination is the exchange of genetic material between organisms.

Genetic recombination is the process that occurs when two or more genomes combine to form a new genome. It is an important mechanism of evolution and is responsible for the diversity of life.

The three main processes of genetic recombination are natural selection, crossover, and independent assortment. Natural selection is the process by which certain traits are passed down from generation to generation because they are beneficial to the organism.

This process is controlled by the environment and can result in the evolution of new species. Crossing over is the process by which chromosomes exchange genetic material during meiosis. This process increases genetic diversity and can lead to the creation of new traits.

Finally, independent assortment is the process in which the alleles of a gene are randomly distributed to gametes during meiosis. This process also increases genetic diversity and can lead to the creation of new traits. All three processes of genetic recombination are necessary for the evolution of species and the development of new traits. Without these processes, genetic diversity would decrease and species would become less adaptable to their environment.

Answer:

attached is the correct answer

Answer:

decomposers

Explanation:

These are heterotrophic organisms that feed on dead animals and plants, secretions, or discarded parts of living beings, that is, organic matter.

And they break it down into inorganic.

Thus, inorganic substances that can be reused in the process of photosynthesis are returned, recycled, to nature.

Answer:

Cotyledon

Explanation:

it is the embryonic leaf so it supplies the nutrients to germinate.

The particles of the substance initially had high Kinetic Energy.​

Gas particles move quickly in all directions and regularly collide with one another and the container's side. The particles gather kinetic energy and accelerate as the temperature rises. The particles' real average speed is influenced by their mass and temperature.

In liquids, particles are quite close together and move with random motion throughout the container. Due to the closer proximity of the particles, collisions between them happen more frequently than in gases even if particles are moving quickly in all directions.

Answer:

The three important constants are: The person who will collect the data (Pinky), the environment in which the data will be collected (Pinky's backyard) and the element who will provide the data (the crickets).

Explanation:

Constants are very important elements in carrying out controlled experiments. This is because they allow all measurements and data collections to be carried out in constant systems that do not change and that will provide unity and control to the experiment.

In short, the constants are the elements of the experiment that will not be modified while the experiment takes place. These elements are: the person who is conducting the experiment and who will collect the data (Pinky), the environment in which the data will be collected (Pinky's yard) and the element who will provide the data (the crickets).

RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate. Thus, option B is correct.

RNA has a nucleic acid that has a single-stranded structure. RNA is also a genetic material. It helps in coding, decoding, and gene expression. RNA was the first genetic material and RNA can be replicated by itself. It has evolved all the methods that are necessary to store genetic information.

Thus, the hypothesis (B) RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate is the correct option.

Therefore, RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate. Thus, option B is correct.

The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).

1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).

Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).

Now we can express the ratio between 92 mL and 88.72 mL:

92 mL : 88.72 mL

Simplifying the ratio by dividing both sides by the greatest common divisor, we get:

46 : 44

So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

Depressants slow down the activity of the central nervous system, resulting in relaxation, drowsiness, and impaired judgment, coordination, and reaction time and effect the central nervous system.

The central nervous system (CNS) is the part of the nervous system that includes the brain and spinal cord. It is responsible for integrating sensory information from the body and the environment, and controlling behavior and motor responses. It consists of neurons, glial cells, and specialized receptors. The neurons process information and transmit signals to and from other parts of the body. The glial cells provide structural and metabolic support. The specialized receptors detect and transduce information from the environment, such as light and sound. The CNS is responsible for higher-order functions such as thought, emotion, learning, and memory. It is also responsible for controlling unconscious processes such as respiration, digestion, and other involuntary functions

Explanation:

1) regulating the production of specific proteins

In the given scenario, the regulation of blood glucose levels involves the hormones insulin and glucagon. This mechanism follows a negative feedback system.

When blood glucose levels are high, insulin is secreted, which allows cells to take up glucose from the blood, thus decreasing blood glucose levels. Conversely, when blood glucose levels are low, glucagon is secreted, stimulating the liver to break down glycogen into glucose and release it into the blood, increasing blood glucose levels.

When blood glucose levels deviate from the normal range, the body responds by secreting insulin or glucagon to bring the levels back to the normal range. The actions of insulin and glucagon are opposing and work to maintain the balance of blood glucose levels. As blood glucose levels increase, insulin is secreted to lower them, and as blood glucose levels decrease, glucagon is secreted to raise them. This feedback loop helps maintain homeostasis by keeping blood glucose levels within a certain range.

Therefore, the data demonstrate a negative feedback mechanism for the regulation of blood glucose levels.
