How was life today similar and different to the Silurian period? ( animals, plants , organisms)
Answer:
The creatures developed in silurian period have evolved to live in sea bottoms.
Explanation:
Silurian life that is marine benthic which are bottom lying organisms belongs to the community of ecological zones that express themselves. As the gradients of temperature, pressure, and salinity. Consists of a community that is adapted to live in a darker region, used to lie in quieter environments that are in deep offshore water. These are much like the reef communities today as they do not tolerate excessive sediments. Prefer wave water that is shallow than 30 meters. These platforms are very gentle and are found over a hundred km gradients. Most of the fish represent the Silurian age and are widely distributed in marine environments. Examples of jawless fish, terrestrial fungi etc.Please help !!!!!!!!!!!

Is enzyme substrate complex concentration the product of enzyme concentration and substrate concentration?
Answer:
Yes
Explanation:
The enzyme substrate complex may be defined as the enzyme when interacting with the substrate at an active site and it produces a new product in the process. It is temporary molecule formed when the substrate comes in contact with the enzyme.
An enzyme is the molecule of a protein which acts like an organic catalyst and a substrate is a the molecule which interacts with the specific enzyme to form a product.
Therefore, the enzyme substrate complex concentration is the product of the substrate concentration as well as the enzyme concentration.

1. Which layer is the oldest? Which layer is the youngest? How do you know?
2. What are some characteristics of the organisms in layers 1-6?
3. What are some characteristics of the organisms in layers 7-12?
4. Develop a theory as to how the organisms in this area changed over time.
Answer:
the youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials.the oldest is 12(upper one) because decomposed material are found at the top most of organisms.they are highly decomposed material.they don't decompose easilyThe youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials. The oldest is 12(upper one) because decomposed material are found at the top most of organisms. They are highly decomposed material. They don't decompose easily.
What is Decomposition?Decomposition of organic matter is a complex process that involves the breakdown of complex molecules into simpler ones by the action of microorganisms. In the case of the layers mentioned, the higher layers are the oldest because the decomposed material is found at the top of the layer, and it takes a long time for the organic matter to decompose into soil.
The highly decomposed material in these layers is called humus. Humus is a dark brown or black organic substance that is a result of the decomposition of plant and animal matter. It is an essential component of healthy soil as it provides nutrients to plants and helps retain moisture in the soil.
Humus does not decompose easily because it is a stable form of organic matter. It is made up of complex molecules that are resistant to further decomposition. This makes it an important component of soil fertility as it can remain in the soil for hundreds of years, providing a steady source of nutrients for plants.
Overall, the highly decomposed material found in these layers is an important indicator of the age and health of the soil. Understanding the decomposition process and the factors that affect it can help us better manage our soil resources for agriculture, forestry, and other uses.

Which is evidence of climate-forced sea level rise?
A. decreased temperature of oceans
B. submerging of low islands and coastlines
C. temperature changes for surface currents
D. increased carbon dioxide in the atmosphere
In this exercise we have to use the knowledge of climate changes that demonstrate the increase in the sea level, in this way we have that:
The submerging of low islands and coastlines or letter B.
The rise in sea level caused by global warming could reach 2 meters in height by the end of the 21st century. This rise in the oceans would leave thousands of kilometers of coastline at the mercy of flooding, jeopardizing the safety of 745 million people worldwide.
What could happen with sea level rise?The recent rise in sea level is a result of global warming through two main processes: expansion of sea water due to warming of the oceans, triggering its thermal expansion, and the melting of ice masses.

What step in photosynthesis may occur during day and night? A.Light independant reactions B.Light dependant reactions c. Photolysis
Answer:
a is the answer
Explanation:
Light independent reactions of photosynthesis may occur during day and night.
STAGES OF PHOTOSYNTHESIS:
Photosynthesis is a metabolic reaction undergone by green plants to obtain their food using energy from sunlight. Photosynthesis is a process that involves two major stages: light independent reactions and light reactions. Light dependent reactions occur strictly under light conditions because light is needed to break down water molecules in a process called photolysis. In the light dependent reactions, water is broken down by light to give oxygen gas. In the light independent reactions, carbon dioxide is required.However, light independent reactions may occur during day and night. This is because light independent reactions does not require light to occur.

When an action potential is generated within a motor neuron, ________. When an action potential is generated within a motor neuron, ________. all of the muscle cells within the motor unit are stimulated to relax the muscle cells from a neighboring motor unit will contract every muscle cell of the motor unit is stimulated to contract only select muscle cells within the motor unit are stimulated to contract the muscle cells of the motor unit will occasionally contract
Answer:
every muscle cell of the motor unit is stimulated to contract.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.
Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.
For example, opening the door of a microwave oven as soon as its timer beeps.
Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.
Action potentials generates the nerve impulse in a motor neuron.
When an action potential is generated within a motor neuron, every muscle cell of the motor unit is stimulated to contract.
