Force of contraction decreases, when the skeletal muscle is fully contracting for a long duration because it creates a lag in muscle cycle duration.
What is skeletal muscle contraction?The neuromuscular junction, which is the synapse between a motoneuron and muscle fiber, is just where skeletal muscle contraction begins.
The propagation of nerve impulses to the motoneuron and subsequent depolarization leads the presynaptic membrane's voltage-gated calcium channels to open.
Calcium ions bind to the protein complex troponin, exposing the active-binding sites on actin, and triggering the muscular contraction cycle. Whenever the actin-binding sites are revealed, the high-energy myosin head crosses that gap, resulting in the creation of a cross-bridge.
Therefore force of contraction will decrease in skeletal muscle when contracting for a long duration.

design solution to treat sewage water in anaerobic digestion
An anaerobic treatment cycle entails wastewater entering a bioreactor plug socket containing sludge, a thick semi-solid substance rich in anaerobic bacteria and other microorganisms that break down the organic contaminants in the wastewater.
What is anaerobic digestion?Anaerobic digestion is a process in which bacteria break down organic matter in the absence of oxygen, such as animal manure, wastewater biosolids, and food waste.
Anaerobic digestion is the most commonly used sludge treatment method. In this process, a significant portion of the organic matter (cells) is broken down into carbon dioxide (CO2) and methane (CH4) in the absence of oxygen.
Thus, this is the way to treat wastewater anaerobically.

A bacterium does not continuously swim at one speed in one direction. Different arrangements and structures of flagella contribute to changes in speed and direction when necessary. How does motility relate to flagellation?.
Different arrangements and structures of flagella contribute to changes in speed and direction when necessary. Motility relates to flagellation as:
Polar flagella (in any one or both the poles of the bacterium) makes the organism move very quickly in a particular direction.Peritrichous flagella (present all over the cell) helps the organism in rotation and tumbling.Amphitrichous flagella ( present in bulk at both the ends) move the organism slowly as these flagella work alternately and hence stop periodically to change directions).Flagella is a hair like structure present in both prokaryotic as well as eukaryotic cell. It helps in motility. An organism can have a single flagella or multiple and these can be arranged in various ways.

When scientists use logic to determine the age of one fossil compared to another, they use this
type of dating?
Relative
O Carbon
O Absolute
Answer: Carbon Dating though measuring Carbon-14 levels
Explanation:
Scientist measure the age of a fossil determined on the Carbon-14 level compared to the Carbon-12 level. This method works because:
All organisms after their death stop replenishing the amount of carbon in their body. That means that they will have an equal amount of carbon-12 and carbon-14 until they die. Unlike carbon-12, carbon-14 is unstable and overtime will go through beta decay. Overtime, a carbon-14 neutron will become a proton and release an electron, transforming into nitrogen-14.This leads to a drop in carbon-14 level, and because of this, geologist compare the level of carbon-14 to carbon-12 to determine how long it has taken to reach such stage.what is the function of structure e? the cell membrane. each letter marks a definite structure of the membrane. letter a marks the structure represented by a branched sequence on the integral protein. b marks a branched structure on the cell membrane. c marks a large elongated structure outside the cell. d marks part of the membrane, which consists of two rows of molecules. each molecule has a head and a tail. e marks a molecule, which is one of the membrane components. such molecules are randomly integrated in the membrane. f marks a structure that penetrates two layers of the membrane. what is the function of structure e? the cell membrane. each letter marks a definite structure of the membrane. letter a marks the structure represented by a branched sequence on the integral protein. b marks a branched structure on the cell membrane. c marks a large elongated structure outside the cell. d marks part of the membrane, which consists of two rows of molecules. each molecule has a head and a tail. e marks a molecule, which is one of the membrane components. such molecules are randomly integrated in the membrane. f marks a structure that penetrates two layers of the membrane. detection of environmental change cell-cell communication stabilization of the phospholipids structural support of the cell transport across the plasma membrane

The density remains the same because changing the amount of the substance will reduce the mass & volume by the same value.
What is density?
Mass per unit volume is the definition of a material's density. Density, or mass per unit volume, is defined as the ratio of mass to volume. It gauges how so much "stuff" an object looks in relation to its volume (cubic meter or cubic centimeter).
In essence, density is an indicator of how closely together stuff is packed. The Greek scientist Archimedes is credited with discovering the concept of density, which is simple to calculate if you understand the formula and are familiar with the relevant units.

O Particles have enough kinetic energy to begin to move.
O Particle motion slows to a vibration, preventing particles from escaping forces of attraction.
Answer:
A
Explanation:
Took the test
At 0° Kelvin or absolute zero, all particle motion stops. Thus, option A is correct.
What is absolute zero?
The lowest limit of the thermodynamic scale that measures temperature is known as absolute zero. It is also a condition in which entropy and enthalpy of a ideal gas which is cooled reached to its maximum value and the reading is taken as zero kelvin.
Absolute zero is also the lowest energy temperature in the thermodynamics and there is no cooling of an object on temperature that is exactly absolute zero.
Thermal energy is also hold a conservation of energy it means energy can't be created nor be destroyed but in real world when energy is transformed from one system to another system the efficiency is always decreases. So we can say that loss of energy is takes place but it's loss to friction or resistance in term of mechanics.
