Explanation:
Increase in tension by increasing the number of motor units that are stimulated is called _________. Increase in tension by increasing the number of motor units that are stimulated is called _________. muscle tone autorhythmicity hypertonia recruitment
Answer: Recruitment
Explanation:
A motor unit is made up of a motor neurone and all the muscle fibre it supplies nerve to.
Within a muscle, the muscle fibers are functionally organized as MOTOR UNITS within a muscle.
MOTOR RECRUITMENT causes an increase in muscle tension which occurs when there is an increased number of stimulated motor units.
During a muscle contraction, the weakest motor units are recruited to contract first,The more weight (resistance) you add to a muscle, the more motor units you will need to recruit in order to generate movement.Recruitment stops as soon as movement starts, result is a smooth, even muscle contraction. I hope this helps, thanks.

The Eocene period exists in Earth’s history around 34 MYA. What could a scientist do to determine what era the Eocene period belongs to on the geologic time scale?
Answer:
To understand what era the Eocene period belongs to on the geologic time scale, the scientist would have to examine the Cenozoic era to understand all information related to it.
Explanation:
First, let's start with an explanation of terms.
MYA simply means Millions of Years Ago Time Scale is a sequence or organisation of events which is used as a yardstick to measure the duration of history or how long the earth has existed. Eocene Period refers to the geological epoch that lasted from about fifty-six to approximately forty MYA. It is also defined as the second epoch of the Paleogene Period within the modern Cenozoic Era.
Given the definition of the Eocene Period, to understand what era an Eocene period belongs to, the person must carefully study the Cenozoic era.

Intracellular transport, changes in cell shape, cell motility and animal locomotion depend on the microtubules, microfilaments, motor proteins and their accessory proteins. You should be able to explain how each of these four movement functionsabove are achieved by microtubules and microfilaments. Make sure you understand the role of the different motor proteins involved that are specific to microtubule movement vs. microfilament movement. Microtubules and microfilaments also have important roles in the cytoskeleton.
Answer:
Intracellular transport is taking place with the help of microfilaments and microtubules. The plays the role of a highway for motor proteins such as dynein, kinesin, and myosin, which acts as the car of this highway that helps in transport.
Motor proteins help in changing the ATP to ADP by binding to it and attach or detach to the other parts of the cytoskeleton for transporting the vesicles as these proteins move.
Kinesin and dynein both are microtubule motor proteins. Kinesin transports full vesicles away from the nucleus, Dynein transports empty vesicles back towards the nucleus and myosin is a microfilament motor protein that transports both vesicles along microfilament.

What is the potential problem for robotic rovers on Mars?
Answer:
The limited autonomy of the robotic rovers on Mars posed a big problem.
Explanation:
Missions are very costly, and can lead the project to fail with the simplest errors. If the rover was permanently trapped on a rock or destroyed, it would have a catastrophic impact on the exploration. Thus on-board technologies would still be more traditional than what a laboratory environment has sought. The autonomous rovers will considerably increase the productivity of crew. Responsibility for their own well-being is also useful for the rovers: to prevent getting hurt, to recognize and correct recoverable hardware and software faults.
How are viruswa different from bacteria ?
Answer: a .viruses are not alive .
Answer:
Viruses are tinier than bacteria. In fact, the largest virus is smaller than the smallest bacterium. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host.
So life itself is an emergent, complex state, but it is made from the same fundamental, physical building blocks that constitute a virus. Approached from this perspective, viruses, though not fully alive, may be thought of as being more than inert matter: they verge on life.

What were the Himalayan Mountains formed by?
The gravity of the Sun pulling on Earth's crust
Erosion over time
A meteor hitting Asia
The movement of Earth's crust
Answer: The movement of the Earth's crust
Explanation:
The movement of the earth's crust is responsible for the formation of the Himalayas. The Himalayas ranges and the Tibetan plateau is formed by the result of the collision between the Indian plate and the Eurasian plate which started 50 million years ago.
This leads to the movement of the earth's crust which aimed to the formation of the mountains.
The movement of the plates lead to the movement of the earth's crust which lead to the formation of Himalayan mountain.
How does a hormone like ADH only know to have an effect on the cells of the kidney and nowhere else?
Answer:
Vasopressin or antidiuretic hormone (ADH) or arginine vasopressin (AVP) is a nonapeptide synthesized in the hypothalamus. Science has known it to play essential roles in the control of the body’s osmotic balance, blood pressure regulation, sodium homeostasis, and kidney functioning. Given its vital role in multiple functions, it is no surprise that ADH is of great clinical significance. ADH primarily affects the ability of the kidney to reabsorb water; when present, ADH induces expression of water transport proteins in the late distal tubule and collecting duct to increase water reabsorption. Several disease states arise when the body loses control of ADH secretion or responds to its presence.

Which is not a product of photosynthesis?
water
oxygen
glucose
nitrogen
Answer:
nitrogen
Explanation:
Plants use photosynthesis by taking in water and carbon dioxide and releasing oxygen while consuming food (glucose) for itself. Therefore, your answer is nitrogen. No nitrogen is created during this process
Answer:
Nitrogen
Explanation:
Photosynthesis is a process used by autotrophs and producers, like plants, algae, and some bacteria. In this process, water, carbon dioxide and light energy from the sun are turned into glucose and oxygen. The glucose becomes food for the organism, and the oxygen becomes the waste product.
There is no nitrogen involved in photosynthesis. It is not created, and therefore is not a product. The best answer choice is nitrogen
Se efectúa un experimento en el que a la planta 1 se le suministra CO2 normal pero agua que contiene átomos de oxígeno radiactivos. A la planta 2 se le suministra agua normal pero CO2 que contiene átomos radiactivos de oxígeno. Se permite que ambas plantas efectúen fotosíntesis y se mide la radiactividad del oxígeno gaseoso y los azúcares producidos. Qué planta esperarías que produzca azúcares radiactivos y cuál oxígeno radiactivo, por qué?
Answer:
The Oxygen liberated in photosynthesis comes from photolysis of water.
The CHO formed from Calvin Cycle during photosynthesis comes from reduction of CO2 with H+ of photolysis of water.
Therefore,since Plant 1 contains labeled Oxygen(from water) it will give radioactive Oxygen as the byproduct of its photosynthesis. It CHO is normal.
However,Plant 2, will contain radioactive CHO,because its radioactive CO2 will be reduced by H+ from photolysis of water to form radioactive labeled carbohydrate(CHO)

What types of enzymes play a catalytic role in the regulation pathway of ubiquitination?
Answer:
ubiquitin activating enzyme ( E1), a ubiquitin conjugating enzyme (E2), and a ubiquitin ligase (E3).
Explanation:
In ubiquitination, ubiquitin (regulatory protein) attach to a protein to inactivate it and targets a protein for degradation via the proteasome.
There are three enzymes sequentially catalyse the process of ubiquitination that includes ubiquitin activating enzyme ( E1), a ubiquitin conjugating enzyme (E2), and a ubiquitin ligase (E3).
The E1 activates ubiquitin by forming a thiol ester bond between the C terminus of ubiquitin and the active cysteine of the E1 which is an ATP dependent step.
The activated ubiquitin then tranferred to cysteine of E2 which along with E3 transfers the ubiquitin to a lysine residue in the target protein.
Hence, all three ubiquitin activating enzyme ( E1), a ubiquitin conjugating enzyme (E2), and a ubiquitin ligase (E3) enzymes sequentially catalyse the process of ubiquitination.

A) 6O12H6C
B) 6C12H6O
C) O6H12C6
D) C6H12O6
The correct answer is D) C6H12O6
Explanation:
According to the question, Miles is trying to write down the chemical equation for Photosynthesis. Photosynthesis is a chemical reaction that cells of autotrophic organisms undergo in the presence of sunlight to produce their food. Photosynthesis, which occurs in the Chloroplast, involves the chemical reaction between Carbondioxide (CO2) and water (H2O) to produce a sugar called glucose (C6H12O6) and oxygen gas (O2).
The food is synthesized as glucose, which is a monosaccharide (simple carbohydrate) that cells absorb in order to synthesize energy (ATP).
The overall equation of photosynthesis is as follows:
C02 + H2O ---light---> C6H12O6 + 6O2
The diagram in the question, although incomplete, depicts the sugar (glucose) component of the equation. The correct chemical formula for this sugar is written as: C6H12O6
