8 The luteal phase spans from
days 1-5
days 6-14
days 15-28
none of the above
Answer:
The correct answer is - None of the above.
Explanation:
The luteal phase is the stage of the menstrual cycle in which the lining of the uterus or uterine walls normally gets thicker for pregnancy. this phase begins after ovulation and ends just before the periods start. If pregnancy does not take place wall starts to shed.
A normal luteal phase spans from 12 to 14 days, however, it can last anywhere between 11 to 17 days. Less than 10 consider as a shorter luteal phase and more than 17 is a longer luteal phase.

Potential Energy on the way up the rollercoaster
Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.

Which makes a bigger difference: a 100 kg increase in the mass or a 100 meter/sec rise in velocity?
An increase in mass of 100 kg. No, it is not true that an object moves faster quickly the less mass it has, as your example demonstrates very clearly. Another illustration: a snail moves more slowly than a rocket but weighs much less. Thus option A is correct.
What mass makes a bigger difference compare to velocity?The heavier (denser) object will fall quicker if two identically sized but made of different materials objects are present. This is because both objects will experience the same drag and buoyancy forces, but the heavier object will experience a stronger gravitational pull.
The less an object accelerates when a certain force is applied, the more mass it has. For instance, the acceleration is halved for a given force when the mass of an object is twice.
Therefore, a 100 kg increase in the mass. No, as your example clearly shows, it is not true that an object travels more quickly the less mass it possesses. Another example: a snail travels slower than a rocket but is considerably lighter.

are all experiments designed the same way?
Answer:
Design of Experiments (DOE) is also referred to as Designed Experiments or Experimental Design - all of the terms have the same meaning. Experimental design can be used at the point of greatest leverage to reduce design costs by speeding up the design process, reducing late engineering design changes, and reducing product material and labor complexity.

Explain the events of the sliding filament theory of skeletal muscle contraction beginning with immediately after the release of Ca++ from the sarcoplasmic reticulum and ending at the end of one cross bridge cycle.
Answer:
According to the sliding filament theory, the myosin (thick) filaments of muscle fibers slide past the actin (thin) filaments during muscle contraction, while the two groups of filaments remain at relatively constant length.
Explanation:
The sarcoplasmic reticulum stimulated to release calcium ions.
Calcium ions bind to troponin. ...
Cross bridges (on myosin) pull on actin (power stroke) ...
Cross bridge detaches from binding sites on actin.
Muscle fiber lengthens & relaxes.

Explain the fully developed (Bisporic embryo sac and Tetrasporic embryo sac ) types of embryo sac? in plant
Answer: Embryo sac is the megaspore mother cell.
Explanation:
The bisporic embryo sac can be defined as the comprises of the nuclei that is obtained from two units of the megaspore tetrad on the other hand, the tetrasporic embryo sac comprises of four units of megaspore tetrad. The megaspore mother cell undergoes meiosis to produce megaspore tetrad or four haploid megaspores.

How are ATP molecules important in plants?
Answer:
D
Explanation:
ATP molecules are important in plants as ATP molecules provide energy for the synthesis of carbohydrates.
What are the functions of ATP molecules?Adenosine triphosphate is an organic compound that provides energy to drive many processes in living cells, such as muscle contraction, nerve impulse propagation, condensate dissolution, and chemical synthesis.
Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.
Adenosine triphosphate (ATP) are energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
