A running back is running down the field and two people on the opposing team run towards him. One person is running east with a force of 250 N. The other person is running west with 250 N of force . They all collide at the same time. Show the forces affecting the running back.
Are the forces balanced or unbalanced?
Net force = ?
Answers
Given our understanding of the laws of physics, we can confirm that the Net force affecting the running back (ignoring gravity and its complementary force) is that of 500N and balanced.
In physics, we can say that the net forces being applied to an object are balanced when the forces are
Equal in sizeApplied in opposite directionsApplied at the same time.The question states that the running back collides with two members of the opposing team at the same time. This, coupled with the fact that the opposing team members are described to arrive on exactly opposite sides, we can say that the forces being applied to the running back are indeed balanced.
Furthermore, since the forces are 250N in size each, we can confirm that the net force applied to the running back is 500N. To this, we would normally add the force of gravity, however, in order to do this, we would need the weight of the running back, that is, data that is not provided.

Answers
We have that for the Question "since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4" it can be said that
Why the Kirby bauer test require that the agar have a ph of 7.4 is because while agents may be in excessive activity, given a scenario that the pH is to exceed 7.4 the results might inverse.
From the question we are told
since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4
Generally
Agar has a ph value that should exist between 7.2 and 7.4 within a room temperature,given it solidifies and this should be when initially prepared
Therefore
Why the Kirby bauer test require that the agar have a ph of 7.4 is because
while agents may be in excessive activity, given a scenario that the pH is to exceed 7.4 the results might inverse.

Answers
Answer: If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will D. complete the cycle and divide. G1 checkpoint occurs between the G1 and S phase of the cell cycle. When the cell is grown sufficiently and produces all components of DNA replication it enters in the S phase.
If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide.
What is cell cycle?The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells.
Moreover, a cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material.

Energy pyhamids, otherwise known as trophic level diagrams, are used to represent the flow of
energy through an ecosystem. An organisms trophic level indicates the organism's position in
the sequence of energy transfers. The bottom, or base, of an energy pyramid is a position
always held by the producers and represents (by far) the largest percentage of biomass for
the food web. The need for such a large biomass of producers is to support the energy
needs for all the organisms at higher trophic levels. Draw and label an energy pyramid for the
following 1 hectare of farmland:
• 30,000,000 MJ of Sunlight (solar energy) reaches ground level during a 150-day growing
season
• 52,164 MJ of energy is stored in the soybeans grown on the hectare of land
1,645 MJ of energy is stored in edible beef by cattlewho eat the soybeans
Answers
From the total energy that reaches the ground, 1% is used by producers. The energy transference in the trophic web follows the 10% rule, in which each level uses 10% of the energy stored by the anterior level.
---------------------------------------
Only 1% of the total solar energy that reaches the ground is used by producers, who occupy the first trophic level. From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment. At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The progressive reduction of energy determines the number of trophic levels (4 or 5).If 30,000,000 MJ of Sunlight (solar energy) reaches ground, then only 30,000 MJ can be absorbed by primary producers.
5,216.4 MJ from 52,164 MJ of energy stored in the soybeans, are used by cattle.
1,645 MJ of energy is stored in edible beef by cattle who eat the soybeans.
164.5 MJ of this energy is tranferred to the following trophic level.

What is reproduction?
Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique.
In asexual reproduction, one parent copies itself to form a genetically identical offspring. Sea turtles are an example of an animal that reproduces sexually, a volvox (green algae) is an example of an organism that reproduces asexually, and a brittle star can reproduce in either way.
Reproduction is the process by which new organisms (offsprings) are produced from organisms of the same kind.

Answers
Answer:
Explanation:
The primary purpose of the systemic circuit is for blood to release carbon dioxide and pick up oxygen
The primary purpose of the pulmonary circuit is for the blood to release carbon dioxide and pick up oxygen.
What is pulmonary system?It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs.
Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.
The respiratory system makes it possible for the body to take in oxygen and expel carbon dioxide.
The nose and mouth are the beginning of the respiratory system, which continues through the airways and lungs.
The pulmonary circulation serves a variety of crucial purposes. Its main job is to exchange gases across the alveolar membrane.
This ultimately results in oxygenated blood being delivered to the rest of the body and carbon dioxide being removed from the bloodstream.
Thus, the pulmonary circuit's main function is to allow the blood to absorb oxygen and release carbon dioxide.

What molecules are required for the Calvin cycle? (3 answers)
Answers
Answer:After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build food in the form of carbohydrate molecules. The carbohydrate molecules made will have a backbone of carbon atoms. Where does the carbon come from? The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.
Explanation:The Interworkings of the Calvin Cycle
In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle. Others call it the Calvin-Benson cycle to include the name of another scientist involved in its discovery (Figure 5.14).
This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
