Which of the following statements about biogeochemical cycles is not true?a. Biogeochemical cycles include living and nonliving elements.
b. The rock cycle is a biogeochemical cycle.
c. Biogeochemical cycles are an important part of the Earth system.
d. Carbon, nitrogen, and oxygen cycles are biogeochemical cycles.

Answers

Answer 1
Answer: The carbon cycle is definitely an example for a biogeochemical cycle -  The nitrogen and oxygen cycles are biogeochemical cycles too! so the last statement is true.

The biogeochemical cycle includes also for example the movement of water which is nonliving, so a) is also true.
The false statement is b) since the rock cycle does not include any biomatter.
Answer 2
Answer:

c. Biogeochemical cycles are an important part of the Earth's system.

What is meant by the biogeochemical cycle?

The biogeochemical cycle is any of the herbalpathways via which critical factors of livingmatter are circulated. The time period biogeochemical is a contraction that refers to the attention of the organic, geological, and chemical factors of each cycle. The generalized carbon cycle.

What are the 4 types of biogeochemical cycles?

  • Water Cycle or Hydrologic Cycle
  • Carbon-Cycle
  • Nitrogen Cycle
  • Oxygen Cycle.

The major virulence factor produced by C. diphtheriae is diphtheria toxin. The production of diphtheria toxin during infection is controlled by a repressor, DtxR. The activity of DtxR is regulated by iron, which acts as a corepressor. During an infection, the levels of iron available in the tissues for use by C. diphtheriae are low. What effect will the decreased iron availability have on the production of diphtheria toxina. The lack of corepressor binding to DtxR will lead to a loss of repression and an increase in the production of toxin.b. The corepressor will not be able to interact with the operator and will cause an increase in the production of toxin.c. The repressor will not be active, therefore toxin production will decrease.d. Without the compressor to interact with the operator, the repressor will stay bound to the promoter leading to a decrease in the amount of toxin.

Electricity is added to recharge a battery. What is added to ADP to form ATP?A second ribose group
A third phosphate group
A third ribose group
A second phosphate group

I'm thinking third phosphate group?

Answers

Electricity is added to recharge a battery. A third phosphate group  is added to ADP to form ATP.

ATP or Adenosine triphosphate contains adenine, ribose and 3 phosphate groups.

ADP is converted to ATP by the following reaction:

ADP+Pi+energy⇄ATP

The analogy between battery and ATP can be explained as ATP is higher energy form and ADP is lower energy form like charged and uncharged form of the battery. When the terminal or third phosphate is removed from the ATP it becomes ADP and releases energy like a battery. The additional phosphate group when added to ADP forms the ATP molecule like the energy spent by the batteries are recharged by putting in additional energy. Here the additional energy is provided by the third phosphate group.

Answer:

The correct answer is B) A third phosphate group.                                

Explanation:

ATP is Adenosine Triphosphate and ADP is Adenosine Diphosphate.

ADP gets converted into ATP in presence of inorganic phosphate and energy, irrespective of whether the energy is obtained from sunlight or from certain exothermic reactions. ATP is converted into ADP, releasing energy and inorganic phosphate.

Which of the following brought about an increase in human populations by increasing the amount of food and medicine available and decreasing the death rate:a. industrial revolution
b. world war ii
c. the internet
d. invention of the car

Answers

A. Is the correct answer. Industrial Revolution made far-reaching developments in history. More food was produced because manual agriculture was replaced by food production through the use of machines. Because of this, people had more time to focus in more technological advancement and improve the quality of life through producing more food and mass producing medicine. Mortality rate was increased because lesser people were getting sick because of medicines becoming readily available. People who were replaced by machines had the time to take care of their families and giving them the proper nourishment.

What are three products first developed for use in space that people now use in their everyday lives?

Answers

Answer:

CCD Technology, actifed tablets and semiconductors

Explanation:

Semiconductors now absolutely used in every electronic device made which earlier were developed in integrated circuits for making reliable electronic devices that were compact and wouldn't fall apart during lift off.

CCD technology was developed to take compact cameras into space which are now sold as digital cameras in every store.

Actifed tablets were developed as a non-drowsy way of combating illness in space which are now sold as an over the counter cold remedy.

A 68-year-old woman who presents after a fall reports progressive difficulty climbing stairs for the past 3 months. She also feels a loss balance when rising from a chair. She has a 5-year history of diabetes mellitus for which she takes metformin. Examination demonstrates intact cranial nerve function; normal sensory examination except for mildly decreased touch and vibration in her toes, normal motor function except for 4+/5 deltoid power and 4+/5 hip power bilaterally, and an inability to stand on her toes. Deep tendon reflexes are 2+ but 1+ at the ankles; plantar responses are flexor; cerebellar function is normal except for mild difficulty with heel-knee-shin testing. She has difficulty rising from a chair without pushing up with her hands. These clinical findings are best explained by dysfunction in which of the following regions of the nervous system?A. anterior horn cellB. muscleC. nerve plexusD. peripheral nerveE. spinal cord

Answers

Answer:

spinal cord and nerve plexus

Explanation:

Faced with this clinical picture, we would be talking about the affection of the spinal cord and the peripheral nerves that sensually perceive the areas of the epithelium, that is, they give the sense of touch, since the patient is diabetic, it could be deduced that the microangiopathies that this generates Chronic disease over time, can affect the irrigation of certain areas and therefore their inventions, due to lack of supply of oxygen and nutrients.

Diabetics are at risk of affecting both upper and lower limbs, because over time they lose the vascularization and winterization of these areas, thus generating infections or pain imperceptible by the patient.

On the other hand then, it would be ideal to say that the spinal cord with the peripheral nerves that innervate the affected areas, and the cerebellum are affected by the lack of balance or spatial disposition of the patient in relation to their body size.
