Contact [7]
<span>The correct answer is that he has injured one of the tendons or ligaments that help keep his knee in place, connecting it to the surrounding muscle and bone. As a result of this injury, his knee is no longer connected to the muscle and bone, thus it wobbled sideways when he started walking. He needs to go to a doctor immediately who can fix his knee so as to prevent further complications - he just needs his knee to be set in place again.</span>

V125BC [204]

Answer:

1) Skull and Vertebral column

2) Meninges

3) Cerebrospinal fluid.

Explanation:

Central Nervous system:

CNS is the abbreviation of Central Nervous system. CNS controls the whole body functions so it is the most important component of the body. CNS consist of two parts 1) Brain and 2) Spinal cord

Both of these organs are very important and hence need to be protected. Nature provided these organs with certain protective mechanisms these includes

1) Skull and Vertebral column:

Skull is present around brain and vertebral column is present around spinal cord. These structure provides mechanical support to soft parts of CNS.

2) Meninges:

These are the membranes that provide antiseptic environment to the brain and hence protect it from microbes and other harmful substances.

3) Cerebrospinal fluid:

This fluid is present inside meninges which nourishes the brain and protect it from mechanical stresses.

A survey reveals that 25 percent of a population of 1,000 individuals have attached earlobes (are homozygous recessive for the t
Mumz [18]

Answer:

d. pxp +2pq

Explanation:

The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:

                           p² + 2pq + q² = 1

where, p = dominant allele

           q = recessive allele

Here,

 p² represents frequency of homozygous dominant genotype

2pq represents frequency of heterozygous genotype

q² represents frequency of homozygous recessive genotype

Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.

Explanation:

  1. All observations and information that scientists perceive and record are called data.
  2. A dependent variable, also known as response variable, defines the treatment/variable that changes in response to the independent variable.
  3. According to the second postulate of the Cell Theory, the cell is the basic structural and functional unit of life.
  4. Cells that perform similar functions are grouped together to form tissues.
  5. An experiment is a controlled setting/test that investigates (proves or disproves) a scientist's hypotheses.
  6. One of the major properties of life is to harvest and convert energy to drive basic cellular processes.
  7. Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.The amount of coke is the independent variable.
  8. Homeostasis is defined as an organism's ability to regulate its internal environment in response to fluctuations in the external environment.
  9. A community is a group of populations (different species) inhabiting one place at one time.
  10. In the scientific method, a good theory generates further hypotheses that can be tested.
  11. Multicellular organisms are composed of more than one cells.
  12. Biology is the scientific study of life. <em>Bio</em> means life and <em>logos</em> means study, thought or reasoning.
  13. An ecosystem is an ecological structure in which both biotic and abiotic factors interact with each other.
  14. According to the second postulate of the Cell Theory, the cell is the basic structural and functional unit of life.
  15. Eukaryotes constitute one entire domain of the tree of life. They are distributed in 4 major kingdoms of life.
  16. A dependent variable, also known as response variable, defines the treatment/variable that changes in response to the independent variable.
  17. Homeostasis is defined as an organism's ability to respond and regulate its internal environment in response to fluctuations in the external environment.
  18. Homeostasis is defined as an organism's ability to respond and regulate its internal environment in response to fluctuations in the external environment.
  19. The experimental and control groups differ in the independent variable as only the experimental group receives the variable or treatment.
  20. Quantitative data is quantifiable, numerical data in which the effects of the independent variable on the response variable can be compared through mathematical and statistical tools.
  21. A good theory is universal,broad in scope and substantiated by a large body of evidence.
  22. A good theory is universal,broad in scope and substantiated by a large body of evidence.
  23. A jungle is a group of a single species of dense vegetation.
  24. An organism is an individual living being composed of cells, tissues, organs and organ systems.
  25. Fungi, being saprophytic in nature are the principal decomposers on Earth.
  26. Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.
  27. A population is a single species of organisms inhabiting a single area at a time.
  28. Organisms of the domain Archaea are known to be extremophiles i.e. organisms that can survive and thrive in harsh environmental conditions.
  29. A hypothesis is a potential explanation for observable phenomena.
  30. The three domains of life: Eukarya (Eukaryotes), Archaea and Bacteria (Prokaryotes).
  31. The three domains of life: Eukarya (Eukaryotes), Archaea and Bacteria (Prokaryotes).
  32. A cell is made up of different organelles performing diverse functions for the cell.
  33. The properties of life include: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.
  34. Each level of the hierarchy of life entails the addition of new properties, complexity and more complex functions.
  35. One of the major properties of life is to harvest and convert energy to drive basic cellular processes.
  36. A well tested and substantiated hypothesis leads to the development of a theory that can further be subjected to experimentation.
  37. An ecosystem is an ecological structure in which both biotic and abiotic factors interact with each other.
  38. Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.
