Answer:
The correct answer is -the nervous system is rapid whereas the endocrine is slow and effective on distant target organs.
Explanation:
Both the nervous system and endocrine system are essential and major regulating or controlling systems in an organism. The nervous system ae compared to airmail as it uses nerve stimulus to bring rapid control whereas the endocrine is like pony express as it acts much more slowly.
The nervous system is fast and rapid and required electrochemical stimulus or impulses whereas the endocrine system produces hormones and releases them to the blood which then travels to the target organ and binds to it.
1.Paramecium was found to occupy 20% of the FOV of a microscope at 40X magnification power. How many paramecium can be accommodated within this FOV
Answer:
Five (5)
Explanation:
A total of five (5) paramecia can be accommodated within the FOV.
The field of view of a microscope represents the area of the visible region under the ocular/eyepiece at a specific magnification. In other words, the diameter of the circular area visible through the ocular of the microscope at a specific magnification represents the field of view.
If a paramecium was found to occupy 20% of the total field of view of a microscope at X40 magnification, then the total number of paramecia that can be accommodated within the field would be:
100/20 = 5 paramecia
The number of many paramecium can be accommodated within this FOV
is Five (5)
Given that,
Paramecium was found to occupy 20% of the FOV of a microscope at 40X magnification power.Based on the above information, the calculation is as follows:
[tex]= 100\div 20[/tex]
= 5

Compare the reactants and products in the chemical equations below. Which statement best describes the relation between matter and energy?
Answer and Explanation:
Chemical reactions are very complex processes which include the collision of molecules. During the chemical reactions, bonds between the breakdown of the atom and transformed in new ways. The chemical compounds that react together during the chemical reactions are called reactants, shown on the left side of the equation. They are broken down during the reaction and used as the reaction progresses. The chemical compounds that are formed from the rearrangement and breakdown of the reactants are called products. The products are shown on the right side of the chemical equation. As compare to the reactants, the products are more stable molecules. For example, in the reaction between H2SO4 and Zn, these two chemicals are the reactants, while ZnSO4 and H2 are the chemical reaction products.
Zn + H2SO4 ZnSO4 + H2
(Reactants) (Products)
The matter is a material that everything is made of matter. A property that matter has is known as energy. The same quantity of matter can have a diverse quantity of energy. Both energy and matter are identical. For example, if we add some energy into an ice cube, it will turn into liquid. After that, if we add more energy, liquid will turns into steam.
What are the conditions necessary for an annular solar eclipse?
A. Moon in perigee orbit; Moon moves a direct line between Sun and Earth; Moon in full moon phase.
B. Moon in perigee orbit; Moon moves a direct line between Sun and Earth; Moon in new moon phase.
C. Moon in apogee orbit; Moon moves a direct line between Sun and Earth; Moon in new moon phase.
D. Moon in perigee orbit; Earth a direct line between Sun and Moon; Moon in full moon phase.
Answer:
B
Explanation:
An annular eclipse occurs when the Sun and Moon are exactly in line with the Earth, but the apparent size of the Moon is smaller than that of the Sun. Hence the Sun appears as a very bright ring, or annulus, surrounding the dark disk of the Moon.

Explanation:
Sickle cell anemia and albinism are both recessive traits in humans. Imagine that a couple, already pregnant with fraternal twins, has just learned that they (the couple) are both heterozygous for both of these traits. As the couple's genetic counselor, the couple asks you what is the probability of having both of the twins be albino and have sickle-cell anemia.
Answer:
81/256
Explanation:
By doing a test cross of albinism and sickle cell anemia you'll see that the probability that one child is unaffected by either conditions will be 9/16. Both children would be 9/16 * 9/16.
Since fraternal twins are developed from two separate fertilization events the probability chance will be independent.

Describe why the amount of light available to the Chlorella culture might affect the growth dynamics of the alga.
Answer:
See the answer below
Explanation:
The amount of light available to Chlorella culture might affect the growth dynamics of the alga because the light is an important factor necessary for the synthesis of carbohydrates and other important molecules in the body of the organism.
The process of synthesizing carbohydrates is termed photosynthesis and during this process, the energy of light is used to excite the photosystem of the chlorophyll of the organism, leading to the release of electrons whose energy is used to synthesize an energy molecule that is utilized in the latter part of the photosynthetic process. The entire process of photosynthesis can be summarised as an equation below:
[tex]6CO_2 + 6H_2O + light --> C_6H_1_2O_6 + 6O_2[/tex]
The manufactured carbohydrates act as food for the organism and are broken down during respiration to release energy necessary to drive metabolic processes that bring about growth and development.
Hence, the amount of light is an important factor that might affect the growth dynamics of all green plants, including the Chlorella.
The amount of light available to the Chlorella culture affect the growth dynamics of the alga because of photosynthesis.
Chlorella is an alga means it is an autotrophic organism that produce food by using the sunlight.
In the absence of light, Chlorella will not be able to survive in the culture.In presence of low light, Chlorella will grow slowly due to low production of food.In presence high intensity light, Chlorella will grow faster.Therefore, the amount of light available to the Chlorella culture affect the growth dynamics of the alga because of photosynthesis.

In sweet pea plants, purple flower color is dominant over red flower color and long pollen grain shape is dominant over round pollen grain shape. Two sweet pea plants that we heterozygous for both flower color and pollen grain shape are crossed with one another. A geneticistis surprised to observe that there are fewer round purple offspring and long red offspring than were predicted by the 9:3:3:1 expected phenotypie ratio Which of the following statements provides the most reasonable prediction to account for the deviation from the expected results?
A) in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked
B) In sweet pea plants the genes for flower color and for pollen grain shape both exhibit codominance
C) Several mutations occurred spontaneously producing a deviation from the expected phenotypic ratio of the offspring
D) The genes for flower color and pollen grain shape are inherited independently because of the law of independent assortment
Answer:
The correct answer is - option A) in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked.
Explanation:
In this given case the result of phenotypes are not as expected and does not follow the law of independent assortment presented by Mendel. It appears to be the case of genetic linkage as it is not following the mendelian law by producing fewer round purple offspring and long red offspring which do not satisfy the expected mendelian ratio of 9:3:3:1. Mutation can lead to failure in producing proteins but could not affect the phenotypic ratio of the plant.
Thus, the correct answer is - option A.
Medel was the Father of Genetics, who gave the laws on independent assortment, dominance, and segregation of the genes.
However, there are some exception that violates these laws, such as genetic linkage is one of the exceptions that violates the law of independent assortment.
The correct answer is:
Option A. in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked
In the given data, the results can be interpreted as:
The Law of independent assortment states that the two or more alleles of different genes are assorted independently. In the given example, the genetic linkage occurs, which does not follow the ratio of 9:3:3:1. The genetic linkage does not follow the law of independent assortment, which results in fewer purple offspring.Thus, mutation can cause the failure of Mendel laws and can affect the phenotypic traits of an organism.
Therefore, Option A is correct.

Why are urine samples kept in a refrigerator before testing?
Answer:
Urine refrigeration preservation maintains the sample in the ACS chemical analysis, cellularity and bacteriuria
Explanation:
Tests with high diagnosis and prognostic importance in clinical practice include urinary irregular constituents and sediment (ACS). If it is not possible to analyze ACS within two hours of processing, the sample must be retained to prevent pre-analytical interferences. Cooling is due to its economic productivity the most commonly used technique. In comparison, relative to chemical preservation, it poses fewer discomforts.

For a particular plant, red flowers (A) are dominant over yellow flowers (a). An initial cross was made between a plant that was true-breeding for red flowers and another plant true-breeding for yellow flowers. F1 progeny, all having red flowers, were allowed to self- pollinate and form seeds, which were then planted to generate F2 progeny. Pollen from all the resulting F2 plants was pooled and used to fertilize true-breeding yellow plants. What proportion of the progeny resulting from this cross would be expected to have yellow flowers
Answer:
The correct answer would be - 1 out of 4 or 25% offspring would be expected to have yellow flowers
Explanation:
Red flowers are dominant over the yellow flower, initially, a cross was made between true-breeding red and true-breeding of yellow flowers
Red flower plant gametes, a and a and red plants gamete would be A and A.
so,
A A
a Aa Aa
a Aa Aa
in this cross, all the offspring are red as they have a heterozygous genotype. Now self-pollinating these F1 generation offsprings, gametes would be A and a for both parents:
A a
A AA Aa
a Aa aa
in the f2 generation, there is only 25% of offsprings are yellow flowers.

67. Obligate anaerobes
68. Aerotolerant anaerobes
69. pH
70 media nutrient density
71. agar concentration
72. extremophiles
Explanation:
Anaerobes are microorganisms which do not require oxygen for their metabolic activities. The types of anaerobes based on metabolism are: obligate anaerobes; facultative anaerobes ; and aerotolerant anaerobes.
Some bacteria are anaerobes.
67. Obligate anaerobes do not require oxygen at all for their metabolism. They die in the presence of oxygen.
68. Aerotolerant anaerobes do not require oxygen as well but can also tolerate oxygen. they are unaffected by the presence or absence of oxygen
69. The pH of the medium affects the growth of bacteria. When pH becomes too low or too high, bacteria colonies begin to die.
70. when the nutrient concentration is high, growth rate of bacteria colony increases, but when it is low, bacteria colony growth decreases.
71. agar concentration limits the growth of bacteria colony. When the agar is very concentrated, that is the medium is hard, the bacteria colony is limited in their ability to move and vice versa.
72. Extremophiles is the name given to archaea that thrive in extreme conditions of temperature and pH. For example, the archaeal Methanopyrus kandleri strain 116 grows at 122 °C while the genus Picrophilus e.g., Picrophilus torridus has the ability to grow at a pH of 0.06.
