In a sample of double stranded dna if 27% of the nitrogenous bases are thymine what percentage of nitrogenous bases are cytosine
Answer:
23%
Explanation:
According to Chargaff's law A = T and G = C
T = 27%
A = 27%
27 + 27 = 54
100 - 54 = 46
46/2= 23
So 23%

How many chromosomes are in the cells after they divide? How many chromatids are there?
Answer:
two chromatids
After DNA replication, each chromosome now consists of two physically attached sister chromatids. After chromosome condensation, the chromosomes condense to form compact structures (still made up of two chromatids). As a cell prepares to divide, it must make a copy of each of its chromosomes.

What is the relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C?
Answer:
The amount of moisture air can hold is dependent on its temperature and pressure. The warmer the air the greater the quantity of water vapour it can contain. The air temperature is measured with a normal thermometer this is the Dry-Bulb reading. The actual amount of moisture known as the mixing ratio is measured in grams of water per kilogram of dry air. When air at a certain temperature is saturated it cannot hold any more moisture. The relative humidity of the air is the ratio of the actual amount of moisture in the air to the fully saturated amount.
We can use evaporation to measure the amount of moisture in the air. A wet cloth is placed over the bulb of a thermometer and then air is blown over the cloth causing the water to evaporate. Since evaporation takes up heat, the thermometer will cool to a lower temperature than a thermometer with a dry bulb at the same time and place. The depression in Wet-Bulb temperature allows the humidity to be calculated. If the air is fully saturated (100% relative humidity) the water cannot evaporate, so both the wet and dry bulb temperatures are the same. If the dry and wet bulb temperatures are set to the same value the calculator will show the saturation mixing ratio the amount of water in saturated air at that temperature.
If partly saturated air is cooled without changing its pressure or amount of water vapour, a point is reached when it becomes saturated. The moisture will be given up as dew or ice crystals. This temperature is the Dew Point. This is why condensation will form on a bottle of cold beer, as the air in the vicinity of the bottle is cooled below its dew point. Meteorological reports usually quote the temperature and dew point as well as the station pressure. Moisture content and relative humidity can be calculated from these figures.
The Psychrometer is the name of a device containing both a wet and dry bulb thermometer. This can be a fixed device for meteorology or a handheld sling psychrometer that is often used in air conditioning applications.
Explanation:
The relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C is 45.1%.
Psychrometer:
It is a device that use to calculate the relative humidity and dew. It has two thermometer, one measures the dry temperature while another measures the wet-temperature.
Given here,
Dry-bulb temperature is 26°C
Wet-bulb temperature is 18°C
The difference between temperature of wet and dry bulb is
= 26 - 18 = 8°C
Now compare the temperature difference to the chart given in the
Therefore, the relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C is 45.1%.

how does the mammalian body protect itself against infections
The body defends against infection by increasing the number of certain types of white blood cells (neutrophils and monocytes), which engulf and destroy invading microorganisms. The increase can occur within several hours, largely because white blood cells are released from the bone marrow, where they are made.

The acidity of the water in a stream is indicated by its pH. Historically, a certain stream has had a pH of 6.0. Acid rain has caused the stream's pH to become 4.8. Which statement predicts how the stream's ecosystem will most likely be impacted? A The flow rate of the stream will increase B. The flow rate of the stream will decrease. с The number of fish in the stream will increase. D The number of fish in the stream will decrease.
The statement predicts how the stream's ecosystem will most likely be impacted is the number of fish in the stream will decrease. Thus, option D is correct.
What is the procedure to indicate the pH of the water stream?The acidity of the water in a stream is indicated by its pH. Historically, a certain stream has had a pH of 6.0. Acid rain has caused the stream's pH to become 4.8.The flow rate of the stream will decrease. The number of fish in the stream will increase and the number of fish in the stream will decrease.
Acid rain is a form of rain with high concentration of hydrogen ions and is acidic in nature. pH of these rains is low and pH is the negative logarithmic of hydrogen ion concentration. It is known as power of hydrogen.
The animal which has the lowest value of pH will be able to tolerate the acid rain more and will be last to die. From the tolerance range of the animals, frogs has the lowest pH for survival which is 4 and it can bear more acid rain than the rest of the animals will be the last to die.
Therefore, The statement predicts how the stream's ecosystem will most likely be impacted is the number of fish in the stream will decrease. Thus, option D is correct.

Explanation:
If mutated DNA sequence #1 occurred in a single reproductive cell of a fish that was later fertilized to become an offspring, how might it impact the organism
Answer:
Offspring will have some sort of genetic variation from parent (may be positive or negative or no effect, based on the mutation type)
Explanation:
The reproductive cells pass on the traits from the parents to the offspring.
An organism that is mutated at a single DNA location in a reproductive cell, then that mutation will be passed on to the offspring.
Based on fact, that mutation will lead to some kind of effect in any trait, hence the same trait will be effected because of mutation in the offspring as well
It can also be said that offspring will have some sort of variation from parent (may be positive or negative or no effect, based on the mutation type)
