which answer best explains how certain patterns of histone acetylation or dna methylation could influence whether a cell became a muscle cell or a brain cell?

Answers

Answer 1
Answer: Cells have unique characteristics wherein each develop a specific function determined by the activation of certain DNA sequences to generate this specific cell into its supposed design, this is why cell specialization exists. 

Hence, these cells can be directly identified with their morphological structures and the DNA sequences they posses.

Which of the following is correct for the effect of linkage on recombination?It increases the percentage of recombinants.
It results in 50% recombinants.
It reduces the percentage of recombinants.

Answers

The answer for your following question would be : C. It reduces the percentage of  recombinants. From the following options, The one that is correct for the effect of linkage on recombination is : it reduces the percentage of recombinants

Answer:

It reduces the percentage of recombinants.

Explanation:

The independent assortment of genes gives rise to new gene combination and recombinants. Linkage refers to the tendency of two genes present in the vicinity on the same chromosome to get transmitted together.  

Since the linked genes are inherited together, they do not exhibit independent assortment. Due to the absence of independent assortment in linked genes, more of parental types and lesser recombinants are formed.  

Plant cells undergo photosynthesis to produce glucose, a usable form of chemical energy. The energy produced by plants becomes the base of an energy pyramid. Given the situation seen above, what reactant is missing in order for photosynthesis to occurA) water 
B) ozone 
C) chlorophyll 
D) radiant energy

Answers

Water is the key reactant missing, Radiant energy is not needed as plants can produce energy/glucose in both light dependent and light independent reactions, Chlorophyll Is the organelle what is used to produce the atpĀ 
Photosynthesis: water + carbon dioxide + Sunlight = Glucose + oxygen.

what does 50 percent humidity mean? A. The air contains 50 percent of the moisture it can hold before precipitation occurs B. There is a 50 percent change of precipitation C. The air temperature is 50 degrees celsius D. There is a 50 percent chance of a thunderstorm occurring

Answers

Answer: The correct answer is-

A. The air contains 50 percent of the moisture it can hold before precipitation occurs.

Humidity can be described as the presence of gaseous state of water (that is water vapor) in the atmosphere or air.

It indicates the chances of occurance of precipitation or fog in the weather.

50% humidity represents the relative humidity, indicating that air is 50% saturated with moisture, which could be held by air before precipitation occurs .


50% humidity indicates that before precipitation the air withholds 50% moisture and it is known as relative humidity.

Further Explanation:

The amount of moisture the air contains is defined by humidity. A particular amount of water vapor is present in the air which depends on the temperature of the air. The warmer air contains holds more water within it. The relative humidity is defined as the content of water vapor found in the air in relation to the amount it can actually hold. When the relative humidity is low, it implies that the air can comparatively withhold more moisture at that particular temperature and this makes the air dry.

For example, it is estimated that a cubic meter of air is able to hold 18grams of water as a maximum value at 20 degrees C. Similarly, at 25 degrees C, 22 grams of water can be held by the air. Therefore, if 22 grams of water is contained in a cubic meter of air at 25 degrees C, then there is 100% relative humidity. But if the same amount of air holds 11 grams of water, the relative humidity is said to be 50%.

The relative humidity plays a major role in maintaining our level of comfort. A 100% relative humidity means that there will be no evaporation of water and the moisture has fully saturated the air. For cooling, the body requires to evaporate the moisture from the skin. A low relative humidity enables the body to release moisture and make the body cooler. At 100% relative humidity, the body feels much hotter as compared to the actual temperature. This is because the body does not sweat to evaporate due to high humidity.

Protists from which of the following taxonomic groups are most likely to lead to paralytic shellfish poisoning? Protists from which of the following taxonomic groups are most likely to lead to paralytic shellfish poisoning? A. Toxoplasma
B. Plasmodium
C. Euglena
D. Giardia
E. Dinoflagellata

Answers

Paralytic shellfish poisoning.

Explanation:

The taxonomic group which is more likely to cause shellfish poisoning is :

E. Dinoflagellata.

Paralytic shell fish poisoning is a serious food poisoning caused by consuming poisonous shell fishes. The shell fish become toxic due to contamination by dinoflagellates that secrete harmful toxins such as cyanides.

Paralytic shellfish poisoning leads to blockage of sodium channel resulting in paralysis of alimentary canal and respiratory muscles in severe case leading to death of the person
