Answer:

This exercise is incomplete. The response options are as follows:

a) e+ ca+

b) e ca

c) e ca+

d) e+ ca

The answer is c) e ca+ and d) e+ ca

Explanation:

The Punnett square is a diagram used by biologists to calculate the probability that an individual has a particular genotype. In the Punnett square, each of the possible combinations for the expression of the dominant and recessive alleles can be observed. In the case of exercise, since a crossing is not possible in men, these will only help later during the combination of the alleles.

Aleks04 [339]

Answer:

<u>All the substrates are bound to the enzyme</u>, thats why the reaction rate stopped increasing.

Explanation:

Actually an enzyme works by binding a substrate molecule to its active site, producing a product  , resulting in an increase in the rate of reaction.

            Enzyme + substrate = Enzyme + product

Whenever enzymes are added , reaction rate increases as the substrates are being bound to the enzyme's active sites but then occurs a stage where further addition of enzyme cannot increase the reaction rate because all the substrates have bound to the enzyme and <u>there are no substrates left.</u> Hence the reaction rate stopped increasing.

Outline two disadvantages associated with staining procedures. ​
Olenka [21]

Answer:

The main purpose of Negative staining is to study the morphological shape, size and arrangement of the bacteria cells that is difficult to stain. eg: Spirilla. It can also be used to stain cells that are too delicate to be heat-fixed. It is also used to prepare biological samples for electron microscopy.

Secondly, what are the limitations of simple staining? Disadvantages. It does not give much information rather than the morphological characteristics of bacteria. Through simple staining, we cannot classify a particular type of organism.

Regarding this, what is an example of a negative stain?

In a negative staining technique, an acidic, anionic dye is mixed with a cell sample. The dye changes the color of the background, not the cells, causing the cells to stand out. India ink is the classic example of a negative stain.

Why is studying climate change a scientific challenge? ( please be specific and<br> go into depth)
777dan777 [17]

Answer:

Climate change is already happening: temperatures are rising, drought and wildfires are starting to occur more frequently, rainfall patterns are shifting, glaciers and snow are melting and the global mean sea level is rising. These ever-changing trends mean that scientists have to be well acquainted with all this which requires a great deal of understanding and patience.

The political interests in research often limit the results and many a time misleading

Data for climate research is in many instances difficult to access, often at a price, and according to the source and type of data, the formats for retrieval can be very different. In addition, data may not be available for the same time and space scales. There is often an incompatibility between socio-economic and physical data, both necessary for climate modeling efforts because data collection is generally carried out by different agencies for different purposes. This means scientists have to analyze this data as useful and then research on it.
