How is a warm front different from a cold front?

2 answers:

6 0

Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth's surface.

Describe how temperatures above 35 C most likely affect the structure and function of the starch synthase in the particular stra

arlik [135]

Answer:

- It is very likely that temperatures above 35°C will change the structural configuration of the enzyme, denaturing it and preventing it from performing its function.

- According to the information, the most probable consequences for this rice crop is that its starch content will be lower, compared to crops grown at optimal temperatures.

Explanation:

<u>The full question includes this statement</u>:

<em>A rice grain is a fruit that encloses a seed. Most of the dry mass of a rice grain is starch. In rice plants, starch is produced by hydrolyzing sucrose and then linking the released glucose molecules together into starch . The optimal temperature range for starch synthase activity in a particular strain of rice is 27°C - 30°C. The optimal temperature range for sucrose synthase in the strain is 30°C - 35°C.</em>

One of the factors affecting enzyme activity is temperature, according to which an enzyme can make a reaction faster, slower or inhibit the activity of that enzyme.

For a grain of rice to acquire its starch content, the activity of two enzymes is required, sucrose synthase - to obtain glucose from sucrose - and starch synthase, to polymerize glucose into starch (see image).

<h3>In this case, how temperatures above 35°C most likely affect the structure and function of the starch synthase?</h3>

The temperature of 35°C is far above the optimum temperature required for the enzyme to act, so it is possible that a change in the structure of the enzyme will occur or that it will be denatured, preventing the starch synthase from performing its function. One consequence of this is a lower starch synthesis.

<h3>When the average temperature in the growing season is 33°C, what can be predicted about the consequences on the starch content in mature rice grains?</h3>

A temperature of 33°C is outside the range of starch synthase activity -even though it is optimal for sucrose synthase- which would decrease starch synthesis and, because of this, the rice grains in this crop would have less starch content.

Alkaptonuria is an infrequent autosomal recessive condition. It is first noticed in newborns when the urine in their diapers tur

Arisa [49]

Answer:

See the answer below

Explanation:

Let the disorder be represented by the allele a.

Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.

Since the four adults are carriers, their genotypes would be Aa.

Aa x Aa

Progeny: AA 2Aa aa

Probability of being affected = 1/4

Probability of being a carrier = 1/2

Probability of not being affected = 3/4

(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2

(b) The chance that the third child of Sara and James will be free of the condition = 3/4

(c)

(d) If someone has no family history of the disorder, their genotype would be AA.

AA x aa

4 Aa

<em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history </em>= 0

(e)

(f) <em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history</em> = 0

Which type of natural selection occurs when an intermediate phenotype is favored?

klasskru [66]

Answer:

The type of natural selection that occur when intermediate phenotype is favored is called STABILIZING SELECTION.

Explanation:

There are 3 major types of natural selection, these are: stabilizing, directional and diversifying selection.

A stabilizing selection is said to occur when natural selection favors average phenotype by selecting against extreme variations. Stabilizing selection usually leads to decrease in genetic variation of the population concerned.

A good example of stabilizing selection is that of snakes, which have deep green color that blend completely with their environment. This set of snakes will escape from predators more than others in the population, which have color that slightly differ from deep green and which do not blend very well with the environment. Those snakes, whose colour do not blend very well with their environment will get killed more easily by the predators and with time will become extinct while those with colour that blend with the enviroment will survive and produce more offspring.

The extinction of snakes from the population will lead to decrease in genetic variation.

Which of the following is the strongest evidence that protein structure and function are correlated?

kenny6666 [7]

Answer:

Explanation:

To denature a protein is to alter its three dimensional structure. Loss of protein structure consistently correlates with loss of protein function, so it is a strong correlation.

Which statements in this passage about volcanoes do not contain factual errors?

belka [17]

Answer:

The correct answer is option 2. "Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano".

Explanation:

A seismometer is an equipment used by scientists to monitor ground's motion, including the earthquake activity that occurs beneath a volcano. These instruments are useful to predict if a volcanic eruption is imminent. By analyzing the length and strength of the ground's motion occurring during earthquake activity near a volcano, scientist could predict if an eruption is about to take place.
