Sickle cell disease is a hereditary mutation that causes the red blood cells to deform, decreasing their ability to carry oxygen. Based on the image, what kind of mutation occurs to cause sickle cell disease?
a. deletion
b. duplication
c. substitution
d. translocation

Answer:

here's your answer

Explanation:

When buried six feet down, without a coffin, in ordinary soil, an unembalmed adult normally takes eight to twelve years to decompose to a skeleton. However if placed in a coffin the body can take many years longer, depending on type of wood used. For example a solid oak coffin will hughly slow down the process.

Explanation:

A Pure bacterial culture must be grown in sterile tryptophan or peptone broth for 24–48 hours before performing the test. A sterile environment helps to avoid contamination.

When a test is conducted and it shows the presence of a red or red-violet color in the surface alcohol layer it means the result is positive

But when the colour is yellow it indicate negative reaction due to glucose fermentation.

A deviation from two color may also occur when we have an orange color. This colour change is due to the presence of methyl indole

When there is no color change this indicate No decarboxylase which is an enzyme needed for the fermentation reaction.

Color changes are indicator of how successful the reaction was.

Systems of Measurement: there are two main systems of measurement in the world: the Metric (or decimal) system and the US standard system. In each system, there are different units for measuring things like volume and mass.

There are many different units of measurement that apply to different quantities and variables. However, if we are talking about the most basic units of measurement of the International System of Units (SI), they are:

1. The unit of measurement of length or distance is meter (m). It is often used to measure the size or dimensions of an object.

2. The unit of measurement of mass is the kilogram (kg). It is used to determine how much material is present in an object.

Other derived units of the SI system, such as the second for time, the liter for volume, and the newton for force, are all derived from these two basic units: the meter and the kilogram.

B. Two haploid daughter cells

C. Four haploid daughter cells

D. No, they are not the same

E. Gametes

Explanation:

A) Step 1 and Step 2, according to the image attached to this question, depicts the stages of interphase where the REPLICATION of genetic material occurs i.e formation of sister chromatids.

B) Meiosis occurs in two division steps namely meiosis I and meiosis II. Meiosis I, which involves the separation of homologous chromosomes produces TWO haploid daughter cells.

C). However, in meiosis II, sister chromatids separate to produce FOUR haploid daughter cells.

D) The cells in step 4 are not all the same due to a process called CROSSING OVER, which occurs in the Prophase of meiosis I. Crossing over exchanges chromosomal segments between two non-sister chromatids of homologous chromosomes as seen in the color of the images attached.

E) The four daughter cells produced in step 4 will mature into GAMETES, which will be used in sexual reproduction.

Answer:

D Species

Explanation:

Living organisms have been organized into groups using the Kingdom to Species classification. Kingdom level represents the least specific while Species level represents the most specific. Prior to the discovery of DNA, classification of organisms has been based on structural similarities i.e. organisms that look similar are classified into the same species.

However, the discovery of DNA, put a stop to the erroneous classification of organisms based on structural similarities as there were many exceptions to this. Since members of the same species have a nearly identical DNA, it is used to divide its organisms based on DNA sequences

instead of structural similarities.

Explanation:

Answer: Exceeding threshold depolarization at the trigger zone decreases the likelihood of generation of an action potential.

Explanation:

Exceeding threshold depolarization at the trigger zone decreases the likelihood of the generation of an action potential.

Excessive depolarization at the trigger zone reduces the likelihood of an action potential being generated. The amplitude of the action potential decreases with distance. The number of action potentials increases as the frequency of stimulation to the trigger zone increases.

Because the potassium channels within the cell membrane are delayed, any additional sodium entry activates an increasing number of voltage-gated sodium channels. Depolarization above the threshold causes an increase in Na conductance sufficient for inward sodium movement to instantly swamp outward potassium movement.

Therefore, Excessive depolarization at the trigger zone reduces the likelihood of an action potential being generated.

Amount of growth

Opacity/clarity of colonies

Color of colonies

Shape and /or pattern of growth

Explanation:

An agar plate is a Petri dish containing agar as a solid growth medium supplied with nutrients (i.e., an enriched medium), which enable to culture different microbes ranging from fungi to bacteria. Colony morphology is a widely used approach to describe the unique features of bacteria colonies growing on agar media. These colony features include, among others, shape (round, circular, punctiform, irregular), elevations/depressions (convex, concave, flat), textures (dry, moist, crusty, dull, shiny, mucoid, friable, rough), colors (cream, white, purple, gray, red, green, yellow, blue), etc.

The observation that could be made regarding the growth over nutrient agar would be:

C). Amount of growth

D). Opacity/clarity of colonies

E). Color of colonies

G). Shape and/or pattern of growth.

Answer:

b

Explanation:

reason why is because blowing through a straw demonstrates air so when you blow it against sand or dirt it blows pieces of soil or sand away and in different areas.

Blow into a drinking straw over the sand which demonstrate wind erosion using this model. So, the correct option is (B).

Wind erosion is defined as the natural process that moves soil from one place to another by wind energy which can cause significant economic and environmental damage.

It is a major cause of land degradation in arid and semi-arid grasslands, which is one of the processes leading to desertification. Significant wind erosion occurs when strong winds blow on light textured soils that have been heavily grazed during periods of drought.

It can happen anytime and anywhere when the wind blows which can happen in any area where sand or soil is not compacted or is of fine grained nature. Wind erosion not only destroys the land by drying out the soil and depleting the land's nutrients but also results in air pollution.

Thus, blowing into a drinking straw over the sand which demonstrate wind erosion using this model. So, the correct option is (B).
