What is the best explanation for the difference in shape between the two drops shown below

Answer:

directional selection, stabilizing selection

Explanation:

Directional selection is a type of natural selection that favors one extreme phenotype over other phenotypes, thereby modifying allele frequency in the direction of the favored phenotype. This type of positive selection is the main cause of phenotypic diversification. In the USA, the environment created a selection pressure that favored individuals that don't have the defective sickle-cell allele, thereby reducing its frequency in this population. Stabilizing selection, also known as balancing selection, is a type of natural selection where the most common phenotype is selected in the population, thus predominating in future generations. In equatorial Africa, the defective sickle-cell allele is present in a high frequency because individuals that are heterozygous for this allele are less susceptible to malaria, and therefore balancing selection should maintain this allele in the African population.

What are the reproductive systems of insects?

Insects that’s is female can make eggs, receive and store sperm, manipulate sperm from different males. They can also lay eggs of course. Insects reproductive systems are made of a pair of ovaries, accessory glands, one or maybe even more spermathecae, and lastly ducts connecting these parts. The ducts and spermathecae are line with a cuticle.

Answer:

c. polyarthritis.

Explanation:

Rheumatic fever is an inflammatory disease that may affect different parts of the body including joints, heart, brain, and skin. It is a rare disease observed after a bacterial throat infection caused by Streptococcus (group A). The most common signs of this disease include swollen and/or tender joints (i.e., polyarthritis), especially in wrists, knees, elbows or ankles, fever, fatigue, pain in the chest, breathlessness, palpitations, etc. Rheumatic fever needs to be treated by antibiotics to eliminate group A Streptococcus infections.

Answer:

The scheme most often used currently divides all living organisms into five kingdoms: Monera (bacteria), Protista, Fungi, Plantae, and Animalia. This coexisted with a scheme dividing life into two main divisions: the Prokaryotae (bacteria, etc.) and the Eukaryotae (animals, plants, fungi, and protists).

Answer: D

Explanation: it’s the size of the sediments

Answer:

A. Tap water is a homogenous mixture and distilled water is a pure substance.

Explanation:

Tap water can be classified as a homogeneous mixture because it contains equal amounts of dissolved minerals and other chemicals that are even throughout the mixture.

In the other hand, distilled water is classified as a pure substance because it contains definite amount of atoms of elements and unique chemical properties that forms water.

Answer:

The two structures most likely to be observed by the scientist when looking at a type of bacteria under the microscope are cell wall and vacuole (option C).

Explanation:

Bacteria are prokaryotic organisms that lack a nucleus, most of the organelles, and whose DNA is dispersed in the cytoplasm. Some types of bacteria have a plasma membrane surrounded by a cell wall, and may be equipped with vacuoles to perform their functions.

It is very likely that two structures that are most likely to be differentiated when a type of bacteria is observed under the microscope are the cell wall and the vacuole, according with information above.

The other options are not correct because:

    A and D. Bacteria lack a nucleus.

    A and B. Bacterial DNA is dispersed in the cytoplasm and is very difficult to observe under the microscope.

Answer:

cell wall vacuole

Answer: Alarm

Explanation:

When equipment malfunctions, an alarm should be initiated to bring the malfunction to the attention of the relevant personnel.

This will ensure that whatever adverse effects the malfunction could have caused is mitigated and the machine can be attended to on time to prevent further damage.

Agricultural technology has evolved over time, with significant leaps during the agricultural and green revolutions.

Agriculture has been one of the sustainers (along with hunting) of early men and as such, has seen gradual development with time. Man has always been looking for better ways to do things in order to achieve outcomes.

With the era of the agricultural revolution, there was a huge transition of humans from the primitive lifestyle of hunting and fruit gatherings to that of agricultural settlements. Better ways to carry out crop production started receiving huge attention. from there, hand-made agricultural equipment started surfacing.

The green revolution has agriculture receiving utmost attention in terms of technological innovations. Farm machinery, agrochemicals, etc, started coming up with the result being a massive increase in crop production and general outputs.

Answer:

Oxygen

Explanation:

-How fast the heart beats depends on the body's need for oxygen-rich blood. At rest, the SA node causes your heart to beat about 50 to 100 times each minute. During activity or excitement, your body needs more oxygen-rich blood; the heart rate rises to well over 100 beats per minute.

-The heart, like any organ, requires blood for oxygen and other nutrients so it can do its work. The heart does not gather oxygen or nutrients from the blood flowing inside it. Instead, it receives blood from coronary arteries that eventually carry blood into the heart muscle.

Answer:

stabilizing selection

Answer: depending on viscosity, mass and velocity of impact, if droplet integrity is maintained, as velocity increases, diameter will increase from

Approximately d*sqrt(2) to 2*sqrt(d^3/6a) where d is original diameter and a is thickness when the droplet flattens into a disc.

Explanation:

This applies generally to any liquid droplet, which by inference falls and impacts a solid surface. The impact force is mgh where m= mass, g= acceleration due to gravity, h= initial height.

A liquid droplet deforms on impact. Assume the drop is sperical, then the deformation distance, d= diameter of the droplet then the average impact force = mgh/d.

The droplet may spread, splash or bounce, depending on viscosity and force, which depends on mass and velocity immediately before impact.

All than can be said is that if the droplet maintains integrity it could achieve the shape of half a highly flattened oblate spheroid. Approximating this with a flattened disc of thickness a, and an original volume of 4/3pi(d/2)^3, the volume as a disc =a*pi*r^2 so the horizontal diameter = 2*sqrt(d^3/6a)

It is not really possible from the available data to determine whether the droplet would remain its integrity, but at sufficiently low force/velocity, the droplet could retain a near-hemispherical shape, giving a horizontal diameter of the hemisphere = d*sqrt(2)

As velocity increases, if integrity is maintained, the diameter will increase from the second approximation to the first

Answer:

1) Create a hypothisis 2) Create experiment 3) collect data 4) write conclusion

The four steps that a scientist uses to solve a problem are creating hypothesis, experiment, data sorting and writing conclusion.

A hypothesis is an elaboration posited for a characteristic. The scientific technique requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.

Scientists typically base scientific hypotheses on previous findings that cannot be adequately explained by existing scientific theories.

Any process that co-ordinate system data into some defined order to make it simpler to understand, analyze, or visualize is referred to as data sorting.

The conclusion is the final section of an academic essay. The conclusion should restate your response to the question and briefly summarize key points. It does not contain any new points or information.

A scientist solves a problem by developing a hypothesis, conducting an experiment, sorting data, and writing a conclusion.

Thus, by using these steps, scientist can come to an end for the problem.
