Describe artificial selection, and explain how it is different from natural selection.

Answers

Answer 1

Answer:

Starting with natural selection, the most robust and most intelligent animals survive over the weakest. The weak animals eventually die off because they can't keep up with nature. Artificial selection isn't natural; certain species are being targeted on purpose and decide whether to stay alive or not. At this point, it is not at all about whether the species can survive or not because it's most likely being protected.

Which forms as a result of compressional stress?
anticline and syncline
normal fault
strike-slip fault
fault-block mountain

Answers

Anticline and syncline forms as a result of compressional stress. Thus, the correct option is A.

What is anticline ?

Folds known as anticlines occur when formerly horizontal strata have been folded upward and the two limbs deviate from the surface.

When rocks deform in a ductile way, they may bend or fold, and the resulting structures are known as folds, rather than shattering to produce faults or joints. Folds are caused by compressional or shear pressures operating over a long period of time. Such folds originate from rocks that we often consider brittle behaving ductilely when the strain rate is low and/or the temperature is high.

Geopolitics can be given as the study of the influence factors such as geography, economics, and demography on politics and especially the foreign policy of a state. Thus, the correct option is D.

Who coined the term geopolitics?

Around the turn of the 20th century, the Swedish political scientist Rudolf Kjellén first used the term "geopolitics," which expanded throughout Europe in the years between World Wars I and II (1918–39) before becoming widely used during the latter. Geopolitics is frequently used as a colloquial term for international politics in modern speech.

After World War II, geopolitical theory lost favor due to its links to imperialistic Japanese and Nazi German aggression as well as because the development of nuclear weapons and ballistic missiles diminished the importance of geographical variables in the global strategic balance of power.

The definition of geopolitics stands for the analysis of the factors including geography, economics, and demography on politics and foreign policy. Thus, option D is correct.

is water losing through transpiration harmful or benefical for plant

Answers

Answer:

Beneficial. Read below

Explanation:

Water naturally does evaporate from the leaves. When it does, it makes a sort of suction in the 'pipes' of the plant. Think of it like when you drink from a cup with a straw. You take juice out from the straw by sucking it but that makes the juice still in the cup go up to replace that lost juice. This is how plants absorb water from the roots. If transpiration didn't happen, plants wouldn't be able to absorb water apart from osmosis but that would be too slow.

An evaluation plan simply means a written document that describes how to evaluate and monitor a program.

Low air loss mattresses can be used for both the prevention and treatment of pressure wounds, and are well suited to any patients susceptible to these events such as those who are immobilized or lack adequate sensory perception.

Findings support the expanded use of this technology for patients with mild pressure ulcers and good healing characteristics. For these patients, the cost-effectiveness of low-air-loss beds is comparable to other accepted health treatments.

For patients with severe ulcers and poor healing characteristics, low-air-loss bed cost-effectiveness compares poorly with other accepted health treatments unless the lease cost can be substantially reduced, or unless life with a pressure ulcer is valued close to death.

GENES are the fundamental unit of heredity that transmit albinism from one generation to the next. Thus, the correct option is A.

What is DNA?

Deoxyribonucleic acid is a polymer made of two polynucleotide chains that coil around one another to form a double helix and which contains the genetic material necessary for all known creatures, including many viruses, to develop, function, grow, and reproduce.

Because they contain unique sets of instructions to encode certain proteins, which are passed down across generations, genes are regarded as the fundamental functional and structural components of heredity (i.e., they are inherited).

When a gene is expressed, certain DNA fragments (i.e., genes) are used as templates to produce messenger RNAs (mRNAs), which are complementary RNA sequences.

which dental material would you say is the most versatile and widely used today and why?

Answers

One of the most adaptable restorative materials in dentistry is dental amalgam. It accounts for over 75% of all restorative materials used by dentists.

What is amalgam?

Dental amalgam is a mixture of liquid mercury and metal alloys used to treat cavities caused by tooth decay in dentistry. [1] Mercury (50%) is typically found in low-copper amalgam, along with silver (22–32%), tin (14%), zinc (8%), and other trace metals.

Because of the constant expansion and contraction of amalgam fillings, they can sometimes shatter the tooth. Leakage is also less likely with composite fillings. A leaking filling indicates there is a small breach between the filling and your tooth, which allows dirt and saliva to enter and cause decay.
