Answer:

Environmental Sciences is a multidisciplinary academic field that integrates biological, physical and information sciences for the study of the environment and solutions to environmental problems. These sciences include physics, ecology, zoology, biology, chemistry, mineralogy, oceanography, geology, soil sciences, atmosphere sciences and geography. The environmental sciences emerged from the fields of natural history and medicine. Today, they allow an integrated, quantitative and interdisciplinary approach to the study of environmental systems.

Related areas of study include environmental studies and environmental engineering. Environmental studies integrate social sciences to understand human relations, perceptions and policies regarding the environment. Environmental engineering focuses on design and technology designed to improve the quality of the environment. Environmental problems almost always include the interaction of physical, chemical and biological processes. Environmental scientists work on topics such as understanding ground processes, assessing alternative energy systems, controlling and mitigating pollution, managing natural resources and the effects of global warming, applying systemic analyzes to environmental problems.

Environmental sciences became an active field of scientific research in the 1960s and 1970s, due to the need for a multidisciplinary approach to analyzing complex environmental problems, the emergence of various environmental laws requiring specific research protocols, and increasing public awareness. the need for action to solve environmental problems.

Inability of dense irregular connective tissue to form properly will affect the formation of organs and the skin.

<h3>What is connective tissue?</h3>

Connective tissue is the tissue that provides supports, and gives structure to other tissues and organs in the body.

Connective tissue is made up of cells, elastic fibers, and collagen.

The dense irregular connective tissues are distributed throughout the body are important in the formation of the skin, the eyes and walls of organs.

Inability of dense irregular connective tissue to form properly will affect the formation of organs and the skin.

You are a botanist looking at the plant color in a new breed of Snapdragon. The two parent plants are Blue and Green and when yo

irakobra [83]

Answer:

Incomplete dominance is the inheritance pattern where the dominant allele did not mask the recessive allele completely and form a mix of both alleles. Here the inheritance is the incomplete inheritance. The ratio of F2 generation is 1:2:1.

Given:

R1R1 = 42

R2R2 = 39

R1R2 = 86

Total R1 alleles = 2*42+86 = 170

Total R2 alleles = 2*39+86 = 164

Total alleles = 334

Frequency of allele R1 = 170/334 = 0.51

Frequency of allele R2 = 164 / 334 = 0.49

Expected number of each phenotype:

Total population = 167

Blue = R1R1 = 0.51 * 0.51 * 167 = 43.44

Green = R2R2 = 0.49 * 0.49 * 167 = 40.10

Cyan = 2*R1*R2 = 2*0.51*0.49*167 = 83.46

Phenotype Observed(O) Expected (E) O-E (O-E)2 (O-E)2/E

Blue 42 43.44 -1.44 2.0736 0.0477

cyan 86 83.46 2.54 6.4516 0.0773

green 39 40.1 -1.1 1.2100 0.0302

Total 167 167 0.1552

Chi-square value = 0.155

Degrees of freedom = no. of phenotypes – 1

Df = 3-1 = 2

Critical value = 5.99

Chi-square value of 0.155 is less than the critical value of 5.99. So we accept the null hypothesis.

A fossil was found and determined by radiometric dating to be 11,400 years old. what is the ratio of carbon-14 to carbon-12 in t

LuckyWell [14K]

The answer would be 25%

Carbon 14 is radioactive material with 5700 year of half-time which will change it into carbon-12, a more stable substance. If the age of the fossil is 11,400 years old, then the amount of half-time passed would be: 11,400 years/ (5,700years/ half-time)= 2 half-time.

Since it undergo 2 half-time, the percentage should be: 100% * (1/2)^2= 25%

Why is it important to prevent thermometer from resting no the bottom of the test tube?

Mariana [72]

Answer:

It's important to not touch the sides or the bottom of the test tube with the thermometer because touching it to the sides or bottom of the test tube fractures the glass and does not allow for correct temperature measurements.
