According to E. Mavis Hetherington's research, Barney would most likely be categorized as a(n)

A) defeated

B) competent loner

C) enhancer

D) good-enough

The answer to this question is A) defeated

Explanation:

E. Mavis Hetherington is an important Canadian psychologist mainly known for studying divorce and the effects of it. About this, the psychologist proposed divorce is a complex process and has a great impact on those involved. In the case of the spouses, E. Mavis Hetherington proposes four main styles spouses might acquire after divorces such as competent loner, defeated, enhancer, etc.

In the category of defeated this psychologist includes those that do not cope with life after divorce, instead, they experience depression, loneliness, regrets, and other negative feelings, which stop them from thinking positively about the future or adapting to their situation. This category describes Barney because after divorce he feels regretful and depressed; also, he has great difficulty to cope with life or adapt to the situation.

Answer:

a. The formula for finding the number of colonies in a given volume is,  

CFU/ml, here CFU is the colony forming units or the number of colonies formed in a volume plated in ml × dilution

The dilution factor given in the question is 1 × 10⁻⁴ and the number of colonies given is 186. Therefore, the number of bacteria present in the given 1 ml of the milk is,  

CFU/ ml = 186 / 1 × 10⁻⁴ = 186 × 10⁴.  

Hence, the concentration of bacteria in the milk is 186 × 10⁴ CFU/ml.  

b) The limit of the bacterial concentration in the pasteurized milk is 20000 CFU/ml, however, it can be seen that the sample of the milk possess more concentration of bacteria than the desired value. Therefore, the milk is not safe to drink by Public Health Standards.  

Answer:

b. Phosphofructokinase;  Fructose-1,6-bisphosphatase

Explanation:

Glucagon is a hormone which functions to initiate gluconeogenesis whwreas insulin functions to initiate glycolysis.

Fructose-2,6-bisphosphate (F26BP) is an allosteric regulator of the glycolytic and gluconeogenic enzymes phosphofructokinase-1 (PFK-1) and fructose-1,6-bisphosphatase (FBPase-1).

It stimulates glycolysis and inhibits gluconeogenesis by binding to its allosteric site on phosphofructokinase-1 reducing its affinity for the allosteric inhibitors ATP and citrate .

It is formed by phosphorylation of fructose-6-phosphate catalyzed by  phosphofructokinase-2 and is broken down by fructose-2,6-bisphosphatase which are two separate enzymatic activities of a single, bifunctional protein (PFK-2/FBPase-2).

Phosphorylation of PFK-2/FBPase-2 due to glucagon release enhances its FBPase-2 activity thereby stimulating gluconeogenesis and inhibiting glycolysis.

Dephosphsorylation of PFK-2/FBPase-2 due to insulin release enhances its PFK-2 activity, thereby stimulating glycolysis and inhibiting gluconeogenesis.

Another factor besides distance from the sun would be "atmospheric composition".

Explanation:

Other than distance from the sun, atmospheric composition affects the temperature of a planet. Atmospheric composition is the amount of energy that gets to the exterior of a planet. The energy that gets to the exterior of a planet, affects the temperature.

Answer:

a mouthpart that can pierce fruits and seeds

Explanation:

An adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms. That being said the most likely morphological change that would trigger this would be a mouthpart that can pierce fruits and seeds. This new change would allow the beetles to consume most of the different resources that the island has to offer such as the different types of plants and fruits which were previously inaccessible to the beetles.

Answer:

The structure of the body's organs and systems

Explanation:

In medicine, a cadaver is a dead human body dissected in order to study its anatomical structure. It is employed by medical students and other medical practitioners to study the structure of the human body.

Anatomy is a branch of science that has to do with the study of the structure of living organisms. Relating anatomy to cadaver, these dead bodies are dissected in order to view and study the structure of the different compartments of the body e.g organs, systems etc.

Answer:Evaporation, condensation, precipitation, runoff

Answer:

The genera include...

Mycobacterium

Actinomyces.

Explanation:

The genera Actinomyces and mycobacterium show significant observation of gram positive bacteria because they test positive and give a violet or purple color under microscope when the undergo gram staining which is which uses crystal violet due. They are able to retain the violet color due to their posses of thick peptidoglylcan cell wall.

Actinomyces spp. Of the general actinomyces play an important role in soil ecology, and some species are human pathogens that cause diseases.

Mycobacterium genera example is bacilli which is covered with a mycolic acid coat. This waxy coat protects the bacteria from antibiotics, prevents them from destruction and hinder the penetration by Gram stain reagents. They cause different infectious diseases in humans.

Answer:

D

Explanation:

they both produce daughter haploid cells.

Mitosis and Meiosis have all of the following in common, except both results in genetically identical daughter cells. Thus, the correct option is D.

Meiosis may be defined as the type of cell division that forms four daughter cells that are haploid in nature from a parental cell. It is also known as reductional division.

The common methods of both types of cell division are both duplicate their DNA first, both result in cell division, and both have chromosomes line up in the middle of the cell.

Mitosis is only the type of cell division that results in the formation of two genetically identical daughter cells.

Therefore, the correct option for this question is D.

Contrary to popular belief, ostriches do not bury their heads in sand to avoid danger. This defensive behavior of lying low, so that they may appear from a distance to have their head buried.

Answer:

Cells can only derive from pre-existing cells.

Explanation:

The cell theory has three major postulates: 1-all organisms are composed of cells, 2-the cells are the basic unit of all living forms, and 3-the cells derive from pre-existing cells. In 2010, the J. Craig Venter Institute (JCVI) designed in the laboratory a synthetic bacterium that is able to auto replicate himself, and thereby supporting the third statement of the cell theory. This bacterium was named as Mycoplasma mycoides JCVI-syn1.0 and its creation represented a milestone in synthetic biology. M. mycoides is a bacterium that has only 473 genes coded by 531,000 bases pairs (bp), this being one of the smallest genomes of all living forms.

Answer:

B.) Oceanic crust is denser than continental crust.

Explanation:

Oceanic crust is denser, so it is subducted under the continental crust. The less dense magma then rises up through the continental crust, then it's further increasing the size of the continental crust and then maintaining it's lower density than the oceanic crust, which then causes subduction.

Answer:

Oxygen levels stay above 15 percent starting 200 million years ago

Explanation:

Atmospheric oxygen levels are related to the evolution on Earth and changes in geochemical cycles that involve climate variations.

The presence of O 2 and evolution of oxygen gave new opportunities to the life on Earth. Oxygen levels in atmosphere have fluctuated between 15% and 35% of atmospheric volume, since the start of the Cambrian period.

So, form the starting 200 million years ago, oxygen level stay above 15 percent and the correct option is "B".

This question is incomplete. Group of answer choices are:

A. G1

B. G2

C. Prophase

D. Metaphase

E. Anaphase

The correct answer is A.

Explanation:

The G1 phase (Gap 1 phase) is the period of the cell cycle from the time a cell is born until the S phase begins. When the G1 phase begins (just after the division of the stem cell) the size of the newly originated cell is half of its normal size, and the cell must grow to reach it. For this, in this period, RNA and proteins are actively synthesized. During this period, the cell has only the amount of DNA that it has received from its progenitor and each chromosome is made up of a single chromatid, since DNA replication has not yet occurred.

Answer:

1) Purines contain only four ring nitrogen atoms while Pyrimidines contain only two nitrogen ring atoms

2) Purines contain two heterocyclic rings while Pyrimidines contain one heterocyclic ring

Explanation:

Purines and Pyrimidines are two classes of nitrogenous bases that make up nucleic acids. They are both heterocyclic aromatic compounds which contains nitrogen atoms in their structure. Although, they are similar but have distinct features namely:

Purines are ring molecules which consists of four (4) nitrogen atoms in their aromatic structure. They are structures with two heterocyclic rings consisting of five (5) carbon and four (4) nitrogen atoms. Adenine and Guanine are the purines in nature.

On the other hand, Pyrimidines are another ring molecules consisting of two (2) nitrogen atoms in their aromatic structure. Their only ring i.e. 1, is also heterocyclic in nature and contains four (4) carbon and two (2) nitrogen atoms. Cytosine, Thymine and Uracil are the pyrimidines.

Answer:

All organisms are composed of cells that share a structural organization and play roles in similar biological processes.

Explanation:

All living organisms can be grouped in terms of cellular organization, functioning, and structure. These features enable us to define them as “subjects” of life. Organisms share basic biological mechanisms such as, among others, growth, homeostasis, development, energy processing, reproduction, etc. Moreover, life is also defined by the presence of essential biomolecules such as DNA, RNA, proteins and lipids. Finally, the cell is considered to be the basic unit of every life form, and organisms may be formed by one (unicellular) or more cells (multicellular). The fundamental feature of the cell is the presence of a membrane that separates it from the external environment, thereby defining its internal environment.
