Answer:
Contact -- Close to a hot spot
Regional -- At deep subduction areas.
Dynamic -- Along a transform boundary
Impact -- Near a crater
Explanation:
Contact metamorphism occurs close to the igneous intrusions and is resultant wot a high temperature and only a small surrounding area is heated by the magma and is restricted to zones surrounding the intrusion. The regional metamorphism is large scale metamorphism and is due to the convergence of the continental crust along the tectonic margins. The dynamic metamorphism are associated with the zones of moderate stains fault zones. The impact of metamerism is a result of the heat and high pressure and this can lead to the high pressure within rocks.Which describes an atom that has fewer neutrons than protons and more electrons than protons? negative compound positive compound positive ion negative ion
Answer:
Negatively charged ion
Explanation:
Negatively charged ions are called anions and they have more electron than than protons and more protons than nuetrons.
When an atom has fewer neutrons than protons and more electrons than protons, such an atom is said to be an anion. Hence, it is negative ion.
Depending on the number of proton and electron, there are 3 types of atoms:
Neutral atoms in which the proton and electron numbers are balancedCation in which the proton number is more than the electron numberAnion in which the electron number is more than the proton numberIn this case, the atom has more electrons than protons and, therefore, is an anion. The excessive electron makes such atom to be negatively charge.
Therefore, an atom that has fewer neutrons than protons and more electrons than protons is a negative ion.

What evidence is there that the endangered species act is causing harm to species????
Answer:
There is strong and increasing evidence the Endangered Species Act is causing widespread harm to the species it is supposed to protect-to the extent the Act may be doing more harm than good. The Act makes otherwise normal and legal forms of land and resource use illegal, such as farming, home building and cutting timber. The Endangered Species Act’s severe penalties-$100,000 and/or 1 year in jail for harming a single species or even unoccupied habitat that is deemed suitable-turn species in to liabilities. As a result, landowners seek to reduce their liabilities in a number of ways.

Hiking in the snowy woods, you peek inside a cave and encounter a hibernating grizzly bear! Its metabolic rate seems to be very low. What do you predict is the predominant type of reaction occurring in this bear?
Answer and Explanation:
Dormancy is a period in an organism´s biological cycle in which its growth, development, and physic activity gets suspended for a period of time. This causes a drastic reduction in metabolic activity, allowing the organism to conserve its energy. Dormancy is closely related to environmental conditions, and it is considered to be an adaptation mechanism by which organisms respond to extreme conditions.
Hibernation belongs to this dormancy process, in which animals progressively decrease their metabolic rates and their body temperature is held a few degrees over the ambient temperature. During hibernation, all functions are reduced: cardiac rime, respiration, renal function, and etcetera.
Before hibernating, bears eat a huge amount of food because this energy is what will keep them alive while hibernating. This action is known as hyperphagia, and while doing it, bears accumulate fate in their tissues. As these animals need to maintain the energy balance and metabolic health, they make use of these reserves. The nutrients excess will turn into triglycerides, that the animal will use to store in the fatty cells. There are several elements involved in the process, such as sugar, amino acids, glycerol, among others.
The fatty acid catabolism is the predominant reaction that occurring in this bear. Option C is correct.
Hibernation:
In this condition, animals decrease their metabolic rates and their body temperature is increased a few degrees over the ambient temperature. During hibernation, the heart rate, respiration and renal function is reduced.
The bears hibernate in the winter because of the lake of food outside. Hibernation help them to stay alive even in the no food is available for few months.
Before hibernation, bears eat a huge amount of food and store a lot of fat this fat provide a constant supply of energy during hibernation.
Therefore, the fatty acid catabolism, provide the energy during hibernation of bears.

Classification of organisms into three domains is based on:
A) the presence of a cell wall
B) the number of cells in the organism
C) cellular organization
D) nutritional requirements
Answer:
C
Explanation:
cellular organization is the components that make up the cell and how they are arranged inside it. Each component, called an organelle, performs a specific function that is vital for the cell.
The Bacteria, Archaea, and Eukarya are the three domains of the classification. The cellular basis of the classification of the three domains. Thus, option C is correct.
What is the cellular organization?The cellular organization is the arrangement of the cells that are the smallest unit of the organism. The cells of the body make groups at the hierarchical level and perform a specific function.
The domains are not classified based on the cell wall as the animal and plant cells are grouped in the eukarya together. They are also not organized based on the number of cells as bacteria and Archaea both are single-celled.
The domains are not classified based on the nutritional requirements as the modes of nutrition varies in the eukarya domain itself and not just the two other domains.
Therefore, option C. cellular organization is the basis of domain classification

Which of the following factors might cause checkpoint genes to interrupt cell division? Check all that apply. Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.
Answer:
Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.
Explanation:
All the three options given can cause checkpoint genes to interrupt cell division.
Checkpoint genes are transcription genes that control cell cycle and sense defects during cells processes like DNA replication, segregation e.t.c and create response till the defects is repaired in the DNA. The important of checkpoint is that it ensure enough nutrients are available to support for division, ensure that the DNA has not been damaged, ensure that cells DNA is copied correctly and make sure cells have enough RNA for their protein synthesis.
Checkpoints genes can interrupt cell division if the dna is damaged, Dna is copied incorrectly and neurological signal sent from fear responses in an organisms tell the cells to stop.
Answer:
The cells DNA has been damaged somehow and The cells DNA was replicated incorrectly
Explanation:
sometimes, these checkpoint genes are mutated or damaged and, thus, are unable to tell a damaged cell to stop dividing. When this occurs, the damaged cell gives rise to many damaged cells, which in turn create more damaged cells. These dividing cells form a NEOPLASM

Explain the concept of functional specialisation and describe two brain areas that exhibit functional specificity
Answer:
Functional specialisation explains how the two cerebral hemispheres are specialized in different types of mental activity.
Explanation:
The nervous systems of all animals have in common a number of basic functions, the most notable of which are control of movement and analysis of sensation. What sets the human brain apart is the variety of more specialized activities it is capable of learning and the integration and control of the different functions. In 90% of the population the left cerebral hemisphere specializes or controls the ability to speak and write, and the ability to understand spoken and written language. In the remaining 10%, the right hemisphere or both hemispheres dominate spoken or written language. The right cerebral hemisphere perceives tactile stimuli and spatial vision relationships better than the left hemisphere. Another area, the posterior-parietal lobe is related to the tactile abilities, it is particularly involved in the abilities to name and point out the parts of the body, one's own and of others, as well as in the abilities to name, distinguish, recognize or draw the fingers of the hand. The parietal lobe is particularly involved in perceptual accuracy in locating stimuli, in estimating line orientation (parietal-frontal lobe) and in the ability to estimate the number of stimuli presented in the central visual field.

7. Suppose you were culturing a population of bacteria at 15 degrees Celsius and then raised the temperature of the culture to 37 degrees Celsius. What effect do you think this might have on the fatty acid composition of the membrane? On the transition temperature of the lipid bilayer? On the activity of membrane desaturases?
Answer:
See below
Explanation:
An increase in the temperature will result in greater fluidity of the lipid bilayer membrane, since the unsaturated fatty acids are increased. The membrane tends to be stiff at lower/colder temperatures.The transition temperature refers to the temperature at which the membrane goes from solid to liquid state, which will be raised in this case. This is due to the increase in saturation of fatty acids.The activity of the enzymes membrane desaturases will decrease under these conditions.An unfertilized egg cell has six chromosomes. After fertilization, how many chromosomes should the zygote have?
Answer:
12 chromosomes, because the basic (haploid) number of chromosomes is 6 (n: 6)
Explanation:
The unfertilized egg contains a basic (haploid) number of chromosomes (n), being in this case 6. In humans, for example, the gamete haploid cells have a basic n content of 23 chromosomes, while in somatic cells this DNA amount is duplicated (2n), being therefore 46 chromosomes that are organized into 22 pairs of autosomal chromosomes and two sex chromosomes (X and Y).
In many popular fictional movies and books, future projections of the earth (and other fictional planets) show a world devoid of plants, with civilization bustling with activity throughout a worldwide city of skyscrapers hundreds of stories high. Based on your reading about photosynthesis and cellular respiration (Chapters 9 & 10), is this future world possible? Explain why it is or is not possible in terms of energy flow in the biosphere.
Explanation:
Cellular respiration and photosynthesis are two important physiological processes which formed the basis of life on Earth.
Evolutionary studies have shown that process of photosynthesis evolved earlier in organisms which led to the production of oxygen. This led to the formation of aerobic cellular respiration in organisms.
In the given, a world devoid of the plant is not possible because the plants perform the role of primary producers that is they utilize the available carbon dioxide and water and form the first stable energy molecule called glucose.
This glucose is broken down by the process of cellular respiration to further usable form. These two processes maintain the flow of energy on Earth.
Thus, without these two processes, the fictional world will not be possible.
