A chemical reaction is an interaction that always causes:
O A. matter to be changed into energy.
B. macromolecules to be formed from glucose.
O C. molecules to break apart into atoms.
O D. atoms to be rearranged into new substances.
Answer:
D. atoms to be rearranged into new substances.
Explanation:
Chemical reactions involve interaction between chemicals such that all reactants are changed into new materials. The properties of the new materials are different from those of the reactants.
Chemical reactions involve breaking chemical bonds between reactant molecules (particles) and forming new bonds between atoms in product particles (molecules). The number of atoms before and after the chemical change is the same but the number of molecules will change.

If there are 12 chromosomes in an animal cell in the G 1 stage of the cell cycle, what is the diploid number of chromosomes for this organism?
Answer:
The gametes are haploid, having half the number of cells as compared to somatic cells. The gametes or sex cells produced by the organism will have 6 chromosomes if the organism has 12 chromosomes
Explanation:
Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable autosomal dominant genetic disease, in an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible not all offspring will receive the abnormal allele from an affected heterozygous parent.
Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease.
Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease.
Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.
Answer:
As it is given that Mark's paternal grandmother and grandfather does not carry the disease. The symbols on the right side of the Punnett represent Mark's paternal family. If both his paternal grandparents are unaffected then his father and paternal aunt are also not affected by the disease.
His maternal grandfather is affected as mentioned and also his maternal aunts are affected. Mark's mother is unaffected as she does not have the disease-causing alleles determined by genetic testing.
Both of the marks parents are unaffected which indicates that marks also do not carry the allele of the disease.
Huntington's disease is an autosomal dominant disorder in which the presence of even one dominant allele can cause the disorder.
The autosomal disorder can not skip a generation, have to be present in every generation.
Condition Given:
Affected Member: Mark's Maternal grandfather and Maternal aunts.
Normal: Mark's Maternal grandmother and Mark's Mother.
As MArk's Maternal Grandfather is affected then his genotype must be Aa because Mark's Maternal grandmother is unaffected (aa), this is the only condition where Mark's mother will be normal.
A- Dominant (Huntington)
a- Recessive
Maternal means on the mother's side and paternal means on the father's side.
The diagram is attached below.
I-1: Mark's maternal Grandmother
I-2: Mark's maternal Grandfather
I-3&4: Mark's Paternal Grandparents
II-1&2: Mark's Maternal aunts
II-5: Mark's paternal aunt
II-3&4: Mark's mother and father respectively will not have the disease as both father and mother of Mark are normal.

Which type of mutation occurs only in gametes?
germline mutation
somatic mutation
point mutation
frameshift mutation
Answer:
Germline mutation
Explanation:
A germline mutation is a genetic change produced in the gametic-germline cells (i.e., male and female gametocytes). The mutations in the germline are inherited in the next generation, while changes in somatic cells are not inherited. Moreover, the germline mutations may occur either before the fertilization or during embryonic development (zygote morula, blastula and gastrula). This type of mutation may be induced by both endogenous (e.g., oxidative DNA damage) and exogenous (e.g., exposure to UV light) factors.
The type of mutation that occurs in gametes only is : ( A ) Germline mutation
Germline mutation is a type of mutation that occurs in the gametocytes ( male and female ) and is passed( inherited ) on to the offspring ( next generation ). while mutations occurring in somatic cells are not passed on to the next generation .
Germline mutation is induced by either endogenous factors or exogenous factors and this is because Germline mutations can occur before fertilization or after fertilization.
Hence we can conclude that the type of mutation that occurs in gametes only is Germline mutation.

The graph below shows the temperature of ocean water at different depths. Which part of the graph represents the thermocline? a. AB b. BC c. CD d. DE
Answer:
C
Explanation:
Generally temperature changes rapidly with the dept in aquatic bodies especially the oceans.The thin distinct or transition layer where the variation in temperature with depth is most significant is called Thermocline.
Its represents the gaps which separate the upper mixed layer from the lower deeper water bed below,it therefore represent the layer of mixture of the upper surface warmer water (C) below 200 meters, with the cooler water layer(E) below,from 1000 meters check the attachment.
It is caused by variation in intensity of sunlight.The latter hits the surface water layer and therefore raises the temperature.But,because of decrease in sunlight penetration,with increasing dept, the temperature of the lower water dept decreases.

As Hite and Seitz (2016) discuss in Chapter 5: Climate Change, reputable scientific studies continue to show that the Earth is warming at an unsustainable rate because of a rise in the release of CO2 and methane gases. What is the relationship between population increases and climate change
Answer:
See the answer below
Explanation:
The relationship between climate change and increased population of humans is a direct one. As the population of humans increases, their activities leading to the release of greenhouse gases such as CO2 and methane also increases. The greenhouse gases are primarily responsible for the warming of the earth.
As more and more greenhouse gases are released into the atmosphere, more radiation from the sun is trapped in the atmosphere and the earth receives more warmth. This extra heat received leads to increase in the global temperature, a phenomenon known as global warming. As the average global temperature increases, climate becomes more erratic and unpredictable.
The greenhouse gases-related activities of humans that are bound to increase with the increase in population include deforestation, fossil fuel burning, industrialization, etc.

Which of the following is not a possible environmental consequence of urban sprawl?
a.
deforestation
b.
pollution
c.
loss of natural resources
d.
none of the above
The correct answer is D. None of the above
Explanation:
Urban sprawl or the expansion of human settlements such as cities has multiple negative consequences on the ecosystems. This includes deforestation because trees are usually cut to build houses and other human structures. Indeed, most threes and plants are removed for human construction. This also implies a loss of natural resources that include a wide variety of plants, animals, and even water as nearby bodies of water might be polluted. Besides, this general pollution increases in the area this includes noise pollution, water pollution and air pollution that result from human activities. Thus, all are possible consequences of urban sprawl; therefore, the correct answer is none of the above.

Answer:
In cell biology, the word Queue describes the long arm of a chromosome.
Explanation:
The long arm of a chromosome is termed the q arm. All human chromosomes have two arms; the p arm which is the short arm and the q arm which is the long arm. The two are separated from each other only by primary constriction at the center called the centromere, the point at which the chromosomes is attached to the spindle fibers during cell division.
What was the population density of the original sample? What would have happened if you had inoculated an agar plate with 1 mL of the original sample?
Answer:
The sample was at a population density of 8.75x10^4 CFU/mL originally.
Explanation:
Had it been inoculated in the way as described in the question statement, the bacterial growth would have covered all of the agar plate and we would not have been able to distinguish individual colonies of bacteria. 1 mL is too much of a sample volume to use in cases like these.

Slowing Down Global Warming As Hite and Seitz (2016) discuss in Chapter 5: Climate Change, reputable scientific studies continue to show that the Earth is warming at an unsustainable rate because of a rise in the release of CO2 and methane gases. What is the relationship between population increases and climate change
Answer:
The increasing level of all the facilities like transportation, production, human waste, and developing new spaces for human beings among others are some of the most essential features of climate change. Thus, the demand for novel products, space, and facilities would also enhance with the increase in the population. This signifies that with the enhancement in the facilities, the environment would get influenced, which would eventually influence the climate.
There would be more emission of carbon dioxide and thus more pollution would develop with the increase in the population of human beings, this further would add up in climate change and global warming. Thus, there is a need in the control of the human population, however, technology is also important in helping humans to sustain a better life. This technology should be advanced and well-equipped so that our climate and environment exhibits no deleterious effects.
Novel technologies like the use of renewable energy, green building, prudent application of resources, and others would also assist the humans in sustaining the environment.
