Answer:
Earth is comprised of four circles: the lithosphere, hydrosphere, atmosphere, and biosphere. Changes in any piece of the Earth's framework influences every single other circle.
For example, storms structure in the air which bring precipitation and leads to the rain. Rain influences the hydrosphere by expanding the measure of water in a river, which influence the progression or flow of the stream. flowing rivers change the outside of the lithosphere. Plants and creatures in the biosphere rely upon water to endure.
The Law of Overcompensation and Overload allows for which of the following in regards to intensity?
A. Progressively increase over a period to time
B. Progressively decrease over a period of time
C. Remain the same
D. Acute decrease over a period of time
Answer:
A. Progressively increase over a period to time
Explanation:
The law of overcompensation states that the environment compensates for any factor by twice the amount and the overload theory states that challenges should be increased while working on a certain task to improve the results.
The laws allow for the following:
Option A. Progressively increase over some time.
The laws can be explained as:
In fitness and sports, the laws of overload and overcompensation are widely used. The overload principle says that the intensity and exercise duration should be increased gradually to see an improvement in endurance, strength and muscles.According to the overcompensation theory, the body recovers from any injury or harm the body does not quit there and will be stronger compared to before.Thus, overcompensation and overload increase over time.

what is a part of interphase A. cytokinesis B. telophase C. anaphase D. s phase
Answer:
D
Explanation:
I did it on my own soci know it's the answer
In the context of interphase, the S phase is the specific part where DNA replication occurs, contributing to the overall process of cell division and ensuring the transmission of genetic material to new cells and the correct option is option D.
Interphase is the longest phase of the cell cycle, and it is divided into three main stages: G1 phase, S phase, and G2 phase. Among these stages, the S phase is specifically responsible for DNA replication. It is during the S phase that the cell's DNA is duplicated in order to prepare for cell division.
During the S phase, the DNA helix unwinds, and the two strands separate. Enzymes and proteins then work together to synthesize new complementary strands for each of the separated DNA strands. As a result, two identical copies of the DNA molecule are produced.
The S phase plays a crucial role in maintaining the genetic integrity of the cell. By accurately duplicating the DNA, the cell ensures that each daughter cell formed during cell division receives an identical set of genetic information. This is vital for the proper functioning and development of organisms.
Thus, the ideal selection is option D.

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.

Implanting an electrode that supplies a weak electrical current to specific brain areas is called _____. It is useful in the treatment of _____
Answer:
Deep Brain Stimulation (DBS)
Depression, Uncoordinated body movements such as in Parkinson's disease
Explanation:
Deep brain stimulation is a surgical procedure in which a device that sends electrical impulses to the brain by means of lead wires connected to electrodes placed in the specific areas of the brain, is implanted in the body, typically the chest region.
This surgical procedure is usually required to treat diseases in which there is irregular and improper nervous stimulation of the brain resulting in various nervous disorders such as irregular muscle movements as in Parkinson's disease as well as depression.
The impulses sent from the stimulator device to the electrodes in the brain through the wires, serves to stabilize and normalize nerve signals sent to the brain.
A circular double-stranded DNA molecule contains 4200 base pairs. In solution, DNA is in a B-form helix, with about 10.5 base pairs/turn. The DNA has 12 superhelical turns. What is its superhelix density
Answer:
The correct answer is - 3 × 10⁻²
Explanation:
first find LKo = length of BDNA/ 10.5 bp/turn
= 4200/10.5
= 400
now calculate Δ LK= LK - LKo
ΔLK = 412-400
ΔLK = 12
now, superhelix density = ΔLK/LKo
⇒ 12/400 = 0.03
= 3×10⁻²
Thus, the correct answer is - 3 × 10⁻²

. Some people have developed allergies to animal insulin. Explain why the immune system would be able to distinguish animal insulin from human insulin
Answer: Difference between animal and human insulin and/or not being properly purified.
Explanation:
Insulin is a hormone that regulates the metabolism of secreted by the β-islet of Langerhans cells of the pancreas. It that allows blood sugar, known as glucose, to pass into cells. Glucose comes from the food and drinks and it is the body's main source of energy. So, insulin plays a key role in maintaining proper blood glucose levels.
Animal insulin is produced by the pancreas of animals, usually cows and pigs. Then, the insulin is purified to reduce the chance of the insulin user developing a reaction to the insulin.
Each organism has its own genetical identity and any foreign particle is treated as an antigen. And, there is small chemical difference between insulin produced in animals and insulin produced in humans. That difference, caused by a different sequence of peptides, can be recognized by the immune system as something foreign and as such can be a threat to the body. And that would trigger an immune response. Also, the response can be because it hasn't been properly purified and contains other compounds or proteins that are also foreign.

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.

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:
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.

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.
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.
