______ is a rock with fine dark texture that makes up the oceanic crust
Igneous is a rock with fine dark texture that makes up the oceanic crust . Ocean crust is made up of mafic magma . It erupts over the seafloor to make basalt lava flows or it may cools down to form the intrusive igneous rock gabbro . Igneous rock are further divided according to their mineral content.
When the algae in coral reefs die off due to environmental stresses, the coral subsequently dies because of lack of food. this process is referred to as ____.?
Half of the polar bears in a small population die. This population may experience changes due to _____.
This would be due to genetic drift.
Hope this helps!
Correct answer: Genetic drift
Genetic drift is defined as the process in which the allele frequency of a population is changed by chance or due to random changes in the environment. It is a random process that can lead to large changes in the overall population in a short period of time. It is a mechanism of evolution and it does produce the adaptation.
Disparities in sentencing often occur due to:
Sentencing disparities in the criminal justice system, notably those based on race, are influenced by factors including judicial discretion post-United States vs. Booker and historical policies like the War on Drugs. These disparities are evidence of both ongoing and systemic discrimination that impact sentencing outcomes.
Sentencing disparities often arise from dissimilar treatment of similarly situated individuals based on race within the criminal justice system. Factors contributing to these disparities include racial profiling, biases during pre-trial processes such as setting bail, and differences in sentencing for comparable offenses. For example, studies have shown that African Americans receive sentences approximately 19% longer than whites for similar crimes. This issue has been exacerbated by the Supreme Court ruling in United States vs. Booker, which allowed judges greater discretion in sentencing, potentially increasing the influence of their personal biases on sentencing outcomes. Moreover, policies such as the 'War on Drugs' have disproportionately affected people of color leading to higher rates of incarceration for nonviolent drug offenses. Disparities are not just a result of current practices but also historical injustices that have shaped societal structures, affecting employment, education, and poverty levels.
Unless a series of sedimentary rock layers has been overturned, which layer is usually the oldest? the layer on the top
Answer:
The correct answer is the layer on the bottom.
Explanation:
The formation of the sedimentary rock takes place by the deposition of sediments at the bottom of the water bodies like seas and oceans. The newer deposits of soil that comes via inland inlets, get settled over the previously deposited sediments. The sediments are brought in spontaneously unless and until they become sufficiently big in order to impart intense pressure on the layers underneath and thus results in the formation of rocks.
The equations summarize the process of fertilization. Which equation represents fertilization?
The equation that represents fertilization is haploid + haploid = diploid
The correct option is (c).
Fertilization is a crucial process in sexual reproduction where two haploid gametes, one from each parent, combine to form a diploid zygote. The fusion of these gametes results in the formation of a new individual with a complete set of chromosomes, one set from each parent.
In the equation "haploid + haploid = diploid," both sides of the equation represent the genetic material involved in fertilization. The term "haploid" refers to cells containing one set of chromosomes, representing either the sperm or egg cell. During fertilization, these two haploid gametes unite to form a diploid zygote, which contains two complete sets of chromosomes, one set from each parent. Therefore, the equation accurately represents the genetic process of fertilization.
Option a, "haploid + diploid = diploid," does not accurately represent fertilization because it implies that one of the gametes involved is already diploid, which is not the case in typical fertilization.
Option b, "diploid + haploid = haploid," also does not represent fertilization accurately. This equation suggests the production of a haploid offspring, which is not the result of fertilization.
Option d, "diploid + diploid = diploid," does not reflect the process of fertilization either. This equation implies the fusion of two diploid cells, which does not occur during normal fertilization.
In summary, option c, "haploid + haploid = diploid," best represents the process of fertilization, accurately depicting the fusion of two haploid gametes to form a diploid zygote, which is the fundamental event in sexual reproduction.
complete question given below:
The equations summarize the process of fertilization. Which equation represents fertilization?
a.haploid + diploid = diploid
b.diploid + haploid = haploid
c.haploid + haploid = diploid

Which of the following could be a sequence in the carbon cycle? (Hint: light enters the atmosphere… then what?)
a. plants take in carbon dioxide and produce glucose -> animals consume plants -> animals break down glucose and release carbon dioxide
b. animals break down glucose and release carbon dioxide -> animals consume plants -> plants take in carbon dioxide and produce glucose
c. animals consume plants -> plants take in carbon dioxide and produce glucose -> animals break down glucose and release carbon dioxide
d. plants take in carbon dioxide and produce glucose -> animals break down glucose and release carbon dioxide -> animals consume plants
The correct answer is option A, Plants take in carbon dioxide and produce glucose-animals consume plants-animals break down glucose and release carbon dioxide.
Reason -
The carbon cycle comprises of following stages
a) Release of carbon dioxide in the atmosphere – carbon is released in the form of CO2 as a result of exhalation process during respiration of all living species or by burning of fuels or decomposition of dead organic matter etc.
b) Carbon uptake by plants – Plants take in CO2 to produce glucose and oxygen during the process of photosynthesis.
c) Usage of carbon product produced by plants – All animals or human beings consume the plant to take in the carbon entrapped by the plant in the form of glucose
d) Release of carbon by animals/living species – Again after consuming plants, the living beings including animals exhale out CO2 by respiration, or microorganisms feed on the dead remains to release carbon in the soil
This process continues in a cyclical chain manner again and again.

In which phylum do we first see tissue–level organization? Polifera Cnidaria Nematoda
Tissue-level organization first appears in phylum Cnidaria, which includes Cnidarians with organized tissues and specialized cnidocytes, unlike the simpler phylum Porifera.
Tissue-level organization is first seen in the phylum Cnidaria. Organisms in phylum Porifera, like sponges, do not possess true tissues, but rather have a simple organization comprising different cell types that together perform necessary functions.
In contrast, Cnidarians such as jellyfish, corals, and sea anemones, have developed organized tissues from two embryonic cell layers, the ectoderm and the endoderm, and have specialized cells called cnidocytes used for stinging and capturing prey.

True or false: vitamin b12 can build up in your system and cause damage.
Vitamin B12 is not harmful. Food or high-dose supplements don't create adverse effects or high levels. Therefore, its false.
What is vitamin B12?Cobalamin, also referred to as vitamin B12, is a water-soluble vitamin essential for metabolism. Animals need it because they use it as a cofactor in the creation of DNA and in the metabolism of fatty acids and amino acids. Additionally, it plays a significant role in the growth and operation of brain and nerve cells. The protein in the foods we eat forms a bond with vitamin B12. Vitamin B12 becomes free vitamin in the stomach when enzymes and hydrochloric acid break its bond.
The amounts of vitamin B12 do not build up to hazardous levels. Whether you acquire it through food or by taking supplements at high doses, consuming a lot of it won't have any negative effects or result in high levels in your system.
