Apply concepts of processes of the carbon and water cycle
and hypothesize how the mercury is added to the water supply
and how it affects marine organisms.
Answers
Answer:
Carbon is a chemical element vital to all living things and is present in many non-living things. Carbon circulates around the planet in what is called the carbon cycle. Parts of the cycle store carbon for different lengths of time, and there are many processes that move carbon in and out of the stores. Carbon moves through the carbon cycle in stops and starts. An individual atom might pass through plants, animals and the atmosphere in a matter of days, yet stay trapped in rocks for millions of years. Plants exchange carbon with the atmosphere every day as they make and use carbohydrates for energy, but plants also store carbon because they use it to build their structures – some trees store carbon for hundreds of years. This carbon only moves on again if the tree dies and decays or is burnt. Carbon can be stored for much longer periods too – for thousands of years in the ocean or for millions of years in rocks.

''A polygenic trait that follows non-Mendelian inheritance patterns'', is the statement best describes human eye color.
What is meant by non Mendelian inheritance?Any pattern in which characteristics do not segregate in line with Mendel's rules is referred to as non-Mendelian inheritance. These principles describe how qualities connected to a single gene on nuclear chromosomes are passed down across the generations. Each parent contributes one of the two potential alleles for a characteristic in the Mendelian system of inheritance. The distribution of phenotypes anticipated for a population of children may be calculated using Mendel's laws if the genotypes of both parents in a genetic cross are known. The proportions of phenotypes observed in the progeny occasionally do not match the values expected.Many diseases that affect the processes are impacted by non-Mendelian inheritance.Learn more about non Mendelian inheritance refer to :

predict the effects of a pancreatic tumor that secretes insulin. how would the effects change if the tumor secreted glucagon instead?
Answers
Extreme hypoglycemia would result from an insulin secreting tumour because the extra insulin would cause glucose to be taken up, stored, and eliminated from the circulation.
A tumour that secretes glucagon would result in hyperglycemia because of excessive glucose synthesis and release. Tumors in the pancreas are known as insulinomas. They produce more insulin than your body can utilise. Low blood sugar, or hypoglycemia, can be brought on by insulinomas. Confusion, perspiration, weakness, and a quick heartbeat can all be symptoms of low blood sugar. Your pancreas produces the hormone glucagon to aid in controlling your blood glucose (sugar) levels. A different hormone, insulin, lowers blood sugar levels, whereas glucagon raises it and keeps it from falling too low.

Which is a non-Mendelian trait?
A. A trait controlled by many genes
B. A trait with a clearly dominant form
C. A trait controlled by one gene
D. A trait with two alleles
Answers
Answer:
The answer would be A.
Explanation:
Non-Mendelian traits are traits that are not passed down with dominant and recessive alleles from one gene. Examples of polygenic traits are hair color and height. ... Other traits, such as blood type, show codominance, where there is no dominant or recessive allele.
A non-Mendelian trait would be a trait that is controlled by many genes. The right option would be A.
Mendelian traits are traits that obey the principles of the Mendelian laws While non-Mendelian traits simply do not conform with the principles and laws of Mendel.
A trait that is Mendelian would have the following:
Show simple dominance or recessive formControlled by a single geneEach gene must have 2 alleles. The 2 alleles can be the same (homzygous) or different (heterozygous).Thus, a trait that is controlled by many genes is clearly a non-Mendelian trait.

Perforating canal
Central canal
Canaliculus
Llamella
Answers
The cylindrical channel that lies in the center of the osteon is the central canal. This canal is surrounded by concentric layers of bone matrix called lamellae, and the canaliculi extend from the central canal to allow for the exchange of nutrients and waste products.
Perforating canals, on the other hand, are channels that run perpendicular to the central canals and connect them to the periosteum and medullary cavity. I hope this explanation helps!
- Perforating canals are channels that connect adjacent osteons and provide a pathway for blood vessels and nerves.
- Lamella refers to the concentric layers of bone matrix that surround the central canal in an osteon.
- Canaliculi are tiny channels that connect lacunae, allowing for communication between bone cells and nutrient exchange.
the Central canal is the correct term for the cylindrical channel in the center of the osteon, while the other terms mentioned (Perforating canal, Canaliculus, and Lamella) are also important components of the bone's structure and function.

Answer:
Question 13:
B. False
The most abundant photoreceptors that detect dim light are Rods, not Cones. Rods are highly sensitive to low light conditions and are responsible for vision in dim light and peripheral vision. Cones, on the other hand, are responsible for color vision and high visual acuity but are less sensitive to low light conditions.

the helicase aquarius/emb-4 is required to overcome intronic barriers to allow nuclear rnai pathways to heritably silence transcription
Answers
The helicase Aquarius/EMB-4 is an essential factor in overcoming intronic barriers to enable the nuclear RNAi (RNA interference) pathways for the heritable silencing of transcription.
The helicase Aquarius/EMB-4 plays a crucial role in RNAi, a biological process that regulates gene expression. In eukaryotic cells, DNA is transcribed into RNA molecules, which are then translated into proteins. However, certain RNA molecules can also have regulatory functions, such as RNAi.
Intronic barriers refer to the presence of introns, non-coding regions within genes that are transcribed but not translated. These introns can act as obstacles for the nuclear RNAi pathways, preventing the proper regulation of gene expression.
Aquarius/EMB-4 is responsible for unwinding the RNA molecules in these intronic regions, facilitating their processing and enabling the nuclear RNAi pathways to silence transcription effectively. By doing so, it allows for the inheritance of the silenced state in subsequent generations.
In summary, Aquarius/EMB-4 helicase is necessary to overcome intronic barriers, enabling the nuclear RNAi pathways to heritably silence transcription.

Conversion of fivcogen to glucose in muscle cells Alexkown of trigheendes into glycerol phosphate and fatty ackis in adipocyras Oxidation of lipid by liver cehs Synthesis of protein by muscle cells Oxidation of glucose by muscle cells
Answers
The processes that would occur at higher rates in the fed (absorptive) state than in the fasted (postabsorptive) state are:
- Conversion of glycogen to glucose in muscle cells
- Synthesis of protein by muscle cells
- Oxidation of glucose by muscle cells
The conversion of glycogen to glucose in muscle cells occurs during the absorptive state as glucose is taken up from the bloodstream and stored as glycogen in the muscle cells. In the postabsorptive state, glycogen is broken down into glucose to maintain blood glucose levels.
Synthesis of protein by muscle cells also occurs during the absorptive state when there are high levels of amino acids available from dietary protein. In the postabsorptive state, protein breakdown may occur to provide amino acids for energy.
Oxidation of glucose by muscle cells is also higher during the absorptive state as glucose is readily available from the diet. In the postabsorptive state, glucose levels may be lower, and alternative fuel sources like fatty acids may be used for energy instead.
The other processes mentioned, conversion of triglycerides into glycerol phosphate and fatty acids in adipocytes, and oxidation of lipids by liver cells, are more likely to occur during the postabsorptive state when stored energy sources like fat are used for fuel.

Several factors are driving the growth of wind power, including government incentives, technological advancements, and increasing public awareness of the need for renewable energy sources. As these factors continue to support the growth of wind power, it is likely that the trend of increasing wind power generation will continue into the future.
Of course, there may be other factors that could affect the growth of wind power, such as changes in government policy or the availability of other energy sources. However, based on the current trend, it is reasonable to predict that the use of wind power in the United States will continue to increase in the next five years.

During which phase of mitosis do the sister chromatids move apart?.
Answers
Answer:
anaphase
Explanation:
Read each of the sentences that describe a phase of meiosis. Place each sentence into the correct box.
Answers
Answer:
Prophase1-crossing over may occur between the non-sister chromatids
Metaphase1- Homologous chromosomes line up at the center of the cell
Anaphase and telophase 1- homologous pairs separate and move towards opposite ends of the cell, Nuclear membrane forms and cytokinesis follows.
Meiosis 2- haploid number of duplicated chromosome line up…
Sister chromatids separate and become daughter…
Four haploid daughter cells are formed….
Explanation:
Meiosis I
P-I: Chromosomes condense, nuclear membrane dissolves, homologous chromosomes form bivalents, crossing over occurs
M-I: Spindle fibres from opposing centrosomes connect to bivalents (at centromeres) and align them along the middle of the cell
A-I: Spindle fibres contract and split the bivalent, homologous chromosomes move to opposite poles of the cell
T-I: Chromosomes decondense, nuclear membrane may reform, cell divides (cytokinesis) to form two haploid daughter cells
Meiosis II
The second division separates sister chromatids (these chromatids may not be identical due to crossing over in prophase I)
P-II: Chromosomes condense, nuclear membrane dissolves, centrosomes move to opposite poles (perpendicular to before)
M-II: Spindle fibres from opposing centrosomes attach to chromosomes (at centromere) and align them along the cell equator
A-II: Spindle fibres contract and separate the sister chromatids, chromatids (now called chromosomes) move to opposite poles
T-II: Chromosomes decondense, nuclear membrane reforms, cells divide (cytokinesis) to form four haploid daughter cells
The final outcome of meiosis is the production of four haploid daughter cells
