Answer:
D. contact metamorphism
Explanation:
When there's a volcanic activity in certain area, very often it happens that there's magma that intrudes into the cold rock in the surrounding area. The intrusion of the hot magma into the cold rock layers causes big changes into the structure of the rocks. The high temperature and high pressure manage to influence the structure of the preexisting rocks, mostly on the places where the magma touches the cold rocks, leading to the formation of metamorphic rocks. This type of metamorphism is known as contact metamorphism.

What is a sporophyte?
Answer:
A sporophyte is the diploid multicellular stage in the life cycle of a plant or alga. It develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent.
Final answer:
The sporophyte is the diploid stage of the plant life cycle that produces haploid spores through meiosis, which then grows into the gametophyte generation. This stage is more prominent in vascular and seed plants compared to non-vascular plants.
Explanation:
A sporophyte is the multicellular, diploid phase of the plant life cycle which is involved in the process of alternation of generations. To clarify, plants alternate between two main stages: the gametophyte (haploid) stage and the sporophyte (diploid) stage. The sporophyte arises from the fertilized gamete and is characterized by having two sets of chromosomes, one from each parent. This stage of the plant produces spores by a process called meiosis, wherein the chromosome number is halved, leading to the formation of haploid spores. These spores then grow, by mitosis, into a new gametophyte (haploid) generation.

Final answer:
Option B correctly describes a step in cellular respiration, where carbon dioxide and water are produced and energy is transferred to ATP. This is part of a multistep process that includes glycolysis, oxidation of pyruvate, the Krebs cycle, and the electron transport chain.
Explanation:
The correct description that properly describes a step involved in cellular respiration is option B. Carbon dioxide and water are released after the energy molecule is charged. In the process of cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and during this process, the energy previously stored in glucose is transferred to ATP (adenosine triphosphate). ATP is the molecule that cells use to perform work, such as contracting muscles.
Cellular respiration can be broken down into several key stages:
Oxidation of pyruvate to Acetyl CoA.
The Krebs cycle, which takes place in the mitochondria and fully oxidizes Acetyl CoA into carbon dioxide.
Electrons from food are moved down the electron transport chain in the mitochondria's inner membrane, leading to the phosphorylation of AMP to produce ATP.
Thus, glucose plus oxygen yield carbon dioxide and water, and the energy released during this reaction is captured in the form of ATP, which is used by the cell.
what is the path of carbon dioxide out of the body
Answer:
The oxygen circulates in your body, gets used up, and carbon dioxide is the result. The carbon dioxide then travels with your blood back to your lungs and is diffused to the alveoli, where it is exhaled.

Which is a function of the hormones secreted by the pancreas?
a they regulate blood levels of glucose.
b They maintain water and salt balance.
c They stimulate the pituitary gland.
d They regulate blood levels of calcium.
Answer: The answer is A. They regulate blood levels of glucose.
Explanation:
Pancreas: insulin- reduces blood-glucose levels; glucagon- increases blood-glucose levels
Answer:
The correct answer is letter A. They regulate blood levels of glucose
Explanation:
Pancreas secrete a kind of hormony called insulin. This sort of hormony regulates the levels of glucose in the whole body. It is important for us. When we have a problem inside pancreas and this organ can't secrete the insulin anymore, a disease appears in our body called diabetes. The levels of glucose in our body starts to increase and people that have this kind of disease need to take insulin injection.
how to count volume
The SEC dictates how volume is counted. Thus, volume is counted in the same manner on all markets based on the above reporting structure. Any time money changes hands (or any time capital is risked), it must be counted as a trade. Examples: 1) One registered market participant on Nasdaq buys 100 shares into inventory from another registered market participant or from one of its clients. In either case, it is counted as 100 shares. 2) One member firm on the NYSE or Amex buys 100 shares from another member firm. The Specialist matches the order between the two firms and it is counted as 100 shares. 3)The Specialist sells 100 shares from his inventory to a member firm on the NYSE. It is counted as 100 shares. 4) A Market Maker receives an order to buy 100 shares from it's client. It does not have 100 shares in its inventory. It must go buy 100 shares from someone else. It then sells these 100 shares to the client. Thus, there are two trades in this example for a total of 200 shares.

What are examples this kind of pollution may cause?
A acid rain, which may cause diseases such as asthma
B global warming, which may cause diseases such as skin cancer
C respiratory diseases such as emphysema
D artificial eutrophication, harming aquatic animals
The correct answer related to the examples of pollution caused by this activity is D. Artificial eutrophication, harming aquatic animals
The picture shows a person applying inorganic fertilizer to a field, which is a common human activity related to agriculture. This activity can lead to environmental pollution, particularly in the form of nutrient pollution.
Artificial eutrophication occurs when excess nutrients, often from fertilizers, enter water bodies such as rivers, lakes, and ponds. These nutrients, primarily nitrogen and phosphorus, can cause an overgrowth of algae and other aquatic plants, leading to water quality issues and harm to aquatic animals.
This process can deplete oxygen levels in the water, leading to fish kills and other negative impacts on aquatic ecosystems.
Suppose you have made the following hypothesis:
The greater the height from which you drop a ball, the faster the ball will be traveling when it hits the ground because gravity has more time to speed it up.
If you observed that two identical balls, dropped from the same height, each reached the ground with a speed of 3 m/s, does that evidence support the hypothesis?
A. Yes, the evidence supports the hypothesis.
B. No, the evidence contradicts the hypothesis.
C. The evidence is not related to the hypothesis.
Answer:
maybe c
Explanation:
I hope this helps
Answer:
The correct answer is option C. the evidence is not related to the hypothesis.
Explanation:
The given experiment is not related to the hypothesis as the hypothesis is that with the increase in the height the speed of traveling of ball increases due to gravity. According to the hypothesis the gravity has more time to speed the ball.
The given experiment has no independent variable that can explain or test the effect of gravity on the balls because both balls dropped from the same height.
Thus, the correct answer is option C. the evidence is not related to the hypothesis.
*blank* harvesters have replaced hand labor in many agricultural fields
do we have options? can't help without options.
Mechanical harvesters have increasingly replaced human labor in agriculture due to factors like labor shortages and the drive to reduce costs and increase efficiency. This is part of a larger trend in mechanization driven by technological advancements and environmental considerations, as machinery becomes more capable of performing complex tasks and reducing waste.
Mechanical harvesters have replaced hand labor in many agricultural fields, signaling a major shift in how agriculture is approached. The introduction of mechanization in farming practices has allowed for significant advancements in productivity and efficiency. In regions like California, farmers are investing in sophisticated machinery capable of handling even delicate tasks such as fruit harvesting that were previously done by hand. This transition is driven by various factors, including labor shortages caused by changes in migration patterns and economic conditions, as well as the inherent capitalist motivation to reduce costs and improve profits.
The evolution of agriculture has often been in step with technological advancements. Large-scale, efficient farm machinery like tractors, cultivators, and combine harvesters have replaced many manual farming activities, drastically reducing the number of people required to operate a farm. Over time, the need for human labor on farms has decreased, particularly in high-income countries such as the United States. However, as labor costs rise, so does the incentive to automate, which underscores the capitalist drive to innovate and maximize profit margins.
In addition to labor-saving motivations, environmental concerns also play a role in agricultural mechanization. The use of fossil fuels has led to an increase in greenhouse gas emissions, and there is a growing focus on renewable energy sources and more efficient use of biomass. The farm equipment manufacturing industry has evolved accordingly, producing machines that not only harvest crops but also manage post-harvest handling, aiming to exploit every part of the crop and minimize waste.

Extinction is the term used for the termination of any organism or of a group of organisms which are commonly called as species.
Death of organisms or a species results in their extinction. Out of all over five billion species that have ever existed on the earth, about 99 percent have already gone extinct.
While the current number of species that exist on earth have reduced to a range of 10 million to 12 million.
In January, a small number of eastern cottontail rabbits were introduced into Red Forest. The population curve of the rabbits is shown below.
According the information shown in the graph, what is the carrying capacity for eastern cottontail rabbits in Red Forest?
A. 75
B. 100
C. 125
D. 15
Answer:
B: 100
Explanation:
Carrying capacity is the point where a population stops growing and stays stable.
Answer:
B:100
Explanation:
Carrying capacity refers to the maximum number of members of a population that a particular environment can sustain for survival. In any ecosystem, the basic resources that organisms need for survival are always in limited supply. Examples include food, water, sunlight, oxygen, and shelter.
As a growing population reaches the limits of the available resources in an environment, its size levels off to "match" the amount of resources available. In doing so, the population reaches its carrying capacity.
In this example, the population of eastern cottontail rabbits levels off at around 100 individuals.
your lab receives some new samples of CHNOPS saliva. one of the genes has 30 DNA nucleotides in it. how many amino acid monomers will be present in the completed polypeptide.
HELPPP!!!
Each codon is made up of 3 nucleotides and all codons except the end codons code for one amino acid.
So 30/3=10 codons which code for a peptide with 9 amino acid monomers.
Hope this helps:))
Final answer:
A gene with 30 DNA nucleotides will code for a polypeptide containing 10 amino acids, assuming all nucleotides are part of codons that result in amino acids and do not include a stop codon.
Explanation:
To determine how many amino acid monomers will be present in the completed polypeptide from a gene with 30 DNA nucleotides, one must consider the genetic code. The genetic code is a set of rules used by living cells to translate information encoded within genetic material (DNA or mRNA sequences) into proteins. It is established that a sequence of three nucleotides, known as a codon, codes for a single amino acid.
Based on the information in the question:
Firstly, divide the total number of DNA nucleotides by three to get the number of codons (30 DNA nucleotides / 3 nucleotides per codon).
This equals 10 codons in the gene sequence.
As each codon translates to one amino acid, there will be 10 amino acids in the completed polypeptide chain.
Note that this calculation assumes the absence of a stop codon within these 30 nucleotides, as a stop codon would terminate translation early.

Which of these best completes the statement about the interaction of the respiratory system with the circulatory system? The lungs add - whaaaaaa? T^T
I don't see options to complete the sentence, so I will try my best to explain.
Respiration is the process of gas exchange between the lungs and the environment. The lungs pick up O2 from the environment during inspiration, and expel CO2 during expiration.
External Respiration is the gas exchange between the lungs and the blood.
- In the alveoli of the lungs, blood flows past during pulmonary circulation and through the process of diffusion, CO2 from the blood enters the alveoli and O2 from the alveoli enters the deoxygenated blood.
Internal Respiration is the gas exchange between the blood and the cells of the body.
- After picking up the O2 from the alveoli in the lungs, the newly oxygenated blood flows around the body and, through diffusion, sends the O2 to the body cells, and picks up the CO2, thus becoming deoxygenated.
Why do we need Oxygen to survive???
- Oxygen serves as the final electron acceptor in the electron transport chain of cellular respiration!

After chlorofluorocarbons were banned, which class of chemicals was used in their place?
Answer:
The correct answer would be fluorinated compounds and HFCs.
Explanation:
Chlorofluorocarbons or CFCs are halocarbons that contain molecules of chlorine, fluorine, and carbon. These chemicals were heavily used in sprays, packaging materials and refrigerators. CFCs cause depletion in stratospheric ozone.
Due of their harmful effects on ozone layer, chlorofluorocarbons have been banned since 1996. After the banning of chlorofluorocarbons, hydroflurocarbons (HFCs) and fluorinated compounds are in used in place of CFCs as they do not deplete stratospheric ozone as much CFCs does, and do not contain chlorine.
Thus, the correct answer would be fluorinated compounds.
Chlorofluorocarbons (CFCs) were replaced by hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) after they were banned due to their harmful effects on the ozone layer. These replacements are still used in aerosols and refrigerants but are less damaging to the ozone.
Explanation:After the ban on chlorofluorocarbons (CFCs) due to their damaging effects on the stratospheric ozone layer, hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) have been widely adopted as replacements. These chemicals were still used as aerosol propellants and refrigerants, like CFCs, but were designed to be less harmful to the ozone layer. HCFCs and HFCs, although better for the ozone layer, still hold global warming potential and contribute to the broader issue of climate change. Consequently, there is ongoing research and development to find alternative chemicals that have minimal environmental impacts.
