Which of the following describes how Earth’s temperature is maintained by the greenhouse effect?A, Gases such as carbon dioxide and methane reflect heat from the Earth back towards Earth’s surface.B. Gases such as carbon dioxide and methane reflect heat from the sun, preventing it from reaching Earth’s surface.C. Gases such as oxygen and nitrogen reflect heat from the Earth back towards Earth’s surface.D, Gases such as oxygen and nitrogen reflect heat from the sun, preventing it from reaching Earth’s surface.
Answers
The greenhouse effect refers to the fact that the atmosphere helps to maintain the temperature on Earth by preventing the heat from the sunlight to escape into space.
Greenhouse gases are the ones that are capable of preventing the sun's heat from escaping, such as:
• carbon dioxide
,• methane
,• ozone
,• water vapor
The greenhouse effect is not a harmful process just by itself, in fact, it allows the existence of life on Earth, but the human activity adds greenhouse gases to the atmosphere, causing more heat to be retained.
This means the right answer is A, Gases such as carbon dioxide and methane reflect heat from the Earth back towards Earth’s surface.

The four levels of protein structure are primary, secondary, tertiary, and quaternary structure. Review the levels of protein structure by clicking the image below.
Drag each label into the appropriate bin depending on whether it applies to primary, secondary, tertiary, or quaternary structure.
Answers
Proteins are composed of a sequence of amino acids linearly arranged. To accomplish their functions thet must adopt different structures. Primary structure: Amino acid sequence. Secondary structure: Alpha helix. Beta pleated sheet. Results from hydrogen bonding between the backbone constitutents of the polypeptide. Tertiary structure: Results from interaction between side chains (R groups) of amino acids. The overall shape of the polypeptide. Quaternary structure: The aggregation of multiple polypeptide subunits.
What is the protein structure?Proteins are molecules composed of several amino acids.
Amino acids are monomers composed of
a central carbon, a hydrogen atom, a carboxyl group (COOH), an amine group (NH₂), and an R group.
The R group is what differentiates one amino acid from another one.
Several amino acids linearly arranged and connected by peptidic bonds compose the polypeptide.
The peptidic bond is the union of two amino acids by their carboxyl and amine groups.
The R group of each amino acid stabilizes the molecule through their interactions.
The amount of amino acids that compose the polypeptide and their order in the chain determines the primary structure of the protein. The primary structure of the proteins determines the tertiary one.
Protein functions also depend on the amino acid sequences. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.
The primary structure is basically, the sequence of amino acids in the chain. It refers to the amino acid arrangement.
The secondary structure is achieved through hydrogen bonds (between -CO- and -NH- groups), when the polypeptidic chain folds and different regions of the molecule get in touch. The molecule can adopt conformations like the alpha-helix and beta-sheet.
The three-dimensional structure involves a higher folding degree, in a tridimensional space. This level makes the protein even more stable in the environment and capable of accomplishing its functions.
The quaternary structure can be seen when proteins are composed of more than one subunit. The way in which these subunits arrange is the fourth structure.
The hydrophilic R-groups stay permanently in the molecule interior, avoiding interaction with water.

The heart pumps 2 ounces (71 grams) of blood at every heartbeat. The heart pumps 2,500 gallons (9,450 liters) of blood each day. The heart beats over three billion times in a person’s lifespan. Why does the heart muscles have great elastic strength?The heart is a four-chambered organ that is located in the center of the chest. The two upper chambers of the heart are called the atria, and the two lower chambers are called the ventricles. The atria receive blood from the body, and the ventricles pump blood to the lungs and the rest of the body.
The heart is a vital organ that is essential for life. It is responsible for pumping blood throughout the body, which delivers oxygen and nutrients to the cells and removes waste products. The heart is a strong and resilient organ, but it can be damaged by disease or injury. If the heart is not functioning properly, it can lead to a number of health problems, including heart failure, stroke, and heart attack.

that 150 could detect the bitter taste of PTC and 65 could not. Calculate the following frequencies.
A. The frequency of the recessive allele,
B. The frequency of the dominant allele.
C. The frequency of the heterozygous individuals.
Please show all work
Answers
The frequency of the recessive allele would be 0.55, that of the dominant allele would be 0.45, and that of the heterozygous individuals would be 0.495
Population geneticsRecall that for a population in Hardy-Weinberg equilibrium:
p2 + 2pq + q2 = 1
Also, p + q = 1
Where:
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p2 = percentage of homzygous dominant individuals
q2 = percentage of homzygous recessive individuals
2pq = percentage of heterozygous individuals
In this case, the percentage of homzygous recessive individuals can be calculated as:
Homzygous recessive = those that could not taste PTC = 65/215
q2 = 65/215 = 0.302
q = 0.55
Since p + q = 1
p = 1 - 0.55
= 0.45
The frequency of the heterozygous individuals = 2pq
= 2 x 0.45 x 0.55
= 0.495

example of a tissue each of a plant and animals
Answers
Answer:
Plants and animals took up different evolutionary pathway millions of years ago.
In the prebiotic earth, the CO2 levels were insanely high, and the solar input was quite high due to which the initially evolved cells were photosynthetic , so that they can harness the solar energy, and because they need a carbon source, they relied on the Carbon from CO2.
In this process, the atmospheric gaseous content changed, as predecessors of plants gave out Oxygen over millions of years.
Gradually , the atmosphere was now oxygen rich and hence predecessors of animals evolved a mechanism to utilise this oxygen , and as a byproduct started releasing CO2.
Over the next years , these two diverse groups specialised and hence , became increasingly different.

d.

Answers
Humans have a variety of alleles, which together with homologous partners make up the gene loci responsible for specific phenotypes. The geneticist Gregor Mendel discovered a phenomenon known as recessive/dominant, which describes how the effects of one allele can be obscured by those of another.
Given her recessive nose shape and dominant tongue characteristic, we can infer Elizabeth's genotypes from the description to be nnRR and nnRr. Because John has a dominant nose shape and a dominant tongue characteristic, his genotypes may be NNRR, NNRr, NnRR, or NnRr. It is necessary to check the genotypes of their offspring in order to determine their true genotypes. Of their four children, dominant (Ellen and Anne) and recessive (the other three) phenotypes of nose shape exist (Dan and Peter).Elizabeth's mother was a convex-nosed (dominant) non-roller and her father was a straight-nosed (recessive) roller (recessive). According to this description, Elizabeth's mother has the genotypes NNrr and Nnrr, whilst her father could have the nnRR and nnRr. Elizabeth's genotype is nnRr, as shown by the answer in letter a. Her mother and father each contributed one recessive n gene. As a result, Elizabeth's mother is Nn for the N allele. Due to Elizabeth's mother's recessive phenotype, her father's R allele can either be RR or Rr (rr). In conclusion, Elizabeth's mother is "Nnrr" and her father is "nnRR" or "nnRr".While his mother was a convex-nosed (dominant) roller, John's father was a straight-nosed (recessive) roller (dominant). According to this description, John's mother's genotypes are NNRR, NnRR, NNRr, and NnRr, whereas John's father's genotypes are nnRR and nnRr. John has the genotype NnRr, as shown by the response in letter a.If John's father has the genotype nnRR, his mother could have NNRr or NnRr.John's mother's genotype might be NNRR, NnRR, NNRr, or NnRr when his father has the nnRr allele.To know more about Gregor Mendel please click here : https://brainly.com/question/930312

In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and returns to the liver. In the liver, lactate is converted back into glucose by gluconeogenesis. For each given enzyme, identify whether it is involved in the glycolysis pathyway, gluconeogenesis pathway, both pathways, or neither pathway.
a. glyceraldehyde 3-phosphate dehydrogenase
b. phosphofructokinase-1
c. phosphoenolpyruvate carboxykinase
d. alcohol dehydrogenase
Answers
Answer and explanation:
Glycolysis and gluconeogenesis are metabolic pathways of great importance in the regulation of glycemia (glucose levels in the blood).
While glycolysis, a catabolic pathway that occurs when the glucose levels are high and is used to generate energy inside our cells; gluconeogenesis, an anabolic pathway, happens because glucose levels aren't high enough for our tissues to perform their energy-demanding tasks.
Glycolysis is stimulated by insulin and transforms 1 glucose molecule into 2 pyruvate molecules, which can then be further metabolized to produce ATP. Gluconeogenesis does the opposite: being stimulated by glucagon and epinephrine, it converts pyruvate molecules into glucose molecules to elevate glycemia.
Partaking in antagonizing pathways, glycolysis and gluconeogenesis appear to be the exact reverse pathway for one another, except for a few specific enzymes that are unique to each one of them.
a. glyceraldehyde 3-phosphate dehydrogenase - both pathways. This enzyme catalyzes the conversion of glyceraldehyde 3-phosphate into 1, 2 biphosphoglycerate, and backward.
b. phosphofructokinase-1 - glycolysis. This kinase phosphorylates (adds a phosphate group) fructose 6-phosphate into fructose 1, 6 biphosphate. In gluconeogenesis, the opposite reaction occurs thanks to the fructose 1, 6 biphosphatase (which removes a phosphate group from fructose 1, 6 biphosphate).
c. phosphoenolpyruvate (PEP) carboxykinase - gluconeogenesis. In glycolysis, phosphoenolpyruvate is transformed to pyruvate in one single reaction, catalyzed by enzyme pyruvate kinase. But in gluconeogenesis, pyruvate needs first to be converted into oxalacetate by the pyruvate carboxylase, so can then be transformed into phosphoenolpyruvate by the PEP carboxykinase.
d. alcohol dehydrogenase - neither pathway. Alcohol dehydrogenase is an enzyme that can be found in Ethanol metabolism, catalyzing the forming of acetaldehyde from an ethanol molecule.

The fertilizers show a significant impact on the nitrogen cycle as the fertilizers kill off the important nitrogen fixing bacteria which are present in the soil. Thus, the correct option is C.
What is Nitrogen cycle?Nitrogen Cycle is a biogeochemical process through which the nitrogen present in the environment is converted into many different forms, consecutively passing from the atmosphere to the soil to the living organisms and back into the atmosphere after decomposition. It involves several processes including the nitrogen fixation, nitrification, denitrification, decay and putrefaction of the nitrogen compounds.
Intensive fertilization of the agricultural soils of normal soil can increase the rates at which nitrogen in the form of ammonia is volatilized in the environment and lost to the air. It can also speed the microbial breakdown of ammonium and nitrates in the soil which results into enhancing the release of nitrous oxide. In addition to this, excessive use of fertilizers also kills the nitrogen fixing bacteria present in the soil.

The main regulatory sequences that are present in genes are Enhancers, Promoters, and suppressors.
The Promoter is a small DNA sequence on a gene, where the RNA (ribonucleic acid) polymerase enzyme can bind for the transcription of that gene. The prokaryotes have a -10 region (TATA box), as their promoter region, whereas the eukaryotes have -35 and – 10 regions as promoters. So, it does not have any effect on the level of gene expression. Enhancers are the DNA sequences, which enhance the gene expression; they are present above the promoter region. Thus, the removal of promoters cannot induce gene expression. Silencers are the DNA regions present below or above the promoter regions; they mostly silence or decrease the level of gene expression. Thus, the removal of silencer regulatory regions results in the over-expression of the genes.
