DNA contains thymine, double helix, longest chain of nucleotides, and deoxyribose. The mRNA binds to small subunits of ribosomes and carries the genetic code to the ribosomes.
Although it is written in a different chemical form, the information in RNA is basically written in the same language as it is in DNA, the language of a nucleotide sequence. Similar to DNA, RNA is a linear polymer composed of four distinct nucleotide component types that are joined by phosphodiester linkages.
Although RNA contains the bases adenine (A), guanine (G), and cytosine (C), unlike DNA, it also contains the base uracil (U), which replaces the base thymine (T) in DNA. The nucleotides in RNA are ribonucleotides that means they contain sugar ribose.

Photosynthesis is a vital biological process that occurs in plants, algae, and some bacteria.
How to write a research?Meaning of Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organism's activities. This chemical energy is stored in molecules of the sugar, glucose.
Definition of Photosynthesis
Photosynthesis can be defined as the process by which plants use sunlight, water, and carbon dioxide to produce oxygen and energy-rich carbohydrates.
Historical Perspective of Photosynthesis
The first recorded observations of photosynthesis were made by Jan Baptista van Helmont in the 17th century. Van Helmont found that when he weighed a willow tree before and after growing it for five years, the tree had gained a significant amount of weight, even though he had only added water to the soil. He concluded that the tree must have gained its weight from something other than water, and he hypothesized that the tree was obtaining its nutrients from the air.
In the 19th century, Joseph Priestley discovered that plants produce oxygen gas as a byproduct of photosynthesis. In the early 20th century, Calvin and Benson proposed a detailed model of the biochemical pathway of photosynthesis. This model, known as the Calvin Cycle, is still widely accepted today.
Importance of Photosynthesis
Photosynthesis is essential for life on Earth. It is the primary source of oxygen for the planet, and it provides the food for all living things that rely on plants for sustenance. Photosynthesis also plays a role in regulating the Earth's climate. By removing carbon dioxide from the atmosphere, photosynthesis helps to mitigate the effects of global warming.

based on the model, which of the following best explains how regulation of neurotransmitter release might increase the range of responses to a stimulus in the nervous system?
Based on the model, regulation of neurotransmitter release might increase the range of responses to a stimulus in the nervous system can be best described by (B) Different neurons in the same neural network can release different amounts of neurotransmitter.
In order to influence another cell across a synaptic gap, a neuron produces a chemical signalling agent known as a neurotransmitter. Any major body component or target cell that receives the signal may be another neuron, but it could also be a gland or muscle cell.
Each neurotransmitter has a distinct function in the brain and body. Although there are several minor and major neurotransmitters, we will concentrate on these six key ones: glutamate, acetylcholine, dopamine, norepinephrine, and serotonin.
Serotonin is a neurotransmitter that facilitates contentment, happiness, and optimism. The bulk of current antidepressants, known as serotonin reuptake inhibitors (SSRIs), work by reducing serotonin levels to treat depression while increasing serotonin availability to brain cells.

Answer:
\(\boxed {\boxed {\sf Desert}}\)
Explanation:
Let's evaluate the information given.
Large ears
This feature allows more heat to escape from the animal. A large ear=greater surface area= more blood vessels to release heat.Obtains water from food
In certain biomes, water is scarce. Animals can't obtain their water from drinking, so they turn to their food as a water source.Burrows underground during the day
Animals will hide underground to stay cool. It limits their exposure to the sun and heat.Based on this information, we can assume this is a desert animal. In the desert it is very hot (adaptations of large ears and undergrounds burrows) and there is little water (gets water from food).
Hypoxia is known to cause a disruption of somitogenesis. If a mouse embryo were temporarily exposed to low levels of oxygen during the final stages of somitogenesis, what would you expect to see in the vertebral column of the newborn mouse
In mammals, hypoxia may cause defects during fetal development. In this case, it would be expected to observe an abnormal development of the caudal (tail) vertebrae
Somitogenesis refers to the process during embryo development in which somites form. These somites are cells that will give rise to structures associated with the vertebrae body plan. Somites form sequentially from the head to the tail, where each new somite forms on the caudal or tail region of the previous one.Somitogenesis represents the first sign of segmentation of the developing vertebrate embryo. During somitogenesis, the unsegmented paraxial or presomitic mesoderm in the trilaminar embryonic stage is segmented in order to form pairs of somites. Moreover, caudal vertebrae refer to the bones that form the tail of vertebrates, which derive from caudal somites.Embryo hypoxia refers to the condition in which the developing embryo does not receive sufficient oxygen (O2) supply. It has been shown that hypoxia during embryo development can increase the incidence of malformations. In this case, embryo hypoxia affects normal caudal somite segmentation, thereby leading to defects in the caudal (tail) vertebrae.Learn more about this topic here:

Which of the following best describes a keystone species?
Can indirectly protect several other species in the same habitat
An organism, who if removed, the entire ecosystem changes
Can signal a change in the biological condition of a particular ecosystem and diagnose the health of that ecosystem
An organism, whose introduction causes or is likely to cause environmental harm
Answer:
An organism, who if removed, the entire ecosystem changes
Explanation:
A keystone species is a species which has a disproportionately large effect on its natural environment relative to its abundance, a concept introduced in 1969 by the zoologist Robert T. Paine. Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf, are also apex predators.
Tall pea plants are dominant, while short plants are recessive. In a cross between a purebred tall plant and a purebred short plant, the offspring will all be _______ plants.
Tall pea plants are dominant, while short plants are recessive. In a cross between two plants heterozygous for height, the offspring will be both tall and short in a _______ ratio.
Respond to the following based on your reading.
Explain why it's unknown which of two alleles an offspring will obtain from its biological mother or father for a given characteristic.
Reginald Punnett sought to apply the insights obtained by Mendel to explain the laws of inheritance in a structured fashion. What's a Punnett square and how is it used?
You're conducting a science experiment crossing two different purebred mouse strains, which each contain a different variation of the same gene, for two generations. What do you expect to see as the phenotypes of the first generation? The second generation?
How closely do Mendel's insights into dominant and recessive traits match up with the ratios that Punnett calculated in his Punnett squares?
Assuming complete dominance for all the genes, a) the offspring will all be Tall and heterozygous plants. b) 3:1 ratio. c) Punnett squares are used to combinate the parental gametes and make predictions about the possible genotypes and phenotypes among the progeny. d) First generation 100% heterozygous expressing the dominant phenotype. Second generation: 25% homozygous dominant + 50% heterozygous + 25% homozgous recessive. 75% expressing the dominant phenotype + 25% expressing the recessive phenotype. e) Mendel's insight and Punnett squares match perfectly with the expected ratios.
What are complete dominance and Punnett squares?
Complete dominance is an inheritance pattern that becomes evident in heterozygous individuals. The presence of at least one dominant allele is enougth to hide the expression of the recessive allele. In these cases, the individual expresses the dominant phenotype.
The Punnett square is a graphic representation that shows the different types of gamete combinations according to the alleles involved in a cross.
Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.
Tall pea plants are dominant, while short plants are recessive. In a cross between a purebred tall plant and a purebred short plant, the offspring will all be _TALL_ plants.All these plants will be heterozygous and express the dominant phenotype (Tall).
Tall pea plants are dominant, while short plants are recessive. In a cross between two plants heterozygous for height, the offspring will be both tall and short in a _3:1_ ratio.1/4 = 25% of the progeny are expected to be homozygous dominant
2/4 = 50% of the progeny are expected to be heterozygous
1/4 = 25% of the progeny is expected to be homozygous recessive
25% homozygous dominant + 50% heterozygous = 75% dominant phenotype

Explain the feedback mechanisms that control ventilation and circulation to include
the pacemaker of the heart.
It should be noted that the homeostatic feedback mechanisms that are important to regulate the ventilatory pattern of respiration involves the medulla and the pons.
Homeostatic feedback mechanisms.The pons are divided into two groups. Firstly, the pneumotaxic center sends signals that inhibit inspiration as it limits the activity of the phrenic nerve. Due to this, the signals of the apneustic center and the tidal volume decreases.
Secondly, the apneustic center signals inspiration for deep and long breaths and controls the intensity of breathing. The stretch receptors of the pulmonary muscles inhibit the apneustic center, therefore, it increases tidal volume.
Also, the medulla has two functional regions as well which are the ventral respiratory compartment, that stimulates expiratory movements, and the dorsal respiratory region that triggers inspiratory movements.

HELP PLEASE Name any two of the major types of chemical substances that are broken down in chemical digestion. For each substance, name an enzyme that breaks them down and what final product is actually absorbed by the body for use or storage.
Two major types of chemical substances that are broken down in chemical digestion are carbohydrates and proteins. Carbohydrates are broken down by the enzyme amylase, which is found in saliva and the pancreas.
Proteins are broken down by a group of enzymes called proteases, which are produced by the stomach and pancreas. Proteases break down proteins into smaller peptides and individual amino acids, which can be absorbed by the body and used to build new proteins or as a source of energy. Overall, the breakdown of carbohydrates and proteins in chemical digestion is crucial for the body to obtain the nutrients it needs for energy, growth, and repair. Amylase breaks down complex carbohydrates into simpler sugars, such as glucose and fructose, which can be absorbed by the body and used for energy or stored as glycogen in the liver and muscles.
