Answer: Sodium sulphate
Explanation: Sodium sulphate is not an example of sublimate substance. Sublimation is the process in which there is a change of state directly from solid to gas without changing into a liquid state.
Answer:
Desublimation is a phase transition in which a gas changes directly to a solid without passing through an intermediate liquid phase.
It is an exothermic phase change that occurs at temperatures and pressures below a substance’s triple point in its phase diagram.
Desublimation is also called deposition.
Desublimation is caused by a drastic loss in thermal energy from the surrounding gas due to the presence of a much cooler surface.
For example, frost formation occurs on window surfaces during the winter seasons.
This window is at a much cooler temperature, this makes the water vapor in the surrounding air to lose enough thermal energy and change directly into solid which we see as frost during winter.

What is the term for the process by which mRNA is used to make a protein?
The term for the process by which mRNA is used to make a protein is "translation".
Translation is a key process in gene expression, whereby the sequence of nucleotides in mRNA is read and used to synthesize a protein. During translation, the mRNA is read by ribosomes, which use the sequence of nucleotides to assemble a specific sequence of amino acids into a protein. The sequence of amino acids determines the structure and function of the protein, and ultimately its role in the cell or organism.
The process of translation involves a complex series of steps, including the recognition and binding of mRNA by ribosomes, the selection and assembly of amino acids, and the folding and modification of the protein. Understanding the process of translation is essential for understanding the fundamental workings of cells and organisms, and has important implications for fields such as biotechnology and medicine.

The individuals selected for breeding have certain traits, which are determined by alleles.
• The alleles for selected traits become [more] common in a population as its genetic diversity decreases
What are alleles?Alleles are different versions of a gene that exist at the same location (locus) on a chromosome. Each individual inherits two copies of each gene (one from each parent), and therefore two alleles at each locus.
Alleles may differ in their DNA sequence, resulting in differences in the physical or functional characteristics of the trait they control. For example, the gene for eye color has different alleles that produce brown, blue, or green eyes.
The combination of an individual's alleles at a particular locus is known as its genotype, and the physical expression of the genotype is called its phenotype.

ASAP!!!A scientist designed an experiment to test where a plant's matter came from. She
measured the starting mass of a willow tree, the soil, and the container. After five
years, she repeated the measurements and observed that the tree gained 74 kg (164
lbs) but the soil had not changed much at all (only lost 57 g, approximately 0.12 lbs).
1. Use evidence, from the results, to explain that the idea that the mass of a tree
comes from the soil, is incorrect. 2 points
2. Why is it incorrect to say that the tree's mass comes from sunlight? 1 point
3. If the mass of the tree does not come from the soil or sunlight, explain the trees
increase in mass. 2 points
Explanation:
The fact that the soil did not change significantly after five years, while the tree gained 74 kg, suggests that the tree's mass did not come from the soil alone. If the tree had gained all its mass from the soil, the soil would have lost an equivalent amount of mass, which did not occur. Therefore, this evidence suggests that the mass of a tree does not come solely from the soil.
While sunlight is necessary for photosynthesis, which allows the tree to produce glucose, the mass of a tree does not come directly from sunlight. Rather, the tree uses the glucose produced during photosynthesis to build its own tissues, such as leaves, branches, and roots. Therefore, while sunlight is necessary for the tree to grow, it is not the source of the tree's mass.
The tree's increase in mass is primarily due to the process of photosynthesis. During photosynthesis, the tree uses energy from sunlight to convert carbon dioxide and water into glucose, which it then uses to build new tissues. Additionally, the tree may have also taken up nutrients, such as nitrogen and phosphorus, from the soil, which it incorporated into its tissues. However, it's important to note that the majority of the tree's mass comes from the carbon that it takes up during photosynthesis, rather than the nutrients in the soil.

A.action potential
B.stimulus
C.threshold potential
D.membrane potential
The threshold potential is the value at which a cell membrane must be more positively charged than negatively charged in order to produce an impulse.
Threshold potentialThe threshold potential is a crucial depolarization level that must be attained in order for a neuron to initiate an action potential or nerve impulse.
Voltage-gated ion channels in the membrane of a neuron open when the membrane potential reaches the threshold potential, enabling an influx of positively charged ions into the cell.
The result is a fast depolarization of the cell membrane, which generates an action potential that travels the entire length of the neuron.
It's crucial to understand that the threshold potential varies depending on the kind and location of the neuron, in addition to other elements like temperature and the presence of toxins or medications.

the relaxed pairing at the blank position of the codon and the blank position of the anticodon are blank and blank to follow the traditional base pair rules. this allows for a single trna to recognize multiple codons.
The relaxed pairing at the third position of the codon and the first position of the anticodon are wobble and able to follow the traditional base pair rules. This allows for a single tRNA to recognize multiple codons.
Relaxed pairing at the third position of the codon and the first position of the anticodon refers to the ability of the genetic code to tolerate non-standard base pairing between these positions during translation. Specifically, the third position of the codon (also known as the wobble position) can form non-Watson-Crick base pairs with the first position of the anticodon, allowing a single tRNA molecule to recognize and bind to multiple codons that differ only in this position. This phenomenon expands the coding capacity of the genetic code and helps to optimize the efficiency of protein synthesis.

Answer: This is because they might not have any predators or there NATURAL ENVIROMENT IS DIFFICULT to find or destroy
Explanation:
What is speciation? Describe the three things required.
Speciation is the evolutionary process by which new species arise from existing ones.
What is speciation?Speciation occurs when a group of organisms becomes reproductively isolated from the rest of their population, preventing gene flow between the two groups.
There are three key requirements for speciation to occur:
Genetic isolation: This occurs when a group of individuals becomes separated from the rest of their population, either geographically or ecologically, and is prevented from interbreeding with them. This can lead to the accumulation of genetic differences between the two groups.
Genetic divergence: Once genetic isolation occurs, the two populations can begin to evolve separately. This can happen as a result of genetic drift, natural selection, or other evolutionary mechanisms, leading to the accumulation of genetic differences between the two groups.
Reproductive isolation: Over time, the genetic differences between the two groups may become so pronounced that members of the two populations are no longer able to interbreed successfully, even if they are brought back into contact with one another.

Answer:
Encouraging food growth for export would be one way to discourage food sovereignty
Explanation:
.This is because if the focus is on exporting food, it may lead to a situation where the domestic market is neglected, and food production is not geared towards meeting local needs. This could result in food shortages and make the local population dependent on imported food. In such a scenario, the control over food production and distribution would lie with external forces rather than local communities, which goes against the idea of food sovereignty.
Do you think the adaptations of the animal you chose are a result of its environment, genes, or both? Explain your answer.
Answer:
The adaptations are result of both the environment and genes. Animal develop adaptive characteristics in response to their environmental challenges. These adaptations help the animals survive in their environment. The animals are more likely to reach reproductive age. So,these adaptive traits are more likely to be passed on to offspring.In the case of cheetahs,tan coloring,conservation of water, and fast legs are traits that help them survive in the savanna. These traits,like all the other characteristics of cheetahs,are genetically passed from parents to offspring.
