Can someone tell me what's the syllabus taught in American high schools, like in 10th grade? I'm not an American student and I'm just curious. (didn't mean to sound creepy). thank you so much.
Before higher education, American students attend elementary and high school for a combined total of 12 years. These years are known as the period from first grade to twelfth grade.
At the approximate age of six, American children begin elementary school, which is exclusively called “elementary school” (elementary school). They attend this school for five or six years and then go on to high school.
High schools are made up of two programs: the first is called "middle school" or "high school" (middle school) and the second is called "high school" (high school). A diploma or certificate is awarded upon graduation from high school. Upon graduation from high school (twelfth grade), American students can go on to college or university. Studies at a college or university are known as "higher education."
How do viruses disrupt homeostasis in their host?
Answer:
Hence, during infection in vivo, a noncytopathic virus may turn off the "differentiation" or "luxury" function of a cell while not killing that cell (loss of vital function). This is turn can disrupt homeostasis and cause disease

Can you describe a frogs metamorphosis, including whether it is complete or incomplete
Answer: frig metamorphosis is complete
Explanation:
This is because in complete metamorphosis, frog develop from egg to adults. Metamorphosis refers to change of shape and growth in different stages of animals life cycle.
Frog mate in the rainy season.
There are four stages of frog metamorphosis and they are;
1 Egg : the female mate with the male and the male fertilizes the egg. The female releases the fertilized egg inside water , they egg are jelly like or cover with jelly covering.
2. Tadpole: the egg then hatched into tadpoles. The tadpoles live in water, it does not have lungs and limbs. It move like fish and uses gills to breathe. At this stage it starts developing hind limbs and later lungs. It has long tail
3. Froglet : At this stage, the lungs and the front legs develop. It floats above the water to breathe. The tail become shorter and it uses nutrients stored in the tail to feed or survive.
4. Adult : this is the final stage, the young frog leave water and start live on land, it's tail disappear completely and it's start feeding on insects.
In 2015 what two space objects did New Horizons photograph?
Answer: I think collecting data on Pluto and Charon (the Charon flyby was at about 17,900 miles or 28,800 kilometers), New Horizons also observed Pluto's other satellites, Nix, Hydra, Kerberos and Styx.Also In July 2015, NASA's New Horizons became the first spacecraft to visit dwarf planet Pluto. The far-traveling spacecraft also flew by an object called 2014 MU69, or Ultima Thule, in January 2019. Observations from New Horizons are revolutionizing our understanding of solar system objects orbiting far from the sun.

Hello! I have to write an essay based on the Water Cycle and what it is/does. I will give Brainliest for the correct answer. I will also give 20 points to whoever writes the essay, and has the correct answer. Good luck.
Answer: The water cycle also known as the hydrolic cycle describes the always foward rotation above and below the surfaces of the earth. The mass of water on earths surface remains fairly consistant. However, the water splits up into diffrent groups, freshwater, saline water, ice, and atmospheric water. The water can travel between catorgories such as river to ocean or ocean to atmosphere through evaporation, condensation, precipatation, surface runoff and subsurface flow. When water go through these physical process it can change aswell such as being a liquid, solid,and gas. During evaporation it takes water from it surroundings and cools its enviromwnt,
the exchanges in heat fluctuate the climates tempature.

C.Different alleles form parents
D. Same genes from parents
Answer:
The word "heterozygous" simply means that your biological mother and your biological father, when they contributed their copies of a particular gene to you, they did so in a way so that the DNA sequence is slightly different. It can be different at one point in the gene, or it can be different at dozens and dozens of different points in the gene. i know it is B because the web showed me something that told me b but it would not let me submit that
so it is B

What 3 systems get put to work when a beaver is building a home and how?
Answer:
beaver dams smooth out water flow by increasing the area wetted by the stream. This allows more water to seep into the ground where its flow is slowed. This water eventually finds its way back to the stream. Rivers with beaver dams in their head waters have lower high water and higher low water levels.

90% H2O 10% Solute The solution is: hypertonic / hypotonic / isotonic Water will: not move / move into the cell / move out of the cell
Answer:
Hypotonic / moves into the cell.
Explanation:
Hope you have a nice evening.
The solution is hypotonic. Water will move into the cell.
What is hypotonic solution?A hypotonic solution is one where the concentration of solutes outside the cell is lower than the concentration inside the cell. In this case, the solution is composed of 90% water and 10% solute, which is a lower concentration of solutes than inside the cell.
As a result, water will move into the cell in order to balance the concentration of solutes and maintain homeostasis. This can cause the cell to swell and may even lead to lysis if the cell is unable to handle the increased volume.

Altos niveles de ATP en la célula son necesarios para realizar ciertas funciones vitales tales como reproducirse.A qué piensas que se deba esto
Answer:
el ATP es la moneda energética que la célula utiliza para llevar a cabo diversas funciones metabólicas (incluida la reproducción)
Explanation:
La adenosín trifosfato (ATP) es la principal fuente de energía para la mayor parte de los procesos celulares. La hidrólisis del ATP libera energía química almacenada en los enlaces de fosfato de la molécula, la cual es utilizada por la célula para llevar a cabo diversas funciones, incluida la reproducción. La hidrólisis de ATP genera en primera instancia adenosín difosfato (ADP) y un grupo fosfato libre (ortofosfato), esta es una reacción exergónica que libera una enorme cantidad de energía la cual es utilizada por la célula para llevar a cabo diversas funciones metabólicas incluyendo la síntesis de macromoléculas tales como, por ejemplo, proteínas del huso mitótico requeridas durante el proceso de división celular. El ADP también puede hidrolizarse para liberar energía, con la consecuente producción de adenosín monofosfato (AMP) y un segundo fosfato libre.

How does DNA send it's instructions to the other parts of the cell?
Answer:Through mRNA, the DNA is able to transmit its messages out to other parts of the cell. (Learn more about mRNA here.) Information from the DNA is coded into mRNA which leaves the nucleus of the cell DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies (the white region) and is used by ribosomes (outlined in green). hope this helps have a great night ❤️❤️❤️
Explanation:
What is the process of mRNA creating a protein?
In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. ... The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein. Figure 2: The amino acids specified by each mRNA codon.
Answer:
This process is called protein synthesis, and it actually consists of two. The enzyme is ready to make a strand of mRNA with a complementary sequence of bases.

A. Describe the role of the promoter in eukaryotic gene expression. Explain how a negative regulatory molecule could inhibit transcription at the promoter.
B. Identify TWO events that occur during RNA processing. Explain how RNA splicing increases the variation of mRNA molecules.
C. Describe the role of miRNA in gene expression.
Answer:
Explanation:
A. The role of promoter in eukariotic gene expression is It is to bind transcription factors that regulate transcription initiation. This molecule is so important because control the binding of RNA polymerase to DNA. The promoter region may be short or very long; the longer the promoter is, the more protein binding space is available. A negative regulatory molecule has the possibilty to inhibit transcription at the promoter because these molecules block the binding of RNA polymerase to the promoter region, thus not allowing the initiation of transcription, in some particular cases, the negative regulator binds to the lac repressor and will bind to the promoter in the same site where RNA polymerase would bind to.
B. Two process that occur during RNA processing are RNA splicing and 5′ capping, 3′. RNA splicing is a procces known for removing the introns from the pre-RNA and stuck back together the restant parts, exons. This process has as a goal form a mature mRNA that does not contain the intron sequences. RNA splicing has effect on variation of mRNA molecules because through a process called alternative splicing more than one mRNA can be made from the same gene.
C. Even though they are not quite the same thing miRNA and negative regulatory molecules have the same role, which is inhibit the translation and silence genes. They regulate gene expression by binding to the 3'-UTR of their target mRNAs and destabilizing the mRNA and translational silencing, repressing protein production. Even so, under specific circumstances, miRNA can activate translation or regulate transcription.
