The polar region (arctic and antarctic circles) is cold all year and experiences low precipitation.
What is the polar region?Any location on Earth that lies between the North or South Pole and the Arctic or Antarctic Circles is referred to be a polar region. The Arctic Ocean and a portion of several nearby land masses are included in the northern polar area, sometimes known as the Arctic.
Extremely cold temperatures, heavy glaciation wherever there is enough precipitation to create permanent ice, brief and cold summers, and extreme variations in daylight hours, with 24 hours of daylight in the summer and total darkness in the middle of the winter, are all characteristics of polar regions.
Hence, the polar region (arctic and antarctic circles) is cold all year and experiences low precipitation.

Answer and Explanation:
When mRNA leaves the nucleus and meets a free ribosome in the cytosol, it starts the protein building. Ribosomes read the mRNA code and begin protein synthesis by adding the correct amino acid using transference RNA.
Ribosomes attached to the RER membrane are responsible for synthesizing membrane proteins, exportation proteins, or enzymes.
The synthesis of proteins destined to become enzymes, membrane proteins, or exportation proteins starts in the cytoplasm with the production of a molecule portion known as a signal aminoacidic sequence. This signal sequence in the amino extreme of the synthesizing protein, and when it reaches a certain length, it meets the signal recognizing particle that leads the synthesizing protein and associated ribosome to the Rough endoplasmic reticulum, where it continues the protein building until finishing the elongation process. When the new protein synthesis is complete, the polypeptide is released into the reticulum lumen, suffering a few posterior steps related to conformation and structure, such as folding to become functional and the initial glycosylation stages.
The new proteins get packaged into vesicles that carry them to the Golgi complex where occurs the final association of carbohydrates and lipids with proteins, to originate glycoproteins and glycolipids.
Enzymes destined for exportation are packaged and sent from the Golgi complex to the cell membrane into vesicles. When the secretory vesicle reaches the target, its membrane fuses with the cell membrane, releasing its content to the extracellular space. This secreting process is known as exocytosis.

Explanation:
A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. His measurements are shown in the graph below.
Graph shows heat, measured in Joules, radiated from an aquarium over time, measured in seconds. At 0 seconds, the energy, in the form of heat, is 1.2 Joules. At 5 seconds, the energy is 1.6 Joules. At 10 seconds, the energy is 1.3 Joules. Finally at 15 seconds, the energy is 1.5 Joules.
Based on this data, he concludes that the aquarium cannot be considered a closed system for this experiment. Explain why this conclusion is invalid.
A closed system exchanges both matter and energy with its surroundings, and the scientist only measured the exchange of heat.
A closed system can exchange energy but not matter with its surroundings, and the scientist did not measure the movement of matter.
A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.
A closed system exchanges all of its matter with its surroundings, and the scientist did not measure the movement of matter.
Answer:
The correct answer is - A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.
Explanation:
The amount of heat radiated is measured and analyzed by the marine biologist in this given experiment from an aquarium and on the basis of data the diagram is represented that states that the radiated energy is not constant over time and there are fluctuations.
It can not be considered as a closed system as energy is still exchange with the surrounding system, however, mass is not exchange but still, it cannot be called a closed system.

How are eukaryotic cell walls different from bacterial cell walls?
Explain the differences between eukaryotic and prokaryotic cells.
Explanation:
Comparing prokaryotes and eukaryotes
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.
which is not true about the first 22 pairs of chromosomes in a karyotype
they determine the gender of the individual
each pair has one chromosome from the father and one from the mother
they are called autosomes
they are homologous meaning each pair has the same size shape, and collection of genes
Answer:
The correct answer is - they determine the gender of the individual.
Explanation:
Autosomes are the chromosomes that are numbered or non-sex chromosomes. In humans, there are 22 pairs of autosomes that are numbered from 1 to 22. These chromosomes regulate or control the pattern of inheritance of every characteristic or trait of an organism other than present on the sex chromosomes.
These are homologous chromosomes which means each pair has the same genes and has a similar shape. The gender of an individual depends on the sex chromosome only.

Hide Assignment Information Instructions INSTRUCTIONS You are bird hunting moths (both dark and light) that live on trees. As you capture the moths most easily visible against the tree surface, the moth populations change, illustrating the effects of natural selection. In this Lab, you will: Predict the color of moth that will survive better on various colors of tree trunks. Understand how camouflage can promote survival. Explain the process of natural selection.
Answer: The theory of natural selection suggests that some members of the population of species have better advantage of others for survival in terms of better phenotypic traits.
Explanation:
According to the given situation, the moths which have color that remain undetected by me as bird has a phenotypic advantage. As I may not be able to observe them on tree trunk or bark or on leaves I can eat only those moths that can be seen through my eyes. I can capture them easily. Such moths which can change their colors in accordance with the color of the tree can camouflage me easily and I cannot observe them and consume them. This promotes their survival over those detectable moths.
Q.Why are some diabetes patients treated by giving insulin injections ?
Q. The gap between two neurons is called ------.
➜ The insulin hormone controls the metabolism of sugar. When pancreas does not produce or secrete sufficient amount of insulin into blood, then the sugar level in the blood rises. Therefore, the patient excreates sugar (glucose) in urine, feels excessive thirst and also urinates excessively. The people having severe diabetes are treated by giving injections of insulin.
➜ Synapse.
Insulin injections are given to individuals suffering from type 1 or type 2 diabetes. It is used when oral medication becomes ineffective. Insulin injections work by helping to move sugar from the blood into the body's cells. Moreover, it also inhibits the liver from producing more sugar.
