Receptors for neurotransmitters are of primary functional importance in assuring one-way synaptic transmission because they are mostly found on the Axonal membrane.

What are Neurotransmitters?

Neurotransmitters may be defined as the type of chemical substances that are correspondingly liberated at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction. They are released in the location known as the synaptic cleft.

The receptors of these neurotransmitters are present in the plasma membrane of postsynaptic cells which selectively bind the transmitter. They are integral membrane glycoproteins with multiple transmembrane segments.

Some examples of neurotransmitters may include serotonin, GABA, dopamine, acetylcholine, etc.

Rocks from the Ordovician Period contain evidence that plants began colonizing dry land at this time. Most experts agree that the ancestors of land plants first evolved in a marine environment, then moved into a freshwater environment and finally onto land.

Ordovician Period, in geologic time, the second period of the Paleozoic Era. It began 485.4 million years ago, following the Cambrian Period, and ended 443.8 million years ago, when the Silurian Period began. Ordovician rocks have the distinction of occurring at the highest elevation on Earth—the top of Mount Everest.

Prokaryotic Cells are unicellular organisms that don’t have a nucleus, but have their DNA unbound (or uncompressed) within the cells cytoplasm, they also have circular structures (or rings) called plasmids which carry additional Genetic Information.

Specific Example:  A bacterium is an example of a prokaryotic cell, and it has a cell wall, cell membrane, and even a capsule.

One feature that Eukaryotic cells have which Prokaryotic cells don’t is a Vacuole (this is just one feature).

Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and don’t have organelles. Many also have a capsule or slime layer made of polysaccharide (ignore this word if you havent learn about it yet).

the three steps that are required for dna replication are

Answers

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.

The three steps that are required for DNA  replication are initiation, elongation and termination.

What is DNA replication ?

The process in which DNA of a cell under go duplication to produce two copies during S-phase of cell cycle called as DNA replication.

It involves 3 steps such as initiation step where the origin of replication of DNA molecule undergo unwinding into two DNA strands.

An incomplete unzipping by forming replication fork is created is catalyzed by the helicase enzyme.

Secondly in elongation step the DNA polymerase enzymes make the complementary sequence against each parent template strand.  

It is an unidirectional, one strand which is synthesized in a continuous manner called leading strand, the strand which is synthesized in a discontinuous manner called lagging strand with Okazaki fragments.

Termination occurs in the last step, when the parent molecule has been completely replicated.

Choose all that apply. Which of the following is true in a comparison of your skin cells to your kidney cells?

1) conduct translation differently
2) contain different DNA
3) contain different chromosome
4) transcribe many different genes
5) conduct replication differently
6) have different transcription factors
7) contain different genes

Answers

Given our understanding of the mechanisms behind genetic expression, we can confirm that when comparing skin cells to kidney cells, the only correct option is option 4 which states that the cells "transcribe many different genes".

The human genome encodes for every gene in the human body. This genome sequence is stored in the chromosomes of cells. These chromosomes are identical for every single cell in the human body. Therefore, every cell contains the same DNA, genes, and transcription factors in its chromosomes.

What allows each cell type in the human body the ability to differentiate from one another and complete vastly different functions is the way in which these genes are expressed. Though every cell contains the entire genetic code, only some genes for each cell are transcribed, which results in a different combination of proteins in each cell and leads to the difference between skin and kidney cells (as just one of many examples).

What should be done with the contents of
a composter? Explain your reasoning.

Answers

Answer:

Finally, the number of times the pile is turned influences composting speed. By turning more frequently (about every 2-4 weeks), you will produce compost more quickly. Waiting at least two weeks allows the center of the pile to heat up and promotes maximum bacterial activity. The average composter turns the pile every 4-5 weeks.

When turning the compost pile, make sure that materials in the center are brought to the outsides, and that materials from the outside edges are brought to the center.

With frequent turning, compost can be ready in about 3 months, depending on the time of year. In winter, the activity of the bacteria slows, and it is recommended that you stop turning the pile after November to keep heat from escaping the pile's center. In summer, warm temperatures encourage bacterial activity and the composting process is quicker

Using compost in the yard

Incorporate compost into your garden as you prepare the soil in the spring. Cover the area with 3-4 inches of soil and till it in to at least the upper 6 inches of soil. Add compost to soil in vegetable gardens, annual flower beds, and around new perennials as they are planted.

You may also use compost as mulch around flower beds, vegetable gardens, or around trees or shrubs in landscape beds. Apply a 3 inch layer. Be careful not to apply mulch close to the main stem or trunk of the plant.

Which of the following sentences state a significant conclusion that Gregor Mendel drew from his experiments with pea plants? Traits are inherited in discrete units and are not the result of "blending." Genes are composed of DNA. Recessive genes occur more frequently in the F1 generation than do dominant ones. There is considerable genetic variation in garden peas.

Answers

Mendel concluded that the alternative forms of each trait are coded by discrete factors, which were called alleles that combine in pairs to express the trait. Traits are inherited in discrete units and are not the result of "blending."

------------------------

After making many crosses that involved different traits -such as plant height, or flower colors-, Mendel observed that, per trait, the F1 only expressed one of the alternative forms, while de other one disappeared.

Mendel named dominant the expressed variant.

Mendel then let these new plants auto pollinate and observed the results in the second generation, F2.

He saw that the variants that had previously disappeared among the F1, reappeared again. Both alternatives for each trait were present in the F2.

Mendel named recessive the second alternative variant.

Mendel explained his results by arguing that discrete factors were responsible for these phenotypes.

These factors should have been present in the F1 in pairs.

One of them came from one parental plant, and the other factor came from the other plant.

These factors separated again during sex cells formation, producing two types of gametes, each with only one factor.

Mendel conclusion about his experiments was that per trait -flower color of plant length-, each plant had a pair of factors -which he named alleles-, and that each factor coded for one of the alternative forms of the traits -white or purple, tall or short-.

He thought that alleles separate -segregate- during the process of gamete formation.

The First Mendel's Law is the first conclusion he took about his experiments and is known as the segregation principle.

dna is a double-stranded molecule made up of complementary, antiparallel strands. based on what you know about complementary base pairing, fill in the rest of the details in the figure.

Answers

The details in the figure correspond to the elements that the DNA strands have in their ends. Also, they correspond to the antiparallel strand with the complementary bases.

The DNA has two antiparallel strands with complementary bases (thymine, adenine, guanine, and cytosine). That is to say, that T pairs with A and G with C. Also, they have specific elements in their ends.

The 3' strand in its end has a hydroxyl (OH) group.The 5' strand in its end has a phosphate group.There is a complementary strand with its respective nucleotides that will pair with the other strand according to their specific bases (A-T; C-G)

In conclusion, the top left end of the 3' strand has a hydroxyl group, while the top right, the 5', has a phosphate group. The complementary strand will go the other way round, from 5' to 3', so the hydroxyl and phosphate groups would be on the right and the left, respectively. The bottom strand is the complementary one, and it runs from 3' to 5'.

The nutrients are distributed by the digestive system to the parts of the body that need them. B. The nutrients are picked up and transported around the body by blood from the circulatory system. C. The nutrients are absorbed directly into the cells that need them. D. The circulatory system brings nutrients to the digestive system to be processed for the cells.

Answers

Answer: c

Explanation:because it needs cells I think…

The nutrients from the food get to the cells of the body by the action of two organ systems i.e. the digestive system and the circulatory system.

What is the role of the digestive system?

The digestive system may be defined as a type of organ system that significantly deals with the breakdown of food substances into simpler components that can easily be consumed by the body.

According to the context of the question, the food that we eat reaches the stomach through the esophagus where multiple enzymes perform their roles. After the stomach, the food may be passed to the small intestine which is absorbed here and then the nutrients assimilate in the blood.

Through the blood, the nutrient can be transported around the body by blood from the circulatory system. Thus, the correct option for this question is B.
