if you step on a sharp object muscles in your leg will rapidly put your foot away.

what is the correct term for this type of reaction?

Answers

Answer:

Explanation:

Sharp object the reaction is a reflex its involuntary and it doesn't involve ur brain it protects u from damage.So u step on the sharp object whihc is a stimulus so the reaction is reflex its quick and automatic.

Hope this helps

Reflex arcs can also be more complex. For example, consider what happens when you step on a sharp object. As in the example above, a sensory (pain) neuron carries an impulse to an interneuron in the spinal cord. The interneuron synapses with motor neurons which pull your foot away from the sharp object, just as in the example above. However, if that was all that happened you would probably fall over! The interneuron also synapses with motor neurons which control the muscles of the other leg. These muscles adjust your position so you do not fall. The interneuron synapses with still other neurons, which carry the information about what has happened to the cerebellum (which coordinates the muscular activities) and the cerebrum, so that you become "conscious" of what has happened and can take further voluntary action.

DNA strands run in 1 of 2 directions depending on which end of the strand is free and which end has a phosphate bond. One direction is 5' to 3' (__________) and the other direction is 3' to 5' (downstream). __________ polymerase binds to the DNA at the TATA box and unzips the double helix. Working along the DNA chain, RNA polymerase reads the DNA nitrogenous bases and matches RNA nitrogenous bases from the nucleus (uracil instead of thymine). As it moves, RNA polymerase re-zips the DNA behind it and lets the mRNA separate from the DNA. It continues to do this until it reaches a sequence downstream called a __________ signal. In other words, RNA polymerase copies the DNA sequence downstream of the TATA box into an mRNA strand.

1. Upstream

2. RNA

3. Terminator

Explanation:

This question is describing the process of transcription, which is the process whereby DNA template is used to synthesize an mRNA molecule. Transcription involves three stages viz: initiation, elongation and termination.

- DNA strands run in 1 of 2 directions depending on which end of the strand is free and which end has a phosphate bond. One direction is 5' to 3' (UPSTREAM) and the other direction is 3' to 5' (downstream). An enzyme called RNA polymerase binds to the DNA at the TATA box and unzips the double helix (INITIATION).

- Working along the DNA chain, RNA polymerase reads the DNA nitrogenous bases and matches RNA nitrogenous bases from the nucleus (uracil instead of thymine). As it moves, RNA polymerase re-zips the DNA behind it and lets the mRNA separate from the DNA (ELONGATION).

- It continues to do this until it reaches a sequence downstream called a TERMINATOR signal (TERMINATION). In other words, RNA polymerase copies the DNA sequence downstream of the TATA box into an mRNA strand.

Explanation:

Meiosis makes genetic variety possible. It makes sperm & egg cells called gametes. Each gamete has 23 chromosomes. To make a diploid cell two gametes (sperm & cell) come together.

During prophase 1 the chromosomes pair up with their homologous pairs so they can transfer their genetic information and exchange it between each other. It makes recombinant chromosomes that influence the genetic diversity between the same people.

Now they are in metaphase 1, the chromosomes are in pairs in the middle of the cell. In anaphase 1, the chromosomes are pulled away by the spindle fibers. Then in telophase 1, there are two formed nuclei. Cytokinesis 1 then splits the cytoplasm.

Now they are in meiosis 2. During prophase 2, there are chromosomes and the spindles are starting to form again without crossing over like in prophase 1. In metaphase 2, chromosomes are going to line up in the middle in both cells unlike during metaphase 1 where the chromosomes were only in pairs. In anaphase 2, only the chromatids are being pulled away by the spindle fibers. Next in telophase 2 the nuclei reform and the 2 cells are each going to divide into 4 cells. Finally, cytokinesis completely splits the cytoplasm.

Keeping in mind that each sex only produces one type of gamete cell (sperm or eggs), and of the independent assortment and crossing over of chromosomes, the end result will be diversity.

According to the data in the table, what percent of the elodea cells is water? Explain how you arrived at this conclusion.

Answers

Answer:

99%

Explanation:

at a salt solution concentration of 2%, plasmolysis first started to occur. So the other 98% in the "solution" would have just been water. Since water inside cells needs to be greater than the amount of water outside the cells, we can say that the amount of water inside the elodea cells was 99% so that it can allow hypertonic plasmolysis to occur.

Molecules of DNA are composed of long chains of?

Answers

two long polynucleotide chains

A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together

Molecules of DNA are composed of long chains of nucleotides.

What are nucleotides?

Nucleotides are the building blocks of DNA and RNA adenine (A), thymine (T), guanosine (G), and Cytosine (C. In RNA, uracil (U) is present instead of thymine.

The pentose sugar is the ribose sugar in RNA and deoxyribose sugar in DNA. In deoxyribose sugar, oxygen is absent from the 3' carbon.

Phosphate groups are attached through the 5-C of pentose sugar by an ester bond. One polynucleotide chain is formed when the phosphate of one nucleotide forms a phosphodiester bond with the sugar of another nucleotide.

A double-stranded structure is formed by base pairing between nucleotides. The adenine binds to thymine by two hydrogen bonds and guanine binds to cytosine by three hydrogen bonds.

Therefore the molecules of DNA are composed of long chains of nucleotides.

Color blindness is a X-linked recessive trait. A couple want to predict whether it would be possible for their child to be color blind. The female is an unaffected carrier and the male is red/green color blind. What percentage of offspring would be color blind?

Answers

Answer: There is a probability (n.b. NOT certainty) that half of all offspring will be colour blind.

Explanation: The female is XX and as an unaffected carrier we can assign genotype Cc where c is the recessive allele.

The male is XY and colour blind, so genotype cY

Male offspring can be cY or CY so p|colourblind = 50%

Female offspring can be Cc or cc so, again p= 50%

If there is also equal probability of sex of the offspring, there is an overall probability that half the offspring will be colour blind

Answers

Answer:

Cytokinesis,

Explanation:

Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase.

The division of the cytoplasm, which follows Mitosis, is called Cytokinesis. This is further explained below.

What is Mitosis?

Generally, Mitosis is simply defined as a kind of cell division that produces two daughter cells with the same number and type of chromosomes as the parent nucleus, as seen in normal tissue growth.

In conclusion, Cytokinesis is simply defined as the division of the cytoplasm that occurs after mitosis to produce two daughter cells.
