3.Each onion plant begins as a single cell containing 16 chromosomes. How many chromosomes are present in each of the cells that you observed

Answers

Answer 1

Answer:

In somatic cells, 16 chromosomes are present whereas in sex cells, there is 8 chromosomes.

Explanation:

In the somatic cells, the replication of chromosomes occur and after the replication is completed, the parent cell is divided into two daughter cells having double number of chromosome by each daughter cell i.e. 16 chromosomes while on the other hand, in sex cells, first the parent cell divides into two daughter cells and after sometime, these daughter cells are again divided having total four daughter cells each receives half number of chromosomes i.e. 8 chromosomes.

either from the brink of extinction or from extinction)? Explain your answer.

Answers

No, God gives and takes away, the world is heartless and kills entire species to extinction but it’s nothing that God didn’t already know would happen. Dinosaurs are no longer here there extinct for a reason, nowadays extinction comes from man but everything that happens in this world is Already written out in Gods book

Answer:

I think we should but people are preventing this though

Explanation:

I think we should because it might benefit the world and let scientists to discover this animal. But then I don't think so because animals that are/were extinct could perhaps be from climate change. Nowadays, people don't take this matter seriously causing habitats to be destroyed and animals to be extinct :) Like icebergs are melting that mean penguins are at risk of being extinct,if we did something then this situation will be prevented. However dinosaurs did become extinct and they did not come back so its probably just life and this is how god planned it:)

Given the latitudinal differences in sunlight intensity, how might you expect the carrying capacity of a plant species found at the equator to compare with that of a plant species found at high latitudes? Explain your answer

Answers

Answer:

The carrying capacity of a plant species expect in the equator is higher as compared to the carrying capacity at high Latitudes. This is due to the equator the plants have more light available, so the ecosystem can give them better conditions to survive and reproduce. Remembering that the carrying capacity is the largest population size an ecosystem can support without degrading itself, in the equator would be higher as it can have better conditions of light, so they would survive and reproduce more and the largest population the ecosystem could support would be higher.

The following statement is incorrect as stated "Pesticides create pesticide resistance in mosquitoes." Rewrite this sentence so that it is a more accurate statement of what actually occurs when pesticides are used. Why is this concept important to know in trying to control outbreaks of mosquito transmitted diseases such as eastern equine encephalitis (also known as Triple E)?

Answers

Answer:

Mosquitoes usually become resistant to pyrethroids through the mutation of a sodium channel gene that controls the movement of ions across cell membranes. Mutations in a single gene are enough to make mosquitoes almost completely resistant to the level of pyrethroids used in insecticides.

Answers

Answer:

The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of melatonin.

Explanation:

Melatonin is a hormone produced naturally by the body. Its function is to regulate the body's circadian cycle. This hormone is stimulated and begins to act by changing between a light environment and a dark environment. This stimulation interacts with the suprachiasmatic nuclei making the nervous system understand this change and luminosity of the environment and respond to the action of melatonin.

Enter the sequence of the DNA coding strand with a 5-3 polarity. DO NOT WRITE 5 OR 3 OR 5' OR 3' IN THE BOX!

Answers

Complete question:

Use the sequence below to answer the following questions  

3’-ACGGATCCTCCCTAGTGCGTAATACG-5’  

5’-TGCCTAGGAGGGATCACGCATTATGC-3’  

1. Enter the sequence of the coding strand with a 5’-3’ polarity

Answer:

coding strand → 5´- GCATAATGCGTGATCCCTAGGCA -3´

Explanation:

When referring to the coding strand, we are talking about the sequence that turns to be the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.  

The coding strand receives that name because it is the sequence that codes for each amino acid composing the proteins.

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand.  

The coding strand goes in direction 5´ to 3´, while the complementary strand -template strand- grows in direction 3´ to 5´.  

Whenever we have a DNI molecule and we need to determine which strand is the coding one, we just need to look for the presence/absence of start or stop codons.

So, in the exposed example we have two strands, but we do not know yet which one is the coding one.

Conventionally, the first strand is always the coding one. However, let us analyze it by using the presence/absence of codons.

First-strand:

3’-ACGGATCCTCCCTAGTGCGTAATACG-5’

let us write it is 5´to 3´direction

5´- GCATAATGCGTGATCCCTAGGCA -3´

now let us identify the start and stop codons in 5´⇒3´direction.

Start codon ⇒ ATGStop codon ⇒ TAA, TAG, TGA

5´- GCATAATGCGTGATCCCTAGGCA -3´ ⇒ 1 start codon at the beginning

5´- GCATAATGCGTGATCCCTAGGCA -3´ ⇒ 3 Stop codons

Second strand: We will do exactly the same procedure

5’-TGCCTAGGAGGGATCACGCATTATGC-3’⇒ 1 start codon near the end

5’-TGCCTAGGAGGGATCACGCATTATGC-3’⇒ 1 stop codon at the beginning

What we did here was to identify in both provided strands, where the start and stop codons are placed. We can see that in the first strand we have the start codon near the beginning, while in the second strand we have it near the end of the sequence. From this information, we can assume that the first strand is the coding one. However, you need to know that some coding sequences do not have start and stop sequences, because they might correspond to a sequence in the middle of a gene.

So, the sequence of the DNA coding strand with a 5-3 polarity is

5´- GCATAATGCGTGATCCCTAGGCA -3´

Explanation:

The respiratory system may be a system consisting of specific organs and structures used for gas exchange in animals and plants.

What is the process of respiration?

We have a pair of external nostrils opening out above the upper lips. It results in a nasal chamber through the nasal passage. The nasal chamber opens into the pharynx, some of which are the common passage for food and air. The pharynx opens through the larynx region into the trachea.Trachea is a straight tube extending up to the mid-thoracic cavity, which divides at the extent of the 5th thoracic vertebra into a right and left primary bronchi. Each terminal bronchiole gives rise to a variety of very thin, irregular-walled, and vascularized bag-like structures called alveoli. The branching network of bronchi, bronchioles, and alveoli comprise the lung.

Thus, we can conclude that the correct option is (e).

The oral cavity to the nasopharynx to the trachea to the right and left main bronchi.
