T/F: Restriction enzymes cut only at specific sites and therefore are not useful for microbial identification
FALSE

Answers

Answer 1

FALSE. Recombinant DNA technology and genetic engineering are only illustrations of the many scientific procedures that require restriction enzymes.

An bacteria were isolated protein called a restriction enzyme breaks DNA at specified sequence-specific places to produce DNA fragments with a series of known at each end. Researchers were able to separate gene-containing DNA fragments and recombine them with other DNA molecules to create genes by using enzymes that could cut DNA at exact spots. DNA is divided into smaller pieces in the lab using restriction enzymes or restriction endonucleases. Always, particular nucleotide sequences are the sites of the incisions. Different DNA sequences are recognized and cut by various restriction enzymes.

Answer:

The correct answer is -

C is parent cell

A is under meiosis

B is a sex cell

Explanation:

In the given question, the diagram shows three different cells in which the cell C is the parent cell that is about to undergo meiosis that can be identified by the quantity or numbers of chromosomes present in the cell which is highest among all.

The cell that is already in the meiosis is cell A, it is the cell that is produced after meiosis 1 in the meiosis cell division as it has half number of chromosomes to parent cells.

The sex cell or gamete is cell C that has a haploid number of chromosomes which makes this process reduction division

How does RNA polymerase determine which strand is the template/antisense strand?

Answers

Answer:

Although RNA polymerase must recognize sequences on the template strand, by convention we draw the DNA sequence and regulatory signals on the "mRNA-like" strand. (This makes it simpler to directly determine the sequence of the resulting RNA.) The upper strand of DNA is the "mRNA-like" strand.

If mRNA had the codon GUA, what amino acid does that code for?

Answers

Answer:

Valine

Explanation:

This question is describing the process of translation, which is the second stage of protein synthesis. Translation is the process whereby mRNA sequence is used as a template to produce an amino acid sequence or protein.

The mRNA sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. According to this question, using the genetic code provided for us in a tabular form in this question, a mRNA codon as follows: GUA will code for VALINE amino acid.

An ion of aluminum has a charge of 3+. The ion contains 10 electrons. How many protons does a neutral atom of aluminum possess?

Answers

Answer:

13 protons

Explanation:

Aluminum, which has a symbol of Al, is an element in group 3 of the periodic table. It has a mass number of 27. Since the number of electrons and protons in a neutral atom are the same, a neutral/uncharged atom of aluminum contains 13 electrons, 13 protons and 14 neutrons. Note: Mass number = no. of protons + no. of electrons.

However, according to this question, an ion of aluminum has a charge of 3+, this means that an atom of aluminum has lost 3 electrons i.e. 13 electrons - 3 electrons = 10 electrons. Hence, aluminum atom with charge +3 will have 10 electrons. This doesn't change the fact that aluminum atom in a neutral state possesses 13 protons.

From the act of pollinating flowers, a bee population gains the benefit of a 0.06 growth rate increase per month. However, the costs imposed by the flower (bees occasionally getting stuck, time spent pollinating the flower instead of pollinating other species, etc.) is a 0.02 reduction in growth rate per month. The flower gains benefits from the pollination that enhance its population growth rate by 0.05 per month, but it incurs costs (feeding the bees, damage done by the bees) that reduce its growth rate by 0.07 per month. Which of the following statements about the relationship between the bees and the flowers is true?
a. It is a host?parasite relationship in which the bees are the hosts and the flowers are the parasites.
b. It is a host?parasite relationship in which the flowers are the hosts and the bees are the parasites.
c. It is an amensalism
d. It is a commensalism.
e. It is a mutualism.

Answers

Answer:

Mutualism

Explanation:

All organisms in nature interact with other organisms in different ways. Symbiotic interactions involve a relationship between two or more organisms of different species in which one or all of them turn to be beneficiated by that relationship. These species create permanent mutual dependence.

Symbiotic interactions include:

Amensalism refers to a biological relationship established between two organisms, in which one of them avoids the growth, development, or survival of the other one. In this interaction, one of the organisms seems to be strongly affected by the other one. Meanwhile, the other organism does not seem to be affected at all.

Commensalism: In this case, the fitness of only one of the species seems to increase, while the other species is not affected at all, nor positively or negatively. The unaffected species might provide food or refuge to the other species, which is beneficiated.

Parasitism: In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness. These interactions are mainly about nutrition, although there might be other benefits too. Some parasite species might coexist with their host, while some others might get them ill to the point of causing death.

Mutualism: The interaction is favorable for both species. Their fitness increases with these interactions, although they do not need this relationship to survive. The degree of benefits might vary among species or might be equal.

In the relationship bee-flower, no one parasites the other. No one affects negatively the fitness of the other one. And both species seem to be equally beneficiated (bees find a source of food, and flowers get to be fertilized). This is a mutualistic relationship.

The color of an object that humans see is actually the ______ of light reflected off the object


Please answer !!!

Answers

Wavelengths


I’m pretty sure

An object's color is really determined by the light wavelengths that are reflected while all other wavelengths are absorbed.

What is light reflection?

In this context, color refers to the various light wavelengths in the visible light spectrum that are seen by human eyes.

An item is viewed as black if it absorbs all the hues of white light, as demonstrated in the following illustration. A white item will evenly reflect all shades of white light.

The light waves that an item reflects determine its "color." This is governed by the configuration of electrons in the atoms of that substance, which, in accordance with complex quantum principles, will absorb and reemit photons of a certain energy.

Therefore, an object that humans see is actually the wavelengths of light reflected off the object.

At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.

which of the following is least affected by seasonal environmental conditions?

Answers

Answer:

The seasonal environmental conditions are very poor , during summer season temperatures are very high.

The organism that is least affected by seasonal environmental conditions is a bacterium, as bacteria are single-celled prokaryotes that are capable of adapting to a wide range of environmental conditions.

What is the significance of bacterial and plant living conditions?

Bacteria can survive in extreme conditions such as high salinity, low pH, and other environmental conditions and can easily switch from aerobic to anaerobic metabolism depending on the availability of oxygen in the environment. Plants and animals are more sensitive to seasonal environmental conditions as they need temperature, light, water, etc.

Hence, the organism that is least affected by seasonal environmental conditions is a bacterium, as bacteria are single-celled prokaryotes that are capable of adapting to a wide range of environmental conditions.
