Whiteflies are common pest insects found on cotton, tomato, poinsettia, and many other plants. Nymphs are translucent and mostly sessile, feeding on their host plant's phloem (sap) from the undersides of leaves. They undergo incomplete metamorphosis into winged adults. Because whitefly nymphs cannot escape predation by moving, you hypothesize that their translucent bodies make them hard to spot by predators. How could you directly test this hypothesis?

Answers

Answer 1

Answer: Comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.

Explanation:

A hypothesis refers to an assumption, which is proposed for the sake of an argument which is tested to ascertain if it's true.

The hypothesis can be tested by comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.

Adenine, thymine, thymine, cytosine, guanine, and adenine is the correct order in which nucleotides add on single strand DNA.

What is DNA replication?

The process of DNA replication is crucial for cells to divide and create an exact copy of their DNA. Enzymes like helicase play a vital role in unwinding and separating the two strands of the double helix, creating a replication fork that serves as the starting point for this process. As DNA polymerase adds nucleotides to the new strand using the existing strand as a template, it follows specific rules of complementary base pairing: adenine (A) pairs with thymine (T), while cytosine (C) pairs with guanine (G).

What will be order of nucleotides to add on single strand of DNA?

During DNA replication, the order in which free nucleotides will add on to a single strand of DNA with the sequence ATTGCA is crucial. The correct sequence of nucleotides that will bind to this template strand is adenine (A), thymine (T), thymine (T), cytosine (C), guanine (G) and adenine (A). This follows the complementary base pairing rules where A pairs with T and C pairs with G. By following these rules, the newly synthesized strand will have a correct sequence of ATTTGC, ensuring accurate replication.

Earth's population over the centuries has risen at an increasing rate. So, the correct option is C.

How the population of Earth is increasing?

This sharp increase in population has been primarily caused by an increase in the proportion of individuals reaching breeding age, the gradual extension of human life expectancy, growing urbanization, and quickening migration. This expansion has been accompanied by significant changes in the fertility rate.

One of the key reasons for India's population expansion is a drop in death rates brought on by better medical services and a steady birth rate. The widespread illiteracy in India makes people believe that "children are god's blessings," which makes them opposed to the idea of "family planning." Earth's population over the centuries has risen at an increasing rate.

Therefore, the correct option is C.

Which of the following statements about active transport is true?

Molecules move down the concentration gradient.

ATP is not required to move molecules through the membrane.

ATP is formed as molecules pass through protein channels.

It results in a higher concentration of molecules on one side of the membrane.

Answers

Answer:

It results in a higher concentration of molecules on one side of the membrane.

Explanation:

Active transport is the transport of molecules up the concentration gradient. This means that molecules are going from low density to high density. This is the opposite of natural diffusion. So, it requires ATP to move the molecules this way. Diffusion normally occurs to maintain homeostasis and an equal amount of concentration on both sides of a membrane. But, with active transport, since molecules are moving up the gradient, the opposite happens and the concentrations are unequal.

Answers

Answer:

Mendel first observed the different patterns of gene segregation for selected traits in garden peas and was able to determine probabilities of recurrence of a trait for subsequent generations and analyses of large families with many affected individuals can be used to determine whether a disease-associated gene is located on an autosome or on a sex chromosome, and whether the related disease phenotype is dominant or recessive.

Listeriosis is of particular concern for pregnant women because pregnant women are more likely than other population groups to get listeriosis. listeriosis can cause fetal death. Listeria bacteria can cross the placenta and infect the fetus. All of the choices are correct.

Answers

Answer:

The correct answer is ''All of the choices are correct.''

Explanation:

Pregnant women are a risk group for listeriosis, the disease caused by the Listeria monocytogenes bacteria found in contaminated food. This organism can cross the placenta and affect the fetus. Due to the decrease in cellular immunity, pregnant women are part of the population at risk and are 17-20 times more likely to develop listeriosis after the consumption of contaminated food and it usually occurs from the third trimester and appears as a disease mild with not very high fever, joint and muscle pain. Listeriosis can cause miscarriages during the first three months of pregnancy. As the third trimester is reached, the mother is at greater risk. It presents a 40-50% fetal or neonatal mortality. In the first or second trimester it produces septic abortions and intrauterine fetal death, in the third trimester she produces chorioamnionitis and premature labor. In 1/3 cases it can occur asymptomatically in the fetus / neonate. In newborns, listeriosis can cause blood infections and meningitis.

If a tRNA molecule has an anticodon which reads AGGCCG, what was the codon on the mRNA molecule?

TCCGGA
UCCGGC
UCCGGU
CTTAAG

Answers

The codon is the sequence of nucleotides that carry genetic information that determines which amino acid should be added to the building protein. Nucleotides in this sequence pair with nucleotides from the tRNA  anticodon. In the exposed example, the correct codon pairing the given anticodon is is UCCGGC.

Before expplanation, let us review some theoretical frame to answer the question.

During protein synthesis, the ribosome reads mRNA in the 5´ to 3´ direction, while tRNA adds the correct amino acids to build the polypeptide, according to the codons readen in the mRNA chain. A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly. Each of the codons represents one of the 20 amino acids used to build the protein. Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid. tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.  

Once the new amino acid joins the growing protein, the binding between the amino acid and the tRNA breaks, releasing the molecule, which is now available to join another amino acid and repeat the cycle.  

Anticodon: Sequence of bases that pairs with the mRNA codon.  

Amino Acid: the amino acid that is codified by the mRNA codon.  

Remeber that:

Adenine forms pairs with Uracyl ⇒ A↔UGuanine pairs with Cytosine ⇒ C↔G

In the exposed example, the tRNA anticodon is AGGCCG, so we need to find its complement.

We know that Adenine pairs Uracyl, Guanine pairs Cytosine, and Cytosine pairs Guanine. So,

Anticodon → AGGCCG

You farm kelp and sell the kelp for food and as fertilizer. The wastes from the kelp can be used in an integrated aquaculture system in which kelp farming can be coupled with farming of fish or abalone. Make an argument that you are using a sustainable system of growing a renewable resource, and explain why it is beneficial (and more sustainable) to couple algae farming with fish farming than simply to farm fish independently.

Answers

Answer:

A sustainable system refers to producing less or probably non-existent debris that are caused by the production of a particular material (i.e. produce, energy). This is a sustainable form of production of coupling algae growth and fish farming because you no longer need the supply of fish feed from other sources that are made artificially but rather, you are using the available algae growth that you are culturing. Farm fishing alone is non-renewable because this produces much waste that can directly harm the environment.

An integrated aquaculture system of fish farming with kelp farming is a sustainable system as both system exchange resources and thus reduce wastage of resources.

What is an integrated aquaculture system?

An integrated aquaculture system is an aquaculture system which combines several forms of aquaculture together.

For example, kelp farming is a form of aquaculture which can be integrated with another form of aquaculture such as fish farming.

Integrating fish farming with kelp farming is a sustainable system as both system provides what the other needs.

The kelps serve as food to fish while fish waste serve as manure for kelps.

Therefore, integrating fish farming and kelp farming is a form of a sustainable system.
