If a DNA codon changes from TTA to TTC, what amino acid would the matching mRNA sequence code for?
Answer:
TTC codon encodes for Phenylalanine (Phe)
Explanation:
A codon (also known as a nucleotide triplet) is a sequence of DNA or RNA composed of three consecutive nucleotides. During protein synthesis, each codon specifies a particular amino acid or stop signal (i.e., termination codons). There are 64 possible codons, 61 encode for amino acids, while three (3) codons represent stop signals (e.g., UAG, UAA, UGA). In this case, TTC (i.e., UUC codon in the mRNA) codon encodes the amino acid Phenylalanine, while TTA (i.e., UUA codon in the mRNA sequence) codon encodes the amino acid Leucine.
Suppose Stephen breeds flowers and wants to optimize production of offspring with both short stems and white flowers, which are coded for by two genes with the recessive alleles t and p, respectively. In flowers, T codes for tall stems and P codes for purple flowers. Stephen crosses two heterozygotes that produce 544 offspring. How many of these 544 offspring are predicted to have both short stems and white flowers

In order to improve crop yields, the Green Revolution employs improved irrigation techniques, the addition of
synthetic fertilizers, new crop varieties, and mechanization.
All of the following accurately describe mechanization EXCEPT
Answer:
Mechanization is used for tillage practices.
Explanation:
Mechanization is an important factor that contributes in the Green Revolution because the using machines for the softening of soil enhances root penetration in the soil as well as aeration in the soil. Mechanization involves all the machines that is used for tillage practices such as cultivator, rotavator, chisel plough etc. The use of these machines enhances production of the crop that leads to Green Revolution.

How do icebergs contribute to rising sea levels?
○ They melt and increase the amount of water in the ocean.
○When they increase in size, they take
water out of the ocean.
○They break away from land, displacing significant amounts of water.
○The number of icebergs has been increasing, taking up more space in the ocean
In my knowledge
its option A
they melt and increase the amount of water in the ocean
Answer:
Its C -displacement
Explanation:
The other answer is wrong. It's just like when ice cubes melt in a cup the water level doesn't rise but instead, it increases the volume of the water in the cup by displacing it.
Which conclusion is supported by the fact that meat-packers cannot sell meat that has been infested with certain parasites?
O Parasite infestations are rare and disastrous.
Parasite infestations lead to economic loss.
Parasite infestations topple even lucrative farms.
Parasite infestations are easily prevented.
Answer:
Parasite infestations lead to economic loss
Explanation:
Parasites are organisms that live on or in another organism called the 'host', obtaining their food or some other benefit (e.g., a suitable habitat/environment) from this host. Most parasites are known to affect their hosts by invading their organ systems, thereby producing parasitic infestations. In livestock, parasitic infestations can produce substantial losses of productivity. Some of the most important factors associated with parasitic infestations include, among others, poor hygienic conditions, contaminated water, unmanaged livestock waste, etc.
The correct answer is Parasite infestations lead to economic loss.
The term "parasite" refers to an organism that lives on or in another organism, or "host," and depends on it for food or some other advantage (such as a suitable habitat or environment). The majority of parasites are known to infest their hosts' organ systems and negatively impact them, resulting in parasitic infestations. Infestations of parasites in animals can result in significant productivity losses. Poor hygienic conditions, unclean water, uncontrolled livestock waste, etc. are some of the most significant causes linked to parasite infestations.

Toward an Artificial Cell Scientists have recently constructed an artificial ribosome in vitro from purified ribosomal proteins and rRNAs. (Some of the following questions may require sleuthing in earlier chapters to answer.) What types of intermolecular forces do you think are holding the individual proteins and rRNAs together in this macromolecular complex
Answer:
RNAs and proteins can bind via electrostatic interactions, hydrophobic interactions, Hydrogen bonding interactions and base stacking interactions
Explanation:
Proteins bind to nucleic acids (i.e., both DNA and RNA) through different types of interactions:
- electrostatic interactions, also known as van der Waals interactions, refer to attractive/repulsive interactions between molecules depending on their electric charges.
- hydrophobic interactions, i.e., interactions between nonpolar molecules and water molecules
- Hydrogen bonding interactions resulting from the interaction between a hydrogen (H) atom that bind to an electronegative atom (e.g., N, O, F, etc), and another electronegative atom.
- base stacking interactions that result from the arrangement of RNA nucleotides
In this case, it is also important to highlight that the interaction will depend on the specific tertiary structure of ribosomal proteins and ribosomal RNAs (rRNAs).

Answer:
"Anything that looks like a snake should produce the instinctive fear response," Slobodchikoff said. “Cucumbers are shaped more like snakes, with their curving sides, than ears of corn or eggplants, so they produce a greater response."
But don't go trying to prank your cat with cucumber-shaped objects just yet. Scaring cats can have long-term effects on their mental health.
"Anytime you scare an animal, you risk inflicting psychological damage, so that the animal will be afraid not only of cucumbers,” Slobchikoff said, “but also the surroundings in which the cucumber was presented to the animal.”

A basketball player jumps straight up to dunk a basketball. The basketball player's speed increases as she returns to the
ground. What is true about the forces acting on the basketball player?
A. The upward force is greater than the downward force.
B. The downward force is greater than the upward force
C. The rightward force is greater than the leftward force.
D. The leftward force is greater than the rightward force.
Answer:
The downward force is greater than the upward force.
Explanation:
The remaining time is spent in the top of the jump (the top 25% of the jump). In other words, half the jump time is spent in the highest 25% of the jump (the top part of the arc). This explains why a basketball player appears to "hang" during the jump.
Select all that are true regarding ATP cycling
A. ATP is formed from ADP and phosphate
B. Energy for ATP synthesis comes from the oxidation of glucose and other fuel molecules
C. ATP hydrolysis is an endergonic reaction
D. Oxidation of ATP can be used for performing endergonic reactions in the cell
Answer:
A, B and D are correct
Explanation:
Adenosine diphosphate (ADP) can form a bond with a phosphate group to form Adenosine triphosphate (ATP), which is the most abundant energy carrier molecule in cells. An endergonic reaction is a chemical reaction where there is a net input of energy, while an exergonic reaction generates energy. ATP hydrolysis releases energy (conversely to ATP synthesis that requires an input of free energy), and therefore ATP hydrolysis is an exergonic reaction. ATP hydrolysis releases around 7.3 kilocalories per mole. In a coupled reaction, the energy released by ATP hydrolysis is used by the cell to carry out endergonic reactions in an exergonic manner (e.g., glucose phosphorylation, which is an energetically unfavorable reaction).
