The hottest recorded temperature in history occurred in Death Valley, California, July 10, 1913. The temperature was recorded at 134°F. Convert this temperature to Celsius and Kelvin.

Answer:

equation is 2n = 46

Explanation:

humans have 2 sets of 23 chromosomes

Two full sets of chromosomes make up a diploid cell. Humans mostly have diploid cells, which have 23 pairs of chromosomes each, for a total of 46 chromosomes.

There are 22 pairs of autosomes and two sex chromosomes in this. The person received one copy of each pair of chromosomes from their mother and the other copy from their father.

A "diploid cell" is one that has two copies of each chromosome; human somatic cells are diploid and have 46 chromosomes, 22 pairs of autosomes, and a pair of sex chromosomes.

Histones, which function as packing proteins for the majority of eukaryotic chromosomes, join forces with chaperone proteins to attach to and compress the DNA molecule, maintaining the integrity of the molecule.

Therefore, diploid cells, have 23 pairs of chromosomes each, for a total of 46 chromosomes.

Explanation:

The increase in CO2 and CH4 levels in the Earth's atmosphere enhances the greenhouse effect, causing more heat to be trapped and redirected back to the surface. This results in a rise in surface temperatures and various impacts on the climate system.

When the amounts of CO2 (carbon dioxide) and CH4 (methane) in the Earth system increase, it leads to an increase in temperatures due to the greenhouse effect. The atmosphere plays a crucial role in this process.

Both CO2 and CH4 are greenhouse gases, which means they can trap heat in the atmosphere. When sunlight reaches the Earth's surface, it radiates back as infrared (heat) energy. Normally, some of this heat escapes into space, maintaining a balance. However, the increased levels of CO2 and CH4 act as a barrier, trapping more heat and redirecting it back to the Earth's surface.

CO2 is particularly important in this process. It is released primarily through the burning of fossil fuels, deforestation, and other human activities. The rising CO2 levels from these activities enhance the greenhouse effect. Similarly, CH4, which is emitted by natural sources like wetlands and human activities such as livestock farming and fossil fuel extraction, also contributes to the greenhouse effect.

As more heat is trapped, the surface temperature of the Earth increases. This rise in temperature affects the climate system, leading to various consequences such as global warming, altered weather patterns, and sea level rise.

Blue whales are the largest animals on Earth. They can measure up to 110 feet long and weigh as much as 400,000 pounds. Blue whale babies are born big. They can weigh as much as 6,000 pounds at birth. They grow for one full year to reach their adult size.

Blue whales live in the ocean. They swim fast, which helps them catch food. Blue whales must eat up to 8,000 pounds of food each day. They eat tiny fish called krill. To eat, the whale opens its mouth and lets the krill swim in.

Once the krill are inside, the whale begins to close its mouth. It does not close the mouth the whole way, though. The whale shows its baleen. Baleen are long, strong hairs that act like teeth. The baleen allow the water to flow out. The baleen keep the krill in. The whale can then eat the fish.

The two methods that allow fish to maintain water balance in saltwater are pumping out salt through the gills and absorbing water into the body by osmosis.

In saltwater, the concentration of dissolved salts is higher in the surrounding water than in the fish's body cells. To maintain water balance, fish have developed two main methods:

1. Pumping out salt through the gills: Fish possess specialized cells in their gills that actively pump out excess salts from their bodies. This process helps maintain a lower salt concentration within the fish's body, preventing dehydration and maintaining water balance.

2. Absorbing water into the body by osmosis: Osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane. Fish have a protective layer of skin that allows water to be absorbed into their bodies while preventing the entry of excessive salts.

By absorbing water through their skin, fish replenish the water lost to the surrounding saltwater, helping to maintain their internal water balance.

These two mechanisms work together to enable fish to survive in saltwater environments. By actively pumping out salts and absorbing water, fish can regulate their internal salt concentration and prevent dehydration, ensuring their overall water balance is maintained.

Half will have red flowers and half will have white flowers (option c).

In camellia plants, flower color is controlled by a single gene with codominant alleles. In this case, one parent plant has red flowers (R), while the other parent plant has white flowers (WW).

When two organisms with codominant alleles are crossed, both alleles are expressed equally in the offspring. Therefore, in this cross, the offspring will inherit one allele for red flowers (R) from the red-flowered parent and one allele for white flowers (W) from the white-flowered parent.

The possible combinations of alleles that the offspring can inherit are RW and RW.

When the alleles RW and RW combine, the resulting genotypes are RR (red-flowered) and RW (pink-flowered). However, since the allele for white flowers (W) is recessive to the allele for red flowers (R), the plants with the RW genotype will exhibit the dominant red flower phenotype.

Therefore, half of the offspring will have the RR genotype and display red flowers, while the other half will have the RW genotype and also display red flowers. None of the offspring will have the WW genotype, so there won't be any white flowers.

Hence, the expected phenotypes of the offspring of this cross are that half will have red flowers and half will have white flowers. Thus, the correct option is c.

For lytic viruses, there is typically a latent period during the viral growth curve when the virus is not detected.

During this phase, the virus has entered the host cell and has begun to replicate its genetic material, but no mature virions have been produced yet. The duration of the latent period can vary depending on the virus and the host cell, and it can range from a few hours to several days.

After the latent period, the  lytic viruses enters a rapid growth phase, during which the number of virions produced increases rapidly. This phase is characterized by a steep increase in the viral titer, which can be measured using various methods such as plaque assays or quantitative PCR. The rapid growth phase is followed by a plateau phase, during which the number of virions produced levels off and reaches a maximum.

Finally, the viral growth curve enters a decline phase, during which the number of virions decreases as the host cells are destroyed and the infection is cleared. The duration of the decline phase can vary depending on the immune response of the host and the effectiveness of antiviral treatments, if any.

The author of the story below uses figurative language to reveal that the narrator feels unnoticed by Natalie (option D)

Figurative language deviates from the usual word order and meaning in order to convey a complex meaning, vivid writing, clarity, or an emotive comparison. By using a regular sentence, it refers to something without actually declaring it.

Figurative language, which is frequently used in both literature and everyday speech, is present in many phrases. Figurative language asks the reader or listener to consider the meaning of something (a "vehicle") in the context of other ideas, actions, or visuals (a "tenor").

Understanding figurative language is necessary to read the Management Discussion and Analysis (MD&A), where management may use a metaphor to clarify complex ideas or the direction the organization is taking.

The question is incomplete, it should be:

My sister Natalie wanted to grow up in seconds and not in years. I was left behind to catch up in real time. Only two years apart, I also felt decades away from her. Natalie wanted privacy, personal room, and mother’s pretty possessions at ten. I longed for her cuddles, which she only dispensed when she had upset me and was sorry. I loved my big sister with every ounce of my being though she felt weighed down by my displays of affection.

“When I was your age, your aunt Jen and I weren’t close,” our mother confessed. “Now, we can’t get enough of each other. Your grandparents are really old, and we share our worries and responsibilities, you know.”

I wasn’t ready to think about that—my beautiful mother being frail or my towering father using a cane. I suspected Natalie would be ahead in the care arrangements and that I would try to play catch-up. I wondered if I would always be just a shadow in Natalie’s life until the day I caught her sobbing in the hallway.

“You didn’t see anything,” Natalie said between sobs and rushed to her room, which she didn’t seal with a locked door.

Entering her neat room, which was a furniture catalog, was a privilege. The veneer of the green curtains added a layer of beauty to the windows. Except for crumbled tissues in the trashcan, nothing seemed unkempt. What had been bothering my perfect sister?

“What’s wrong?” I asked and sat on the edge of the bed to take up the smallest possible space. Then, I spotted a broken friendship bracelet by the night lamp. How could I have not noticed before? Carly hadn’t come over in months. Natalie wasn’t on the phone every free minute of Saturday and Sunday. I had been buried in books and band practice and failed to see my big sister’s loneliness. “Do you want to watch Zombie Cheer together? We don’t have to talk. We can just be…together.”

Natalie lunged at me to hold me tight and wailed until my hair was damp. I let her. Then, she dried her face with tissues and took me by the hand to the living room. Mother had already set up two big bowls of popcorn, which looked like heaps of comfort. Mother always knew everything.

On the conditions being really good this year for breeding:

1. The Hardy-Weinberg principle states that in a population in which mating is random, the frequency of alleles will remain constant from generation to generation. This means that if the frequency of the allele for poor vision is p and the frequency of the allele for good vision is q, then the frequency of each genotype will be:

AA = p²

Aa = 2pq

aa = q²

In this case, the frequency of poor vision is 0.35, so p = 0.35 and q = 0.65. This means that the frequency of each genotype will be:

AA = (0.35)² = 0.1225

Aa = 2(0.35)(0.65) = 0.4225

aa = (0.65)² = 0.4225

Therefore, we would expect 1,245 × 0.1225 = 153 young "potential" Biology instructors to have poor vision and 1,245 × 0.4225 = 525 to have good vision.

2. The allele for white coloring is recessive, so the only way for a mouse to be white is if it inherits two copies of the recessive allele. If the frequency of the white allele is q, then the frequency of white mice will be q². In this case, 35% of the mice are white, so q = 0.588. This means that the frequency of the white allele is 0.588 and the frequency of the non-white allele is 0.412.

The genotypic frequencies can be calculated using the Hardy-Weinberg principle:

AA = p² = (0.412)² = 0.169

Aa = 2pq = 2(0.412)(0.588) = 0.472

aa = q² = (0.588)² = 0.338

Therefore, 15% of the mice will be homozygous dominant (AA), 47% will be heterozygous (Aa), and 38% will be homozygous recessive (aa).

3. The ability to taste PTC is due to a single dominant allele "T". If the frequency of the T allele is p, then the frequency of the t allele is q = 1 - p. In this case, 150 of the 215 individuals could detect the bitter taste of PTC, which means that p = 0.702. This means that the frequency of the T allele is 0.702 and the frequency of the t allele is 0.298.

The genotypic frequencies can be calculated using the Hardy-Weinberg principle:

TT = p² = (0.702)² = 0.492

Tt = 2pq = 2(0.702)(0.298) = 0.392

tt = q² = (0.298)² = 0.088

Therefore, 49% of the individuals will be homozygous dominant (TT), 39% will be heterozygous (Tt), and 12% will be homozygous recessive (tt).
