Answer:
The proportion of plants with deep flowers in future generations will decrease and will be very low.
Explanation:
To analyze this, we need to keep in mind the pollination process and the following general ideas:
Bees with long tongues can obtain nectar from deep flowers by visiting the top of them and extending their tongues to their bottom.During their visit to the flowers and their search for nectar, long-tongued bees transport pollen from flower to flower, favoring pollination.Bees with short tongues can obtain nectar from deep flowers by drilling holes in their base without visiting their tops.Short-tongued bees do not need to access the nectar by the top of the flower. They do not get in contact with stamens, so they do not play a pollinator roll. In a particular environment, bees with short tongues replace bees with long tongues.In this particular environment, long-tongued bees used to visit plants with deep flowers to get their nectar. They used to get in contact with mature stamens and carry the pollen on their bodies to the next flower. During this process, long-tongued bees were able to ensure pollination and helped to keep a high reproductive rate of plants with deep flowers.
When shorted-tongue bees arrived at this environment, they were able to replace long-tongued bees. They also looked for the nectar of deep flowers, but instead of visiting them from the top, they were adapted to obtain nectar by drilling holes in the flower base. In this way, they missed the contact with mature stamens and pollen.
Long-tongued bees disappear, and short-tongued bees did not play a role in the pollination process of deep flowers, then the reproductive rate of these vegetable species probably started to decline.
Probably, with time, the proportion of plants with deep flowers in an environment dominated by short-tongued bees will be very low.
The proportion of plants with deep flowers in future generations will decline if bees with short tongues replace bees with long tongues.
What do you mean by environment?Anything which is present in the surrounding of an organism is called its environment. It may consist of Biotic and abiotic factors.
Bees with short tongues are able to obtain nectar from deep flowers by drilling holes in the base of the flower without visiting the top of the flower. In this way, such bees are not in contact with mature stamen and pollen. Therefore, they will not play an effective role in pollination. And if such bees are replaced with long tongues bees, there will never be a deep flower obtained. Deep flowers are obtained by long-tongued bees because they take nectar from the top side and with it they also take mature stamen and pollen to perform successful pollination.
Therefore, the proportion of plants with deep flowers in future generations will decline, if bees with short tongues replace bees with long tongues.

19. Which of the following is the best strategy to control wheat rust?
O A. Invasive insect species to attack rust
B. Fungicides to treat affected crops and planting rust-resistant varieties
C. Citrus greening to prevent the spread of rust
O D. Insulation using green roofs to limit rust
Answer:
B. Fungicides to treat affected crops and planting rust-resistant varieties
Explanation:
Leaf rust is a disease caused by the fungus Puccinia triticina which affects leaves, stems and grains in wheat and related cereals (i.e., barley and rye). This disease is known to affect crops in moist conditions. Leaf rust disease is spread through fungi spores from infected wheat plants to healthy plants. Recently, leaf rust-resistant varieties have been developed by crop improvement programs aimed at introducing leaf rust-resistant (lr) genes involved in resistance against this important crop disease. Moreover, there are different types of fungicides (e.g., Prothioconazole and Tebuconazole) used for chemical control of this disease.

The two structures most likely to be observed by the scientist when looking at a type of bacteria under the microscope are cell wall and vacuole (option C).
Explanation:
Bacteria are prokaryotic organisms that lack a nucleus, most of the organelles, and whose DNA is dispersed in the cytoplasm. Some types of bacteria have a plasma membrane surrounded by a cell wall, and may be equipped with vacuoles to perform their functions.
It is very likely that two structures that are most likely to be differentiated when a type of bacteria is observed under the microscope are the cell wall and the vacuole, according with information above.
The other options are not correct because:
A and D. Bacteria lack a nucleus.
A and B. Bacterial DNA is dispersed in the cytoplasm and is very difficult to observe under the microscope.

Explanation:
It was the big day; Lance had been training for months in anticipation of the annual “Dasher Twenty-Six-Two.” As he laced up his sneakers, he thought back to the endless grind of aerobic training he had accomplished. Hour after hour of lung-burning, quad frying jogging on pavement and dirty. He was ready mentally and physically, plus he had a secret weapon ready to go. Lance had been experimenting in the use of a thick, sugar saturated gel-nutrition to supplement his running. He anticipated finishing just before the three-hour mark and he planned to eat his special goo around hour two for a much-needed energy boost. The goo solution was a mixture of maltose, sucrose, and glucose, as well as some salt. Water would be available on the course every few miles and with his nutrition plan set he found his way to the line. *BOOM*
The start gun leaked smoke as wave after wave of runner set off. Miles started flowing by… five miles feeling good… Mile thirteen halfway there! Just as the two-hour mark was upon him, Lance pulled the gel from his pocket and slurped the gooey syrup down. Mile fifteen Phew, heavy legs… Mile eighteen Legs are burning but I got it… then came a hit of fatigue.
He had read about this before. The dreaded bonk. Bonking was said to be the final drips of glycogen being removed from the muscle’s cells, with an accompanying burn suggesting rapid production of lactate. It also meant he had spent the last two hours less aerobic than he thought. Making it to mile twenty-two, Lance noticed his heart rate ten-beats over his planned pace. His breath was getting harsher, his legs getting weaker. The mile twenty-four marker went by and he was down to nearly a walk, lips dry and stomach lurching. The last half mile was a blur as Lance crossed the line his raised arms quickly fell, and so did he, right into a chair near the finish line.
Discuss the necessity of Lance’s training to prepare for his ability to fuel a marathon with specific reference to the major organ systems involved and their purpose. Identify the needed reactants and excreted products Lance utilized during his ongoing respiring, with specific reference to where each is created or used. Finally, predict the influence of his experimental goo and suggest advantages and disadvantages to its use, as well as better use with reference to time and impact on the ability to enter and circulate to where it would be needed

hypothesis on what is the effect of the genes of the parental mice on the fur color of the offspring mice? use "If...then...format
Answer:
If the GENES of the parental mice encodes for a black fur, THEN the FUR COLOR of one of the offspring mice will be black.
Explanation:
Hypothesis is one of the steps used in the scientific method. It is a testable explanation of a given question or observation. Hypothesis in an experiment must be subjected to testing via experimentation in order to determine whether to reject it or not.
Hypothesis is usually constructed in the IF, THEN format. It tells us how the independent variable (cause) affects the dependent variable (outcome). In this case, a question is asked this: "what is the effect of the genes of the parental mice on the fur color of the offspring mice?"
A possible hypothesis will be: If the GENES of the parental mice encodes a black fur, THEN the FUR COLOR of one of the offspring mice will be black.
Answer:
A. If either parent mouse passes a dominant allele, the offspring will have black fur.
Explanation:
Either option is correct because it didn't show any green check. It determines on what hypothesis you wrote. I chose A because it relates to my statement. <33

gasoline-powered vehicles, each with only one occupant?
A. It conserves more fossil fuels.
B. It uses the same amount of fuel per person.
C. It uses more expensive fuel per person.
D. It uses more fossil fuels per person
Answer: A. It conserves more fossil fuels
Explanation:
This approach saves more fossil fuels than using lots of gasoline-powered cars, each with just one occupant. So, the correct option is A.
What are Fossil fuels?A fossil fuel is a hydrocarbon-containing substance that is recovered and used as fuel that naturally forms in the Earth's crust from the remains of dead organisms and plants. Fossil fuels include coal, oil, and natural gas. Fossil fuels can be burned to produce energy, drive engines, or provide heat for immediate use.
A general name encompassing non-renewable energy sources such crude oil, petroleum products, natural gas, derived gas, coal, coal products, and non-renewable wastes is "fossil fuel." These fuels are made from ancient geologically-dated plants and animals (for example, millions of years ago). Compared to using many single-occupant gasoline-powered cars, the method conserves more fossil fuels.
Therefore, the correct option is A.

In which area of the cell does the interaction between codon and anti codon occur?
Answer:
This occurs at the 3′ end position which sits on an mRNA, while a distinct tRNA anticodon triplet sequence matches a three complementary base pair mRNA codon sequence to guide appropriate amino acid into place at a ribosome activation site to form a polypeptide or protein.
The interaction between codon and anti-codon is occurs at the 3′ end position which sits on an mRNA.
What are the functions of mRNA?Messenger ribonucleic acid is a single-stranded molecule of RNA that corresponds to the genetic sequence of a gene, and is read by a ribosome in the process of synthesizing a protein.
The role of mRNA is to carry protein information from the DNA in a cell's nucleus to the cell's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates each three-base codon into its corresponding amino acid.
Found in all cells, messenger ribonucleic acid, or mRNA, is a single-stranded molecule. It is responsible for transferring genetic information from DNA, found in the nucleus of the cell, to ribosomes floating in the cell's cytoplasm.
