Explanation:
A species of elm has winged-seeds. How would biologists explain how a species of elm with winged-seeds evolved from an ancestral elm species without winged-seeds
Answer:
In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species
Explanation:
A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.

Flagellants atoning for sinsGovernments quarantining all those who fell illShutting down tradePrayingWhat is a plague?A plague is a highly infectious and often fatal disease caused by the bacterium Yersinia pestis. The most infamous outbreak of the plague occurred in the 14th century in Europe, killing an estimated 25 million people, or one-third of the population. The disease is typically spread through the bite of an infected flea, although it can also be transmitted through contact with infected animals or humans.
There are three forms of the plague: bubonic, septicemic, and pneumonic. Bubonic plague is the most common form and causes swollen lymph nodes, fever, chills, and fatigue. Septicemic plague affects the bloodstream and can cause fever, chills, abdominal pain, and vomiting. Pneumonic plague affects the lungs and can cause fever, cough, chest pain, and difficulty breathing.
Today, the plague is rare but still exists in some parts of the world, including Africa and Asia. Early diagnosis and treatment with antibiotics are essential for successful treatment of the disease.

Chloroplasts contain chlorophyll and carotenoids. Chlorophyll directly absorbs light for use in photosynthesis.
Carotenoids absorb light and transfer the energy from light to chlorophyll. The efficiency of photosynthesis varies with
the wavelengths of the light that illuminates the chloroplasts. In an experiment to study the relationship between the
incoming light wavelengths and the chemical reactions of photosynthesis using a species of green algae, a researcher
labeled the COt2 supply to the algae with 14C, and the H20 with 180.
Which of the following results is expected?
O More 14C is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red
light.
O More 180 is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red

Answer: Answer below, hope this helps! :D
Explanation:
A conjugated protein is a protein that functions in interaction with other (non-polypeptide) chemical groups attached by covalent bonding or weak interactions. ... The non-amino part of a conjugated protein is usually called its prosthetic group. Most prosthetic groups are formed from vitamins. Hemoglobin is a protein having a globular structure. Based on its structural properties, hemoglobin can be divided into two parts; a protein part and a heme group. The structure of the protein part can be studied at four levels; primary structure, secondary structure, tertiary structure, and quaternary structure.

At what points in the progression from gene to protein do these methods act (i.e., what processes do they prevent)
Answer:
Genes are translated, transcribed and after these two steps, the formation of a protein takes place.
DNA is translated, that is, read, in the form of codes and thanks to the machinery of intracellular transcriptases, after this an RNA is encoded that will be made with the assembly of amino acids that together will form proteins.
Proteins can be structural or functional.
Explanation:
There are different methods to intervene in these processes, it can be by means of macromolecules, drugs and also by microbiological factors, that is, by microorganisms such as viruses that take advantage of the human transcription machinery to replicate.
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. This behavior does not kill the flower. In a particular environment, bees with short tongues replace bees with long tongues. Predict the effect on the proportion of plants with deep flowers in future generations. Justify your prediction.
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.

How does sexual reproduction increase the variance of traits in a population?
Please also describe how actin-binding sites are made available for cross-bridging with myosin heads during contraction.
Answer: The calcium ion binds to troponin, and this slides the tropomyosin rods away from the binding sites.
Explanation:
Contraction and relaxation of muscle cells brings about movements of the body. The contractile myofilament called sarcomeres are bounded at each end by a dense stripe called the Z - line, to which the myosin fibres are attached, and lying in the middle of the sarcomere are the actin filaments, overlapping with the myosin.
When action potential spreads from the nerve along the sarcolemma (muscle cell membrane), it penetrates deep into the muscle cell through the sarcoplasm (cytoplasm of muscle cell), and releases CALCIUM from the intracellular stores.CALCIUM triggers the binding of myosin to the actin filament next to it forming CROSS BRIDGES.
For this to occur, ACTIN BINDING SITE has to be made available. TROPOMYOSIN is a protein that winds around the chains of the actin filament and covers the myosin-binding sites to prevent actin from binding to myosin. The first step in the process of contraction is for calcium ions to bind to troponin so that tropomyosin can slide away from the binding sites on the actin strands.
