Answers
Final answer:
Paleontologists Stephen Jay Gould and Niles Eldredge proposed the theory of punctuated equilibria, which describes the pattern of evolution as long periods of stability interrupted by brief periods of rapid change, explaining the fossil record's structure and the relative stability of species over time.
Explanation:
Gould and Eldredge proposed a new evolutionary theory known as punctuated equilibria. This theory suggests that instead of species evolving continuously over time, they remain stable for long periods, known as equilibrium, and undergo rapid evolution during relatively brief periods of ecological instability, leading to new species. These evolutionary bursts punctuate the long periods of stasis. Punctuated equilibria helps explain the patterns observed in the fossil record, including the presence of small anatomical gaps between closely related fossil forms. The theory underscores the stability of species over time, with adaptation occurring primarily during the formation of a new species, rather than as a constant process. While it incorporates genetic principles, punctuated equilibria is primarily a theory of macroevolution, focusing on the transitions between species in geological time.
The butterflies shown below all belong to the same species, but one of them has inherited a rare mutation for blue wings rather than orange wings. The butterflies feed on nectar from orange flowers, and their color acts as camouflage while they feed.
What will most likely happen to the butterfly with blue wings?
Answers
Their population will decrease while that of orange-winged butterflies will increase. Therefore the allelic frequency for blue colored wings will be eventually eliminated from the population.
This is because the blue-winged butterflies will be predated more because they are more conspicuous. Most will not produce before they are predated on hence reducing their numbers. The next generations will have more and more of orange-winged butterflies until the blue-winged butterflies no longer exist in the population.
Answer:
It will be less likely to survive because it will be more visible to predators.

under ideal conditions, bacteria have a generation time of about 20 minutes. Humans have a generation time of about 20 years. Which would you expect to evolve faster? Why?
Answers
Let me know if you need further explanation.
Bacteria would be expected to evolve faster than humans due to their significantly shorter generation time. This allows for frequent genetic recombination and mutation, resulting in rapid adaptation to environmental changes.
Explanation:Under ideal conditions, bacteria, such as Escherichia coli, can have a generation time as short as 20 minutes due to binary fission. This rapid reproduction, coupled with mechanisms of genetic recombination and high rates of mutation, results in the rapid evolution of bacteria. They can respond to environmental changes, such as the introduction of an antibiotic, very swiftly.
On the other hand, humans, as eukaryotic organisms, have a typical generation time of about 20 years. The significantly longer generation time in humans slows the pace of evolution considerably when compared to bacteria.
Therefore, under ideal conditions, we would expect bacteria to evolve faster than humans due to their shorter generation time, allowing for more frequent genetic recombination and mutation.

What is a spring tide abs would a spring tide occur
Answers
A spring tide occurs during the new and full moon phases when the Sun and Moon align, leading to the highest and lowest tides of the month. This contrast creates the greatest tidal range.
A spring tide occurs when the gravitational forces of the Sun and Moon align either on the same side of Earth or on opposite sides.
This alignment happens during the new moon and full moon phases, where the combined gravitational pull results in the highest high tides and the lowest low tides of the month, leading to the greatest tidal range.Conversely, a neap tide occurs when the Sun and Moon are at right angles to each other, during the first and third quarters of the moon. During this period, their gravitational forces partially offset each other, leading to the smallest tidal ranges of the month.Which organelles store food and other materials needed by the cell?

Answers
Ribosome makes protein for the cell
Chloroplasts create food for only the plant cell( animal cells does not have chloroplast)
Mitochondria makes food for the animal cell? This one I’m not sure of.
The vacuoles are the organelles that store food and other materials required by the cell. They maintain pressure within the cell and support its structure besides storing substances. Other organelles have differing functions such as protein production, photosynthesis, and energy production.
Explanation:The organelles that store food and other materials needed by the cell are the vacuoles. Located mainly in plant cells, vacuoles are large, fluid-filled organelles that store substances like water, nutrients, or waste products. In addition to storing substances, they also contribute to many other functions within the cell such as maintaining pressure within the cell which helps the plant cell keep its structure.
It's worth noting that other organelles like ribosomes, chloroplasts, and mitochondria also play significant roles within cells. Ribosomes produce proteins, chloroplasts are involved in photosynthesis in plant cells, and mitochondria are responsible for producing energy in the cell through the process of cellular respiration.

Answers
Where sexual selection is based on male competitiveness, bright-colored males are expected to be seen.
What distinguishes sexual selection?Sexual selection theory holds that the emergence of some noticeable physical qualities in animals, such as pronounced colour, increased size, or spectacular adornments, may provide the possessors of these traits more success in attracting mates.
Because the number of gene copies in the next generation is also dependent on relative mating success, the strength of sexual selection is proportional to the relative increase in the number of offspring surviving to reproduce (Sn) and the relative number of mates a male with that character obtains.

Answers
Potential energy is converted into kinetic energy. Before the yo-yo begins its fall it has stored energy due to its position. At the top it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy. At the bottom its potential energy has been converted into kinetic energy so that it now has its maximum kinetic energy.
A waterfall has both potential and kinetic energy. The water at the top of Bridal Veil Falls has stored potential energy. When the water begins to fall, its potential energy is changed into kinetic energy. This change in energy also happens at Niagara Falls where it is used to provide electricity from the transformation of mechanical and electromagnetic energy to parts of the northeastern United States.

What happens to the recessive allele in a heterozygous offspring
Answers
In a heterozygous offspring, the recessive allele becomes latent. It can be passed on to future generations and may show up in the phenotype if an offspring is homozygous recessive.
Explanation:In a heterozygous offspring, the recessive allele essentially becomes 'latent', meaning it is present but not expressed in the phenotype. This occurs due to Mendel's law of dominance which states that in a heterozygote, the dominant allele masks the effect of the recessive allele. The recessive allele will only be observable in offspring that are homozygous recessive in nature.
When parents with contrasting dominant and recessive traits reproduce, their offspring will mostly be heterozygous but will express the dominant trait in their phenotype. However, if these heterozygous offspring reproduce, the recessive trait can reappear in the next generation. This happens due to random segregation during formation of gametes where each allele from a pair has an equal chance of being passed on to the offspring.
The recessive trait can appear in the third generation with a 25% probability when heterozygous parents reproduce. This is because there's a 1 in 4 chance of getting a homozygous recessive offspring - that is, an offspring that inherits the recessive allele from both parents.

Antigens trigger the production of antibodies and antibodies destroy pathogens
Antigens are foreign substances that trigger the production of antibodies in the body. Antibodies, produced by the immune system, recognize and neutralize these antigens, thus helping to protect the body from infections.
Explanation:The correct option is: Antigens trigger the production of antibodies; antibodies destroy pathogens. Antigens are foreign substances (usually proteins) that invade the body, like bacteria, viruses, or allergens. When your body recognizes these foreign substances, it produces antibodies. Antibodies are proteins produced by the immune system that can identify and neutralize the antigens. In other words, antigens stimulate your immune system to produce antibodies against them, and then the antibodies bind to the antigens and eliminate them, protecting the body from infections.

b. In the face of famine, the marine iguanas have adapted by having the ability to shrink their body size. They are able to grow back to their original size once the food is supply increases.
4. Explain how these observations influenced his theory of evolution?
These observations led Darwin to believe that if a certain trait is more advantageous in a specific environment, then the carriers of that trait are more likely to survive into adulthood and to generate offspring than those who do not have that trait. Eventually, the advantageous traits for a species will proliferate. Darwin later called this as "survival of the fittest".

Beth learned in her science class that white blood cells in the human body capture harmful material by engulfing them. Then they digest them using enzymes, thus protecting the body from infection. Which eukaryote has a similar mode of nutrition?
Answers
Answer:
The Answer Is C): Amoeba
Explanation:
Plz Mark Me As Brainliest
Amoebas are eukaryotic microorganisms that have a similar mode of nutrition to the process described for white blood cells. They capture and engulf food particles, such as bacteria or small organic particles, through a process called phagocytosis.
After engulfing the food particle, amoebas form a food vacuole around it. Within the food vacuole, enzymes are secreted to digest the captured material, allowing the amoeba to obtain nutrients and energy from the ingested material.
This process of engulfing and digesting food is known as phagocytic nutrition and is a characteristic feature of certain eukaryotic organisms like amoebas.
