please someone do this, i hate biology :(
Answer:
C - Natural selection is causing larger bird beaks.
E - Because the seed hardness has increased the birds need bigger beaks to crack them.
R - This means the birds with larger beaks are not able to crack the seeds, this causes starvation and the birds that have small beaks die as a result. However, birds with larger beaks are able to crack the seeds and eat. Those birds can then reproduce and produce more birds with larger beaks. So the population of large bird beaks has increased, but the population of small bird beaks has decreased.

Imagine that the cell is exposed to some kind of stressor such as extremes of temperature, exposure to toxins, or mechanical damage. The chain reactions will be
Disruption or the formation of cell membrane blebsAlteration of protein synthesis and accumulation of altered proteins in the ERAlteration of the chromatin of the chromosomes inside the nucleus and DNA damageAlteration of the permeability of organelles such as mitochondria with consequent alterations in metabolismDecrease in ATP levels and increase in cytoplasmic calcium levelThe combination of all this can lead the cell to death but it can respond in various ways:
the cell can decrease protein synthesis and induce the transcription of specific stress-sensitive chromosomal genes that correct altered proteinsIt can respond to DNA damage by stopping replication and trying to repair it If it cannot survive it can commit suifcide so as not to harm other cellsExplain the difference between sexual reproduction and asexual reproduction. Explain either an advantage or disadvantage for
each.
In asexual reproduction, reproductive organs aren't used but they're used.
advantage of sexual- A lot of genetic variation. since they have DNA of two parents. they can survive more and adapt more.
disadvantage of asexual- diversity is limited. Since the organism only gets the DNA of one parent, they wouldn't be able to really survive if something happened.They would easily be extinct.
Sorry I can't really cone up with better words but I hope you get the idea. it all comes down to natural selection really if you've learned about it. Hope it helped!!!

In patients infected with nonresistant strains of the tuberculosis bacterium, antibiotics can relieve symptoms in a few weeks. However, it takes much longer to halt the infection, and patients may discontinue treatment while bacteria are still present. How could this result in the evolution of drug-resistant pathogens?
The bacteria are still present and may obtain antibiotic resistance to spread to other species by horizontal gene transfer.
Antibiotics have become diluted and weak because of a limited supply.
Bacteria have purposefully directed their immune system to resist the effect of the antibiotic.
Resistant bacteria are polyploidy and can resist the antibiotic, a trait that is passed on to their offspring.
Answer:
The bacteria are still present and may obtain antibiotic resistance to spread to other species by horizontal gene transfer.

When a new viral infection appears in a population,scientists usually try to develop a vaccine against the virus. Which substances would most likely be contained in the new vaccin
Answer:
Antigen, stabilizers, surfactants, diluents, preservatives
Explanation:
Antigen: This is part of the protein structure virus or part of its genetic material. These parts are active. But sometimes, the inactivated form of the virus is also included in the vaccine. Stabilizers: Avoid other chemical reactions occurring in the interior of the vaccine. Surfactants: They prevent the occurrence of sedimentation and agglutination of the elements inside the vaccine. Diluent: Used to dilute the vaccine in an appropriate concentration before being used. Preservatives: As the word says, preservatives avoid any possible contamination of the vaccine. These elements´ use depends on the doses prepared. If it is only for one-person use, then they are not needed. But if the doses are to be used by more than one person, they need preservatives because once the vaccine is opened it is vulnerable to contamination.IS MY FINAL EXAM I NEED HELP!

Explanation:
Genetically engineered foods (GE foods), or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering. Genetic engineering techniques allow for the introduction of new traits as well as greater control over traits when compared to previous methods, such as selective breeding and mutation breeding.[
Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its unsuccessful Flavr Savr delayed-ripening tomato. Most food modifications have primarily focused on cash crops in high demand by farmers such as soybean, corn, canola, and cotton. Genetically modified crops have been engineered for resistance to pathogens and herbicides and for better nutrient profiles. GM livestock has been developed, although, as of 2015, none were on the market.

1. Why does the moon go through Phases?
I
2. Why do we experience solar and lunar eclipses?
3. What is the underlying reason the Earth goes through
Seasons?
Explanation:
1.The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. The Moon spends the extra 2.2 days "catching up" because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth.
2.
An eclipse is the result of the total or partial masking of a celestial body by another along an observer's line of sight. Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth's shadow hides the Moon from view.Lunar and solar eclipses occur with about equal frequency. Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar eclipse.
3.Why Do We have Seasons?
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected. Since the tilt of the axis is 23 1/2 degrees, the North Pole never points directly at the Sun, but on the summer solstice it points as close as it can, and on the winter solstice as far as it can.
Why Do the Seasons Change on Earth?
Two things cause the seasons to change. First, the Earth moves around the Sun. Second, the Earth has a tilted axis of rotation.
The Earth spins around an axis. This imaginary line extends from the South Pole to the North Pole. But the Earth’s axis is not vertical. It’s actually tilted at an angle of 23.5°. The planet is always tilted in the same direction as it orbits the Sun.

Two primary agents of cellular communication are
Two primary agents of cellular communication are hormones and chemicals produced by nerve cells.
What are the principles of cellular communications?
Cellular communication is a stepwise process that affects the generation of an extrinsic signal, detection of the signal by a receptor, transduction of the signal by intracellular signalling molecules and cellular response. When the extrinsic signal is removed, cellular communication processes cease.
Thus, hormones and chemicals are two primary agents of cellular communication.

Mendel is considered the Father of Genetics. His famous pea plant experiments helped to formulate several laws in genetics that have
stood the test of time with very little modification. Match each law or term with the correct description/definition.
Answer:
The Principles Of Mendel's Genetics
1.Law of Segregation
2.Law of independent assortment
3.Law of dominance
4.Recessive Allele
5.Co-dominance
6.Incomplete Dominance
Explanation:
The Law of Segregation, often known as Mendel's First Law, stipulates that two alleles for a trait segregate during the production of gametes, resulting in each gamete having just one copy of each allele.
What is an explanation of the concept ?This concept explains why a cross between two animals with dissimilar features, such as flower colour, can occasionally result in an intermediate phenotype in the progeny.
Mendel's Second Law, or the Law of Independent Assortment, states that the inheritance of one feature is not reliant upon the inheritance of another trait. This concept explains why a cross between two animals with dissimilar features can result in offspring that exhibits every feasible combination of the two qualities.
Mendel's research with pea plants was groundbreaking in thea branch of genetics. His thorough research and tests resulted in the development of two laws that are now the cornerstones of genetics. According to the Law of Segregation, two alleles for a trait separate from one another throughout the development of gametes, leaving just one allele per trait in each gamete.
This concept explains why a cross between two animals with dissimilar features, such as flower colour, can occasionally result in an intermediate phenotype in the progeny.
According to the Law of Independent Assortment, one trait's inheritance is not correlated with that of another. This law explains how a cross between two creatures with distinct features can result in offspring that can display any combination of the traits.

In guinea pigs, short fur (S) is dominant to long fur (s). Two heterozygous guinea pigs
(Ss) mate. Complete the Punnett square and then list the percentages of the
expected genotypes for their offspring.
Explanation:
A way I like to remember heterozygous is by remembering that the other word for heterozygous because brainly wont let me say it apparently. The same gender liking each other, so (word) is same, hetero is different.
each square would have 25% each because 100%÷4=25.
Dominant one is like mixing black and blue together,the black is gonna give a dark effect to blue so black is dominant.
Blue is recessive.
The percentage of the Ss is 75% while the percentage of the ss is only 25%.
Performing a crossGiven that we have the genotypes of the both parents as Ss. The Ss imples that the gene for short fur is dominant over the gene for long fur.
Now, when we perform te cross for the first generation, we will discover that we have the offspring; Ss, Ss, Ss and ss. The percentage of the Ss is 75% while the percentage of the ss is only 25%.
