Answer:
Friction: A force that opposes the motion of objects that touch as they move past each other. Friction acts at the surface where objects are in contact.
Explanation:
The force that acts against your pushing force is called friction. is a force that resists the motion between two surfaces in contact. When you try to slide two surfaces across each other, the force of friction resists the sliding motion.
hello i need help on my last question this question is a bonus point to anyone who answer it
Answer:
A
Explanation:
A: Venus rotates far more slowly than Earth
Look at the column that says Period of Rotation.
Venus has a rotation period of 243 days.
Earth has a rotation period of about 24 hours.
243 days is much longer than 24 hours, so this is true.
B: Venus's year is longer than Earth's.
The year is also another way to say Period of Revolution.
Venus's is about 224 days.
Earth's is about 365 days.
Venus's is actually shorter, so this is false.
C: Mercury is approximately twice the size of Earth.
Let's look at the Equatorial Diameter column.
Mercury's is 4,880 km.
Earth's is 12,756 km.
Mercury's is much smaller than Earth's, so this is false.
D: All of the above.
Since B and C are both not true, this is incorrect.
Therefore, the correct answer is A: Venus rotates far more slowly than Earth.
which of the following describes an interaction where an organism of one species benefits and an organisms of a different species is not significantly affected?
You observe a population of Island Sparrows for which the phenotype of crown color varies from yellow to white. You perform two experiments. Experiment 1 shows that this variation in the phenotype affects mating success, so that birds with yellow crown colors have more offspring. Experiment 2 shows that this variation in phenotype is determined fully by the diet of the birds and not genetics. Can crown color evolve via natural selection in this population of Island Sparrows?
Answer:
Yes, the color of the crown evolves by the process of natural selection.
Explanation:
Based on experiment 1 mentioned in the question, it is clear that the sparrows with the yellow crown are demonstrating reproductive success, and based on experiment 2, it is demonstrated that the origination of crown color is solely dependent upon the diet consumed by the sparrows, not on the genes.
The yellow crown sparrows exhibit enhanced skills in locating food, finding food or prey is dependent upon the factors like skills of hunting, vision, the musculature of the body, and other things, and all these are partially or completely determined by genetics. This yellow crown sparrow will further pass on their genes to their offspring, which will further provide them good skills of locating food, and thus, will obtain the diet needed for proper growth. These offspring will further pass on the traits to the future generations, and so on.
On the other hand, the sparrows exhibiting white crown seem to be less efficient in locating their food, and they are also generating fewer offspring that exhibit the same lack of food locating skills like their parents. Due to less tendency of finding food, the sparrows with the white crown will suffer from poor diet and thus, will further generate less offspring, and so on.
Therefore, it is clear that for betterment, the sparrows with the yellow crown will evolve further due to their better skills of locating food, and this gives rise to the phenomenon of natural selection.

In the following exercise you will be given a wild type (ancestral) DNA code that you will transcribe and translate into an amino acid sequence (remember start codons). In addition to the wild type code, you have been given five mutated sequences of the wild type code that you will also transcribe and translate. For each mutation you will determine the mutation type (substitution, insertion, deletion) and effect (silent, nonsense, missense, frameshift-missense, frameshift-nonsense) by comparing to the wild type. Wild type template strand:
3'TGTACTTCAAACCGATT5"
mRNA-
AA Seq.
Answer:
Wild type template strand

Rice is an important food crop in the the world. Growing rice requires large amounts of water because the roots of rice plants must remain under water. Explain how genes could play a role in helping farmers grow rice using less water. 2 sentences, explain they could do (answerrrr ASAP)
Answer:
Rice plants possesses several traits which allow sthem to grow in large amount of water because standing water helps them to produce air channel known as aerenchyma that connects roots with shoots and transport oxygen to submerged tissues. Standing water also help many weed to grow and rice plants also takes nutrients from them as well.
Genes are responsible for the traits that allow rice plants to grow in large amount of water but if the gene of rice plant is genetically modified with new gene which is resistant to drought, that can allow the rice to grow in less water.
The genetically modified rice plant then do not require large amount of water and can grow easily.
3. How does the cell use both DNA and RNA to direct protein synthesis?
Answer:
proteins are made in the cell cytoplasm on tiny structures called ribosomes,to make proteins ribosomes use a code in the DNA
DNA is found in the cells nucleus and cannot move ,so the cell needs to get the code from the DNA to the ribosome this is done using a molecule called RNA (mRAN) - which is made by copying the code from DNA , the RNA acts as a messenger between the DNA and the ribosome - it carries the code between the two

Explain how a long-term environmental change can lead to the development of a new species
Answer: When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to specification, which is the development of a new species.
Explanation: its the sample response on edge so its right
). You are studying an allele T that governs parasite resistance in a large population of gazelles. You observe that different combinations of T and t produce phenotypes that have different fitnesses due to differences in parasite resistance. The fitness of TT is 0.30, the fitness of Tt is 0.32, while the fitness of tt is 0.34. The T allele starts at a frequency of 0.70, while t starts at a frequency of 0.3. i. Assuming Hardy-Weinberg equilibrium except for selection, what will the frequency of T be in the next generation
Answer:
The New Allelic frequency of the T allele in the next generation is 0.6865
Explanation:
In the attached file you will find the resolved problem.
You will probably need the definitions of the following terms:
Initial allelic frequency: (number of homozygote individuals + half number of heterozygote individuals) / Total number of individuals Relative contribution of each genotype: Zygote frequency x Relative aptitude Average aptitude W: It is the sum of relative contribution of each genotype to the next generation.WTT x p2 + WTt x 2 x p x q + Wtt x q2
Population Genotype frequency: Relative contribution of each genotype / Average aptitude Allelic frequency: Homozygote population genotype frequency + half heterozygote population genotype frequencyWhat happens during interphase that allows the two resulting cells to be the same as the
original cell?
Answer:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. ... Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.

Which of the following statements concerning metagenomic sequencing is incorrect
Answer:
The correct answer is "proteins are extracted from an environment, fragmented, and adaptors are added".
Explanation:
The missing options of this question are:
A) Software aligns sequences and assemble large portions of genome.
B) The samples are subject to polymerase chain reaction for amplification.
C) The sequences of the amplified fragments are determined by next-generation methods.
D) Proteins are extracted from an environment, fragmented, and adaptors are added
The correct answer is option D) Proteins are extracted from an environment, fragmented, and adaptors are added.
Metagenomic sequencing refers to the amplification and determination of all nucleotide sequences in a sample, which might contain multiple microorganisms and viruses in order to understand the presence and proportions of microbiota. Metagenomic sequencing involves the use of next-generation methods, to amplify and characterize all the nucleotides sequences. It is false to affirm that the proteins are extracted directly from the environment in this technique, since metagenomic sequencing is focused on the nucleotide sequences.
