Answer:
No, they are not. The concept of human races appears to be solidly grounded in present-day biology and our evolutionary history. But if you asked that conference of geneticists to give you a genetic definition of race, they wouldn’t be able to do it. Human races are not natural genetic groups; they are socially constructed categories. Genes certainly reflect geography, but unlike geography, human genetic differences don't fall along obvious natural boundaries that might define races.
What cell function can fail resulting in cancer development?
Answer:
cell division
Explanation:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

what is the difference between an alligator and a crocodile
Snout Shape: Alligators have a wide, rounded, u-shaped snout, while crocodiles have long, pointed, v-shaped snouts. ... Crocodiles are different from alligators in this sense, where both upper and lower jaws of a crocodile are the same size, exposing their teeth as they interlock, creating the look of a toothy grin.
Alligators have U-shaped faces that are wide and short, while crocodiles have thin V-shaped muzzles. When an alligator closes its mouth, you tend to see only its upper teeth. Crocodiles on the other hand flash a toothy grin with their top and bottom teeth interlacing.
Scientists have been studying four populations in a swamp area. In this area, alligators eat gar (a type of large fish), and both gar and diving ducks eat crabs. The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and the crab population will change, and why.
Answer:
There wouldn't be enough resources for the alligator population to live off of thus decreasing its population number. This decrease affects the other populations because it without alligators, its predators and prey wouldn't gain its nutrition from it and it would overall change its environments' habitation. The gar population would increase because they wouldn't be eaten by the alligators and therefore increasing the diving duck population as well. The crab population would decrease because the gar (their prey) population increased which overcomes the number of crab in the population.

what is respiration and the different types
Answer:
It involves inhalation and exhalation of gases. Internal respiration involves gas exchange between the blood and body cells. Cellular respiration involves the conversion of food to energy. Aerobic respiration is a cellular respiration that requires oxygen while anaerobic respiration does not.

Answer:
Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T) as the complementary nucleotide to adenine

Blue poppies native to China were grown at a plant-breeding center in California. The plants with the thickest leaves were most likely to survive and reproduce in the drier climate. After several generations, the percentage of thick-leaved plants had increased by 42%. This adaptation of the poppies to their new environment is due to _____.

The plants with the thickest leaves were most likely to survive and reproduce in the drier climate. After several generations, the percentage of thick-leaved plants had increased by 42%. This adaptation of the poppies to their new environment is due to _____. See Concept 23.4 (Page 495) disruptive selection neutral variation directional selection genetic drift stabilizing selection
Answer:
directional selection
Explanation:
Directional selection is a type of natural selection where individuals exhibiting an extreme phenotype for a given trait are favored over the mean or other extreme phenotype. This type of selection can lead to drastic and fast changes in allele frequencies between generations in a population, being particularly important in speciation processes. Directional selection is common under environmental changing conditions (e.g., weather, climate, food availability, etc) or when individuals migrate to other regions in order to adapt to new environmental pressures.
Period of a wave refers to...
Answer:
The period of a wave is the time for a particle on a medium to make one complete vibrational cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years. The period of orbit for the Earth around the Sun is approximately 365 days; it takes 365 days for the Earth to complete a cycle.

Alex is studying a population of fifty organisms that belong to the same species. Some of the organisms have dark spots, some have light spots, some have no spots, and some have stripes.
How does this species most likely reproduce?
Answer:
Sexual reproduction
Explanation:
There is a significant amount of genetic variation (diversity) here. Asexual reproduction results in little to no diversity, so we can assume this species reproduces sexually. Hope it helps :)
How could different nucleotide sequences result in the same amino acid
sequences?
Answer:
There is more than one codon that can specify most amino acids, therefore you never know which one was used for a particular protein, unless you can look at the DNA or RNA sequence.

What’s the answer please??!!!
Answer:
A
Explanation:
Almost all embryos of vertabrites look the same at early embryo stages, even humans to other organisms. This is because they all have a common ancestory, adn orginated from a organism with an embryo that looked like this.
It is clear it cannot be the other answers for the folowing reasons:
The organisms will definatly not look the same, considering they are birds and reptiles. The 2nd answer speaking of geography isnt very accurate, and cannot be determined because as I said above, any vertibrate embro looks very similar, and close geopgraphy isnt what made them look similar.
Again, all vertabrites have the same embryos, and that is a phylum. Not a genus. There are many genus in a phylum, and the ecaxt one cannot be determines.
As I said above, HUMANS look simiar to BIRDS and REPTILES, but clearly grow to be much different.
Answer:
A: the organisms share a common ancestory

Which mutation scenario will always lead to natural selection?(1 point) A. a mutation causes a specific advantage within the population B. a mutation causes an inactivated gene to be reactivated C. a mutation causes a specific variation within the population D. a mutation causes a gene to become inactivated
A mutation scenario that will lead to natural selection is one that causes a specific variation within the population. Thus, the correct option for this question is C.
What is Mutation?A mutation may be defined as a type of process that significantly involves sudden, stable, and inheritable changes in the genetic material of an organism. The organism that undergoes mutation is called a mutant. The agent of mutation is called mutagen.
According to the context of this question, the process of mutation never causes a positive influence on the organisms, but with respect to time organisms become adapted or habitual.
A Mutation may be random and spontaneous so, it does not always involve an inactivated gene being reactivated. It sometimes involves the introduction of a new gene that facilitates specific functions.
Therefore, a mutation causes a specific variation within the population is a mutation scenario that will lead to natural selection. Thus, the correct option for this question is C.

Is the following sentence true or false? During meiosis, the two alleles for each gene stay together.
Answer:
False
