Describe the three ways meiosis produces genetic variability. We have seen that meiosis creates variation three ways: crossing over, mutations caused during crossing over, and independent assortment.
Which of these is what DNA and RNA are? *
O A. lipids
O B. proteins
O C. nucleic acids
O D. carbohydrates
Answer: DNA and RNA are both examples of nucleic acids
They consist of a strand of nucleotides with a phosphate group, a 5′ sugar and a nitrogenous base.
Extra info: DNA and RNA molecules are polymers. DNA is double stranded, whereas RNA is single stranded.
The nucleotides of DNA can pair together by base pairing, creating a strand that is complementary to its pair
Various types of RNA exist which have roles in protein synthesis as well as regulation of cellular programmes by fine-tuning gene expression.

He continued to breed purple-flower producing pea plants together over six generations. The results of Ralph's artificial selection are shown above. What did artificial selection do to the population of pea plants? A. caused a new species of pea plant to form B. increased its genetic diversity C. decreased its genetic diversity D. caused a pea plant to exhibit a new characteristic
Answer:
C
Explanation:
The correct answer would be that artificial selection decreased the genetic diversity of the pea plant.
Genetic diversity is a measure of the number of traits or characters.
Initially, the breeding produced a considerable population of both white and purple flower offspring. But as time goes on, the population of purple flower offspring increased while that of the white flower decreased till it eventually reached zero.
Thus, artificial breeding reduced the number of traits in the population of the offspring from two to one - a case of reduction in genetic diversity.
The correct option is C.

Nuestro planeta esta habitada por numerosas ____, muchas de ellas extendidas en grandes y diversas zonas. Sin embargo, existen especies que habitan una sola ____ con características ____ únicas para su desarrollo.
Answer:
Nuestro planeta esta habitada por numerosas especies, muchas de ellas extendidas en grandes y diversas zonas. Sin embargo, existen especies que habitan una sola área/región con características ambientales únicas para su desarrollo.
Explanation:
Entre las miles de especies que habitan el planeta, muchas de ellas pueden estar ampliamente distribuidas, mostrando adaptaciones a una gran variedad de ambientes y hábitats, mientras que muchas otras solo se encuentran restringidas a determinadas areas o regiones particulares que presentan condiciones ambientales determinadas. Esta diferencia en distribución esta muy relacionada a la historia de la especie, a la edad de la misma sobre la tierra, adaptaciones a los ambientes y capacidades reproductivas y de dispersión.
Dentro de la clasificación de especies de acuerdo a su distribución, podemos mencionar a las especies
nativas: aquellas que habitan y se distribuyen las áreas naturales donde se originaron,endemicas: entran dentro del concepto de nativas, pero a parte se caracterizan por habitar unicamente una región en particular debido a las condiciones ambientales que les son propicias para su desarrollo. Estas especies no pueden trasladarse a otras regiones.exoticas: aquellas especies que salen de su area natural de distribución para habitar otras areas mas lejanas. Allí pueden establecerse e interactuar con especies nativas sin causar grandes daños.invasoras: especies exoticas que llegan a otras areas, que se establecen y que tienen la capacidad de reproducirse a una tasa superior a la de las especies nativas, invadiendolas y desplazandolas. Interactuan con las especies nativas y causan daños importantes.Los términos nativos, endemicos, exóticos son relativos al área a la que se esté haciendo alusión: un continente, un país, una región o un bioma.

Between a Black father bear (genotype BB) and a Brown mother bear (genotype bb), they had several baby bears.Black fur allele (B) is dominant overthe brown fur allele (b), what is the probabilityof their offspringhave blackfur?
Answer:
100% or 1
Explanation:
This question involves a gene coding for fur color in bears. According to the question, black fur allele (B) is dominant over the brown fur allele (b). This means that a bear heterozygous for fur color (Bb) will be phenotypically black.
In this question, a black father bear (genotype BB) and a brown mother bear (genotype bb) were crossed, the baby bears will all have a genotype Bb (see punnet square in the attached image). Since all the offsprings of this cross have genotype Bb, this means that 100% will have black fur.

Describe how a carbon atom is released from a fossil fuel like coal and travels into the atmosphere as a gas. How does it then end up in living things like plants and animals? Explain how carbon ends up back in the ground. Use the following terms in your typed response: CO2, C6H12O6, atmosphere, lithosphere, hydrosphere, biosphere, carbon sink, carbon source.
Explanation:
Animals and plants need to get rid of carbon dioxide (c02), this process is called respiration. Respiration happens when the plant/animal breaths in air and releases it as carbon, carbon then moves from fossil fuels to the atmosphere where they are burned. When humans burn fossil fuels to power cities, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.

What was one conflict that was resolved in the resolution?
The characters learned to respect each other enough to discuss why the boy tried to grab the purse.
Mrs. Jones took care of the boy's hunger.
The boy asked for the money to buy shoes.
Mrs. Jones taught the boy to have manners.
The answer is the boy asked for money
Answer:
The characters learned to respect each other enough to discuss why the boy tried to grab the purse.
Explanation:
In the short story "Thank You, Ma'am" by Langston Hughes, a young, hungry boy was about to rob a woman of her purse. But as circumstances would turn out, he was unsuccessful in that attempt but then learned a valuable lesson from the very woman he had targeted.
One conflict that was resolved in the resolution was that both of the characters, Mrs. Luella Bates Washington Jones and Roger, learned to respect one another. By her act of inviting him to her home and preparing food for him, Roger also came to respect and trust the woman. It was this faith that helped them discuss the events that led to Roger's failed attempt of robbing Mrs. Jones, and Roger left the house with a sense of appreciation and a change of heart.
Thus, the correct answer is the first option.

Jennifer is trying to determine the blood type of her parents for biology class. She knows that her blood type is B. In such case her father may have blood type A,B, AB, and O. Thus, option C is correct.
What is blood group?The three alleles that are A, B, and O are mainly responsible for controlling the major blood groups such as A, B, and AB, respectively. Due to this fact that humans are considered as diploid, each genotype could only include the maximum of two of them. Just to put it another way, just only two of these alleles could coexist in the single cell of the human at given time.
IA, IB, and I are considered as the three distinct alleles that could determine the person's blood type. I has been considered as the most common. These three alleles could be referred to as the A (for IA), B (for IB), and O for the sake of simplicity (for i). Because we receive one blood type allele from our biological mother and one from our biological father, each of us has two ABO blood type alleles.
Therefore, option C is correct.
