Answer:
The answer is no, high biological fitness in one environment doesn't have to be high in another environment. Biological fitness is a term used in evolutionary biology and it is the quantitative representation of how a genotype (or phenotype) is successful (reproductively) in a certain environment. The biological fitness of an organism is dependent on its ability to survive and reproduce in a given environment. If different traits or alleles increase the fitness of an organism, those alleles will consequently increase in the gene pool, and that trait will increase in the population.

Answer:
1. A 2.B 3.B 4. C 5.5.
Explanation:
BB, Bb and bb are examples of?
dominant
recessive
genotypes
phenotypes
BB, Bb and bb are examples of genotypes. Thus, the correct answer is genotype.
A genotype is the genetic constitution of a trait in an individual. It is the genotype that results in the particular phenotype. Phenotype is the observable result of the trait.
Capital letter indicates that the allele is dominant and for recessive allele, small letter is used. Thus, B indicates dominant allele of that trait and b indicates recessive allele for that trait.
Depending on the genotype, the individual can be homozygous dominant, homozygous recessive or heterozygous for a trait.
In this case, BB is for denoting homozygous dominant, Bb is for heterozygous dominant and bb is for homozygous recessive.

Aaron is learning about genetics in science class, and he made a list about what he learned
. An example of a trait is blue eyes
Genes are always passed from offspring to parents
• Traits can be common and uncommon in populations.
. Genes determine most physical traits
Aaron made a mistake on his list. Which of these statements fixes Aaron's mistake
Answer:
Genes are always passed from offspring to parents
Explanation:
Well parents pass on genes to an offspring for one for another the parent will not always pass a gene for a certain trait on, if the trait is not a dominate gene it has the chance of getting replaced by the other parent's more dominate trait

Random mutations may occur because a change in the order of nitrogen bases in a codon. One type of mutation involves a substitution of one of the nitrogen bases in a codon. What amino acid is called for by GGA codon?
Answer:
Alanine
Explanation:
Using the codon chart (see the attached image), that is, a chart of triplet codes and the corresponding amino acids that they represent, the amino acid called for by GCA codon is alanine.
There are 64 possible codons in nature from 4 nitrogen bases - adenine (A), guanine (G), cytosine (C), and uracil (U). The codes are degenerates because they represent only 20 naturally occurring amino acids. Hence, more than one codons codes for each amino acid. Apart from GCA, other codons that translate as alanine include GCU, GCC, and GCG.
name and describe the process occurring in the nucleus which results in the formation of an mRNA molecule
Messenger ribonucleic acid (mRNA) is the single-stranded biological molecule that resembles the hereditary sequence of the gene and is needed for coding the proteins molecules essential for cell function and growth.
Transcription is the process that occurs in the nucleus.
What is the process that synthesizes the mRNA?mRNA is the biological molecule that gets formed from the double-stranded DNA molecule by the process of Transcription in the nucleus of the cell.The replicated DNA undergoes a transcription process and it's one strand transcripts to form a single strand of the mRNA molecule with the help of the transcription factors.One of the DNA strands acts as a template for the formation of the pre mRNA molecule with the help of the RNA polymerase II enzyme. The pre molecule formed undergoes an elongation and the termination process and the final mature mRNA is formed.Therefore, transcription results in the formation of the mRNA.

Some bacteriostatic antibiotics work by binding to enzymes needed by bacteria to build proteins essential for their own growth and reproduction. These drugs act as inhibitors to the bacterial enzymes but they target enzymes we don't have. Now, imagine you overhear your friend saying "antibiotics kill bacteria so they must kill healthy human cells too and they must be avoided at all costs!" Kindly explain to your friend (who has very little science background) how it is possible to target bacteria based on enzyme specificity. Be sure to include how targeting these enzymes is effective at stopping the infection.
Answer: This statement ("antibiotics kill bacteria so they must kill healthy human cells too and they must be avoided at all costs!") is wrong and can be proven to be so in the following explanation about the mode of actions of antibiotics.
Explanation:
Antibiotics are drugs which are used for the treatment of diseases caused by bacteria microorganisms. According to their mode of action, they can either be bactericidal or bacteriostatic.
Bacteriostatic antibiotics work by binding to enzymes needed by bacteria to build proteins essential for their own growth and reproduction. Atypical example is the antibiotics, sulfonamide. This drug acts by inhibiting a critical enzyme called dihydropteroate synthase which are specific to the metabolic pathway of the bacteria cells for the synthesis of folic acid. This causes the bacteria to stop growing. Together with the actions of the immune system, the bacteriostatic actions of the antibiotics can effectively stop am infection without affecting the host cells.

Answer:
Studies have shown that drinking 17 ounces (0.5 liters) of water increases resting metabolism by 10–30% for about an hour ( 22 , 23 ). This calorie-burning effect may be even greater if you drink cold water, as your body uses energy to heat it up to body temperature ( 21 , 24 ). Water can also help fill you up.

Answer:
UNA CADENA ALIMENTARIA ES LA RELACON ENTRE LOS MIEMBROS DE UN ECOSISTEMA PARA QUE UNA PARTE DE LA -ENERGIA- SEA TRANSFERIDA ENTRE ELLOS
ExplanatioN:
La cadena trófica es un procesos de tranferencia de energía entre distintos organismos de un ecosistema, en el cual cada organismo en un nivel se alimenta de organismos provenientes del nivel anterior y es comido por organismos del nivel siguiente. Los primeros eslabones de la cadena son autótrofos (fotoautotrofos o quimioautotrofos), productores que sintetizan la materia orgánica a partir de productos inorgánicos. Los eslabones siguientes son los consumidores heterótrofos: herbívoros, carnívoros, detritívoros.
Paso de energía entre niveles:
Del total de energía que llega a la superficie terrestre, solo el 1% es tomado por los fotoautótrofos. Esta energía adquirida que ingresa a la cadena trófica, tiene un recorrido unidereccional por donde pasa de nivel a nivel, desde los autótrofos hasta los heterótrofos, hasta que finalmente esa energia es disipada nuevamente en el ambiente.
Regla del 10%:
Esta regla establece que solo el 10% de energía utilizada por un nivel trófico pasa al siguiente nivel trófico. Solo el 10% de energía almacenada como biomasa en uno de los niveles tróficos, por unidad de tiempo, se convierte en energia almacenada del siguiente nivel trófico.
Esta progresiva reduccion de energía determina en número de niveles tróficos en esa cadena, que puede ser de cuatro o cinco eslabones.
Question 9 (1 point)
In peas, long stem (A) is dominant over short stem (a). A heterozygous, long stem plant (Aa) is crossed with a homo-zygous, short stemmed plant (aa).
Which of the above squares represent plants that are heterozygous?
Question 9 options:
Box 1
Box 1 and box 2
Box 1 and box 3
Box 2 and box 3
Answer:
Box 1 and 3
Explanation:
Box 1 represents the allele Aa
Box 2 represents the allele aa
Box 3 represents the allele Aa
Box 4 represents the allele aa
So the answer is Box 1 and 3 because Aa is a heterozygous allele and aa is a homo-zygous allele.
A cross among individuals with contrasting variations at one locus for the attribute is called a monohybrid cross. Each parent provides one type of allele or a trait to their offspring.
Monohybrid cross can be shown using the Punnett square, to determine the probability of a progeny expressing that genotype.
The correct answer is :
Option C. Box 1 and box 3
The reason for the answer is:
1. Box 1 will produce offspring with genotype: Aa
2. Box 2 will produce offspring with genotype: aa
3. Box 3 will produce offspring with genotype: Aa
4. Box 4 will produce offspring with genotype: aa
Therefore, Box 1 and Box 3 represents heterozygous alleles, whereas box 2 and box 4 represents purebred alleles.
