Answer:
By crossing plants with purple flowers, dominant, with plants with white flowers the offspring will be 100% purple because all the offspring will receive at least one dominant allele.
Explanation:
The crossing of two plants of pure line, one dominant and one recessive, for a trait —the color of the flowers— will produce a hybrid offspring which will express the dominant trait in its phenotype.
Parental generation:
Plant with purple flowers PP Plant with white flowers ppCross: PP X pp
Punnett Square :
Alleles P P
p Pp Pp
p Pp Pp
Offspring: 100% Plants whose phenotype is purple flowers and Pp genotype.
According to this, the descendants will be 100% plants with purple flowers, hybrids, since all the offspring received at least one dominant allele.

Answer:
D
Explanation:
Thymine is to DNA as uracil is to
A. RNA
B. adenine
C. ATP
D. Protein
Answer:
A. RNA
Explanation:
DNA has the chemical base of thymine, while RNA does not.
Instead, RNA has the base of uracil, to replace thymine.
Since the analogy relates thymine to DNA, uracil must be related to RNA.
So, A is the correct answer.
Thymine is to DNA as Uracil is to RNA.
What is the anatomy of a leaf
Answer:
Typically, a leaf consists of a broad expanded blade (the lamina), attached to the plant stem by a stalklike petiole. In angiosperms leaves commonly have a pair of structures known as stipules, which are located on each side of the leaf base and may resemble scales, spines, glands, or leaflike structures.

Why is DNA in the world?
Answer: Nine years ago I jumped at an opportunity to join the international team that was identifying the sequence of DNA bases, or “letters,” in the genome of the common chimpanzee (Pan troglodytes). As a biostatistician with a long-standing interest in human origins, I was eager to line up the human DNA sequence next to that of our closest living relative and take stock. A humbling truth emerged: our DNA blueprints are nearly 99 percent identical to theirs. That is, of the three billion letters that make up the human genome, only 15 million of them—less than 1 percent—have changed in the six million years or so since the human and chimp lineages diverged.
Evolutionary theory holds that the vast majority of these changes had little or no effect on our biology. But somewhere among those roughly 15 million bases lay the differences that made us human. I was determined to find them. Since then, I and others have made tantalizing progress in identifying a number of DNA sequences that set us apart from chimps.

by parasitic
sorry if wrong
Answer:
This is true.
Explanation:
Some plants are parasitic, which means they do not make their own food. They do, however, steal necessary water and minerals from other plants, often killing the other plants off. Parasitic plants sometimes do have chlorophyll, and others do not.
what causes the splitting of the phosphate group off of ATP
Answer:
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).
Explanation:
People who have Tay-Sachs disease cannot metabolize some lipids effectively. Tay-Sachs is a recessive disorder. A student used a Punnet Square to determine the probability of offspring inheriting the disease. The results from a Punnet Square are 25% TT, 50% Tt, and 25% tt.
Which conclusion can be made regarding the phenotype of the parents based on these results?
The parents must be TT, Tt
The parents must be Tt, tt
The parents must be TT, tt
The parents must be Tt, Tt
Answer:
The parents must be Tt, Tt
Explanation:
Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:
T t
T TT Tt
t Tt tt
We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).
This means that the parents must be Tt, Tt.
What is the definition of Osmosis?
Answer:
a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
Explanation:
Osmosis is a special case of diffusion. Water, like other substances, moves from an area of higher concentration to one of lower concentration. ... In this example, the solute cannot diffuse through the membrane, but the water can. Water has a concentration gradient in this system....!!!!!!!!!...!!!!!!

Si una planta homocigótica de tallo alto (AA) se cruza con una homocigótica de tallo enano (aa), sabiendo que el tallo alto es dominante sobre el tallo enano, ¿Cómo serán los genotipos y fenotipos de la F1?
Answer:
Genotipo: 4/4 o 100% de la progenie será Heterocigota para la característica altura del tallo, Aa.Fenotipo: 4/4 o 100% de la progenie expresará tallos altos.Explanation:
Datos disponibles:
Característica: Altura del talloAlelo dominante, A, expresa tallo alto en homocigosis (AA) y en heterocigosis (Aa).Alelo recesivo, a, expresa tallo enano en homocigosis (aa).Cruza: una planta homocigótica de tallo alto con una homocigótica de tallo enano (aa)
Parentales) AA x aa
Fenotipos) Tallo alto Tallo enano
Gametos) A A a a
Cuadro de Punnet) A A
a Aa Aa
a Aa Aa
F1) Genotipo: 4/4 o 100% de la progenie será Heterocigota para la característica altura del tallo, Aa.
Fenotipo: 4/4 o 100% de la progenie expresará tallos altos.
Nota: Por conocimiento teórico, es posible que no sea necesario el uso del cuadro de Punnet para realizar esta cruza. Esto es porque sabiendo que uno de los parentales es homocigota dominante y el otro parental homocigota recesivo, con un solo gen dialélico involucrado en la cruza, indefectiblemente la progenie será heterocigota. Un parental solo puede ofrecer gametos dominantes para la característica mientras que el otro parental solo puede ofrecer gametos recesivos. Aún asi, el cuadro de Punnet siempre resulta útil para poder visualizar bien los cruzamientos, siempre que estos últmos involucren pocos genes.

When an antigen attacks the body, it activates adaptive immunity. This adaptive immunity produces a strong response when it encounters the same antigen for the second time. Which feature of adaptive immunity is essential for this kind of response?
Answer:
A) the ability to remember the antigen it encounters
Adaptative immunity reacts in a more general way producing nonspecific antibodies against the foreign antigen when the organism is first attacked by that foreign antigen. The second time around, when the organism is faced again with the same foreign antigen, it produces a much stronger response because it memorised the antigen and is not strange anymore so the response can be more specific, quicker, and effective.
Explanation:
Answer:
Explanation:
memory T cells plays an important role in fighting against microbe which encounter the body for second time
John and Sarah had a child born with cystic fibrosis, a genetic disease. Both John and Sarah were normal, showing no signs of this disorder. How is it possible for them to have a child with this disease?
a. Cystic fibrosis must be a dominant trait disorder hidden in both parents' genotype, but not showing in the phenotype, that could be passed on to offspring.
b.Cystic fibrosis must be a recessive trait disorder hidden in both parents’ genotype, but not showing in the phenotype, that could be passed on to offspring.
c. Cystic fibrosis must be a dominant trait disorder hidden in one parents’ genotype, but not showing in the phenotype, that could be passed on to offspring.
d.Cystic fibrosis must be a recessive trait disorder hidden in one parents’ genotype, but not showing in the phenotype, that could be passed on to offspring
Answer:
B
My logic:
I did a whole project on genetics and i love genetics. I know for a fact this is the correct answer because i had it 2 years ago on a test and got it correct. On the off chance im wrong, it has been 2 years and i might have mixed my facts up.
Hope this helps!
Answer:
it is b
Explanation:
reccesive doesn show in the phenotype because its covered by the dominant trait so the parents were fine but it is both parents so that the kid has an rr and not Rr or RR so that the reccesive trait would be covered by the dominant in the phenotype so B
