Explanation:
If the purple flowering pea plant alleles (F) are dominant and the white flowering pea
plant alleles (t) are recessive, then what is the phenotype for the genotype (Ff) of the offspring? Explain your response.
Answer:
Purple flowers
Explanation:
F is dominant over the recessive trait of t. So F is the trait that will be expressed, rather than t
what trait only appears when a organism is a homzygous
Answer:
Both can show.
Explanation:
The genotype can look like the following:
TT <= Homzygous Dominant
tt <= Homzyogous Recessive
Tt <= Heterzygous
See? It would be hard to determine exactly which trait would show without the second half of the name! (By the way, I can't say the proper names so I apologize)
I hope this helps! ^-^

A new dog breed is less likely to cause an allergic reaction in humans. Which statement explains how artificial selection led to the development of this desirable trait?
Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.
Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.
Different dog breeds were chosen for nonallergic traits and bred with each other to obtain the new dog breed.
Dogs were trained over generations to not produce and release proteins that cause allergic reactions in humans to obtain the new dog breed.
Dogs were kept outdoors over generations to build up a natural defense against allergens in the environment to obtain the new dog breed.
Answer:it is c
Explanation:cuz it is
Answer:
C
Explanation:
Because they would test the dogs for traits and then selectively breed them
What additional information would you want to know to understand Emma and Jacob's panic? Include a minimum of three examples.
The correct answer to this open question is the following.
Unfortunately, you did not attach the story, the text, or the name of the article/text. Without this important information is so difficult to help you.
However, trying to help you, we did some deep search and can comment on the following.
The additional information you would want to know to understand Emma and Jacob's panic is the following.
First, you want to understand what is the real cause of the parent's panic. And all comes down to the health of their baby. The baby had problems with feeding. What happened was that Emma's baby stopped feeding after seven days.
This couple had lost a baby that died in the first nine days with no clear explanations at all. So they were traumatized by that fact and do not want to have another traumatic experience again. That is why they are afraid.
The parents desire the baby to feed normally and have the correct weight.
Parents are afraid that the baby dies or if it survives, could end up with some illness or mental ret*rdation, or could have another kind of complications when the baby is growing up.
Explain why when the DNA is being replicated during the S phase of the cell cycle, it copies each strand differently.
Answer: Each strand act as a template strand for another strand this way two strands are responsible for the production of two new strands. This way after the replication process two DNA molecules are produced.
Explanation:
S phase of the cell cycle is the synthesis phase of the cell cycle. This phase occurs after the interphase of the cell cycle. In this phase, the replication and synthesis of the DNA occur. The genetic material gets copied and doubled in this process before it enters into mitosis or meiosis. Each strand is utilized as a template strand for the synthesis of the complementary strand this way two molecules of DNA are produced. This way each cell contains a diploid set of chromosomes before it undergoes cell division into daughter cells in mitosis or meiosis.
Each strand act as a template strand for some other strand this manner strand is accountable for the manufacturing of new strands. In this manner after the replication system DNA molecules are produced.
S phase of the cell cycle is the synthesis section of the cell cycle. This section happens after the interphase of the cell cycle. In this section, the replication and synthesis of the DNA arise. The genetic material receives copied and doubled on molecular this system earlier than it enters into mitosis or meiosis.
Each strand is applied as a template strand for the synthesis of the complementary strand this manner molecules of DNA are produced. In this manner, every cell carries a diploid set of chromosomes earlier than it undergoes cell department into daughter cells in mitosis or meiosis.
What is the S phase?S phase (Synthesis Phase) is the section of the cell cycle wherein DNA is replicated, taking place among the G1 phase and G2 phase. Since correct duplication of the genome is essential to a successful cellular department, the techniques that arise for the duration of the S-phase are tightly regulated and broadly conserved.
Hence it states that the DNA is being replicated during the S phase of the cell cycle, it copies each strand differently.

Explanation:
Does DNA undergoes translation to produce proteins . RNA undergoes mutation to produce cell walls
Answer:
No
2. Yes
Explanation:
This is because DNA undergo transcription to produce RNA and RNA undergo translation to produce protein. Translation is the process where mRNA molecule is used as a template to produce protein.
RNA undergo mutation more than DNA and this is because the enzymes found in RNA viruses and participate in copying viral genomes is why it occur so. These enzymes does not have the abilities to recognize DNA damage that enzymes in most organisms have.

A population of African lions share the same habitat. A small group becomes reproductively isolated
from the rest of the population (mating behaviors no longer match). What type of speciation is this?
a. Allopatric speciation
b. Sympatric speciation
C. Parapatric speciation
d. Peripatric speciation
Answer:
The correct answer is - B. sympatric speciation.
Explanation:
The allopatric speciation occurs in the population that is geographically isolated, parapatric speciation takes place due to reproductive isolation however they occupy distinct nice or habitat.
Peripatric speciation is shows resemblance to allopatric speciation in terms of preventing the exchange of genes however they occur in the small peripheral population.
Sympatric produces a reproductive barrier between the small population that shows change to the parent population.

The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. View Available Hint(s) The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. a transport protein is involved in the movement of the molecules the lipid bilayer is permeable to the solute the concentration of the solute is lower inside the cell than outside it the concentration of the solute is higher inside the cell than outside it
Answer:
the concentration of the solute is lower inside the cell than outside it
Explanation:
This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.
This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.
How do both sodium and potassium ions travel
Answer:
Sodium ions pass through channels in the hydrophobic barrier that have been formed by membrane proteins. The crossing membrane is called facilitated diffusion because it is facilitated by the channel
Potassium ions have to be transocated through specific membrane transport proteins. It is then transported into the cell through potassium pumps with energy being consumed int the form of ATP.
The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP.
Explanation:
Answer:
The sodium potassium pump goes through cycles of shape changes . In this way they help maintain a negative membrane potential. In each cycle, two potassium ions enter the cell while three sodium ions exit the cell . These ions travel against the concentration gradient. And this process requires ATP.
