En las plantas de guisante la forma lisa de la vaina (cubierta) es dominante sobre la forma rugosa. Se cruzan plantas de vaina lisa con plantas de vaina rugosa, ambas homocigotas. Determine fenotipo y genotipo de F1 y F2.Resultante
Answer:
F1)
Genotipo: 100% Heterocigota, LlFenotipo: 100% Frutos de vaina lisaF2)

Answer:
Fires often remove alien plants that compete with native species for nutrients and space, and remove undergrowth, which allows sunlight to reach the forest floor, thereby supporting the growth of native species. ... Overall, fire is a catalyst for promoting biological diversity and healthy ecosystems.

The old strand of DNA reads TACGAATAG. Enzyme B makes the
new RNA strand:
OUACGAAUAC
ATG CITATG
AUG CUU AUC
AUGGUUUAUC
QUESTION 14
1 points
Save Answer
Answer:
The correct answer would be - AUGCUUAUC
Explanation:
The new mRNA strands are made by the process called transcription that involves an enzyme that helps to copy a segment of DNA or gene to produce a new RNA strand that encodes for the protein. In this process, a new RNA strand copied the complementary to the sequence of DNA strand. It means adenosine is copied into its complementary form uracil in RNA, Thymin to adenosine, cytosine to guanine and guanine to cytosine.
Original strands: TACGAATAG
new RNA strand: AUGCUUAUC

c. Nervous system
d. All of the above
Answer:
No. B
8 think so
I hope it helps ✌️
Explanation:
Parasitic flatworm do not have a digestive system because they don't digest there food. They just suck it when the upper gut muscles contract, suck it inside their body then gobble them up and then they're done sucking the nutrients from the food people eat.
Answer:
A. Digestive system

A.A gene can code for a specific protein
B.A gene can exist in alternate forms called alleles

D.A gene that is very similar in sequence in a human and in a bacterium is probably a recent mutation.
E.If parents do not express a gene but their child does, that gene is probably recessive.
A biologist wants to measure the effect of gene flow between populations. Which of the following investigations will allow her to accomplish this goal?
A)An investigation that determines a change in allelic frequency of a wolf population by theimmigration of a wolf from another population.
B)An investigation that determines the amount of time it takes for genes from a bee to transfer to the flower it fertilizes.
C)An investigation that determines the causes of mutations in genes that one species of guinea pig transfer to another species of guinea pig.
D)An investigation that determines the rate at which an antibiotic prevents a virus from transferring genes to a cat.
Answer:
B
Explanation:
Cause I say so
The investigation that will allow a biologist to measure the effect of gene flow between populations is that a change in allelic frequency of a wolf population by the immigration of a wolf from another population. Thus, the correct option for this question is A.
What is Population?A population may be defined as a group of individuals belonging to the same species living in the same area at a given time. The size, density, abundance, birth rate, death rate, dispersal, etc. are categorized as the characteristics of a population. These characteristics are known as demographic factors.
According to the context of this question, the process of gene flow can be determined by collating allele frequencies of populations. With this mechanism, if the two populations have increased variation in their gene pool, it expresses a lesser amount of gene flow because gene flow increases homogeneity among different populations.
Therefore, the correct option for this question is A.

Mitchell's family has the unusual trait of having an extra finger. Many members of his family were with an extra finger, which is a recessive trait. a family dinner, Mitchell's grandmother helped him sketch a pedigree of the family. Dark-shaded family members were born with an extra finger. No shading indicates people who do not have an extra finger. A question mari means it is unknown. Mitchell is #8 on the pedigree and grandmother is #2. Based on the pedigree what do you predict members number 12 number 11 and 13.
Answer:

What are new stars that are found in the spiral arms and formed from recycled dead star material known as?
population II stars
red dwarf stars
population I stars
brown dwarf stars
Answer:
population I stars.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).
The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.
Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.
New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.
A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.
