Answer:
Stigma
Explanation:
For pollination to occur, when a butterfly having pollen on the legs lands on flowers, the pollen needs to be deposited on receptive surface of pistil called stigma. There the pollen germinates and make a pollen tube which then reaches down to the ovules through pistils.

What is the success rate of implementation of transgenic embryos in surrogate dams? A) 50% B)100% C)25% D)<12.5% E12.5%
Answer:
D)<12.5%
Explanation:
Transgenic means one or more than one DNA sequences are introduced from another species by an artificial means into a surrogate dams to form a new offspring. Animals are usually make transgenic by a small sequence of the foreign DNA which is injected to the developing embryo of the surrogate mother.
The success rate for such implementation is nearly less than 12.5%, where most of the trial do not survive the injection. The surrogate mother cannot developed in most cases the implementation of one or more species into another.

A study has shown 75% of teenage boys drink 1 liter of soda per day. How many 250 ML cans of soda would a boy drink in a week if he drank 1L per day?
According to the study, if the boy drinks one liter of soda per day then, he will drink 28 soda cans of 250mL volume in a week (seven days). Each day, he drink four cans of 250mL.
What is Soda drink?A soft drink is a drink which usually contains water, artificial sweeteners, and a natural or artificial flavoring agent. The sweetener used in the soda drink can be a sugar, high-fructose corn syrup, fruit juice, a sugar substitute, or combination of these compounds. They may also contain caffeine, coloring, preservatives, and other ingredients.
If a boy drinks 1 liter of soda per day. Then, the number of cans of 250mL soda he drinks in a day will be:
1 liter = 1000mL
Number of cans which a boy drinks in a day = 1000mL/ 250mL
Number of cans of soda = 4
The number of cans which a boy drink in a week i.e., 7 days = Number of cans which a boy drink in a day × number of days in a week
Therefore, the number of cans which a boy drink in a week = 4 × 7
The number of cans of soda = 28
Therefore, the boy drinks 28 cans of soda in a week.

what would be the complementary RNA strand for a portion of the DNA that reads as follows: T-A-G-A-C-G-T-A-G
Answer:
R
Explanation:
Remember that
A
is adenine,
G
is guanine,
C
is cytosine, and
T
is thymine.
The complementary RNA strand for T-A-G-A-C-G-T-A-G DNA portion is A-U-C-U-G-C-A-U-C.
What is complementary RNA?"Complementary RNA is a copy of a strand of RNA that will bind to the appropriate region of the original molecule."RNA contains nucleosides- Adenine, Guanine, Cytosine and Uracil (In DNA Thymine is present instead of Uracil)Adenine bonds with Uracil and Guanine with Cytosine.Hence, A-U-C-U-G-C-A-U-C is the complementary RNA strand.

The graph below shows the populations of two species from January 2010 to June 2011. One species is native to the ecosystem, while the other is a new species that was recently introduced to the ecosystem.
What is the most likely explanation for the changes to the populations of species A and species B?
Species A is a native species that preys on species B.
Species B is an invasive species that altered the balance of the ecosystem shown.
Species A is an invasive species that cannot compete with the native species in the habitat.
Species B is a native species that is able to adapt to a sudden climate change while species A cannot.
Answer:
Species B is an invasive species that altered the balance of the ecosystem shown.
Explanation
An invasive species is an introduced organism that negatively alters its new environment
How do mutations in DNA lead to genetic variation within a species?
O A. They increase the rate at which parents can produce offspring..
O B. They result in new traits being inherited by offspring from their
parents.
O C. They cause offspring to have the exact same DNA as their
parents
O D. They reduce the amount of time it takes parents to produce
offspring
CHE
Answer:
B) They result in new traits being inherited by offspring from their
parents.
Explanation:
Suppose a trait is controlled by a gene that has one dominant allele (G) and one recessive allele (g).
Which of the following crosses would be expected to produce the greatest variety of genotypes among the offspring?
Answer:
Gg x Gg
Explanation:
Gg x Gg crosses would be expected to produce the greatest variety of genotypes among the offspring.
What is Punnett Square?A Punnett square is defined as a graphical representation of the possible genotypes of the offspring resulting from a particular cross or breeding event. Creating a Punnett square requires knowledge of the genetic makeup of the parents.
For a monohybrid cross, Punnett squares are 2X2 squares containing four boxes where each represents a fertilization event between the original gametes. While the second type is used to predict the outcome of breeding experiments where two traits are being observed and the Punnett square is large with sixteen boxes.
In the above example, if a Gg x Gg cross occurs, the genotype for the children will be Gg, which would be expected to produce the greatest diversity of genotypes among the offspring, i.e. 100%.
Thus, Gg x Gg crosses would be expected to produce the greatest variety of genotypes among the offspring.

ATTTGCATGCA
Answer:
UAAACGUACGU
Explanation:
You want us to transcribe ATTTGCATGCA. Remember that in transcription, we don't use thymine (T) we use uracil (U). This means that adenine (A) will pair with uracil (U). Let's begin:
A --> U
T --> A
T --> A
T --> A
G --> C
C --> G
A --> U
T --> A
G --> C
C --> G
A --> U
So, the answer is UAAACGUACGU
Answer:
UAAACGUACGU
Explanation:
When transcribing....
Adenine (A) Transcribes to Uracil (U)
Thymine (T) Transcribes to Adenine (A)
Cytosine (C) Transcribes to Guanine (G)
and Guanine (G) Transcribes to Cytosine (C)
So if the DNA strand, ATTTGCATGCA were to be transcribed
A would change to U
T to A
T to A
T to A
Etc.
We would end up with UAAACGUACGU
Photosynthesis takes place in the _______________ and releases __________________.
A. mitochondria, oxygen
B. chloroplast, oxygen
C. mitochondria, carbon dioxide
D. chloroplast, carbon dioxide
Answer:
B. chloroplast, oxygen
Explanation:
This is because plants take in the carbon, water, air,and it transforms the water into oxygen and carbon into glucose. So it absorbs light, and the chloroplasts are special structures that are responsible for that absorption of light, They are green, because of chlorophyll, which gives the green pigment to leafs
photosynthesis takes place inside them, so they can absorb light to start the process.

What kind of isolation occurs when two populations of birds have different courtship dances?
Answer: Also known as ethological isolation, behavioral isolation occurs when two populations are capable of interbreeding but don't because of differences in their courtship rituals.
average clutch Size: Two eggs
Predators: Humans, owls, and birds of prey
Main Prey Species: Small fish such as sardines ...
Species: Six
Explanation:
Behavioral isolation occurs when two populations of birds have different courtship dances.
What is Behavioral isolation ?Behavioral isolation is defined as when a species becomes reproductively isolated from others due to differences in behavior. It is one way in which nature prevents the inbreeding of species through behavioral differences.
This occurs when populations of the same species begin to develop distinct behaviors that are not recognized or preferred by members in another population. An example of behavioral difference is the mating call when two populations of the same species may have slightly different mating calls.
Thus, Behavioral isolation occurs when two populations of birds have different courtship dances.
