"Could you please help me? I have a question that is honestly NOT a homework
question. I am a Junior here at LTHS. "Could a man with type B blood and a
woman with type AB produce a child with type O blood?" I think not, because
type O is recessive, and the B's seem to be dominant. My cousin thinks yes.
Thank you for your help."

how does the operator region of dna work to regulate gene expression?.
Answer:The promoter is found in the DNA of the operon, upstream of (before) the genes. ... Some regulatory proteins are repressors that bind to pieces of DNA called operators. When bound to its operator, a repressor reduces transcription (e.g., by blocking RNA polymerase from moving forward on the DNA).
Explanation:
What is significant drawback to transferring electricity produced by solar where sunshine is abundant to states where it is not
Answer:
The transfer could only occur during the day because it cannot store solar energy.
Explanation:
The transfer of electricity produced from solar energy only occurs during the day because it cannot store solar energy at a tremendous level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, enormous batteries are needed to store it which can't be made because of very high cost so that's why the solar energy can not be stored.

Explain mendel's experiment with peas on inheritence of characters considering only one visible contrasting character.
Ples answer in making points, it is for 5 marks.
➜ Mendel conducted breeding experiments with garden peas:
[i] He studied plants (pure) of a tall/short varities.
[ii] He crossed them and obtained F1 progeny.
[iii] He found that F1 progeny was all tall plants.
[iv] He selfed the (hybrid) plants if F1 progeny.
[v] He found that in F2 progeny there were tall as well as short plants.
[vi] The three quarter plants were tall and one quarter was short.
(or any other contrasting character may be taken).
Note: Here, F1 means First fillial generation and F2 means Second fillial generation.
Mendel selected garden pea for his breeding experiment because of its contrasting characters such as height of the plant, yellow or green seed, round or wrinkled seed shape. ... Then he allowed the hybrid plants of F1 generation to self-pollinated. In F2 generation all the progeny were tall as well as short plants...We used to take this character, we may choose different.
A red frog and a blue frog mate and have offspring. If the gene is Codominant, what will be the color of their offspring?
Answer:
The correct answer is - blue and red both.
Explanation:
Codominance is the type of inheritance pattern in which alleles interact differently with one other. In this type of inheritance, neither allele is dominant or recessive and both traits are visible in the progeny if both alleles are present together in heterozygous conditions.
Here, in this case, Red frog and the blue frog are in codominance so the cross of these frogs leads to both colors that will be express in offspring together.
RR mate with BB
R R
B RB RB
B RB RB

Bird guides once listed the myrtle warbler and Audubon's warbler as distinct species because of differences in color patterns of the feathers and size of the beak. Recently these birds have been reclassified as eastern and western forms of a single species, the yellow-rumped warbler, based on the observation that the two forms interbreed often in nature and the offspring have good survival and reproduction. The earlier classification into two species was using a species concept; the reclassification is using the species concept. _________
Answer:
morphological; biological
Explanation:
The morphological species concept highlights the importance of physical traits to delimit species. This concept is useful for classifying asexually-reproducing organisms and where lack information on interbreeding (for example, to classify fossils). On the other hand, the biological species concept states that one species represent a group of organisms that can interbreed (or potentially can interbreed) in order to produce fertile offspring. The biological species concept is nowadays the most widely accepted concept to define species.
Why will doing a defibrillator cause the heart to pump ?
Answer:
it shocks the hearts muscles jolting the heart into working again.
Explanation:
Answer:
Defibrillation delivers an electrical shock that causes all the heart cells to contract at the same time. This stops the abnormal rhythm and allows the heart to restart normal electrical activity.
Explanation:
how is specific gravity extracted from the earth?
Answer:
The formula for specific gravity, given that the reference substance is water, is the density of the object divided by the density of the water.

Which of the following is the best example of a symbiotic relationship? The climate changes. As a result, hundreds of species become extinct and the land turns into a desert. A pair of birds fight over a piece of food. The dominant bird wins. Certain breeds of fish will often clean bigger fish. The cleaner fish gets food, the bigger fish gets a cleaning. A foolish man decides to go swimming in shark-infested waters. As a result, he is bitten by a shark looking for food.
Answer:
Certain breeds of fish will often clean bigger fish. The cleaner fish gets food, the bigger fish gets a cleaning.
Explanation:
I'm not too sure.

O Water is denser than isopropanol, so the water layer will always be below the isopropanol layer if they are both in the same container. What does this tell you about the make-up of the pigments for each specimen?
Answer:
One is polar and the other is non-polar.
Explanation:
The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.

Answer:
The Moon moves around Earth until the Moon is between the Sun and Earth.
Explanation:
Crossing over occurs at the ends of chromosomes, rather than near the centromeres. As a result of crossing over, sister chromatids are no longer identical to each other. For crossing over to occur, homologous chromosomes must align precisely early in prophase I so that nonsister chromatids can exchange corresponding segments of DNA. Crossing over prevents homologous chromosomes from separating during meiosis I.

The tree population on Galveston Island has become more diverse due to human impact and planting non-native trees. During times of hurricane flooding, native trees that are more tolerant to salt water are surviving while non-native trees that are less salt tolerant are dying off. Which of the following explains how the tree population will continue to change overtime?
The salt tolerant tree population will decrease overtime due to increased flooding
The salt tolerant native tree population will continue to increase due to their adaptation

Many environmental advocates believe that biofuel made from palm oil is NOT an appropriate replacement for fossil fuels such as petroleum because ________. Many environmental advocates believe that biofuel made from palm oil is NOT an appropriate replacement for fossil fuels such as petroleum because ________. burning palm oil actually puts more carbon dioxide into the atmosphere than burning gasoline human rights are being violated because of the palm oil slave trade oil palm plantations take land away from coffee growers it is better to use palm oil in snack foods tropical forests must be cleared to plant oil palms
Answer:
tropical forests must be cleared to plant oil palms.
Explanation:
Renewable energy is also known as clean energy and it can be defined as a type of energy that are generated through natural sources or technology-based processes that are replenished constantly. Some examples of these natural sources are water (hydropower), wind (wind energy), sun (solar power), geothermal, biomass, waves etc.
Basically, a renewable energy source is sustainable and as such can not be exhausted.
Non-renewable energy refer to a type of energy that is generated through artificial sources or that cannot be replenished. It includes coal, natural gas, fossil fuels, petroleum
Many environmental advocates believe that biofuel made from palm oil is not an appropriate replacement for fossil fuels such as petroleum because tropical forests must be cleared to plant oil palms. Palm fruits are region selective plants and as such wouldn't didn't thrive in regions other than tropical forests.
