What does polar ice do to much of the incoming sunlight?
Answer:
Arctic sea ice keeps the polar regions cool and helps moderate global climate. Sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. As sea ice melts in the summer, it exposes the dark ocean surface.
Explanation:
The English moth, Biston betularia, is often cited as an example of observed evolution. There are two colors of this moth, light and
dark (typica and carbonaria). Kettlewell found that dark moths constituted less than 2% of the population prior to 1848. Then, the
frequency of the dark coloration began to increase. By 1898, the 95% of the moths in Manchester and other highly industrialized
areas were of the dark color. Using the moth example, analyze the events in order to identify support for the statement: natural
selection changes populations, not individuals. Choose ALL that apply.
A)
Variation in the population existed.
B)
Color variation is a result of different gene combinations.
C)
In response to environmental change, moth coloration changed from light
to dark.
D)
Due to natural selection, the ratio of different genetic combinations is
changing
E)
Predator pressure resulted in the light colored genotype being removed
from the gene pool.
Answer:
A,B,C,F
Explanation:
A, B, C and D all of these statements support the idea that natural selection changes populations, not individuals.
What is natural selection?Natural selection is a process by which organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to their offspring. This leads to changes in the genetic makeup of a population over time, as advantageous traits become more common and less advantageous traits become less common.
Natural selection is driven by environmental pressures, such as predators, competition for resources, or changes in climate. It is a key mechanism of evolution, and helps to explain the diversity of life on Earth and the ways in which different species have adapted to their environments.

At which time of year would mitosis in a plant occur most frequently? Explain why?
Answer:
it would be based on the most common prophase time of year is.
Explanation:
I don't know to be honest.
In plants, mitosis occurs most frequently during the periods of growth such as the during the periods of inactivity such as during germination and springtime bud formation.
What is Mitosis?Mitosis is the cell division which occurs in all the somatic cells in the plant body as well as in the animal cell. Mitosis results into the formation of diploid cells.
Mitosis occurs most rapidly in the meristematic tissues of the plants. These are the zones of growth in plants.
In plants, mitosis occurs most frequently during the periods of growth, for example when they come out of the periods of inactivity, such as during seed germination and spring time bud formation.

Your neighbor, Mr. Turner, doesn't think that alternative energy resources like water, wind, or solar are important. He asks, "Why not just do what we have always done?" To help Mr. Turner understand, justify the use of alternative energy resources instead of fossil fuels with at least one real life example.
please help
Answer:
--
One of the amazing things about alternative energy resources is that they are renewable, unlike fossil fuels. The use of fossil fuels, such as coal and natural gasses, can contribute a lot to pollution since fossil fuels are usually processed through factories and plants. With water, wind, and solar energy, it is much easier to gain electricity with those methods rather than others, and much cheaper.

Explanation:
what are the two phases of the respiratory movement of man? Are they the same in a grasshopper or a fish?
The two phases of the respiratory movement of man is inspiration ( or inhalation) and expiration (or exhalation). The phases of the respiratory movement of men is the same in fish because they also inhale and exhale.
What is inspiration (inhalation ) ?
Inspiration (inhalation) is the process of taking air into the lungs. It is the active phase of ventilation because it is the result of muscle contraction.
What is expiration (exhalation)?
Expiration (exhalation) is the process of letting air out of the lungs during the breathing cycle.

b. The gastrodermis is associated with movement of cnidarians.
c. The epidermis contains various cell types and develops from the endoderm during development.
d. The epidermis is associated with sensing the environment and prey capture.
Answer:
a. The gastrodermis contains various cell types and develops from the endoderm during development.
d. The epidermis is associated with sensing the environment and prey capture.
Explanation:
Most cnidarians have two layers of cells organized into some luck of tissues that have specific functions.
Cnidarians' body organization is simple: It is a hollow structure composed of two cellular layers: epidermis, which is the external layer, and gastrodermis that is the internal layer, formed by lining cells in the gastrovascular cavity. Between these two layers, place the mesoglea that varies from a thin non-cellular membrane to a mucous, fibrous, thick membrane with amebocytes.
Epidermis and gastrodermis originate from two embryonic tissues, the ectoderm, and the endoderm, respectively.
The epidermis has five types of cells with different functions: epitheliomuscular, interstitial, cnidoblasts, secretors, and sensorial.
Gastrodermis is composed of cells such as nutritive cells, glandular enzymatic cells, secretory cells, and sensory cells.
What the consequences would be if the entire water surface was covered with water lilies
Answer: There can be a ton of damage done if water lilies overgrow.
Explanation:
Water lilies protect the organisms under the body of water and provide shade to the plants and organisms underneath. These are very important for organisms, as they also provide a place to rest. But if the entire water surface were to be covered with water lilies, this would be a major problem, because sunlight would have no way of reaching below the surface, and this would decrease oxygen levels for plants and organisms. Without air and sunlight, plants will start to die and organisms of the body of water will also start to die because of no air to breathe. Also, overgrowth of water lilies causes water stagnation and leads to excessive algae blooms. The stagnant water attracts insects like mosquitoes, cockroaches, termites, and more pests which can harm plants and organisms.

Early genetic manipulation of petunias included an attempt to engineer dark purple petals. To this end, extra copies of the gene that causes purple pigment was engineered to be produced in the petunia. However, to the surprise of many, the plants carrying the extra copies of the purple gene were completely white or only had patches of color. Molecular analysis revealed that the purple gene was reduced 50-fold in the engineered plants compared to wild type. Provide a possible explanation how this occurred. Also, provide a possible experiment that may overcome this setback
Answer:
The altered pigmentation in transgenic petunia plants is caused by the RNA interference (RNAi) mechanism
Explanation:
The RNA interference mechanism is a naturally occurring mechanism by which single-stranded RNA molecules can bind to complementary mRNAs in order to inhibit gene expression, blocking translation and leading to mRNA degradation. The example above described is a classical genetic experiment (Napoli et al. 1990 ) that showed the existence of the RNAi pathway by the overexpression of a chimeric chalcone synthase (CHS) gene in pigmented petunia flowers, which blocked anthocyanin biosynthesis. In this experiment, irregularly bicolored/white flowers in transgenic petunias containing exogenous pigmentation genes were developed. The co‑suppression of gene expression was produced by the high-copy-number transcription of the CHS transgene, showing the existence of an undescribed RNAi silencing mechanism. Somatic reversion of the altered phenotype can be achieved by restoring the normal mRNA levels for these pigmentation genes, e.g., by a progeny testing in order to eliminate transgenic CHS expression.
