Answers
The properties of photosynthetic pigments that allow pigments to absorb light of only certain wavelength is ; ( B and D )
Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed.All pigment molecules possess a light-trapping region with a special structure that allows electrons to move freely between Its atoms.The Green pigment found in plants ( i.e. photosynthetic pigment ) that absorb light energy used by plants during photosynthesis is the chlorophyll. It absorbs light energy based on the wavelength of the visible light while reflecting visible green light due to its wavelength.
The reflection of the visible green light by the chlorophyll gives the plants leaves the green color it possesses.
Hence we can conclude that The property of photosynthetic pigments that allow pigments to absorb light of only certain wavelength is ; Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed. and statement D.

Yes
Explanation:
In the inner-world perspective of the simulation, the worm is absolutely alive as it is obeying the laws of physics as presented by the simulation.
I HOPE THIS HELPS!!!!!
Since it is adhering to the simulation's depiction of the rules of physics, the worm neurons appear to be completely alive from the simulation's inner-world perspective.
What is the worm?The worm is a frequently utilised organism in neuroscience research, because of the limited amount of neurons it contains For instance, the hermaphrodite form of the worm contains 302 neurons in its nervous system, as opposed to the 86 billion neurons found in humans.
Every animal requires a brain to survive, and worms are no different. Their brains control movement, sensory perception, and any other physical processes essential to their existence. A worm cannot, however, use its brain for thought.
Therefore, The worm neurons appear to be fully alive from the simulation's inner-world perspective because it is obeying the simulation's representation of the laws of physics.

Hey there the answer would be D. Keratin is the pigment responsable for skin color.
Explanation:
A. The top layer of the epidermus is made of dead skin cells. The inner player has to be constatnly making more cells
B.The body procudes more melanin with stronger sunlight exposure. This results because the UV of the sun causes T-T dimers which is a type of DNA damage.

D.Keratin is found in the epidermis and with thick layer of skin found in the hands and feet. Melainin is responsible for skin color.
What drives surface currents?
differences in air temperature
differences in climate
differences in water density
differences in water salinity
Answers
Answer:
WHAT DRIVES SURFACE CURRENTS?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.
DIFFERENCES IN AIR TEMPERATURE.
Movement of air due to differences in temperature between two locations is known as convection or advection. Convection is the term commonly applied to vertical movement of air, whilst advection is used in the context of horizontal displacement of air.
DIFFERENCES IN CLIMATE.
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
DIFFERENCES IN WATER DENSITY.
High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense. As it gets colder, it becomes denser. Most chemicals get denser when they turn from a liquid to a solid, but water is different.
DIFFERENCES IN WATER SALINITY.
As we have seen, most differences in salinity are due to variations in evaporation, precipitation, runoff, and ice cover. All of these process occur at the ocean surface, not at depth, so the most pronounced differences in salinity should be found in surface waters.

drag each micrograph to the target that indicates the stage of mitosis or cytokinesis it shows.
Answers
Mitosis occurs after the interphase and involves four stages. After mitosis event occurs cytokinesis. The correct order is 1A, 2F, 3E, 4B, 5C, 6D.
------------------------------------------
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
First occurs duplication of the cell content, and then the separation into two new cells happens.
Mitosis occurs in only one phase.
• In the prophase, it occurs chromosomes condensation and nuclear membrane breaks.
• During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.
Each chromatid joins with a microtubule of opposites poles.
• In Anaphase, bonds between chromatids break. They separate and migrate to the opposite poles.
• In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.
• Finally, cytokinesis occurs. Through invagination of the cell membrane, the cells and their cytoplasmatic content get separated.

what percentage of genetic information is passed on from parents to their offspring
Answers
Answer:
50% from each parent
Explanation:
The percentage of genetic information passed on from parents to their offspring is 50% from each parent, for a total of 100%.
What is the percentage of genetic information?Approximately 50% of genetic information is passed on from each biological parent to their offspring. This occurs through the combination of genetic material during fertilization, where half of the offspring's genetic material comes from the mother and the other half from the father.
However, the exact percentage of genetic information passed on can vary due to factors such as genetic mutations and recombination during meiosis.
This occurs through the process of sexual reproduction, where each parent contributes one gamete (sperm or egg) containing half of their genetic information.
When the sperm and egg combine during fertilization, they form a zygote with a complete set of genetic information (100%), half from each parent.

different photosynthetic pigments from a plant pigment extract can be separated by
Answers
The different photosynthetic plant pigments can be separated by PAPER CHROMATOGRAPHY. It is a methodology used to separate different chemical compounds based on their differential solubility.
This method (paper chromatography) uses paper sheets in order to separate mixtures of soluble substances such as, for example, plant pigments.
These paper sheets represent the 'stationary phase' through which a solution is made to pass.
Subsequently, during the mobile phase, the solvent moves through the paper sheet and thus carries (separates) different compounds with it.
