Answer:
Explanation:
Photosynthesis is the process by which green plants synthesize their food from carbon dioxide and water by using the green pigment chlorophyll generating oxygen as product.
Chlorophyll "a " absorbs light from the orange-red and violet-blue areas of the Electromagnetic spectrum. Also Chlorophyll a transfers energy to the reaction center and donates two excited electrons to the electron transport chain
Its main role is as a primary electron donor in the electron transport chain. So the energy from the sun will ultimately become chemical energy that can be used by the plant for cellular processes.
Chlorophyll "b" absorbs blue light. The main role is to expand the absorption spectrum of organisms.
Plant can absorb more energy from the high frequency blue light part of the spectrum. Its presence in cells helps plant convert a wider range of the energy from the sun into chemical energy.
Carotenoids are usually red, orange, or yellow pigments, and include the compound carotene. These compounds are composed of two small six-carbon rings that are connected by a "chain" of carbon atoms. As a result, they do not dissolve in water, and must be attached to membranes within the cell. Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway, but must pass their absorbed energy to chlorophyll. For this reason, they are called accessory pigments.
Answer:
The presence of chlorophyll a, chlorophyll b, and carotenoids in chloroplasts allow plants to absorb more energy from sunlight by absorbing multiple wavelengths. Chlorophyll a absorbs blue-violet light and red light. Chlorophyll b absorbs mostly blue light. Carotenoids absorb violet, blue, and blue-green light. The pigments together, therefore, are able to absorb a wider range of wavelengths.

What is the relationship between air pressure and wind?
Answer:
Wind is air pressure converted into movement of air. When air slows down, its pressure increases. The kinetic energy or momentum of a moving air mass is converted in static atmospheric pressure as the air mass slows down. This means that higher wind speeds will show lower air pressure readings.
Answer: As the Sun unevenly heats the surface of the Earth, air rises and sinks, resulting in high and low regions of air pressure. As air rises, the pressure lowers and surrounding air moves in to replace it, causing wind. The more the pressure changes over a given distance, usually the faster the wind will be.

We're surrounded by living creatures that we can't see. What are some ways that tiny living things can affect your life, health or environment? Bacteria are tiny
Answer:
Microorganisms that are not visible are so called because their measurements are in micrometers and even nanometers.
We usually talk about viruses, bacteria, fungi and even parasites.
Explanation:
Microorganisms are mostly pathogens for humans, but others make up the commensal biota of the same living being.
Not all microorganisms need the same means to live and develop as large organisms such as those that are simple to the human eye.
Some microorganisms are seen by optical microooscopy and others smaller by electronically.
i have to write an Ocean Observation Method Paragraph can some one help me please?
Answer:
Changes in marine biodiversity—the variety and variability of life in the ocean—can be an early indicator of change, provided it's noticed. The U.S. Marine Biodiversity Observation Network (MBON) aims to ensure that scientists not only notice changes in biodiversity at locations around the nation, but also have the tools in place to better understand what these changes tell us about ocean health over time. But marine life doesn't know borders. That's why the U.S. network also supports international cooperation with other marine biodiversity networks, research institutions, governmental and non-governmental organizations and stakeholders around the world towards development of a truly

Which statements concerning the characteristics of water are correct? Choose all that apply.
A Water releases heat when it evaporates
B The solid form of water floats in the liquid form of water
C Water is a nonpolar substances
D Water is cohesive and adhesive allowing for hydrogen bonding
E The pH of pure water is 8
Answer:
water in non-polar
Explanation:
Explantion:
Nonpolar Covalent Bond. A bond between 2 nonmetal atoms that have the same electronegativity and therefore have equal sharing of the bonding electron pair. Example: In H-H each H atom has an electronegativity value of 2.1, therefore the covalent bond between them is considered nonpolar.
which cell cycle does cyclin production begin
Answer:
it begins on the cell cycle
Explanation:
Accordingly, cells synthesize G1- and G1/S-cyclins at different times during the G1 phase, and they produce M-cyclin molecules during the G2 phase. Cyclin degradation is equally important for progression through the cell cycle.

sixth mass extinction.
What evidence do we have that we are losing species at more than the normal rate?
Answer:
Most ecologists believe that we are in the midst of the sixth mass extinction. Humanity’s impact on nature, they say, is now comparable to the five previous catastrophic events over the past 600 million years, during which up to 95 percent of the planet’s species disappeared. We may very well be. But recent studies have cited extinction rates that are extremely fuzzy and vary wildly.

A molecule has been isolated from a cell. The molecule's structure has a three dimensional shape and is made of folded chains of amino acids. The function of this molecule is enzymatic catalysis of glycolysis. An analysis of this molecule would show that it contains which of these elements that would NOT be found in carbohydrates? A) carbon B) nitrogen C) oxygen D) phosphorus E) sulfur
Answer:
B) nitrogen
Explanation:
According to this question, a molecule which has been isolated from a cell has a three dimensional shape made of folded chains of amino acids. The molecule functions in the enzymatic catalysis of glycolysis. Based on the description of this molecule, it can be determined that it is a PROTEIN.
This is because PROTEINS are the biomolecules that are composed of amino acids monomers. The three dimensional shape of the molecule represents the protein at the TERTIARY LEVEL. However, in the structure of the amino acids, which forms the protein molecule, a central carbon is attached to a carboxyl group (-COOH), an anime group (-NH2) and a R side chain.
The protein molecule, therefore, contains NITROGEN element, which cannot be found in carbohydrates (made up of only carbon, hydrogen and oxygen).
An analysis of this molecule (protein) would show that it contains this chemical element that would not be found in carbohydrates: B) nitrogen.
A molecule with a three (3) dimensional shape and comprises folded chains of amino acids describes a protein.
Also, one of the function of protein is the enzymatic catalysis of glycolysis.
Generally, protein is a macromolecule which is formed as a result of the union of many folded chains of amino acids.
The molecular structure of protein is made up of the following:
A carboxyl group (COOH).An anime group (NH2).A R-side chain.In conclusion, an analysis of protein would show that it contains nitrogen which would not be found in carbohydrates.

Explanation:
Joanna read that certain perfumes would cause bees to leave the hive and act in an agitated fashion. She decided to investigate the response of bees to five different perfumes- Ralph Lauren, Armani, Mark Jacobs, Vera Wang, and the last is an odorless liquid. She placed a saucer containing 20ml of perfume A 10 meters from a beehive. She then recorded the total number of bees that emerged from the hive during a 15 minute interval and made observations on their behavior. Using a 30 minute interval between tests to allow recovery time for the bees, she then repeated the procedure to test the remaining three samples. Each test was conducted on the same day with similar weather conditions. whats the independent variable
Answer:
PERFUME
Explanation:
In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter in order to effect a measurable response in the dependent variable.
In this experiment, Johanna is trying to investigate the response of bees to five different perfumes- Ralph Lauren, Armani, Mark Jacobs, Vera Wang, and an odorless liquid, which is the control. Hence, the PERFUME is the independent variable because it is the manipulated variable.
