Charles Darwin observed the variation of organisms in the Galápagos Islands during his voyage on the HMS Beagle in 1835.

Charles Darwin's observations of the variation of organisms in the Galápagos Islands, greatly influenced his theory of evolution by natural selection. While exploring the various islands in the Galapagos, Darwin noticed that the animals and plants on each island had slight differences from the same species on other islands.

This led him to conclude that the differences were caused by the different environments on each island, and that this could lead to the evolution of new species over time. This observation was a major factor in the development of Darwin's theory of evolution by natural selection, which has since become one of the most widely accepted theories in the field of biology.

Answer:

carbon

Explanation:

Carbon forms bonds with other atoms which gives flexibility that biomolecules can use to make DNA and RNA causing to make the building blocks of life.

The resulting daughter cells are shown in the attached figure.

Stem cells have two chromosomes. One chromosome has C and D genes, while the other has c and d genes. Chromosomes are copied during the cell cycle's cell division cycle (interphase - S phase).

Chromosomes divide in meiosis I, resulting in the segregation of chromosomes.

During meiosis II, the two daughter cells resulting from meiosis-I are divided into four cells. The cells are separated resulting in the production of two types of gametes or daughter cells. One type contains the C and D genes, and the other type contains the c and d genes.

Through their stomata, plants transpire their water in the form of vapor or gas. Stomatal transpiration, or between 50 and 90 percent of all transpiration, loses the most water.

How do stomata respond to water status?

We still don't have a complete mechanistic knowledge of how stomatal responses to humidity, soil moisture, and other factors that affect plant water status affect photosynthesis, productivity, water production, ecohydrology, and climate forcing.  Here, I go over earlier and more current developments in stomatal water interactions. The synthesis of abscisic acid in leaves may play a role in the metabolically mediated response to leaf water status in stomatal responses to evaporative demand and soil drought.  Humidity, light, and temperature responses may also be influenced by additional speculative mechanisms involving vapor and heat transfer within leaves, although these mechanisms need more theoretical development and experimental verification..

Both types of protein can be produced by ribosomes, however, proteins that are destined to be secreted are often produced by ribosomes that are attached to the endoplasmic reticulum.

Cells determine which proteins are destined to stay within the cell and which are to be secreted through the use of a process called protein sorting. This process occurs during protein synthesis and involves the addition of specific signals or tags to the protein, such as a signal peptide or a transmembrane domain. These signals act as a sort of "address label" that directs the protein to its proper destination within the cell or out of the cell through the secretory pathway. Proteins that are not tagged for secretion will typically remain within the cell and may serve a variety of functions such as enzymes, structural proteins, or regulatory proteins.

Photosystem PS1 is a photosystem found in the thylakoid membranes of chloroplasts in plants and other photosynthetic organisms.

What exactly are photosynthetic organisms?

Photosynthetic organisms are organisms that can produce their own food through the process of photosynthesis. This process involves the use of light energy to convert carbon dioxide and water into glucose (sugar) and oxygen. Photosynthetic organisms include plants, algae, and some bacteria.

Photosystem PS1 is the primary photosystem in plants and other photosynthetic organisms. It is composed of two membrane-bound proteins, called photosystems, that contain light-harvesting complexes and a reaction center. The light-harvesting complexes absorb energy from sunlight and direct it to the reaction center, where it is used to produce ATP and NADPH, the molecules needed for photosynthesis. The products of photosystem PS1 are then used to drive the second photosystem, PS2, which produces the end products of photosynthesis.

The energy is released or absorbed by the reaction if the reactants of a certain chemical reaction contain 26 kJ of potential energy, and the products contain 41 kJ is 15kJ.

Potentiаl energy is the energy thаt is stored in аn object due to its position relаtive to some zero position. Аn object possesses grаvitаtionаl potentiаl energy if it is positioned аt а height аbove (or below) the zero height.

The maximum kinetic energy of the photoelectron K0 when light with a wavelength of 310 nm falls on the same surface is 2.135 eV.

You need to find a working function to solve this problem. Quantum Theory Regarding the Photoelectric Effect of the work function (eV), the work function describes the minimum energy required for electrons to continue to stick to the metal.

Planck's constant is also 4.14 x 10⁻¹⁵ eV.

Max KE = 1.10 eV

lambda = 400 nm = 400 x 10⁻⁹ m

First, find the frequency.

f = c ÷ λ

f = (3 x 10⁸) ÷ (400 x 10⁻⁹ m)

f = 7.5 x 10¹⁴

Max KE = hf - work function

1.10 eV = (4.14 x 10⁻¹⁵eV) (7.5 x 10¹⁴) - function

work function = 2.005 eV

Now find the frequency for the second wavelength.

f = c /λ

f = (3 x 10⁸) ÷ (300 x 10⁻⁹)

f = 1 x 10¹⁵

Now plug this into your equation with the frequency and work function you found in the previous problem.

KEmax = hf - work function

KEmax = (4.14 x 10⁻¹⁵ eV)(1 x 10¹⁵) - 2.005 eV

KEmax = 2.135 eV

So, the maximum kinetic energy is 2.005 eV
