When meiosis is complete, what has been produced?

The human body has about 10 bacterial cells for every eukaryotic cell. Bacteria coat our skin, gut, and mouth. Also present are

madreJ [45]

Answer:

can be mutualistic or antagonistic.

Explanation:

According to the given information, the bacterial species Staphylococcus aureus present in some nasal passages and on the skin do not harm the person. The ecological interaction wherein both organisms are benefited and none is harmed is known as mutualism. Here, Staphylococcus aureus does not cause any disease in human when present on the skin and in the nasal passage, that is both are in mutualism.

However, when present in the bloodstream, the same bacterial species can cause infections such as sepsis and represents antagonist effects on the host.

Hence, the staphylococcus aureus species may be mutualistic or antagonistic to human.

What distinguishes disruptive and directional selection pressures when both select for extreme genetic traits?

Stella [2.4K]

Answer:

Yes both are different. In directional selection one of the extreme traits is favored, whereas in disruptive selection both the extreme traits are favored.

Explanation:

Directional: If selection acts to eliminate one extreme form and supports the other extreme then the peak shifts in the direction which is selected by the nature.

Disruptive: If the selection does not favor the mean character value, rather favors both the peripheral character values then this kind of selection is called disruptive selection.

Put these steps in the order in which they occur in light-dependent reactions. Electrons are transferred from photosystem II to

Tamiku [17]

Explanation:

Light energy is absorbed and transferred to the reaction center.
A water molecule is split.
Electrons are transferred from photosystem II to photosystem I.
ATP is synthesized from ADP and inorganic phosphate.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

The chloroplast is a membrane bound organelle found in plants. It contains several invaginations of a plasma membrane called the thylakoid membrane. This contains chlorophyll pigments, in stacks called granum, while the internal spaces of the organelle are called the lumen. Liquid surrounds the granum, forming the stroma.

During the light reaction:

Light is absorbed by pigments in phosystem II (PSII). This energy is transferred among pigments til it gets to the reaction center, and is transferred to P680; this promotes an electron to a higher energy level where it then goes to an acceptor molecule.

Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent.
the electron moves down an electron transport chain (ti PS I)where it experiences continuous energy loss. This energy fuels the pumping of H+ from the stroma to thykaloid, leading to the formation of a gradient. The H+ move along their gradient and cross through ATP synthase, into the the stroma.
ATP synthase converts ADP and Pi to the energy storage molecule ATP.
The electron gets to photosystem I where it goes to pigments at P700. It absorbs light energy, the electron is promoted to a higher energy level, and passed to an electron acceptor. This leaves a space for another electron which is then replaced by one from photosystem II.
in the ETC, the molecule NADP is reduced to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.

Do you think molecules are larger or smaller than a cell in the human body?

JulsSmile [24]

Answer:

Yet you can turn up the magnification for an even closer look: Cells contain molecules that are made up of even smaller components called atoms. Figure 1: Levels of the body from smallest to largest: Atoms, molecules, cells, tissues, organs, and organ systems.
