Answer:

One parent is needed

The sum total of an organism's interaction with the biotic and abiotic resources of its environment is called its A) habitat. B)
ivanzaharov [21]

Answer:

E) ecological niche

Explanation:

Every species on the planet, be it a bacteria, animal, or a plant has its own ecological niche. Basically, the ecological niche is the position and role that an organism is occupying in the environment. Further, this means that it is a combination of all the activities of the organism, how it uses the biotic and abiotic factors in the environment it leaves, how it finds food and how it feeds, its shelter, reproduction, the manner in which it survives. All of that sums up the species and its role in the environment, thus its ecological niche. There are countless ecological niches, as there are millions of different species, all of which have their own way of living, feeding, reproducing, interactions with the biotic and abiotic factors, resulting in numerous unique ecological niches.

List what Eukaryotic cells and prokaryotic cells have.
wolverine [178]

Answer:

Summary

All cells have a plasma membrane, ribosomes, cytoplasm, and DNA.

Prokaryotic cells lack a nucleus and membrane-bound structures.

Eukaryotic cells have a nucleus and membrane-bound structures called organelles.

Explanation:

Eukaryotic Cells

Eukaryotic cells usually have multiple chromosomes, composed of DNA and protein. Some eukaryotic species have just a few chromosomes, others have close to 100 or more. These chromosomes are protected within the nucleus. In addition to a nucleus, eukaryotic cells include other membrane-bound structures called organelles. Organelles allow eukaryotic cells to be more specialized than prokaryotic cells. below are the organelles of eukaryotic cells , including the mitochondria, endoplasmic reticulum, and Golgi apparatus.

Prokaryotic cells are usually smaller and simpler than eukaryotic cells. They do not have a nucleus or other membrane-bound organelles. In prokaryotic cells, the DNA, or genetic material, forms a single large circle that coils up on itself. The DNA is located in the main part of the cell.

Although the direct reduction of CoQ to CoQH2 is thermodynamically possible, this reaction is not a direct part of the electron
Nady [450]

Answer:

This electron handoff from NADH to FMN, as opposed to direct reduction of CoQ by NADH, a critical component of the electron transport chain is important for Signaling Transduction and Metabolomics

Explanation:

The NADH-CoQ reductase reaction is catalyzed by Complex I. In this course of activity, following events takes place-  

a) FNM (NADH dehydrogenase flavoprotein) is reduced by the NADH  to FMNH2 through following reactions –  

NADH+H++E-FMN↔NAD++E-FMNH2

b) In the next phase coenzyme Q  receives electron from FMNH2  through the the iron–sulfur centers of the NADH-CoQ reductase

c) The iron atom undergoes oxidation–reduction cycles to conserve  mitochondrial protein  as lataxin and hence transport protons from the matrix to the intermembranal space thereby Signaling Transduction and Metabolomics

Nearby stellar neighbors include the Alpha Centauri group and the Sirius star systems. Whereas light from our sun takes a little
goldenfox [79]

Answer:

The light from Alpha Centauri system takes 4.37 light-years and  Sirius star system takes 8.6 light-years to reach the Earth.

Explanation:

Light from millions of stars in more distant galaxies takes a long time to reach the Earth. Light travels at a speed of 300,000 kilometers per second. The time taken for light from these stars to reach the Earth is the distance to the star divided by the speed of the light. The distance traveled by light in one year is known as a light year and the distance to the stars that are farther away is expressed in light years.

The Sun is the closest star to the Earth and the sunlight takes about 8.3 minutes to reach on Earth. Apart from the Sun, the other stars closest to Sun include Alpha Centauri system and the Sirius star systems.

The Alpha  Centauri system includes the stars Alpha Centauri A, Alpha Centauri B and Proxima Centauri. This system is 4.37 light-years away from the Earth. The third star, Proxima Centauri is 4.24 light-years away from the Earth i.e., the light from it takes 4.24 years to reach the Earth.

The Sirius star systems include Sirius A (Dog Star) and Sirius B. It is about 8.6 light years from Earth and so the light about 8.6 years to reach the Earth.

How does the gravitational force of the moon affect Earth? (1 point)
padilas [110]

Answer:

B

Explanation:

High and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
