Cells are the smallest unit of life. This is true.

Cells are important to the structure and function of living things. This is true.

All organisms are made of multiple cells. This is false, because there are many single celled organisms like bacteria.

Cells come in different shapes and sizes. This is true, as there are cells with a variety of shape and size (round shaped cocci and the elongated and flat bacillus). There are cells from squid's nervous system, called the neurons, that are comparatively very large in size than the vast majority of the other cells.

The energy acquired in photosynthesis is used to make glucose. Where is the glucose made in plants?
klio [65]

Explanation:

<u>in the stroma</u>

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

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.

Occuring 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. 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; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain.
  • This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
  • Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules in the stroma. These store energy in their bonds, which can be released in respiration in the mitochondria.

During ______, the gravitational forces of the sun and moon pull on the Earth from the same direction, or opposite dire
STatiana [176]

Answer:

Spring Tides.

Explanation:

Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.

Generally, the gravitational pull of the Moon cause visible changes on planet Earth's surface.

This ultimately implies that, the pull of the Moon's gravity causes high and low tides on planet Earth's surface.

The various types of ocean tides based on the position of the Earth, Moon and the Sun are;

I. Neap tides.

II. Spring tides.

III. Low tide.

IV. High tide.

V. Brown tide.

VI. Rip tide.

VII. Red tide.

Do you think lava could have formed the channel on Mars? Why or why not?
shtirl [24]

Answer:

maybe but not probable

Explanation:

Larger image Flowing lava can carve or build paths very much like the riverbeds and canyons etched by water, and this probably explains at least one of the meandering channels on the surface of Mars. ... Lava is generally not thought to be able to create such finely crafted features.

Due to negative effects on blood lipids, partially hydrogenated oils, the main source of ______, have been banned from the food
kotykmax [81]

Due to negative effects on blood lipids, the main source of low density lipoprotein have been banned from the food supply.

<h3>What is Low density lipoprotein?</h3>

This is a type of molecule which comprises of lipid (fat) and protein and is regarded as bad cholesterol as it clogs the arteries.

This type of lipid increases the risk of heart disease which is why it was banned from the food supply.
