Answer:
Flat discs inside chloroplasts that are arranged in stacks are called (2) __thylakoids_. (3) __Pigments__ are light-absorbing substances that are inside chloroplasts. They absorb light of different (4) __wavelenghs__. The green pigment in plants that is essential for photosynthesis is (5) __Chlorophyll __. Light energy absorbed by this pigment excites (6) ____electrons___. They are transferred to a(n) (7) _Electron Carrier_. Then they move down an electron transport chain.
Explanation:
The chloroplasts are limited by an outer membrane and an inner one. In the middle of the two membranes, there is a space left called intermembrane space. In the interior of the inner membrane, there is another space known as the stroma. Within the stroma, there is the third system of membranes, known as thylakoids. They are disk-shaped structures, limited by a membrane, and in their interior, there is a space named thylakoid space.
Thylakoids are arranged as piles, receiving the name of grana. Grana connect to each other by a longer thylakoid membrane. The photosynthetic pigments are placed in the thylakoids, where it occurs light-dependent reactions. These molecules are in charge of light absorption. The most common pigment is chlorophyll, which provides the typical green color of plants. When sunlight reaches the pigments, electrons get excited and move along the electron transport chain, places in the thylakoid membrane. This process occurs during photosynthesis, while new electrons provided by water molecules replace the excited ones. The final products are oxygen, ATP, and NADPH.
In the stroma, it takes a place the Calvin cycle.

The endosymbiosis hypothesis is supported by all of the following pieces of evidence except the fact that Group of answer choices chloroplasts reproduce through a splitting process like certain prokaryotes. mitochondria have circular DNA like prokaryotes. chloroplasts have ribosomes like prokaryotes. mitochondria lack ribosomes like prokaryotes.
Answer:
The correct answer is - mitochondria lack ribosomes like prokaryotes.
Explanation:
The Endosymbiotic Theory says that mitochondria and chloroplast in eukaryotic cells are developed by the once aerobic bacteria that were engulfed by a large anaerobic bacteria.
This theory suggests the origin of eukaryotic cells. Various evidence exists such as mitochondria and chloroplasts contain their own circular DNA like prokaryotic cells and mitochondria and chloroplasts have 70S ribosomes like prokaryotes have.
what is the meaning of respiration
Answer:
in physiology respiration is the movement of oxygen from the outside environment to the cells with tissues and the removal of carbon dioxide in the opposite direction .. in contrast exhalation is usually a passive process
hope it's helpful
Answer:
The process of breathing.
Explanation:
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
**Physiological respiration and cellular respiration are not the same. People sometimes use the word "respiration" to refer to the process of cellular respiration, which is a cellular process in which carbohydrates are converted into energy. The two are related processes, but they are not the same.

The rocky material left behind by a retreating glacier forms what is called a moraine. When primary succession occurs on a moraine, which life-forms will help create the soil by breaking down bare rock?
A Insects
B Lichens
C Grasses
D Deciduous trees
Answer:
The correct answer is - B. Lichens.
Explanation:
Lichens are one of the pioneer species that can grow on bare rock such as moraine and help make soil for further ecological succession and making ground for other species.
Breaking the bare rocks to convert into the soil is part of the primary succession. Lichens are colonized over these rocks and they contain acid which leads to the breakdown of the moraine and other rocks.
It is often difficult to save individual species
this is true, but where is the problem? or do i just not see it?

A sponge actually feeds by
a. acting as a net in a current that sweeps food particles through it.
b. squeezing the spongocoel cavity and sucking debris in and out through the osculum.
c. the beating of the flagella of collar cells, forming a current; food is absorbed by collar cells.
d. the beating collar cells form a current from osculum to pores; the food is engulfed by amoebocytes in the central cavity of the sponge.
e. water the moves gently through the sponge and the amoebocytes that engulf passing food.
Answer:
c. the beating of the flagella of collar cells, forming a current; food is absorbed by collar cells.
Explanation:
Sponges contains the unique feeding system that should be with the animals. Rather of mouths they have the tiny pores that we called as the ostia displayed on the outer walls via water is drawn. Here cells in the sponge walls strainer the food from the water because the water is pumped via the body and the little mouth
So as per the given options, the option c is correct as the collar cells would create the current and the food should be absorbed by the collar cells

How do white blood cells protect the body against infections
Answer:
White blood cells, which are also called leukocytes or white corpuscles, are a cellular blood component that does not include hemoglobin, have a nucleus, are motile, and protect the body from infections and diseases through ingestion of foreign materials and cellular debris, destruction of infectious agents and cancer cells or production of antimicrobials.
Explanation:
There are 4,500 to 11,000 cells in the white blood of a healthy adult person per cubic mm of blood. During the day, fluctuations in the number of white cells take place; lower values during rest and higher during exercise are attained. The quantity of white cells increases abnormally, while the number decreases abnormally, Leukopenia.
Intensive physical activity, seizures, extreme emotional response, pain, pregnancy, labor, and specific conditions such as infections and intoxications may increase the counting of white cells. In reaction to some types of infections or medication, or in conjunction with certain illnesses such as chronic anemia, malnutrition, or allergy, the number may drop.
Explain the process in which hormones secreted by the pancreas function with respect to increased glucose levels in the blood
Answer:
Gastrin: This hormone aids digestion by stimulating certain cells in the stomach to produce acid. Glucagon: Glucagon helps insulin maintain normal blood glucose by working in the opposite way of insulin. It stimulates your cells to release glucose, and this raises your blood glucose levels.
