Answer:
If there was no system of lymphatic vessels, there would be no drainage of excess fluid from the tissues and the lymphatic fluid would accumulate in the tissues, causing them to swell.
Explanation:
The lymphatic vessel is made up of tiny vessels that are closed at one end and can be found in the spaces in the cells, except the central nervous system and the non-vascular tissues.
The main function of the lymphatic vessel is to move lymph which is a fluid that contains infection-fighting white blood cells to every part of the body.
So, if there was no system of lymphatic vessels, and tissue fluid was moved directly back into the circulatory system throughout the body. the lymphatic fluid would accumulate in the tissues, causing them to swell.

which of these changes in the food web would cause a decrease in the population of bald eagles
The correct answer is C. A decrease in the population of sea ducks
Explanation:
Food webs are diagrams that represent the relationship of organisms in an ecosystem by showing feeding or predatory relationships. This means food webs show which organisms eats another organism. In the case of the food web presented, this shows bald eagles fed on sea ducks and large piscivorous fish, this implies for survival bald eagles need from these two organisms. In this context, a decrease in the population of sea ducks (option C) would cause a decrease in the population of eagles because fewer sea ducks imply less food for eagles, and therefore fewer resources to survive.

Chloe is studying the effect a certain kind of fungus has on bacteria. Which of the following could be her hypothesis?
"I notice that when a certain fungus is present in a bacterial culture, the bacteria do not grow".
"Based on my tests, I realize that this fungus kills bacteria".
"I predict that the bacterial cultures in which I place this fungus will not grow".
"I propose that this fungus somehow kills bacteria."
Answer:
I propose that this fungus somehow kills bacteria
Explanation:
you rule out 2,3 because a hypotheses has not yet been proven therefore it is not certain
while in 1 in some cases the bacteria can also over power and kill the fungi using genes
but I chose 4 since fungi lack chloroplasts so they feed of ready made food and bacteria can be autotrophic therefore can manufacture food and so the fungi digests the bacteria in the process of trying to acquire the food since they don't have cell walls I guess

Thylakoids contain clusters of chlorophyll and proteins known as . They absorb sunlight and generate high-energy that pass along the .
Answer:
1) Photosystems
2) Thylakoid membrane
Explanation:
Photosynthesis is an important phenomenon for the cells of autotrophic organisms like green plants. It is the process through which they obtain their energy source. Photosynthesis, which consists of two stages, occurs in the Chloroplast of the cell.
The light dependent stage occurs in the thylakoid lumen of the CHLOROPLAST while the light independent stage occurs in the stroma. The thylakoid is a membrane-bound sac usually organized in stacks called GRANA.
The Chlorophyll pigment, which captures the photon of light needed for the photosynthetic process, is contained in the thylakoid. Also, embedded in the thylakoid space are protein complexes called PHOTOSYSTEMS, which are involved in the capturing photons of light and transferring of electrons. The Photosystems 1&2 are the functional units of photosynthesis.
The high energy generated by the Photosystems are transferred from one electron carrier to another along the thylakoid membrane in order to generate ATP and NADPH. This process is called Electron transport chain.
Thylakoids are the membrane-bound structures present within chloroplasts of the plant cell. Thylakoids consist of photosystems and are surrounded by the thylakoid membrane.
The correct blanks for the given statement are:
Thylakoids contain clusters of chlorophyll and proteins known as photosystems. They absorb sunlight and generate high energy that passes along the thylakoid membrane.
Photosystems in the thylakoids are the structural and functional protein complexes, which play a crucial role in performing photosynthesis. These systems are present along the thylakoid membranes, and carry out the primary photochemistry of photosynthesis.
The thylakoid membrane is involved in the light-dependent reactions of photosynthesis. The membrane absorbs light energy and is then converted into chemical energy. The high-energy generated is passed along the thylakoid membrane.
Therefore, the correct answers are photosystems and thylakoid membrane.

Why do you think the eukaryotic DNA requires multiple origins of replication?
A.
Multiple origins help make more copies of the same DNA simultaneously.
B.
Eukaryotic organisms have unique DNA strands for each specialized cell.
C.
Eukaryotes do not have topoisomerase, so multiple origins are created due to tension from unwinding of DNA strands.
D.
Eukaryotic DNA is much larger and replication at multiple origins helps reduce the time required for whole genomes to replicate.
E.
Multiple origins of replication ensure that there are no lagging strands and replication takes place at the same pace.
.
Answer:
D.
Explanation:
Prokaryotic DNA exhibit single origin of replication while eukaryotic DNA has multiple origins of replication because eukaryotic DNA is much larger and multiple origin of replicate helps them to replicate the whole genome in short time duration.
Large DNA of eukaryotes contain high amount of material to be replicated and multiple origin sites helps them to replicate in short time. DNA replication initiate at each origin site independentaly and terminate at corresponding termination sites.

Cocklebur will not flower if exposed to 8 hours of dark and 16 hours of light. It will flower if exposed to 16 hours of dark and 8 hours of light. However, if the 16 hours of dark is interrupted with a brief period of light the cocklebur will not flower. What triggers cocklebur to flower
Answer:
Photoperiodism
Explanation:
The process explained in the question is called "Photoperiodism" which refers to the plants' reaction to the length of the dark and light period in a day.
When the dark period is interrupted with a certain period of artificial lighting, the plant thinks that the day had a longer period where it's "light" than it is "dark" so it gets tricked into flowering. Same concept can be applied in reverse for the plants who flower during longer periods of dark.

The graphic shows the citric acid cycle. A diagram of the citric acid cycle is shown. Acetyl C o A enters the citric acid cycle and combines with a 4-carbon compound to form citric acid. During the citric acid cycle, what happens to acetyl-CoA? It enters the citric acid cycle and gains carbon dioxide to form citric acid, and gains more carbon dioxide through redox reactions to form a 4-carbon molecule. It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule. It enters glycolysis and associates with a 5-carbon molecule through redox reactions, forming another acetyl-CoA molecule. It enters the citric acid cycle and associates with a 4-carbon molecule, forming a 5-carbon compound, and then through oxidation reactions regenerates the 4-carbon molecule.
Answer:
It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.
Explanation:
Acetyl-CoA(2C) associates with oxalacetate(4C) to form citric acid(6C). Then through redox reactions, CO2 molecules result from decarboxylation (COOH becomes R-(R1)CH-R2). And through dehydrogenation H2 molecules are incorporated in NADH+ in FADH2, resulting in the 4-carbon molecule at the beginning (oxalacetate). That's why it's called a cycle(Kreb's cycle or citric acid cycle)
In the citric acid cycle, when acetyl-CoA enters the cycle, it associates with a 4-carbon molecule (Oxalacetate), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule (Oxalacetate).
--------------------
The resumed steps of the Citric acid cycle are as follows,
1) Acetyl CoA joins an oxaloacetate molecule, which is a 4C molecule. They release the CoA group and form a 6C molecule called Citrate.
Acetil CoA + Oxalacetato → Citrato + CoA group
2) Citrate turns into an isomere Isocitrate
3) Isocitrate oxidates and release 1 CO₂ molecule, producing an α- ketoglutarate molecule -this is a 5C molecule-. Meanwhile, NAD+ reduces to NADH.
Isocitrate + NAD+ → α-cetoglutarate + CO₂ + NADH
4) α-ketoglutarate oxidates and release 1 CO₂ molecule, producing a 4C molecule, which joins a Coenzyme A producing Succinyl-CoA. Meanwhile, NAD+ reduces to NADH.
α-cetoglutarate + NAD+ → 4C molecule + CO₂ + NADH
4C molecule + Coenzyme A → Succinil-CoA
5) CoA from Succinyl-CoA is substituted with a phosphate group, which then forms ATP. The final product is Succinate and ATP
Succinyl-CoA + Phosphate group + ADP → Succinate + ATP + CoA
6) Succinate oxidizes and forms Fumarate, a 4C molecule. FAD+ forms FAH₂
Succinate + FAD+ → Fumarate + FADH₂
7) A water molecule and Fumarate produce Malate, which is another 4C molecule
Fumarate + H₂O → Malate
8) Finally, malate oxidizes and oxalacetate regenerates -the initial 4C compound-. NAD+ reduces to NADH.
Malato + NAD+ → Oxalacetate + NADH
So, when acetyl-CoA enters the cycle, it associates with a 4-carbon molecule (Oxalacetate), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule (Oxalacetate).

This relative dating technique is based on the principle of Group of answer choices fluorine analysis. paleomagnetism. geolayering. superposition.
Answer:
superposition
Explanation:
Dating consists of ordering geological events according to the time they occurred, which ones occurred first, and which ones occurred latterly. This dating can be done by using the superposition geological principle.
Sediments can be incrusted in horizontal layers in the ground, called stratum. Different stratum can give us information about the environment in the past. They keep information about the age and the conditions under which the sediments got deposited.
Some geological principles allow us to date, relatively, the age of different geological events in the past.
Sediment layers place in a temporal sequence, let us know that the older layers are located in an inferior position concerning the newer layers. Hence, fossil species placed in more inferior layers are supposed to be older than fossil species found in more superficial layers.
