Answers
Answer:
B. The reactions don't require light to be carried out.
Explanation:
Dark reaction is a light-independent process. This reaction occurs in the stroma of the chloroplast where it utilizes the products of the light reaction. Since this is not directly dependent on light, it is called as the dark reaction.
identify each of the relationship described below as Predation, Parasitism, Mutualism

Epiphytic ferns, which attach themselves to the trunks of large rainforest trees as a means of support.
Answers
Answer:
Commensalism
Explanation:
The trees are not being harmed by the ferns' attachment, but also do not gain anything from the relationship, The ferns gain a supportive, stable environment. Since one organism has a positive gain while the other has no advantage in the relationship, it is commensalism.
Commensalism is a type of relationship in which one organism benefits from the association, while the other organism is unaffected. In this case, the epiphytic ferns benefit from the support provided by the trees, while the trees are not affected by the presence of the ferns.

7. In the Everglades, a system of canals and levees diverts water to urban areas and the Everglades National Park. This water management system has caused changes in
natural flow of the water during the wet and dry season. Wading birds are especially sensitive to wet and dry seasonal changes. How have water cycle disruptions MOST
affected wading birds?
O The release of water dilutes food sources for their young.
O The higher water levels allow longer-legged birds to survive and reproduce.
O The water quality for feeding has been improved by runoff.
The reduced salinity results in more eggs being laid.
Answers
Answer:
Explanation:
The water cycle disruptions have most affected wading birds by:The release of water dilutes food sources for their young.This is because wading birds depend on the natural flow of water to bring in fish and other small aquatic organisms which are a vital part of their diet. When the water cycle is disrupted by the canals and levees, the water flow changes, and the amount and timing of these organisms can be impacted, making it harder for wading birds to find food for their young. Therefore, option (a) is the correct answer.Option (b) is incorrect because longer-legged birds are not necessarily more adapted to survive in higher water levels.Option (c) is incorrect because water quality may not necessarily improve due to runoff.Option (d) is incorrect because reduced salinity may not be a direct cause of increased egg-laying.

A. Strand 1 is the smallest.
B. Strand 2 is larger than strand 3
C. Strand 3 is larger than strand 4.
D. Strand 4 is the smallest
Answers
Answer:
A
Explanation:
Gel electrophoresis is an amazing technique that allows for DNA separation based on size (as in, length). Using electricity (and keeping in mind that DNA has a negative charge because of the phosphate groups), the shortest pieces will migrate the farthest.
So we can tell that the pieces are in ascending order of size. 4>3>2>1, in length.
A. Strand 1 is the smallest.
Answer:Given results of gel electrophoresis shows that strand 1 is smallest. The pieces are arranged in ascending order of size 4>3>2>1 . Thus,option A is correct.
Explanation:
What is Gel electrophoresis?
Gel electrophoresis is a laboratory technique used to separate mixture of DNA ,RNA or protein according to their molecular size.
The gel used in this technique is composed of polyacrylamide or agarose.
The main application of gel electrophoresis has been in the seperation of molecules and in restriction mapping.
The main advantage of gel electrophoresis is its capability to
simultaneously separate various samples in one round.
Therefore, strand 1 is the smallest according to the result of gel electrophoresis shown in figure. Thus, option A is correct.

30. What is the potential where a cell membrane must be more positive than negative to initiate an impulse?
A.action potential
B.stimulus
C.threshold potential
D.membrane potential
Answers
The threshold potential is the value at which a cell membrane must be more positively charged than negatively charged in order to produce an impulse.
Threshold potentialThe threshold potential is a crucial depolarization level that must be attained in order for a neuron to initiate an action potential or nerve impulse.
Voltage-gated ion channels in the membrane of a neuron open when the membrane potential reaches the threshold potential, enabling an influx of positively charged ions into the cell.
The result is a fast depolarization of the cell membrane, which generates an action potential that travels the entire length of the neuron.
It's crucial to understand that the threshold potential varies depending on the kind and location of the neuron, in addition to other elements like temperature and the presence of toxins or medications.

Does the pharynx of human respiratory system have cartilage and epithelium?
Answers
Answer:
There is no cartilage but there is epithelium
Explanation:
The pharynx of the human respiratory system does not contain cartilage.
The pharynx, part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for air and food. The gorge is made up of several regions, each with its own distinctive features.
The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.
These regions also lack cartilage but are lined with stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.

"True statement" or the first option.
The Earth is purely powered on solar energy and depending on how much of the suns energy is in the Earth's system varies the climate. One of the most common examples of this are deserts. During the day in a desert, it is very hot and humid because the sun is giving off its energy which is heating up the sand making the area much warmer. When it's night it gets pretty cold, because the sun is no longer out giving off its energy in that area and is now cooling off.

Which of the following processes releases carbon into the air? (5 points)
Answers
Answer:
Explanation:
Combustion of fossil fuels: Burning coal, oil, and natural gas to produce energy releases carbon dioxide (CO2) into the atmosphere.
Other processes that can release carbon into the air include:
Deforestation: Trees absorb carbon dioxide through photosynthesis, and cutting down forests can release the carbon stored in the trees and soil.
Volcanic activity: Volcanic eruptions can release carbon dioxide and other greenhouse gases into the atmosphere.
Decomposition: When organic matter such as plants, animals, and other living organisms decompose, they release carbon dioxide and other gases into the atmosphere.
Ocean outgassing: The ocean absorbs and releases carbon dioxide as part of its natural cycles, and some of this carbon can be released into the air.
It's important to note that while some of these processes are natural, human activities such as burning fossil fuels and deforestation have significantly increased the amount of carbon dioxide in the atmosphere, leading to climate change.
