Just like vertebrate animals, plants possess excretory systems. One way that plants excrete waste products is by opening pores in the surfaces of their leaves. These pores, called stomata, help a plant maintain homeostasis by allowing the plant to
A.
release substances, such as oxygen and water.
B.
collect substances, such as ammonia and salt.
C.
destroy substances, such as sap and uric acid.
D.
make substances, such as chlorophyll and resin.
Answers
Stomata are pores on the leaves' surfaces that allows CO₂ entrance, while O₂ and water leave the plant. Option A is correct. Release substances, such as oxygen and water.
What are stomata?
Stomata are pores on the leaf's surfaces, surrounded by two kidney-like guard cells, which regulate their opening.
Guard cells can expand or contract according to the plants' needs, causing the stomata to open or close.
These pores allow gas interchange and water expelling. Stomata opening and closure depend on water and CO₂ concentration inside the plant.
If the plant is dehydrated, the stomata close. If it is not dehydrated, it opens.If CO₂ levels are too low, stomata open to gain it.
Stomata action is closely related to photosynthesis by controlling gas interchange -CO₂ and O₂-, and cell transpiration -water release-.
Gas interchange occurs when CO₂ moves into the leave cells through opened stomata. This gas is used during the light-independent reactions of photosynthesis (The Calvin cycle). Meanwhile, during the light-dependent reactions, O₂ is released and moves out of the plant through opened stomata.
Water balance occurs when stomata regulate water motion through transpiration. If the plant is dehydrated or climatic conditions are hot and dry, the plant limits water exit by closing its stomata. In this way, more water is available for the plant to photosynthesize under unfavorable situations.
Among the options, A is the correct one. Release substances, such as oxygen and water.

Answers
Answer:
So, I don't actually know what cells do this but if you want to think about like traits, scientists believe that it stems from their poor diet of just bamboo and lack of diversity in vegetation. Also, they don't hibernate and they move through different regions throughout the year. Because of this, they have adapted to be camouflaged in those environments at once (and all year round). Studies have shown that other than camouflage, their coloration also helps with communication. It is believed that the black on their ears is a warning to predators and their eye patches are for recognition or possibly aggressive signals.
To digest or breakdown a carbohydrate what process needs to take place and what happens during that process?
Answers
Carbohydrate digestion begins in the mouth. The salivary glands in the mouth secrete saliva, which helps to moisten the food. The food is then chewed while the salivary glands also release the enzyme salivary amylase, which begins the process of breaking down the polysaccharides in the carbohydrate food.
#SPJ1
Starches and sugars are mechanically and chemically broken down into the single units glucose, fructose, and/or galactose during digestion. These single units are then absorbed into the blood stream and transported to be used as energy throughout the body.
What is carbohydrate metabolism?The entire set of biochemical procedures involved in the metabolic synthesis, disintegration, and interconversion of carbs in living things is known as carbohydrate metabolism. Many vital metabolic pathways depend on carbohydrates.
Dietary glucose can either be processed through glycolysis or glycogenesis.
The resulting metabolic byproducts can either go on in carbohydrate metabolism to the citric acid cycle or return to glucose via gluconeogenesis or glycogenolysis, respectively.
Carbohydrates are broken down during digestion to produce ATP, a molecule that is high in energy.
The oxidation of glucose molecules results in the creation of ATP. To lower NAD+ and FAD, an electron is taken from a glucose molecule during oxidation.
Thus, this way, breakdown of a carbohydrate takes place.

Plants as well as brown, green, and red algae show a basic life cycle which involves the alternation of generations between a(n) egg and a sperm. seed and a cone. spore and pollen. megaspore and a microspore. sporophyte and a gametophyte.
Answers
Answer:
The correct answer is ''sporophyte and a gametophyte''
Explanation:
Plants have a diplohaplon life cycle: a haploid adult plant, called a gametophyte, and a diploid adult plant, called a sporophyte. In green algae, the two generations, sporophyte and gametophyte, are independent and generally the same size. This type of life cycle is found not only in many multicellular green algae, but also in brown algae and red algae. In vascular seedless plants, including ferns, gametophytes, although still independent, are smaller in size than sporophytes. In seed plants, the gametophytic generation is further reduced and is totally dependent on the sporophyte.

Explain why inmates who have been in the dark cell for quite long usually have problems with their eyes and usually squint when in bright light?
Answers
Answer:
No one can see in total darkness. Fortunately, there’s almost always some light available. Even if it’s only dim starlight, that’s enough for your eyes to detect. What’s truly amazing is how little light is required for you to see.
Human eyes have two main features that help us see better in low light: the pupil’s ability to change size, and the eye’s two types of light-sensing cells.
Opening up to let in more light
Your pupils are the black areas at the front of your eyes that let light enter. They look black because the light that reaches them is absorbed inside the eyeball. It’s then converted by your brain into your perceptions of the world.
You’ve probably noticed that pupils can change size in response to light. Outside on a bright sunny day, your pupils become very small. This lets less light into the eye since there’s plenty available

Explain what traits you would give a pathogen if you wanted to make it hard for a vaccine to be used. List at least 4 things help please
Answers
Answer:
Here are four traits that would make it hard for a vaccine to be used:
1. Rapid mutation rate. If a pathogen mutates rapidly, it will be able to evade the immune system's defenses, including the antibodies produced by a vaccine. This is a particular problem with viruses, which can mutate very quickly.
2. Ability to evade the immune system. Some pathogens are able to evade the immune system by hiding inside cells or by changing their surface proteins so that they are no longer recognized by the immune system. This makes it difficult for the immune system to mount an effective response to the infection.
3. Ability to spread easily. If a pathogen is easily spread from person to person, it will be more difficult to prevent infection through vaccination. This is a particular problem with respiratory viruses, which can be spread through coughing and sneezing.
4. Lack of animal reservoirs. If a pathogen does not have animal reservoirs, it will be more difficult to develop a vaccine against it. This is because vaccines are typically developed using weakened or killed versions of the pathogen. If there are no animal reservoirs, there will be no source of the pathogen to use for vaccine development.
It is important to note that these are just a few of the traits that can make it difficult to develop a vaccine against a pathogen. There are many other factors that can contribute to the difficulty of vaccine development, such as the cost of vaccine development, the availability of funding, and the political will to support vaccine development.

A. Constant
B. Average
C. Instantaneous
D. Initial
Answers
Answer: average
Explanation:
If you travel 200 kilometers in 2 hours. Your average speed is 100 kilometers per hour, therefore the correct answer is option B.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.
As given in the problem if you travel 200 kilometers in 2 hours. then we have to find out the term for speed of 100 kilometers per hour,
The average speed of the travel = Total distance traveled / total time
=200 kilometers / 2 hours
=100 kilometers per hour
Thus, if it takes two hours to go 200 kilometers. The right response is B since your average speed is 100 kilometers per hour.
