Explanation:
Hey, there!!
The teacher is surely describing about kingdom Plantae. Plants and animals posses some similar characteristics such as eukaryotic, multicellular, in the above descriptions. BUT;
The reason for above answer is,
Plants only produce food by themselves in presence of sunlight and chlorophyll. So, they are termed as autotrophic in nature.Similarly, plants cell only posses cellwall made up of cellulose.Hope it helps....
Allison and Heather are going to conduct an experiment to see whether salt affects the growth of plants. They gather five groups of identical plants and give the plants in each group water with a different salt concentration. What is the outcome variable (dependent variable) for their experiment?
Answer:
The dependant variable is the growth of the plants.
Explanation:
The independent variable is what changes the dependent variable.
for example, the type of salt concentration ( Independent variable ) is/ isn't going to change the growth ( dependant variable ) of the plant.
The dependant variable is the growth of the plants.This is the outcome of the experiment in which salt affects the growth of plants.
What are plants?Plants are the eukaryotes means they are multicellular organisms and they belong to the kingdom Plantae. So, the scientific name of plants are Plantae and its domain is Eukaryota.
The plants are of many types such as shrubs, herbs, mosses, ferns, trees and they grow on a particular place by absorbing inorganic substances and water from the soil through the roots.
Plant are also known as autotrophs as they prepares there own food in the presence of sunlight. Due to chlorophyll present in them the plants shows green colour.
Plants are also known as producers because they produce food to feed others.
Therefore, the dependant variable is the growth of the plants.This is the outcome of the experiment in which salt affects the growth of plants.

In C3 plants the conservation of water promotes _____. In C3 plants the conservation of water promotes _____. photorespiration a shift to C4 photosynthesis photosynthesis the opening of stomata the light reactions
Answer:
The correct answer is "photorespiration".
Explanation:
Photorespiration is a process in plants, where molecular oxygen is taken in a light-dependent manner. Photorespiration is often considered a wasteful pathway because it competes with the Calvin cycle, which is much more efficient. In C3 plants the conservation of water promotes photorespiration. This occurs when the C3 plants close its stomata because the environment its too hot, or the carbon dioxide concentration drops to about 50 ppm.
Glucose molecules from food sources provide energy to the cells of the human body. After a person eats, the level of glucose in their blood increases. If a person's blood glucose level becomes too high, a hormone in the pancreas, known as insulin, is released. Insulin helps move glucose out of the bloodstream. This causes the blood glucose level to decrease and return to equilibrium. The production of insulin is a mechanism that regulates the human body's internal environment and aids in
Answer:
regulating blood sugar levels
Explanation:
The primary function of the insulin hormone is to convert the excess glucose in the blood after a meal and store it for later. Glucose gets converted to glycogen, which is a compact molecule ideal for storage. When the body is need of energy, this glycogen is broken down to make up for the lack of glucose present in the blood.

Answer:
Option "C" Oxygen is the correct answer to the following question:
Explanation:
We know that, Just as a human absorbs oxygen into the body through inhalation, the oxygen enters into the whole body also in the blood and is used in the body by cells, so we can say that the human body needs a constant supply of oxygen. therefore, the appropriate option is true

What is the function of epithelial tissue in our body?
Answer:
Functions of epithelial tissue:
i. Epithelial tissue covers the body outside and lines the various cavities inside.ii. Epithelial tissue lines the hollow organs, body cavities, blood vessels and ducts.iii. Cells are rested on thin, doubled layered, non-cellular basement membrane.iv. Epithelial tissue has nerve supply of its own.v. Epithelial tissue is avascular (a = without, vascular = vessel), i.e. it lacks its own blood supply and hence, obtains nutrients which diffuse out of blood vessels.vi. Epithelial tissue has the power of division and regeneration. The old injured dead cells are sloughed off regularly and are replaced by new ones.A student gathered two boxes of the same size made of different materials: glass and clear plastic.

What is the endosymbiotic hypothesis?
Answer: What does the endosymbiont hypothesis propose? It proposes that early eukaryotic cells acquired the precursors of mitochondria and chloroplasts by engulfing certain types of bacteria. ... Mitochondria, chloroplasts, and centrioles in eukaryotic cells each contain their own minute and unique supply of DNA.
Explanation:
The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.

All plants and some algae have a complicated life cycle that includes both a multicellular diploid _______ stage and a multicellular haploid _______ stage. This type of life cycle is called _______.
Answer: sporophyte, gametophyte, alternation of generation
Explanation:
Alternation of generation is a kind of life cycle seen in plants and algae in which the diploid asexual and haploid sexual stages exist. A sporophyte is multicellular and diploid which is an asexual stage. It produces the haploid spores through meiosis. The haploid spores germinate to produce haploid gametophyte. The gametophyte produces gametes by the process of mitosis.

Compare the inputs and outputs of humans and robots in terms of matter and energy.
Answer:A robot is a machine. It is often, or almost always, automatic, which means that it is able to perform activities on its own without the aid of external variables, like humans. It moves in the way that it was originally programmed, or designed to act. These actions are described as ‘intents’ of its own. For example, a robot that is designed to play ping pong will really move like a ping pong player, compared to a robot that is just used for plain surgical operations.
‘Robot’ is also a word that refers to the sum of all the groups of robots, comprised of the physical robots and the virtual robots (as in software). In the case of the latter, these are called bots.
Human beings are also highly social individuals. They survive alongside other people in groups called communities or families. They are capable of forming relationships, and generating complex feelings, or emotions such as love.
1. Humans are organic beings, while robots are not.
2. Humans are far more complex and superior to robots in almost all aspects.
3. Humans are highly social beings compared to robots

3. Lawrence, Kansas and Nashville, Tennessee occupy similar latitudes. Why is one found in a grassland and the other in a forest biome
Answer:
The distance between Lawrence, Kansas and Nashville, Tennessee is 501.74 miles. So they are really far apart.
The location of Lawrance, Kansas is:
Latitude: 38.9560 Longitude: -95.2520.
And for Nashville, Tennessee is:
Latitude: 36.174465, Longitude: -86.767960.
So while the Latitudes are similar, the longitudes are not, and this is why you can see that the geography of each place is different.
