Answer:
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunligh, so we eat the plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the reen pigment found in the chlorookasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Explanation:
The opposable thumb is a trait that connects us to other primates; allowing us to grab and use tools and increasing chances for survival. This means it is a(n) __________.
Answer:
The options to this question are;
A. genotype
B. adaptation
C. selective pressure
D. stabilizing pressure
The answer is B) Adaptation
Explanation:
Adaptation is the process whereby an organism becomes well suited to survive in its natural environment, which is aided by the possession of certain traits called adaptive features. For example, the fins of a fish makes it fit to survive in an aquatic environment, likewise the opposable thumbs of humans make us well suited to survive in our environment.
As stated in the question, the opposable thumb i.e. movement of the thumb independently of the other four fingers, is a characteristics of primates. This unique feature (opposable thumb) allows us to grab things, get a good grasp of tools, use tools effectively, write things, etc. All these ability due to the possession of opposable thumb increases our chances of survival. Hence, the possession of opposable thumb is regarded as an ADAPTATION

In humans, ventilation, digestion, and blood flow are important biological processes. Explain the relationship between the structure of tissues or organs and one of these processes.
Answer:
I am assuming the question is asking how do the processes relate to one another.
Explanation:
Ventilation happens in the lungs, where carbon dioxide and oxygen are exchanged in the alveoli. This is done via cappilaries that surround the alveoli. Cappilaries are small blood vessels, which are collecitelvy part of the blood flow system (circulation) of the body. In reguards to the digestion, there are capillaries in the vili (which are tiny finger-like structures) so that they can pick up the nutrients during digestion. Another way blood flow and digestion are connected is because the stomach is a muscle, thus is moves and requires energy. That energy comes from the oxygen and nutrients that is supplied by the blood. These are just some examples.
explain the gaseous exchange in lungs
Answer:
Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
Hope it helped u if yes mark me BRAINLIEST!
Tysm!
Answer:
breathing allows the exchange between 2 gases: oxygen and carbon dioxide. Gas exchange occurs in millions of lung alveoli and the capillaries that surround them

Answer:
- Endoplastic reticulum
-cell membrane
-ribosomes
-mithocondrion
^ all the ansers
Explanation:
Cell membrane protects the cell and controls what enters and leaves the cell. So, the correct option is (C).
What is Cell Membrane?
The cell membrane is also called the plasma membrane. It is composed of a semipermeable lipid bilayer that regulates the transport of materials into and out of the cell. It protects the cell and provides a stable environment within the cell, and this membrane serves many functions.
The main function of the cell membrane is to transport nutrients into the cell, while another is to remove toxins from the cell. Cellular membranes are composed of glycerophospholipids, which are molecules composed of glycerol, a phosphate group, and two fatty acid chains.
Thus, Cell membrane protects the cell and controls what enters and leaves the cell. So, the correct option is (C).

What factor about cellular respiration are you testing? ( what makes the three bottles different?)
Answer:
Gas.
Explanation:
Gas which is present makes the three bottles different from one another. There are three factors which is used for testing of cellular respiration such as amount of oxygen consumed during this process, amount of glucose used and amount of carbondioxide produced during cellular respiration. During cellular respiration, oxygen used in order to break down glucose and releases high amount of energy with the waste materials such as carbondioxide gas.

Which of the following statements is true?
Photosynthesis is a type of homeostasis.
Unicellular organisms have differentiated cells.
Respiration is a type of metabolism.
Multicellular organisms are made of only one cell.
Answer:
Respiration is a type of metabolism.
Answer:
C. Respiration is a type of metabolism
Explanation:
Both B and D are incorrect because:
Multicelluar organisms have more than one cell; while singlecelled organisims only have one cell.
Also, homeostasis is a natural way an organisms body reacts to different situations, like when you sweat, your body is realising a way to lower the heat in your body. Therfore, A. is also incorrect.

how does the cell wall contributes towards maintaining homeostasis in the cell
Answer:
The water wants to flow from the higher concentration, which is outside of the cell, to the lower concentration, which is inside of the cell. The cell membrane helps to regulate and slow down the flow of water into the cell. This is yet another way that the cell membrane helps maintain homeostasis.

Ultra-high-temperature sterilization effectively reduces microbes that cause spoilage. removes only mesophilic microbes. reduces microbes that cause disease. removes all microbes that cause diseases or spoilage. reduces microbes that cause disease or spoilage.
Answer:
kills all microbes that cause disease or spoilage.
Explanation:
There are different methods of sterilization, such as ultraviolet radiation, autoclave mechanisms, etc.
The sterilization mechanisms eliminate the microorganisms completely, thus generating sterile surfaces.
These mechanisms are used with surgical instruments, the operating room environment.
The autoclave method is the most widely used today due to its economical price, its ease of use and its practicality.
Sterilization methods must be strictly controlled with pilot or test microbiological cultures to be able to corroborate that these mechanisms function correctly, since otherwise they could trigger strong pathologies due to cross contamination.
