The process by which plants make their own food is called photosynthesis. The raw materials of it are carbon dioxide coming from stomata, water and sunlight.
What is stomata?Stomata is the opening for gaseous exchange and transpiration, present in epidermis of leaf.
Stomata are provided by two guard cells, which shrink and swell in order to open or close the stomatal pore respectively.
The carbon dioxide necessary for photosynthesis enter plants through these openings called stomata.
Thus, option b is correct.

What are the two divsions of the peripheral nervous system?
Answer:
The answer will be somatic nervous system and autonomic nervous system.
Explanation:
Nervous system contain many interconnecting nerves that helps brain to respond according to stimuli. The nervous system is divided into central and peripheral nervous system. Peripheral nervous system again divided into the somatic nervous system and the autonomic nervous system.
What is nervous system?The peripheral nervous system consists of nerves that comes out from brain and spinal cord.
These nerves helps to form a network for communication between central nervous system.
Peripheral nervous system is divided into:
Autonomic nervous system: It is visceral efferent system as it sends motor impulse to visceral organs.Somatic nervous system: It contain sensory and motor neurons that sends and receive sensory information from motor neurons.Thus, there are two divisions of peripheral nervous system, these are autonomic and somatic nervous system.

Which drug class is used to slow the movement of gi contents, causing a decreased ability for muscles to contract?.
Answer:
Anticholinergic drugs are common ingredients in antidiarrheal medications because they significantly decrease intestinal motility and secretions.
Anticholinergics drug class is used to slow the movement of gi contents, causing a decreased ability for muscles to contract.
What are anticholinergics?Anticholinergics are a type of medication which blocks the action of a neurotransmitter known acetylcholine. Acetylcholine transfers signals between cells that affect specific bodily functions. As anticholinergics can affect a variety of functions, including digestion, urination, salivation, they can help treat many conditions.
The medication blocks acetylcholine from causing involuntary muscle movements in the gastrointestinal tract, lungs, urinary tract, and other areas of the body.

In these analyses, why are segments of chromosomes (haplotypes) rather than individual strs used to identify genetic relationships?
The type of analysis is not specified here, but haplotypes are used to identify phylogenetic and phylogeographic relationships.
Whta are haplotypes?The haplotypes are linear sequences of nucleotides whose order can be used to determine evolutionary relationships.
The haplotypes are very useful in phylogeny and phylogeography to study the features of species.
The term haplotype is broader than genetic sequence because a haplotype is more informative (a priori).

Both shall workout for the same time.Measure their heart rate and see who's heart rate is higher.Independent Variable:
AgeExplanation:
Age is different for everyone and independent.Make them workout for the similar amount of time then measure their heart rate.Older person will have greater heart rate.=================================================================
The person with less heartbeat means he has a great fitness.The person with greater heartbeat means he has a bad fitness.The diffusion of water molecules across a semipermeable
membrane and down a concentration gradient is known as
Answer:
Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of lower concentration solution (i.e., higher concentration of water) to an area of higher concentration solution (i.e., lower concentration of water). Water moves into and out of cells by osmosis.
When neither of two alleles is dominant, the resulting trait reflects the influence of both. This is called
dominant inheritance.
codominance.
polygenic inheritance.
This is called codominance
Question: As a result (because) of diffusion, the concentration of many types of substances:
A: always remains greater inside a membrane.
B: eventually becomes balanced/equilibrium on both sides of a membrane.
C: always remains greater on the outside of a membrane.
|| ▼ Answer ▼ ||
B: eventually becomes balanced/equilibrium on both sides of a membrane.
|| ✪ Explanation ✪ ||
Diffusion is the movement of molecules from a high to a low concentration. The effect of diffusion on different substances' concentrations is balance/ equilibrium on both sides of a membrane. In the process of the movement of molecules, the concentration becomes balanced. A typical example of diffusion is a perfume sprayed inside a room. The smell of the perfume will eventually be balanced in the entire room.

How do you think a human egg is similar to a chicken egg? How are they different ?
Answer:
They both eventually lead to the birth of a chicken or human. And they start very similarly. They are very different, also, because instead of having a physical egg, humans have oval eggs that eventually make the baby, before birth. Chickens on the other hand give birth to the chick that is still inside the egg.

Why does the moon have craters in it?
Answer:
Because the Earth has an atmosphere, the Moon has more craters than the Earth. While we sweep up a lot more things because of our higher gravity, the majority of it burns up on entrance and never reaches the earth. Earth also possesses liquid water. This is significant in two ways: first, most things that strike water do not create a crater, and second, water erodes previous craters.

A student wants to learn how plants and animals interact with one another in an ocean habitat. Which of Earth's spheres should the student study the most? the geosphere the atmosphere the hydrosphere the biosphere.
A student wants to learn how plants and animals interact with one another in an ocean habitat thus he should learn about the biosphere as it helps in the determination of living organisms.
Organisms want water, and they take it in from assets including lakes, rivers, the sea, and aquifers. A deer that sips water from a circulate recycles that water with the aid of using exhaling and excreting waste. A fish takes in water from the sea and excretes water again out.
What plants and animals live in the ocean?Seaweeds, algae, snails, crabs, small fishes, mollusks, worms, clams, and crustaceans stay withinside the coastal area. The pelagic area includes an open ocean further from the land and includes floor seaweeds, fish, whales, and dolphins.

Which of the following do you think will contain DNA? Explain your reasoning. bananas __ concrete __ fossils __ meat __ metal __ spinach __ strawberries __
Answer:
fossils, meat, spinach, strawberries
Explanation:
They all were reproduced so they have cells.
Answer:
-bananas
-fossils
-meat
-spinach
-strawberries
Explanation:
These are (or were once) living things, and so they will have DNA. Most living things have DNA, it is like a code on how they were made. The DNA tells us what specific characteristics an animal, plant or other living thing has/had.
For the fossils, the living thing that the fossil depicts wasted away and the fossil was left behind. The fossil had touched the living thing, therefore it had to have left at least a trace of DNA from the original organism.
