Answer:
Hibiscus plant: transported by the phloem
Paramecium: simple diffusion from the food vacuole into the cytoplasm
Coral polyp: diffusion from the gut to the body cells
Earthworm: transport through the blood
Mosquito: transport through the blood
Humans: transport through the blood
Explanation:
Digestion involves both mechanical and chemical processes to break up
food into smaller or simpler constituent parts that can be absorbed by the body.
Digestion is divided into external digestion and internal digestion.
External digestion involves digestion of food outside the body using digestion enzymes and then absorption into the body by diffusion.
Internal digestion is when food is ingested into the body, broken down by Digestive enzymes and juices and then absorbed into the body cells.
A hibiscus plant stores it's food as starch. When the stored food is needed, it hydrolyses starch into molecules small enough to pass through the cell membrane. The hydrolysed food molecules are then transported by the phloem to cells that need them for energy production.
A paramecium is a protist which feeds by endocytosis, i.e. sorrounding and digesting food in its food vacuole. The digested food diffuses through the cell
cytoplasm and mitochondria oxidise it to produce ATP.
A coral polyp is a marine invertebrate belonging to the phylum Cnidaria.
Cnidarians have a simple sac-like gut, with only one opening and one unspecialised gut chamber.
They do not have a circulatory system to deliver nutrients to the cells, instead digested food diffuses from the gut to the body cells.
An earthworm is an annelid and carries out internal digestion. Food taken in from the mouth is digested and absorbed by the intestines into the blood. The blood then carries the absorbed food to the earthworm’s body cells.
Mosquitoes both male and female feed on sap and nectar, aphid honeydew, and plant juices, but in many species the mouthparts of the females are adapted for feeding on the blood of other organisms.
Food taken in by the mosquito is digested in the mid-gut by digestive enzymes. The blood absorbs digested food from the mid- gut and carries it to its body cells.
In Humans, digested food molecules are absorbed in the small intestine into our bloodstream. The blood then carried digested food molecules around the body to the cells where they are needed.
Identify and describe the three ways that mutation affect organisms
Answer:
they may cause the development of a disease-causing allele
they may cause the development of a more beneficial allele
they in some cases, may have no noticeable affect
Explanation:
Answer:
Sample Response: Mutations may be beneficial, harmful, or neutral to organisms. If the change caused by a mutation is useful to the organism, then it is beneficial. If the change is damaging to an organism, then it is harmful. If the change is neither useful nor damaging, then the mutation is neutral.

Explain photosynthesis in a paragraph.
Answer:
Photosynthesis is the synthesis of glucose from carbon dioxide and water in the presence of sunlight and chlorophyll with oxygen as a by-product it occurs in green plants,photosynthetic bacteria and some algae it is an anabolic(building) process and nearly all life depends on it it comprises many coordinated biochemical reactions that are necessary for the survival of the species it is divided into two phases 1 light reaction(Z-scheme) 2 dark reactions(Calvin cycle)
Explanation:
I hope this will help you:)
Answer:
Photosynthesis is the process through which autotrophs are bale to produce their own food. The Process is named so because photo means sun's light and synthesis means creating. It involves the Plants or other autotrophs absorbing the sun's light and also carbon dioxide released into the atmosphere by respiration. As a result of Photosynthesis, we obtain what is known as oxygen. This is, in fact, the biproduct of the process. Mainly, Photosynthesis occurs due to the presence of Chlorophyll which give leaves their green colour.
Key:
Autotrophs: Those who have the ability to produce their own food.
Biproduct: The extra result of a scientific equation.
Chlorophyll: a green pigment, present in all green plants and in cyanobacteria, etc.

Your classmate describes a growing baby as “a ball of multiplying cells that eventually grows large enough to form a baby.” Explain why this statement isn’t completely accurate.
Answer:
Please, see the answer below.
Explanation:
The statement is inaccurate because a growing baby is not just a ball of multiplying cells that eventually grows large enough to form a baby.
After fertilization and the formation of a single-cell zygote, the zygote continues to divide to form a ball of cells. However, at some points, the cells start to differentiate to give rise to various organs that make up the baby.
Without differentiation, there is not way the dividing cells will give rise to baby. Hence, a growing baby should be rather viewed as a ball of multiplying cells that eventually differentiates to form a baby.
Answer: Embryos start as a ball-like structure of rapidly dividing cells. However, at a certain point in development, these cells diversify and bind together to form larger structures, such as tissues, organs, and, eventually, full systems.

The block is moved leftwards and the spring's right end is displaced from the position of 0.250\,\text m0.250m0, point, 250, start text, m, end text to 0.150\,\text m0.150m0, point, 150, start text, m, end text where it is held in place. All positions are measured from the origin OOO of the wall.
Answer:
The force of spring will be "3.75 N". The further explanation is given below.
Explanation:
The given values are:
Spring constant, K = 75.0 N/m
x₁ = 0.200 m
x₂ = 0.150 m
So that,
⇒ [tex]x=x_{1}-x_{2}[/tex]
⇒ [tex]=0.200-0.15[/tex]
⇒ [tex]=0.05 \ m[/tex]
Now,
Force of spring will be:
⇒ [tex]F=K\times x[/tex]
On putting the estimated values, we get
⇒ [tex]=75\times 0.05[/tex]
⇒ [tex]=3.75 \ N[/tex]
Answer:
−8.25N
Explanation:
Hooke’s law says the restorative spring force is directly proportional to the change of the spring length x on top, but is opposite in direction to the change in spring length.

When is the lac operon most active?
A. When glucose levels are high and lactose is present
B. When glucose levels are low and lactose is absent
C. When glucose levels are low and lactose is present
D. When glucose levels are high and lactose is absent
Answer: The correct answer to the question is option WHEN GLUCOSE LEVELS ARE LOW AND LACTOSE IS PRESENT.
Explanation: To start with,Lac operon can be simply defined as a part of the DNA that is under the part of the DNA is manipulated and controlled by the same promoter,they can be found in some prokaryotic cells giving room for regulation over excess synthesis of protein.so simply put,these specific segment of the DNA binds with the segment of the polymerase of RNA so that transcription of the mRNA from the operon genes will be achieved.
Lac operon is also known as lactose operon, it is seen in some enteric bacteria like e.coli where they play a crucial role in coding of genes for those proteins that function in moving lactose into the cystocel and digesting it to form glucose that is used for energy generation. These lac operon are are most active when glucose levels are low and lactose is present,with the low level of glucose, the lac operon can be transcribed to a high level,this is to ascertain that the bacteria only gets to activate the lac operon and can only make use of it,that is using lactose when all the preferred energy source from glucose has been exhausted.

Computer simulation is becoming a commonly used process to efficiently model and evaluate the impact of a variety of proposed solutions when facing a complex real-world problem. Reasons for using computer simulation over actual production of possible solutions include all except:
A) costs associated with testing and prototyping too high
B) computers are not as trustworthy as actual prototypes are
C) trial system would not withstand significant testing desired
D) time necessary to acquire and analyze results prohibitively long
Answer:
The correct answer is option B) "computers are not as trustworthy as actual prototypes are"
Explanation:
It is false to affirm that results obtained from computer simulations towards looking for solutions of real-world problems are not as trustworthy as results obtained from actual prototypes. In most cases, computer simulations had proved to be reliable, particularly when the programers use validating arithmetic and algorithms. There are multiple companies dedicated to develop computer simulations to solve real-world problems, which are constantly used and tested in scientific investigations.

emphysema and asthma are respiratory disorders that may both be attributed to smoking; they also share many symptoms in common. As a physician, how would you distinguish between these two disorders when diagnosing a patient? explain.
Emphysema happens when the tiny sacs in your lungs (called alveoli) are damaged. Chronic bronchitis is when the tubes that carry air to your lungs (bronchial tubes) get inflamed. Smoking is the most common cause of those conditions (and COPD).
Some people have asthma and COPD at the same time. If you have symptoms of both diseases, your doctor may call it asthma-COPD overlap syndrome.
People who smoke or breathe in pollution or chemicals at work for many years have higher chances of having COPD. That's why the condition often starts in middle age or later in life.
Asthma is sometimes caused by gene changes that are passed down through families. If one of your parents has the disease, you're more likely to have it. Symptoms often start in childhood.
Since asthma and COPD both make your airways swell, they both can cause shortness of breath,coughing, and wheezing.
One main difference is that asthma typically causes attacks of wheezing and tightness in your chest. COPD symptoms are usually more constant and can include a nasty cough.
To figure out which condition you have, your doctor will start with a physical exam and questions about your medical history. They’ll look at your nose and throat and listen to your lungs with a stethoscope. Your doctor will also want to do a test called Spirometry that checks how well your lungs work.

Which venn diagram accurately describes what characteristics of solids, liquids, and gasses could be added to this diagram
Answer:
See explanation for image
Explanation:
The Venn diagram that can accurately show the characteristics of solids, liquids, and gases, can show which characteristics are unique to each of these states of matter and which characteristics are shared among the three.
You did not present the answer options, but it was possible to find them in questions like yours. These answer options are in the figure attached below and among them, the letter B is the correct answer.
Regarding the Venn diagram, we can say that:
The diagram consists of three circles, which overlap, sharing a small space, in the center of the three.Each circle represents a different element.The part of the circle that is away from the shared center refers to the particular characteristics of each element.The part of the circle that is within the shared center refers to the characteristics shared between these elements.In diagram B shown in the figure below, it meets all the requirements shown above.
In this diagram, the shared center presents the common characteristics of solids, liquids, and gases. However, the top circle shows the particular characteristics of solids. The circle on the left shows the particular characteristics of gases, while the circle on the right shows the particular characteristics of liquids.
