look at the following images, then in your own words, describe how they are different.
Answer:
they have different locations of where the foods are located
equation of gaseous exchange in plants
Answer:
See the answer below
Explanation:
Gaseous exchange in plants involves the entering of oxygen and the exit of carbon dioxide in its place. It is an important process that helps sustains the life of plants, just like every other living organism. The oxygen that enters is utilized in the process of respiration during which carbohydrates are broken down to unlock their energy for metabolic activities.
Oxygen usually diffuses-in through the stomata while the carbon dioxide diffuses in the opposite direction. The summary of the gaseous exchange is summarized in the equation below:
Glucose (food) + Oxygen ---------> Carbon dioxide + water + energy
Or better still;
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]

(brainliest if right!) How is the dispersive model different from the semiconservative model of DNA replication?
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
2. In the dispersive model, the old double helix is degraded, and in the semiconservative model half of its nucleotides are used in the construction of two new double helices.
3. In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
4. In the dispersive model, one strand of the new double helix is made of DNA, and in the semiconservative model the other strand is made of RNA.
Why do candles extinguish when a lid is closed?
Answer:
fire needs oxygen to burn, when you take that oxygen away by putting a lid on it the fire goes out.
Explanation:
Answer & Explanation:
candles extinguish when a lid is closed because fire needs oxygen to sustain its energy so when the lid is closed no oxygen is coming in, so the candles with the fire slowly extinguish
frank has type A blood (AA or AO) and margarita has type B (BB or BO) blood. They have a new baby. Vinnie, with type O blood. Is this possible or should frank accuse margarita of cheating?
Answer:
It is technically possible, if and only if, both parents have AO and BO blood.
Explanation:
the only way (most of the time) a child can get O blood is if both genes accepted by the parents are O. That would mean both parents would have to have O recessive genes.
What is the main source of Earth's light?
Answer:
The Sun
Explanation:
Answer:
The sun
Explanation:
The main source of light on Earth is the Sun. Sunlight provides the energy that green plants use to create sugars mostly in the form of starches, which release energy into the living things that digest them. This process of photosynthesis provides virtually all the energy used by living things.

TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)
Answer:
False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.
Explanation:
Hope this helps.
It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.
What is nuclear envelope made of?The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.
In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.
The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).
Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.
Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.
Thus, the given statement is true.

(Allele)
Answer:
An allele is a variant of a gene. Everyone has at least 2 alleles for every gene. Because of this, humans are known as diploid organisms.
Explanation:
Genes are the complex proteins that give us hereditary traits such as hair and eye color. But genes mutate, with at least 2 copies per single gene. These copies are known as alleles.

C.the time that it takes you to get to school
D.the route that you take each day
Answer:
The correct answer would be - option C. the time that it takes you to get to the school.
Explanation:
The dependent variable is the factor or variable in any research or experiment is the variable that depends on the independent variable which means it changes with the change in the independent variable.
Here the time the different vehicle takes to get to the school is a dependent variable as it depends on the fact that which vehicle is using and changes with the change in the type of vehicle.

What is the strongest acid listed in 2-2?
What is the weakest acid listed in 2-2?
What is the strongest base listed in 2-2?
Answer:
Strongest acid is hydrochloric acid
Weakest acid is rainwater
Strongest base is sodium hydroxide
Explanation:
pH is defined as the measure of hydrogen ion concentration in a particular solution. pH values seen between 0 and 1 are actually known to be strongest acids. Weakest acids are the ones that move towards neutrality. The neutral pH value is 7.0.
Looking at their pH values, we will discover that hydrochloric acid is the strongest acid. Rainwater is weakest acid because it moves towards neutrality. Sodium hydroxide is the strongest base.
In pH, values between 0-6 are referred to being acidic, 7 is neutral and while 8-14 are basic.

Answer in terms of livor and rigor, what stages and where in the body is it present
Answer:
The common cold and the flu may seem very similar at first. They are indeed both respiratory illnesses and can cause similar symptoms. However, different viruses cause these two conditions, and your symptoms will gradually help you differentiate between the two.
Both a cold and the flu share a few common symptoms. People with either illness often experience:
a runny or stuffy nose
sneezing
body aches
general fatigue.
As a rule, flu symptoms are more severe than cold symptoms. Another distinct difference between the two is how serious they are. Colds rarely cause additional health conditions or problems. The flu, however, can lead to sinus and ear infections, pneumonia, and sepsis. To determine whether your symptoms are from a cold or from the flu, you need to see your doctor. Your doctor will run tests that can help determine what’s behind your symptoms. If your doctor diagnoses a cold, you’ll likely only need to treat your symptoms until the virus has had a chance to run its course. These treatments can include using over-the-counter (OTC) cold medications, staying hydrated, and getting plenty of rest.If you have the flu, you may benefit from taking an OTC flu medicine early in the virus’ cycle. Rest and hydration are also very beneficial for people with the flu. Much like the common cold, the flu just needs time to work its way through your body.
