Answer:
He identify DNA as a distinct molecule of the cell.
Explanation:
In the year 1869, Friedrich Miescher separated "nuclein," DNA with associated proteins, from cell nuclei. He was the first scientist who identify DNA and considered as a distinct molecule present in the cell. He is well known for his incorrect tetranucleotide hypothesis of DNA. He formed the first photograph of the structure of DNA and also created the first accurate model of structure of DNA.

Answer:
Golgi complex and Nucleus.
Explanation:
In the diagram, A part is refers to Golgi complex whereas B part is refers to nucleus. Nucleus controls different activities of the cell while on the other hand, Golgi complex produces proteins and lipid molecules that can be used for in other places inside and outside of the cell. The Golgi complex is a cell organelle which is also called Golgi apparatus and Golgi body.

Explanation:
A student wants to perform an experiment to test the effect of different colored lights on the growth of basil plants. She sets up an experiment where multiple basil plants are placed in six different setups; one with red light, one with green light, one with yellow light, one with blue light, one with no light and one with sunlight. In each setup the plant receives the same amount of water, soil, and size of container. What is the independent variable in this experiment
Answer:
light is the independent variable, height of the plant is the dependent variable. Dependent is the effect that based on the independent.
Explanation:
lets break it down. 1) you want to know the effect of something you apply from one thing to another. Let say, if you grow your plants under the sunlight, the plants grow taller. In this case, the sunshine is the independent variable whereas the height of the plant/how tall it can grow is the dependent variable. 2)NOW, before i give the answer. The design of the question is not good for high school students. i think your teacher thinks "light" is the independent variable. 3)However, the question contains confounding variables in it because different lights might produce different effects to the height of the plants. If you want to test if plants are exposed to light grows taller than plants do not expose to light, then you should have all the lights are the same. 4) So, all the plants should be exposed to one certain light to avoid confounding. Confounding means that either red light and sunlight are both produce the same effect whereas the other colors do not help the plants to grow taller. 5)Your teacher should test one light at a time. So, if he is testing with all different colors of light, then light is the independent variable, and height of the plant is the dependent variable.
Climate zones result in specific vegetation types developing in a region. Which
climatic region is hot and wet all year round, resulting in tropical rainforest Vegetation?
Tropical wet and dry climate is typically observed within the tropics. The tropics are two lines of latitude at 23.5° north and 23.5° south of the Equator. Land within this area obtains direct sunlight throughout most of the year.

Explanation:
Think about how diet and weight-loss companies advertise. How do they use bias to sell their products?
Answer:
Companies that advertise diet and weight-loss products are well-known for using false or biased advertising. These companies are biased in the sense that they present images of beauty that are subjective as if they were objectively admirable. Moreover, they can play on people's insecurities due to a bias of what a person should ideally be like. It is very important, when dealing with these type of companies, to use skepticism when examining their data. It is very likely that the data has been modified in order to provide a very positive view of the effectiveness of their products. Moreover, it is important to look at their health claims, and not just at their weight-loss claims.
What are the products of cellular respiration?
A. Energy, carbon dioxide, and water
B. Oxygen, carbon dioxide, and water
C. NADPH and oxygen
D. Glucose and ATP
Answer:
A
Explanation:
Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
So the answer is A. Energy, carbon dioxide, and water
Ella repeated Mendel's second set of experiments. She crossed two non-pure
tall pea plants and produced eight offspring. All of the offspring were tall. She
concluded that her experiment must be flawed.
What is wrong with Ella's reasoning?
A. Ella did not perform enough trials to evaluate the pattern in the
results.
O B. Ella did her experiment correctly. Mendel's experiments must have
been flawed.
C. Ella should have crossed two pure-breeding tall plants.
O
D. Ella did not accurately measure the height of the plants.
Answer:
A
Explanation:
Ella did not preform enough trials to evaluate the pattern in the results.

Which product forms from the reaction between nitrogen (N)
(CI)?
A. NCI
B. NCI
C. N2CI
O D. N2C1
Answer:
None of the above
Explanation:
Because as N has the valence of 3 when it reacts with Cl of 1 as valence they will form NCl3Answer:
The product of the reaction between nitrogen (N) and (CL) is nitrogen trichloride (NCl3)
Explanation:
Although by seeing the question's answer choices, I think it was an error to detect the question (image) by Brainly as 2 of the answers is written the same.
However, when nitrogen gas reacts with chlorine gas, the product is gaseous nitrogen trichloride (NCL3), I guess 1 of your answer must be NCL3.

4. Assertion A: Prokaryotes are identified by the membrane bound cell organelles. Reason R: Prokaryotes are considered as the primitive forms of life. *
a) Both A and R are true and R is the correct explanation of A.
b) Both A and R are true but R is not the correct explanation of A.
c) A is true but R is false.
d) A is false but R is true.
Answer:
d) A is false but R is true.
Explanation:
Prokaryotes are group of organisms that do not possess a membrane bound nucleus or any other membrane bound organelle in their cell e.g. mitochondria, endoplasmic reticulum etc. They lack such organelles.
However, they are truly considered as a primitive life form; much more primitive than eukaryotic organisms. Examples of prokaryotes are bacteria, archeae etc. Based on the above explanation, it is clear that the assertion (A) in this question is FALSE but the reason (R) is TRUE.
Match each root with its meaning.

Scott made a model of the water cycle by filling a tub with water, covering the tub with clear plastic, and placing a heat lamp over the tub. After a few days, he observed water droplets collecting on the plastic wrap. What process formed the water droplets in Scott's model?
Answer:
The correct answer is - condensation.
Explanation:
When humid air comes in contact with the cold surface and we get the water in form of droplets, it is called condensation. In other words, condensation is the change of water vapor to the water exactly opposite of the evaporation process.
In the given experiment of Scott where droplets are collected on the plastic surface which simply illustrates the phenomenon of condensation as the water evaporated due to the heat of the lamp and condensed on the surface of plastic wrap.
Answer:
C
Explanation:
condensation
