Why is animal testing bad?
Answer:
Explanation:
Animal experiments may result in clinical trials of biologically faulty or even harmful substances, thereby exposing patients to unnecessary risk and wasting scarce research resources. Animal toxicity studies are poor predictors of toxic effects of drugs in humans.
Answer:
Experimenting with animals is not justified with anything, they practically play with beings that have life, emotions and that feel pain like all living beings.
Advances the experiments that are done on them, are not used, or the purpose is simply lost, as well as their life.

Explanation:
Plants take in carbon dioxide and release gas
Answer:
yes, but by gas you mean oxygen right?
Explanation:
Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

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.

5.. Which compound is formed as a common product of the process of
photosynthesis? *
A.DNA
B.sugar
C.chlorophyll
D.carbon dioxide
Answer:
B.Sugar ( Glucose)
Explanation:
I hope this helps!
A compound that is formed as a common product of the process of photosynthesis is sugar (glucose).
What do you mean by Photosynthesis?Photosynthesis may be defined as a process through which plants utilize carbon dioxide and convert it into glucose in the presence of sunlight.
The reactants of photosynthesis are carbon dioxide and water, while the products are glucose and oxygen.
The reaction of photosynthesis is given below:
[tex]6CO_2 + 12H_2O[/tex] → [tex]C_6H_1_2O_6 + 6O_2 + 6H_2O[/tex]
Therefore, a compound that is formed as a common product of the process of photosynthesis is sugar (glucose).

The animal-like parasite plasmodium causes the disease
Answer:
Malaria is the answer
Explanation:
The animal-like parasite plasmodium causes diseases like malaria.
What is malaria?A parasite that frequently infects a particular species of mosquito that feeds on people can result in a serious and occasionally fatal disease known as malaria.
An obligatory parasite of insects and vertebrates, Plasmodium is a genus of unicellular eukaryotes. The parasite Plasmodium, which causes malaria, is spread via the bite of an infected mosquito.
Malaria often causes severe disease, including high fevers, shivering chills, and flu-like symptoms. Through the bites of female Anopheles mosquitoes carrying the parasites that cause malaria, people can contract this potentially fatal illness. It can be avoided and treated.
Therefore, malaria is brought on by the parasite plasmodium, which resembles an animal.

Explanation:
A long time ago, farmers discovered that if they grow the same
crops on a field, then after a few years, the crops grow more slowly. Why does
this happen?
Answer:
Because they don't have fertilizer.
Explanation:
Well, if this was a long time ago, then farmers did not have fertilizer. So, there are bacteria on the roots of plants that convert nitrogen into a usable form. It's very important for growing, and when farmers harvest the crop, not much of the nitrogen is returned to the land, so it is not as fertile. Fertilizer is largely consisted of nitrogen, so that is why farmers use fertilizers today. But "a long time ago," farmers did not have fertilizer.

A strand of DNA consists of 35% adenine. What is the percentage of guanine in that same molecule
of DNA?
Answer:
Explanation:
We know that the sample is 35% adenine, which tells us that it is also 35% thymine. We know that cytosine and guanine pair together and will be present in equal amounts, so we can divide this final total by 2 to find our answer. The sample is 35% adenine, 35% thymine, 15% guanine, and 15% cytosine.
Answer:
25%
