Answer:
The double helix
Explanation:
A student made a model of an onion skin cell she viewed
using a microscope. The scale is 500:1. The student's cell
model has a length of 15 cm.
How many centimeters is the real cell's length?
A. 7500 cm
B. 0.002 cm
C. 33 cm
D. 0.03 cm
If a student made a model of an onion skin cell using a microscopic magnification scale of 500:1 and the length of the modeled cell is 15 cm, the real cell's length would be 0.03 cm.
The scale is 500:1. This means that the dimension of the real cell without being magnified under the microscope would be 1/500.
Thus, if the length of the cell under the microscope is 15 cm. This length has been multiplied by 500. In order to get the real length, it must be divided by 500.
15 x 1/500
= 0.03 cm

Describe the activities of DNA and the three types of RNA.
Answer:
There are three types of RNA: mRNA, tRNA, and rRNA. mRNA is the intermediary between the nucleus, where the DNA lives, and the cytoplasm, where proteins are made. rRNA and tRNA are involved in protein synthesis. Additional RNAs are involved in gene regulation and mRNA degradation.

Answer:
is to go for medical check-up
Explanation:

you will know that it still crenated
The only way to tell if the red blood cells are crenated is to observe them under a microscope
What is crenation?Crenation is the process of red blood cells becoming misshapen and breaking apart, and this can be seen through the examination of red blood cells under a microscope.
By observing the shape of the red blood cells, it can be determined if they are crenated or not. Additionally, other methods such as hemoglobin analysis or measuring the osmotic fragility of the red blood cells can also be used to determine if crenation has occurred.

Newly synthesized proteins destined to be secreted from the cell are likely to be found in all of the following places EXCEPT:
The lumen of the ER
The lumen of the Golgi
The lumen of the lysosome
The lumen of the SER
Moving to the next question prevents changes to this answer.
Newly synthesized proteins destined to be secreted from the cell are likely to be found in all the options except the lysosome.
Both the endoplasmic reticulum and Golgi apparatus are involved in protein processing and transport.
However, the lysosome is an organelle responsible for digesting or degrading excreted biomolecules as well as dead organelles. The lysosome is spherical and most contain digestive enzymes capable of degrading biomolecules in its lumen. Thus, a protein destined to be secreted from the cell will most likely not be found in the lysosome, otherwise, the protease enzyme present in its lumen would degrade them.

which molecule gets translated into a protein by the ribosome?
Answer:
Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
Explanation:
Molecule gets translated into a protein by the ribosome within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
What is RNA?Full form of RNA has ribonucleic acid and it has a nucleic acid which has been found in almost all cells that are living and RNA has mostly similar to DNA but there is one difference between RNA and DNA and the difference is that RNA has single stranded but DNA is double stranded.
The RNA has backbone has made up of the phosphate group which has arranged in alternating form and the sugar known as ribose other than the deoxyribose present in DNA. There are four bases found in RNA and these are adenine, uracil, guanine, and cytosine.
The main function of mRNA is it work as imedieter between protein and DNA which is utilised by ribosome for the process of direct synthesis of protein, and the function of tRNA is to carry the accurate amino acid to the proteins synthesis site which takes place in ribosome.
Therefore, Molecule gets translated into a protein by the ribosome within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis the stitching together of amino acids to make a protein molecule.

the two proteins directly involved in muscle contraction are broadly called
The two proteins directly involved in muscle contraction are MYOSIN AND ACTIN. The interaction between these proteins is responsible for muscle contraction.
The sarcomere is the basic unit of muscle cells (myofibrils) that mediate muscle contraction both in skeletal and cardiac muscle tissue.
During muscle contraction, myosin and actin proteins slide past each other, thereby leading to sarcomere shortening.
The myosin protein binds to actin filaments and thus myosin acts as a motor protein that drives filament sliding.

Explain in your own words the difference between a leading strand and a lagging strand.
Answer:
So basically the primary distinction between the leading and lagging strands is that the leading strand is the DNA strand that develops continuously during DNA replication, whereas the lagging strand is the DNA strand that grows in small pieces known as Okazaki fragments. A leading strand is one that is produced in the 5'-3' direction, whereas a lagging strand is one that is formed in the 3'-5' direction. The leading strand is constantly produced where the other is not.

What is a snake that eats a mouse an example of?
predation
competition
mutualism
parasitism
Answer:
Predation
Explanation:
A snake that eats a mouse an example of predation.
A snake that eats a mouse is an example of predation. Predation is an ecological interaction where one organism (the predator) kills and eats another organism (the prey). Hence option A is correct.
What is predation?Predation is an ecological interaction between two organisms in which one organism (the predator) hunts, kills, and eats another organism (the prey). It is a form of consumption where the predator obtains nutrients and energy from the prey, while the prey is typically harmed or killed in the process.
In this case, the snake is the predator and the mouse is the prey. Predation is a natural and common interaction in many ecosystems, and it can have significant effects on population dynamics and community structure.
It can help regulate prey populations, prevent overgrazing, and promote species diversity.
Predators have evolved various adaptations to catch and kill their prey, while prey has evolved various defenses to avoid being eaten, such as camouflage, warning coloration, and physical or behavioral defenses.
Hence option A Predation is correct.
