What factors contributed to the shift from hunting and gathering to agriculture?
This is a biotechnology question but there isn't a subject choice for it.
Answer:
One of the main factors was a lack of wild animals suitable for hunting and a lack of plants suitable for gathering.
Explanation:
This in turn was due to either climate change or to animal population declines because of unsustainable volumes of hunting and gathering

Explain the importance of decomposers to a food web and their interaction with quaternary consumers.
Answer:
Decomposers recycle the nutrients in dead organisms allowing it to completely travel through the food web cycle, from producer, to consumer and back again
Explanation:
This recycling also applies to quaternary consumers, the predators that generally have no natural enemies, allowing the nutrients in their bodies to be recycled.

how are saturated and unsaturated fatty acids different
Answer:
They are distinct because saturated fatty acids have hydrocarbon chains connected by single bonds solely. Unsaturated fatty acids have one or more double bonds. Each double bond may be in a cis or trans configeration.

The descriptions below explain two ways that water is used by plants on a sunny day.
I. In a process called transpiration, some liquid water in leaves changes to water vapor. The water vapor is released into the air through tiny pores in the leaves. This allows more liquid water from the soil to be pulled up the roots and stem to replace water lost from the leaves.
II. Plants use some of this water in leaves in a process called photosynthesis. During photosynthesis, water and carbon dioxide break apart and recombine to form two new substances, oxygen, and glucose.
Based on the above description of transpiration and photosynthesis, which type of change happens to water during each process?
A. In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change.
B. In transpiration, because some of its properties change, water undergoes a chemical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a physical change.
C. In transpiration, because its physical properties change, water undergoes a physical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a chemical change.
D. In transpiration, because its chemical properties change, water undergoes a chemical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a physical change.

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.

Question 4
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.

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

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.

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.

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.
