The two lower chambers of the human heart are known as:
a.
atriums
c.
auricles
b.
ventricles
d.
blood vessels
Answers
Answer:
b. ventricles
The right and left ventricles
Answer:
B(ventricles)
Explanation:
So lets go over the heart.
First blood circulates from your body to your heart. This is through blood vessels. These blood vessels are connected to the inferior and superior vena cava that go into the heart.
So, this means that the blood vessels are outside of the heart, not the lower areas.
Then, the blood goes into the right artierium, and down to the right venticle. So, thinking about this, it means that the artieriums are the top chambers.
The word auricles is another word for artiums, which we already know are the top chambers.
The venicles are below this, these must be the bottom chambers.
I attached files of some notes I took on the heart, they show the strucutre of the heart and the workings of the heart and circulatory system.
Hope my answer or notes helps! ;)

2. In July, a student tested the soil in two plots and calculated the
concentration of nitrogen compounds present in each plot. The student
then planted 20 seedlings in the first plot and allowed them to grow.
Nothing was planted in the second plot. The student tested the soil in both
plots again after one month. The concentration of nitrogen compounds
had decreased in the first plot but had remained the same in the second
plot. Which of the following best explains the decrease in nitrogen
compounds in the first plot? *
A. The nitrogen compounds had broken down into elements.
B. The nitrogen compounds were absorbed by the seedlings for their growth.
C. The nitrogen compounds escaped through air pockets created by the seedlings'
roots.
D. The nitrogen compounds had evaporated because of the warm summer
temperatures.
Answers
Answer: B. The nitrogen compounds were absorbed by seedlings for their growth.
Explanation:
For the plant to have energy accessible when and where it needs it to maximize yield, nitrogen is essential. As proteins and enzymes control water and nutrient intake, this important nutrient is even present in the roots. Thus, option B is correct.
What nitrogen compounds were absorbed by the seedlings?Plants absorb ammonium and nitrate during the assimilation process, and these substances are then converted into organic molecules containing nitrogen, such as DNA and amino acids.
Plants may absorb substances from soils like nitrate, nitrite, ammonia, and ammonium, which are subsequently utilized to create proteins in both plants and animals.
Therefore, The nitrogen compounds were absorbed by the seedlings for their growth. After they reach three inches in height, seedlings should be fertilized; after that, they can get weekly fertilization until being transplanted.

Describe the steps of transcription
Answers
Answer
The various steps in the transcription and translation process of protein synthesis are described below.
Explanation:
Proteins (made up of amino acids) have an important role in the various functioning process of an organism. Protein synthesis which takes place in the cells of an organism consists of two major processes: transcription (DNA to RNA) and translation (RNA to protein).
Transcription: It is the first process in protein synthesis which occurs in the cell nucleus where a single-stranded messenger RNA (mRNA) is created using a DNA strand and the genetic instructions in DNA are transferred to this mRNA. The steps in transcription are initiation, elongation, and termination. The beginning process known as initiation occurs when an enzyme RNA polymerase binds to a promoter (region of a gene) and the DNA unwinds. One of the DNA strands acts as a template and the enzyme reads the bases in the template DNA strand.
The next step is elongation, where the RNA polymerase builds a strand of mRNA by the addition of nucleotides using complementary base pairs. Here, adenine (A) in the DNA binds to uracil (U) in the RNA. Termination is the last step in which the transcription process ends when the RNA polymerase comes across a termination sequence in the gene. Thus, the completed single-stranded mRNA detaches from DNA.
Translation: It is the second process in protein synthesis which occurs in the ribosome of the cell where the genetic information in mRNA is used to create a protein from amino acids. A triplet of nucleotides is called a codon and they define amino acids. There are 64 possible codons and the codon, AUG acts as the start codon which initiates translation in addition to specifying the amino acid methionine. In the initiation step, the first amino acid in the polypeptide chain is brought by transfer RNAs (tRNAs) to bind to the start codon of mRNA. During elongation, each type of tRNAs in the cytoplasm bound to a specific codon on the mRNA template and adds the corresponding amino acid to the polypeptide chain. Stop codons (UAA, UAG, or UGA) terminate protein synthesis and release the polypeptide.
