Glycine (C2H5NO2) is added to a growing peptide chain containing methionine (C5H11NO2S) and alanine (C3H7NO2). Which of the following peptide chain orientations best displays the growing chain and peptide bond between the amino acids?
Multiple amino acids are linked together by peptide bond.
It is a kind of bond which is formed by a biochemical process that extracts a water molecule which joins the amino group of one amino acid and carboxylic group of other amino acid.
Amino acids carried by tRNA are covalently attached to the nucleotide.

Which part of plant intake oxygen and give out carbon dioxide?
Any green living plant absorbs carbon dioxide, extracts the carbon and releases the oxygen. The process is called photosynthesis, and is powered by sunlight. The carbon is combined with water and other trace chemicals to form complex organic substances such as starch, wood, etc. On the surface of the leaves of the plants there are a large number of tiny pores known as stomata or stoma. For photosynthesis green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. Each stomatal pore is surrounded by a pair of guard cells. However, plants only perform photosynthesis in the green parts, like leaves and stems, but all plant cells need oxygen to respire. Cells in the leaves get plenty of oxygen from photosynthesis, but cells in the roots often need to get oxygen from the environment to stay alive.
if cells come from pre existing cells what happens to the cell from which it comes? will the cell be of the same size as others or will it be small?
Answer:
All cells require at least some of the molecular machines that you see in the video above, Engineering is one field where information about how physics and chemistry are used to create machines that use coded information to control their functions, Biology is the other. There are no other known systems that use coded information to do anything at all. And of course our genetic code causes the construction of programmable metabolic pathways that allow cells to adapt to their environment in real time, and epigenetics pathways that allow long term adaption. We don't compare biology to human engineered technology out of laziness but because it's the only known comparable phenomenon.

Which of the following is NOT a
statistical test?
A. t-test
B. ANOVA
C. chi-square
D. area
I’m having a hard time in biology:/
Area is not a statistical test. The correct option is D.
What are statistical tests?Statistical tests are mathematical tests performed on data collected from research to make the interpretation of the research easily discernable.
There are two types of statistical tests:
Descriptive statistical testsInferential statistical testsDescriptive statistical tests only arrange data in tables, lines, graphs, etc. It does so that trends can be seen just at a glance.
Inferential statistical tests are performed in order to arrive at logical conclusions based on the data obtained during research. They include t-tests, analysis of variance tests, tests for significant differences, and so on.
In other words, area is not part of any statistical test.

Explain how observation, interpretation, and explanation are important to the study of science.
Answer:
Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing.

Identify what is happening to the carbon in the following example: A cow is eating grass.
A. Carbon is being stored through feeding.
B. Carbon is being stored through decay.
C. Carbon is being released through decay.
D. Carbon is being released through feeding.
Answer: b
Explanation:
When a cow is eating grass, the carbon is stored through feeding. Thus, the correct option is A.
How does carbon get stored in the living body?Carbon gets stored in the body through food intake. This follows the principle of biogeochemical cycles that allows the movement of nutrients throughout the environment.
A cow eating grass represents a feeding process through which the cow gets energy for metabolic as well as physical activities.
Therefore, the correct option for this question is A.

Explain how scientists can have multiple theories about the effects of global warming.
Explanation:
global warming?
Since the Industrial Revolution, the global annual temperature has increased in total by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit. Between 1880—the year that accurate recordkeeping began—and 1980, it rose on average by 0.07 degrees Celsius (0.13 degrees Fahrenheit) every 10 years. Since 1981, however, the rate of increase has more than doubled: For the last 40 years, we’ve seen the global annual temperature rise by 0.18 degrees Celsius, or 0.32 degrees Fahrenheit, per decade.
The result? A planet that has never been hotter. Nine of the 10 warmest years since 1880 have occurred since 2005—and the 5 warmest years on record have all occurred since 2015. Climate change deniers have argued that there has been a “pause” or a “slowdown” in rising global temperatures, but numerous studies, including a 2018 paper published in the journal Environmental Research Letters, have disproved this claim. The impacts of global warming are already harming people around the world.
Now climate scientists have concluded that we must limit global warming to 1.5 degrees Celsius by 2040 if we are to avoid a future in which everyday life around the world is marked by its worst, most devastating effects: the extreme droughts, wildfires, floods, tropical storms, and other disasters that we refer to collectively as climate change. These effects are felt by all people in one way or another but are experienced most acutely by the underprivileged, the economically marginalized, and people of color, for whom climate change is often a key driver of poverty, displacement, hunger, and social unrest

A DNA sequence reads: ACAGTCGATGCA. Which of the following is the correct complementary DNA strand?
CACTGATCGTAC
GTGACTAGCATG
TGTCAGCTACGT
UGUCAGCUACGU
Answer:
its C) TGTCAGCTACGT
Answer:
C. TGTCAGCTACGT
Explanation:
In Chargaff's Rule (or the Complementary base pairing rule):
~ Adenine (A) pairs with Thymine (T)
~ Cytosine (C) pairs with Guanine (G)
Because of this rule, with one strand of DNA already having the sequence of ACAGTCGATGCA, The other strand of DNA can only be a sequence that pairs the nitrogenous bases with their assigned pair/base.
Thus, the answer being TGTCAGCTACGT

What are the reactants in the dark reactions ?
Answer: The reactants in a dark reaction are carbon dioxide (CO2) and water (H2O).
Explanation:
Dark reactions are a type of photosynthetic reaction.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Dark reactions occur in the grana of chlorophyll and get energy from ATP and NADPH.
The reactants are carbon dioxide (CO2) and water (H2O).
What factor affects the root style?
