Answer:
guanine
Explanation:
The four bases that make up this code are adenine (A), thymine (T), guanine (G) and cytosine (C). Bases pair off together in a double helix structure, these pairs being A and T, and C and G. RNA doesn't contain thymine bases, replacing them with uracil bases (U), which pair to adenine1.
The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)
Can somebody tell me if I’m correct ? I’m timed
how can you maximize the use of useful materials that you have identified
Answer:
By recycling.
Explanation:
By recycling we can maximize the use of useful materials because in recycling process, the material can not be produced again in the laboratory but will be used in after cleaning process which decreases cost of production on the materials and can be sold at high profit. For example, the plastic bottle can be used again after the recycling process so recycling enables us to use the useful materials maximum times.

NEED HELP ASAP!!!!!!!!!!!!!! Place these organisms (I have used the scientific names) in order from the least to most number of cells: Sorex minutus, Homo sapiens, Bacillus anthracis, Sequoia sempervirens. Look up these organisms' names if you don't know what they are.
Answer:
Bacillus anthracis
Sorex minutus
Homo sapiens
Sequoia sempervirens
Explanation:
Cells of different organisms are usually around the same size - so the larger the organism, the more cells.
Bacillus anthracis is a single celled bacteria, so it has the least amount of cells - one.Sorex minutus is a small shrew, so has less cells than a human or giant tree.Homo sapiens are humans - which have more cells than a small shrew.Sequoia sempervirens are huge trees, and likely havethe most cells.Meiosis ensures the transmission of traits from one generation to the next. At the same time, it is a key process that introduces genetic variation into the traits that offspring inherit from their parents.

Sort the following events into two categories:________.
1. Carcinogenic—changes that could cause cancer
2. Anti-carcinogenic—changes that could stop cancer
a) activation of cyclin gene expression
b) activation of a phosphatase that affects kinase 3 of the MAP kinase pathway
c) activation of a phosphatase that affects p53
d) activation of DNA synthesis genes
e) blocking GTPase activity of the G-protein α subunit
f) blocking degradation of p53
g) blocking dimerization of PDGF receptors
h) blocking cyclins from binding to cyclin-dependent kinases
Answers:
a) carcinogenic
b) anti-carcinogenic
c) carcinogenic
d) carcinogenic
e) carcinogenic
f) anti-carcinogenic
g) anti-carcinogenic
h) anti-carcinogenic
Explanation:
Cyclins are proteins that regulate the progression through the cell cycle, i.e., the transition of G1 to S phase. It is well known that high cyclin expression may lead to cell proliferation states, which is closely associated with cancer progression. Moreover, the blockage of cyclins may have an anti-carcinogenic effect by inhibiting the progression through the cell cycle. MAP kinases are serine/threonine kinases that regulate the progression through the cell cycle by phosphorylating a variety of substrates during cell proliferation. In consequence, phosphatases that inactivate MAPK kinases (i.e., by dephosphorylation) may have an anticarcinogenic effect. The p53 is a tumor suppressor protein involved in diverse cellular processes including DNA repair, cycle arrest and programmed cell death. This protein (p53) is activated by phosphorylation at target residues and phosphatases inactivate it, thereby the blockage of its degradation may have an anticarcinogenic effect. Oncogene activation (i.e., the expression of oncogenes), may alter diverse cellular processes including DNA replication, and thereby may lead to cancer development. The G-protein α subunit is a GTPase that hydrolyses GTP and thus has a major role in controlling the kinetics of the G-protein signaling cascade. Platelet-derived growth factor receptors (PDGFR) are kinase receptors that play roles in regulating cellular differentiation, cell proliferation and cell growth. PDGFR receptors are present on the surface of normal cells, however, it has been shown that mutations of the PDGFR genes that lead to their high expression lead to uncontrolled cell growth and consequently cause cancer (i.e., by increasing PDGF signaling).

What is DNA?
DNA is defined as deoxyribonucleic acid and it is a polymer made up of two polynucleotide chains that arranged in helical structure to form a double helix carrying genetic information for the various processes such as growth development functioning and reproduction.There are four nitrogen bases of DNA nucleotides are such as adenine, thymine, guanine and cytosine.
Friedrich miescher discovered DNA in the year of 1860.The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.
In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA. The shape of DNA is double helical structure. Siblings share only about 50% of same DNA due to the reason of recombination. The life span of DNA is 521 years.

How can poor nutrition affect individual cell functions?
Answer:
Nutritional imbalance is a major challenge for living organisms to achieve systemic homeostasis and maintain normal physiology. Mammals have developed processes to control systemic nutrient utilization and storage. For example, excess nutrients are converted and stored in adipose tissue, liver, and muscle during times when nutrients are abundant. By contrast, stored nutrients are metabolized to provide energy and building blocks to maintain vital physiological processes when nutrient availability is low.
From these processes, adipose tissue volume changes in response to under- or overnutrition. This change in adipose tissue volume, in turn, influences the secretion of hormones and cytokines from adipose tissue (adipocytokines). Many of these adipocytokines have important immune signaling functions which can influence immune cell biology and alter the immune response.
which action has the least impact on the environment

Which action has the least impact on the environment?The action has the least impact on the environment is using a safe fountain for clean drinking water. The plants use sunlight, water, and carbon dioxide to make sugars as well as food. Organisms can be divided into autotrophs and heterotrophs according to their pathway of producing food and energy. Heterotrophs are that organism which depend on another organism for their food and energy. They get their energy from carbohydrate, protein, and fat.
Those organisms that are able to make and produce energy from energy-containing organic molecules such as glucose from inorganic raw material such as water and by using light energy such as sunlight are autotrophs. Plants are the prime autotrophs, they produce their food and energy which is sugar from water, sunlight and carbon dioxide using photosynthesis.
Therefore, The action has the least impact on the environment is using a safe fountain for clean drinking water.

How do decomposition and synthesis reactions work
to serve the needs of individual cells of your body?
Answer:
Because those chemical reactions help the cell to dispose useless substance after they are used and synthetize substance they need or the body needs through them.
Explanation:
Hello.
In this case, since the overall processes inside the cell are constantly producing and getting rid of several substances such as nutrients, proteins, lipids and other, we can say that decomposition reactions serve as a mechanism that the cell uses in order to obtain energy or dispose a substance that is no longer important for it. Moreover, since the cell is the fundamental part wherein the most of the useful substances the body needs are synthetized, we can infer that synthesis reactions must occur in order to allow the body to perform lots of functions, for instance, proteins associated to the hair or nails growing are synthetized inside the cell via the protein synthesis mechanism.

Which statement best describes the movement of water into or out of a plant during photosynthesis?
A. It is given off into the soil.
B. It is taken in from the air.
C. It is made in the plant.
D. It is taken in from the soil.
Answer:
D
Explanation:
One reactant of photosynthesis is water, meaning it is needed to start the process. So, it must be taken in. It is more logical for water to be taken in from the soil since we water plants' roots, so it is D.
The statement 'it is taken in from the soil' BEST describes the movement of water into or out of a plant during photosynthesis (Option D).
Photosynthesis refers to a series of metabolic reactions by which plant cells use the light energy from the sun, carbon dioxide and water to produce simple sugars (e.g., glucose) and oxygen.In consequence, during photosynthesis, water is a reactant taken from the soil.The photosynthetic reactions involve the oxidation of water (these molecules lose electrons) and the reduction of carbon dioxide (these molecules gain electrons).In conclusion, the statement 'it is taken in from the soil' BEST describes the movement of water into or out of a plant during photosynthesis (Option D).
