How would the equilibrium change if the ocean became more acidic?
Answer: more H2CO3 is made
Explanation:
Acidic water of the ocean creates instability in the ocean ecosystem.
What happens when ocean become acidic?If the acidity of ocean increases the corals can't build skeletons and the shellfish also can't build the shells which they need for protection.
Corals are particularly important because they provide homes for many other sea creatures so we can conclude that acidic water of the ocean creates instability in the ocean ecosystem.

2. How are the atmosphere, hydrosphere, and lithosphere related in the
biosphere?
Answer:
For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere). River action erodes banks (lithosphere) and uproots plants (biosphere) on the riverbanks.

How cells make proteins quick check. Select the statement that is true
Answer:
In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.
In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.
What are proteins?The protein molecules that the genes in DNA encode are the "workhorses" of the cell, performing all the tasks required for life. Proteins include, for instance, DNA polymerases and other enzymes that produce copies of DNA during cell division, as well as enzymes that metabolize nutrients and synthesize new cellular components.
The simplest definition of gene expression is the production of the gene's corresponding protein, and this complex procedure involves two main phases.
Transcription is the process by which the data in DNA is converted into a messenger RNA (mRNA) molecule in the initial phase. A pre-mRNA molecule is formed during transcription by an enzyme called RNA polymerase II using the DNA of a gene as a template for complementary base-pairing.
Therefore, In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.

AMP-PNP is a non-hydrolyzable ATP analog that cannot be metabolized by cells. Taurocholate is a bile acid that helps emulsify fats. When taurocholate is added to hepatocyte cell culture, it accumulates in those cells. The graph below shows the rate of cellular accumulation of the drug taurocholate in the presence of either no ATP, ATP, or AMP-PNP. Based on this data, describe the mechanism by which taurocholate enters the cell. Justify your answer.
Answer:
ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.
Explanation:
ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell.
What is ATP?
A vital "energy molecule" present in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers energy to cells by releasing its phosphate groups when it interacts with enzymes like ATP triphosphatase.
Particular to plants and cyanobacteria is the process of photophosphorylation. During photosynthesis, it is the conversion of ADP to ATP utilizing solar energy. In the mitochondria of a cell, the process of cellular respiration also results in the formation of ATP.
This can be done through either anaerobic or aerobic respiration, depending on whether oxygen is present.
Therefore, ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell.

Carbon dioxide is released as a byproduct of cellular respiration. Which one of these products is also formed during the metabolic reaction of cellular respiration? (B.9B)
Question 16 options:
Water
Glucose
Sucrose
Oxygen
The product that is also formed apart from the carbon dioxide during the cellular respiration process is water. The correct option is A.
What is cellular respiration?Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, which is then used to drive ATP production.
Cellular respiration is the process by which cells in plants and animals convert sugar into energy, which is then used to perform cellular work.
The goal of cellular respiration is straightforward is that it provides cells with the energy they require to function.
Carbon dioxide and water are the byproducts of cellular respiration. Carbon dioxide is exhaled from your lungs after being transported from your mitochondria to your red blood cells. ATP is produced during the process.
Thus, the correct option is A.

Identify and investigate the properties of minerals. Identify and classify a variety of rocks.
based on physical characteristics from their origin, and explain how they are related using the
rock cycle. (i.e. Sedimentary, igneous, and metamorphic rocks)
Answer:
Igneous rocks are classified on the basis of their composition and their texture. Magma, and the igneous rock it becomes, has a range of chemical compositions. For example, basalt is a mafic lava flow rock which originates from melting of the upper mantle.
Explanation:
Answer:
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.

What role does concentration gradient play in movement across a cell membrane
in active transport?
Transport across a cell membrane is a tightly regulated process, because cell function is highly dependent on maintain strict concentrations of various molecules. When a molecule moves down its concentration gradient is it participating in passive transport; moving up the concentration gradient requires energy making it active transport.
During the process of fertilization and pregnancy, which becomes implanted on the uterine wall? (1 point)
gamete
O sperm
Oblastocyst
embryo
Answer:
That is C.) blastocyst. I hope this helps! :)
During pregnancy after fertilization, the embryo gets implanted in the uterine wall. So the correct option is D.
What is an embryo?The embryo is the stage of an animal's early development when it is within an egg or a mother's uterus. When referring to an unborn person, the phrase is used up to the end of the seventh week after conception; starting with the eighth week, the term "fetus" is used.
When an ovum and a sperm unite to form a sexually reproducing organism, the outcome is a zygote, or fertilized egg, which goes through a series of divisions known as cleavages as it travels down the fallopian tube. A hollow ball known as a blastula is created by the cells following many cleavages.
In most animals, the blastula adheres to the uterine lining, causing the placenta to develop and begin supplying the developing fetus with nourishment from the mother. The yolk feeds the embryo in lower animals.
The embryo differentiates into three types of tissue through the process of gastrulation: the ectoderm, which produces the skin and nervous system; the mesoderm, from which connective tissues, the circulatory system, muscles, and bones develop; and the endoderm, which produces the digestive system, lungs, and urinary system.
Therefore the correct option is D.
