that was here 100 million years ago? (1 point)
A) Water enters and leaves Earth duing evaporation and precipitation cycles.
B) The water present on Earth today is made of the same atoms but the molecules
have been recycled through biologic activity.
C)The atoms that made the water then were destroyed when they were used; the
atoms that make up water now were made more recently.
D)The molecules of water then are the same molecules that exist today.
Answer:
A. Water enters and leaves Earth during evaporation and precipitation cycles.
Explanation:
Answer:
B
Explanation:
C is wrong because, atoms cannot be destroyed or made according to the law of conservation of mass. D is wrong because water goes through many processes, like A states, but both are wrong because B is the most correct.

The thin, protective mucous membrane composed of nonkeratinized stratified squamous epithelium with numerous goblet cells that is supported by areolar connective tissue is known
The conjunctiva is a thin transparent mucous epithelial membrane that lines the inner surface of the eyelids made up of goblet cells whose function is to protect the eyeball.
The conjunctiva is an almost transparent membrane that covers the white part of the eye, the sclera, and also the eyelids on the inside.
Its function is to protect the eyeball from external agents, although it also intervenes in the formation of tear components and in the immune defense of the eye.The conjunctival epithelium is a non-keratinized squamous stratified epithelium like the corneal epithelium but contains mucin-secreting goblet cells that maintain the tear layer.Therefore, we can conclude that the conjunctiva is a mucous membrane that is formed by non-keratinized squamous epithelium whose function is protective and lubricant.

Answer:
more active transport occurs in cell A then cell B
Explanation:
hope this helps ;)
The possible conclusion that can be made drawn about the activity of these two cells is that more active transport occurs in cell A than in cell B. The correct option is B.
What is transport?Active transport is a type of transport that cells use to move molecules up and down cell membrane concentration gradients.
Moving actively is carried out using a variety of membrane proteins known as carrier proteins that are connected to an energy source, such as ATP, for example.
The energy needed to move molecules or ions up or down a concentration gradient is provided by the hydrolysis of ATP during this process, known as active transport. The other transport is passive transport, which is reverse.
Therefore, the correct option is B. more active transport occurs in cell A than in cell B.

which mechanism of action is being described when an antibiotic drug causes the destruction of bacterial cell walls
The mechanism of action described when an antibiotic drug causes the destruction of bacterial cell walls is NONSELECTIVE INTERACTION. These drugs do not interact with specific molecules.
Nonselective drugs are involved in nonselective interactions, i.e., they act on a variety of receptors and/or enzymes.
Nonselective drugs can target different cellular structures (e.g., bacterial cell walls) and/or metabolic processes.
For example, Phenocybenzamine is a nonselective drug that can affect different receptors, which is used for the treatment of high blood pressure and sweating associated with pheochromocytoma.
Conversely, enzymes are biological catalysts that speed up chemical reactions by selectively interacting with specific ligands (i.e., substrates).

Life on earth is incredibly diverse. Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms. Life on earth is incredibly diverse. Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms; the genes they contain; and the ecosystems they form on land and in water. Biological diversity is constantly changing. The source of this diversity is evolution, the process of gradual change during which new species arise from older species. Evolutionary biologists study the evolution of living things in everything from the microscopic world to ecosystems. There are so much duversity in life on the Earth because there are great numbers of species on the earth, the present day organism are the end product of about 3.5 billion years of organic evolution on earth.

If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is:
Answer:
It is dominant over "dwarf plant."
Explanation:
If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is it is dominant over "dwarf plant."
What is dominant traits?Dominant traits are always explained when the related allele has dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
The frequency of expression of dominant and recessive traits can be Dominant traits = always / Recessive = sometimes.
According to the question if there is self cross TT×tt then there is TT, Tt, Tt and tt, which means there is a 75% possibility of dominant trait and 25% recessive.
A dominant trait has an inherited trait or characteristic that appears in an offspring and covers the effects of another allele and/or prevails or exhibit its trait above another.
Therefore, If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is it is dominant over "dwarf plant."

4. Which areas seem to be most highly and quickly affected by a continued increase in
carbon emissions?
Answer: The atmosphere will be hit hardest by the increase in carbon. As the amount of carbon increases, it leads to increased warming of the atmosphere. Rising temperatures also increase the rate of evaporation, creating a more humid atmosphere and creating a virtuous cycle of warming.
This increase is beneficial as the Earth freezes due to the absence of carbon dioxide and other greenhouse gases in the air.

Which Organelle assembles amino acids to create proteins?
A. Ribosome
B. Lysosome
C. Chrolorplast
D. Cell membrane
The answer should be A - Ribosome because during protein synthesis, ribosomes assemble amino acids into proteins and ribosome’s are the cellular structures responsible for protein synthesis.
hope this helps!
Ribosomes assembles amino acids to create proteins. The correct option A.
Ribosomes are the organelles responsible for assembling amino acids to create proteins in cells. Ribosomes are composed of RNA and proteins, and they exist either freely in the cytoplasm or attached to the endoplasmic reticulum (ER).
During protein synthesis, the ribosomes read the genetic information encoded in mRNA (messenger RNA) and facilitate the process of translation. Transfer RNA (tRNA) molecules transport amino acids to the ribosomes, where they are joined together in the correct sequence to form a protein chain.
Thus, the ideal selection is option A.

which transcription factor binds directly to the tata-box sequence?
The transcription factor that binds directly to the tata-box sequence is TFIID. This transcription factor (TFIID) is a macromolecular protein complex.
The TATA box is a fundamental nucleotide gene sequence that forms the eukaryotic core promoters, which are required to initiate transcription.
TFIID is a macromolecular protein complex (also called the RNA polymerase II preinitiation complex), which acts as a general transcription factor during the initiation of eukaryotic transcription.
TFIID recognizes and binds to the TATA box (core promoter) and also binds with different activator and repressor proteins in order to regulate the transcriptional activity.
