D. The molecule has an OH group on the end.

Answers

We know the molecule below is an unsaturated fat because the molecule contains carbon double bonds.

What is an unsaturated fat in molecule?

An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fat molecule made of chains where some carbon atoms are not fully saturated with hydrogen atoms.

Unsaturated fat, a fatty acid in which the hydrocarbon molecules have two carbons that share double or triple bond and are therefore not completely saturated with hydrogen atoms. Due to the decreased saturation with hydrogen bonds, the structures are weaker and are, therefore, typically liquid at room temperature.

Unsaturated fats are either monosaturated fats, as in olive or canola oils, or polyunsaturated fats, as in nuts, seeds, and seed oils

The correct answer is option A.

Which statement best supports the theory that eukaryotic cells evolved
through endosymbiosis?
A. Eukaryotic cells can eat prokaryotic cells by engulfing them with
cell membranes.
B. All prokaryotic cells are covered by a stiff cell wall that protects
them.
C. Their chloroplasts contain DNA that is similar to that of
prokaryotes.
D. Chains of amino acids form inside tiny bubbles filled with organic
molecules.

Answers

Answer:

Their chloroplasts contain DNA that is similar to that of

prokaryotes

Explanation:

This is based on the theory that the membrane bound organelles of chloroplast and mitochondria  which are peculiar to Eukaryotas evolved from bacteria by endosymbiosis. Thus bacteria contain the DNA of these organism Evidently, these organism (Eukaryotas) must have cohabited  with bacteriA some time ago

Why are fossil fuels considered nonrenewable resources?

A. They take millions of years to form.
B. They cannot be used to create electricity.
C. They form quickly due to decaying biomass.
D. They require both sunlight and water to form.

Answers

The answer is A it takes a million of years to form

Fossils fuels take millions of years to form which are considered nonrenewable resources. So, the correct option is A.

What are Fossils fuels?

A fossil fuel is defined as a hydrocarbon-containing material which forms naturally in the earth's crust from the remains of dead plants and animals that is extracted and burned as fuel where as the main fossil fuels are coal, oil and natural gas.

Fossil energy sources include oil, coal and natural gas, are non-renewable resources that formed when prehistoric plants and animals died and were gradually buried by layers of rock. Fossils fuels take millions of years to form which are considered nonrenewable resources.

enzymes are macromolecular biological catalysts. enzymes accelerate chemical reactions. almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life. without them life on earth would probably not exist. identify two factors that can affect the structure and function of an enzyme and describe what causes the change to occur. course hero.

Answers

Answer:

Enzyme is a catalyst

Explanation:

Enzymes make the chemical reaction faster than usual because the activation energy required for a substance to react becomes low with presence of enzymes. if we don't have enzymes it may result to slow metabolic processes. some environmental factor can affect enzymes like over exposed to radiation can activate the enzyme causing it to disrupt. or consuming a mutagenic agents that may affect the enzymes activities.

a. ecosystems
b. habitat
c. abiotic factors
d. biotic factors

Answers

Abiotic factors. They are not living yet control the plant’s well being.

Abiotic factors are non-living components of an ecosystem that influence their surroundings. Examples may be light, water, and temperature in a terrestrial habitat, hence option C is correct.

What are abiotic factors?

Abiotic variables are non-living elements that have an impact on the survival, development, and existence of living things, including plants.

We may concentrate on the water as one of these abiotic elements even though there are many others that are equally significant and have a part to play.

Water is one of, if not the most, critical abiotic factors since it is essential for plant existence. Depending on how severe the absence of water is, it will be a limiting factor for a plant's growth or even life.

Therefore, abiotic factors are non-living components of an ecosystem that influence their surroundings, hence option C is correct.

.Specific processes must take place within the cell for protein synthesis to occur. The processes that take place within a cell for protein synthesis to occur. Which occurs during translation but not during transcription? A DNA template is used to create an mRNA strand. A tRNA template is used to create a DNA strand. A tRNA template is used to create an mRNA strand. An mRNA template is used to create an amino acid chain.

Answers

Answer:

An mRNA template is used to create an amino acid chain.

Explanation:

Transcription is the first step in the protein synthesis process. Translation is the second.

Overall, the central dogma of biology is DNA->RNA->protein.

Transcription is that first step, DNA to RNA, and translation is RNA to protein: think of it like nucleic acids can just be transcribed, but nucleic acid to protein is like a whole different language, so it has to be translated. So the correct answer here is that mRNA is used to make amino acid chain (aka protein), which happens only in translation.
