Chemosynthesis _______. Question 11 options: uses energy derived from hydrocarbons and hydrogen sulfide in place of solar energy produces carbohydrates and sugars occurs around hydrothermal vents near the oceanic ridge system Both a and c are correct. All of the above are correct.
Answer:
The answer is all of the above are correct.
Explanation:
Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways. For example, at hydrothermal vents, bacteria oxidize hydrogen sulfide and add carbon dioxide and oxygen to produce sugar, sulfur, and water:
CO2 + 4H2S + O2 ⇒ CH20 + 4S + 3H2O.
Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. During chemosynthesis, bacteria living on the seafloor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in seawater). Pure sulfur and sulfur compounds are produced as by-products.
Describe hydrophobic interactions, the conditions under which they occur, and the probable influence they have on protein structure. Group of answer choices These are nonpolar side chains of amino acids that tend to associate to form hydrophobic clusters usually away from the protein surface. These are nonpolar side chains of amino acids that tend to destroy hydrophobic clusters away from the protein surface. These are polar side chains of amino acids that tend to associate to form hydrophobic clusters usually close to the protein surface. These are polar side chains of amino acids that tend to destroy hydrophobic clusters close to the protein surface.
Answer:
Nonpolar side chains of amino acids tend to associate to form hydrophobic clusters usually away from the protein surface.
Explanation:
Hydrophobic interactions are defined as the relationship between the low water soluble molecules named hydrophobes and water. They contains a long chain of carbon atoms and are usually considered as a nonpolar molecules.
They occur when the non polar amino acids are associated to produce the hydrophobic clusters that are usually away from the surface of the protein.

Why does climate change affect so many things?
Answer:
These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide (CO2). Global climate change has typically occurred very slowly, over thousands or millions of years.
Explanation:
According to me there are several causes of climate change, but all the problems are based upon a major problem which is over population. Either it is deforestation, any kind of pollution, global warming or whatever it is, all these problems are inter-linked and all are due to increasing population.

What process facilitates locomotion for the ovum?
Question 6 options:
a. Once the ovum leaves the ruptured follicle it is captured by the uterus and then directed into the Fallopian tube, where it is pushed along towards the oviducts.
b. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
c. Once the ovum leaves the ruptured follicle it is fully matured and propels itself into the Fallopian tube, where it moves along towards the uterus.
d. Once the ovum leaves the ruptured follicle it is captured by the cervix and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
The correct answer is B. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
Explanation
Ovulation is a process that occurs during the menstrual cycle that occurs around day 14 of the cycle. In the ovulation process, the eggs go through different places before reaching the uterus (their final destination). The first step is when the egg leaves the broken follicles. The second step is when it is taken to the fallopian tubes (place where fertilization occurs) through the fimbriae. The third step is when the egg uses the cilia to reach the uterus.

Explanation:
If the gene sequence of DNA is A T T C G A C T C G what will the complementary mRNA sequence be that is made during transcription?
Answer:
U A A G C U G A G C
Explanation:
The complementary bases in RNA are the same as DNA with G-C (guanine to cytosine).
But, they are different in that RNA has A-U (adenine to uracil) instead of A-T (adenine to thymine).
Using these RNA base pairs of G-C and A-U, create the complementary mRNA sequence:
A T T C G A C T C G
Translate:
U A A G C U G A G C
So, the complementary mRNA sequence will be U A A G C U G A G C

How do I make a Punnet Square without knowing if traits are Dominant or Recessive? I cannot refer to the parents of the current generation, so I have to rely on that generation to create a theoretical next generation.
If you are referring to a previous generation, that would probably mean that the traits they have are the dominant ones
Explanation:
if you know all the traits possible, then the ones the parents have of a previous generation are most likely the dominant ones, from there, you can hopefully figure out another generation. could you attach a picture if this didn't help? thanks

Explanation:
im megaminds child
Absolute strength measures maximum force. Dynamic strength measures repeated motions. Elastic strength measures exertion of force rapidly. and Strength endurance measures fatigue resistance.
What is Muscle strength ?Physical strength and muscular endurance share some characteristics, they also differ significantly. Your ability to apply force or lift weights is a measure of your muscular strength. Using heavier weights for fewer repetitions helps develop muscular strength.
The term "muscular endurance" describes a muscle's capacity to endure prolonged periods of repeated contractions against opposition.
Long-distance running, cycling, or swimming, as well as bodyweight exercises and circuit training, are exercises that increase muscle endurance.

During a recent hurricane, 25 individuals of the same butterfly species were blown onto a barrier island in southern Florida. Prior to this event, this species did not inhabit the island, but with the ample vegetation on the island and a lack of predators, the displaced individuals were able to survive and reproduce. When the butterflies initially arrived on the island, they did not have to compete for food or space. What type of population growth did they likely exhibit
Answer: Exponential
Explanation:
The main requirement for the population of a species to grow is food. When there is food, a organisms that are born will be able to live longer because food will be able to sustain them.
This is what happened with humans during the Neolithic Revolution when we began farming.
The general trend is that the more food that is available, the higher the population growth. When these butterflies arrived and found no competition for food, their population would increase in the highest way possible which is exponentially because there would be plenty of food to go around.
Answer:
Exponential growth
Explanation:
Without any competition for food or space, the butterfly species likely experienced exponential growth.
The lack of competition would have allowed the population to flourish, as they would have excess amounts of resources, food, space, and other limiting factors.
So, they most likely exhibited exponential growth.
What is a disadvantage of using a space-filling model to show a chemical compound?
Answer:
Explanation:
The appropriate answer is 'space filling models do not identify the number and type of bonds'. A space filling model is one type of three dimensional (3D) molecular model used to represent molecules of different chemical compounds. The structure of this type of arrangement shows that, for example, two elements are bonded but it does not show if it is a single, double or triple bond.

9. UGU-UUC-CCU-UAA
UGU-UCC-CUU-AA
Answer:
7. Substitution mutation
8. Substitution mutation
9. Frameshift mutation
Explanation:
A substitution mutation is any kind of mutation that involves replacement of one or more nucleotide base by another in a sequence.
A frameshift mutation, on the other hand, is a mutation that changes the reading frame of the sequence. Two types of mutations cause frameshift viz: insertion and deletion mutation.
In the following sequences, mutation has occured as follows:
7. UGU-CCG-GAA-CGA to UGC-CGG-GAA-CGA - Substitution mutation has occured because nucleotides C and G has replaced C and U in the first and second codons respectively.
8. GAA-CGU-AGC-GGU to GAU-CGU-AGC-GGU- A substitution mutation because nucleotide U has replaced A in the first codon.
9. UGU-UUC-CCU-UAA to UGU-UCC-CUU-AA - A frameshift mutation because nucleotide U has been removed from the second codon, hence, causing a change in the reading frame.
