Answer:
The correct answer is option A. binding of a new molecule of ATP.
Explanation:
Actin and myosin are complementary filaments present in muscle, actin is thin and myosin is a thick filament, these two filaments are responsible for the movement by muscle contraction and relaxation. Actin and myosin head shows great affinity towards one another.
Myosin heads are tightly attached to neighboring actin thin filaments due to its affinity to actin, however, myosin at other pockets also show a huge affinity for ATP. If myosin is bound to actin the affinity for ATP is changed and if new ATP bounds to the empty pockets it changes the conformation of myosin and prevents lockup or binding of the actin-myosin protein.

Which of the following would a lipid most likely do in the body?
А. provide quick energy for exercise
B. store genetic information
С. build muscle tissue
D. store energy for later use
Answer:
D
Explanation:
Lipids have a carboxyl group at one end, a methane group at the other, and a long hydrocarbon chain in between. This structure makes it suitable for long-term energy storage. Quick energy is usually provided by carbohydrates. Nucleic acids store genetic information, and muscle tissue is made up of muscle cells.
The most likely function of a lipid in the body is the storage of energy for later use. Choice D.
Although, lipids are a good source of energy with about 9kcal of energy supplied per gram.
Lipid metabolism to provide quick energy is quite a slow process as opposed to carbohydrates which provide quick energy for exercise and other tasks.
Nucleic acids are responsible for storing genetic information.
Muscle tissues are built by muscle cells.
As lipids are a high energy yielding source, lipids are responsible for storing energy for later use.

Answer:
The correct answer is - reflexive actions controlled by the spinal cord.
Explanation:
Digestion and breathing are examples of involuntary action which is controlled by the autonomic nervous system of the CNS. however, the part of the nervous system that controls is the spinal cord and hind brain by the spinal reflex actions.
These are the action they do not require any thought and work without any thought that leaves the brain for other actions and coordinations. specific but the same stimuli causes the response in the same way.
5. Some advantages of sexual reproduction include: (select all that apply) *
a.genetic variation
b.improves chances of adapting to the envionment
c.helps species survive catastrophes
d.Certian genes work beter than other
Some advantages of the sexual reproduction include genetic variation. Genetic variation results into changes in the genetic material (DNA). Thus, the correct option is A.
What is Genetic variation?Genetic variation is the difference in the DNA (deoxyribonucleic acid) among individuals or the difference between different populations. The multiple sources of genetic variation include mutations and genetic recombination. Mutation is the changes in the genetic material of an organism which are the ultimate sources of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Genetic diversity is important because it gives the species a better chance of survival through variations. However, the genetic diversity can be lost from the species when the populations get smaller and isolated from each other, which decreases a species' ability to adapt and survive better in the condition.
Therefore, the correct option is A.

2.producing delicious and good fruits for animals protect and help them to spread. delicious food attract animals like birds and other animals who are feed on them. when they eat the fruits and the seeds pass by unharmed. these way the seed dispersal occur of a plants.
Seed dispersal is a movement transport and spread of the seeds away from the parent plants. As plants have very limited mobility and transportation also includes some of the abiotic factors.
Winds, waves, gravity, and many more abiotic form of seed seed dispersal have been found. The biotic forms of seed dispersal include man, animals and birds. The more delicious is the plant the more is the chance of seed dispersal and hence is an added advantage to the plants. The seeds remain unharmed and many animals like to feed on them.Learn more about the living (biotic) and non-living (abiotic) means of seed dispersal.

Which mutation below would result in the greatest amount of change in the proteins that code for a particular trait?
(Please help I will reward)
A. inserting three nucleotides
B. deleting three nucleotides
C. deleting one codon
D. deleting two nucleotides
Answer:
Mutations are errors in codons caused by changes in nucleotide bases. Some mutations may not have much effect. For example, if the codon GAA becomes the codon GAG, because the genetic code is degenerate, the codon will still code for the amino acid glutamate. Such ineffectual mutations are called silent mutations. Some mutations, however, can have a huge affect on coding for amino acids, which can in turn affect what proteins are produced, which can have a profound effect on cellular and organismal function.
T/F Osmosis and diffusion are both examples of passive transport.
A.True
B.False
Both osmosis and diffusion are passive transport processes, meaning that no additional energy is needed for them to take place. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.
The given statement "Osmosis and diffusion are both examples of passive transport" is True.
Passive membrane transfer methods are the most direct. Passive transport is a phenomena that happens spontaneously and doesn't require the cell to use energy to move. Diffusion is the process by which chemicals travel passively from a region of higher concentration to a region of lower concentration. A concentration gradient is a difference in the concentration of one substance throughout a physical region.Transport that is done passively is called diffusion. Until the concentration is the same across the space, a single substance has a tendency to travel from an area of high concentration to an area of low concentration.Based on the gradient of water concentration across the membrane, osmosis is the mechanism by which water diffuses through a semipermeable membrane. Osmosis moves just water across a membrane, and the barrier restricts the diffusion of solutes in the water, whereas diffusion distributes material across membranes and into cells.Learn more about the passive transport with the help of the given link:

Answer:
The nucleus is like the principal of a school, the cell membrane is like a school building, and the mitochondria is like the staff in a school.
Explanation:
Definitions:
The nucleus of a cell contains the majority of the cell's genetic material, and coordinates cell activities like protein synthesis and cell division.The cell membrane is the semipermeable membrane of a cell that surrounds the cytoplasm (the material inside the cell other than the nucleus).The mitochondria is "the powerhouse of the cell", because it produces most of the chemical energy needed to power the cell's chemical reactions.The nucleus is like the principal of a school: the nucleus controls the cell, much like how the principal controls the school.
The cell membrane is like a school building: the cell membrane forms a boundary between the cell and outside environment, much like how the school building separates you from outside.
The mitochondria is like the staff in a school: the mitochondria powers the cell, much like how the staff in a school keep the school running.

Answer
The Channichthyidae fish, also known as the
crocodile ice fish, lives in the Southern Ocean
around Antarctica. These waters are known to
maintain extremely low temperatures all year,
ranging from approximately 28°F to 35°F. These fish
have adaptations that allow them to live in cold, low
oxygen waters. (a) If you were to examine the
membrane lipid composition of cells from the
Channichthyidae fish identify what you would
expect to find. (b) Justify why you might find what
you identified in part (a).
A) If you were to examine the membrane lipid composition of cells from the Channichthyidae fish, what you would expect to find is glycoprotein,zona pellucida protein and a less number of haemoglobin that is found in this type of fish.
B) Justification of why you might find what was identified in part (A) is because;
Glycoprotein contains antifreeze compounds,these antifreeze compounds are what provide resistance to freezing of their hypoosmotic tissues by the subzero environment.
If we analyzed the lipid composition of these fish, we could find glycoproteins.
We can arrive at this answer because:
Glycoproteins are formed by a chain of oligosaccharides, linked to a chain of polypeptides, which are side chain lipids.These glycoproteins have different functions in the body.One of the most important functions is keeping the heat.This function allows heat to remain longer in an organism and heat loss to be slower.In this case, the glycoprotein is an essential molecule in the organism of living beings that live in environments with very low temperatures, such as fish Channichthyidae.

The sequential series of nucleotide triplets that are positioned in the A site of the ribosome during translation. A. Primary structure B. Exons C. Promoter D. Reading frame
Answer:
The correct answer is D.
Explanation:
Reading frame is a sequence of codons determined by nucleotides that are read in groups of three from a specific translation start codon, that is, it is a linear sequence of codons or triplets in a nucleic acid. It is one of three possible reading alternatives of a nucleotide sequence of a series of triplets, this means that, in a double-stranded DNA molecule, there are 6 possible directions in which reading frames can be opened; three in the forward direction and three in reverse.
