ATP allows for crossbridge reformation by breaking the myosin and actin crossbridge. So the correct answer is d) atp
When ATP is bound to myosin head, and the myosin, cross bridges between actin and myosin are broken up, releasing ADP and P1, and the muscle returns to its relaxed condition. The myosin globular head, which extends from a myosin filament in muscle, is held to momentarily bind to a nearby actin filament and bring it into the A band of a sarcomere between the myosin filaments to form a cross bridge.

Spider silk is a material made of proteins that has a strength per gram that is five times that of steel. One feature of some of the toughest spider silks is a high proportion of β sheets that stack tightly together to form crystal-like arrays. Which amino acids would you expect to be common in such crystalline stacks and why?
Answer:
glutamic acid, because the R group could form ionic bonds
arginine, because the R group could form ionic bonds
tryptophan and tyrosine, because the R groups are small, allowing close stacking
glycine and alanine, because the R groups are small, allowing close stacking

What is the difference between flu viruses and the measles virus?
Answer:Influenza and measles are viruses that both cause respiratory symptoms. The typical measles rash does not appear for 2-4 days, so during influenza season, symptoms of early measles can be confused with influenza.
Explanation:
Explanation:
Vaccines for both measles and flu already exist, however the flu vaccine must be updated because of the virus's ability to change and adapt in order to invade cells in the human body. The goal of researchers was to find genes in each virus that cannot survive changes.
By comparing two similar viruses which attack the body in similar ways through the lungs, researchers confirmed that the measles virus is much less open to evolutionary change by using an experimental technique called insertional mutagenesis to change the genes of each virus.
How does an organism obtain C6H12O6 and O2 to
undergo respiration?
Answer:
oxygen is given off during photosynthesis as a waste product
Explanation:
this is something that only plants and some algae and bacteria can do. they take sunlight and combined C02 and H20. they create glucose (C6H1206) and oxygen gas (02).

Conditions for Hardy-Weinberg equilibrium Conditions for evolution to occur
Answer: CONDITIONS FOR HARDY
No mutations should appear in the beetle population because new alleles would change the allele frequencies
There should be random mating among beetles
There should be no natural selection on the beetle population
The population of beetles must be large enough so that genetic drift is avoided
There should be no migration of beetles into or out of the population.
CONDITIONS FOR EVOLUTION-
Natural selection favors green beetles
Purple mutants appear among the Beatles
Preferred mates are red, so these individuals reproduce
Large numbers of brown beetles were killed in a forest fire
A significant number of yellow beetles left.
Explanation: I only added about half the sentence of each answer because it’s to long.

How many times more erosion occurs in a soil with 3% moisture than a soil with 7% moisture is a 15 m s-1 wind?
Answer:
Twice.
Explanation:
If a soil with 3% moisture has twice the rate of erosion as compared to the soil having 7% moisture if both experience same speed of wind i. e. 15 m/s. This is because moisture held the particles of soil tightly with each other and prevent erosion in the soil so if the moisture becomes half in the soil then the rate of erosion is twice or doubled at constant wind speed.

Reproduction is not a life process still organisms spend a lot of energy on it. Give reason.
Answer:
Reproduction is not a life process, but still organisms spend a lot of energy on it. ... The reproduction is not necessary to ensure living but it is required to ensure that the continuation of the living organisms and generations of the next cycle of living. It is necessary for ensuring the stability of the population.
Reproduction also helps in increasing the population of the species. All the processes which are necessary to maintain life in an organism are called life processes. Reproduction is not considered a life process because it is not necessary to maintain life.

What are ethical concerns in using animals for research?
Select all that apply.
Animals cannot consent to being used in experiments.
Animals are ideal biological models for experiments
Many animals can be studied at one time.
Some animals may have adverse reactions.
Answer: Animals cannot consent to being used in experiments.
Explanation:
Animals are not suitable options for the biological research as they are getting extinct and their population size is getting decreased. Option A is correct.
What are extinct species ?These are the species that are getting diminished from planet because of certain factors such as loss of habitat and many other crucial factors that affecting their growth.
Animals can not be used in the biological research as they are not able to speak the language which is understood by humans and ideally it is not right to do dissection over living beings.
Animals earlier were definitely considered for the experiment but the awareness of ethics and sensitivity of the issues is bringing down the ban on the animal crimes along with the lab research.
Ethical concerns are as well that without God's permission it is not right to harm the living beings.
Therefore, option B is correct.

1. What are the different properties of light that apply to the image formation of
optical devices such as mirrors and lenses?
Answer:
Optical instruments are based on optics. They use mirrors and lenses to reflect and refract light and form images. The light microscope and telescope use convex lenses and mirrors to make enlarged images of very tiny or distant objects. A camera uses a convex lens to make a reduced image of an object.
The property of light that is important to the image formation in mirrors is reflection. The property of light that is important in the formation of an image by lenses is refraction.
Light refers more specifically to the portion of the electromagnetic spectrum that is perceivable with the optical eyes. There are several properties of light such as reflection, refraction, diffraction, interference, etc.
