Answer:
C. 2 one muscle contracts while the other muscle relaxes and becomes longer
Explanation:
hope this helps :))
The minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.
What are Muscles?Muscles may be defined as the bundles of fibrous tissue in animals including humans which consist of long cells that contract when stimulated and induce movements.
Muscles play numerous roles such as maintaining the overall posture of the body, moving the skeleton, storing nutrients, providing stability, assisting respiration and digestion, etc.
A joint is migrated with the cooperation of two muscles in such a way that one provokes the contraction while the other induces relaxation at the same time. This simultaneous activity of both two muscles is responsible for the proper migration of joints.
Therefore, the minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.

What are some types of biotechnology??
Answer and Explanation:
There are a few different types of biotechnology.
One is medical biotech. Essentially, this branch is used to help improve the wellbeings and helaths of people. It involves a lot of DNA in helping to find cures for various diseases. Some examples of advancements in this field are vaccines and antibiotics.
Another is agricultural biotech. In the agriculture industry, farmers are continuously searching for ways to increase crop yield and quality, which delves into the topic of genetic modification and engineering. For example, scientists are breeding certain plants or adding certain genes to make offspring that is hardier and more pest-resistant.
Those are two main types of biotechnology.

In a desert ecosystem, coyotes and rattlesnakes both eat the same type of mouse as a primary part of their diets. Recently, coyotes have been hunted and killed by people, decreasing the overall coyote population. How will this most likely affect the rattlesnake population over time?
Answer:
Answer: It will increase because coyotes are the competition.
Explanation:
An ecological niche can be defined as the functional role which an organism performs in the ecosystem in order to sustain it's life. The functional roles include how an organism obtains it's food, type of food eaten by the organism, type of habitat chosen by the organism and type of breeding season used by the organism.
In the given situation, both coyotes and rattlesnakes are dependent upon the same ecological niche that is they are dependent upon mouse as a primary part of their diets. As, both coyotes and rattlesnakes are dependent upon the same diet there may exist the competition between the two species. But it is mentioned that the coyote population is decreasing therefore the population of rattlesnake will most likely increase as the competition for the same diet decreased.

Identify the types of breezes and the areas of high and low pressure that cause them.
Answer:
There are 4 types of breezes: land breeze, sea breeze, mountain breeze and valley breeze.
The breeze will originate from an area of high pressure and travel towards/blow in the direction of the area at a lower pressure.
In each case, the name of the breeze indicates where the breeze is blowing from. For instance, the land breeze will blow from the land (at high pressure) to the sea (at lower pressure). A mountain breeze will blow from mountain (at high pressure) towards the valley (at low pressure).

Help please! I will give brainly! The prefix aqua- refers to ""water."" The verb culture means ""to foster the growth of living things."" Use this information to define aquaculture.
Answer: im not sure but i think it means to grow plant because it is talking the key words are to foster the growth of living things.
i hope it is right if not sorry!!!!!!!!!!!!!!!!!!!!!
Answer:
Aquaculture means to foster organisms (for the most part fish) that live in water.
Explanation:
After reading Holt Enviromental Science's Food and Agricultural Section: Animals and Agriculture passage, you can define aquaculture. In the passage it reads "fish farms generally consist of many individual ponds that each contain fish at a specific stage of development." The fish grow until they are matured and then "they are harvested."

In the gradualism model, species change _____ over time. Evidence for intermediate changes in species' characteristics is_____ . In the punctuated equilibrium model, changes can be rapid followed by periods ______of change. Evidence for intermediate changes in species' characteristics is _____
Answer:
In the gradualism model, species change slowly over time.
Evidence for intermediate changes in species' characteristics is anagenesis.
In the punctuated equilibrium model, changes can be rapid followed by periods of steady change.
Explanation:
Gradualism theory states that the evolutionary processes imply slow, uniform and gradual transformations. This type of evolutionary theory is referred to as anagenesis, where branches are not observed during the evolution of populations. On the other hand, the punctuated equilibrium theorizes that the evolutionary processes are characterized by sudden modifications that are followed by periods without changes. It is likely that both processes may drive evolution of species.
Answer:
gradually, present, little, absent.

Q. Describe the double circulation in human beings.
Answer:Double circulation has two components, pulmonary circulation and systemic circulation. Pulmonary Circulation : It is movement of blood from heart to the lungs and back. Deoxygenated blood of the body enters the righ auricle, passes into righ ventricle which pumps it into pulmonary arch,...
Explanation:
Answer:
During a single cycle blood goes twice in the heart which is known as double circulation. It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system more efficient and helps in maintaining constant body temperature. During a single cycle, the blood goes twice in the heart. This double circulatory system is important because it ensures provision of oxygenated blood to the muscle and not a mixture of oxygenated and de-oxygenated blood. Hence, this system ensures efficient supply of oxygenated blood to the muscles.

Your friend has a dog with fleas. She goes to the pet store and buys over-the-counter flea medicine. It does not work. So she goes to the veterinarian and explains that she just spent $80 on medicine that does not work. The vet casually says, “Oh yeah, that medicine does not work anymore.” Because you now understand natural selection, your friend asks you questions. Answer them with evidence.
- What do the resistant fleas do that the sensitive fleas do not?
Answer:
Explanation:
The dog has fleas, but the medicine to counter this does not work. This means that the fleas have built up a resistance against the drug to ensure continued survival and reproductive success of these organisms. These resistant fleas may have existed in population as the population is always large but in small amounts. Thus, treatment with the drug will lead to the dieing out of the sensitive fleas and then leaving the resistant fleas with the favourable alleles to be selected for.
These favourable traits that have evolved against the drugs are then selected for and the organisms reproduce giving rise to more fleas with these favourable characteristics (being resistant to the drugs) such that their continued survival and reproductive is ensured compared to the sensitive fleas that die out.
Crossing-over can happen at any location on homologous chromosomes. The farther apart two genes are, the more likely that crossing-over would separate them.
On these chromosomes, which pair of genes would be most likely to be separated by crossing-over: A and B, or A and C? Why?
Answer:
The answer is C I believe. Chromosomes usually make a pattern and thats the points were it would make a pattern.
~Paige~Crossing-over chromosomes.
The crossing of the chromosomes is the swap or the exchange of genetic materials. It takes place in the germline, at the formation of the egg. This is also called meiosis. It aligns with DNA sequencing. The pried chromosomes cross over the other.
Thus the answer is they make a pattern that points in the pattern.
This shows the crossing happens at the homologous chromosome. The farthest apart two genes the most likely they cross each other that would separate them. Thus the option C is correct. They cross at the end., hence is a process called recombination.Learn more about the chromosomes.

Explanation:
the diagram shows three steps in the clotting process.
Which lists the clotting process in the proper order?
o А, С, В
ОВ, А, С
o С, А, В
е В, С, А
Answer:
В, С, А
Explanation:
The process of clotting is known as the hemostasis which takes place in three steps: the vascular spasm, the formation of a plug of platelets and the coagulation.
In the given question, step B shows the process of vascular spasm in which the vascular blood vessels becomes constricted due to injury. After this, the platelets present in the blood starts accumulating at the site of injury. These platelets stick together and form a plug-like structure at the site of injury.
Later, step A takes place that is fibrin protein present in the blood starts forming a mesh-like structure which does not allow the bleeding and this process is known as coagulation.
Thus, the selected option is the correct answer.

Food molecules such as proteins cannot be absorbed unless they are digested.
Give one reason why.
Answer:
Your body can't absorb proteins in their natural state. Certain proteases in your stomach and pancreas break the bonds that hold the amino acids in protein together so your body can absorb the composite amino acids individually.
Food molecules cannot be absorbed unless digested because ; They are too big to pass through the plasma membrane, in their natural state.
The food molecules such as protein needs to be broken down into its composites amino acids for easy absorption. food molecules, cannot be absorbed in their natural state because they are too big to pass through the plasma membrane.
Protein is broken down ( digested ) by proteases and pancreas into composite amino acids that is absorbable into the human cells.
Hence we can conclude that protein cannot be absorbed unless digested because they are too big to pass through the plasma membrane, in their natural state.

Describe the sequence of events during a blood clot.
Answer: Hemostasis includes three steps that occur in a rapid sequence:
Explanation: 1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels; (2) formation of a platelet plug; and (3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot.
or:
The Blood Clotting Process
Injury. A small tear in a blood vessel wall (for example, from a cut on the skin or an internal injury) causes bleeding.
Vessel constriction. To control blood loss the blood vessel narrows (called constriction), thus limiting blood flow through the vessel.
Platelet plug. ...
