When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this description, in which two ways is energy conserved when people run?
1. Heat energy is released from the body to the surroundings.
2. Heat energy is taken from the surroundings to the body.
3.Chemical energy is converted to mechanical energy that’s used for muscle movements.
4.Radiant energy is converted to mechanical energy that’s used for muscle movements.
5.Heat energy is converted to mechanical energy that’s used for muscle movements.
When we run, we sweat, which means we're getting hotter and hotter and our bodies need to cool down, which they do through transpiration (sweating). If we need to cool down, we need to release the heat that is in our bodies.
To run, we also need to move our muscles, which requires a specific type of energy, called mechanical or kinetic energy, which is the "energy of movement". In our bodies, we don't store that type of energy though, so we have to convert chemical energy to mechanical energy.
Answers:
⭕Heat energy is released from the body to the surroundings.
⭕Chemical energy is converted to mechanical energy that’s used for muscle movements.
Answer:
Heat energy is released from the body to the surroundings.
Chemical energy is converted to mechanical energy that’s used for muscle movements.

Explanation:
How many genders are there?
Answer:
Nobody really knows how many genders there are.
Explanation:
It widely depends whether you're referring to actual genders or gender identity types. Even then, though, there is not a definite or limited amount of either. For more clarification about the differences...
Gender identity types include: transgender, nonbinary, agender, demigender, etc.
These are not genders because they don't specify what you identify as, they are simply stating that you do not identify with your sex at birth. Don't call these genders, because that would be putting agender and nonbinary people into a binary.
Actual genders include: two-spirit, pangender, polygender, etc.
These are GENDERS rather than gender identity types because they somewhat specify what you identify as.
To say that there are only two genders is incorrect, as gender is a social construct. That does not mean it's useless, it just means that it wasn't constructed correctly because nobody knows for a fact how many genders and gender identity types there are and we probably never will because it's based on one's individual feelings.
Answer:
alot. if you are talking about what you are born with (sex) then there is 3. which is male, female, and intersex. GENDER is completely different. there is too many that i can even say but you can be a girl, a boy, somewhere on the non-binary spectrum (non-binary, demigender, agender, gender fluid, ect), ect.

Which of these organisms will be hunted more often by predators when the corn is infected by fungus?
A. Grass
B. Owl
C. Rabbit
D. Snake
Answer:
A. Grass
Explanation:
In their natural habitat, organisms feed on one another in a relationship called PREDATION. Predation involves two organisms; one called the PREDATOR (the organism that eats) and the other PREY (the organism being eaten).
Organisms preying on one organism will naturally opt for a substitute once the previous prey is no longer accesible. This is the case of a fungus-infected corn that is no longer edible for predators. Hence, the predators will hunt similar feed, which is GRASS in this case.
↬Define a Cell in Biology.
The cell is the basic structural, functional, and biological unit of all living organisms.
The structural and essential component of life is the cell. Cell biology is the study of cells, including their fundamental makeup and the purposes of each of their organelles.
The first biologist to discover cells was Robert Hooke. Cells make up every living thing. They could consist of several cells (multicellular) or just one cell (unicellular) (multicellular).
The tiniest cells known to science are mycoplasmas. All living things are constructed from cells. They give the body structure and turn the nutrients from the diet into energy.
Complex cells conduct a variety of tasks for an organism's parts. They resemble masonry bricks in that they come in a variety of sizes and forms.

How the cancer is diagnosed?
Doctors normally need to do a biopsy to diagnose cancer :)
A biopsy is a procedure in which a doctor will give a sample of client's tissue to a Pathologist who examines it with a microscope and runs tests based on the sample.
Answer:
If you have a symptom or a screening test result that suggests cancer, your doctor must find out whether it is due to cancer or some other cause. The doctor may start by asking about your personal and family medical history and do a physical exam.

Answer:
I don't know your reasons on how you would feel about becoming an astrobiologist but this is what I found and my feelings.
Explanation:
The Perseverance twin is called Optimism. This has all of the same electronics as Perseverance and it’s important to have a twin so that they can test things before they operate Perseverance. When they do land on Mars they need the twin to test out all of the sequences and plan that they have for the rover before they send them up to Perseverance on the surface of Mars. Also, if they have a problem with Perseverance it gives them a place to practice how they recover from that problem.
Personally, for me, I would not like to become an astrobiologist. I like science but not that much. I like the simple questions of why and how does it work. I’m not entirely sure that we as humans are meant to be on any other planet except earth. Earth has been here for many many years and seems to reset itself. I don’t care why and will never know why in my lifetime. I’s just not something that I like to considerate doing as a career.
NASA is targeting no earlier than April 8 for the Ingenuity Mars Helicopter to make the first attempt at powered, controlled flight of an aircraft on another planet. Before the 4-pound (1.8-kilogram) rotorcraft can attempt its first flight, however, both it and its team must meet a series of daunting milestones.
Ingenuity remains attached to the belly of NASA’s Perseverance rover, which touched down on Mars Feb. 18. On March 21, the rover deployed the guitar case-shaped graphite composite debris shield that protected Ingenuity during landing. Ingenuity is battery powered and completely sef recharging from the solar panel on the top. The rover currently is in transit to the “airfield” where Ingenuity will attempt to fly. Once deployed, Ingenuity will have 30 Martian days, or sols, (31 Earth days) to conduct its test flight campaign. All data and pictures will be transmitted to Perseverance and then uploaded for all to see.
Innate immunity ________. is found only in vertebrates is the first, and most general, mechanism of protection against pathogens depends on an infected animal's previous exposure to a pathogen is based on recognition of antigens that are specific to a pathogen
Answer:
is the first, and most general, mechanism of protection against pathogens
Explanation:
Innate or natural immunity is one of the two types of immunity an organism can possess (the other being; acquired immunity). Innate immunity is the FIRST defensive response of an organism against pathogenic attacks. The acquired immune system is only activated when the innate immune system has been penetrated or surmounted.
For example, the skin, mucus secretion, inflammation etc. are all natural or innate defenses against foreign invaders. Therefore, according to this question, innate immunity the first, and most general i.e. commonly used, mechanism of protection against pathogens.

PLEASE HELP!!!! You are a scientist tasked with writing a journal article on the evolution of alligators. In 3–5 sentences, describe the different forms of evidence you might use to analyze the evolution of alligators.
Answer:
The first alligator ancestors evolved about 245 million years ago.
Explanation:
The first alligator ancestors evolved about 245 million years ago due to change in the environmental condition. crocodilians appeared about 80 million years ago during the Cretaceous period. Modern alligators has experience less changes which is closely related to their ancient ancestors and look much like to their relatives that exists about 80 million years ago. The main reason for the change in the body structure of alligator is due to change in environmental condition.
The evolution of alligators can be analyzed by sequencing samples of different species and then producing a bioinformatic analysis.
What is evolution?Evolution means descendence with some class of modification in offspring (phenotypic, genetic, etc).
Evolution can be analyzed by sequencing and comparing the linear order of nucleotide sequences between different species.In conclusion, the evolution of alligators can be analyzed by sequencing samples of different species and then producing a bioinformatic analysis.

Explanation:
Oxygen atoms are different from the atoms of every other elements (true or false)
false I think, but I don't know for sure
Answer:
True
am not sure but my explanation:
An oxygen atom possesses 8 protons, 8 massive, positively charged nuclear particles. There are also 8 massive, neutrally charged nuclear particles, 8 neutrons in the common isotope, 16O. And orbiting the nuclear core, there are 8 electrons, fundamental particles with negligible mass that each possess a formal negative charge.
Any atom with 8 protons is automatically an oxygen atom by defintion. 7 protons specifies a nitrogen atom; 9 protons specifies a fluorine atom. Of course, oxygen generally takes the form of the dioxygen molecule, O2. The number of protons gives Z, the atomic number, which is different for each element.
