State 2 of Newtans three laws
(PLS HELP ASAP!!)
1. Something at rest or in motion in all constants will remain that way unless acted upon by a force.
2. F=ma
Explanation:
Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Force equals mass times acceleration; it states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

what is the importance of predation in an ecosystem
Answer:
Without predatation, things wouldn't eat each other.
Rabbits won't eat grass, Wolves won't eat Rabbits, and so on...
If it were to continue this way there wouldn't be a single animal on this planet. (everything living except plants that only rely on the sun.)
It's a food chain. A CHAIN. Each varible depends on each other.
And a food chain has a direct impact on the ecosystem.
For example:
No rabbits mean there is so many grass and carrots left behind
No wolves means there are too many rabbits
So that means
No wolves
Whatever eats the wolves wont be alive
Whatever eats THAT wouldn't be alive
Clouds form when the water vapor in air condenses as
Answer:
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.

Calculate the kinetic energy of a
30 g bullet fired at 200 m/s.
Step 1: Identify the formula needed to solve this problem.
The formula for kinetic energy (KE) is:
KE = 1/2m~v^2
m = mass
v = velocity
Step 2: Make a list of the values given in the question.
mass (m) = 30 g
velocity (v) = 200 m/s
[tex] \frac{1}{2} m {v}^{2} \\ \frac{1}{2} \times 30 \times {200}^{2} \\ 15 \times 40000 \\ = 600000[/tex]
Answer:
6 × 10⁵ J
Explanation:
Kinetic Energy of a moving mass is defined as, half of the product of it's mass and the square of it's velocity.
[tex] \boxed{ \mathsf{K.E. = \frac{1}{2} m( {v})^{2} }}[/tex]
Mass of the bullet (m) = 30 gvelocity (v) = 200 m/ s[tex] \implies\mathsf{K.E. = \frac{1}{2} \times 30 \times ( {200})^{2} }[/tex]
[tex] \implies\mathsf{K.E. = 15 \times 4 \times {10}^{4} }[/tex]
[tex] \implies\mathsf{K.E. = 60 \times {10}^{4} }[/tex]
[tex] \implies \underline{\mathsf{K.E. = 6 \times {10}^{5} J }}[/tex]

Which type of resources form much more slowly than we use them? A: reusable B: renewable C: nonreusable D: nonrenewable
The type of resources from much more slowly than we use them is non-renewable resource. The correct option is D.
What are nonrenewable resources?A non-renewable resource is a natural resource that cannot be replaced quickly enough by natural means to keep up with consumption.
Carbon-based fossil fuels are one example. With the help of heat and pressure, the original organic matter is converted into a fuel such as oil or gas.
Nonrenewable energy sources are not only affecting our planet's atmosphere by increasing greenhouse gas emissions.
Coal and oil combustion emits particles that can pollute the air, water, and land. Some of these particles are captured and stored, but many are released into the atmosphere.
The use of fossil fuels also disrupts Earth's "carbon budget," which balances carbon in the ocean, earth, and atmosphere.
Thus, the correct option is D.

Based on this diagram label the positive and negative sides of the DNA fingerprint with a + and – sign.
Answer:

Explanation:
What is a DNA fingerprint?
DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA.
Background
Almost every cell? in our body contains our DNA?.
On average, about 99.9 per cent of the DNA between two humans is the same.
The remaining percentage is what makes us unique (unless you are an identical twin!).
Although this might sound like a small amount, it means that there are around three million base pairs? that are different between two people. These differences can be compared and used to help distinguish you from someone else.
Minisatellites are short sequences (10-60 base pairs long) of repetitive DNA that show greater variation? from one person to the next than other parts of the genome?. This variation is exhibited in the number of repeated units or ‘stutters’ in the minisatellite sequence.
The first minisatellite was discovered in 1980.
DNA fingerprinting
DNA fingerprinting was invented in 1984 by Professor Sir Alec Jeffreys after he realised you could detect variations in human DNA, in the form of these minisatellites.
DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual. This is a DNA fingerprint.
The probability of having two people with the same DNA fingerprint that are not identical twins is very small.
Just like your actual fingerprint, your DNA fingerprint is something you are born with, it is unique to you.
How was the first DNA fingerprint produced?
The first step of DNA fingerprinting was to extract DNA from a sample of human material, usually blood.
Molecular ‘scissors’, called restriction enzymes?, were used to cut the DNA. This resulted in thousands of pieces of DNA with a variety of different lengths.
These pieces of DNA were then separated according to size by a process called gel electrophoresis?:
The DNA was loaded into wells at one end of a porous gel, which acted a bit like a sieve.
An electric current was applied which pulled the negatively-charged DNA through the gel.
The shorter pieces of DNA moved through the gel easiest and therefore fastest. It is more difficult for the longer pieces of DNA to move through the gel so they travelled slower.
how can the h. pylori bacteria survive in the human stomach?
Answer:
To survive in the harsh, acidic environment of the stomach, H. pylori secretes an enzyme called urease, which converts the chemical urea to ammonia. The production of ammonia around H. pylori neutralizes the acidity of the stomach, making it more hospitable for the bacterium

If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.
What is the Cell Cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next nuclear division.
There are three major checkpoints in the cell cycle. One at the end of the G1 phase, the second at the end of the G2 phase, and while third is during the M phase.
Therefore, if mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.

helper t cells secrete ________ to stimulate the proliferation of b cells.
Answer:
Helper T cells are activated when they bind to their target antigen being displayed on an antigen-presenting cell. These cells then release what chemical? Cytokines, which is a chemical that signals B cells and other T cells to activate.
Helper T cells secrete cytokines to stimulate the proliferation of B cells.
What are Helper T- Cells?Helper T cells, also known as CD4+ T cells, are a type of white blood cell that play a critical role in the adaptive immune response. They are called "helper" cells because they help activate and coordinate other cells in the immune system, including B cells and cytotoxic T cells, to mount an effective response against a specific pathogen or foreign substance.
Helper T cells recognize and bind to antigens presented by antigen-presenting cells, such as dendritic cells, and then secrete cytokines that activate and differentiate other immune cells.
They also play a role in regulating the immune response to prevent excessive inflammation and tissue damage. Helper T cell dysfunction or depletion is associated with a number of autoimmune and infectious diseases.

in turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, what is the probability of an individual offspring having yellow feather?
50%
0
25%
100%
Answer:
50%
Explanation:
trust me because the heterozygous is so weird but I know this.
In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.
What will be produced in turkeys a dominant gene?In turkeys a dominant gene, R, produces the familiar bronze color; its recessive allele, r, results in red. Another dominant gene, H, results in normal feathers; its recessive allele, h, produces feathers without webbing, so that they resemble tufts of hairs.
Two bronze turkeys with normal feathers were mated, and their offspring consisted of eight bronze with normal feathers, three bronze with hairy feathers, two red with normal feathers, and one red with hairy feathers.
Since, this offspring received a recessive red, r, allele from each parent and a recessive hairy, h, allele from each parent, both parents must heterozygous for both characters: RrHh.
Therefore, In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.
