When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it needs to react to an infection by -
Answer:
The correct answer is - increasing the rate of cellular respiration in the mitochondria.
Explanation:
During the infection, the body of mammals increases its temperature to kill the pathogens that normally die at high temperatures. To increase the body temperature our body promotes the rate of cellular respiration in the cells to produce more energy.
Cellular respiration is the process that helps in converting stored energy into a form of useable energy for the cell which is ATP. It takes place in the mitochondria of the cell which is called as the powerhouse of the cell and all the function related to energy or ATP is conducted by here.

Alice and her friends looked at a bunch of ladybugs. They noticed the ladybugs had different numbers of spots. They each had different ideas about why the numbers of spots were different.
This is what they said: Which person do you agree with the most?
A) Karen: I think they must all be different species of ladybugs.
B)Troy: I think each ladybug has the same number of spots as its parents.
C)Isaac: I think it depends on the age of the ladybugs. As they get older they add more spots.
D)Fred: I think it has to do with the sex of the ladybug. Males will add more spots to compete for the females.
E) Andrea: I think it depends on what each ladybug was born with.

Name two types of proteins that regulate the cell cycle. How do these proteins work?
Answer:
Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.
Explanation:
I hope this helps :)
The two types of proteins that regulate the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs). These two groups of proteins are responsible for the progress of the cell through various checkpoints.
What are Proteins?
Proteins are made up of hundreds or thousands of smaller units called Amino acids. They are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.
Cyclins regulate the cell cycle only when they are bound to Cdks and become fully active. The Cdk/cyclin complex must be phosphorylated, which further initiates other proteins to be phosphorylated that advances the cell cycle.
Retinoblastoma (Rb), is another group of tumor-suppressor proteins that regulates the cell cycle by monitoring the cell size.
Therefore, there are two types of proteins that regulate the process of the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs).

what is the definition of natrual asexul reprduction?
Answer:
In natural asexual reproduction, roots can give rise to new plants, or plants can propagate using budding or cutting. In grafting, part of a plant is attached to the root system of another plant; the two unite to form a new plant containing the roots of one and the stem and leaf structure of the other.

Answer:
The correct answer is - 0 m/s.
Explanation:
In this position-time graph or distance-time graph, there are three different part that shows three different velocities one in increasing as it moves from a lower position in relative to time and one is stationary and the third is decreasing.
'Straight lines' on a distance-time graph suggest that the movement of the object is constant. During 'Part B' of the journey the object travels 0m in 3s. It is stationary for 3 seconds so the velocity will be zero as well.

Read the passage. Then explain the ways humans have influenced the traits in corn plants and the impacts each biotechnology has had.
Passage
Many of the types of corn found in grocery stores were originally bred for their taste and productivity. But these varieties are often threatened by pests. This makes it harder for farmers to produce enough corn.
Scientists have used genetic engineering to make GMO corn plants that are resistant to pests. In one type of GMO plant, they added genes from bacteria that live in soil. The genes let the GMO plants produce a bacterial protein that kills certain insects.
Answer:
It decreases cost of production on the crop as well as increase production.
Explanation:
It is a very efficient method to save a corn plant from the attack of bacteria. This method is used in almost each and every plant in order to make it resistance against harmful pests and microorganism. By using this technology, the cost of production on the growing of crop decreases which gives more profit to the farmers as well increase the overall productivity of that corn crop.
Answer:
One of the ways we have influenced the traits in corn is through selective breeding. We now have taller plants, and bigger ears of corn, that taste better. Another way we have influenced the traits is by modifying them to be pest resistant.

a particle of oxygen has 8 protons and 8 electrons. is this an atom or an ion? what's the charge?
Answer: It is Atom and the charge would be postive.
Explanation: If the atom had 8 protons and 8 electrons (oxygen for example), knocking one of the electrons out, makes 8 protons and 7 electrons. The atom now has a net charge of +1 because the 7 electrons cancil the positive charges of 7 of the protons in the nucleus, but there is one remaining proton with a positive charge.Oxygen's 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge of the 8 protons. The positive charge of 1 proton exactly cancels the negative charge of 1 electron. Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!
Hope this helps :) Can u plz mark me branliest :)
A particle of oxygen has 8 protons and 8 electrons in an atom and the charge on it is zero.
What is an atom?It is the smallest particle of matter composed of electrons and a nucleus of protons and neutrons.
What is an ion?It is an atom with a positive or negative charge due to either loss or gain of electrons.
Every atom tends to have a noble gas configuration for stability and they either tend to lose, gain, or share electrons to achieve it.

You will measure and compare the heart rates of ten learners before and after
exercise. Choose ten learners in class who are willing to participate in this activity
They are the runners. Each of these runners must choose a classmate who will
measure his or her pulse rate.
Write down the question you are trying to answer in this investigation.
1.Write a hypothesis about the relationship between exercise and heart rate.
Answer:
Exercise is responsible for the increasing heart beat.
Explanation:
Exercise is responsible for the increasing heart beat because our body needs oxygen more faster during exercise. When we exercise our body needs quick energy and oxygen which can be provided by heart as well as the heart also removes carbondioxide which is produces during respiration process so the heart beat increases in order to provide energy and oxygen to the muscles.
Human blood is 90% water and 10% solute. What would happen if you gave
a patient an IV of pure water (0% solute)? The patient's cells will
remain unchanged.
swell or lyse.
shrivel.
Answer:
When a person receives fluids intravenously (through an IV bag, for example), a saline solution is sometime used. Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death.
Explanation:
The answer is B: It swells.
A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

how to do this question plz
Answer:
We are only given one leaf, but the leaves in layer D of the same species would not be identical. Some of them could have deeper indentations or fewer indentations. A wider leaf surface area lets a plant absorb more sunlight, so it would be an advantage if leaves have fewer indentations.
The plants with fewer indentations will reproduce more, passing on their genes for fewer indentations. This repeats for a long time, then plant leaves overall would only have very small indentations (like the leaf for layer B).
Explanation:
There are mutations and variations that make one organism different from another organism, even if they're the same species.
Natural selection is when the environment "chooses" the organisms that have an advantage in the environment to reproduce. Organisms that are selected to reproduce can pass on their genes to future generations.
The deep indentation leaves from layer D were basically "phased out".
If the length of the small intestine is ( 6 ) meters and the length of the large intestine ( 1.5 ) meters. what is the ratio of the large intestine to the small intestine
Answer:
1:4
Explanation:
According to the information provided in this question, the length of the small intestine is 6 meters and the length of the large intestine 1.5 meters. This means that the small intestine is longer than the large intestine.
To find the ratio of large intestine to the small intestine, we divide each length value by the smallest (1.5) i.e.
Large intestine = 1.5 ÷ 1.5 = 1
Small intestine = 6 ÷ 1.5 = 4
The ratio of large to small intestine according to this question is 1:4
