Answer:
so the body works to maintain homeostasis in response to internal or external conditions
Explanation:
Homeostasis is the process of maintaining a stable internal conditions, Homeostasis keeps internal conditions just right for cell function.
Its like if your hot your body with sweat to cool you down
OR
when your cold you shiver which contracts the things inside of your body so your body contains more heat rather than releasing it
An example of Homeostasis in response to internal conditions is:
when your body produces too much glucose, your body releases insulin to bring the level of glucose down
and when there isnt enough glucose your body releases glucagon to bring up the level of glucose to stable your blood sugar
Homeostasis has been the bodily process that is involved in maintaining the environment of the body. The body works to maintain homeostasis in response to internal and external changes.
What is homeostasis?Homeostasis has been defined as the steady internal environment for the maintenance of physiological processes. This involves the optimization of the variables and carious functions so that equilibrium can be achieved.
The factors involved in homeostasis are pH levels, temperature, glucose, etc. It has been the response of the cell towards the external environment so as to maintain balance. The homeostatic range is important for the proper functioning of the body.
The changes in the internal and external environment affect homeostasis as an increase in temperature in summer leads to sweating and a decrease in temperature in winter leads to shivering. It uses the feedback mechanism to maintain equilibrium.
Therefore, the process of homeostasis is in accordance with internal and external changes.

A yellow cat is crossed with a black cat. You know that the black and yellow fur color traits are carried on the X chromosome and only one X chromosome is expressed in a cell. You observe that half the offspring are calico (patches of black and yellow) and half are black. Your friend Tien tells you that the black cat was the mother, the yellow cat was the father, and all the calico kittens are females. Is he correct? Write out all the possible crosses to test his answer.
Answer:
Tien is correct with his answer that all the calico kittens are females.
The reason and the possible crosses to test the answer are given below
Explanation:
First of all, the coat color in cats is hugely decided by the sex-linked X chromosome in the female. This X chromosome found in cats makes cats exhibit codominant traits. The calico cat is a blend of black and yellow patches. To be considered calico, a cat must carry an allele for the black color and an allele for the yellow color.
The male is no heterozygotes and since the Y- chromosome in the male doesn't affect the result of the coat color in the offspring, there has to be a rare genetic disorder that will result in a calico kitten that is male.
The possible crosses to test his answer:
Cross 1:
If the black cat was the mother her genotype would be: Xb Xb
If the yellow cat was the father his genotype would be: Xy Y
The possible offspring from the cross would result in:
XbXy XbY XbY XbXy ( where XbXy are calico females and XbY are black males)
Cross 2:
If the yellow cat was the mother her genotype would be: Xy Xy
If the black cat was the father his genotype would be: Xb Y
The possible offspring from the cross would result in:
XyXb XyY XyXb XyY (where XbXy are calico females and XyY are the yellow males)

The Life Cycles of Stars: How Supernovae Are Formed
It is very poetic to say that we are made from the dust of the stars. Amazingly, it's also true! Much of our bodies, and our planet, are made of elements that were created in the explosions of massive stars. Let's examine exactly how this can be.
Life Cycles of Stars
A star's life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. Over time, the hydrogen gas in the nebula is pulled together by gravity and it begins to spin. As the gas spins faster, it heats up and becomes as a protostar. Eventually the temperature reaches 15,000,000 degrees and nuclear fusion occurs in the cloud's core. The cloud begins to glow brightly, contracts a little, and becomes stable. It is now a main sequence star and will remain in this stage, shining for millions to billions of years to come. This is the stage our Sun is at right now.
As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts. The outer shell of the star, which is still mostly hydrogen, starts to expand. As it expands, it cools and glows red. The star has now reached the red giant phase. It is red because it is cooler than it was in the main sequence star stage and it is a giant because the outer shell has expanded outward. In the core of the red giant, helium fuses into carbon. All stars evolve the same way up to the red giant phase. The amount of mass a star has determines which of the following life cycle paths it will take from there.
diagram of the life cycles of low and high-mass stars
The life cycle of a low mass star (left oval) and a high mass star (right oval).
The illustration above compares the different evolutionary paths low-mass stars (like our Sun) and high-mass stars take after the red giant phase. For low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf.
On the right of the illustration is the life cycle of a massive star (10 times or more the size of our Sun). Like low-mass stars, high-mass stars are born in nebulae and evolve and live in the Main Sequence. However, their life cycles start to differ after the red giant phase. A massive star will undergo a supernova explosion. If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star. The core of a massive star that has more than roughly 3 times the mass of our Sun after the explosion will do something quite different. The force of gravity overcomes the nuclear forces which keep protons and neutrons from combining. The core is thus swallowed by its own gravity. It has now become a black hole which readily attracts any matter and energy that comes near it. What happens between the red giant phase and the supernova explosion is described below.
FRUCTOSE AND GLUCOSE: One is the source of most of our energy that our bodies use. The other has exactly the same chemical formula, but its atoms are put together in a different way …….. and that makes it, in some combinations, very bad for the body. Why?
Answer:
Fructose is the sugar in organic fruits that gives energy to cells and Glucose is the other one.
Explanation:
Glucose is the bad one for you body because it is unnatural sugar. Which means it sends energy to your body but the energy is used up very quickly. It is like cafience but it's baby.

Which of the following best describes the process by which gas from the atmosphere is obtained by plants and used to build lipids?
A
Gas is fixed by plants as part of the sulfur cycle.
B
Gas is fixed by plants as part of the nitrogen cycle.
C
Gas is directly obtained by plants as part of the carbon cycle.
D
Gas is directly obtained by plants as part of the magnesium cycle
Answer:C
Explanation:They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.
The process by which gas from the atmosphere is obtained by plants and used to build lipids is best described by option C (Gas is directly obtained by plants as part of the carbon cycle).
The carbon cycle is the process that brings about the circulation of carbon compounds in nature.
Carbon exists in nature as the gas carbon dioxide which makes up 0.03% of air.
The plants uses carbon dioxide in a process called photosynthesis to manufacture their own food (glucose).
Excess glucose produced by plants, are converted to substances such as starch and lipids, which are then stored in various parts of plant.
