What is the temperature at the interface
between the mantle and the outer core?
What can the reader conclude about homeostasis
Answer: Homeostasis helps animals maintain stable internal and external environments with the best conditions for it to operate. It is a dynamic process that requires constant monitoring of all systems in the body to detect changes, and mechanisms that react to those changes and restore stability.
A student found that 3 grams of ammonia gas formed 3 grams of solid ammonia when the
temperature was lowered enough. Why did the solid ammonia and the ammonia gas have the same
mass?
Answer:
The mass of a substance is constant according to the law of conservation of mass.
Explanation:
According to the law of conservation of mass, matter can never be created or destroyed in a chemical reaction, even though it may undergo change from one physical state to another.
This means that in an isolated or closed system, the mass of matter will always be the same irrespective of the type of change that matter undergoes. This is so because, the mass of a substance is a measure of the quantity of matter in that substance and is constant. The number of particles does not change during a change of state, only their spacing and arrangement. In solid ammonia, the particles are more compact and arranged, whereas in gaseous ammonia, they are more randomly spaced out.

Explanation:
Consider a duplex molecule of length 10 Mb that has only one origin of replication located exactly in the middle. If replication proceeds bidirectionally, assuming that the rate of DNA synthesis is 1500 nucleotide pairs per second, the time needed for replication of this molecule is _____ minutes.
Answer:
Approximately 28 minutes.
Explanation:
Given:
Length of a duplex molecule of DNA = 10 mb
= 10 * 10^6 bases
So, it means each DNA has = 5 * 10^6 base pair
rate of DNA synthesis = 1500 nucleotide pairs per sec.
location of replication = at the middle which is 5 * 10^6/2
= At 2.5 * 10^6
solution:
As we know replication of DNA is a bidirectional process so it will synthesize in both directions and the rate is given is 1500 nucleotide per sec so the time required to replicate 2.5 * 10^6 in both directions will be from the formula
time = distane/rate
= 2.5 * 10^6/1500
= 1666.66 seconds
or, 28 minutes aprrox (27.77)

photosynthesis is an example of...
an exothermic reaction
an endothermic reaction
a reaction that gives off heat

Answer:
Endothermic reaction
Explanation:
Photosynthesis is an endothermic reaction because sunlight is being absorbed during the reaction and the definition suggests that in a reaction if heat is being absorbed it is termed as an endothermic reaction.
In humans, to fold the tongue is a dominant trait (L), and the straight tongue is the recessive trait. What are the probabilities that the offspring can fold the tongue?
Explanation:
The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case: 1. dominant parent and recessive parent 2. heterozygous parents Answer: 1. dominant parent and recessive parent: dominant parents can be represented by LL and recessive parent is represented by II, so the gametes would be L, L and I, I. so, LL LI LI LI so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue. 2. heterozygous parents In this case, parents have LI genotype and gametes would be L and I for each parent so, L I L LL LI I LI I|so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue. 2. heterozygous parents In this case, parents have LI genotype and gametes would be L and I for each parent so, L I L LL LI I LI I| In this case, one is pure dominant and two heterozygous whereas only one is recessive the phenotype of offspring that cant fol the so, tongue would be: 75% = 3/4

How do convection currents work?
Answer:
Convection currents form because a heated fluid expands, becoming less dense. ... As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid. This cycle establishes a circular current that stops only when heat is evenly distributed throughout the fluid.
Explanation:
Convention currents work by forming a heated fluid expanding making it less dense. As the current rises, it pulls cooler fluid down to replace it.
In what type of cell does the cell wall take the place of the cell membrane ?
A. Plant cells
B fungi cells
C. Cell walls never take the place of a cell membrane
Answer:
Cell walls never take the place of a cell membrane
Explanation:
The cell wall has a texture that is tough, flexible, and occasionally hard and is found outside the cell membrane, hence option C is correct.
What is a cell wall?Plant cells' outside layer is called the cell wall. Only plants and some types of bacteria, fungi, and algae have cell walls.
Bacteria, algae, fungi, most plant cells, and certain archaea all have cell walls. A cell wall is a structure that surrounds the plasma membrane or cell membrane in cells that have them.
Cellulose or chitin are the main components of the cell wall, which is a stiff, semi-permeable structure.
Glucans, chitin, and glycoproteins make up the majority of the cell wall, which is a distinctive structure of the fungus.
Therefore, cell walls never take the place of a cell membrane.
