In subduction what plate would be on top and what plate would be on the bottom?
Answers
Answer:
oceanic plate would slide under the continental plate
Explanation:
continental is on top, oceanic on bottom
Answer:
When an oceanic lithosphere meets a continental lithosphere in a subduction zone, the oceanic plate always goes under the continental plate. This is the rule because the rock making up an oceanic lithosphere is denser than in a continental lithosphere.२०२० मे
Vascular resistance is due to friction between blood and the walls of the blood vessel. Which of the following causes low vascular resistance?
obesity
dehydration
high blood pressure
cholesterol levels within normal range
Answers
Answer:
Cholesterol levels within normal range
Explanation:
Vascular resistance is due to friction between the blood and the walls of the blood vessel, and cholesterol levels within the normal range can cause low vascular resistance, which is the last option.
What is vascular resistance?Vascular resistance is the resistance to blood flow in the blood vessels, which is determined by the diameter of the blood vessels, blood viscosity, and the length of the blood vessels, so when blood flows through the blood vessels, it experiences frictional forces due to the interaction between the blood and the walls of the blood vessels, obesity, dehydration, and high blood pressure can all contribute to increased vascular resistance.
Hence, the correct answer is that cholesterol levels within the normal range can cause low vascular resistance, which is the last option.

The complete question is as follows:
Hypothesis Cas More Information: Here is a summary of the data, Mass of DNA Cat Res per Coll Mother Father Calix 1520 fg 1495 fg 1535 fg . The mass of an X chromosome is 40 fg. • Point mutations do not change the mass of DNA. • In chromosomal rearrangement, some daughter cells gain parts of chromosomes and some lose parts of chromosomes. • In nondisjunction, daughter cells gain a whole entire chromosome. Obe Exp Нур 는 Exp Point Mutation in Melosis Chromosomal Rearrangement Nondisjunction Choose the mutation that you think has caused Calix's calico fur coloring. Form a hypothesis to explain your reasoning. You will be able to revise your hypothesis as you collect more data.
Answer:
The correct answer is - non-disjunction.
Explanation:
Calix's calico has an X chromosome gene that determines the color of fur. One allele forms orange fur and the other give rise to black. In heterozygous give rise to orange patches on black.
Mother has autosome and 2-X chromosomes.
Mass of 2 X chromosomes will be
= 40*2
= 80fg
So mass of autosomes = 1520-80
= 1440fg
Mass of sex chromosomes in father is = 1495-1440
= 55fg
So the mass of Y=55-40
= 15fg
It is clear that the mass of DNA of Calix is exactly 15 more than DNA of the mother. So we can say that Calix has an entire Y chromosome in extra.
So the answer is non-disjunction.
The right option is - non-disjunction.
Information regarding Calix’s calico:It comprises of X chromosome gene that measured the fur color. In the case of heterozygous, it provides the increment with respect to orange that patches on black.
Since Mother has autosome and 2-X chromosomes.
So,
Mass of 2 X chromosomes should be
= 40*2
= 80fg
Now
The mass of autosomes should be
= 1520 - 80
= 1440fg
Now
Mass of s-ex chromosomes in father should be
= 1495-1440
= 55fg
Now finally the mass of Y is
= 55 - 40
= 15fg
Based on the above calculation, the mass of DNA of Calix should be 15 i.e. more than the DNA of the mother.

Complete the table below to show the difference between active and passive transport. Put a “X” in boxes that satisfy the statement.
Answers
Answer:
Active transport:
requires energymolecules move from low to high concentration sidesNa+ and K+ move by active transportSimple diffusion:
molecules move from high to low concentration sidesmolecules pass between lipids small non-polar and polar moleculesFacilitated diffusion:
molecules move from high to low concentration sidesinvolves channel proteinsmove large moleculesExplanation:
Simple Diffusion is the pathway of only small molecules that freely move through the membrane by momentary openings produced by the lipids' movements. Diffusion is a slow process that requires short distances and pronounced concentration gradients to be efficient. An example of diffusion is osmosis by which water is the transported molecule. Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient. Glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.Simple diffusion and facilitated diffusion are both passive transport processes because they only depend on electrochemical gradients, so they do not need any energy to occur.
Active transport is the transport of molecules that move against the electrochemical gradient, so it does need energy to happen. Molecules move from the lower concentration side to the higher concentration side of the membrane. Carrier proteins are in charge of active transport. The needed energy might proceed from the ATP molecules or the membrane's electric potential. An example of molecules moved by active transport are the Na and K.In Active transport, molecules or ions move against the concentration gradient by using energy from ATP.
What is Membrane transport?The transfer of molecules across the plasma membrane into or out of the cell.
There are two types of membrane transport,
1. Passive transport:
When molecules move along the gradient. It can be of two types,
Simple diffusion (via phospholipids)Facilitated diffusion (via channel protein)2. Active transport:
When molecules move against the concentration gradient, they require energy. Energy is given by ATP.
Therefore, in Active transport, molecules or ions move against the concentration gradient by using energy from ATP.
