Does grain size determine the porosity of a sediment type?
Answer:
Yes
Explanation:
In sediments or sedimentary rocks the porosity depends on grain size, the shapes of the grains, and the degree of sorting, and the degree of cementation. Well-rounded coarse-grained sediments usually have higher porosity than fine-grained sediments, because the grains do not fit together well

Answer:
The process of nerve impulse transmission by means of an action potential involves the processes of depolarization, repolarization, hyperpolarization and restoration of resting memebrane potential.
Explanation:
In order for a neuron to receive and transmit a message it must be in a polarized state. While in this rest state there are more sodium ions outside the cell membrane while potassium is prevalent inside the cell. This causes the neuron to maintain a neutral charge. Once the action potential arrives at its dendrites, a nerve cell will shuttle the message down its own axon and to the next neuron via its axon terminal. This impulse will cause the cell to become depolarized and will effectively change the charge of the neuron to a poositive charge. After sodium rushes into the cell, the potassium will rush out in order to restore its resting memebrane potential. Once the impulse reaches the axon terminal, it is used to open voltage- gated calcium channels releasing calcium ions that stimulates a neurotransmitter to continue the message to the next neuron. The neuron then undergoes a repolarisation when all ions are repositioned with help of the voltage-gated ion channels.

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

What is molting????????
A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.
In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is the manner in which an animal routinely casts off a part of its body (often, but not always, an outer layer or covering), either at specific times of the year, or at specific points in its life cycle.
Moulting can involve shedding the epidermis (skin), pelage (hair, feathers, fur, wool), or other external layer. In some groups, other body parts may be shed, for example, wings in some insects or the entire exoskeleton in arthropods.

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. ( Ya'll i need a hypothesis )
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.

what happens to macromolecules from food during digestion?
what atoms makeup sugar molecules, amino acids, and fatty acids?
what do you notice about the atoms that make up these molecules?
how are these atoms used to make new molecules? what types of molecules are made?
where does the energy come from to produce these new molecules?
Answer:
In chemical digestion, enzymes break down food into the small molecules the body can use. It is important to break down macromolecules into smaller fragments that are of suitable size for absorption across cell membranes.
Amino acids are the monomers that makes up protein
If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.
BONDING. When atoms join together to form molecules, they are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms. ... Different atoms use these electrons to form one of three different types of bond: ionic bonds, covalent bonds, or metallic bonds.
Proteins. ...
Lipids. ...
Carbohydrates. ...
Nucleic Acids.
Respiration, which consists of three phases, occurs in the mitochondria, the cell's “powerhouses.” This metabolic pathway traps the maximum amount of stored chemical energy within a molecule of glucose, generating a total of 30 molecules of ATP in conjunction with glycolysis.
