Answer:
D. Layer B
Explanation:
The correct answer is Layer B.
The law of superposition actually states that the sedimentary rock unit is at the bottom while the the youngest rock is at the top. The principle of cross-cutting relationships states in layers of rocks, a fault or intrusion that cuts through rock layers is younger than the rocks that it cuts through.
Layer B was actually formed after Layer C. This makes Layer B younger than Layer C and closest in age to Layer C. The intrusion, Layer D is the youngest of all.

due to the salmons body and biology the salinity doesnt matter because they can change whats around them using the salt from inside their body
Explanation:
they both utilize and alter behavior
The populations of juvenile salmon respond to changes in salinity as they migrate the juvenile salmon utilize special structures to alter their behavior. Therefore, option C is correct.
What is salinity ?The amount of dissolved salt in a body of water is known as salinity. It makes a significant contribution to conductivity and influences many aspects of the chemistry of natural waters as well as the biological activities that take place there.
In soils and seas, primary salinity is a natural occurrence. Salt lakes, salt pans, salt marshes, and salt flats are a few examples of naturally occurring salty landscapes. Salting caused by human activity, typically land development and agriculture, is known as secondary salinity.
Salinity is the buildup of salt to a degree that harms the built environment and the ecosystem in general. While there are many areas of the Australian terrain that are naturally salty, human activity has the potential to raise salt levels. Water and salinity go hand in hand.
Thus, option C is correct.

Introspection is one of the many sleeping disorders experienced
by people with sleep apnea.
Select one:
True
False
Answer:
The statement is false.
Explanation:
Sleep apnea is a respiratory disease characterized by the fact that people who suffer from it habitually snore, have repeated stops of breathing (apneas) and drowsiness during the day. As a consequence, patients who suffer from it cannot rest well during the hours of sleep.The obstruction of breathing causes a decrease in oxygen levels in the body, the persistence of this lack of oxygen could cause pulmonary hypertension and a future right-sided heart failure or myocarditis. Introspection, on the other hand, is the immediate reflective capacity of the human mind to know its own states; it is not associated with sleep apnea.

How does the DNA change during meiosis?
Answer:
Scotland
Law is a surname, of English, Scottish, Cantonese, or Chinese origin. In Scotland, the surname means dweller at the low; as in a hill. Another origin of the surname is a contraction of Lawrence, or Lawson.
Explanation:
Answer:When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.

Answer:
Membrane proteins can allow hydrophilic molecules to pass through the cell membrane.
Explanation:
Answer:
Explanation:
Membrane proteins are common proteins that are part of, or interact with, biological membranes. Membrane proteins fall into several broad categories depending on their location. Integral membrane proteins are a permanent part of a cell membrane and can either penetrate the membrane (transmembrane) or associate with one or the other side of a membrane (integral monotopic). Peripheral membrane proteins are transiently associated with the cell membrane.

Which of the following statements about cell respiration is true?
A In the electron transport chain, Oz is converted to CO2.
B Glycolysis splits sugar to produce pyruvate and FADH2-
C Electrons leave the electron transport chain in a molecule of water (H20).
D
Both B and C are correct.
The statement which is true about cell respiration is; Choice B: Glycolysis splits sugar to produce pyruvate and FADH2-
Definition of terms:
Cellular respiration is a process used by all living organisms to convert glucose into energy.
Cellular respiration is a collection of three unique metabolic pathways: glycolysis, pyruvate oxidation, the citric acid cycle, and the electron transport chain.
Glycolysis; This pathway is anaerobic and takes place in the cytoplasm of the cell. This pathway breaks down 1 glucose molecule and produces 2 pyruvate molecule. A process which releases FADH2- in the process.Pyruvate Oxidation: In eukaryotic cells, the mitochondria is the site of pyruvate oxidation. The release of CO2 is a characteristic of this step.The Electron transport chain: The electron transport chain is the final component of aerobic respiration and is the only portion of glucose metabolism that uses atmospheric oxygen.Electrons are rapidly transferred from one component to the next to the endpoint of the chain, where the electrons reduce molecular oxygen, O2 producing water in the process.

how many chromosomes are there in human ovum
Answer:
23 chromosomes
Unlike all the other cells in a human body which are diploid, human sex cells are haploid. That means that both sperm cells and ova are haploid; containing only 23 chromosomes.
Explanation:
have a good day!
(─‿─)
The chromosomes in egg and sperm cells have just 23 chromosomes each.
What is gamete?Male gametes are termed sperm, while female gametes are called "ova." Gametes are an organism's reproductive cells, also referred to as "gender cells." Since gametes are haploid cells, each chromosome is present in one copy per cell.
Unfertilized reproductive cells are called gametes. A zygote is an egg that has been fertilized. Gametes are always haploid cells since they are a byproduct of meiosis.
Zygote is a diploid structure because it results from the fusing of a male and female haploid gamete.
Similar to a sperm, an egg has 23 chromosomes total, which is half the number found in a normal cell.
The resultant embryo will therefore have the typical 46 chromosomes in total after an egg and sperm join during fertilization.
Thus, there are 23 chromosomes in human ovum.

Solar power is the power of the future and is an essential nonrenewable source of energy for man. Solar power is driven by the incoming solar energy in the form of solar rays. Solar power is eco-friendly and doe not cause any harm can be sued in the summer season and has ample scope for greenhouse gases. As per the statement, the solar power should be used as the main energy source in U.S can be contradicted by saying it contributes to global warming.What is soil structure?
Answer:
Soil structure is defined by the way individual particles of sand, silt, and clay are assembled. Single particles when assembled appear as larger particles. These are called aggregates.
Explanation:
Aggregation of soil particles can occur in different patterns, resulting in different soil structures. The circulation of water in the soil varies greatly according to structure, Therefore, it is important for you to know about the structure of the soil where you plan to build a fish-farm. Although you may not be able to assemble all this information yourself, the specialized technicians from the soil testing laboratory will be able to provide it after examining your undisturbed soil samples. They will be able to tell you if your soil has bad structure or good structure (pores/capillary canals, network, etc.). They will also be able to tell you about the degree of water circulation or permeability.
