B letter in the diagram below represents the location where deoxygenated blood returns to the heart from the body.
What is deoxygenated blood?"Deoxygenated blood refers to the blood that has a low oxygen saturation relative to blood leaving the lungs."
What is the function of deoxygenated blood?"The deoxygenated blood returns from the body to the right atrium and from there enters the right ventricle that pumps it to the lungs through the main pulmonary artery. In the lungs, the blood refills its oxygen supply and gets rid of carbon dioxide."
What are the steps of the circulatory system?The steps involved in blood flows through the heart in the following order:
The blood first enters the right atrium.The blood then flows through the tricuspid valve into the right ventricle.When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.The pulmonary artery carries blood to the lungs where it “picks up” oxygen.To know more about deoxygenated blood here https://brainly.com/question/1216980

which direction do new york state weather systems usually approach from
Answer:
west to east
Explanation:
The weather system of New York moves in the west to east direction. It is driven by the jet stream which moves from west to east.
The jet stream is nothing but the normal trade winds that blows in and around the equator and move from west to east. While very strong wind forces start blowing from east to west due to the tropical trade winds
Would would be the possible gamete combinations?
Answer:
1/4 WR; 1/4 wr; 1/4 wR; 1/4 Wr
Explanation:
The principle of independent assortment indicates how different genes independently separate from one another when gametic (reproductive) cells develop. When a cell divides by meiosis, homologous chromosomes are randomly distributed to daughter cells, thereby different chromosomes segregate independently of each other. In consequence, each gamete has a unique combination of chromosomes. In this case, the two genes are on different homologous chromosomes, thereby gene variants (alleles) will be randomly distributed to daughter cells during meiosis (anaphase I) and thus the expected proportion of gamete genotypes will be 1/4 WR, 1/4 wr, 1/4 wR, 1/4 Wr.
give possible reasons for the poor performance of the monopolies
Explanation:
goods can be restricted to keep prices high. This leads to underprovision, or scarcity
The main reason of the poor performance of the monopolies is it is more expensive than in competitive markets Monopolies face inelastic demand and can raise prices, leaving consumers with no choice.
What is monopoly?A monopoly occurs when there is a solitary vendor on the market. The monopoly case is considered the polar opposite of perfect competition in conventional economic analysis.
The major issue facing the monopolist is, by definition, the industry demand curve, which is slightly negative.
The drawbacks are:
Expensive in comparison to competitive markets Monopolies can raise prices when demand is inelastic, leaving consumers with no choice.A reduction in consumer surplus.Monopolies have a lower likelihood of being efficient.Potential scale diseconomiesThus, these are some of the for poor performance of the monopolies.

It is well known that sugars glucose and fructose are the primary fermentable substrates. However, malic acid can also be fermented but to lactic acid rather than ethanol. This is especially important in red wine, why?
Answer:
The correct answer is - due to the different bacteria that produce a different enzyme that is involved in the fermentation of malic acid.
Explanation:
In red wine production, malic acid in present in grapes converted to a softer lactic acid. This process is known as malolactic fermentation. It takes place due to the presence of different types of bacterias such as bacteria of the lactic acid family.
These bacterias produce enzymes which is used to convert the malic acid to lactic acid such a process can occur naturally also.

Which kind of evidence is used by scientists to understand the intermediate states between an ancestral form and that of its
descendants?
A) causation
B) correlation
C) natural selection
D) transitional fossils
The intermediate states between an ancestral form and that of its
descendants are transitional fossils.
What is a transitional fossil?
Transitional fossils are remains of an organism that came in between a known version of a species and the current species.
Transitional fossils would be proof of evolution because they would show medium forms of a species and they altered and accumulated adaptations at a slow pace.
Thus, option "D" transitional fossils are correct.

Answer:
- Contains myelinated axons: White matter
- Posterior column: White matter
- Located to the periphery of the spinal cord: White matter
- Gracile fasciculus: White matter
- Anterior spinocerebellar tract: White matter
- Medial vestibulospinal tract: White matter
- Marked by low myelination: Gray matter
- Functions to integrate arriving electrical signals: Gray matter
- Contains somas, synapses, and dendrites: Gray matter
- Tectospinal tract: White matter
- Functions to transmit electrical signals rapidly over long distances: White matter
- Lateral horn: Gray matter
- Ventral horn: Gray matter
Explanation:
Both the brain and the spinal cord contain white matter and gray matter. White matter is the tissue responsible for information transmission (i.e., axons); whereas gray matter is mostly involved in information processing (i.e., neuron bodies). White matter is composed of myelinated axons which extend out from the neuron bodies and glial cells, and this tissue connects different areas of the cerebral cortex (i.e., the outer layer of the brain). Moreover, gray matter is composed of neuronal cell bodies or 'soma' that contain the neuron’s nucleus and unmyelinated axons. Gray matter also has glial cells and capillary blood vessels; whereas white matter also has oligodendrocytes that produce myelin and astrocytes. The color of the white matter is caused by the myelin that surrounds the axons; while the color of the gray matter is due to the capillary blood vessels and neuronal cell bodies. In the cerebrum and cerebellum, white matter is observed in deep areas coated by gray matter; whereas, in the spinal cord, the white matter surrounds the central gray matter. White matter is involved in normal motor and sensory function, this tissue is responsible for learning and coordinating communication between different brain regions. Moreover, grey matter is involved in muscle control and sensory function (e.g., hearing, vision, memory, emotions, speech, decision making, etc).

The enzyme tryptophan synthetase is produced sizes, large and small. Some mutants with no enz tivity produced exactly the same size enzymes as the wild type. Other mutants with no activity produced its the large enzyme; still others, just the small enzyme.
a. Explain the different types of mutants at the level of protein structure.
b. Why do you think there were no mutants that produced no enzyme?
Answer:
Due to changes occur in the protein structure.
Explanation:
The different types of mutants produced at the level of protein structure because mutation changes the protein structure of organism which leads to different types of mutant organisms. There were no mutants that produced no enzyme because enzymes are the most important part of the body in order to help the organism in their survival. These enzymes speed up the process of chemical reaction.

Living organisms are commonly divided into six kingdoms: archaea, bacteria, fungi, protists,
plants, and animals. What’s the biggest problem with classifying organisms in this way?
they may be in the same category but they don't have the same biological makeup
The biggest problem in classifying organisms this way is that the way is not well-defined and diverse and if any organism doesn't fall into another kingdom that is added to these kingdoms.
What is classification?Organisms are classified into groups and classes on the basis of their characters and structure. It helps in identifying and understanding the diversity of living organisms.
The six kingdom classification is based on similar characteristics like cell type, and food. Before this, scientists divide the organism into plants and animals.
Thus, The major issue with this system of classifying creatures is that it is not well-defined and diverse, and if an organism does not fit into one of the existing kingdoms, it is added to those already there.
