How do atmospheric conditions influence weather patterns?
Answers
Answer:
Air pressure is influenced by the differences between hotter and cooler pockets of air, or fronts.
Explanation:
When atmospheric pressure is low, air is pushed down toward the surface, meaning rain and moisture don't accumulate. This often also leads to high humidity near the surface of the Earth, where people experience weather. hope this helps you :)
A man with free earlobes and the ability to taste PTC marries a woman with free earlobes and no ability to taste PTC. They have four children. All of the children are tasters of PTC. Only one has attached earlobes. What are the genotypes of the parents?
Answers
Answer:
Father's genotype is T T, E e
Mother's genotype is t t, E e
Explanation:
Tasting PTC
Let the characters for tasting and not tasting PTC be T and t respectively.
Since all the children can taste PTC, it can be deduced that tasting PTC is a dominant trait.
The man will be homo-zygous dominant for tasting PTC while the woman is homo-zygous recessive for tasting PTC.
Genotype of man is T T and genotype of woman is t t
T T x t t = T t, , T t, T t; which is a 4:0 phenotype.
Earlobes:
Let the characters for Free and attached earlobes be E and e
Since both the man and woman have free earlobes and 3 out of 4 children have free earlobes, it can be deduced that free earlobes is dominant while attached earlobes is recessive.
The ratio of free to attached earlobes is 3:1
The man and the woman are both hetero-zygous dominant, E e for free earlobes, so that a cross between them will yield three hetero-zygous dominant for free earlobes and one homo-zygous recessive for attached earlobes.
E e x E e = E E, E e, E e, e e; which is a 3 : 1 phenotype.

A plant grows faster and fuller due to large amounts of fertilizer. If the plant cross-pollinates with another plant later, how will the use of fertilizer on the parent plant affect the plant’s offspring?
Answers
Answer:
The answer is "C" because nothing that your parents do, unless it directly affects/changes the gametes, will pass down to the offspring. Fertilizer is like food, how much your parents have eaten in their childhoods will have no effect on if you are under or over weight. (Unless their weight was by a genetic cause, that might have been passed on to you.)

Answer:
A cell is the smallest unit of a living organism
Explanation:
Just as an atom is described as the smallest unit if any substance, a cell is defined as the smallest, basic unit of any living organism.
This means that in order for something to be considered an organism, it has to contain, at least, a cell. Such organism with a single cell is referred to as a unicellular organism.
There are several organisms with more than one cell. Such organisms are said to be multicellular. Multicellular organisms often have their cells organized into tissues, organs, and or systems in order to function efficiently and maximally.
Cells can be of different types based on their level of complexity. The simple cells that do not have nucleus nor membrane-bound organelles are referred to as prokaryotic cells while the ones with complex structures with a nucleus and membrane-bound organelles are known as eukaryotic cells.

Answer:
natural selection leads to evolution
Explanation:
Natural selection leads to evolution. Therefore, the correct statement is option A.
What is natural selection?Evolution is a result of natural selection. Natural selection is an evolutionary mechanism that rewards people with specific features that help them live and procreate more successfully than those lacking such traits. New species evolve as a result of an increase in the frequency of these favorable features in the population throughout time.
Natural selection is a major force behind evolution in this way. However, other processes, such genetic drift, gene flow, and mutation, can also lead to evolution.
Natural selection and evolution are separate but closely connected ideas. It is one of the mechanisms that propels evolutionary change through time; as such, it is a mechanism of evolution. It acts on the genetic variation present in a population, favoring traits that increase an organism's reproductive success in a given environment.
Therefore, natural selection leads to evolution.

Which best describes what is occurring in this population of squirrels? Number of Squirrels Entering and Leaving a Population after 1 Year Cause of change Number of squirrels Died from predation 2 Born 4 Immigration 10 Left to find food 3 Died from disease 8 Left to find a mate 3
Answers
Answer:
Explanation:
The population of squirrel is decreasing and this can be traced to the environment not being favorable for their growth and development.
Looking at the data generated,
Died from predation =2
Born=4
Immigration=10
Left to find food =3
Died from disease=8
Left to find mate=3
If all the squirrel did not abandon their habitat and they all live there a total of 2+4+10+3+8+3= 30 squirrel would have been present, but given that only 4 were born and that others left for another place the population is reduced to 4 and 26 squirrel gone this has lead to a reduced population.

Which process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy? hypertonic transport active transport passive transport dynamic equilibrium
Answers
Answer:
Passive transport
Explanation:
Diffusion is a passive mechanism of transport. Until the concentration is the same throughout the space, a single substance has a tendency to travel from an area of high concentration to an area of low concentration. You are aware of how compounds diffuse through the air.
What are the passive transport dynamic equilibrium?Chemicals move passively from a location of higher concentration to a region of lower concentration through a process called diffusion.
We discussed three passive transport techniques: osmosis, assisted diffusion, and diffusion, all of which are crucial for cellular operations. Although the precise mechanics powering each of these transportation strategies vary, they are all non-energetic.
Therefore, Passive transport is a phenomenon that happens naturally and doesn't require the cell to use energy to move.

Select two specific components of the cell membrane and explain how each affects the permeability of the cell membrane. Meaning, what specific materials are regulated by the given component and how
Answers
Answer:
Phospholipid bilayer and carbohydrates.
Explanation:
Phospholipids form a double layer that protects the cell from the outside, in this layer the heads of the phospholipids, which are hydrophilic, are orientated towards the inside and the outside of the cell, and the tails of the two layers, which are hydrophobic, are in contact with each other. This bilayer allows the passage of certain substances due to its polarity, the elements that are too big, are ions, or that are hydrophilic have especial channels made of proteins that allow the passage of these kinds of elements
The other component that can affect the permeability is carbohydrates. These, when they attach to lipids and proteins, form a layer around the cell that allows the passage of certain substances, allows the recognition of the cells that are from the body, and the ones that are foreign so that there can be communication between cells.

The statement "A chicken learns that if it pecks on a button, a food pellet will be released into its cage" shows operant conditioning. So, option A is correct.
Operant conditioning, often known as instrumental conditioning, is a teaching strategy that use rewards and penalties to different behavior. Through operant training, actions that are rewarded are more likely to be repeated than actions that are penalised.
Pavlov's experiment with the dog is an example of classical conditioning, In classical conditioning, the stimulus that is repeatedly combined with the unconditioned stimulus until it finally elicits the same response is known as the conditioned stimulus.
Learning a skill by watching someone else perform it is an example of observational learning. Learning through observation of other people's behaviors is observational learning.
