Identify the types of breezes and the areas of high and low pressure that cause them.
Answer:
There are 4 types of breezes: land breeze, sea breeze, mountain breeze and valley breeze.
The breeze will originate from an area of high pressure and travel towards/blow in the direction of the area at a lower pressure.
In each case, the name of the breeze indicates where the breeze is blowing from. For instance, the land breeze will blow from the land (at high pressure) to the sea (at lower pressure). A mountain breeze will blow from mountain (at high pressure) towards the valley (at low pressure).

contrast homozygous and heterozygous genotypes? Dont copy from the internet please
Answer:
I got you
Explanation:
homozygous is when the letters are AA or aa NOT Aa
heterozygous is when it is Aa
The homozygous can only pass down A or a, not both. If the parent was AA, the probability of their offspring would be more likely to have a dom. phenotype is more likely. If it was aa, they are more likel to create heterozygous and recessive offspring.
The heterozygous coding is able to pass on both the recessive and dom. traits. So the offspring would be more dependent on the other parent, but most likely will have more dom. offspring.

The part the nervous system that contains the cerebrum and cerebellum is the brain. The brain is an organ in the body that controls different other activities in the body. Almost everything in the body is controlled by the brain. The three main parts of the brain is; cerebrum, cerebellum, brainstem. The cerebrum controls speech and emotion, the cerebellum controls movement and the brainstem controls sneezing, coughing.
Spinal cord is a part of the nervous system transports information between the brain and other parts of the body. The spinal cord is a tubular and thin structure composed of nervous tissue. The spinal cord functions are to the transmission of neural signals among the brain and other parts of the body. Spinal Cord is necessary because the brain communicates with the body through it.
Thus, the brain sends information by the spinal cord to the peripheral nerves everywhere to the body that serves to regulate the muscles and inner organs.

What are the functions of cell?Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life.

Answer:
guy above is correct
Explanation:
A box has 400 J of gravitational potential energy and weighs 100 N how many meters above the ground is it
Answer:
4 meters
Explanation:
The formula for gravitational potential energy is mgh, where m is the mass of the object in kilograms, g is the gravity, and h is the height in meters. You can use this to set up the following equation:
400=100 * h
h=4 meters
Hope this helps!
The gravitational potential energy is 400J of the box whose weight is 100N. Therefore, the height for which box is above the ground is 4 meters.
What is Gravitational Potential energy?
Gravitational potential energy is the energy which an object possesses because of its position above the ground level in a gravitational field such as the gravitational field of the Earth. The gravitational acceleration of the Earth can be assumed to be constant at about 9.8 m/s².
The gravitational potential energy can be calculated by the formula:
G.P.E = m × g × h
where, G.P.E = Gravitational Potential Energy,
m = mass of an object,
g = acceleration due to gravity = 9.8 m/s²,
h = height which the box attains
G.P.E = w × h (Since, w = m × g)
h = G.P.E. / w
h = 400J / 100N
h = 4 meters
Therefore, the height of the object is 4 meters.

Answer:
digestive respirtory
Explanation:
The body can be invaded by pathogens , which are harmful microorganisms that cause infection diseases. The body then initiates a(n) inflammatory response, which may involve redness, swelling, and fever.
Answer:The term "disease" refers to conditions that impair normal tissue function. For example, cystic fibrosis, atherosclerosis, and measles are all considered diseases. However, there are fundamentally different causes for each of these diseases. Cystic fibrosis (CF) is due to a specific genotype that results in impaired transport of chloride ions across cell membranes, leading to the production of abnormally thick mucus. Thus, CF is most accurately called a genetic or metabolic disease. Atherosclerosis, which can lead to heart attacks and strokes, may be considered a disease of aging, because it typically becomes a problem later in life after plaques of cholesterol have built up and partially blocked arteries. In contrast, measles is an infectious disease because it occurs when an individual contracts an outside agent, the measles virus. An infectious disease is a disease that is caused by the invasion of a host by agents whose activities harm the host's tissues (that is, they cause disease) and can be transmitted to other individuals (that is, they are infectious).
