Given that there are 250 seats in the cinema and they are 170 people sitting on the seats provided, in order to get the percentage we will first arrange the given details.
250 seats
170 seats filled
X = percentage
Take 170 / 250
So it will be 170 ● 100 = 17,000
Next, 17,000 250 = 68
So we will have 170 is the 68% of 250. Therefore, 68% of the seats in cinema are filled.
A) blood vessel diameter
B) receptors in the aorta
C) vasomotor center
D) blood pressure
Answer:
Answer is D. Blood pressure.
Explanation:
Blood pressure is the pressure of the blood within the arteries, produced by the contraction of the heart muscle.
Answer:
In an unfortunate accident, a young man is struck in the leg by a bullet that tears through an artery just above his right knee. The subsequent blood loss leads to a rapid drop in blood pressure. Receptors in the aorta monitor blood pressure and send signals to the vasomotor center of the brain. In this case, the vasomotor center will increase its stimulation of smooth muscle in the blood vessels, which will cause them to constrict. This constriction leads to an increase in blood pressure.
What represents the effector in this feedback system? receptors in the aorta
Explanation:
In a changing environment, the species which will have the best chances for survival are the one with the biggest genetic variation. Thus, the correct option is C.
Genetic variation is the difference in DNA present among different individuals or the differences between the populations. The multiple sources of genetic variation include mutations and genetic recombination in species. Mutations are the ultimate source of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Variation allows some individuals within a population to adapt better to the changing environmental conditions. Because, the natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation in a population.
Therefore, the correct option is C.

Answer:
one with the largest poplation because they can cook,protect, and get supplies .
Explanation:
Answer:
Your three blood cell types have different sizes, shapes, and functions. Yet they all started out alike. Within each cell of your body there are chromosomes which give the instructions for cell processes. These instructions include the differentiation of your blood cells
Explanation:
In the chromosomes the DNA is packed, from its sequence and from other control mechanisms the genetic expression is regulated and instructions are given to generate one or another type of cell. This happens because there is a differential expression of the different genes according to the cell type.
Answer:
Drinking water helps maintain your body
Answer:
the balance of body fluids.
Explanation:
The ability to have these body fluids is very important as they help digestion, absorption, circulation, creation of saliva, transportation of nutrients, and maintenance of body temperature. Drinking water also helps your memory, health, and recovery.

Our bones serve as storage for crucial minerals like calcium and phosphorus, which are significant for various bodily functions, confirming the trueness of the statement.
The statement, 'some important minerals are stored in the bones', is true. The human body uses bones as a reserve for minerals such as calcium and phosphorus. These minerals contribute to the strength of our bones, and are also essential for numerous functional roles in the body. For example, calcium is necessary for muscle contraction and neuron function. Phosphorus, on the other hand, forms part of DNA and cell membranes, and also helps regulate the body's pH balance.
