Claim: the mean resting pulse rate for men is less than 72
bpm.
Symbolic form would be: μ < 72
Step 1: null hypothesis : μ > = 7 2 b p m
Step 2: alternative hypothesis: μ < 7 2 b p m
Step 3: the test statistic is z = mean – μ / standard dev/sqrt (n) = -3/4 / 1.7639 = -1.92
Step 4: c v method: since z α = -1.645, the test static is z = -1.92 is less than the CV, we reject null hypothesis
P Value method: area is 0.0274, since the p value is <= α, reject null hypothesis.
Step 5: the sample data support the claim that the mean resting pulse rate for men is less than 72 bpm.
Bacteriophages are viruses that infect and duplicate within a bacterium. Temperate phages (such as lambda phage) can keep reproducing using both the lytic and the lysogenic cycle.
SO.... Bacteriophages
I believe is the answer that you are looking .
Let me know if its right or wrong!!
The best answer to choose would be — “Weak winds that blow for short periods of time with a short fetch.”
Few factors determinate size of surfing waves:
1The weaker the wind speed, the shorter the wave.
The shorter amount of time that the wind blows, the shorter the wave.
Concluding my statement, and in opposition to the answer, it is the stronger winds along with a long period of time those winds with a long fetch that will be able to make the biggest waves.
Answer:
The options are not given but they are gotten from another websites.
A. Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells.
B. Capillaries surrounding the brain have pores and are surrounded by membranes of astrocyte cells.
C. Capillaries surrounding the brain have no pores and are not surrounded by membranes of astrocyte cells.
D. Capillaries surrounding the brain have pores and are not surrounded by membranes of astrocyte cells.
The correct answer is option A.
Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells.
Explanation:
Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells because
Capillaries are tiny blood vessels in the circulatory system that connect aterioles to venules. They are the most abundant or they are much blood vessels. They can penetrate the tissues of the body which allow passage of food nutrients, oxygen in the body thereby allowing exchange of nutrients and oxygen between the body tissues and the blood.
Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells while capillaries in the periphery Capillaries surrounding the brain have pores and are not surrounded by membranes of astrocyte cells.
Answer: His genes contain a mutation that prevents red blood cells from proper functioning.
Explanation:
Hereditary anaemia is a type of disorder that are genetically transmitted to the offsprings by the parents . These type of anaemia are inherited from the parent including sickle cell anaemia.
The offsprings inherent Gene mutation that cause abnormalitiies. They inherit abnormal haemoglobin that can reduce the life span of red blood cells thereby affecting their proper functioning of carrying oxygen in the blood, leading to anaemia.
