Arturiano [62]3 years ago
3 0
Darwin and the Grants philosophy on WHY birds beaks are different shapes on different islands. They both agree this can be attributed to the source of food. However, Darwin posed that this occurred over a very very long time and the Grants showed (with data that they collected) that this can happen in a much shorter time
period.

what is difference between the name of an object versus the chemical formula?please answer my question I'm trying that from thre
Step2247 [10]

Answer:

Assuming you mean in a compound of elements: A name is just what you call it, and the chemical formula is what elements it is made of.

Explanation:

Take sodium chloride (Salt) for example. It's name is sodium chloride, but its chemical formula is NaCl. Na= Sodium, and Cl = Chlorine. So one sodium ion and one Chlorine ion create NaCl. Na+Cl=NaCl. And the name for the product of the formula is Sodium Chloride.

Another example is H2O (Water). H=Hydrogen and O=Oxygen. There are 2 hydrogens and one oxygen in H2O. H+H+O=H2O. The name for the formula is water.

Pani-rosa [81]
The horse will give 32 chromosomes and donkey will give 31 chromosomes to the offspring.
The offspring has 63 in total.
 It is odd so it can not produce normal germ cell. So it is sterile.

The mean resting pulse rate for men is 72 beats per minute. a simple random sample of men who regularly work out at mitch's gym
tamaranim1 [39]

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.

The cell bodies of sensory neurons that are in clusters of neurons outside the spinal cord are called ____.
Nonamiya [84]

Answer:

The cell bodies of sensory neurons that are in clusters of neurons outside the spinal cord are called  ____

The answer is "dorsal root ganglia"

Explanation:

Explanations of some terms

Sensory neurons:

Sensory neurons, also known as afferent neurons, have cell bodies that are located in the dorsal ganglia (also known as  spinal ganglia) of the spinal cord. Most sensory neurons have one axon which is split into two branches, they transmit impulses toward the spinal cord.

Spinal cord:

The spinal cord is a tubular structure composed of nervous tissue housed within the vertebral column, runs from the base of the brain to the lower spine. Spinal cord is a component of the Central Nervous System that serves as information highway the between brain and the body which Integrates and processes information. It can function with the brain and can also function independently of the brain.

Dorsal root ganglia:

Dorsal root ganglia also known as dorsal ganglia originated as bipolar cells. They exists within the peripheral nervous system and they have special nerve cell clusters that aid in transmitting the sensory messages of pain and touch. The dorsal root ganglia receive information from sensory receptor organs and transmitting the information to the central nervous system.

The intermediate filaments of a neuron are also called __________
grigory [225]

answer: Neuro filaments

explanation:

Neurofilaments (NF) are intermediate filaments found in the cytoplasm of neurons. Together with microtubules and microfilaments, they form the neuronalcytoskeleton. They are believed to function primarily to provide structural support for axons and to regulate axon diameter, which influences nerve conduction velocity.
