Answer:
The definition of stroke volume is the volume of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction.
Explanation:
The stroke volume is the volume of blood pumped from the left ventricle per beat. It is calculated by using the measurements of ventricle volume from echocardiogram and subtracting the end systolic volume from end diastolic volume.
Answer:
Stroke volume is the volume of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction
Explanation:
The left ventricle is one of the four chambers in the heart that pumps blood full of oxygen to the body. Stroke volume is basically how much blood pumps out of it per beat.

Please help I have one more attempt. I need help labeling the upper muscles of the arm.
There are four muscles in the upper arm. These muscles are Brachialis, Biceps brachii, triceps brachii, and coracobrachialis.
What is the function of muscles in the upper arm?The upper arm has many muscles which are arranged in different compartments. The muscles in the upper arm are the muscles that connect the scapula with the thorax and are responsible for most of the movement of the scapula. The muscles that link the humerus are responsible for the movement of the arm. The muscles in the arm or the forearm move the arm, wrist, and hand.
The humerus is where the muscles that move your arm are located. The humerus is made up of the following muscles: Tricep, Biceps, Brachial, and Bicepsioradial. The 20-plus muscles that cause the majority of wrist, hand, and finger movement are located along the arm. The labeled image of the arm is attached below.

What do spindle fiber and flagella have in common:
Select one:
a. They are examples on a structure called a microfilaments
b. They are all structures found in prokaryotic cells
c. They are microtubules
d. They are found in the nuclei of eukaryotic cells
Answer: c
Explanation: Spindle fiber: is a microtubules that comes out from the centrosomes when the cell is preparing for division. They are responsible for the segregation of sister chromatids and movement of chromosomes during mitotic and meiotic division.
Flagella: a slender threadlike structure, especially a microscopic appendage that enables many protozoa, bacteria, spermatozoa, etc. to swim.The thread-like structure is called chromosomes.
This can conclude that microtubules are common in spindle fiber and flagella.

Define Siamese twins
Answer:
Conjoined twins are two babies who are born physically connected to each other. Conjoined twins develop when an early embryo only partially separates to form two individuals. Although two fetuses will develop from this embryo, they will remain physically connected — most often at the chest, abdomen or pelvis.

QI the father
13. A father and mother claim they have been given the wrong baby at the hospital. Both parents are
blood type A. The baby they have been given is blood type o. Does the genetic evidence support
their claim?
No, the claim is not based on scientific evidence because to heterozygous parents with genotype AO may have offspring with O phenotype and therefore OO genotype (proportion 1/4 of descendence).
What is the ABO blood type?The ABO blood type is a group of phenotypes controlled by a single locus, which is based on the alleles that encode surface antigens in red blood cells. The O phenotype is due to the recessive allele, while the A allele is dominant and therefore masks the O allele in heterozygous individuals.
Therefore, we can conclude that parents having the AO genotype may produce offspring with OO genotype

Al wonders if adding salt to water will affect how long it takes the water to freeze. Al thinks that salt water will freeze more quickly than fresh water. He decides to check his hypothesis by conducting an experiment. Al takes two ice trays and fills one with distilled water and the other with distilled water that has two tablespoons of salt added. He makes sure he puts exactly the same amount of water in each ice tray. Al takes the trays and puts them side by side in the freezer. Al checks the ice trays every 10 minutes to see if the water in each tray has begun to freeze. Al finds that after 20 minutes the water in the ice tray without the salt has started to form ice, while the ice tray with the salt water is still completely liquid.
What is his hypothesis?
a. Salt water freezes slower than fresh water.
b. Water freezes in a freezer
c. Salt water freezes faster than fresh water.
d. water will freeze in 20 minutes
salt water freezes slower than fresh water
what happens if we do not eat food ?
Answer:
If we do not eat food we will not get energy.
Answer:
When someone doesn't eat food, the effect might surprise you. That person will not die immediately, they might pass out and starve but you can go a long time with out eating, sometimes maybe a week! But that is what happens when you do not eat food, now if you do not drink water for a long time, you might actually die. Sometimes, you can't even spend a day without drinking water.
So, when you don't eat food you will not die, just starve. But when you don't drink water, you will die.
