4. If you just finished exercising, what happens to the amount of carbon dioxide you
exhale?!
Answers
Answer:
More Carbon dioxide is removed from the blood and exhaled in the breath
Explanation:
During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it. So, when you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.

Case study A man and woman are deciding whether to have a child. The genotype of the man includes a recessive allele for an inherited
disease. The genotype of the woman does not include this allele. Both parents have a normal phenotype. Could the child inherit the
disease? Explain your reasoning. This is a great place to use your CER (Claim, Evidence, Reasoning) skills!

Answers
Explanation: When both parents are carriers for a recessive disorder, each child has a 1 in 4 (25 percent) chance of inheriting the two changed gene copies. A child who inherits two changed gene copies will be “affected,” meaning the child has the disorder.

On the basis of blood type, you know that one of the children could not have been the son of the two adults. Does this prove that the other child is their son
Answers
Answer:
No.
Explanation:
No, Blood test can't tell us that the which child is the son of two adults, it can only be find out by DNA testing of children with the two adults. If the DNA testing matches of children to the adults then we can say that these children are the sons of two adults while on the other hand, if the DNA of two children not match with the two adults then we can say that they are not their child.

When the ______________or signal molecule is attached, the door is open for certain ________________to enter the cell. These types of receptors are important in the _________________.
Answers
Answer:
ligand; ions; ligand; ions; nervous system
Explanation:
Ligand-gated ion channels are transmembrane protein complexes that open when they bind to their corresponding ligands (e.g., neurotransmitters). This type of receptor is known to modulate the synaptic transmission between neuron cells or neuron and muscle cells. In the nervous system, ligand-gated ion channels located at sites of synaptic contact determine the ion flow in response to neurotransmitter binding. Some examples of ligand-gated ion channels include gamma-aminobutyric acid A (GABA-A) and nicotinic cholinergic receptors.

which of the following is the correct pathway of blood through the body, including the lungs?
no troll please!!!!
Answers
The correct pathway of blood through the body, including the lungs, is heart----> aorta----> body----> vena cava----> heart----> pulmonary arteries----> lungs----> pulmonary veins----> heart.
What is blood circulation?It is the circulation of blood throughout the body.
What are the two types?The two types are:
Pulmonary circulation starts with deoxygenated blood from the right ventricle where, through pulmonary arteries, it reaches the lungs (oxygenation of blood occurs), then through pulmonary veins, blood enters the heart in the left atrium.
Systemic circulation starts with oxygenated blood from the left ventricle, from where, through the aorta, it is pumped to the body, then to the superior or inferior vena cava, and then blood reenters the heart in the right atrium.
Hence, the correct answer is option b): heart--> aorta--> body--> vena cava--> heart--> pulmonary arteries--> lungs--> pulmonary veins--> heart.

Picture yourself hiking in a narrow canyon in Utah. The canyon is dry and it hasn’t rained for weeks. You see some thunderhead clouds in the sky, but not one drop of rain all day.
Nevertheless, a small rush of water starts to run through the canyon, turning it into a creek. There must have been a heavy rainfall somewhere nearby. Water runs down the sides of the canyon, forming little waterfalls. You realize that there could be a flash flood coming! You turn quickly up a side trail to higher ground before you are washed down the canyon.
What are the stimulus and response in this scenario?
A. The stimulus is the rain clouds and the response is the water in the canyon.
B. The stimulus is the appearance of water in the canyon and the response is moving to higher ground.
C. The stimulus is water running down the canyon walls and the response is little waterfalls forming.
D. The stimulus is the rain somewhere else and the response is you realize that there could be a flash flood.

D. Bacteria can replicate themselves without help from a living cell.
Answers
Answer:
d
Explanation:
bacteria can replicate themselves without help from a living cell.
Bacteria are capable of self-replication without the assistance of a live cell. So, the correct option is D.
What is Bacteria?Bacteria are ubiquitous, generally free-living creatures that are frequently made up of one biological cell. They make up a significant portion of the prokaryotic microbial kingdom. Usually a few micrometres in length, bacteria were among the earliest life forms to appear on Earth, and are ubiquitous in most of its environments.
Bacteria lack a nucleus bound to the membrane and other internal components and are consequently placed within the group of unicellular life-forms called prokaryotes. Prokaryotes have dominated life on Earth for at least three-quarters of its existence and have adapted to nearly all of the planet's biological niches. Bacteria are capable of self-replication without the assistance of a live cell.
Therefore, the correct option is D.
