Answer:
The size of the bag will shrink due to movement of water molecules out of the bag into the beakerdue to osmosis.
Explanation:
The difference in concentration between two regions results in a phenomenon known as diffusion.
Diffusionnis the process by which molecules of a substance move from regions of higher concentration to regions of lower concentration until equilibrium concentration is reached by the two regions. Water molecules moves across regions of different concentration through a semipermeable membrane in a special form of diffusion known as osmosis.
Osmosis refers to the movement of water molecules from regions of high concentration (dilute solutions ) to regions of low concentration (concentrated solutions ) through a semipermeable membrane until equilibrium is attained.
The solution in the bag is less concentrated than the solution innthe beaker. The bag serves as a semipermeable membrane allowing water molecules to move out of it into the beaker due to the difference in concentration of the two solutions. As a result, the size of the bag shrinks while the level of the solution in the beaker rises as it becomes less concentrated.

Abe knew from his anatomy class that there are three different kinds of muscle tissue in the body. He knew lifting weights would help build the skeletal muscle and that running was good for cardiac muscle health. He was surprised to find out that his blood vessels had smooth muscle, so his exercise regimen was actually benefitting all the muscle types of his body. Correctly sort each of the characteristics into the appropriate category.

Answer:
SKELETAL MUSCELES CARDIAC MUSCLES SMOOTH MUSCLES
Explanation:
SKELETAL MUSCLES -: There are long, cylindrical, and striated skeletal muscle cells. They are multi-nucleated, which means they have more than one nucleus. This is because from the fusion of embryonic myoblasts, they are created. Each nucleus controls the sarcoplasm's metabolic demands around it. There are high energy requirements for skeletal muscle cells, because they contain several mitochondria in order to generate adequate ATP. Examples of skeletal muscles: arms and legs- The muscles that belong to the arms and legs feature in pairs. Abdomen and Back- These muscles are connected to the various sets of skeletal muscles that run across the torso.CARDIAC MUSCLES -: Cardiomyocytes have a short and narrow outline and are fairly rectangular. They are about 0.02 mm wide and 0.1 mm (millimetres) long, respectively. There are many sarcosomes in cardiomyocytes, which provide the required energy for contraction. Cardiomyocytes usually contain a single nucleus, unlike skeletal muscle cells. Cardiomyocytes, although they contain more sarcosomes, normally contain the same cell organelles as skeletal muscle cells. example - cardiac muscle is present in heart. SMOOTH MUSCLES -: Smooth muscle cells have a single central nucleus and are spindle-shaped. They range in length from 10 to 600 μm (micrometers), and are the tiniest type of muscle cell. In the expansion of organs like the kidneys , lungs, and vagina, they are elastic and therefore essential. As in cardiac and skeletal muscle, the myofibrils of smooth muscle cells are not aligned, meaning they are not striated, hence the term smooth. example of smooth muscles -: Walls of blood vessels , Walls of stomach , Ureters , Intestines , In the aorta (tunica media layer), Iris of the eye. ,Prostate and Gastrointestinal Tract.

Oxygen-rich blood is carried through pulmonary arteries from the lungs to the heart?
Answers
It is false that oxygen-rich blood is carried through pulmonary arteries from the lungs to the heart.
What is pulmonary artery?The two principal arteries leaving the right ventricle of the heart are known as the pulmonary arteries. Low-oxygen blood is seen in this lower chamber of the heart. This blood travels to the lungs through the pulmonary arteries.
The middle mediastinum contains the main pulmonary artery, as well as the pulmonary arteries that follow on the right and left. They emerge from the four chambered heart's right ventricle and carry blood to the lungs.
Right side of heart sends deoxygenated blood to pulmonary artery. Nature has made it such that this blood reaches the lungs where carbon dioxide can be released and then oxygen can be loaded.
It is true that all arteries convey oxygenated blood, with the exception of the pulmonary artery.
Thus, the given statement is false.

Explanation:

Answer:
D) All of the above.
Explanation:
The Shape of a solid does not change (with exceptions), and the atoms typically remain static with little freedom of movement.
The volume of the solid also stays exactly the same if no external adjustments are made.
The arrangements of atoms & molecules are definitive and packed together, giving little movement, therefore allowing the solid to keep form.

What is the effect if any of this mutation on the amino acid chain produced
Answers
Answer:
A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes. Changes in amino acid can be very important in the function of a protein.
Explanation:
Hope this helps
The effect if any of the mutations on the amino acid chain produces that change is called a "missense mutation," because in this type of mutation, the amino acid gets changed.
What is the significance of the types of mutations?There are many different types of mutations that occur during polypeptide formation, such as those that occur but have no effect on the overall structure and function of the enzyme, proteins, etc.; these are known as "silent mutations," while others result in single amino acid changes and are known as "missense mutations." It has many implications, such as in sickle cell anemia, where a single amino acid change causes a change in the hemoglobin structure.
Hence, the effect if any of the mutations on the amino acid chain produces that change is called a "missense mutation," because in this type of mutation, the amino acid gets changed.

EVOLUTION CONNECTION The result of mitosis is that the daughter cells end up with the same number of chromosomes that the parent cell had. Another potential way to maintain the number of chromosomes would be to carry out cell division first and then duplicate the chromosomes in each daughter cell. Do you think this would be an equally good way of organizing the cell cycle
Answers
Answer:
No, because it would lead to chromosome mosaicism
Explanation:
Chromosomal mosaicism can be defined as the presence of two or more cell populations with a distinct number and/or type of chromosomes in the cells of an organism. If the cell would split before chromosome duplication, it would lead to the fact that some cells would have one chromosome of the homologous pair being duplicated, while other cells would have duplicated the other one. In consequence, this process would produce a genomic imbalance between different cell populations that would be expected to be lethal for the organism.
