Spongy bone has trabecular which serve as reinforcing plates against a force. The loss of spongy bones causes weakening of the internal support that the compact bone requires and the entire bone breaks.
Answer:
A. Cell membrane is the outer layer of the cell that plays a role as the barrier between the internal and outer environment of the cell by regulating by allowing particles or substances to enter or exit the cell. It helps in maintaining the internal environment of the cell by allowing certain molecules to enter and stop other molecules.
B. Phospholipids bilayer is the part of the plasma membrane that makes it selective permeable. The plasma membrane does not allow ions with charges on the side of the molecules directly sodium, potassium, and many other ions are examples of this. Ions can enter or exit the cell with the help of the transporters or complexes.
C. There is hydrophilic-head and hydrophobic-tail present in the phospholipid bilayer in the structure of the cell membrane which makes it selectively permeable.
D. For active transport of molecules, the movement of molecules is always against the gradient which means movement from lower concentration to a region of higher concentration that requires energy (ATP).
The answer is Integrated Pest Management. IPM involves integrating
practices in an effort to drastically reduce the population of a pest, such as
mosquitos, to below the economic injury level (EIL) and reduced risks to human
health population. IPM practices should be safe and involve the control the
pest rather than eradicate.
The correct answer is D. House cats, lions, and tigers belong to the same class and family.
Explanation:
Taxonomy classifies animals using different levels such as kingdom, family, order, species, etc. that show the features of the organism and its relationship or similarities with others. In the chart presented, the only level that is different for the three animals is the last one, which is the species level because in this the cat is classified as Domesticus, the lion as Leo, and the tiger as Tigris. This implies the other levels including the class (Mammalia or mammal) or family (Felidae) is the name of the three animals. This makes the last answer correct and shows these three animals are closely related.
The correct answer would be nucleic acid in which includes DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA and RNA are the chemical substance which constitutes the genes. They carry genetic instruction that can be found in genes.
