In some deserts, the air temperature can change over 60 to 70 degrees in a single day. Which of these properties
would allow humans to survive in an environment that has such drastic changes in temperature?
Eliminate
A)
cold bloodedness
being endothermic
being ectothermic
being photosynthetic
Answer:
Being endothermic
Explanation:
Humans are not cold-blooded and we don't photosynthesise so only the second option applies to humans;
We produce heat internally within our bodies so we are endotherms, i.e. warm-blooded;
We shiver and have thermogenesis through metabolism to generate heat to keep body temp up and also sweating and physiological mechanisms to cool out bodies down.
Patterns of inheritance within organisms like pea plants, fruit flies, mice, and others are somewhat easy to determine since their mating practices can easily be controlled. Apart from controlling who mates with whom, what other characteristics make species like these ideal for studying genetics?
Answer: Due to following reasons these organisms are useful for studying genetics.
Explanation:
These organisms offer following characteristics which help in understanding the inheritance pattern in living organisms:
1. They allow which traits can be inherited from the parents to the offsprings.
2. These organisms are easy to grow and cultured.
3. These organisms can bred rapidly and can show many observable characteristics.

Do you think research on inhospitable plants can help botanists in other industries? Explain your answer.
Answer:
These plants grow in very difficult environments. So, researching their genes may help botanists working in agricultural areas develop crops that can grow in inhospitable areas. Also, understanding how these plants survive in harsh conditions may help conservation scientists protect plants if their environments change.

Which reaction is taking place between 1 and 3 (Look at picture)
- ammonification
- glycolysis
- photosynthesis
- respiration
Answer: respiration
Explanation:
The process of photosynthesis is taking place between the pictures 1 and 3 as these require carbon dioxide and water molecules in the presence of light energy to produce glucose molecules and oxygen gas. Thus, the correct option is C.
What is Photosynthesis?Photosynthesis is the process in which the light energy is trapped by chlorophyll of the leaves and other green parts of the plant body to convert the carbon dioxide and water molecules to produce food in the form of glucose (carbohydrate). Glucose is produced in the plants where chlorophyll is present inside the chloroplast organelle as trapping the solar energy initiates the process of photosynthesis.
Photosynthesis occurs in the plant cells because they contain chloroplast. This process involves the conversion of light or solar energy into chemical energy that is glucose molecules.
Therefore, the correct option is C.

Lysosomes digest food particles brought into a cell by endocytosis. After a vesicle containing food particles fuses with a lysosome, H+ ions are transported into the lysosome from the cytosol. This significantly lowers the pH of the lysosome relative to the cytosol and activates the enzymes that digest the particles.
Which of the following best predicts what will happen to the lysosomal enzymes if the proteins that transport H+ ions from the cytosol into the lysosome are damaged?
There are more than 60 different types of hydrolases inside the acidic compartments known as lysosomes. They control the endocytosis-mediated destruction of extracellular particles.
What is the function of Lysosomes?An organelle of a cell that is membrane-bound and houses digestive enzymes is called a lysosome. Numerous cell processes involve lysosomes.
They disassemble extra or worn-out cell components. They could be utilized to eliminate invasive bacteria and viruses.
In the digestive system of the cell, lysosomes break down materials taken in from the outside, as well as any unnecessary cell components.
Therefore, considering that there won't be any active transport of H+ ions, the lysosomal enzymes won't become active.
