Answer: c. proteasome

Explanation:

Proteasomes are extremely important multi-catalytic proteases and are involved in various cellular functions. The proteasome is an essential component of eukaryotic cells and is responsible for the ATP-dependent proteolytic degradation of most cellular proteins. They are present in the nucleus and cytosol and can represent up to 1% of total cell proteins. Proteasomes generally degrade proteins to small peptides, most of which are rapidly hydrolyzed by cytoplasmic exopeptidases. It catalyzes the rapid degradation of many enzymes, regulatory proteins, and eliminates abnormal proteins resulting from mutation or damaged proteins. The inability of this cellular organelle can lead to neurodegenerative diseases, such as Parkinson´s disease.

Ostrovityanka [42]

Answer:

When the females tend to form a solitary group, the adult males have an advantage of mating with females in different social groups thus enhancing on the productivity of the species.

Explanation:

When both the sexes of the species tend to make a group, the males and the females of the group have to mate with the members of that particular group and hence the males have restricted mating options which reduce the size of the herd. When the females have a separate social group, the males can mate with the members of different groups and raise the herd size in a short period of time. This helps in the increase in the population size and also helps in avoiding inbreeding depression which happens among small grouped animals.

Choose the statements below that are true.
Troyanec [42]

Answer:

Cells are the smallest unit of life. This is true.

Cells are important to the structure and function of living things. This is true.

All organisms are made of multiple cells. This is false, because there are many single celled organisms like bacteria.

Cells come in different shapes and sizes. This is true, as there are cells with a variety of shape and size (round shaped cocci and the elongated and flat bacillus). There are cells from squid's nervous system, called the neurons, that are comparatively very large in size than the vast majority of the other cells.
