A. ribosomes, the endoplasmic reticulum, and the Golgi apparatuses
Answer:
C
Explanation:
Volcanic eruption spews volcanic ash into the atmosphere that lingers and blocks out sunlight for months. This causes photoautotrophs to decrease in population numbers due to the inability to photosynthesize. This will negatively affect the heterotrophs that depend on the autotrophs for energy.
Answer:
B
Explanation:
There are usually dominant and recessive alleles. The dominant alleles mask the expression of the recessive allele. Therefore, whenever an offspring has a dominant allele of a gene, it will be expressed whether in homozygous or heterozygous form.
Answer:
B
Explanation:
A limiting factor is an element whose abundance affects the growth and distribution of a population of a species in an environment. In this case, increasing the levels of Nitrogen in the environment increases the population size and vice versa.
Mechanical energy turns into kinetic
<u>Answer</u>: Sperm cell
<u>Explanation</u>:
Amongst all the 4 options given, only the Sperm cell is a gamete (sex cell) while all the three are somatic cells.
- A <em>somatic</em> cell is the one which forms the body of an organism and contains all the genetic information.
- A <em>gamete</em> is the one which is required for the purpose of fertilization. A gamete of male fuses with the gamete of female in a process called fertilization to form a zygote to give rise to a new individual.
- A Sperm cell is basically a <em>male gamete.</em> It contains only half the amount of genetic information as the other half is contributed by the female gamete.
- This difference in the amount of genetic information arises due to the type of cell division that occurs. The somatic cells undergo mitosis whereas a gamete requires meiosis to occur for its formation.
- During mitosis there is a single round of cell division which divides the parent cell into two daughter cells each with the <em>complete genetic information</em>.
- During meiosis the cell undergoes two rounds of cell division such that a total lf 4 cells are produced each <em>with half the amount of genetic material </em>as present in the parent cell.
Since, <em>sperm is a male gamete and is formed by meiosis it contains only half the genetic information as compared to the other cells.</em>
Answer:
The cognitive abilities of an individual to learn from experience, to reason well, and to cope effectively with the demands of daily living
Explanation:
Intelligence is something that can actually be measured, even though it is not a physical, but a psychological trait. The humans had wanted to be able to measure their intelligence for quite some time, but that only became possible with the development of the modern psychology and the test specially created for this purpose. The intelligence represents the cognitive abilities of an individual to learn from experiences, how well can it reason, as well as to cope effectively with the demands of the daily living. To put it more simple, it is the ability of an individual to acquire and apply skills and knowledge in its life.
