Answer:
Telomeres
Explanation:
Telomeres are present at the ends of chromosomes and prevent the lose of genes. They shorten as a person ages. Thus lengthening them may slow down age related problem.
The main difference is that organisms that have similar characteristics could be in the same species or have common ancestors
Answer:
True
Explanation:
Facultative anaerobes are bacteria who used to grow in the aerobic condition but when oxygen becomes deficient they can switch to anaerobic mode and obtain energy through fermentation. So facultative anaerobe normally lives in aerobic condition but can survive in anaerobic conditions too.
So as facultative anaerobes normally grows in aerobic condition they grow well in incubator shelf but in anaerobic condition like anaerobic jar or in a candle jar they will show moderate growth because it is not the ideal condition for them to grow. Therefore the statement is true.
Answer: Cell membrane has many properties which is stated below.
Explanation:
The cell membrane allow one cell to communicate with other cell. It is the cell membrane which is directly in contact with the cell membrane of the another cell.
The cell membrane also serves as a channel for the transport of materials from the outside to inside and vice versa.
It also provides stability to the cell. It combines with the carbohydrates and provides immune response and cell recognition.
Wave of option A has the highest frequency.
Option A.
<h3><u>Explanation:</u></h3>
Frequency is defined as the total number of complete waves in an unit time. A complete wave consists of a complete cycle of the amplitudes of waves.
In all the figures, we see transverse waves. They have the mean position denoted by a straight line, and the waves do oscillate up and down to complete a full cycle. The most number of waves in a given time has the highest frequency. If we count the full number of waves in the particular given time, Wave A has 5.75 complete waves, wave B has 3.5 complete waves, wave C has 2 complete waves and the wave D has 2.75 complete waves. So the wave A has highest number of complete oscillations in a given time. So wave A has highest frequency.
