Answer:
The question lacks options, the options are:
A) All cells contain a nucleus.
B) All cells come from other living cells
C) All living organisms are made of one or more cells.
D) Cells are the basic unit of structure and function of all living things.
The answer is A
Explanation:
In 1830's, three scientists named; Mattias Schleiden, Theodor Schwann and Rudolph Virchow contributed to describing the basic properties of the cell, which they proposed in their so named CELL THEORY. This widely accepted cell theory has three components:
All living organisms are made up of one or more cells.
Cells are the basic and fundamental unit of life
All existing cells come from cells that have previously existed.
It was not proposed that all cells have a nucleus
The first question is the first option (4 haploid cells; 2 diploid cells).
The second question is the first option also (nitrogen).
If wrong I’m sorry but good luck! Have an amazing day!
Answer:
I'm so confused but agreed ig ?
Three nonpolar molecules that are used in everyday live are carbon dioxide (CO2), methane (CH4), and ethylene (C2H4).
Ethylene is used to make plastic and ripen fruits and methane is used to produce electricity and power garbage trucks. Besides its usage in the crucial processes of photosynthesis and cell respiration that keep us alive, carbon dioxide is important in refrigeration and is also found in fire extinguishers.
Hope this helps!
Answer:
precipitation and temperature
Explanation:
Temperature and water are considered major abiotic factors that affect species distribution in terrestrial ecosystems. The temperature can affect the distribution of terrestrial organisms due to many species maintain a constant internal temperature, while other species maintain a body temperature range that may be very different from the environmental temperature, and therefore they will not be able to carry out their metabolic functions. Hibernation is an adaptation that allows some terrestrial animals to escape temperature fluctuations. Moreover, water is another limiting factor for life, since water is critical for cellular processes. The waxy cuticle is an adaptation that allows terrestrial plants to avoid excessive water loss through transpiration.
