The microscope can be used to demonstrate the segregation of chromosomes during cell division. The law of segregation of characters is a Mendel's Law.
Each allele or gene variant is located at a specific chromosome location known as a gene locus.
The Law of Segregation indicates how one offspring receives one allele from each parent for each locus in a diploid organism.
The development of microscopy confirmed the idea that offspring receives one allele (which is located at a specific chromosome) from each parent for each gene locus.

Why are leaves green:
explain the effect of germination on pea seed respiration
Answer:
"The affect of germination on the rate of cell respiration in peas is that in peas that are germinated, the rate of cell respiration is higher because the cells are growing/going through mitosis which requires energy/ATP in order to be carried out which is generated through the process of cellular respiration."

What is a Objective Summary on Global Warming?
Answer:
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
Explanation:
Answer:
The study, published last month in the journal Geophysical Research Letters, found that climate change is making summers hotter and longer, while shrinking the three other seasons. ... They found that over the nearly 60-year period, summers grew from an average of 78 to 95 days long

What is the difference between permanent gases and variable gases in the atmosphere?
Answer:
the difference is that permanent gases have larger residence times and Variable gases have shorter residence times
the difference between permanent gases and variable gases in the atmosphere is permanent gases are gases that have a very low dew point.
What are the characteristics of the atmosphere?The Earth's atmosphere is basically composed of a mixture of gases, being 78% Nitrogen, 21% Oxygen and 1% Argon. In addition, traces of carbon dioxide, water vapor and other gases are found, but in very small amounts.
In this way, permanent gases are gases that have a very low dew point.

Explanation:
1. Describe the flow of energy from the sun to a producer, like grass, and then to a consumer, like a rabbit. Type your answer here:
Explanation:
The Sun then provides energy to the grass through the process of photosynthesis. The rabbit eats the grass, and the rabbit absorbs its energy. Finally, the snake eats the rabbit, and it absorbs the rabbit's energy. Energy travels from the Sun and moves through the ecosystem with each consumer along the chain.

12. During the process of photosynthesis, energy from the Sun is converted into A. chemical energy in the bonds of inorganic molecules B. chemical energy in the bonds of organic molecules C. enzymes used to produce inorganic molecules D. enzymes used to produce organic molecules
Eliminate and explain pls
Answer:
Explanation:
A. Inorganic molecules are rarely present in the human body, and the products of photosynthesis only contain one inorganic molecule (a molecule without carbon), [tex]O_2[/tex].
B. This is correct because when looking at the photosynthesis equation you have [tex]H_2O[/tex] + [tex]CO_2[/tex] + Sunlight = [tex]C_6H_{12} O_6[/tex] + [tex]O_2[/tex] Now illustrating this conversion, the [tex]O_2[/tex] Was made from the breaking of the bonds, so no new bonding was formed, this is the only inorganic molecule. The organic molecule, glucose, or the C6H12O6, was made combining the ingredients H2O and CO2. In order to combine the components used to make the glucose, the energy from the sun helps with the exchange of electrons and facilitates the bonding to make the organic molecule glucose.
C. Sun energy can not be converted into energy used to create enzymes
D. Same as C

in all organisms, certain genes are expressed at any given time while other genes are not. both prokaryotes and eukaryotes regulate gene expression at the transcription stage. however, the greater complexity of eukaryotic cells makes it possible for gene expression to be regulated at many other stages as well. the diagram below shows different stages at which gene expression may be regulated in eukaryotes.
Answer:
The process of turning genes on and off is known as gene regulation. Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for examp
