Answer:
Because deserts are so dry, they have very low humidity—the measure of water vapor in the air. ... At night, the sun no longer heats the desert and the heat from the day doesn't stay trapped. Because of this, some deserts can get cold at night, dropping to below 40F, which is definitely coat weather.

Answer:
The result when heterozygous male and homozygous recessive female crosses is Mf, Mf, mf and mf
Explanation:
let Mm represent heterozygous male
let ff represent homozygous female
i.e Mm X ff= Mf, Mf, mf and mf
this implies that their would be two dominant heterozygous male and two recessive heterozygous female

Answer/Explanation:
Green plants can synthesise their own food by using light energy from the sun to convert carbon dioxide and water into glucose, with the release of oxygen. This process is called photosynthesis, and it occurs in specialized organelles called chloroplasts. The first stages of photosynthesis require light energy, and are often called the light-dependent reactions. The next stages occur in the absence of light energy, called the light-independent reactions.
In the light-dependent reactions, chlorophyll in the chloroplasts absorb light, converting into stored chemical energy in the form of NADPH and ATP. The high energy electron produced by light absorption travels down an electron transport chain, driving the pumping of hydrogen ions and creating a gradient. This provides the energy to produce ATP by ATP synthase
This process is used to provide for the light-independent reactions to form carbohydrates from carbon dioxide during a process called the Calvin cycle. The carbohydrates produced during photosynthesis are broken down during cellular respiration to generate ATP.
