Answer:
A complete fruit fly crossing requires that at the end of the crossing only offspring flies be counted
Explanation:
The fruit fly —Drosophila melanogaster— was one of the species used by Mendel to carry out his experiences related to genetics. Its rapid reproduction allowed the observation of hereditary characteristics —such as eye color and wing size— in the offspring.
Any experiment in genetics involving the crossing of fruit flies must ultimately take into account the offspring flies, their characteristics and phenotypic proportions.
Regarding the other options:
The characteristics and number of the parent flies are data already known before the crossing of fruit flies, so they do not represent a relevant data to be taken into account at the end of the crossing.

Two differences between hormones and the nervous system
Answer:
Hormones can be proteins, lipids or cholesterol-based molecules. Neurotransmitters are protein. The main difference between hormones and neurotransmitters is that Hormones are produced in the endocrine glands and released into the bloodstream where they find their movement targets at a distance from their origin. In contrast, Neurotransmitters are released into the synaptic space by a terminal of an excited presynaptic nerve cell and transmit a nerve signal to the neighboring postsynaptic nerve cell.
Explanation:
Answer:
the nervous system and endocrine system (hormones) is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.

how do ferns reproduce?
Ferns produce male and female cones.
Ferns produce spores under its leaves.
Ferns produce egg and sperms cells in the leaves.
Ferns produce flowers that contain egg and sperm cells.
Answer:
The answer is C.
Explanation:
Most ferns reproduce differently, and that involves meiosis and fertilization. When you are thinking of the typical big fern plant, what it does is, by meiosis, produces spores, and spores have half the number of chromosomes of the big parent plant. The spores are released into the wind.
Answer: The correct answer on Ody2020 is: Ferns produce spores under its leaves.

Whats the difference from the first and second law of thermodynamics
Answer:
Explanation:
the first law is the law of conservation of energy which basically means energy can't be created or destroyed in an isolated system.
the second law is that the entropy always increases in the isolated system. entropy is the measurement of the units thermal energy per unit temp.

How does color affect heat?
How would this impact various aspects of our landscape around our country?
Answer:
It depends on the shade of the color
Explanation:
Darker colors would obviously attract more heat because of the representation of vibrance and how the sun reacts to the color of something.
It impacts our landscape because darker green trees would most likely cause more wildfires!
What is a station model and what types of data are identified by a station model?
It has to be in your own words ill give brainliest
Answer:
Meteorologists created the station model to fit a number of weather elements into a small space on weather maps. This allows map users to analyze patterns in atmospheric pressure, temperature, wind speed and direction, cloud cover, precipitation, and other parameters.
Explanation:
When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis ____________ .
Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy ____________ and oxidation of fat for energy ____________ .
Overall, when carbohydrate intake is excessive, lipogenesis ____________
Increase or decrease
Answer:
When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis decreases.
The process of conversation of stored glycogen in the liver and muscles to glucose is Glycogenesis. It takes place when the blood glucose drops,below certain levels and the body cells need glucose for biochemical activities.Therefore, when there are excess CHO consumption,more glucose would be in the blood,and thus no need for glycogenesis.(breakdown of glycogen)
Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy __Increases__________ and oxidation of fat for energy ___decreases_________ .
Definitely, this is a simple logic.As the storage for glycogen is limited,excess glucose move into the blood, since they can not be converted to glycogen.The glucose is expended through cellular reduce the amount in the blood. Therefore, Gluconeogenesis, the production of glucose from non-CHO substances drops. Hence beta- oxidation drops.
Overall, when carbohydrate intake is excessive, lipogenesis increases.The process of converting excess CHO to fatty acids.Biochemically it is the process of converting the Carbon precursor of acetyl co -A to fatty acids.Therefore this increases to synthesized more fatty acids from CHO
Explanation:
Evaluate f(x) = 2x-17 for x=34
Answer: I think it is 51
Explanation:
Answer:
f(34) = 52
Explanation:
f(x) = 2x-17; x=34
1. Plug the number 34 in all the x's you can find in the equation.
f(34) = 2(34)-17
2. Solve the parentheses.
f(34) = 68-17
3. Subtract.
f(34) = 52
4. Answer: If x=34, your answer is 52.
how did wegner use climate evidence to support his hypothesis
Explanation:
Wegener used evidence of climate change to support his hypothesis. As a continent moves toward the equator, its climate becomes warmer. As a continent moves toward the poles, its climate becomes colder. But the continent carries with it the fossils and rocks that formed at its previous locations.

What chemical bond is responsible for the existence of the sugar-phosphate backbone of DNA
Answer:
Phosphodiester bonds
Explanation:
Answer:
The answer is phosphodiester bond.
Explanation:
The sugar phosphate backbone is an important stuctural component of DNA. It consists of 5-carbon deoxyribose sugars and phosphate groups. These sugars are linked together by a phosphodiester bond, between carbon 4 of their chain, and a CH2 group that is attached to a phosphate

Water is a ________ of the light dependent reaction
Answer:
Water is split during the light reaction to form oxygen
Explanation:
The hydrogen ions formed are super important for photosynthesis. They will be used to create ATP molecules. The ATP molecules will be used later on in the dark reaction (also called the Calvin cycle). The ATP molecules allow the plant cell to assemble carbon based molecules like glucose.
