Behavioral and antennal responses of drosophila suzukii Diptera Drosophilidae to volatiles from fruit extracts. environ. Entomol.
Drosophila melanogaster, recognized colloquially because the fruit fly stays one of the most usually used model organisms for biomedical science. For multiple hundred years,
Drosophila is derived from the Greek phrase drósos method dew loving. They belong to the Droso Aphididae family and are maximum regularly called fruit flies or regularly called vinegar, wine, or pomace flies. Their fundamental distinguishing individual is to stay on fruits, which are ripped or rotten.

During the Precambrian, Earth's first atmosphere is theorized to have been composed of a poisonous mixture of helium and hydrogen gases. When Earth's crust began to cool, the makeup of the atmosphere changed.
Answer:
Yes.
Explanation:
Yes, early Earth's atmosphere was formed from the poisonous mixture of helium and hydrogen gases. But with the passage of time when Earth's crust began to cool, the composition of the atmosphere changed and carbondioxide and water concentration in the atmosphere increases due to carbondioxide gas emission from the volcanoes and evaporation of water from water bodies present on the surface of earth.

3. Why is it necessary for the cell to grow and duplicate its DNA before the start of meiosis?
Answer:
Since the cell is dividing it needs two copies of it's DNA. One is kept by the parent cell and the other is passed to the daughter cell..... So this process of duplicating DNA is very important, because the daugher DNA cell will likley die.
Explanation:
Give an example of a single trait that is affected by more than one gene.
Answer:
Sometimes a single gene may affect more than one trait. This is called pleiotropy. An example is the gene that codes for the main protein in collagen, a substance that helps form bones. The gene for this protein also affects the ears and eyes.
Explanation:
How many times do cells undergo Mitosis in order to become a gamete?
Answer:
two
Explanation:
When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes.
Answer:
Cells do not undergo mitosis to become gametes although Somatic Cells go through Mieosis 1 & 2 to become gametes.
Explanation:
Specifically a somatic cell is split twice where on parent cell ends up into 4 daughter cells through Meiosis 1 and 2
Mitosis produces the exact same cell so if you did mitosis on a somatic cell it would never happen. But if you did it on a cell already a gamete it would only take one division
The genes for the traits that mendel worked with are either all located on different chromosomes or behave as if they were. How did this help mendel recognize the principle of independent assortment?.
Mendel recognized the principle of independent assortment by working with the genes located on different chromosomes as otherwise, his dihybrid crosses would not have produced a 9:3:3:1 ratio for F2 phenotypes.
Mendel's law of independent assortment states that during a dihybrid cross, the assortment of each pair of traits is independent of the other. This means that, during gamete formation, one pair of traits is separated from another pair of traits independently. The genes for the traits that Mendel worked upon were located on different chromosomes or behaved as if they were. This feature helped Mendel to conclude with his finding as a law of independent assortment.
Gregor Mendel performed dihybrid crosses between organisms having two different traits: seed color and seed shape. One parent was homozygous dominant (YYRR: Yellow round) and the other was homozygous recessive (year: green wrinkled) for two different traits. He produced a heterozygous dominant trait ( YyRr: Round yellow) in the F1 progeny. When F1 progeny was self-crossed, he observed that the phenotypic ratio was 9:3:3:1. This means that the F2 progeny resulted in four different combinations of seeds: wrinkled yellow, round yellow, wrinkled green, and wrinkled yellow seeds.
With the genes located on different chromosomes, it was made easier for Mendel to observe the phenotypes in F2 progeny.

60 POINTS!! PLEASE HELP!!When the level of blood testosterone has increased past its set point, a negative feedback signal will be sent to the hypothalamus.
Based on the diagram, what will be the result of this signal?
A) The hypothalamus will stop production of gonadotropin-releasing hormone. As a result, the production of follicle-stimulating hormone will increase and testosterone levels will decrease.
B)The hypothalamus will stop production of gonadotropin-releasing hormone. As a result, follicle-stimulating hormone will no longer be produced and testosterone levels will start to decrease.
C)The hypothalamus will stimulate production of gonadotropin-releasing hormone. As a result, the production of follicle-stimulating hormone will increase and testosterone levels will increase.

Gated ion channels are open and close in response to a stimulus.
What is a stimulus?A stimulus in physiology is a perceptible alteration in the physical or chemical composition of an organism's internal or external environment. Sensitivity refers to an organism's or organ's capacity to recognize external stimuli and respond appropriately (excitability). As with touch receptors in the skin or light receptors in the eyes, sensory receptors can pick up information from both within and outside the body. Chemoreceptors and mechanoreceptors are examples of internal sensory receptors. A stimulus can trigger a response via stimulus transduction when it is recognized by a sensory receptor.
