Answer:
True
Explanation:
The Drosophila like the mammals possess X and Y chromosomes but as in males in which the XX is female and XY is male, the sex In Drosophila is not determined by the presence of Y chromosomes as a male determining factor are present on the autosomes.
However, the Y chromosome is important for males as they are involved in the formation of the sperms therefore the presence of Y is important. In the given question if the allele is present ion the Y chromosome which can reduce the size therefore the allele is passed on to the males only ans no females.
Thus, true is the correct answer.
the fly is female (Bridges 1921, 1925). Thus, XO Drosophila are sterile males. In flies, the Y chromosome is not involved in determining sex. Rather, it contains genes active in forming sperm in adults.
It is not possible to determine the twins' behaviors based on having this single gene
Answer:
midbrain, medulla, and pons
Explanation:
The brainstem (also known as truncus encephali) is localized in the posterior part of the brain, in the base between cerebral hemispheres and the cervical cord. <em>It's divided into three parts, the midbrain or mesencephalon, the pons or mesencephalon, and the medulla oblongata also known as long medulla or myelencephalon.</em> <em>In the image I added you can see the brainstem structure.</em>
Some of the brainstem functions include the regulation of respiratory and cardiac function, thermoregulation, and other functions related to vision, sleep, etc.
I hope you find this information useful and interesting! Good luck!
So, the fact that it's a specific instrument doesn't change why you need to correct the data.
However, for this question it is important to know the instrumentation.
Since respirometers are measuring the <span>C<span>O2</span>:<span>O2</span></span><span> relation, clearly having biotic material and abiotic material will change the measurements.
You should be able to figure out that the general gas law is coming into effect because of the act of cellular respiration.
In general terms, you are correcting your instrument to a known blank (you do this with scales and every other instrument).
By determining the reading for the blank (marbles) you can know the relative error of the instrument.
Taking a scale for example: You 0 the scale to a mass of importance (the amount of error you're okay with) and then use it for your measurements so you can be adequately confident of the mass you're measuring .</span>
The question is not given. You just placed some statements. Apparently, here you have some definitions to pair with the type of elements. So, I will separate the statements as per my best understanding. If the question requires anything else tell me to give you more details.
<span>1. Metalloid
Metalloid is an element that has properties in between metals and non metals, this is metalloids have some properties of both.
Then you can pair it with ---> moderate ability to conduct heat and electricity
2. noble gas
The elements that are knwon by not reacting with other elements are noble gases.
Then, pair this with ---> will not react with other elements.
3. metal:
Metals are malleable, polishes to a luster and are good conductors of heat and electricity.
Then pair metal with ---> malleable, polishes to a luster;
conducts heat and electricity well
4) non metal gaseous: non metal are poor conductors
So, pair this with ---> does not conduct heat or electricity well
Given that the question is no
