why are women often carriers of X linked traits but rarely affected by them?
Answer:
X-linked inheritance means that the gene causing the trait or the disorder is located on the X chromosome. Women have two X chromosomes; men have one X and one Y. Genes on the X chromosome can be recessive or dominant. Their expression in females and males is not the same.
Answer:
Women have 2 X chromosomes, unlike men who have XY. In women, a recessive allele on one X chromosome is often masked in their phenotype by a dominant normal allele on the other.
Explanation:
In informal words, if you have an X-linked trait that is recessive and are male, you will be affected cuz there is no other X to "override" that recessive trait because Y is (as we know) non-coding. Whereas if you are female, both of your Xs would have to carry a recessive trait for you to be affected, thus it is rarer for women to be affected by X-linked traits.

A gene with the sequence ATTCATTCA underwent duplication after a few generations. Which sequence represents this gene after the mutation?
Answer:
The sequence would be ATTCATTCA.
Explanation:
Usually, when a sequence is duplicated, one of them becomes a non-coding. It's just like a computer. There can only be one specific file, or else a duplicated one will just replace the existing one, if you allow the file to do so. Same with DNA. This is why most of our DNA have no function and why we lost genetic abilities such as being able to produce our own Vitamin C.
So instead of the new gene being ATTCATTCAATTCATTCA, it's simply ATTCATTCA. You simply cannot have duplicates, just like computer files. I wish I could share an amazing video by PBS Eons giving a great explanation about genes and stuff, but sadly Brainly doesn't like such stuff, so just search up in ㄚㄖㄩㄒㄩ乃乇 (ebuTouY) "genes we lost along the way" and it should be the first video that pops out. Trust me, it's a great video, it's much better than my explanation.

[tex]\begin{array}{lcl}Earth's \ Orbit&&Moon's \ Orbit\\Travels \ around \ the \ Sun &&Travels \ around \ Earth\\Takes \ 365.25 \ days&&Takes \ 27.3 \ days \end{array}\right][/tex]
Explanation:
The Earth is a planet which is a tern used to describe large bodies that revolves around a star.
The star around which the Earth revolves or travels around is the Sun, and the path of the Earth's motion is known as the Earth's orbit. The time it takes the Earth to travel round the Sun is 365 1/4 (365.25) days
The Moon is a natural satellite of the Earth, therefore, the Moon travels or revolves round the Earth. The Moon is about 27% the size of the Earth and it takes the Moon about 27.3 days to travel around the Earth.

Are the structures that unicellular and multicellular beings have developed to perform nutrition the same or different? Why?
Explanation:
Cells function differently in unicellular and multicellular organisms, but in every organism, each cell has specialized cell structures, or organelles, of which there are many. These organelles are responsible for a variety of cellular functions, such as obtaining nutrients, producing energy, and making proteins.

An astronomer measures the distance to two stars using the parallax method. When comparing the placement of the stars six months apart, the star that is further away: A. Changes position the most B. Changes position the least C. Appears brighter D. Appears dimmer
Answer:
I would say A but im not 100% sure
Explanation:
The parallax method uses the angle to measure the distance of the objects in space. When the method is used 6 months after then, the star further away changes its position the most. Thus, option A is correct.
What is the parallax technique?The parallax method determines the displacement of the object in the space when viewed from the line of sight and is determined by the angle of the inclination of the shift.
It is used to measure the distance of the planet to the nearby stars and is measured again after six months. It is the change of the position of the object or the celestial body with respect to the observer's position.
Therefore, the star located farthest will change its position the most.

Kenneth and Catherine Lohmann of the University of North Carolina explored the orientation or direction-finding abilities of loggerhead sea turtle hatchlings under varying magnetic conditions. Hatchlings were placed in a tank of water in a laboratory either in the natural magnetic field of the earth OR in a reversed magnetic field in which north and south were flipped. The researchers then measured the direction that the hatchlings swam. The experiments were carried out in the dark and at night since that is when most newly hatched turtles migrate from their sandy nests into the ocean. The results of the Lohmanns' experiments are most likely to be considered credible if Group of answer choices a great deal of time had been spent collecting hatchlings and running experiments. the experiments were funded by a government grant. the results were published in a peer-reviewed journal. the Lohmanns are famous scientists.
Answer:
the results were published in a peer-reviewed journal.
Explanation:
When the results of any study or a research is published in a well renowned and a peer reviewed journal, then the study is considered to be credible and authentic and is accepted by the intellectual society.
In the context, two young scientists are performing an experiment on the direction finding or the orientation finding abilities of the loggerhead sea turtle which are hatching under the varying magnetic fields.
The finding of these experiment or the result will be considered credible only when the results of the experiment will be published in a peer reviewed journal.
Advocates for organic farming claim that their methods result in a number of benefits to farmers, consumers, and the environment. Scientists now plan to study the claims that organic farming advocates make by developing testable hypotheses about the economic and environmental benefits of growing organic foods. The scientists plan to collect data from farmers and other producers. Which hypothesis should the scientists use
Answer:
''Organic farming reduces the cost of farming that benefits the farmers economically and also better the environment.''
Explanation:
The hypothesis i.e. ''Organic farming reduces the cost of farming that benefits the farmers economically and also better the environment.'' This hypothesis can be tested by the scientists by taking two fields in different location having same environmental conditions. One field they apply conventional farming whereas other field apply only organic materials and no chemicals. We can see that the cost on expensive fertilizers, pesticides and weedicides can't used in organic farming so it is economically benefitted to the farmers as well as no pollution occurs which happens due to the use of chemicals. Moreover, the price of organic food is 3 times higher due to its non-hazardous nature.

Answer:
The correct answer is - d. the idea that substances can produce germs on their own.
Explanation:
Spontaneous generation is an obsolete theory or idea that supports the production of living things and substances from non-living substances and things.
This purpose is that the living creatures could arise from nonliving matter. In microbiology, it is an idea that says that substances can produce germs on their own even if the substances are not similar.

Gina is studying a cell under a powerful microscope. The cell does not contain membrane-bound organelles.
Which cell is Gina most likely studying?
The cell that Gina is studying under the powerful microscope does not contain membrane-bound organelles. Hence, it is most likely a prokaryotic cell.
Prokaryotic cells differ from their eukaryotic counterparts in that:
they lack nucleusthey are smaller in sizethey lack membrane-bound organelles such as mitochondrion, chloroplast, etc.Prokaryotic cells lack nucleus and as a result, their genetic materials lie freely within the cytoplasm. They are also smaller in size when compared to eukaryotic cells with the former's size ranging from 0.1 to 5 micrometers and the latter ranging from 10 to 100 micrometers. Specialized organelles such as mitochondrion and chloroplasts are lacking in prokaryotic cells due to their primitive nature.
Therefore, once a cell is known to lack membrane-bound organelle, it will most likely be a prokaryotic cell.
