A sex-linked trait
a Is determined by an allele on a sex chromosome
b Always affects biologically female offspring
c Connects fragments of DNA from different sources
d Is always a dominant trait
Answer:
So probably the answer is A
Explanation:
A particularly important category of genetic linkage has to do with the X and Y sex chromosomes. These not only carry the genes that determine male and female traits but also those for some other characteristics as well. Genes that are carried by either sex chromosome are said to be sex linked.
Men normally have an X and a Y combination of sex chromosomes, while women have two X's. Since only men inherit Y chromosomes, they are the only ones to inherit Y-linked traits. Men and women can get the X-linked ones since both inherit X chromosomes.

What happens when energy is transferred to a liquid? If you really know the answer from previous lessons like this, then I will award you a brainliest! Thank You!
Answer:
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. ... The denser cold liquid or gas falls into the warm areas.
Answer:
As a gas or liquid is heated, the substance expands. This is because the particles in liquids and gases gain kinetic energy when they are heated and start to move faster. ... This movement of liquid or gas, is called a convection current, and energy is transferred from one area in the liquid or gas to another.

Does a miosis cell make sex cells or body cells?
Does a mitosis cell make sex cells or body cells?
answer both
brainiest for whoever can explain the steps of the process too
Answer:
miosis creates sex cells, im sure
Explanation:
Answer:
Miosis : Miosis helps us with sex cells
Mitosis : helps us with regenerating of of body cells,
Explanation:
But there is alot more to it .
when cells of the skin and bone marrow are sites of active mitosis replacing skin cells and red blood cells that only have a limited life. Repair,regenerate the damages cells.The cells divides only once. But that does not mean that it does not plat any part in reproduction in baacteria reproduces through mitosis ( binary fission ) .
During meiosis one cell divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid. Meiosis produces our gametes (eggs in females and sperm in males).

As we move from the surface to the interior and center of the Earth, which of the following is true?
A: Temperature decreases
B: Pressure decreases
C: Density increases
D: All of the above
E: None of the above
Answer: C: Density increases
Explanation: As you go closer towards the center of the Earth, pressure increases. The layers of rock get pack tightly together, causing them to be more dense.
As we move from the surface to the interior and center of the Earth, density increases.
What is interior of the earth?Four layers, three solid and one liquid (molten metal nearly as hot as the sun's surface), make up the interior of the Earth. A massive iron ball with a diameter of roughly 1,500 miles (2,400 kilometers) makes up the deepest stratum.
The iron isn't pure; researchers think it also contains trace amounts of nickel, sulfur, and other components. Although different measurements have been made, it is most likely between 9,000 and 13,000 degrees Fahrenheit (5,000 and 7,000 degrees Celsius).
The outer core, a shell of liquid iron, is located above the inner core. This layer may be between 4,000 and 5,000 degrees (7,000 to 9,000 degrees Fahrenheit) colder but still highly hot.
Therefore, As we move from the surface to the interior and center of the Earth, density increases.

Which statement correctly explains a symbiotic relationship?
A
Mutualism is a relationship in which intestinal bacteria produce Vitamin K in humans.
B
Parasitism is a relationship in which a spider crab is camouflaged with seaweed on its back.
C
Commensalism is a relationship in which a blood-sucking mosquito feeds on the blood of a dog.
D
Predation is a relationship in which a plant grows taller in bright sunlight than in a shaded area.
The correct explanation of a symbiotic relationship is commensalism in which a blood-sucking mosquito feeds on the blood of a dog. Thus, the correct option is C.
What is Commensalism?Commensalism is a long-term biological interaction in which the organisms of one species gain benefits from the association while those of the other species neither benefit nor are harmed from the relationship. There are three main types of commensalism which include inquilinism, metabiosis, and phoresy.
An example of commensalism is the relationship between the blood-sucking mosquito which feeds on the blood of a dog.
Therefore, the correct option is C.

List the steps of translation starting with the first step
- mRNA brings the coded message from the nucleus to the ribosome
- tRNA carries amino acids to the ribosome
- The tRNA separates from the amino acid
- rRNA helps form the bonds between the amino acids
Answer:
DNA is in every living thing. In the process of transcription, mRNA reads the split DNA. Codon transfers the genetic information from the nucleus of DNA to the mRNA. The mRNA, in turn, is transformed into an amino acid sequence, via translation. This process uses an adapter called transfer RNA (tRNA), which creates the protein according to a triplet base coding system. Anticodons carry amino acid in its tRNA structure.
