The answer would be an example of adaptation i’m pretty sure .
Answer;
C. His mother carried at least one allele for that trait
Explanation;
-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.
-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.
-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.
Resultant force = mass × acceleration, therefore acceleration = resultant force ÷ mass
Resultant force = 19 - 1.7 = 17.3 N
acceleration = 17.3÷2= 8.65 ms-2
Answer:
2: Liquid
Explanation:
Liquid has no shape (think of pouring water from a bowl to a cube, it doesn't keep the same shape) but has the same volume (from bowl to cube is still the same volume)
Hope this helps, have a nice day :))
There are some people disagreeing with me, so here are the others:
<em>(which is totally okay, just wanted to clear it up!)</em>
Solid: Has a definite shape and a definite volume (<em>a cube will stay a cube</em>)
Liquid: Has no shape, but definite volume (<em>will change shapes but has same volume</em>) <u>(answer)</u>
Gas: No shape, no volume (<em>will change shapes, but also does not have a set volume</em>)
Plasma: No shape, no volume (<em>ionized gas</em>)
Answ
Left - antigen
Top Right - antibody
Bottom right - B cell
Explanation:
Antibodies (top right label) are Y shaped proteins involved in the detection of pathogens. They specifically detect molecules associated with pathogens called antigens (left).
Antibodies are produced by B cells (bottom right) which are a specialised class of immune cells that make up part of the adaptive immune system. B cells are often referred to as white blood cells.
