The term is known as TROPHIC LEVEL...........
Answer:Tissue
Explanation:Heart muscle cells beat in unison to push blood in timing with the rhythm of the heart, at the direction of nearby nerve cells. These muscle cells could best be called. Tissue. As cell division proceeds, the cells increase in number, but also become specialized in structure and function.
Answer:
You multiply 0.5 by 20 which will give you 10 your answer is 10
Answer:
Hemophilia is a x-linked recessive inherited bleeding disorder. in this disease blood does not clot properly due to the decreased level of blood clotting factor VIII (8) or factor IX (9).
In x-linked recessive condition, the disease is transmitted from father (affected male) to his daughter and mother (affected female) to her son and skip of generation getting affected is also occurs.
- there will be 50% chance of her (S.R.) each son to be affected with hemophilia.
Explanation:
Hemophilia is caused due to mutation of one gene which is responsible for the making of proteins of blood coagulation factor viii or ix. the affected person bleeds continuously from any injury and that can cause serious issues.
here,
grandfather of s.r is affected (xₐy) and grandmother is normal (xx) will produce
↓
s.r's mother who is a carrier (xₐx) [as xₐy and xx will produce 100% carrier xₐx daughter]
↓
s.r's mother is a carrier (xₐx) but her father is normal (xy) will produce,
↓
s.r who has 50% chance of being carrier (xₐx) and 50% chance of being normal (xx) [as she is the only child] and she has a normal (xy) partner, they will give,
↓
- if s.r is a carrier (xₐx) then one of her son will be affected (xₐy) [as xₐx and xy =xₐy]
- if s.r is normal (xx) then her son will be normal (xy) [as xx and xy will give xy]
here,<u> 50% chance of her son to be affected with hemophilia</u> [as S.R of being affected is more considerable].
The animals that live in the Alpine biome have to have special adaptations to survive in it as this is a biome with very harsh conditions for big portion of the year. The temperatures are very low, the winds are strong, winter lasts for half a year or more, and there's lot of snow. All this has made the animals to develop certain traits to help them survive. Some of those adaptations are:
- thicker and longer fur for better isolation form the outside conditions
- wider paws with denser and tougher skin, helping them to move easier in the snow and avoid frostbite
- larger lungs and nostrils for easier breathing in the high altitudes
- stockier bodies so that heat can be preserved easier
- the ears and tails are small and rounded in order to avoid frost bite
- big portion of them are able to hibernate for several months
