It’s the last one.
All of these are parts of the cell theory.
Ecdysis
Ecdysis is the name of the process in which an arthropod sheds its exoskeleton and forms a new one.
Ecdysis is the process in which an arthropod or an insect shed its outer cuticle (exoskeleton), and forms a new one. Ecdysis is an essential process in the growth and development of organisms. In arthropds, this process takes place after various steps that are caused by a hormone (ecdysone) that is secreted from glands behind the brain. Organisms utilize high amount of energy while forming a new cuticle, and the old cuticle that is shed in this process is known as exuviae.
Answer:
Mrs. Ritter, whose blood type is B (Bi) is right in claiming that Ian - blood type A (Ai)- is the father of her baby, with blood type O (ii). Ex-boyfriend AB (AB) cannot be the father.
Explanation:
The blood type, according to the ABO system, is determined by the presence or absence of surface antigens A and B. In addition, genotypes can be co-dominant, in the case of A, B and AB, heterozygous (Ai or Bi) and recessive, in the case of group O (ii)
- <em>
</em><u><em>Type A</em></u><em> contains the antigen A and its genotype can be AA or Ai.
</em>
- <u><em>Type B</em></u><em> contains the antigen B, whose genotype can be BB or Bi.
</em>
- <u><em>Type AB</em></u><em> contains both antigens and a single genotype expression AB.
</em>
- <u><em>Type O</em></u><em> blood lacks surface antigens, its genotypic expression being ii.</em>
According to this, to check if Mrs Ritter's baby is Ian's child, a crossing can be done:
♂ Ai
♀ Bi
Alleles A i
B AB Bi
i Ai ii
<u>Ian and Mrs Ritter have a 25% chance of having a child with blood type O (ii), so the baby may be Ian's child</u>.
To find out why the ex-boyfriend can't be the father
♂ AB
♀ Bi
Alleles A B
B AB BB
i Ai Bi
It is not possible that Mrs. Ritter's ex-boyfriend is the father of the baby, as the possible offspring in the crossover are A, B or AB.
Answer:
salt draws the liquid out of the snail by moving the liquid from a low concentration to a high concentration to balance the concentration of salt and liquid between the snail and salt barrier.
Explanation:
salt pulls the liquid from the snail. because snails are slimy and filled with liquid, when coming in contact with salt the liquid from the snail tries to balance out the concentration of liquid by leaving the snail and binding with the salt which dehydrated and kills the snail.
