Unicellular organisms are living things made up of only one cell. For example, bacteria and yeast are unicellular. Multicellular organism are made up of more than one cell. Some examples of a multicellular organisms are humans and animals.
You can easily remember it because the scientific name of leech is Hirudinaria. So it secretes anticoagulant named hirudin. Which help it to feed blood longer
Answer:
Tortoises with better adaptations in shell shape and leg length were selected to exploit the food resources on each island and, thus, they were capable of having more offspring.
Explanation:
Natural selection can be defined as the process of differential survival and reproduction in a given environment due to differences in their phenotypic traits. Thus, these phenotypic traits are selected to be better adapted to their environment. As a consequence of natural selection, organisms evolve by changing their phenotype frequencies over many generations. In this case, phenotypic differences are expressed as variations in shell shape and leg length, which are adaptive traits that were selected on each island.
Missouri Compromise made provisions for federal authority in the west but prohibited the spread of human bondage.
What is Missouri Compromise?
- The Missouri Compromise Act, passed by the US Congress in 1820, admitted Missouri as the 24th state to the Union.
- Northern congressmen attempted unsuccessfully to attach amendments preventing further slaveholding after the area requested sovereignty without constraints on slavery.
- When Maine (which was once a part of Massachusetts) applied for statehood, Henry Clay brokered a deal that saw Maine admitted as a free state and Missouri admitted as a slave state.
- Slavery was subsequently outlawed in areas north of Missouri's southern boundary.
- Clay's solution highlighted the sectional divide while appearing to resolve the slavery-extension issue.

Answer:
1. BbRr
2. Black, rough fur
3. bbRR
Explanation:
1. The genotype of the parents can be seen at the top of the cross "BbRr". The genotype is what alleles the parents have. In this case, it is the alleles of two different genes - for color and texture of fur. The genotype gives rise to 4 possible allele combinations that an offspring can inherit (BR, Br, bR or br)
2. The dominant allele is usually displayed as a capital letter, and the recessive as lowercase. Without further information, we will assume this is the case. The parents are heterzygous for both traits, meaning they each carry a dominant and recessive allele for both traits. That means the dominant allele will be expressed in the phenotype. Therefore, the guinea pigs will have black, rough fur.
3. Empty box shown in the attachment. We simply read the column and row of alleles that are contributing to this offspring's genotype. We can see looking at the square that from one parent (top) the baby will inherit bR, and from the other parent (left) it will inherit bR as well. This means the baby's genotype will be bbRR
