Answer:
Transportation of substances in cells, where they travel against the concentration gradient. However, it requires ATP to do so.
Explanation:
Crayfish are invertebrates which means they don't have a backbone. They are also arthropods, which means that they have a protective exoskeleton on the outside of their body. Other arthropods include insects, spiders, and centipedes. Crayfish continually shed their exoskeleton and regrow a new one. During this transition is when they are most vulnerable to predators because they aren't protected by their outer shell.
Crayfish are found all over the world in many different freshwater environments, such as rivers, creeks, springs, and swamps. But this doesn't necessarily mean that you will be able to find them. They are somewhat cryptic because they dig out homes for themselves under rocks and blend in well with their environment. Crayfish will ardently defend this dwelling against intruders using their strong front claws
The correct answer is: B) Different traits are inherited separately.
Mendel’s conclusions as a result of his experiments with dihybrid crosses are known as Mendel’s laws.
• Mendel’s law of Segregation: During the gametes formation (meiosis), alleles are separated so that each gamete carries only one allele for each gene
• Mendel’s law of Independent Assortment: The segregation of alleles of one gene is independent to that of any other gene
Mendel also defined the Principle of Dominance: Recessive alleles will be masked by dominant alleles when are together in heterozygous genotype.
The answers would be histones; nucleosomes.
Sentence form: In the nucleus, DNA is wrapped around histones to form nucleosomes.
