DNA and RNA both produce proteins, but RNA copies itself and moves out of the nucleus while DNA stays inside the nucleus and produces proteins. Also DNA helps more in cell division, while RNA helps in making proteins.

Match the following terms and definitions. 1. alternative form for a specific gene (either dominant or recessive) hybrid 2. can
galben [10]

The answers would be:

1. Allele - alternative form for a specific gene (either dominant or recessive)

2. Dominant - can prevent the allele from being expressed in a pair of genes

3. Genotype - the genes present in an organism

4. Heterozygous - it is a pair of non-identical genes that influence a trait in different ways.

5. Homozygous - a pair of genes that are identical in the way they influence a trait.

6. Hybrid - offspring from a cross between parents; has different phenotypes for a specific trait.

Here's a little bit more on the topic to help you out in the future:

Alleles are variant forms of genes. Each allele is found in a specific location of a chromosome and that location determines the trait that will be expressed.

There are two types of alleles: Dominant alleles and Recessive alleles.

A dominant allele is expressed physically while a recessive allele is the trait that is masked. If both alleles are present, the dominant allele usually masks the recessive allele. This phenomenon is called <u>complete dominance</u>. There are some traits where both alleles are equally expressed, which is called <u>co-dominance. </u>

Genotype is the set of genes present in an organism that is responsible for specific traits. Phenotype on the other hand is the physical expression of the trait, which depends on the genotype of the organism.

Alleles come in pairs, they could either be homozygous or heterozygous.

Homozygous pairs consist of either 2 dominant alleles or 2 recessive alleles. The genotype would look something like this:

2 dominant :RR                 or     2 recessive: rr

Heterozygous pairs consist of non-identical alleles, or it has one dominant and one recessive allele. So the genotype would look like this:

Rr

Finally, hybrid is the cross-breeding of two different species that are genetically different. There are many examples of hybrid species like the liger and the mule. The resulting off springs express traits that are different than both parents.

If you uncovered fossils of tropical fish and palm trees, what could you say about the environment at the time the fossils forme
Ber [7]
<span>The uncovered fossils of fish and palm trees shows that Earth’s environment has changed. Due to climate change, animals and trees have adapt to it over time. Researchers have found that tropical fish species are likely to leave their homes and populate in cooler waters as the world heats. And the palm trees were found that have grown in Antartica because of the change in temperature.<span>

What kinds of molecules allow the different types of interactions between cells and the matrix?
Marat540 [252]

The receptor molecule is the ones which allow different interaction to occur between the matrix and the cell.

<u>Explanation:</u>

Receptor molecules are the protein molecules that have the ability to bind the signaling molecules at the surface of the cell in order to send signals to the matrix. Those signals on receipt<em> </em>act as the channel of communication.

Thereby, the interaction between the cell and matrix is established. Usually, this is one of the kinds of interaction. Paracrine interactions are interaction within adjacent cells whereas the endocrine interactions are interaction with distant cells.
