Answer:

Karyotype

Explanation:

A karyotype is a picture of all the chromosomes in an individual. These images are analyzed by geneticists to identify structural changes in the chromosomes or to identify differences in number as is the case for Down syndrome.

Karyotyping is used to identify certain genetic diseases associated with chromosomal aberrations. This is associated with the field of cytogenetics.

pantera1 [17]

Answer:

A lethal mutation, thereby the resulting phenotype is not observed .

Explanation:

Lethal mutations are the result of genomic changes that may be lethal in certain conditions. In genetic research, this type of mutation has shown to be very useful in analyzing gene function (i.e., genes whose protein products are key for the survival of the organism in question), and they are perfect gene markers. In bacteriophages, for example, temperature-sensitive mutants of phage T4 that can not grow at temperatures higher 42°C have been identified (Edgar & Lielausis 1964).

1. The organisms at lower trophic levels have more consumable energy which provides the whale with more energy that organisms at other trophic levels.
2. Agree
3. Depending on the food chain, organisms can be on multiple trophic levels. For example, lions can be both a tertiary and secondary consumer.

What do flowers and runners have in common? how are they different?
kompoz [17]

Answer:

Both flowers and runners help a plant to reproduce.

Explanation:

Both flowers and runners help a plant to reproduce. While a flower help in sexual reproduction, a runner helps in asexual reproduction.

A flower has both male and female gamete at one place. When the pollen grains with in a flower reaches the female ovary, a new seed is produced  which has the potential to develop into new plant. In case of runner (which is a stem), the tip of the stem has the potential to grow into a new plant

IrinaK [193]

Answer:

The correct answer is "The eggs must have internal membranes".

Explanation:

Amniotes are animals that have adapted to reproduce putting eggs on land (reptiles, birds or mammals). The eggs of amniotes have internal membranes that let gases but not water pass through. This characteristics allows the embryo to breath inside the egg, and allow the egg to not dry out on land. Therefore, the eggs of the new species of animal must have internal membranes in order to allow its reproduction on land.
