A new highly nutritious crop is going to be planted in an area where it has never been planted before. Which is the most likely outcome of such an event?

Answers

Answer 1

Answer: It will threaten local biodiversity.

The new plants planted in an area where they have never been planted before are called introduced species. They can greatly affect local ecosystem. In the new area, they have no natural predators and are able to spread. If they spread beyond the area they are planted, they become invasive species which can overgrow native biotopes and are a great threat to the local biodiversity. This could lead to the extinction of some native species.

Answer 2

What is the phenotypic ratio for a cross where both parents are heterozygous for both high-voice and sharp claws?
In studies of identical twins reared apart, similarities noted would most likely be due to_______ factors.

Some animals, such as cows, normally produce only one offspring from each mating. If a cow showed a dominant phenotype, why would a typical testcross be a difficult way to determine the genotype of that animal?

Answers

Answer:

Because of insufficient number of offsprings to determine the result of test cross.

Explanation:

Normally, in genetics, a test cross is a cross between a dominant phenotype (genotype unknown) and a homozygous recessive genotype in order to determine the genotype of that dominant organism.

The result of the test cross is obtained when a 1:1 phenotypic ratio is produced for each trait i.e. 1 dominant trait: 1 recessive trait showing that the parent is heterozygous while all the offsprings will show dominant traits if the dominant phenotype was homozygous. Hence, more than one offspring is required to be able to conclude

In this question, the cow only produce one offspring which may be DOMINANT for the observed trait making it difficult to know if other offsprings will all be dominant or some of them recessive. Hence, it is not a sufficient number needed to determine the genotype from the phenotypic ratio of offsprings.

Fish are classified as vertebrates because they havea. a brain.
b. a backbone.
c. two germ layers.
d. bilateral symmetry.

Answers

B, a backbone.

Not A, because we know some species that aren't vertebrates and have a brain.
C. two germ layers, isn't a characteristic specific to vertebrates.
d. bilateral symmetry, no for the same reasons as A.

the answer is b) a backbone

Can animals see in the dark better than humans?

Answers

Yes. Because their eyes give light they do. Just joking. Eyes reflecting is from other light sources. But they do have better night vision. Most of nocturnal animals have bigger eyes or pupils, which make it easier to catch up environmental light.
