Answer:

vestigial structures

Ostriches have wings but do not fly, and humans have an appendix with no apparent function, whales have bones for their back legs, which are examples of vestigial structures because they were once functional but are no longer.

What is the importance of the vestigial organs in animals?

Vestigial organs have lost much or all of their ancestral function in the evolution process, for example, ostriches have wings that have lost the ability to fly and are now used for balance and courtship displays. The human appendix is another vestigial organ that once had digestive function but no longer does.

Hence, ostriches have wings but do not fly, and humans have an appendix with no apparent function, whales have bones for their back legs, which are examples of vestigial structures because they were once functional but are no longer.

Answers

Answer:

A nutrient is a substance or a chemical compound required by the animal for these productive purposes .

Explanation:

Nutrients are essential compounds and macromolecules needed for a variety of metabolic processes.  Animals show heterotrophic nutrition by consuming organic matter like lipids, fats, and proteins.

Food provides essential vitamins, amino acids and minerals that are used as cofactors and coenzymes in chemical reactions.

For example, animals use carbohydrates as fuel for all metabolic processes.

Liverworts, like the ones shown here, are nonvascular plants. They do not grow tall. Explain how the tissues in liverworts affect their size.

Guys I'm so confused. Please help!

Answers

Answer: The tissue structure of the liverworts restricts them to a type of environment that affects their size.

Explanation:

Nonvascular plants, also called the Bryophytes in Kingdom Plantae, are simple plants that grow in damp places on land and as the name implies, are non vascular plants( that is, they lack vascular tissues). There are three types of nonvascular plants which includes:

--> Mosses

--> liverworts and

--> hornworts.

Liverworts are restricted to a particular size through the type of tissue they have ( non vascular) because it predisposes them to lack conducting vessels like the phloem and xylem found in vascular plants which aids in conducting water and food to various parts of the plants. Also they do not grow tall like the vascular plants because they lack the qualities that will enable them do so, such as roots, stems and leaves.

Nonvascular plants are low-growing, reproduce with spores, and need a moist or damp environment.

Which of the following is true about mutations?
All mutations are harmful.
Every genetic mutation is expressed as a phenotype in the organism.
Mutations can be environmental or genetic.
Only some mutations involve a change in the DNA sequence.

Answers

Answer:

Mutations can be environmental or genetic

Only some mutations involve a change in the DNA sequence. Therefore option D is correct.

Mutations are changes in the DNA sequence of an organism's genome. Not all mutations are harmful; some can be beneficial or neutral.

Beneficial mutations can lead to advantageous traits, contributing to the organism's survival and evolution. Neutral mutations have no noticeable effect on the organism's phenotype.

Additionally, not every genetic mutation is expressed as a phenotype in the organism. Some mutations may occur in non-coding regions of DNA or be masked by other genetic factors.

Mutations can be caused by various factors, including environmental factors (e.g., radiation, chemicals) and genetic factors (e.g., errors in DNA replication, recombination).

Therefore option D Only some mutations involve a change in the DNA sequence is correct.

Purple flowers are dominant to white flowers. A heterozygous purple flower is crossed with a white flower. What are the probabilities of the phenotypes and genotypes of their offspring?

Answers

Answer:

50% probability of Pp (purple) or pp (white) genotype.

Explanation:

P = purple gene

p = white gene

Punnet squares show the possible genotypes and probabilities of each genotype in the offspring of a cross:

Purple flower genotype (heterozygous) = Pp

White flower genotype = pp

Punnet Square:

[tex]\left[\begin{array}{ccc}&P&p\\p&Pp&pp\\p&Pp&pp\end{array}\right][/tex]

Potential genotypes for offspring are Pp and pp;

According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;

This means 2 should be purple and 2 white;

Or, there is a 50% chance of having either genotype, of being purple or white.

Let us assume the following:

Flower color is represented by the allele A.Hence, the dominant purple color would be A, while the alternate white color would be represented by a.

From the above assumptions, a heterozygous purple flower would have the genotype Aa, while a white flower would have the genotype aa.

Now, crossing the two flowers:

       Aa    x    aa

   Aa   Aa   aa   aa

From the results of the cross, the offspring's genotypes, phenotypes, and their respective probabilities would be as follows:

Aa - purple color - 1/2aa - white flower color - 1/2

In order words, the cross will yield offspring with purple color flower (genotype, Aa) and white flower color (genotype, aa) each with 1/2 probability.
