Vacuoles are found in plants, animals and single-celled organisms. In plants, vacuoles can occupy up to 90% of the cell while in animals, vacuoles are much smaller and also help store ions and nutrients. Single celled organisms that live in aquatic environments, like Paramecium, have a contractile vacuole to maintain homeostasis.

Based on what you know about the function of vacuoles, a vacuole helps an organism maintain homeostasis by

Answers

A vacuole helps an organism maintain homeostasis by storing ions, nutrients, and other materials necessary for the cell's metabolism.

What is vacuole?

A vacuole is a membrane-enclosed organelle found in the cytoplasm of eukaryotic cells. It is an important organelle that provides structure and maintains cellular homeostasis. Vacuoles usually contain a variety of substances, including water, ions, proteins, and other organic molecules. They can also function as storage compartments, breaking down protein aggregates or storing materials that are important for cell survival.

In single-celled organisms like Paramecium, the contractile vacuole also helps maintain homeostasis by pumping excess water out of the cell to prevent it from becoming too full. In plants, vacuoles also help to regulate the turgor pressure of the cell, which helps to maintain the shape of the plant cell and its overall structure.

Answers

It seems that you have provided a series of statements about the genotypes of different individuals at two genetic loci, the b locus and the d locus. Each genetic locus can have two alleles, and the combination of alleles present in an individual's genotype determines their physical and behavioral traits.

What is genotype?

Genotype refers to the genetic makeup of an individual, specifically the set of alleles that an individual carries for a particular trait or traits. An allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same location on a chromosome. Each individual has two copies of each gene, one inherited from each parent, and thus can have two copies of the same allele or two different alleles.

Here,

Based on the information provided, we can make some observations: At the b locus, both parents were bb. This means that both parents had two copies of the recessive b allele, and all of their offspring will inherit one b allele from each parent, resulting in a genotype of bb.

At the d locus, one parent was dd and the other was dd. This means that both parents had two copies of the recessive d allele, and all of their offspring will inherit one d allele from each parent, resulting in a genotype of dd.

At the b locus, one parent was bb and the other parent could have had any genotype (bb, Bb, or BB). This means that one parent had two copies of the recessive b allele (bb), and the other parent could have had two copies of the recessive b allele (bb), one copy of the recessive b allele and one copy of the dominant B allele (Bb), or two copies of the dominant B allele (BB). The genotype of the offspring will depend on the genotype of the other parent.

At the d locus, both parents were dd. This means that both parents had two copies of the recessive d allele, and all of their offspring will inherit one d allele from each parent, resulting in a genotype of dd.

The other statements simply repeat some of the information provided earlier, so we can make the same observations as above.

It's worth noting that we can't make any predictions about the physical or behavioral traits of the individuals based solely on their genotypes at these two loci, since we don't know which genes are associated with which traits.

that Rosalind Franklin was not robbed of the Nobel Prize

Answers

Below the Answer


Rosalind Franklin was an important and influential scientist who made significant contributions to the field of molecular biology. However, the notion that she was "robbed" of the Nobel Prize is not entirely accurate. While her work on X-ray crystallography helped to identify the structure of DNA, it was not the sole factor in the discovery. Additionally, the Nobel Prize is awarded to a maximum of three people, and the prize was awarded to James Watson, Francis Crick, and Maurice Wilkins, who all made significant contributions to the discovery of the DNA structure.

It is important to acknowledge that the scientific community is built on collaboration, and no single person can take credit for a discovery. Franklin's work was certainly valuable, but she was not the only scientist working on the problem. Watson, Crick, and Wilkins all made important contributions to the discovery of the DNA structure, and it was their combined efforts that led to the breakthrough. Furthermore, Franklin's untimely death in 1958 meant that she was unable to receive the Nobel Prize even if it were to be awarded to her.

Ultimately, while Franklin's contributions to the discovery of the DNA structure were important, it is inaccurate to say that she was "robbed" of the Nobel Prize. The award was given to the scientists whose work led to the discovery, and Franklin was unfortunately not alive to receive the prize even if it were to be awarded to her. It is important to acknowledge the contributions of all scientists involved in a discovery, rather than assigning sole credit to one individual

Which of the following is not good direct evidence that the cell-cycle control system is conserved through billions of years of divergent evolution? (EXPLAIN YOUR RATIONAL FOR EACH ONE)
(a) A yeast cell lacking a Cdk function can use the human Cdk to substitute for its missing Cdk during the cell cycle.
(b) The amino acid sequences of cyclins in plants are similar to the amino acid sequences of cyclins in humans.
(c) The Cdk proteins in humans share conserved phosphorylation sites with the Cdk proteins in yeast.
(d) Yeast cells have only one Cdk, whereas humans have many Cdks.

Answers

Answer: The statement that is not good direct evidence that the cell-cycle control system is conserved through billions of years of divergent evolution is option (d) - "Yeast cells have only one Cdk, whereas humans have many Cdks."

Explanation:

The cell cycle control system is a highly conserved and regulated process, and the presence of similar proteins across different species is one way to demonstrate its conservation through evolution. The other three options (a, b, and c) all provide evidence of this conservation.

Option (a) indicates that the human Cdk can substitute for a missing yeast Cdk during the cell cycle, which suggests that the two proteins share similar functions and mechanisms.

Option (b) indicates that the amino acid sequences of cyclins in plants and humans are similar, further supporting the conservation of the cell-cycle control system.

Option (c) indicates that the Cdk proteins in humans and yeast share conserved phosphorylation sites, which suggests that they have similar regulatory mechanisms.

In contrast, option (d) implies a difference between yeast and human Cdks, which is not consistent with the idea of conservation. However, it should be noted that the conservation of the cell-cycle control system does not require that all aspects of the system are identical across different species

Answer:

The structure that develops within the reproductive leaves of a seed plant and contains the female gametophyte is called the ovule.

Explanation:

The ovule is the precursor to the seed, and it contains the female reproductive cells of the plant, including the egg cell.

After fertilization, the ovule develops into a seed, which contains an embryo and a food source for the developing plant.

The ovule is an important part of the reproductive system of seed plants, including gymnosperms and angiosperms.
