A scientist has discovered a new gene in oysters. Oysters with the dominant allele for disease resistance 'R' have been found to tolerate polluted waters better than oysters with the recessive 'r' allele. What term is used to describe an oyster that has two identical dominant alleles (RR) for this gene?

A) genetic hybrid
B) homozygous dominant
C) heterozygous dominant
D) heterozyous recessive

Answers

the answer is B I believe

The right answer is B) homozygous dominant

We speak of homo / heterozygosity about a locus, that can be represented by several alleles (version). The alleles are dominant or recessive between them.

*So homozygote: same alleles

*heterozygote: different alleles


Consider a locus and 2 alleles:

allele R: dominant

allele r: recessively


*heterozygote: R / r

*homozygous recessive: r / r

*homozygous dominant: R / R

When a material changes size as a temperature changes, it is called _____

Answers

Final answer:

Thermal expansion is the term used to describe the change in size of a material due to temperature changes. It happens because of the increase or decrease in the kinetic energy of particles within the material. As temperature rises, substances expand in length, area, and volume, while they contract when cooled.

Explanation:

When a material changes size as a temperature changes, it is called thermal expansion. Thermal expansion is the increase, or decrease, of the size (length, area, or volume) of a body due to a change in temperature. For most substances, an increase in temperature usually results in an expansion, while a decrease in temperature can cause a contraction. This property is significant because it affects various applications and structural designs, such as bridges and railroads which have expansion joints allowing them to freely expand and contract with temperature changes.

The fundamental cause of thermal expansion is the increase in the kinetic energy of the atoms or molecules within a substance as the temperature rises. As materials are heated, they tend to expand in all dimensions; their lengths, areas, and volumes increase. This is true for solids, liquids, and gases, with gases experiencing the largest expansion relative to their size. Similarly, when the temperature drops, substances generally contract as the kinetic energy of their particles decreases.

Describe a plant’s circulatory system.
*There are no answer choices*
*I would appreciate it if you used accurate information, complete sentences, and make sure it makes sense*

Answers

A plant's circulatory system is the way for a plant to get carbon dioxide and nutrients to every cell in its system. It is also the way for a plant to get rid of toxins and waste from its system. In a plant's circulatory system, the nutrients a plant needs to survive travels upwards from the roots of the plan to the rest of it's system, and the toxins and waste is secreted from its extremeties located above the ground.

Answer:

Explanation:

Water and dissolved minerals enter a plant's roots from the soil by means of diffusion and osmosis. These substances then travel upward in the plant in xylem vessels. The transpiration theory ascribes this ascending flow to a pull from above, caused by transpiration, the evaporation of water from leaves. The long water column stays intact due to the strong cohesion between water molecules. Carbohydrates, produced in leaves by photosynthesis, travel downward in plants in specialized tissue, phloem. This involves active transport of sugars into phloem cells and water pressure to force substances from cell to cell.

What features of development indicate that echinoderms and chordates are more closely related to each other than they are to other animals

Answers

The features of development which indicate that echinoderms and chordates are more closely related to each other than they are to other animals are:

Their phyla belongs to the Deuterostomia clade of bilaterian animals.

What is a Feature of Development?

This refers to the characteristics which are good indicators that a particular species are progressive and can survive extinction and reproduce.

With this in mind, we can see that echinoderms and chordates are closely related because of their phyla which belongs to the deuterostomia clade of bilaterian animals.

https://brainly.com/question/19330334

The presence of deuterostome development, characterized by the formation of the anus before the mouth during embryonic development, is a key feature shared by echinoderms and chordates, indicating their closer evolutionary relationship compared to other animal groups.

Animals can develop along either of the two main developmental paths during embryonic development: the protostome or the deuterostome. Deuterostome development is seen in both chordates, which include vertebrates like fish, amphibians, reptiles, birds, and mammals, and echinoderms, which include sea stars, sea urchins, and sea cucumbers. The blastopore, the early gastrula stage's aperture, develops into the anus in deuterostome development, with the mouth forming later. This pattern differs from protostome development, in which the anus forms secondary to the blastopore, which develops into the mouth. The shared deuterostome development between echinoderms and chordates suggests a closer evolutionary relationship between these two groups compared to other animal phyla, such as arthropods (like insects and crustaceans) or mollusks (like snails and clams), which exhibit protostome development. This developmental similarity is considered a strong indicator of shared ancestry and evolutionary relatedness.

Is it better for a cell to have a large surface area to volume ratio or a small surface area to volume ratio.

A) Small: Because the cell has more contact with its surroundings.
B) Small: Because a cell with more volume has more space for its organelles.
C) Large: Because the cell has less contact with it surroundings.
D) Large: Because the cell has more contact with its surroundings and can better take in nutrients.

Answers

A and B don’t even make sense, (small doesn’t equal more contact or more space) C doesn’t either, (if it’s large it’s gonna have more contact space) so the best answer for me would be D. It’s the only one that seems logical.

when scientists refer to the DNA to RNA to proteins pathway, the RNA part of that pathway really represents three different types of rna: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). how is each type of RNA important to protein production

Answers

mRNA is transcribed from DNA and carries information needed for protein synthesis. During the translation phase of protein synthesis, the tRNA carry specific amino acids the the ribosome, and rRNA plays a role in the synthesis of the ribosome which is the site of translation phase of protein synthesis.

The main activity of RNA is to develop proteins through the process of translation. The three RNAs that takes place in the synthesis of proteins are mRNA, rRNA and tRNA.  

• The process of developing the molecules of proteins is known as protein synthesis. In biological terms, it comprises the synthesis of amino acids, translation, transcription, and post-translational events.  

• The mRNA or the messenger RNA is transcribed from DNA and carries information required for the synthesis of protein.  

• At the time of translation, the tRNA or the transfer RNA carry particular amino acids to the ribosome.  

• The rRNA or the ribosomal RNA performs the function in the synthesis of the ribosome, that is, the location where translation process takes place.  

Thus, the three RNAs, that is, mRNA, tRNA and rRNA performs an essential function in the synthesis of proteins.

What body part of the Galápagos finches appears to have been modified by natural selection?

Answers

The finches beaks because each finch had to have a different size beak for gathering food like you would need a larger beak for woodpecking and a smaller beak for gathering bugs. Darwin realized that all the finches though the same species had different beak sizes which had been slowly modified by natural selection because some types of finches couldn't find enough food with their beak size so over time they evolved to adapt to their habitat and they would be able to get more food because they could use a different type of beak.

what are the differences between a prokaryotic and Eukaryotic? and what are their functions?

Answers

This is the best i could do hope it helps!

Both organisms are composed of cells and each surrounded by a cell membrane. The largest difference between prokaryotic orgaisms and eukaryotic orgasims is that eukaryotic organisms have a nucleus. They also have organelles.!

The function of prokaryotic: Cells with genetic material and cell chemicals are all closed in by a cell wall, and have no organelles or nucleus, are called prokaryotes. Organisms in this group are mainly bacteria.

The function of Eukaryotic: Eukaryotic cells have a nucleus,so the cell's DNA is surrounded by a membrane. So, the nucleus holds the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.

In eukaryotes, the process of the cell division is called mitosis, true or false ?

Answers

True. Mitosis only happens in Eukaryotic organisms, although the process varies depending on the organism.

The given statement "In eukaryotes, the process of the cell division is called mitosis" is true. Because, mitosis is a type of cell division.

What is mitosis?

Mitosis is a type of cell division in which the chromosomes divide evenly into two identical groups. Mitosis is the method by which most cells divide in the body, including somatic (non-sex) cells and some cancerous cells.

Mitosis is responsible for cell growth and development, tissue repair, and asexual reproduction in organisms that do not reproduce sexually. Eukaryotic cells divide into two identical daughter cells through a cell division method known as mitosis.

The cell's nucleus divides during mitosis, which is followed by the division of the rest of the cell. Cell division is necessary for development, growth, and repair in multicellular organisms, as well as asexual reproduction in some single-celled organisms, which make exact clones of themselves by dividing.
