Which organelle is labeled A??? ^^ I’m sorry I honestly suck at biology lol

Blue-green algae, bacteria, and mycoplasma are prokaryotes. Bacteria are the most prevalent and fastest-growing prokaryotes.

Unlike prokaryotic cells, eukaryotic cells contain interior cellular bodies. Prokaryotes include different forms of bacteria and archaea. Eukaryotes include protists, fungi, plants, and mammals (everything except prokaryotes).

These single-celled organisms are present across the entire planet, from the dirt to human tissue. They differ in their architecture and shapes. The element of the cell wall that gives it structure is called peptiddoglycan. A few of the distinguishing features of bacteria are pili, flagella, and capsules.

Explanation:

One strength of using comparative morphology as evidence for phylogeny is that it provides a direct comparison of physical characteristics of organisms.

A. The phylogenetic tree that is the most accurate is likely tree B. This is because it is based on the greatest number of neutral mutations in the cytochrome c protein. The more neutral mutations that have occurred between two organisms, the longer they have been diverged from a common ancestor. Tree B shows the most neutral mutations between the organisms and therefore represents the most accurate depiction of the evolutionary relationships.

B. According to the data table, the organism most closely related to the penguin is the albatross. This is because the albatross shares the most neutral mutations with the penguin in the cytochrome c protein. The more mutations that two organisms share, the more recently they diverged from a common ancestor.

C. Two types of evidence other than comparing amino acid sequences that can be used to determine phylogeny of organisms are fossil records and comparative morphology. Fossil records provide evidence of extinct organisms and can help to determine when organisms diverged from a common ancestor. Comparative morphology involves comparing physical features and structures of organisms to determine their evolutionary relationships.

D. One strength of using fossil records as evidence for phylogeny is that it provides a direct record of the evolutionary history of organisms. Fossil records can also provide information about extinct organisms that cannot be obtained from living organisms. However, a weakness of using fossil records is that they are rare and not always complete, which can make it difficult to accurately determine evolutionary relationships.

One strength of using comparative morphology as evidence for phylogeny is that it provides a direct comparison of physical characteristics of organisms. This can provide insights into the evolutionary relationships of organisms. However, a weakness of using comparative morphology is that physical features can be similar in unrelated organisms due to convergent evolution, which can lead to incorrect evolutionary relationships being inferred.

I remember doing a question like this in class while learning about natural selection. The 2 colorations of moth live in a habitat that originally supported the lighter variant due to the light-colored trees. When the industrial revolution began, the soot levels reversed this because the black moths were more camouflaged that the lighter ones. A way we could prove this was the amount of black dresses and dark colored clothing during the time, often due to the fact that lighter colored clothing would turn black by the time the wearer arrived home. The lighter colored moths simply died off a bit because of this.

The pathway that would be fully operational only in respiring bacteria is: the electron transport chain (ETC).

The ETC is an important metabolic pathway that is responsible for generating ATP through oxidative phosphorylation. This pathway involves a series of electron carriers that transfer electrons from NADH and FADH2 to oxygen, which is the final electron acceptor.

The energy released from this transfer is used to pump protons across the inner mitochondrial membrane, creating a proton gradient that drives ATP synthesis. Since ETC requires oxygen as the final electron acceptor, it can only be fully operational in respiring bacteria that have access to oxygen.

In contrast, anaerobic bacteria use alternative electron acceptors such as nitrate or sulfate to generate ATP. Thus, the ETC pathway is an essential pathway for the survival of aerobic bacteria and would be fully operational only in such bacteria that are capable of respiration.

When performing an acid-fast stain on gram-positive bacteria non-acid-fast bacteria, the appearance of the bacteria at the end of the stain can differ. Acid-fast bacteria will remain red, while gram-positive bacteria non-acid-fast bacteria will become colorless after staining and treatment with acid-alcohol solution.

The acid-fast stain technique is used to differentiate between bacterial cells that are acid-fast and those that are non-acid fast. It is used to identify acid-fast organisms such as Mycobacterium tuberculosis and Mycobacterium leprae, which cause tuberculosis and leprosy, respectively. Acid-fast bacteria have high lipid content in their cell walls that resist decolorization by an acid-alcohol solution in the staining process.

The acid-fast stain process involves staining a bacterial sample with a mixture of carbol fuschin, phenol, and heat, which penetrates through the lipid-rich cell wall and stains the bacterial cells red. After staining, the sample is treated with an acid-alcohol solution, which removes the stain from non-acid-fast cells, leaving acid-fast cells red in color. In gram-positive bacteria, the cell wall is composed of peptidoglycan, which does not have a high lipid content.

Therefore, gram-positive bacteria do not retain the carbol fuchsin dye during the acid-fast staining process, and after treatment with acid-alcohol solution, they become colorless. The appearance of the bacteria at the end of the stain, therefore, depends on whether they are acid-fast or non-acid fast.

A lumen is a hollow area or channel found inside a tube or tubular organ, like the intestine or a blood vessel.

Organs can be described as hollow or solid. Spleen, liver, and pancreas are examples of solid organs that typically bleed when damaged. When damaged, hollow organs like the gallbladder, stomach, intestines, and bladder leak their contents into the abdominal cavity, also known as the peritoneal cavity.

A lumen, or hollow passage way through which blood flows, exists in every type of vessel. Smaller lumens in arteries than in veins contribute to the maintenance of the blood's pressure as it moves through the body. The lumen's primary function is to convey materials within the body or between the inside and outside, including air, blood, fluids, food, and other materials.

The probability of the baby sponge being homozygous recessive blue (ss) is 1/4 or 25%.

The Punnett square for this scenario is given below

     Y   y

---|--------

S  | Yy  Yy

s  | ys  ys

In this Punnett square, the capital Y represents the dominant allele for yellow body color, and the lowercase s represents the recessive allele for blue body color.

SpongeBob is heterozygous for yellow body color, meaning he carries one dominant Y allele and one recessive s allele. SpongeSusie is homozygous recessive for blue body color, meaning she has two copies of the recessive s allele.

To determine the chances of the baby sponge being blue, we need to look at the possible combinations of alleles that the offspring could inherit from each parent. There are four possible combinations:

YY (yellow body color)

Ys (yellow body color)

sY (yellow body color)

ss (blue body color)

The probability of each combination occurring is:

YY: 1/2 (50% chance of inheriting a Y allele from each parent)

Ys: 1/2 (50% chance of inheriting a Y allele from SpongeBob and an s allele from SpongeSusie)

sY: 1/2 (50% chance of inheriting an s allele from SpongeBob and a Y allele from SpongeSusie)

Answer:

The biosphere includes all living components of the Earth. Plants, a part of the biosphere, pull water from the ground, part of the geosphere, for their use in the process of creating food. Water from the plants is incorporated into the atmosphere through a process called transpiration, where water from the plant evaporates and enters the atmosphere.

Explanation:

The biosphere facilitates the movement of water from the geosphere to the atmosphere through plants in a process called evapotranspiration.

The biosphere represents the portion of the earth with living organisms, the geosphere refers to the rocks, the soil, and the mineral portion of the earth, and the atmosphere refers to the layer of air that surrounds the earth.

Plants (biosphere) are able to absorb water from the soil (geosphere) using their roots. The water is conducted to different parts of plants where it is needed by special conducting tissues called xylems.

Excess water is excreted from the plants to the atmosphere through a variety of openings on various organs of plants such as stomata, cuticles, and lenticels in a process called evapotranspiration.

Force is describe as a push or pull on a body. It causes the motion of a body generally.

The venous end of the capillary is where reabsorption of fluid into the capillary takes place.

Osmotic pressure is the net force that propels reabsorption—the flow of fluid from the interstitial fluid back into the capillaries—into the body (sometimes referred to as oncotic pressure).

The blood's hydrostatic pressure is the reason behind this (which favors filtration out of the capillary is lowest in the venous end of the capillary.) Cationic Exchange Because capillary hydrostatic pressure (CHP) exceeds blood colloidal osmotic pressure, net filtration occurs close to the arterial end of the capillary (BCOP).

Due to the fact that CHP = BCOP, there is no net fluid movement around the middle. Near the venous end, net reabsorption takes place because BCOP is higher than CHP.

Explanation:

Cell:The structural unit of the life of an organism that performs metabolic activities to carry out life processes is termed cell. The DNA, RNA, cytoplasm, cell membrane, and ribosomes are several basic cell features.

Cell cycle stages:The term cell cycle refers to a regular sequence of events performed by the cell for growth, division, and duplication or replication.

1.Interphase: The stage of the growth period of the cell cycle in which the cell prepares for cell division or mitosis is called interphase.

2.Prophase: The mitosis begins in prophase involving the coiling of chromosome (condense chromatin) and nuclear membrane breakdown.

3.Metaphase: The mitosis stage of the cell cycle that includes the lining of chromosomes at the metaphase plate is called metaphase.

4.Anaphase: The anaphase involves the separation and migration of sister chromatids towards opposite ends of the cell.

5.Telophase: The end phase of mitosis in which new chromosomes decondense and formation of new nucleus membrane take place is called the telophase.

6.Cytokinesis: The separation of daughter cells incorporated with cytoplasm and organelles is called cytokinesis.

Option 1) .AB//ab  is the genotype of the heterozygous individual in P1  Parent  AaBb x  aabb. An organism's genotype is made up of all of its genetic components.

So heterozygous parent is AaBb  and second parent is homozygous recessive aabb.

b. Map distance between A and B gene = total number of recombinat / total number of individual x 100

AB and ab are parental whereas Ab and aB are recombinant.

Map distance between A and B gene =     ( Ab + aB )/(AB +ab +Ab +aB)  x 100

                  =    (37.4+38.1)/(12.6+11.9+37.4+38.1) x 100

                    = 75.5/ 100x 100= 75.5 map unit
