Organisms are classified taxonomically. One of these classifications is the kingdom. There are 5 kingdoms: animalia (animals), plantae (plants), fungi (fungi), monera (prokaryotes), and protista (other eukaryotes).
The kingdom protista specifically harbor eukaryotes that cannot be classified in the other kingdoms (plantae, animalia, fungi), some examples are algae, protozoa, or amoebae.
Because bacteria are prokaryotes (monera kingdom). The answer is C "eukaryotes".

Why do you need to control your exposure to X-rays?
Answers
X-ray radiation can destroy molecular structures and possibly cause injury when it is absorbed by our bodies. Skin burns, hair loss, and a rise in cancer incidence are signs that very high radiation doses harm human cells.
Typically, the radiation exposure you receive during an X-ray radiation is comparable to between a few days and a few years of exposure to environmental radiation. Although the possibility of developing cancer many years or decades after being exposed to X-rays is acknowledged, it is believed to be extremely low. An x-ray requires that you remain motionless. Images can become hazy due to motion. When the picture is being taken, you could be requested to hold your breath or remain still for a brief period of time.Your radiation exposure will be decreased if you stay inside. Window and door locks should be closed. Shower or use a moist cloth to cover any exposed skin.

A gummivore is an animal (in this case, a primate) with a feeding strategy that depends on the sap or gum from trees. It is a type of diet that consists primarily of exudates. Some adaptations observed in these species include: 1-specialized anterior teeth in order to stab bark; 2-well-developed claws for clinging to trees
Frugivores primates have a feeding strategy mainly based on raw fruits. Some adaptations observed in these species include 1-low rounded molar cusps and 2-broad incisors.
Folivore primates (also called leaf-eating monkeys) have a feeding strategy mainly based on leaves. Some adaptations observed in these species include 1-narrow incisors, 2-broad molars (high shearing crests), 3-thin enamel molars.
Vertical clinging and leaping is an arboreal locomotor pattern practiced by lemurs and tarsiers. These animals push off from one vertical support with their hindlimbs to land on another vertical support. Some adaptations observed in these species include 1-hips, knees, feet, arms, and tails that facilitate climbing and leaping, 2-large hip extensor muscles and 3-specialized minor muscles.

Blood Doping
Blood is a fluid tissue, which means that blood cells are suspended in a fluid called plasma. Blood tests are concerned with not only the number of blood cells present, but with the amount of plasma that surrounds the cells.
The diagram below represents tubes containing blood samples from an athlete before and after blood doping. Blood doping is an illegal practice reportedly used by some athletes a few weeks before an athletic event, and involves removing whole blood from an athlete, separating the oxygen-carrying red blood cells (RBCs), and then freezing them. These RBCs are thawed and returned to the athlete's body just before the athlete competes. Serious health risks are associated with this practice.
Explain why athletes who practice blood doping would be expected to perform better at an athletic event.
a. The practice increases the number of RBCs (red blood cells) that would carry more oxygen to muscle cells
b. They would have less energy because they have extra oxygen
c. Since muscle cells receive more oxygen for respiration, they would have less energy for the athletic event.
d. all of the above
Answers
Option A. The athletes who practice blood doping would be expected to perform better at an athletic event. The practice increases the number of RBCs (red blood cells) that would carry more oxygen to muscle cells.
What is blood doping?By increasing the number of RBCs, blood doping increases the amount of oxygen that can be transported to muscle cells, which is the critical factor for athletes' performance in aerobic activities. This increase in oxygen availability enables the athlete to perform at a higher intensity for a more extended period, ultimately resulting in better athletic performance.
The athlete would not have less energy because they have extra oxygen, and muscle cells receiving more oxygen for respiration would increase, not decrease, energy production. However, as mentioned, blood doping carries serious health risks, such as increased risk of heart attack, stroke, and blood clots, and is illegal in competitive sports.

Classification of organisms into three domains is based on:
A) the presence of a cell wall
B) the number of cells in the organism
C) cellular organization
D) nutritional requirements
Answers
Answer:
C
Explanation:
cellular organization is the components that make up the cell and how they are arranged inside it. Each component, called an organelle, performs a specific function that is vital for the cell.
The Bacteria, Archaea, and Eukarya are the three domains of the classification. The cellular basis of the classification of the three domains. Thus, option C is correct.
What is the cellular organization?The cellular organization is the arrangement of the cells that are the smallest unit of the organism. The cells of the body make groups at the hierarchical level and perform a specific function.
The domains are not classified based on the cell wall as the animal and plant cells are grouped in the eukarya together. They are also not organized based on the number of cells as bacteria and Archaea both are single-celled.
The domains are not classified based on the nutritional requirements as the modes of nutrition varies in the eukarya domain itself and not just the two other domains.

Cell adhesion molecules are the proteins that project from the pre- and postsynaptic membranes into the synaptic cleft to insure that the two cells remain in close proximity to one another.
Cell adhesion molecules are a diverse group of proteins that are involved in various biological processes, including the formation and maintenance of synapses between neurons. CAMs bind to specific receptors on the opposing cell membrane and help to hold the pre- and postsynaptic membranes together, allowing for efficient transfer of signals between the neurons.
There are several types of CAMs that are involved in synaptic adhesion, including neurexins, neuroligins, and cadherins, among others. These proteins play important roles in the development, function, and plasticity of synapses, and their dysfunction has been implicated in various neurological disorders.

4) Plasma Membrane
5) Cell Wall
6) Capsule
7) Pilus
8) Flagellum
Answers
Hello.
(1) Cytoplasm: The cell substance between the cell membrane and the nucleus, containing the cytosol, organelles, cytoskeleton, and various particles. The cytoplasm is responsible for cell shape, material transport like genetic material and products for cellular respiration, and storage.
(2) Plasmid: A segment of DNA independent of the chromosomes and capable of replication, occurring in bacteria and yeast: used in recombinant DNA procedures to transfer genetic material from one cell to another. In other words, it is a small, circular, double stranded DNA molecule, which can replicate independently from its chromosomal DNA. If plasmids are used for experiments, they are called vectors. because genes in plasmids often provide the bacteria with genetic advantages, including for example antibiotic resistance.
(3) DNA in nucleoid: The nucleoid is the region of a prokaryotic cell that houses the primary DNA. The nucleoid contains the genomic DNA, and molecules of RNA and proteins. The main proteins of the nucleoid are: RNA polymerase, topoisomerases and the histone-like proteins: HU, H-NS (H1), H, HLP1, IHF and FIS.
(4) Plasma membrane: The plasma membrane is a thin, flexible boundary between a cell and its environment that allows nutrients into the cell and allows waste and other products to leave the cell.
(5) Cell Wall: The definite boundary or wall that is part of the outer structure of certain cells, as a plant cell. It acts as a skeleton for plants, protects the internal contents of the cell, and regulates cell growth.
(6) Capsule: A pure sample that lasts forever and can be used for testing at any time in the future has been created by extracting and purifying the DNA contained within the capsule to remove any damaging enzymes that may break down the DNA over time.
(7) Pilus: (Simple: Pili are used to transfer DNA and for attachment to surfaces.)
(8) Flagellum: A long, hair-like, motile extension of the plasma membrane; in eukaryotic cells, it contains microtubules arranged in a 9+2 pattern. The movement of flagellum propels some cells through fluids.

Indicate which the following statements are true.
a. During glycolysis, glucose molecules are hydrolysed to yield CO2 and H2O
b. The cleavage of fructose 1,6-bisphosphate by phosphofructokinase yields two molecules of glyceraldehyde 3-phosphate.
c. When subjected to anaerobic conditions, glycolysis in mammalian cells continues and causes a buildup of pyruvate in the cytosol.
d. In the mitochondrial matrix, the pyruvate dehydrogenase complex produces CO2, acetyl-CoA and NADH.
e. Fatty acids can be transported into mitochondria and converted into acetyl-CoA, FADH2 and NADH
Answers
Answer:
The correct answer is: D
Explanation:
(a) This process does not occur during glycolysis, it occurs after glycolysis since pyruvate is generally accepted to be the last product of glycolysis
(b) Phosphofructokinase does not produce two molecules of glyceraldehyde 3-phosphate but rather produces of one molecule of glyceraldehyde 3-phosphate and dihydroxyacetone phosphate
(c) During anaerobic conditions in mammals, pyruvate is converted to lactate by the enzyme lactate dehydrogenase. It can actually cause the accumulation of lactic acid/lactate in the muscle which causes muscle fatigue but does not cause buildup of pyruvate in the cytosol.
(d) In the fate of pyruvate, the pyruvate dehydrogenase complex produces CO2, acetyl-CoA and NADH in the mitochondrial matrix. The acetyl-coA produced thereof serves as a precursor for the citric acid cycle.
