The immune system can function through a generalized defense against pathogens called _____.

Answer:

Since the Industrial Revolution, humans have been releasing CO2 from these fuels more quickly than it can be re-absorbed naturally through the carbon cycle resulting in higher levels of CO2 in the atmosphere. ... As the amount of CO2 in the atmosphere increases, it can trigger significant changes in climate.

Explanation:

Increasing carbon dioxide in the atmosphere threatens marine life by a. acidifying the ocean.

Increasing carbon dioxide in the atmosphere threatens marine life by acidifying the ocean. This phenomenon, known as ocean acidification, occurs when excess carbon dioxide dissolves in seawater, leading to a decrease in pH levels.

As the ocean becomes more acidic, it poses a significant threat to various forms of marine life, including shell-forming organisms like coral reefs, oysters, and other shellfish. The acidic conditions make it difficult for these organisms to build and maintain their calcium carbonate structures, essential for their survival and growth.

Additionally, acidification can also impact the food chain by affecting the development and survival of small planktonic organisms that serve as a crucial food source for many marine species.

As a result, the overall ecosystem balance and biodiversity of marine environments are at risk.

Explanation:

Animals and plants need to get rid of carbon dioxide (c02), this process is called respiration. Respiration happens when the plant/animal breaths in air and releases it as carbon, carbon then moves from fossil fuels to the atmosphere where they are burned. When humans burn fossil fuels to power cities, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.

Answer:

The answer you are looking for is A

The bacteria share the same genetic code with animal, plant, fungus and Protista. The correct option is A.

The set of instructions utilized by living cells to convert data from genetic material contained in proteins is known as the genetic code.

Codons, or words, are the four letters that make up each of the three-letter words that make up a codon in DNA.

The order of bases in DNA or RNA makes up the genetic code. Codons are formed by groups of three nucleotides, and each codon represents one amino acid (or start or stop).

Following the start codon, the codons are read one after the other until a stop codon is reached. The genetic code is unambiguous, redundant, and universal.

The genetic code of bacteria is the same as that of plants, animals, fungi, and protists.

Thus, the correct option is A.

Answer:

Axon terminal ; dendrite

Hope this answer correct :)

Neuron A communicates with neuron B, and the axon terminal of neuron A releases a signal that activates the receptors present on neuron B. The neurotransmitters are attached to the ligand-gated channel on neuron B.

The nerve impulse transmission takes place between two neurons, and then in this way, from the sensory organs, the message passes to the spinal cord and the brain. The synapse is formed between the two neurons, such as the presynaptic neuron that releases the neurotransmitters, and this activates the ligand-gated channel of the postsynaptic neuron. Due to this interaction, the neurons get excited and activated.

Hence, neuron A communicates with neuron B, and the axon terminal of neuron A releases a signal that activates the receptors present on neuron B. The neurotransmitters are attached to the ligand-gated channel on neuron B.

Explanation:

I'm not too sure about "protein site," but I hope the rest helps!

Answer:

DNA is composed of sugar, phosphate and four nitrogen bases (A, T, G, C). During transcription, DNA is made into a molecule of RNA, which will travel to the ribosomes in the cytoplasm. Here, three bases, called a codon, will determine what amino acid is added to the chain. This chain will fold into a protein. This shape of this molecule determines how it functions.

Changes in the DNA code are called mutation and they can cause a protein to not function properly. A single change in the DNA of the hemoglobin gene will cause sickle cell anemia.

Explanation:

Adenine (A), Cytosine (C), Guanine (G), and Thymine are nitrogen bases. A and T pair together while C and G pair together. In DNA/RNA pairings, A pairs with Uracil (U). Transcription happens in the RNA, which is sent from the nucleus to the ribosomes (where protein is made). The three bases are called codon, their three base pairing is called an anticodon.

DNA gets mutated and this causes changes in the code. Sickle cell anemia occurs in the hemoglobin.

In spermatogenesis, the spermatogonium with diploid chromosomes, yields four final spermatids with haploid chromosomes by a process known as meiosis.

Spermatogenesis is the process by which spermatozoa are produced in the male gonads. It occurs in the testis and results in the development of fully mature spermatozoa capable of fertilizing an ovum. Spermatogenesis is a multi-step process that begins with the mitotic division of the spermatogonium. The resulting cells, known as primary spermatocytes, undergo meiosis I to produce two secondary spermatocytes, which then undergo meiosis II to yield four haploid spermatids. During spermiogenesis, the spermatids differentiate into spermatozoa.

In spermatogenesis, the spermatogonium with diploid chromosomes yields four final spermatids with haploid chromosomes by a process known as meiosis. Meiosis is the process by which the chromosome number is reduced from diploid to haploid. During meiosis, the chromosomes duplicate and then pair up. The paired chromosomes exchange genetic material, resulting in a reshuffling of genetic information. Finally, the paired chromosomes are separated, resulting in two daughter cells with half the chromosome number of the parent cell. This process occurs twice during meiosis, resulting in four haploid daughter cells.

Dietary fibers from foods such as oatmeal, brown rice, and popcorn are beneficial because they slow down the digestion of carbohydrates. So, option E is accurate.

Fiber-rich foods contain complex carbohydrates that are not easily broken down by digestive enzymes. As a result, these fibers slow down the digestion process, leading to a gradual release of glucose into the bloodstream. This slower digestion helps regulate blood glucose levels and prevents rapid spikes in blood sugar. Additionally, dietary fibers add bulk to the stool, promoting regular bowel movements and aiding in digestive health. However, it's important to note that fibers do not directly digest cellulose, but they contribute to overall digestive health and the elimination of waste.

Answer: Hijacking of host cell's metabolic action

Answer: D is the answer.

Explanation:

Option C is the correct answer. The Sun heats waters near the equator, which then move toward the poles where the waters cool.

The energy provided by the Sun affects global ocean currents by heating the waters near the equator, which then move toward the poles where the waters cool.

This process is known as the "thermohaline circulation" or "ocean conveyor belt." As warm water moves toward the poles, it cools and becomes denser, causing it to sink to the bottom of the ocean. This sinking action pulls cooler water from higher latitudes towards the equator, where it is heated and the cycle repeats. The ocean currents, in turn, affect global climate patterns by transporting heat from one region to another, regulating temperatures, and distributing nutrients and oxygen to marine ecosystems.

The bone that bears the body weight when you sit in a chair is the ischium. The ischium is a triangular-shaped bone that forms the lowest and back part of the hip bone, which supports the weight of the body when you are sitting. The ischium has a rough, knobby surface that provides a strong attachment point for the muscles that move the thigh and hip, such as the gluteus maximus and adductor magnus.

The ischium has a rough, knobby surface that provides a strong attachment point for the muscles that move the thigh and hip. The gluteus maximus, which is the largest muscle in the buttocks, attaches to the back of the ischium. The adductor magnus, which is a muscle in the inner thigh, attaches to the lower part of the ischium. These muscles work together to move the thigh and hip, as well as to support the weight of the body when sitting.

It is important to note that the ischium is not the only bone involved in supporting body weight while sitting. The pubis and ilium also contribute to the formation of the hip bone, which acts as a stable base for the pelvis and spine. The femur, or thigh bone, connects to the hip bone and bears the weight of the leg. In summary, the ischium bears the body weight when sitting in a chair, but it is just one part of the complex system of bones and muscles that work together to support the body during everyday activities.
