Q: Explain how the natural greenhouse effect works and then explain how humans have affected it.

Answer:

Since you didn't put answer choices, the answer you are looking for should be in the explanation.

Explanation:

Protein synthesis is needed to create new proteins for the cell. Proteins are essential because they perform functions for the cell, such as catalysis and communication, and form important structures like the cytoskeleton. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes these steps:

(1) Activation of amino acids:

(2) Transfer of amino acid to tRNA:

(3) Initiation of polypeptide chain:

(4) Chain Termination:

(5) Protein translocation:

Answer:

mRNA strand is formed, mRNA is processed, polypeptide chain is formed, protein is modified

Explanation:

Here it is:

1. DNA is used as a template to create mRNA

2. mRNA molecule binds to a ribosome

3. tRNA binds to the ribosome (specific tRNAs bring individual amino acids reading mRNA codons)

4. Amino acids are bonded together to make a poly peptide

5. The ribosome releases both the mRNA molecule and the polypeptide ( when it encounters translation termination codon on mRNA).

Skin color and height are examples of polygenic traits, which means that they are influenced by multiple genes. A polygenic trait is a trait that is controlled by two or more genes, and the effect of each gene is small.

Skin color is determined by the amount and type of pigments, such as melanin, produced in the skin. This polygenic trait is controlled by several genes, each with a small effect on the final outcome. Height is also a polygenic trait, Skin color is influenced by multiple genes and environmental factors. Many genes have been identified that play a role in determining height, but the exact number and Skin color they interact is not yet fully understood. In addition to genetics, environmental factors, such as nutrition and overall health, also play a role in determining polygenic trait an individual's height. Both Skin color and height, are complex traits and can't be determined by a single gene but by a combination of multiple genes and environmental factors.

Electrical activity in the human body interacts with electromagnetic waves outside the body to contribute to both eyesight and the sense of touch.

For eyesight, electromagnetic waves in the form of visible light enter the eye and interact with the specialized cells called photoreceptors located in the retina. When light waves reach the retina, they stimulate the photoreceptors, specifically the cones and rods. These photoreceptor cells convert the light energy into electrical signals through a process called phototransduction. The electrical signals are then transmitted through the optic nerve to the visual processing centers in the brain, where they are interpreted, resulting in the perception of vision.

Regarding the sense of touch, electromagnetic waves do not directly interact with the skin but rather with objects in the external environment. When you touch an object, pressure receptors in the skin called mechanoreceptors are stimulated. These mechanoreceptors convert the physical pressure applied to the skin into electrical signals, also known as action potentials. These electrical signals travel through sensory neurons to the somatosensory cortex in the brain, which processes and interprets the signals, allowing you to perceive the sense of touch.

In summary, electromagnetic waves in the form of visible light interact with photoreceptors in the eye, converting light energy into electrical signals for vision. For touch, electromagnetic waves indirectly interact by stimulating mechanoreceptors in the skin, which then generate electrical signals that are transmitted to the brain for the perception of touch.

Mia can organize the elements by level of organization as individual organisms (frogs, turtles, birds, squirrel, snake), populations (group of each species), communities (grasses, shrubs, wildflowers, rocks, algae, water plants), and ecosystem (including the stream and all the components mentioned).

One way Mia can organize these elements by level of organization is by utilizing the ecological hierarchy or levels of ecological organization.

This hierarchical framework allows for the classification of living and non-living components based on their organizational complexity and interactions.

Starting from the simplest level to the most complex, Mia can organize these elements as follows:

By organizing these elements using the ecological hierarchy, Mia can appreciate the interconnections and interdependencies among the different levels of organization within the park's natural environment.

Answer

The nervous and skeletomuscular systems help maintain homostasis by regulating respiration.

Explanation:

The brain stem, consisting of the pons and medulla, represent the main respiratory center.   According to Wikipedia, "an increased level of carbon dioxide in the blood, or a decreased level of oxygen, will result in a deeper breathing pattern and increased respiratory rate to bring the blood gases back to equilibrium."

This is an example of a homostastic response controlled by both of the organ systems referenced above.

The answer is b. 92. human white blood cells are often multinucleated. 92 chromosomes would be present in a white blood cell with two nuclei.

Each nucleus in a human white blood cell typically contains 46 chromosomes. Therefore, a white blood cell with two nuclei would contain a total of 92 chromosomes.

White blood cells, also known as leukocytes, are an important part of the immune system and are produced in the bone marrow. They can be either mononuclear or multinucleated, depending on the specific type of cell. However, regardless of the number of nuclei, each nucleus in a human cell contains the full complement of 46 chromosomes.

Answer:

10⁶

Explanation:

A 1:100 serial dilution is a dilution in which the concentration decreases 100 fold (i.e., in each dilution the concentration of the culture must be multiplied by 10⁻²). The question above indicates that a three-step 1:100 dilution was applied, which means >> 10⁻² x 10⁻² x 10⁻² = 10⁻⁶. Moreover, the dilution factor can be calculated by dividing the volume of the diluted solution by the volume of the concentrated solution. The dilution factor is the inverse of dilution, thereby in this case this value is equal to 10⁶ (dilution = 10⁻⁶ >> dilution factor = 10⁶).

In the forest, there is a diverse food chain that sustains various organisms. At the bottom of the chain are the producers, which in this case are the trees. They use photosynthesis to create their food and oxygen, providing a crucial foundation for the food chain.

Moving up the chain, we have the primary consumers, which are the herbivores that feed on the tree's leaves and fruits. The primary consumers in this food chain are the deer, who graze and browse on the trees throughout the forest.

Next in line are the secondary consumers, which are the carnivores that feed on the herbivores. In this food chain, the secondary consumers are the wolves, who hunt the deer for their sustenance.

Finally, we have the decomposers, which play a crucial role in breaking down dead organisms and waste into nutrients that can be used by the producers. In this food chain, the decomposers are the fungi and bacteria that break down the dead leaves and decomposing bodies of the deer and wolves, returning nutrients to the soil for the producers to use once again.

Answer:

The correct answer is - 2. decreasing ocean pH.

Explanation:

Many marine organisms such as corals that have hard calcium carbonate shells or skeletons are deteriorating due to the increase of carbon dioxide levels dissolved in marine water which leads to decreasing pH in seawater.

For example, increasing ocean acidification or decreasing pH level due to increased carbon dioxide has been shown to significantly reduce the ability to maintain their skeleton or hard structure or building again. Due to Co2 dissolving in the water means more hydrogen ions in seawater that leads to the concentration of CO3^2- ions actually decreases.

Nociceptors are sensory receptors that detect signals from damaged tissue or the threat of damage and indirectly also respond to chemicals released from the damaged tissue. Nociceptors are free (bare) nerve endings found in the skin, muscle, joints, bone and viscera.

Also called pain receptors, nociceptors are a set of sensory neurons with specialised nerve endings extensively distributed in the skin, deep tissues and most of the visceral organs of our body.

Nociceptors are equipped with specific molecular sensors, which detect extreme heat or cold and certain dangerous chemicals. Physiological pain responses normally protect us from tissue damage by rapidly alerting us to impending injury.
