Vector-borne diseases are human illnesses caused by parasites, viruses and bacteria that are transmitted by vectors.

Infections known as vector-borne illnesses are those that are spread by the bite of an infected species of arthropod, including mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. Being cold-blooded (ectothermic), arthropod vectors are particularly susceptible to climate influences. Mosquitoes can transmit the Zika virus, West Nile virus, Chikungunya virus, dengue, and malaria to humans. Direct touch, droplets, a vector like a mosquito, a vehicle like food, or the airborne route are all possible modes of transmission.The tick is the most prevalent vector. Mosquitoes are the most prevalent and are the primary carriers of many dangerous illnesses.

Explanation:

The fact that the soil did not change significantly after five years, while the tree gained 74 kg, suggests that the tree's mass did not come from the soil alone. If the tree had gained all its mass from the soil, the soil would have lost an equivalent amount of mass, which did not occur. Therefore, this evidence suggests that the mass of a tree does not come solely from the soil.

While sunlight is necessary for photosynthesis, which allows the tree to produce glucose, the mass of a tree does not come directly from sunlight. Rather, the tree uses the glucose produced during photosynthesis to build its own tissues, such as leaves, branches, and roots. Therefore, while sunlight is necessary for the tree to grow, it is not the source of the tree's mass.

The tree's increase in mass is primarily due to the process of photosynthesis. During photosynthesis, the tree uses energy from sunlight to convert carbon dioxide and water into glucose, which it then uses to build new tissues. Additionally, the tree may have also taken up nutrients, such as nitrogen and phosphorus, from the soil, which it incorporated into its tissues. However, it's important to note that the majority of the tree's mass comes from the carbon that it takes up during photosynthesis, rather than the nutrients in the soil.

Cellular respiration?

Explanation:

The cell would cease dividing and be prevented from going through mitosis.

Higher eukaryotes have several cyclins as well as multiple Cdc2-related protein kinases that regulate their cell cycles. The term "Cdk's" refers to these Cdc2-related kinases (for cyclin-dependent kinases).

Cyclins collaborate with an enzyme family known as cyclin-dependent kinases to control the cell cycle's activities (Cdks). A Cdk that is not bound to a cyclin is inactive, but when it is, it becomes a functioning enzyme that can alter target proteins.

Cats have evolved certain behaviors that are influenced by their natural instincts and experiences.

When a cat sees milk, it may be attracted to it because it contains nutrients that are important for its survival, and the cat may associate the presence of milk with positive experiences. This can include nursing from its mother as a kitten or catching and consuming prey that contains milk or milk products.

On the other hand, when a cat sees a stick, it may perceive it as a threat or danger, and may associate it with negative experiences, such as being hit or attacked by a predator. This can trigger the cat's natural instinct to flee or hide from potential danger, as a survival mechanism.

Overall, a cat's behavior is influenced by its instincts, past experiences, and environmental cues. It may approach things that it perceives as positive or beneficial, and avoid or flee from things that it perceives as dangerous or threatening.

Both dichotomous keys and genetics (DNA) can be used as tools to classify organisms, but the accuracy of classification depends on the context in which they are used.

Dichotomous keys are useful for identifying and classifying organisms based on observable physical characteristics, such as their shape, color, size, and other morphological features. These keys work by providing a series of paired statements that help the user narrow down the possible identification of an organism until a final identification is reached. Dichotomous keys are particularly useful for identifying and classifying organisms that are difficult to differentiate based on external characteristics.

On the other hand, genetics (DNA) is a more accurate way to classify organisms at the molecular level. DNA analysis allows scientists to compare the genetic information of different organisms and identify similarities and differences in their DNA sequences. By comparing the DNA sequences of different organisms, scientists can determine their evolutionary relationships and classify them into different groups. DNA analysis is particularly useful for identifying and classifying organisms that are difficult to differentiate based on external characteristics or for organisms that have evolved to look similar to each other.

In summary, both dichotomous keys and genetics (DNA) are useful tools for classifying organisms, but DNA analysis is generally considered to be a more accurate way to classify organisms as it provides a more detailed and precise understanding of their evolutionary relationships.

In Activity 2, the respirometer C serves as the control. A control is an essential part of any scientific experiment as it provides a baseline against which the experimental results can be compared.

Respirometer C containing only plastic beads does not contain any living organisms and therefore does not undergo cellular respiration. By comparing the results of respirometers A and B with the control (respirometer C), any changes in oxygen consumption and carbon dioxide production can be attributed to the metabolic activity of the germinated beans in respirometer A and the dormant beans in respirometer B.

This allows researchers to determine the specific effects of germination on cellular respiration by isolating the variables and eliminating any external factors that could influence the results.

Membrane proteins transfer genetic information to the cytoplasm.

Explanation:

Membrane proteins cannot transfer genetic information to the cytoplasm. Genetic information is only in DNA and RNA, and to pass it, RNA has to leave the nucleus and be translated into a protein in the cytoplasm. Once the protein synthesis has finished, the protein may go to the membrane if it has the signal to do it or have a different function. In the membrane, the membrane protein can receive information from other cells and transfer it to the cytoplasm, but never in the shape of genetic information.
